Description

Technical Field

[0001] The present application relates to the technical field of drying equipment, and in particular to drying equipment for chemical processing. Background Art

[0002] In the process of chemical production, chemical materials need to be dried. The dried materials are easy to transport and store. At the same time, drying can remove moisture from the materials and reduce chemical reactions caused by moisture, such as hydrolysis and oxidation. Rake dryers are usually used in the process of drying chemical materials.

[0003] For example, a Chinese patent document with a publication number of CN221944749U discloses a vacuum rake dryer, comprising a dryer body, a bottom plate and legs are arranged at the lower part of the dryer body, a feed port is arranged at the upper part of the dryer body, a discharge port is arranged at the lower part of the dryer body, heating plates are arranged at the left and right ends of the dryer body, a fixed plate is arranged at the upper part of the bottom plate, a motor is arranged at the upper part of the fixed plate, a rotating shaft is arranged on the right side of the motor, rake teeth are arranged at the upper and lower ends of the rotating shaft, and the rake teeth at the upper end of the rotating shaft and the rake teeth at the lower end are staggered structures. Since the feed pipe is arranged in the middle position of the drying cylinder, the rake teeth on both sides of the feed port need to be inclined and symmetrically arranged. When feeding, the symmetrically arranged rake teeth push the material falling from the feed port to both sides to prevent the material from accumulating in the middle position of the drying cylinder, and then the rotating shaft and the rake teeth are driven to rotate by starting the motor, and the internal material is stirred by the rotation of the rotating shaft and the rake teeth; when discharging, the motor needs to be reversed, and then the rotating rake teeth push the material to move to the middle, and finally discharged from the discharge port.

[0004] In the above-mentioned related technology, the material in the middle of the drying cylinder can be pushed to both sides by rotating the inclined rake teeth. However, after the material is unloaded, the rake teeth still need to rotate to stir the material. During the rotation process, the material will still be pushed to the two ends of the drying cylinder, so that there will be less material in the middle of the drying cylinder and more material at the two ends, resulting in a decrease in the drying efficiency of the materials at both ends. Summary of the invention

[0005] The present application provides a drying device for chemical processing, aiming to solve the problem of decreased material drying efficiency in related technologies.

[0006] The present application provides a drying equipment for chemical processing using the following technical solution: A drying device for chemical processing comprises a frame and a drying cylinder fixed on the frame, a feed pipe is arranged above the drying cylinder, a discharge pipe is arranged below the drying cylinder, a stirring assembly for stirring and conveying materials is arranged in the drying cylinder, the stirring assembly comprises a stirring shaft rotatably connected to the drying cylinder, a plurality of fixed cylinders fixed on the stirring shaft, a stirring rod rotatably connected to the fixed cylinder, and rake teeth fixed on the stirring rod, the rake teeth on both sides of the feed pipe are inclined in opposite directions, a plurality of adjustment assemblies for adjusting the angles of the rake teeth are arranged on the stirring shaft, and the plurality of adjustment assemblies correspond to the plurality of rake teeth in one-to-one correspondence, the adjustment assembly comprises a rotating rod slidably connected to the stirring rod, an arc groove provided on the surface of the rotating rod, and an adjustment block slidably connected in the arc groove, the arc groove on the left side of the feed pipe and the arc groove on the right side are inclined in opposite directions, an adjustment rod is slidably connected to the stirring shaft, and the adjustment block is fixedly mounted on the adjustment rod.

[0007] By adopting the above technical solution, after the material is evenly distributed in the drying cylinder, the adjusting rod is moved to drive the adjusting block to move. Under the action of the arc groove, the adjusting block moves and drives the rotating rod to slide on the stirring rod, and drives the rotating rod and the stirring shaft to rotate on the fixed cylinder. At the same time, the rake tooth angles on both sides of the feed pipe are adjusted so that the angles of the rake teeth and the axis of the stirring shaft are on the same plane. When the stirring shaft drives the rake teeth to stir the material, the material will not move to the two ends. At this time, the material will be spread more evenly in the drying cylinder, thereby reducing the accumulation of materials in the drying cylinder.

