Calcium hydrogencarbonate is relatively stable below 0 degrees Celsius; it is easily decomposed at room temperature to obtain calcium carbonate solids. Briefly explain why fluidized bed equipment is preferred by users: The fluidized bed equipment is a batch system. The loading and unloading of the pallet is usually manually operated and labor intensive. The system has developed into a structure called a tunnel, which is generally indexed continuously by the floor drive device. The operation is faster and very popular with users. Vibrating Fluidized Beds Manufacturers Introduction Fluidized bed equipment is continuously operated, but it is still necessary to intermittently insert new carts before continuing to dry and remove the products. You can add systems to automatically load, stack, and empty trays, all of which can enhance your approach to a continuous conveyor drying system. At the same time, the dryer can dry various feeds in liquids and slurries into granules, agglomerates and solids (objects), which are very suitable for small volumes, and sometimes prove to be economically feasible and load-bearing. At the same time, its residence time is infinitely controllable. The high variance of the initial humidity can be adjusted by adjusting the residence time, the temperature can be controlled very effectively, and the slope and immersion performance can be provided for applications requiring it. The strategic placement of most controls The thermocouple is connected to a solid state temperature controller that regulates the heat source to achieve the desired operating temperature. Designed to meet demanding applications, it can be designed to raise temperatures up to about 600 degrees. Pallets, internals and even entire units can be made from advanced materials, including various grades of stainless steel, which are usually insulated and coated. Reduce heat loss. Vibrating fluidized bed manufacturers generally do not need any dust collection, and the required air flow and associated speed reduce the possibility of entrainment and reduce carryover. However, if the product is very delicate, you can install a vacuum cleaner and control the emissions.

Three braking methods for vibrating fluidized bed dryers: 1. The electromagnetic brake is to lock the shaft of the vibrating fluidized bed by mechanical means. The electromagnetic brake is normally started after SV and OFF. Otherwise, the amplifier may be overloaded. The dynamic brake is normally started after SV, OFF or the main circuit is powered off. Doing so may cause the dynamic braking resistor to overheat. 2. Regenerative braking means that the vibration fluidized bed feeds back the energy generated by the braking to the DC bus through the inverter loop during deceleration or stop, and is absorbed by the RC circuit. The regenerative braking must be performed when the servo is working normally. In the case of failure, emergency stop, power failure, etc., the vibrating fluidized bed cannot be braked, and the work is automatically performed by the system. 3. The dynamic brake is composed of dynamic braking resistor. When the fault, emergency stop and power supply are cut off, the mechanical feed distance of the vibrating fluidized bed is shortened by the energy consumption braking. The dynamic brake does not need power supply when working, and external relay control is required.

The difference between the application of different boiling dryers in the industry: There are many kinds of boiling dryers and they are widely used in industry. This paper will start with the principle of boiling dryer and compare the characteristics of several boiling dryers. Boiling dryer, also known as fluidized bed, has been used and improved for more than 30 years. It is now more and more important in pharmaceutical, food, chemical, food and other aspects. However, the performance of different types of boiling dryers And the application is different. The definition of boiling drying: boiling drying, also known as fluidized drying, refers to the process of drying the solid particles in a fluidized state. The principle of boiling and drying: refers to the drying medium to dry the solid particles in the fluidized state. The basis of the material drying process is the boiling of the powder. At the same time, under the action of exhausting, the fine powder in the container is filtered through the collecting bag. The rear row is outdoors. During drying, due to gas-solid two-phase countercurrent contact, vigorous agitation. The solid particles are suspended in a drying medium and have a large contact surface area, which is excellent in heat transfer, mass transfer, volume dry strength, and thermal efficiency. Because of the better adaptability of boiling drying to various materials, it has smaller floor space, larger production capacity, higher thermal efficiency, easier operation control and less particle damage than other dryers. It is widely used nowadays, especially in the pharmaceutical industry. in. 1. Because the temperature distribution in the fluidized bed is uniform, thus avoiding any local overheating of the product, it is especially suitable for drying certain heat sensitive materials; 2. The residence time of the material in the dryer can be adjusted as needed, so the moisture content of the product is stable; 3. Continuous operation can be carried out in the same equipment, and intermittent operation can also be performed; 4. Since the contact area between the material and the drying medium is large, and the material is continuously stirred vigorously in the bed, the heat transfer effect is good and the heat capacity coefficient is large; 5. The drying device itself does not include mechanical moving parts, so the investment cost of the equipment is low and the maintenance workload is small.

