Description

Technical Field

[0001] This invention relates to the field of material processing reaction equipment, and more specifically to a material reaction, drying, and sieving machine. Background Technology

[0002] In material processing, such as when surface insulation of metal powders is involved, it refers to the formation of a dense oxide film (insulating coating) on ​​the metal surface after specific treatment. This film effectively prevents the metal powder from further reacting with oxygen, water, or other corrosive media in the surrounding environment, thereby significantly slowing down the corrosion rate of the metal powder. This process can make the metal exhibit corrosion resistance properties similar to noble metals, namely, a lower corrosion rate and a higher electrode potential. Once the insulating layer is formed, it can self-repair to a certain extent even in adverse environments, continuing to protect the metal substrate from corrosion.

[0003] In existing material surface processing equipment, the processes of spraying, stirring, and drying metal materials are combined into a single piece of equipment to save reaction time and improve reaction efficiency. However, since the metal materials have not undergone standardized processing, the reaction liquid that is not attached to the metal materials is prone to high-temperature condensation, which makes it easy for the metal materials to clump together. When the metal materials are directly output later, the looseness of the metal materials is low, and further crushing is required. In essence, this still does not improve the processing efficiency of metal materials and is not conducive to the quality requirements of the final metal material output. Summary of the Invention

[0004] The material reaction drying and sieving machine of the present invention can effectively solve the problem that the processing equipment in the prior art is not conducive to improving the quality and efficiency of metal material output.

[0005] According to one aspect of the present invention, a reaction drying and sieving machine for processing materials is provided, with the end pointing in the direction of gravity as the bottom, comprising: The feeding mechanism is used to input materials; The reaction chamber is connected to the output end of the feeding mechanism and is used to receive the material output by the feeding mechanism, and to spray the material with reaction liquid and stir it. A drying system, connected to the output end of the reaction chamber, is used to receive the material output from the reaction chamber and heat and dry the material; A sieve is connected to the output end of the drying system and is used to receive the material output by the drying system, sieve the material, and output it.

[0006] In some embodiments, the feeding mechanism includes: The feed cylinder has a top and a bottom opening. A conveying pipe is provided between the top and the bottom opening and is connected to the feed cylinder for feeding materials. The bottom opening is connected to the reaction chamber. A dust removal device is installed in the feed cylinder; The dust removal device generates negative pressure suction, causing impurities carried by the material to be adsorbed and separated along the direction of the top of the cylinder, and the material is output to the bottom port by gravity.

[0007] Therefore, when the material passes through the feed cylinder, it can be dusted by the dust removal device before being output to the reaction chamber, which helps to improve the quality and efficiency of the reaction.

[0008] In some embodiments, the dust removal device includes a filter screen and a first negative pressure device. The filter screen is disposed inside the feed cylinder, and the first negative pressure device is disposed at the top of the cylinder. The first negative pressure device generates negative pressure suction, causing impurities carried by the material to be adsorbed onto the filter screen. Therefore, by using the negative pressure suction generated by the first negative pressure device to adsorb impurities from the material onto the filter screen, the material input time is not excessively increased, which helps to improve efficiency.

[0009] In some embodiments, the feed pipe or the feed cylinder is equipped with a second negative pressure device, which is connected to the feed pipe and generates negative pressure suction to adsorb the material into the feed cylinder. Thus, the material is fed into the feed cylinder by negative pressure suction, which helps to adsorb impurities from the material onto the filter screen.

[0010] In some embodiments, the reaction chamber includes: support; The cylinder is rotatably mounted on the support, and the cylinder has a cavity for containing materials; the top of the cylinder has an opening communicating with the cavity, and the cylinder has a sealed bottom. The material enters through the opening and reacts within the cavity. By rotating the cylinder, the opening is flipped, causing the material to be discharged from the opening.

[0011] Therefore, the bottom of the cylinder is sealed to prevent leakage of materials or reaction liquids during the reaction. Rotating the cylinder to pour out the materials facilitates more effective discharge of residual materials.

[0012] In some embodiments, a cover is also included, which is movably mounted on the support and covers the opening when the material reacts within the cavity. Thus, the cover acts to seal the opening during the material reaction, and the movable structure of the cover facilitates cylinder rotation without interference, improving automation.

[0013] In some embodiments, the reaction chamber further includes a stirring device for stirring the material and a rotating device for driving the cylinder to rotate, the stirring device and the rotating device having a common rotation axis acting on the cylinder.

[0014] Therefore, the stirring device is used to stir the materials to ensure a full reaction, and the rotating device is used to turn the cylinder over. Both have a common axis of rotation, which helps to save space and improve the effectiveness of stirring.

[0015] In some embodiments, the stirring device includes a stirring shaft and a first driving device, the output end of the first driving device being drivenly connected to the stirring shaft, the stirring shaft extending horizontally in the axial direction; the stirring shaft is provided with a plurality of connecting rods and a plurality of stirring elements, the stirring elements being disposed on the connecting rods, the stirring shaft rotating to drive the connecting rods and the stirring elements to rotate, the stirring elements rotating cyclically to the bottom of the cavity.

[0016] Therefore, the first drive unit is used to provide the power for stirring, and drives the connecting rod and stirring components to rotate through the stirring shaft to circulate and stir the material.

[0017] In some embodiments, the rotating device includes a bushing and a second driving device. The output end of the second driving device is throttle-connected to the bushing. The bushing is rotatably mounted on the support and connected to the cylinder. The stirring shaft is sleeved inside the bushing. Thus, the cylinder is rotated via the bushing and the second driving device, with the second driving device providing the power for tumbling.

[0018] In some embodiments, the drying system includes: The drying chamber is provided with a first feed inlet and a feed outlet arranged opposite to each other, an air inlet for inputting hot air flow, and an exhaust outlet communicating with the air inlet; the first feed inlet is connected to the output end of the reaction chamber; A third negative pressure device is installed in the drying chamber, and the input end of the third negative pressure device is connected to the exhaust port; The material enters the drying chamber from the first feed inlet and is discharged from the feed outlet along the first direction. The third negative pressure device generates negative pressure suction, causing hot air to enter the drying chamber from the air inlet and act on the material. The material is then discharged from the exhaust port along the second direction to the output end of the first negative pressure device. The first direction is opposite to the second direction.

[0019] Therefore, the material can be heated and dried in the drying chamber. The hot air enters the drying chamber through a hot airflow, and the hot airflow moves in the opposite direction to the material for more effective drying.