[0008] Optionally, one end of the stirring shaft extending out of the drying cylinder is fixed with a mounting sleeve by bolts, and a driving assembly for driving the adjusting rod to slide back and forth on the stirring shaft is provided in the mounting sleeve. The driving assembly includes a driving screw rotatably connected in the mounting sleeve and a driving motor fixed in the mounting sleeve, the output shaft of the driving motor is fixedly connected to the driving screw, and the driving screw is passed through the adjusting rod and is threadedly connected to the adjusting rod.

[0009] By adopting the above technical solution, when the rake tooth angle needs to be adjusted, the adjusting screw is driven by the driving motor to rotate, and then the adjusting screw drives the adjusting rod to move, thereby adjusting the position of the adjusting block.

[0010] Optionally, two cleaning plates are provided in the drying cylinder, and the cleaning plates slide on the stirring shaft along the length direction of the stirring shaft. The cleaning plates are provided with make way grooves for making way for the fixed cylinder, the stirring rod and the rake teeth. The cleaning plates are provided with sealing components for sealing the make way grooves. The drying cylinder is provided with a pushing component for pushing the two cleaning plates to move in opposite directions.

[0011] By adopting the above technical solution, after drying is completed, the stirring shaft stops rotating, and the angle of the rake teeth and the axis of the stirring shaft are in the same plane, and then the two cleaning plates are brought closer to each other by the pushing assembly, which will push the dried material to be discharged from the middle discharge pipe, thereby making the discharge of the dried material more efficient. In addition, since the cleaning plate abuts against the inner wall of the drying cylinder, the inner wall of the drying cylinder can be cleaned during the movement of the cleaning plate, and the residual material on the surface of the fixed cylinder and part of the rake teeth can also be cleaned, which is convenient for subsequent drying of different types of chemical materials.

[0012] Optionally, the sealing assembly includes a first sealing plate and a second sealing plate slidably connected to the cleaning plate, and the cleaning plate is provided with a first push spring and a second push spring, the first push spring is used to push the first sealing plate to move toward the direction close to the second sealing plate, and the second push spring is used to push the second sealing plate to move toward the direction of the first sealing plate.

[0013] By adopting the above technical solution, when the fixing sleeve and the stirring rod are not passed through, the first push spring is used to push the first sealing plate to move toward the second sealing plate, and the second push spring is used to push the second sealing plate to move toward the first sealing plate, so that the first sealing plate and the second sealing plate can seal the give way groove, and then the leakage of material from the give way groove when the material is pushed to move toward the discharge port can be reduced.

[0014] Optionally, the pushing assembly includes a sealing bellows fixed on the cleaning plate, a connecting ring fixed on the inner wall of the drying cylinder and an air pump for inflating air into the connecting ring. A mounting ring is fixedly installed on one end of the sealing bellows away from the cleaning plate. The mounting ring is rotatably connected to the connecting ring and is communicated with the connecting ring.

[0015] By adopting the above technical solution, when the air pump inflates the connecting ring, the gas will enter the mounting ring through the connecting ring, and then enter the sealing bellows. At this time, the cleaning plate will be pushed to slide in the drying cylinder, and then the cleaning plate can be pulled to move in the opposite direction during the air extraction process, so that the sealing bellows is in a compressed state.

[0016] Optionally, a mounting groove is provided on the cleaning plate, the mounting groove is connected to the clearance groove, and the first sealing plate and the second sealing plate are slidably connected in the mounting groove, and the first sealing plate and the second sealing plate are both provided with a sealing component for making the clearance groove and the surface of the cleaning plate flush.

[0017] By adopting the above technical solution, the blocking component makes the surface of the clearance groove and the cleaning plate flush, thereby reducing the material remaining in the installation groove.