It is a new type of continuous drying equipment that integrates drying, crushing and sieving. We all know that he has many advantages, but we still need to pay attention to some when purchasing. Matters, because the current production of flash dryers is more manufacturers, how to pick good and cheap in many suppliers is not easy. Before buying, we should first understand the basics of the flash dryer and we should consider the use of the flash dryer. Method / Step: 1. Physical and chemical properties of materials to be dried, material form, water content, water content, water of crystallization, particle size, bulk density, viscosity, heat sensitivity, softening point, phase transition point, thixotropic property, toxicity, corrosiveness, odor, flammability , explosive, electrostatic, gas permeability, agglomeration, easy comminution of crystals or particles, etc. will affect the drying effect 2.

Dry production requirements and long-term planning, the impact of material commodity value and drying effect, such as product moisture, pollution, temperature, wear, chalking, crushing, rehydration, etc. on the value of the commodity, the recovery rate of the material Claim. 3. Due to the same drying method, the heat energy consumed by drying and dehydrating one kilogram is basically the same, and the capacity of the heat source (hot air stove, steam radiator, etc.) of the dryer is also certain, so the main technical index of the dryer - drying capacity It is often based on the amount of dewatering per hour (or the amount of dehydration). This indicator is determined under certain conditions, such as wet material type, initial moisture content, final moisture content, hot air temperature, ambient temperature and humidity, and the like. As long as one of the conditions changes, it has an impact on the production capacity of the dryer, and sometimes the impact is still large. 4, wet material type Here refers to the combination of material and moisture. The wet material can be divided into capillary porous materials. The moisture is mainly combined with the capillary force, such as sand, silica, activated carbon, and ceramics. The bonding strength between moisture and materials is small, and drying is easy; colloidal materials, The combination of moisture and material penetration is dominant, such as glue and flour dough. The material generally exhibits high viscosity, and the combined strength of moisture and material is large, and drying is difficult. Capillary porous colloidal materials have the above two types of substances.

The higher the hot air temperature, the more heat energy is contained, and the lower the relative humidity of the hot air, the stronger the ability to absorb water and carry moisture, which is very favorable for drying, and the drying heat efficiency is also high. In many drying equipment, when the other conditions are constant, the dewatering capacity of the dryer is substantially proportional to the change in hot air temperature. When selecting the drying equipment, it is necessary to have sufficient data for the ultimate temperature of the damaged material. When the material permits, try to select the high temperature medium. In particular, many drying methods, especially rapid drying, the temperature of the dried material is much lower than the drying medium temperature.