[0020] In some embodiments, a heater and a fourth negative pressure device are also included. The input of the fourth negative pressure device is connected to the heater, and the output of the fourth negative pressure device is connected to the air inlet. The hot airflow generated by the heater enters the drying chamber through the fourth negative pressure device. Thus, the heater provides a heat source to generate a hot airflow to the drying chamber, and the fourth negative pressure device accelerates the entry of the hot airflow into the drying chamber.

[0021] In some embodiments, a stirring device is included, the stirring device comprising: A third driving device is installed in the drying chamber; The stirring shaft is driven and connected to the output end of the third driving device; Multiple stirring rods are connected to the stirring shaft; The stirring shaft is driven to rotate by the third driving device, which in turn drives the stirring rod to rotate and stir the material.

[0022] Therefore, the stirring device is used to stir the material, and the material is heated and dried more effectively while being stirred.

[0023] In some embodiments, the sieve includes: A sieving device for screening materials has a second feed inlet and a discharge outlet arranged opposite to each other. The material is input from the second feed inlet and screened to the discharge outlet for output. The second feed inlet is connected to the output end of the drying system. The sieving device also has an air inlet and an air outlet arranged opposite to each other and connected to each other. A cooling device is used to generate a cold airflow that acts on the material, and the output end of the cooling device is connected to the air inlet. The cold airflow enters the screening device from the air inlet and exits from the exhaust port, so that the material is simultaneously cooled and screened to the discharge port for output.

[0024] Therefore, the sieving device is used to sieve the dried material to improve its looseness, and the cooling device is used to cool the material at the same time, so that the temperature of the material after output is more suitable for transportation and use.

[0025] In some embodiments, a fifth negative pressure device is also included. The input end of the fifth negative pressure device is connected to the output end of the cooling device, and the output end of the fifth negative pressure device is connected to the air inlet, so that the air inlet is connected to the output end of the cooling device through the fifth negative pressure device. Thus, the fifth negative pressure device is used to accelerate the cold airflow into the sieving device.

[0026] In some embodiments, the material is input into the sieving device from the second feed port and moves along a third direction to the discharge port for output, and the cold airflow is input into the sieving device from the air inlet and moves along a fourth direction to the exhaust port for output, wherein the third direction is opposite to the fourth direction.

[0027] As a result, the material and the cold air flow move in opposite directions, making the cooling effect of the material more obvious.

[0028] In some embodiments, the sieving device includes a screen frame and a vibrating device, the vibrating device being disposed on the screen frame, the screen frame having at least one layer of screen mesh located between the second feed inlet and the discharge outlet in the direction of gravity, the material passing through the screen mesh to discharge through the discharge outlet. Thus, the vibrating device drives the screen mesh to vibrate, thereby separating agglomerated material.

[0029] In some embodiments, a hopper is also included, which surrounds the feeding mechanism, the reaction chamber, the drying system, and the sieve; the hopper is equipped with an exhaust system for depressurizing the interior of the hopper and discharging excess gas. Thus, the hopper serves as the internal structure for processing material reaction drying sieves, and the exhaust system is used to depressurize and discharge excess volatile gases.

[0030] The material reaction drying and sieving machine of the present invention has the following advantages compared with the prior art: This application uses a feeding mechanism to input materials into a reaction chamber for physicochemical reaction, then a drying system to heat and dry the materials, and finally outputs them to a sieve for screening. Each process of the material processing has its own separate equipment. The materials are sprayed with reaction liquid, dried, and then further separated by a sieve. Therefore, the material processing steps are more complete, and the output materials are less likely to clump together and have a high degree of looseness, eliminating the need for additional crushing. This effectively improves the efficiency of material production. The entire process is completed automatically by automated equipment, which provides convenience for subsequent product processing.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] This invention relates to a material reaction drying and sieving machine, which can automatically feed, spray, dry, cool, and unload within a set process. The entire process is fully automated, requiring no manual intervention, and has a high degree of automation, effectively improving the processing efficiency of materials (reactions). This application can be applied not only to material passivation reactions and surface physicochemical reactions, but also to other material processing processes, such as sandblasting, oxidation, painting / coating, phosphating, and electroplating. Materials include soft magnetic metal particles, metal or non-metal powders, and other discrete raw materials. Furthermore, this material reaction drying and sieving machine is an intelligent mechanical device integrating spraying, drying, and sieving, achieving more effective compatibility of equipment performance and precise control. It adopts "INGOAL" The "PRO-IN" fully automatic computer control system has the following functions and features: fully automated operation without manual intervention; all operating parameters are controlled by a PLC, but manual parameter setting is also possible; real-time display of system and equipment operating status, fault information, and historical operating data; alarm display for critical parameter anomalies; and manual and automatic control mode switching. This application mainly focuses on the hardware implementation of this material reaction drying and sieving machine.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] Figure 1 A material reaction drying and sieving machine according to one embodiment of the present invention is schematically shown. Figure 1 As shown, the end pointing in the direction of gravity is the bottom (lower side), and the opposite is the top (upper side). The length direction is the left and right direction, which is orthogonal to the direction of gravity. The direction of gravity is represented as direction A, and the direction of gravity is direction B. This material reaction drying and screening machine includes a feeding mechanism 10, a reaction chamber 20, a drying system 30, and a screening device 40.

[0038] like Figure 2 , Figure 3 As shown, the feeding mechanism is used to input materials. The feeding mechanism includes a feeding cylinder 1 and a dust removal device. The feeding cylinder 1 is a metal cylindrical structure, assembled from various parts, and has a hollow interior. A cylinder top 11 is provided at the top of the feeding cylinder 1 to cover the top of the feeding cylinder 1, and a bottom opening 12 is provided at the bottom of the feeding cylinder 1 for outputting materials. The bottom opening 12 is generally connected to subsequent processing steps. The cylinder top 11 and the bottom opening 12 are arranged opposite each other in the direction of gravity. The bottom of the feeding cylinder 1 adopts a funnel-shaped structure to facilitate the smooth sliding of materials. A conveying pipe 13 is provided near the bottom of the feeding cylinder 1 for inputting materials transferred from the previous process. The conveying pipe 13 is located between the cylinder top 11 and the bottom opening 12 and is connected to the interior of the feeding cylinder 1. After entering through the conveying pipe 13, the materials can fall to the bottom opening 12 by their own gravity.