[0018] Optionally, the sealing assembly includes a connecting plate slidably connected to the first sealing plate, a first sealing plate and a second sealing plate fixed to the connecting plate, the first sealing plate and the second sealing plate are arranged at both ends of the connecting plate, and the first sealing plate and the second sealing plate are both arranged parallel to and spaced apart from the first sealing plate; a first supporting spring and a second supporting spring are arranged on the connecting plate, one end of the first supporting spring is fixed to the first sealing plate, and the other end is fixed to the first sealing plate, and one end of the second supporting spring is fixed to the second sealing plate, and the other end is fixed to the second sealing plate.

[0019] By adopting the above technical solution, when the cleaning plate moves close to the discharge pipe, the rake teeth will first contact the first sealing plate. At this time, since the first sealing plate can only move along the axial direction of the stirring shaft, the first sealing plate will be pushed to slide on the first sealing plate, so that the first supporting spring is in a stretched state and the second supporting spring is in a compressed state. When the first sealing plate corresponds to the mounting groove, the rake teeth will push the first sealing plate and the second sealing plate to move into the mounting groove at the same time. When the fixed cylinder, the stirring rod and the rake teeth are disengaged from the clearance groove, the first sealing plate and the second sealing plate are reset under the action of the first push spring and the second push spring, and the first sealing plate and the second sealing plate are reset under the action of the first support spring and the second support spring, so as to block the mounting groove and reduce the material from entering the clearance groove.

[0020] Optionally, the first sealing plate and the second sealing plate are provided with guide surfaces, and the rake teeth are provided with push surfaces, and the push surfaces are used to abut against the guide surfaces.

[0021] By adopting the above technical solution, when the cleaning plate moves toward the discharge pipe, the pushing surface and the guide surface abut against each other, and then push the connecting plate to move along the length direction of the stirring shaft. When the first sealing plate and the mounting groove correspond, the pushing surface pushes the two connecting plates away from each other, and the sealing assembly can be moved into the mounting groove.

[0022] In summary, this application has the following beneficial effects: 1. When the adjusting block moves, it will drive the rotating rod to slide on the stirring rod, and drive the rotating rod and the stirring shaft to rotate on the fixed cylinder, so as to adjust the angle of the rake teeth on both sides of the feed pipe at the same time, so that the axes of the rake teeth and the stirring shaft are in the same plane. When the stirring shaft drives the rake teeth to stir the material, the material will not move to the two ends, and the material will be spread more evenly in the drying cylinder.

[0023] 2. After drying is completed, the stirring shaft stops rotating, and the angle of the rake teeth and the axis of the stirring shaft are in the same plane. Then, the two cleaning plates are moved closer to each other through the pushing assembly. At this time, the dried material will be pushed out from the middle discharge pipe, making the discharge of the dried material more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following combination Figure 1-Figure 12 This application is described in further detail.

[0038] The present application embodiment discloses a drying device for chemical processing. Figure 1 and Figure 2 A drying device for chemical processing includes a frame 01 set on the ground and a drying cylinder 02 fixed on the frame 01, the axis of the drying cylinder 02 is set horizontally, a feed pipe 03 is set above the drying cylinder 02, and a discharge pipe 04 is set below the drying cylinder 02, the feed pipe 03 and the discharge pipe 04 are both connected to the inside of the drying cylinder 02, and a stirring component 1 is set in the drying cylinder 02, the stirring component 1 is used to stir the material in the drying cylinder 02, and at the same time, it can also push the material falling from the feed pipe 03 to move to both ends, and can also push the dried material to move in the direction of the discharge pipe 04, and then facilitate the material to be discharged through the discharge pipe 04.