Quartz sand drying equipment Features: ◎The drum dryer has a high degree of mechanization and a large production capacity. ◎The fluid passes through the cylinder with low resistance and low functional consumption. ◎ The adaptability to material properties is relatively strong. ◎ stable operation, low operating cost, and good uniformity of product drying. How to make the drum dryer achieve low loss and high efficiency? HZG rotary drum dryer is a cylinder with a slight tilting of the main body and adjustable speed within a certain range. The wet material is fed into the cylinder by the feeder, and the material is dry under the flapping device of the inner cylinder. The device is evenly distributed and dispersed and is in full contact with the hot air (cocurrent or countercurrent) passing through the cylinder, which accelerates the drying heat transfer and mass transfer. Thereby achieving the purpose of drying. How to make the drum dryer achieve low loss and high efficiency? 1. Pay attention to the use of cooling water: the fan and pump used in the drum dryer are large equipment, and the fan is basically running continuously, so the motor used is very easy to heat. Here we need to use water for cooling. . But today, environmental problems are getting worse, and water is also a scarce resource. At this time, we need to recycle the cooling water, which not only reduces the loss, but also saves water. 2, consider the use of thermal energy: drum dryer is the use of thermal energy to some of the equipment with high water content, can not meet the production requirements of the drying operation. Whether or not its thermal energy can be fully utilized has become a top priority. Usually, we use coal, diesel, natural gas and heating pipes to generate heat through specific equipment. These equipments generally include four types of coal-fired furnaces, fuel burners, gas burners and electric heaters. The use of coal-fired furnaces is relatively extensive, but most of them can only be used in applications where material requirements are not strict, and heat exchangers are required in applications where strict requirements are required. Burners are commonly used in large dryer equipment, which is highly automated and can significantly reduce labor. Electric heaters are generally only used in the laboratory and are an ideal device. 3, pay attention to the overall insulation of the drum dryer: drying work is mainly the use of thermal energy, then the full use of thermal energy has become an important one. Therefore, we must pay special attention to the insulation work of the tumble dryer. No heat loss can occur in any part. 4, the use of frequency converter: Fan is an important supporting equipment of the drum dryer, and its basic operation is continuous, its loss is very large. Here we have to use the frequency converter, we can artificially control the operation of the fan after using the frequency converter. In addition, the inverter can be added at the dust removal equipment. 5. Pay attention to the design of the hot air distributor: if the thermal energy wants to contact the wet material, it must pass the hot air distributor. How to design the hot air distributor is an important task, which directly affects whether the material drying can meet the requirements. 6. Always check, maintain and maintain the equipment to ensure that all bolt fasteners are not loose. Always pay attention to the contact between the raceway and the retaining wheel and the tug, the windshield, the gear cover without wing cracks and frictional damage. Waiting for the situation.

  • Nickel sulfate dryer
    What is nickel sulfate? Nickel sulfate is an inorganic substance, easily soluble in water, slightly soluble in ethanol and methanol, and its aqueous solution is acidic, slightly soluble in acid and ammonia, and toxic. Mainly used in the electroplating industry, it is the main nickel salt for electroplating nickel and electroless nickel, and also a source of metal nickel ions, which can dissociate nickel ions and sulfate ions during electroplating. Nickel sulphate dryer Working principle: The wet material is continuously fed from the feeder to the first layer of the drying tray on the upper part of the dryer, and the raking arm with the raking leaves is rotated to make the raking arm make a rotary motion so that the rakes continuously pluck the material. The material flows along the exponential spiral through the surface of the drying tray, the material on the small drying tray is transferred to the outer edge, and falls to the outer edge of the large drying tray below the outer edge. On the large dry tray, the material moves inward and falls from the middle. The material is dropped into a small dry tray as follows. The size of the drying tray is alternately arranged up and down, and the material is continuously flowed through the entire dryer. A heating medium is introduced into the hollow drying tray. The heating medium is in the form of saturated steam, hot water and heat transfer oil. The heating medium enters from one end of the drying tray and is led out from the other end. The dried material falls from the bottom layer of the drying tray to the bottom layer of the casing, and is then transferred to the discharge port by the rakes. The moisture fraction escapes from the material and is discharged by the moisture discharge port provided on the top cover, and the moisture of the vacuum type tray dryer is discharged by the vacuum pump port provided on the top cover. The dry material discharged from the bottom layer can be directly packaged.