[0039] like Figure 4 As shown, the dust removal device is used to generate negative pressure suction to attract the internal force of the feed cylinder 1. The dust removal device includes a filter screen 101 and a first negative pressure device 102. The filter screen 101 is disposed inside the feed cylinder 1, located between the top 11 of the cylinder and the conveying pipe 13, that is, the filter screen 101 is located on the upper side of the conveying pipe 13. The filter screen 101 can adopt the filter screen 101 structure commonly used in the art. Preferably, the filter screen 101 is detachably connected to the inside of the feed cylinder 1. The filter screen 101 can be detachably separated by a snap-fit ​​structure, which facilitates the regular replacement and cleaning of the filter screen 101. The filter screen 101 can block the output of dust and other impurities, and allows airflow to pass through. The first negative pressure device 102 is used to generate negative pressure suction. It is set on the outside of the feed cylinder 1. The first negative pressure device 102 is specifically a negative pressure fan. It has an input end and an output end. The input end of the first negative pressure device 102 can be connected to the inside of the feed cylinder 1 through a conduit structure. The output end of the first negative pressure device 102 is the output end of the airflow. It can also be installed or extended to the outside by a conduit.

[0040] As can be seen, the conveying pipe 13 is the input end of the airflow. The first negative pressure device 102 generates negative pressure suction to drive the airflow output. The airflow direction in the feed cylinder 1 is from bottom to top. When in use, the material is input into the feed cylinder 1 and gradually falls to the bottom opening 12. The first negative pressure device 102 is activated to generate negative pressure suction, which adsorbs and separates the impurities on the surface of the material. The impurities will adhere to the filter screen 101 along the direction of the top of the cylinder 11 (the opposite direction of gravity). The filter screen 101 blocks the impurities from continuing to be output to the output end of the first negative pressure device 102. Therefore, the impurities can be quickly separated and will continuously adhere to and accumulate on the filter screen 101. The filter screen 101 can be replaced and cleaned regularly to achieve dust removal before the material enters the spray reaction liquid.

[0041] Furthermore, a second negative pressure device 14 is provided on the conveying pipe 13 or the feeding cylinder 1. In this embodiment, the second negative pressure device 14 is provided on the conveying pipe 13 and is used to adsorb and feed the material from the previous process. The second negative pressure device 14 is specifically a negative pressure fan, which is used to generate negative pressure suction on the conveying pipe 13. On the one hand, it can enhance the adsorption force of the dust removal device, so that impurities on the surface of the material can be more easily adsorbed onto the filter screen 101. On the other hand, it can also facilitate the acceleration of the feeding speed. Moreover, the second negative pressure device 14 can adsorb some of the impurities on the surface of the material in the conveying pipe 13, which is beneficial to further improve the dust removal effect.

[0042] Furthermore, such as Figure 3 As shown, an output cylinder 15 is provided at the bottom of the feed cylinder 1. The bottom end of the output cylinder 15 can serve as the output end of the feeding mechanism 10. The output cylinder 15 and the feed cylinder 1 can be fixedly connected. The output cylinder 15 is used to surround the bottom opening 12 to prevent the bottom opening 12 from spreading or leaking when outputting materials. The bottom end of the output cylinder 15 is generally connected to the input of the processing equipment of the next process, which can prevent dust and other impurities from the outside of the feed cylinder 1 or the outside air from contacting it. It can be seen that the bottom opening 12 is located inside the output cylinder 15. In this embodiment, the bottom opening 12 and the funnel-shaped bottom part of the feed cylinder 1 extend into the inside of the output cylinder 15, which facilitates the improvement of the support strength of the output cylinder 15 for the feed cylinder 1 and helps to improve the balance of the feed cylinder 1. The output cylinder 15 is provided with a vibration device 16 on the outside. The vibration device 16 is a vibrator, which can be referred to in the prior art. The vibrator can generate vibration on the output cylinder 15, thereby discharging and outputting the material remaining inside the output cylinder 15 through vibration. At the same time, the output cylinder 15 is fixedly connected to the feed cylinder 1. The vibration force generated by the vibration device 16 can be transmitted to the feed cylinder 1. That is, the vibration can also occur at the funnel-shaped structure at the bottom of the feed cylinder 1, which can facilitate the discharge of the material remaining on the inner wall of the feed cylinder 1.

[0043] In some embodiments, such as Figure 4As shown, the bottom opening 12 is provided with a swingable bottom cover 17. The shape of the bottom cover 17 corresponds to the bottom opening 12. The bottom cover 17 can abut against the bottom opening 12 to close the bottom opening 12 by swinging. In this embodiment, an automatic closing structure is adopted. Specifically, a bottom cover driving device 131 and a driving rod 132 are provided at the bottom of the feed cylinder 1. The bottom cover driving device 131 is preferably a motor. The output end of the bottom cover driving device 131 is driven and connected to the driving rod 132. The driving rod 132 adopts a rod-shaped structure. The free end of the driving rod 132 is connected to the bottom of the bottom cover 17. When the bottom cover driving device 131 is started, it can drive the driving rod 132 to swing, thereby driving the bottom cover 17 to swing, so that the bottom cover 17 can abut against the bottom opening 12 to close the bottom opening 12. Therefore, when the bottom opening 12 is closed, the feed cylinder 1 can have the function of temporary storage, and can also quantitatively control the amount of material output from the bottom opening 12, which is beneficial to improving the automation level of the process flow in the material reaction. The bottom cover 17 is also located inside the output cylinder 15. During the process of the bottom cover 17 swinging to open or close the bottom opening 12, the material may leak due to contact with the bottom cover 17. The output cylinder 15 can effectively surround the material to prevent leakage. The bottom cover drive device 131 can be set on the outside of the output cylinder 15. The output end of the bottom cover drive device 131 can extend to the inside of the output cylinder 15 and be connected to the drive rod 132.

[0044] Furthermore, an arc-shaped portion 171 is provided on the bottom cover 17. The arc-shaped portion 171 adopts an arc-shaped structure that protrudes on the bottom cover 17. It is set apart from the drive rod 132 on the bottom cover 17. The arc-shaped portion 171 can be made of a deformable elastic material. When the bottom cover 17 abuts against the bottom opening 12 to close the bottom opening 12, the arc-shaped portion 171 can extend into the bottom opening 12, which can further seal the bottom opening 12. The arc-shaped structure of the arc-shaped portion 171 is conducive to easy separation when separating from and abutting the bottom opening 12 and facilitates the deformation of the arc-shaped portion 171, thereby improving the adaptability of the bottom cover 17.