[0039] Reference Figure 1 and Figure 2 The stirring assembly 1 includes a stirring shaft 11 rotatably connected to the drying cylinder 02, a fixed cylinder 12 fixed on the stirring shaft 11, a stirring rod 13 rotatably connected to the fixed cylinder 12, and rake teeth 14 fixed on the stirring rod 13. In the initial state, the rake teeth 14 and the axis of the stirring shaft 11 are set at an angle, and the rake teeth 14 on both sides of the feed pipe 03 are inclined in opposite directions, so that when the stirring shaft 11 rotates forward, the material falling from the feed pipe 03 can be pushed to move to the two ends of the drying cylinder 02 to reduce the accumulation of materials under the feed pipe 03. Then, after the drying is completed, the stirring shaft 11 rotates in the opposite direction to push the material to the position of the discharge pipe 04, so as to facilitate the discharge of the dried material from the discharge pipe 04. There are multiple stirring rods 13 and rake teeth 14 on the stirring shaft 11, which can better stir the material.

[0040] Reference Figures 2 to 5 A plurality of adjustment components 2 are arranged on the stirring shaft 11, and the plurality of adjustment components 2 correspond to the plurality of stirring rods 13 one by one. The adjustment components 2 are used to adjust the angle of the rake teeth 14. When the material completely enters the drying cylinder 02, the adjustment components 2 are used to make the axes of the rake teeth 14 and the stirring shaft 11 in the same plane. Then, when the stirring shaft 11 drives the rake teeth 14 to stir the material, the material will not move to both ends. At this time, the material will be spread more evenly in the drying cylinder 02, and then when the material is dried, the accumulation of the material is avoided, thereby improving the drying efficiency of the material.

[0041] Reference Figures 2 to 5 The adjusting assembly 2 includes a rotating rod 21 slidably connected to the stirring rod 13, an arc groove 22 provided on the surface of the rotating rod 21, and an adjusting block 23 slidably connected in the arc groove 22. An adjusting rod 24 is slidably connected to the stirring shaft 11. The arc groove 22 is arranged along the circumference of the rotating rod 21, and a highest point and a lowest point are formed on the rotating rod 21. A plurality of adjusting blocks 23 are arranged, and a plurality of adjusting blocks 23 correspond to a plurality of rotating rods 21 one by one. The plurality of adjusting blocks 23 are fixed to the adjusting rod 24 by welding. In this embodiment, the arc groove 22 on the left side of the feed pipe 03 and the arc groove 22 on the right side are inclined. The direction is opposite, and then when the adjustment rod 24 is pushed to move, multiple adjustment blocks 23 can be driven to move simultaneously in the horizontal direction. When the adjustment block 23 moves, the rotating rod 21 is driven to slide in the vertical direction. At this time, the rotating rod 21 will slide on the stirring rod 13, and the adjustment block 23 will slide in the arc groove 22. Since the adjustment block 23 can only move horizontally, the rotating rod 21 rotates relative to the adjustment block 23, and the rotating rod 21 and the stirring rod 13 will be driven to rotate on the fixed cylinder 12, thereby adjusting the angle of the rake teeth 14 on both sides of the feed pipe 03 at the same time, reducing the accumulation of materials in the drying cylinder 02. In the initial state, the adjustment block 23 is in the middle position of the arc groove 22, and the rake teeth 14 and the axis of the stirring shaft 11 are on the same plane. Then, when the stirring shaft 11 rotates, it will only stir the material, and will not transport the material to the sides or the middle.

[0042] The adjusting rod 24 moves along the direction of the stirring shaft 11, and during the movement of the adjusting rod 24, the adjusting block 23 is driven to move horizontally. Due to the horizontal movement of the adjusting block 23, under the action of the arc groove 22, the adjusting block 23 drives the rotating rod 21 to slide on the stirring. At the same time, since the arc groove 22 is arranged along the circumference of the rotating rod 21, the rotating rod 21 can also drive the stirring rod 13 to rotate on the fixed cylinder 12, and the position of the rake teeth 14 can be adjusted at this time; in the process of the adjusting rod 24 driving the adjusting block 23 to move to the right, the adjusting block 23 located in the middle position of the arc groove 22 will move to the lowest point of the arc groove 22, and at this time, The rotating rod 21 is driven to move up and down while the stirring rod 13 can also be rotated. When the rotating rod 21 rotates, the stirring rod 13 and the rake teeth 14 fixed on the stirring rod 13 are driven to rotate; in the process of the adjusting rod 24 driving the adjusting block 23 to move to the left, the adjusting block 23 located in the middle position of the arc groove 22 will move toward the highest point of the arc groove 22. At this time, the rotating rod 21 is driven to move up on the stirring rod 13 while the rotating rod 21 can also be rotated. When the rotating rod 21 rotates, the stirring rod 13 and the rake teeth 14 fixed on the stirring rod 13 are driven to rotate, thereby achieving the purpose of adjusting the angle of the rake teeth 14.