  • Energy-saving and environmental protection printing and dyeing sludge drying machine
    Printing and dyeing sludge Description: Printing and dyeing sludge contains a large amount of organic pollutants, which will consume dissolved oxygen, destroy the ecological balance of water, and endanger the survival of fish and other aquatic organisms. Organic substances that sink under the water will generate harmful gases such as hydrogen sulfide due to anaerobic decomposition, which will deteriorate the environment. Therefore, the existence of printing and dyeing sludge poses a great safety hazard to human survival. Printing and dyeing sludge drying machine Equipment overview: The paddle dryer is a horizontal agitating continuous drying device based on heat conduction. Because the agitating blade is shaped like a paddle, it is called a paddle dryer. It is also called a trough dryer or a stirring dryer in foreign countries. Since the heat required for the drying of the device relies on heat conduction indirect heat exchange, the drying process does not require or require a small amount of gas to carry away the moisture. It greatly reduces the heat loss caused by the gas and improves the heat utilization rate. It is an energy-saving drying equipment. Printing and dyeing sludge drying machine Principle: The hollow blade dryer can indirectly heat or cool the paste, granular, powder, and slurry materials, and can perform unit operations such as drying, cooling, heating, sterilization, reaction, and low-temperature calcination. The special wedge-type agitating heat transfer paddle in the equipment has high heat transfer efficiency and self-cleaning function of the heat transfer surface. A wedge-shaped hollow blade is densely arranged on the hollow shaft, and the heat medium flows through the blade through the hollow shaft. The heat transfer area in the effective volume per unit is large, and the temperature of the heat medium is from -40 ° C to 320 ° C. It can be water vapor or liquid type: such as hot water and heat transfer oil. Indirect conduction heating, no air is carried away to remove heat, and heat is used to heat the material. The heat loss is only the heat dissipation to the environment through the insulation of the body. The wedge-shaped blade heat transfer surface has a self-cleaning function. The relative movement of the material particles and the wedge surface produces a scrubbing action, which can wash away the adhering material on the wedge surface, so that a clean heat transfer surface is maintained during operation. The housing of the paddle dryer is W-shaped, and two to four hollow agitator shafts are generally arranged in the housing. The housing has a sealed end cap and an upper cover to prevent material dust from leaking and collecting material solvent vapor. A baffle is arranged at the discharge port to ensure the height of the material level, so that the heat transfer surface is covered by the material and fully functions. The heat medium flows through the casing jacket and the hollow agitating shaft through the rotary joint, and the hollow agitating shaft has different internal structures according to the type of the heat medium to ensure a good heat transfer effect. Printing and dyeing sludge drying machine Features: 1. The energy consumption of the blade dryer is low: due to indirect heating, there is not a large amount of air carrying heat, and the outer wall of the dryer is provided with an insulation layer, which is more energy-efficient than the usual convection drying. 2. The blade dryer system has a low cost: it has a huge heat transfer surface in the effective volume, which shortens the processing time and reduces the size of the device. It greatly reduces the building area and building space. 3. Wide range of processing materials: Different heat media can be used to process both heat sensitive materials and materials requiring high temperature treatment. Commonly used media are: water vapor, heat transfer oil, hot water, cooling water, etc. It can be operated continuously or intermittently and can be applied in many fields. 4. Small environmental pollution: no air is used, and dust materials are rarely entrained. The solvent evaporation of the material is small and easy to handle. Closed loops can be used for contaminated materials or for conditions requiring recovery of solvents. 5, low operating costs: the device is operating normally, only 1 hour / day · people. Low speed mixing and reasonable structure. The amount of wear is small and the maintenance cost is low. 6. Stable operation: Due to the special compression-expansion agitation of the wedge-shaped blade, the material particles are fully in contact with the heat transfer surface. In the axial interval, the temperature, humidity and mixing gradient of the material are small, thus ensuring Process stability.