[0045] In some embodiments, such as Figure 3 As shown, a cleaning unit 18 is connected to the top 11 of the cylinder. The cleaning unit 18 can be arranged opposite to the first negative pressure device 102. The cleaning unit 18 is used to clean the inside of the feed cylinder 1. The cleaning unit 18 includes a water supply pipe and a spraying device. The water supply pipe is connected to the spraying device, and the other end of the water supply pipe can be connected to a water tank or a cleaning liquid pipe. The spraying device includes a nozzle (or a spray head) and an air pump. The nozzle can be set inside the top 11 of the cylinder. The air pump is connected to the nozzle. The cleaning liquid in the water supply pipe is sprayed into the inside of the feed cylinder 1 through the nozzle and the air pump. The cleaning waste liquid is discharged through the bottom port 12. Finally, the first negative pressure device 102 is used to ventilate the inside of the feed cylinder 1 to accelerate drying. The structure of the nozzle, spray head, air pump, etc. can refer to the existing technology, or existing pneumatic or electric spraying devices can be directly used.

[0046] like Figure 5 As shown, the reaction chamber 20 is the main place for processing materials. The reaction chamber 20 includes a support 21, a cylinder 22, a cover 23, a stirring device, and a rotating device.

[0047] The support 21 adopts a rectangular frame structure to support other components. Its height is greater than that of the cylinder 22, creating a height difference between the support 21 and the cylinder 22, which facilitates various movements of the cylinder 22. The support 21 can be formed by welding frames and needs to have sufficient strength to support other material discharge structures. The support 21 also has a first sub-support 211 and a second sub-support 212, which are arranged opposite each other on both sides of the support 21, near the bottom of the support 21, and also serve to support other components to ensure that the other components are at a suitable height. In other embodiments, the first sub-support 211 and the second sub-support 212 are movably arranged on the support 21 to provide adjustability and allow for adjustment of the appropriate working height. In addition, a baffle 213 is provided inside the support 21. The baffles 213 are symmetrically arranged inside the support 21, with the cylinder 22 located between the baffles 213, and the baffles 213 extend to the bottom of the support 21 to prevent liquid from splashing to both sides when the cylinder 22 rotates to pour out materials, thus avoiding damage.

[0048] The cylinder 22 is the main site for material reaction. It can be a cylindrical structure with its axial direction extending in the direction of gravity. The cylinder 22 is made of metal and can be housed in the support 21. In this embodiment, the cylinder 22 is rotatably mounted on the support 21. The axis of rotation of the cylinder 22 is orthogonal to the direction of gravity. The interior of the cylinder 22 is a cavity 222 for containing materials. The top of the cylinder 22 has an opening 221, which is an open structure and communicates with the cavity 222. Materials usually enter the cavity 222 from the top of the cylinder 22, that is, the materials enter the cavity 222 from the opening 221. When the cylinder 22 remains stationary under the action of gravity, the opening 221 faces upward. The bottom of the cylinder 22 adopts a sealed structure and can be directly designed as a single piece. There is a height difference between the bottom of the cylinder 22 and the bottom of the support 21. When the cylinder 22 rotates, it causes the opening 221 to flip so that the opening 221 can gradually approach the bottom of the support 21, and also avoids other unnecessary interference.

[0049] The cover 23 is located on the upper side of the cylinder 22, also within the support 21, and is used to seal the cylinder 22 so that the material can react safely (spraying the reaction liquid). The cover 23 is movably mounted on the support 21. During the reaction of the material in the cavity 222, the cover 23 is driven to move onto the opening 221 to cover it. A cover driving device 231 is mounted on the support 21. The cover driving device 231 is specifically an electric telescopic rod, or other pneumatic telescopic devices can be used. There are two cover driving devices 231, which are respectively mounted on both sides of the cover 23. The output end of the cover driving device 231 is connected to the cover 23. In use, the two cover driving devices 231 act on the cover 23 simultaneously, so that the cover 23 can move in a balanced manner. When the material needs to be poured out after the reaction is completed, the cover 23 needs to be moved upward so that the cylinder 22 can rotate normally. Furthermore, a retractable input pipe 235 is provided on the top of the cover 23. The input pipe 235 is connected to the cavity 222. The material can enter through the input pipe 235 and pass through the opening 221 to be stored in the cavity 222. The input pipe 235 can be made of a soft material, which can stretch and shape as the cover 23 moves, so as to adapt to the movement function of the cover 23. Preferably, the input pipe 235 is connected to the output cylinder 15 so that the material can be input from the feeding mechanism 10 to the cylinder 22. Furthermore, the cover 23 is equipped with a spraying device 232 and a water spraying device 233. The spraying device 232 is used to spray the reaction liquid (connected to the reaction liquid conduit), and the water spraying device 233 is used to spray the cleaning liquid (connected to a water tank). The spraying device 232 and the water spraying device 233 also have nozzle structures set inside the cover 23, and the liquid is sprayed out by equipment such as an air pump (they can share a common air pipe). In addition, a support rod 234 is also provided inside the cover 23, and the spraying device 232 and the water spraying device 233 are both set on the support rod 234.

[0050] In some embodiments, the cover 23 and the cylinder 22 may be provided with mutually cooperating positioning structures (not shown), such as a positioning post structure on the cover 23 and a positioning hole structure on the cylinder 22. When the cover 23 moves downward, the positioning post and the positioning hole cooperate to allow the cover 23 to cover the preset position, thus achieving positioning movement of the cover 23 and avoiding misalignment that would result in incomplete coverage. Of course, the positioning post and the positioning hole can be interchanged. Furthermore, partial structures can extend from the edges of the cover 23 and the cylinder 22, and the positioning post and the positioning hole can be correspondingly provided on the edges of the cover 23 and the cylinder 22.

[0051] In some embodiments, such as Figure 7As shown, a dehumidifier 236 is provided on the cover 23. The dehumidifier 236 is preferably a ducted dehumidifier. It removes moisture by lowering the air temperature through an evaporator and then heats the air through a condenser to prevent excessively low temperatures. This type of dehumidifier is typically integrated with an HVAC system, providing more precise temperature and humidity control. Since the material input into the cavity 222 itself has a certain temperature, water vapor easily forms within the sealed cavity 222. Therefore, proper dehumidification is necessary to ensure the quality of the spray reaction liquid. Furthermore, the dehumidifier 236 can also appropriately regulate the temperature, typically operating between 20°C and 200°C.