[0043] Reference Figures 2 to 5 In order to facilitate the sliding of the rotating rod 21 on the stirring rod 13, a slide groove is opened on the rotating rod 21, and a slider is fixedly installed on the stirring rod 13. The slider is slidably connected in the slide groove, so that when the adjusting block 23 moves, the rotating rod 21 can move on the stirring rod 13, and the stirring rod 13 can also drive the rake teeth 14 to rotate.

[0044] Reference Figures 2 to 5 , one end of the stirring shaft 11 extending out of the drying cylinder 02 is fixedly installed with a mounting sleeve 05 by bolts, and a driving assembly 3 is arranged in the mounting sleeve 05, and the driving assembly 3 is used to drive the adjusting rod 24 to slide back and forth on the stirring shaft 11, so that the position of the adjusting block 23 can be adjusted, and then it is convenient to adjust the angle of the rotating rod 21 and the rake teeth 14; the driving assembly 3 includes a driving screw 31 rotatably connected to the mounting sleeve 05 and a driving motor 32 fixed in the mounting sleeve 05, the output shaft of the driving motor 32 is fixedly connected to the driving screw 31, the driving screw 31 is penetrated on the adjusting rod 24, and is threadedly connected to the adjusting rod 24. When the angle of the rake teeth 14 needs to be adjusted, the driving screw 31 is driven to rotate by the driving motor 32, and then the adjusting rod 24 is driven to move by the driving screw 31, so that the position of the adjusting block 23 can be adjusted.

[0045] Reference Figures 2 to 6Two cleaning plates 4 are arranged in the drying cylinder 02. In the initial state, the two cleaning plates 4 are at both ends of the drying cylinder 02. Then, when it is necessary to clean the raw materials in the drying cylinder 02, the cleaning plates 4 slide along the length direction of the stirring shaft 11; when the stirring shaft 11 rotates, the two cleaning plates 4 are at both ends of the drying cylinder 02, which can drive the cleaning plates 4 to rotate at the same time. The cleaning plates 4 are arranged in an annular structure, and the side surfaces of the cleaning plates 4 abut against the inner wall of the drying cylinder 02; a make way groove 41 for making way for the fixed cylinder 12, the stirring rod 13 and the rake teeth 14 is opened on the cleaning plate 4. Then, when the cleaning plate 4 moves, the fixed cylinder 12 and the stirring rod 13 can be prevented from affecting the movement of the cleaning plate 4. After the drying is completed, the stirring shaft 11 stops rotating, and the axes of the rake teeth 14 and the stirring shaft 11 are made in the same plane, and then the two cleaning plates 4 are made close to each other, at which time the dried material will be pushed to be discharged from the middle discharge pipe 04, so that the efficiency of discharging the dried material is faster. In addition, since the cleaning plate 4 abuts against the inner wall of the drying cylinder 02, the inner wall of the drying cylinder 02 can be cleaned during the movement of the cleaning plate 4, and the residual materials on the surface of the fixed cylinder 12 and a part of the rake teeth 14 can also be cleaned, which is convenient for subsequent drying of different types of chemical materials.