  • Alcohol residue dryer
    Which is good in Changzhou Drying Equipment Factory? Trust-Changzhou Suli Drying Equipment Co., Ltd., our company specializes in manufacturing aldose slag dryer, sugar aldehyde residue drying equipment, XSG flash dryer, our company adheres to the faith of honesty to serve every customer. Welcome to visit our factory! Sugar aldehyde slag Alcohol residue is a by-product of the sugar industry. It is an energy concentrate. There are two types of beet sugar residue and sugar residue. The fresh sugar residue contains more water. In dry matter, the sugar residue contains more than 30% protein, which is better than beet sugar. The slag is high and can be used as a protein supplement. Alcohol residue dryer Production process: 1. At the bottom of the dryer, the larger and drier pellets are mechanically broken by the action of the agitator. The particles with lower moisture content and smaller particle size are entrained by the rotating gas stream and further dried during the ascending process. Since the gas-solid two phases are rotating, the solid phase inertia is larger than the gas phase, and the relative velocity between the solid and gas phases is large, and the mass transfer heat transfer between the two phases is strengthened, so the dryer has high production intensity. 2. The wet material (such as filter cake) from the previous process is directly put into the feeder, and the screw feeder adopts stepless speed change, and the wet material is sent to the dryer for drying. Fresh air is introduced by the air filter, heated by direct or indirect heaters. The agitator at the bottom of the dryer rotates at a speed of about 200 rpm to 500 rpm to promote fluidization of the wet material. Flash dryer advantages: 1. The special cooling device and air pressure sealing device are installed at the bottom of the dryer to avoid the deterioration of the material in the high temperature zone at the bottom. It can effectively control the final moisture and fineness, and ensure the moisture content and fineness of the product are uniform by adjusting the feeding, hot air temperature and classifier. 2. It has fast drying speed, high efficiency, greatly shortened drying cycle and reduced energy consumption. The dryer is small in size and easy to install and maintain. This dryer has a good industrial quality compared to conventional methods. Alcohol residue dryer Working performance: 1 can handle paste, filter cake and other materials; because it is flashed, instantaneous drying, can be used to process heat sensitive materials; there is a stirrer in the drying chamber, while drying in high-speed airflow, can handle sticky materials. 2 unit products have low energy consumption. The dryer can dry high solid content materials at higher temperatures, which is lower than other many drying equipments. Compared to the spray dryer, the drying capacity is twice that of spray drying and the energy consumption is 1/3 of spray drying. 3 product yield is high, good quality. Taking dry H-acid as an example, the yield of 5% can be improved by flash drying, and the particle size is uniform and the water content is small. 4 particles are dispersed at high speed in a hot gas stream, with short drying time, high speed and high thermal efficiency. 5 The equipment is compact in structure, small in floor space, integrated in drying, crushing and grading. It is an organic combination of swirling technology, fluidization technology, spray technology and convection technology. It does not need to be crushed and sieved after drying, which simplifies. The production process saves power and equipment costs. 6 compact equipment, small footprint and high production efficiency. 7 The system is well sealed, protecting workers' health and reducing environmental pollution. Abnormal troubleshooting of the flash dryer: 1, gas inlet temperature, other under normal circumstances, the gas outlet temperature is high, slowly increase the feeder speed to increase the feed rate, so that the temperature of the gas outlet temperature drops to the need; on the other hand, the gas outlet temperature is low, Affect the moisture content and reduce the speed of the screw feeder, reduce the feed rate, and make the temperature of the gas outlet temperature required. 2. The temperature of the inlet of the flash dryer is very high. When the feed rate of the negative drying tower must be reduced, the feed rate is adjusted after the negative pressure tower is stabilized, and the outlet temperature is guaranteed to be 90 °C. 3. The system pressure is unbalanced, check whether the system is leaking or blocked, and whether the pressure measuring tube is blocked. 4. The bag dust collector exports natural gas powder to check whether a bag is detached or damaged, and replaced and repaired in time. 5. Sudden power failure for a long time, the dryer is cleaned to prevent the machine from being wet and hard, preventing the opening of the piston ring of the dryer, and then driving to affect the quality of the product. 6. If the system pressure suddenly increases, it cannot be eliminated, and the power supply is cut off immediately. The operator quickly leaves the working place of the flash dryer to prevent personal injury during venting.