[0052] like Figure 5 As shown, the stirring device is used to uniformly stir the material in the cavity 222. The rotation axis of the stirring device is the same as the rotation axis of the cylinder 22. The stirring device includes a stirring shaft 241 and a first drive device 242. The stirring shaft 241 passes through the cylinder 22 horizontally and extends into the cavity 222. The bracket 21 rotatably supports the stirring shaft 241. The stirring shaft 241 is provided with multiple connecting rods 243 and multiple stirring elements 244. The connecting rods 243 are fixedly connected to the stirring shaft 241 by screws or bolts. The stirring elements 244 are connected to the ends of the connecting rods 243. Each connecting rod 243 has at least one stirring element 244. The multiple connecting rods 243 are evenly spaced along the axial direction of the stirring shaft 241. In this embodiment, the axial directions of two adjacent connecting rods 243 are orthogonal to each other, or they can be arranged in a crisscrossing manner to improve the uniformity of stirring. In other embodiments, multiple stirring elements 244 can be provided in each connecting rod 243 so that the material can be fully stirred by the stirring elements 244. When the stirring element 244 is driven to rotate, it can circulate to the bottom of the cavity 222 to fully stir the material located at the bottom of the cavity 222. In other embodiments, the stirring element 244 located at the end of the connecting rod 243 can be made of an elastic material to avoid hard contact with the bottom of the cavity 222. The first driving device 242 is preferably a motor, and the output end of the first driving device 242 is driven to connect to the stirring shaft 241, so that the first driving device 242 can drive the stirring shaft 241 to rotate. The first driving device 242 is mounted on the first bracket 211. In use, the first driving device 242 drives the stirring shaft 241 to rotate, thereby driving the connecting rod 243 and the stirring element 244 to rotate, so that the connecting rod 243 and the stirring element 244 can fully stir the material. Because the material is prone to clumping after spraying the reaction liquid, it is necessary to ensure the looseness of the material during spraying to improve the effectiveness of the insulating coating layer required for the material to form. Therefore, the stirring device is mainly used to crush the material, prevent the material from clumping, and improve the quality of the material output. In addition, the axis of the stirring shaft 241 extends in the horizontal direction, and the design structure of the stirring device is not likely to cause interference when the material is falling.

[0053] The rotating device is used to drive the cylinder 22 to rotate, such as Figure 6 As shown, the rotating device causes the cylinder 22 to tilt or flip along a preset rotation axis. The rotating device includes a bushing 251, a second drive device 252, a connecting shaft 253, and a drive rod 254. The second drive device 252 is specifically a motor, which is mounted on the second bracket 212. The output end of the second drive device 252 is connected to the bushing 251 for transmission. The bushing 251 is rotatably mounted on the bracket 21. Of course, the bushing 251 can be mounted on the bracket 21 by bearings. There are two bushings 251 symmetrically arranged. The stirring shaft 241 is sleeved in the bushing 251. Similarly, a bearing adapted to the stirring shaft 241 is provided in the bushing 251 so that the stirring shaft 241 can be supported and rotated by the bushing 251. One end of the bushing 251 is fixedly connected to the cylinder 22 by screws or bolts. When the second drive device 252 drives the bushing 251, it can drive the cylinder 22 to rotate. The connecting shaft 253 is sleeved on the other end of the bushing 251. The drive rod 254 adopts a straight rod structure and passes through both the bushing 251 and the connecting shaft 253 through a hole. The drive rod 254 is connected to the output end of the second drive device 252, that is, the power of the second drive device 252 is transmitted to the bushing 251 through the drive rod 254. In use, the second drive device 252 starts and outputs power to drive the drive rod 254 to rotate. The drive rod 254 drives the bushing 251 to rotate, causing the cylinder 22 to rotate. Thus, the cylinder 22 can drive the opening 221 to flip, allowing the material in the cavity 222 to be discharged. Therefore, the rotation axis of the stirring device and the rotation axis of the rotating device are the same, both extending in the horizontal direction. That is, the stirring device and the rotating device have a common rotation axis acting on the cylinder 22.

[0054] Furthermore, such as Figure 7 As shown, a temporary storage tank 26 and a cleaning fluid discharge tank 27 are provided on both sides below the cylinder 22. The temporary storage tank 26 and the cleaning fluid discharge tank 27 are arranged opposite each other on both sides of the cylinder 22 with the stirring shaft 241 as the axis of symmetry. The temporary storage tank 26 can be used to temporarily store the material discharged from the cylinder 22. The output end of the temporary storage tank 26 can be used as the output end of the reaction chamber 20. An open and close switch structure can be installed in the temporary storage tank 26. The other end of the temporary storage tank 26 is connected to the conduit of the next process, and the material stored in the temporary storage tank 26 can be directly sent to the next process. The cleaning fluid discharge tank 27 is used to receive the cleaning waste liquid in the cylinder 22. The bottom of the cleaning fluid discharge tank 27 is provided with an outlet, and the cleaning waste liquid can be discharged through the conduit and scientifically treated. During use, the material after being sprayed with the reaction liquid is discharged from the opening 221 and falls into the temporary storage tank 26. After the cavity 222 is emptied, when the cylinder 22 needs to be cleaned, the water spraying device 233 sprays the cleaning liquid into the cavity 222 and then uses the stirring device to stir and clean it. Finally, the cleaned material is discharged from the opening 221 to the cleaning liquid discharge tank 27 and scientifically treated.

[0055] Working principle: When the material enters the cavity 222 through the opening 221 from the input pipe 235, the spraying device 232 is started to spray the reaction liquid onto the material. At the same time, the stirring device is started to drive the stirring element 244 and the connecting rod 243 to rotate, so as to stir the material and prevent it from clumping. After the spraying and stirring work is completed, the spraying device 232 and the stirring device are stopped, the cover 23 is opened, that is, the cover 23 is controlled to move upward, and then the rotating device is started to drive the cylinder 22 to rotate, so as to drive the opening 221 to flip (rotate counterclockwise), so that the material that has been sprayed with the reaction liquid is discharged from the opening 221. The material enters the temporary storage tank 26 or directly enters the next process. The rotating device controls the cylinder 22 to reset, and the cavity 222 is cleaned by controlling the water spraying device 233 to spray the cleaning liquid. Then the opening 221 is flipped to discharge the cleaning waste liquid to the cleaning liquid discharge tank 27.

[0056] like Figure 8 As shown, the drying system 30 is mainly used for heating and drying materials. The drying system 30 includes a drying chamber 31, a third negative pressure device 32, a heater 33, and a fourth negative pressure device 34.