[0046] Reference Figures 5 to 10 A sealing assembly 5 is provided on the cleaning plate 4. When the fixed cylinder 12, the stirring rod 13 and the rake teeth 14 are separated from the make way groove 41, the sealing assembly 5 is used to block the make way groove 41, so that when the cleaning plate 4 moves, the leakage of materials from the make way groove 41 can be reduced, and then when discharging the materials, the materials in the drying cylinder 02 can be discharged more cleanly.

[0047] Reference Figures 4 to 9 The sealing assembly 5 includes a first sealing plate 51 and a second sealing plate 52 which are slidably connected to the cleaning plate 4. The first sealing plate 51 and the second sealing plate 52 have the same structure and are used to block the clearance groove 41. The number of the sealing assembly 5 and the clearance groove 41 in this embodiment is the same, and the number of the clearance groove 41 is the same as the number of the stirring rods 13 arranged along the circumference of the stirring shaft 11. In this embodiment, the number of the clearance grooves 41 is four, and a sealing assembly 5 is arranged in each clearance groove 41. The cleaning plate 4 is provided with a mounting groove 42, which is connected to the clearance groove 41, and the first sealing plate 51 and the second sealing plate 52 are slidably connected in the mounting groove 42.

[0048] Reference Figure 6A first push spring 53 is arranged in the mounting groove 42 on the cleaning plate 4. The first push spring 53 is used to push the first sealing plate 51 to move toward the second sealing plate 52. A second push spring 54 is arranged on the cleaning plate 4. The second push spring 54 is used to push the second sealing plate 52 to move toward the first sealing plate 51. One end of the first push spring 53 is fixed to the cleaning plate 4, and the other end is fixed to the first sealing plate 51. One end of the second push spring 54 is fixed to the cleaning plate 4, and the other end is fixed to the second sealing plate 52.

[0049] When the fixed cylinder 12 and the stirring rod 13 are not passed through, the first sealing plate 51 and the second sealing plate 52 are abutted under the action of the first push spring 53 and the second push spring 54, and the give-way groove 41 is sealed by the abutting first sealing plate 51 and the second sealing plate 52, so that the leakage of the material from the give-way groove 41 when the material is pushed to move toward the discharge pipe 04 can be reduced. When the two cleaning plates 4 approach each other, the rake teeth 14 will push the first sealing plate 51 and the second sealing plate 52 away from each other, and the first push spring 53 and the second push spring 54 are compressed. At this time, the first sealing plate 51 and the second sealing plate 52 slide in the mounting groove 42.

[0050] Reference Figures 4 to 9 In order to reduce the amount of material entering the installation groove 42, a blocking component 6 is provided on the first sealing plate 51. The blocking component 6 is used to block the opening of the installation groove 42. At the same time, when the blocking component 6 is in the make way groove 41, the make way groove 41 can be blocked. At the same time, a blocking component 6 is also provided on the second blocking plate 63. Here, only the blocking component 6 on the first sealing plate 51 is described in detail; the blocking component 6 includes a connecting plate 61 slidably connected to the first sealing plate 51, a first blocking plate 62 and a second blocking plate 63 fixed on the connecting plate 61, the first blocking plate 62 and the second blocking plate 63 are arranged at both ends of the connecting plate 61, and the first blocking plate 62 and the first sealing plate 51 are arranged in parallel and spaced apart, the second blocking plate 63 and the first sealing plate 51 are also arranged in parallel and spaced apart, and the connecting plate 61 and the first blocking plate 62 are arranged vertically.

[0051] Reference Figures 4 to 12 A first supporting spring 64 and a second supporting spring 65 are provided on the connecting plate 61, one end of the first supporting spring 64 is fixed on the first blocking plate 62, and the other end is fixed on the first sealing plate 51, one end of the second supporting spring 65 is fixed on the second blocking plate 63, and the other end is fixed on the second sealing plate 52. Under the action of the first supporting spring 64 and the second supporting spring 65, the first blocking plate 62 is flush with one surface of the cleaning plate 4, and the second blocking plate 63 is flush with the other surface of the cleaning plate 4, thereby reducing the material residue in the mounting groove 42.