After the material is dried, it is discharged from the discharge port, and the exhaust gas is discharged from the top of the boiling bed through the cyclone dust collector group and the bag filter to recover the solid powder and then emptied. Vapor, electric and hot blast stoves can be used (according to user requirements). Special dryer for ferric sulphate Working principle: The clean hot air is distributed into the bed through the valve plate, and the wet material entering from the feeder is boiled by the hot air. Since the hot air is in extensive contact with the material, the heat and mass transfer process is enhanced, so it can be dried in a short time. If the continuous type is used, the material enters from one end of the bed, and after boiling for several tens of seconds to several minutes, it automatically flows out from the other end of the bed. This equipment is generally operated under negative pressure. Special dryer for iron sulphate adapts to materials: ◎ Drying of pharmaceuticals, chemical raw materials, food, grain processing and feed. Such as: raw material medicine, tablet granules, Chinese medicine granules, health food, beverage granules, corn germ, feed, plastic resin, citric acid and other powder materials dry and dehumidification.

  • Rosin drying equipment
    What is rosin: Rosin is a non-volatile natural resin obtained from pine turpentine by different processing methods. Rosin is an important chemical raw material widely used in soap, paper, paint, rubber and other industries. Rosin application: Rosin is often used as a tackifying resin in hot melt, pressure sensitive and solvent based adhesives to increase initial tack and improve bond strength. Rosin also improves the dryness and peel strength of the aqueous acrylate laminating adhesive in an amount of 6% of the total monomer. Rosin is a weakly acidic substance. If the amount of SBS type universal glue or spray glue is too large, it will cause corrosion of the iron package, causing the glue to quickly turn brownish black, although it does not affect the bonding performance, but the appearance is Doubtful. Rosin is very sensitive to the action of light, heat and oxygen, especially the powder is very easy to oxidize, so the hoop is stored in a whole block to prevent oxidation and darken the color and change the performance. When the surface of the massive rosin is oxidized, an oxide film is formed to prevent further oxidation of the internal rosin. Moisture accelerates the rosin oxidation process and releases acetic acid upon deep oxidation.

  • Special drying equipment for aluminum sulfate
    What is aluminum sulfate? Aluminum sulfate, white orthorhombic crystal powder. In the paper industry, as a precipitant for rosin rubber, wax emulsion and other rubber compounds, as a flocculant in water treatment, it can also be used as an internal retention agent for foam fire extinguishers to produce alum, aluminum white raw materials, petroleum decolorization, deodorizer, and some Raw materials for drugs, etc. It is also possible to manufacture artificial gemstones and advanced ammonium alum. 1. Introduction of special drying machine for aluminum sulfate: The pulsed airflow dryer is characterized in that the pipe diameter of the airflow drying pipe is alternately reduced and enlarged. The pulse airflow drying tube can fully exert the high heat and mass transfer effect in the acceleration section to strengthen the drying process. The added material particles first enter the drying tube with small diameter, and the particles are accelerated. When the accelerated movement ends, the diameter of the drying tube suddenly expands, and the particles enter the drying tube with large diameter according to inertia. During the movement, the particles are decelerated due to the resistance until the end of the deceleration, and the drying tube is suddenly reduced, so that the particles are accelerated again, so that the pipe diameter is reduced and enlarged repeatedly, and the moving speed of the particles is alternately accelerated. Deceleration, the relative velocity and heat transfer area between the air and the particles are large, thereby enhancing the rate of heat and mass transfer. At the same time, the decrease in the airflow velocity at the large pipe diameter also increases the drying time. Second, special drying machine for aluminum sulfate Structural features: The drying strength is large, the equipment investment is small, the airflow drying treatment volume is relatively good, and the water evaporation capacity is from 50kg/h to 5000kg/h, which is not comparable to other drying equipment. High degree of automation and continuous operation. It is only necessary to