[0057] The drying chamber 31 is a metal container with a hollow internal structure. Its external shape is not limited and can be designed according to actual needs, such as rectangular or cylindrical. The hollow structure inside the drying chamber 31 is mainly used for drying the input materials. The drying chamber 31 is equipped with a first feed inlet 311, a conveying inlet 312, an air inlet 313, and an exhaust outlet 314, all of which can communicate with the interior of the drying chamber 31. The first feed inlet 311 and the exhaust outlet 314 are located at one end in direction B, which is the second direction. The first feed inlet 311 and the exhaust outlet 314 are located at the top (upper side) of the drying chamber 31. In this embodiment, the first feed inlet 311 and the exhaust outlet 314 are located on the side wall of the top of the drying chamber 31. The conveying inlet 312 and the air inlet 313 are located at one end in direction A, which is the first direction. That is, the conveying inlet 312 and the air inlet 313 are located at the bottom (lower side) of the drying chamber 31, and are on the same side in the left-right direction. In this embodiment, the air inlet 313 is located on the side wall of the bottom of the drying chamber 31. It can be seen that the first feed inlet 311 and the conveying inlet 312 are arranged opposite to each other and connected in direction A, so that the material can be output to the conveying inlet 312 by gravity after entering from the first feed inlet 311. In this embodiment, the conveying inlet 312 can be used as the output end of the drying system 30. Specifically, the first feed inlet 311 can be connected to the output end of the temporary storage box 26 through a conduit, or the material can be attracted into the drying chamber 31 by negative pressure. The air inlet 313 and the exhaust outlet 314 are arranged opposite to each other and connected in the B direction. In the left-right direction, the first feed inlet 311 and the exhaust outlet 314 are arranged opposite to each other, and the first feed inlet 311 and the air inlet 313 are located on the same side. The air inlet 313 is used to input hot airflow, which enters from the air inlet 313 and exits from the exhaust outlet 314, allowing the hot airflow to quickly fill the entire interior of the drying chamber 31. In addition, auxiliary control components such as temperature sensors, control switches, and electrical boxes can also be installed on the drying chamber 31.

[0058] Furthermore, such as Figure 9 As shown, a guide section 315 is provided inside the drying chamber 31. The guide section 315 can adopt a funnel-shaped structure. The guide section 315 is close to the bottom of the drying chamber 31. That is, the inclined structure guides the material falling from the first feed port 311 to the feed port 312. The upper edge of the guide section 315 is connected to the inner wall of the drying chamber 31, and the lower side of the guide section 315 is connected to the feed port 312. Of course, the guide section 315 can also be integrally formed inside the drying chamber 31.

[0059] In other embodiments, since the air inlet 313 is close to the bottom of the drying chamber 31, material may enter the air inlet 313. Therefore, a baffle (not shown) is provided inside the air inlet 313. The baffle is made of metal and is used to block material from entering the air inlet 313 while allowing the hot airflow to pass through normally.

[0060] The third negative pressure device 32 is specifically a negative pressure fan. The input end of the third negative pressure device 32 is connected to the exhaust port 314, and the output end of the third negative pressure device 32 can be discharged to the outside through a duct structure. It is used to discharge the hot airflow output from the drying chamber 31. The third negative pressure device 32 is used to drive the hot airflow into the air inlet 313 and out through the exhaust port 314, thereby driving the movement of the hot airflow and guiding its direction. The third negative pressure device 32 is located on the outside of the drying chamber 31 and can be installed using a support frame.

[0061] like Figure 1 As shown, heater 33 is used to provide a heat source for the material to be dried, that is, it is the main source of hot air flow. Heater 33 can refer to existing technologies, such as resistance heater 33, hot air heater 33, gas heater 33, etc. Hot air heater 33 includes direct and indirect hot air furnaces. Its principle is to directly burn fuel (such as natural gas, liquefied petroleum gas, light oil, etc.) and form high-temperature hot air through high purification treatment, which directly contacts the material for heating, drying or baking. Alternatively, it can use steam, heat transfer oil or flue gas as a heat carrier and heat the air through a heat exchanger. It can also use an electric heating hot air generator to heat the air through resistance wire or other electric heating elements, directly converting electrical energy into heat energy.

[0062] The fourth negative pressure device 34 is specifically a negative pressure fan. The input end of the fourth negative pressure device 34 is connected to the output of the heater 33, and the output end of the fourth negative pressure device 34 is connected to the air inlet 313. A heat-resistant conduit can be used for the connection. The fourth negative pressure device 34 is used to accelerate and drive the hot airflow generated by the heater 33 to the air inlet 313 so that it can quickly enter the drying chamber 31.

[0063] Working principle: such as Figure 9As shown, after the heater 33 is started, the fourth negative pressure device 34 drives the hot airflow from the air inlet 313 into the drying chamber 31. The third negative pressure device 32 is started to output the hot airflow along the exhaust port 314, so that the hot airflow can quickly fill and continuously renew the flow in the drying chamber 31. At this time, the hot airflow moves along direction B, and the material enters from the first feed port 311 and moves along direction A by its own weight and is discharged from the feed port 312. After the material enters, the hot airflow directly acts on the material. Since the material and the hot airflow move in opposite directions, that is, the material and the hot airflow move towards each other, the drying effect of the hot airflow on the material is more obvious. The hot airflow can flow quickly along the gap between adjacent materials, and the drying effect on the surface of the material is more uniform. Of course, the direction of the hot airflow and the direction of the material can be opposite, as long as the part of the hot airflow is opposite to the part of the material. On the other hand, the hot airflow can also generate a certain resistance to the material, which can increase the drying time to a certain extent. More importantly, the effect of the hot airflow surrounding the material when the material is moving is more obvious.

[0064] In some embodiments, such as Figure 10 As shown, the drying system 30 for material reaction also includes a stirring device for stirring and drying the material after it enters the drying chamber 31. The stirring device includes a third drive device 351, a stirring shaft 352, and multiple stirring rods 353. The third drive device 351 is specifically a motor, which is located on the outside of the drying chamber 31. The output end of the third drive device 351 is connected to the stirring shaft 352 for driving the stirring shaft 352 to rotate. The stirring shaft 352 and the stirring rods 353 are both located inside the drying chamber 31, and the multiple stirring rods 353 move along the stirring shaft 352. With the circumferential arrangement of 2, the axial heights of adjacent stirring rods 353 on the stirring shaft 352 are different. Therefore, when the third driving device 351 drives the stirring shaft 352 to rotate, the stirring shaft 352 drives the stirring rods 353 to rotate in the drying chamber 31 so as to stir the material. The rotation of the stirring rods 353 can stir and disperse the material, making the drying effect of the material more obvious and preventing the material from clumping before entering the drying chamber 31. On the other hand, the stirring device can also drive the material output in the drying chamber 31 to avoid accumulation in the drying chamber 31.