[0052] Reference Figures 4 to 12 When the cleaning plate 4 moves close to the discharge pipe 04, the pushing surface 44 on the rake teeth 14 will first abut against the guide surface 43 on the first blocking plate 62. Since the side of the first blocking plate 62 facing away from the connecting plate 61 abuts against the inner wall of the clearance groove 41 (such as Fig. 9 As shown in the figure, the first blocking plate 62, the connecting plate 61 and the second blocking plate 63 cannot move along the axial direction perpendicular to the stirring shaft 11, and then the cleaning plate 4 continues to move, which will push the first blocking plate 62, the connecting plate 61 and the second blocking plate 63 to move along the axial direction of the stirring shaft 11. At this time, the connecting plate 61 will slide on the first sealing plate 51, and then the first blocking plate 62 corresponds to the mounting groove 42, so that the first support spring 64 is in a compressed state and the second support spring 65 is in a stretched state (as shown in the figure). Fig.11 As shown in FIG. 1 , the cleaning plate 4 continues to move, the rake teeth 14 push the two connecting plates 61 on both sides away from each other, the first blocking plate 62 moves into the mounting groove 42, and the second blocking plate 63 moves to the outside of the cleaning plate 4 (as shown in FIG. 1 ). Fig.12 As shown), the clearance groove 41 is opened at this time; during the gradual movement of the cleaning plate 4, the cleaning plate 4 will first abut against the rake teeth 14, and then abut against the fixed cylinder 12 (as shown Figure 8 As shown in the figure), when the clearance groove 41 is fully opened, the fixed cylinder 12, the stirring rod 13 and the rake teeth 14 can pass through the clearance groove 41, and the clearance groove 41 plays a role in making way for the fixed cylinder 12, the stirring rod 13 and the rake teeth 14, and the first push spring 53 and the second push spring 54 are in a compressed state; under the action of the first push spring 53 and the second push spring 54, it is convenient to make the connecting plate 61 abut against the surface of the fixed cylinder 12 and the rake teeth 14, and in the process of the cleaning plate 4 driving the connecting plate 61 to move, the material on a part of the surface of the fixed cylinder 12 and the rake teeth 14 is cleaned.

[0053] When the fixing cylinder 12, the stirring rod 13 and the rake teeth 14 are separated from the clearance groove 41, the first sealing plate 51 and the second sealing plate 52 are reset under the action of the first push spring 53 and the second push spring 54, and the first blocking plate 62 and the second blocking plate 63 are reset under the action of the first support spring 64 and the second support spring 65, and the installation groove 42 is continuously blocked. When the cleaning plate 4 moves in the reverse direction, the rake teeth 14 first contact the second blocking plate 63, and its working principle is the same as that of the forward movement of the cleaning plate 4. Here, the process of the reverse movement of the cleaning plate 4 is not described in detail.

[0054] Reference Figures 4 to 12In order to facilitate the rake teeth 14 to move the first sealing plate 62 and the second sealing plate 63 in opposite directions, guide surfaces 43 are provided on the first sealing plate 62 and the second sealing plate 63, and a pushing surface 44 is provided on the rake teeth 14; when the cleaning plate 4 moves toward the discharge pipe 04, the pushing surface 44 abuts against the guide surface 43, and then pushes the connecting plate 61 to move along the length direction of the stirring shaft 11. When the first sealing plate 62 and the mounting groove 42 correspond, the pushing surface 44 pushes the two connecting plates 61 away from each other. At this time, the sealing assembly 6 can be moved into the mounting groove 42, and the side wall of the mounting groove 42 is clamped in the gap between the second sealing plate 63 and the first sealing plate 51.