control the feeding speed of the screw feeder, and the material is dried in a very short time (0.5~2 seconds), and the labor intensity is small. The material temperature is low. Although the air temperature is very high (up to 500 ° C), since the material is in a constant drying period, the surface temperature of the material can only be the air wet bulb temperature, so it is suitable for the drying of heat sensitive materials. The material is not in contact with the outside world and the pollution is small. The heating method can be arbitrarily selected. Our products can be supplied, steam heating (below 140 °C), electric heating mode (or both), coal-fired hot blast stove (below 300 °C), fuel hot blast stove (below 600 °C), users can choose according to the conditions. Third, special drying machine for aluminum sulfate Technical parameters: Special pulse airflow dryer, special drying machine for aluminum sulfate, safe operation procedure for aluminum sulfate dryer (1) Driving procedure All transmission equipments are flexible and normal through the disk transfer, and each position is ready, and the safety can be improved before starting the vehicle. (1) First start the induced draft fan, so that the butterfly valve is opened at the required scale to ensure the gas flow. (2) Start the air compressor, control and regulate the multi-channel compressed air to operate under the design pressure process conditions. (3) Open the bag pulse controller backflushing system and adjust the backflush frequency to ensure that the gas inlet pressure works between 0.5-0.6Mpa. (4) Before the wet material is put into the feed, the water content must be measured and put into the hopper, and the screw feeder is to be started. (5) Heating the coal-fired hot blast stove to gradually increase the air inlet temperature of the dryer. When the air outlet temperature of the dryer exceeds 110 °C, start the screw feed motor to adjust the feed rate to ensure that the outlet temperature is around 60 °C. stable. When the inlet temperature reaches 130-150 °C, the speed of the feed motor is readjusted, and the inlet and outlet temperatures of the dryer are controlled to operate under the design temperature process conditions. (6) Observe whether the equipment (and other parts) in the system are operating normally. (7) Sampling and testing After the quality of dry powder is qualified, it is packaged and stored. (two), parking procedures (1) First stop stopping the screw feeder feeding. (2) Continue to dry the remaining material in the dryer and take it out of the machine. After half an hour, stop the hot air furnace. After that, the induced draft fan is stopped. (3) Stop the air compressor and stop the baghouse backflushing system. (4) Stop the instrument control. (3) Possible abnormalities and exclusions: In the drying operation, the air flow, the air inlet and outlet temperatures, and the feed amount in the dryer are mainly controlled. The amount of feed is adjusted as a dependent variable. 1. When the gas inlet temperature is constant, other conditions are normal, when the gas outlet temperature is high, slowly increase the feeder speed to increase the feed amount, so that the gas outlet temperature is lowered to the required temperature; conversely, when the gas outlet temperature is low, the effect is dry. The moisture content of the product reduces the speed of the screw feeder, reduces the amount of feed, and raises the temperature of the gas outlet to the required temperature. 2. When the gas inlet temperature of the dryer is high, when the negative pressure in the drying tower is low, the feeding speed must be lowered. After the negative pressure in the tower is stabilized, the feeding speed is re-adjusted to ensure the outlet temperature is the design value. 3. When the system pressure is unbalanced, check whether the system has air leakage or blockage, and whether the pressure measuring tube is blocked. 4. When the bag dust collector gas outlet is a powder, check whether the bag is detached or damaged, and replace and repair it in time. 5. When the power is suddenly cut off for a long time, the dryer should be cleaned to prevent the wet material in the machine from being dry and hard, blocking the ring gap of the dryer, and driving the car to affect the product quality. 6. If the system pressure suddenly increases and cannot be eliminated, the power should be cut off immediately, and the operator should quickly leave the operation site to prevent personal injury when venting. 7. If the squib valve suddenly opens during operation, the personnel must be evacuated in the first time and the pilot fan should be turned off first and then the feeder should be turned off.