[0065] In some embodiments, the feed inlet 312 is connected to a feed pipe 37, which has a tubular structure and is fixedly connected to the bottom of the feed inlet 312 to prevent material leakage. Normally, the other end of the feed pipe 37 is connected to the equipment of the next process so that the dried material can directly enter the next processing step and avoid contact with external dust. That is, the feed pipe 37 can be used as the output end of the drying system 30. A metering device is provided on the feed pipe 37 for metering the material to the equipment of the next process. The metering device includes a fourth drive device 371 and a feed blade (not shown). The fourth drive device 371 is disposed on the feed pipe 37, and the feed blade is disposed inside the feed pipe 37. The output end of the fourth drive device 371 is drivenly connected to the feed blade to drive the feed blade to rotate. The feed blade has multiple evenly distributed fan blade structures. When the feed blade stops rotating, the output end of the feed pipe 37 is closed, thereby controlling the amount of material output from the drying chamber 31 and improving the automation level of the drying chamber 31.

[0066] like Figure 11 As shown, the screener 40 is mainly used for screening and outputting materials. The screener 40 includes a screening device 41, a fifth negative pressure device 42, and a cooling device 43.

[0067] like Figure 12As shown, the screening device 41 is used to screen materials. The screening device includes a screen frame 411 and a vibration device 412. The shape of the screen frame 411 is not limited and can be rectangular, cylindrical, etc. It has a hollow structure inside, allowing materials to enter the screen frame 411 for screening. The screen frame 411 has a second feed inlet 413, a discharge outlet 414, an air inlet 415, and an exhaust outlet 416. In this embodiment, the length direction of the screen frame 411 is the left-right direction (orthogonal to the direction of gravity). The left-right direction includes the C direction (i.e., the third direction) and the D direction (i.e., the fourth direction). The C direction and the D direction are opposite to each other. The second feed inlet 413 is located on the screen frame 411. At the top of 11, the second feed port 413 is connected to the conveying pipe 37 and is used to input the dried material. The second feed port 413 is closer to the end of the screen frame 411 pointing in the D direction (right side). The discharge port 414 is used to output the screened material. The discharge port 414 is set opposite to the second feed port 413 in the length direction and is closer to the end of the screen frame 411 pointing in the C direction (left side). In the gravity direction, the discharge port 414 is set opposite to the second feed port 413, that is, the discharge port 414 is set at the bottom of the screen frame 411. The material can be output from the discharge port 414 by its own weight. At least one discharge port 414 is provided. An air inlet 415 is located at the bottom of the screen frame 411 and is used to input cold airflow. In the D direction, the air inlet 415 and the discharge port 414 are located on the same side. Of course, the air inlet 415 and the discharge port 414 can also be located on the side wall near the bottom of the screen frame 411. Compared with the discharge port 414, the air inlet 415 is further away from the second feed inlet 413, that is, the air inlet 415 is closer to the left side wall of the screen frame 411. The exhaust port 416 is connected to the air inlet 415 and is used to output the cold airflow after exchanging with the air inside the screen frame 411. The exhaust port 416 is located at the bottom of the screen frame 411. The top of the frame 411 is located on the same side as the second feed inlet 413 in the length direction. Of course, the exhaust port 416 and the second feed inlet 413 can also be located on the side near the top of the screen frame 411. Compared with the second feed inlet 413, the exhaust port 416 is closer to the right side of the screen frame 411. It can be seen that the second feed inlet 413 and the discharge port 414 are located between the air inlet 415 and the exhaust port 416. In the screen frame 411, the movement path of the cold airflow includes the movement path of the material, so as to make full use of the cold airflow and improve the cooling effect of the material.

[0068] Furthermore, in direction C, a baffle 417 is provided between the air inlet 415 and the discharge port 414. The baffle 417 is used to block material from entering the air inlet 415, preventing blockage. In other configurations, the baffle 417 can be omitted. For example, the air inlet 415 and the discharge port 414 can be located on the left side wall of the screen frame 411, and the exhaust port 416 and the second feed port 413 can be located on the right side wall of the screen frame 411. The air inlet 415 is located above the discharge port 414, and the exhaust port 416 is located below the second feed port 413, to prevent material from interfering with the airflow. Preferably, the baffle 417 is inclined between the air inlet 415 and the discharge port 414 to guide the cold airflow.

[0069] The screen frame 411 contains a screen 418 with apertures for screening materials. The screen 418 can be arranged in single, double, or multiple layers within the screen frame 411; this embodiment uses a single layer as an example. The screen 418 is fixed to the inner wall of the screen frame 411. In the length direction, the screen 418 is not completely sealed to the inner wall of the screen frame 411, allowing materials with larger diameters to pass through from both sides. The vibration device 412 is specifically a vibrator, which can be a commonly used industrial vibrator, referencing existing technology. The vibration device 412 is installed on the screen frame 411, generally near the screen 418, to more effectively act on the screen 418, generating vibrational force to be transmitted to it. Materials agglomerated on the screen 418 are separated by vibration, while smaller diameter materials can pass directly through the screen 418.

[0070] Furthermore, a guide plate 419 is also provided inside the screen frame 411. The guide plate 419 is inclinedly connected to the inner wall of the screen frame 411 and is located below the screen 418. It is used to guide the separated material to the discharge port 414. The guide plate 419 has an upstream side and a downstream side. The upstream side is closer to the screen 418, and the downstream side is connected to or close to the discharge port 414 so that when the material falls to the guide plate 419 under its own weight, it can be guided to the discharge port 414 for output.

[0071] Furthermore, a base 441 and an elastic element 442 are provided at the bottom of the screen frame 411. The number of bases 441 and elastic elements 442 are corresponding. The base 441 is used to support the screen frame 411, and the elastic element 442 is preferably a spring. The elastic element 442 abuts between the base 441 and the screen frame 411 to reduce the overall vibration of the equipment.

[0072] The cooling device 43 is specifically a cooler, which is a cooling device used in industry that can generate cold airflow. For example, it is an air cooler or chiller that works by circulating refrigerant and using a fan to lower the air temperature. Some models also have air purification and sterilization functions. Alternatively, a low-temperature air cooler can be used, specifically designed for applications requiring even lower temperatures. It uses efficient refrigeration technology to achieve rapid cooling and is suitable for industrial processes requiring rapid cooling, such as quick-freezing of food and pharmaceutical products. Industrial chillers can also be used; please refer to existing technologies for details. The cooling device 43 primarily provides cold airflow to the air inlet 415, and the output end of the cooling device 43 is directly or indirectly connected to the air inlet 415.

[0073] The fifth negative pressure device 42 is specifically a negative pressure fan. The input end of the fifth negative pressure device 42 is connected to the output end of the cooling device 43, and the output end of the fifth negative pressure device 42 is connected to the air inlet 415, so that the air inlet 415 is connected to the output end of the cooling device 43 through the fifth negative pressure device 42. The fifth negative pressure device 42 is mainly used to further drive the cold airflow generated by the cooling device 43 into the screen frame 411, so that the cold airflow can quickly fill the interior of the screen frame 411. Of course, considering the cold airflow transmission distance, the output end of the fifth negative pressure device 42 and the air inlet 415 can also be connected by a conduit.