[0055] In this embodiment, the thickness of the side wall of the mounting groove 42 is greater than the thickness of the first sealing plate 51, and the side wall of the mounting groove 42 can be clamped in the gap between the second sealing plate 63 and the first sealing plate 51, and then the first sealing plate 62 or the second sealing plate 63 is convenient to move into the mounting groove 42. When the first sealing plate 62 moves into the mounting groove 42, the side wall of the mounting groove 42 is clamped in the gap between the second sealing plate 63 and the first sealing plate 51. At this time, the second sealing plate 63 is on the outside of the cleaning plate 4, and vice versa, the first sealing plate 62 is on the outside of the cleaning plate 4.

[0056] Reference Figures 2 to 4 Two pushing assemblies 7 are provided on the drying cylinder 02, and the two pushing assemblies 7 are used to push the two cleaning plates 4 to move in opposite directions. The pushing assembly 7 includes a sealing bellows 71 fixed on the cleaning plate 4, a connecting ring 72 fixed on the inner wall of the drying cylinder 02 and an air pump (not shown in the figure) used to inflate the connecting ring 72. The air pump can inflate or exhaust air into the connecting ring 72. The air pump is fixed on the drying cylinder 02, and a connecting pipe is installed on the air pump. The connecting pipe is used to communicate with the connecting ring 72. A mounting ring 73 is fixedly installed at one end of the sealing bellows 71 away from the cleaning plate 4, and the mounting ring 73 is rotatably connected to the connecting ring 72, so that the sealing effect of the connecting ring 72 and the mounting ring 73 can still be achieved while the cleaning plate 4 drives the sealing bellows 71 to rotate.

[0057] When the air pump inflates the connecting ring 72 through the connecting pipe, the gas in the connecting ring 72 increases, and the pressure in the connecting ring 72 increases. The gas will enter the mounting ring 73 through the connecting ring 72, and the gas entering the mounting ring 73 will enter the sealing bellows 71, so that the pressure in the sealing bellows 71 increases, and then the increased pressure will push the cleaning plate 4 to slide in the drying cylinder 02, and the sealing bellows 71 will be stretched. Since there are two cleaning plates 4 and two pushing components 7, the two cleaning plates 4 will be close to each other at this time; after the cleaning is completed, the air pump evacuates the gas in the sealing bellows 71, and then the gas in the sealing bellows 71 decreases, and the gas pressure becomes smaller at this time, and then the two cleaning plates 4 can be pulled close to each other during the evacuation process, so that the sealing bellows 71 is in a compressed state, and finally the cleaning plates 4 move to both sides of the drying cylinder 02. In other embodiments, the pushing component 7 can also be set as a pushing cylinder, and the cleaning plate 4 is driven to move by the pushing cylinder. In addition, the air pump in this embodiment can be an electric air pump, which can inflate when rotating forward and exhaust air when rotating reversely. Since the specific working method of driving the air pump belongs to the existing technology, the specific structure and working principle of the electric air pump will not be repeated.

[0058] The implementation principle of a drying device for chemical processing in an embodiment of the present application is as follows: in the initial state, the adjustment block 23 is in the middle position of the arc groove 22, at this time the rake teeth 14 are in an inclined state, and the inclination directions of the rake teeth 14 on both sides of the feed pipe 03 are symmetrically arranged, then the stirring shaft 11 rotates to drive the rake teeth 14 to rotate, and the materials falling from the feed pipe 03 are transported to both sides, so that the materials are more evenly distributed in the drying cylinder 02, and then the adjustment block 23 is driven to move by the adjustment rod 24, and the angles of the rotating rod 21, the stirring rod 13 and the rake teeth 14 are adjusted, so that the angles of the rake teeth 14 on both sides of the feed pipe 03 are the same, and the axes of the rake teeth 14 and the stirring shaft 11 are on the same plane, at this time, when the stirring shaft 11 drives the rake teeth 14 to rotate, it will only stir the materials in the drying cylinder 02, and will not push the materials to move; after the material is dried, the angle of the rake teeth 14 is reset, and then the stirring shaft 11 rotates in the opposite direction to push the materials to move in the direction of the discharge pipe 04, so as to facilitate the discharge of the dried materials from the discharge pipe 04.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