[0074] Working principle: such as Figure 12 As shown, the fifth negative pressure device 42 and the cooling device 43 are activated, allowing the cold airflow to quickly enter the screen frame 411. Then, the vibration device 412 is activated. When the material enters the screen frame 411 from the second feed port 413, the material is separated by the vibrating screen 418. The material moves along the C direction in the screen frame 411 to the discharge port 414. At the same time, the cold airflow is continuously input from the air inlet 415 and moves along the D direction in the screen frame 411 to the exhaust port 416, so as to continuously exchange the air in the screen frame 411. That is, the material and the cold airflow move towards each other in the screen frame 411, or the directions of the material and the cold airflow in the screen frame 411 are opposite (or they can be cross-opposite), so that the material is cooled and screened at the same time. Finally, it is guided to the discharge port 414 for output through the guide plate 419. Therefore, the temperature of the output material is lower than that before it entered the screen frame 411, and the simultaneous cooling and screening is conducive to improving the efficiency of material output.

[0075] In some embodiments, such as Figure 13 As shown, the screen 418 is inclinedly arranged inside the screen frame 411. The discharge port 414 and the air inlet 415 are located on the downstream side of the screen 418, and the second feed port 413 and the exhaust port 416 are located on the upstream side of the screen 418. That is, when the material is vibrated and screened on the screen 418, the separated material can fall to the discharge port 414 more quickly, which can further optimize the material output method.

[0076] In some embodiments, two or more layers of screens 418 are provided in the screen frame 411, and the screens 418 are inclinedly arranged in the screen frame 411. In this embodiment, two layers of screens 418 are used as an example. The screens 418 are arranged sequentially along the direction of gravity, and the aperture of the two layers of screens 418 decreases sequentially along the direction of gravity. The downstream side of the screens 418 is an open structure, that is, the material separated on the screens 418 can be output to the lower screens 418 or the guide plate 419 along the downstream side by vibration and its own gravity, so as to achieve screening on both sides or multiple layers, thereby improving the screening accuracy and making the screening effect more obvious. For example, when material enters the upper screen 418, its aperture can separate materials with larger diameters, while smaller clumps of material pass through the upper screen 418 and enter the lower screen 418. The material then falls downstream from the upper screen 418 to the lower screen 418 or the discharge port 414. The clumps are then further separated by the lower screen 418 and finally guided to the discharge port 414 by the guide plate 419 to improve the looseness of the output material. This method is suitable for situations where materials have different diameters.

[0077] In some embodiments, such as Figure 14 As shown, an embodiment structure is provided for screening materials and classifying them according to diameter. At least two discharge ports 414 are provided; this embodiment uses two discharge ports 414 as an example. The discharge ports 414 include discharge port a and discharge port b. The guide plate 419 includes a first guide plate 491 and a second guide plate 492. Both the first guide plate 491 and the second guide plate 492 are inclined. The downstream side of the first guide plate 491 is connected to discharge port a, and the downstream side of the second guide plate 492 is connected to discharge port b. The sidewall of the second guide plate 492 is located on the side of discharge port a near discharge port b, used to prevent material from moving to other parts of the screen frame 411, avoiding incomplete discharge. A screen 418 is positioned above the first guide plate 491 and the second guide plate 492. The screen 418 is inclined within the screen frame 411, and the downstream side of the screen 418 is close to (or connected to) the upstream side of the second guide plate 492. That is, in the direction of gravity, the projection of the downstream side of the screen 418 coincides with the projection of the second guide plate 492. This allows material separated on the screen 418 to fall along the screen 418 to the second guide plate 492 and finally exit from outlet b. Material that passes through the screen 418 falls to the first guide plate 491 and exits from outlet a along the first guide plate 491, thus achieving the separation of materials of different diameters. Of course, two or more layers of screens 418 can be added for further material separation. The number of material outlets 414 is relative to the layers of screens 418 to further separate materials of different diameters and improve the screening accuracy.

[0078] In addition, such as Figure 1 As shown, the material processing reaction drying and sieving machine of this application also has a machine chamber 5. The machine chamber 5 adopts a frame structure and is the outer shape of the material processing reaction drying and sieving machine. The machine chamber 5 surrounds the feeding mechanism 10, reaction chamber 20, drying system 30 and sieving device 40, and is used to protect the internal mechanism. The outer side of the machine chamber 5 is generally equipped with auxiliary devices such as electrical box, operation interface, switch, and controller. The material processing is completed directly inside the machine chamber 5, and the staff only needs to monitor it from outside the machine chamber 5, making the processing and production process safer. The machine chamber 5 is equipped with an exhaust system 51, which is used to depressurize the inside of the machine chamber 5 and discharge excess gas. The exhaust system 51 can be composed of a negative pressure fan and a fan hood. The input end of the negative pressure fan is connected to the inside of the machine chamber 5, and the output end of the negative pressure fan is installed on the outside of the machine chamber 5. The fan hood can be installed on the machine chamber 5 to prevent debris from entering the negative pressure fan and causing blockage, and can also be used to protect the negative pressure fan. If some toxic gases are released inside the engine compartment 5, they can be discharged and scientifically treated through the exhaust system 51. The exhaust system 51 can also depressurize the interior of the engine compartment 5 to avoid pressure imbalance.

[0079] The workflow of the material processing reaction drying and sieving machine in this application is as follows: The raw material is adsorbed by the second negative pressure device 14 and enters the feed cylinder 11 through the feed pipe 13. After dust removal, it is output from the bottom port 12. Guided by the output cylinder 15, the material is fed into the cylinder 22 through the cover 23. The stirring device is started to stir the material, and the spraying device 232 is started to spray the material with reaction liquid. After reacting for a period of time, the rotating device is started to turn the cylinder 22 over, causing the material with uniform reaction liquid to be poured out from the opening 221 into the temporary storage tank 26. The temporary storage tank 26 outputs the material and enters the drying chamber 31 from the first feed port 311. Under the operation of the heater 33, the third negative pressure device 32 and the fourth negative pressure device 34, the material falls to the feed port 312 under its own weight, so that the material can be dried and output through the feed pipe 37. The material enters the screen frame 411 from the second feed port 413. Under the action of the screen 418 and the vibration device 412, the material is screened. At the same time, under the action of the cooling device 43 and the fifth negative pressure device 42, the material can be cooled and output from the discharge port 414. The end of the discharge port 414 can be connected to the unloading car for direct material transfer.
