[0002] Zirconia generally refers to zirconium dioxide, which is the main oxide of zirconium. It is usually white, odorless and tasteless crystals and is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. When zirconia is sintered, a lot of sintering waste is generated. The traditional way to deal with the waste is to directly transfer it to a fixed location and discard it, which results in a waste of resources.

[0003] To solve the above problems, a Chinese patent with publication number CN218189889U discloses a zirconia sintering waste recycling and crushing device, including two support plates, a box body is provided on the top of the support plate, two crushing rollers are rotated inside the box body, a double-shaft motor is fixedly connected to the outer wall of the box body, and one end of the output shaft of the double-shaft motor is fixedly connected to the crushing roller, a feed hopper is provided above the crushing roller, a rolling seat fixedly connected to the inner wall of the box body is provided below the crushing roller, positioning plates are provided on both sides of the top of the rolling seat, a rotating shaft is provided inside the positioning plate, a rolling roller is provided on the external fixed sleeve of the rotating shaft, and a transmission assembly is provided between the double-shaft motor and the rotating shaft. This patent can recycle and reprocess waste materials for reuse, effectively avoiding waste of resources and saving costs.

[0004] The following problems existed during the actual use of the above patent: after two crushing processes, the waste materials were collected on the screen, and the waste particles were screened through the screen, and the waste particles of qualified size were screened out for recycling and reuse, while the waste particles of unqualified size were retained on the surface of the screen, that is, there was a problem of uneven crushing; for the waste particles of unqualified size, the staff were required to collect them first and then transfer them to the crushing device for re-crushing, which increased the workload of the staff and reduced the work efficiency. Summary of the invention

[0005] The present invention aims to provide a waste slag recovery device for zirconium dioxide production, so as to solve the problem of uneven crushing of waste materials by existing recovery devices.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a waste slag recovery device for zirconium dioxide production, comprising a box body and two crushing rollers, the box body is provided with a feed port and a discharge port, a partition is provided in the box body, and the bottom of the partition is located above the bottom of the box body; a rotating shaft is rotatably connected to the partition, and the two crushing rollers are coaxially connected to the rotating shaft, and the two crushing rollers are respectively located on both sides of the partition; an adjustment mechanism is provided on both sides of the partition, and the adjustment mechanism includes a first vertical groove, a second vertical groove, and an elliptical block coaxially connected to the rotating shaft, the first vertical groove is located above the second vertical groove, a movable plate is slidably connected in the first vertical groove, a first spring is provided between the movable plate and the first vertical groove, and a discharge port is provided on the movable plate; a mesh plate is slidably connected in the second vertical groove, and a second spring is provided between the mesh plate and the second vertical groove; the two ends of the elliptical block are respectively against the movable plate and the mesh plate; it also includes a driving mechanism for driving the rotating shaft to rotate and an introduction mechanism for intermittently introducing waste slag from the feed port to the discharge port.

[0007] The principles and advantages of this solution are:

[0008] 1. In this scheme, the waste slag is moved between the movable plate and the mesh plate through the feed port and the discharge port; the rotating shaft drives the elliptical block and the crushing roller to rotate, and when the two long-axis ends of the elliptical block respectively abut against the movable plate and the mesh plate, the movable plate moves upward and the mesh plate moves downward, so that the movable plate and the mesh plate are separated, and the first spring and the second spring are compressed; when the two short-axis ends of the elliptical block respectively abut against the movable plate and the mesh plate, the movable plate moves in the opposite direction under the action of the first spring, and the mesh plate moves in the opposite direction under the action of the second spring, so that the movable plate and the mesh plate are close to each other; therefore, the movable plate and the mesh plate continue to approach and move away from each other, so that the waste slag can be pushed close to the crushing roller, and it can be crushed by the rotating crushing roller, and the crushed particles can be screened by the mesh plate to ensure that the waste slag can be crushed into waste slag particles of qualified size, that is, the uniform crushing of the waste slag can be guaranteed, and the utilization rate of waste slag recovery can be guaranteed.

[0009] 2. This solution can intermittently introduce the waste slag into the discharge port through the feed port through the introduction mechanism, that is, a certain amount of waste slag can be introduced between the movable plate and the mesh plate each time, so as to better crush the waste slag and make the crushing effect more uniform.

[0010] 3. This solution uses the screen to make the waste slag particles of uniform size, eliminating the need for manual screening of unqualified waste slag particles, and reducing the process of manually collecting and transferring unqualified waste slag particles for re-crushing, thereby shortening the processing process and improving work efficiency.

[0011] Furthermore, the partition is located in the middle of the feed port; the introduction mechanism includes inclined grooves on both sides of the inner wall of the box body and a transverse groove on the top of the movable plate, the spacing between the two inclined grooves gradually decreases from top to bottom, and an auxiliary block is slidably connected in the inclined groove; a baffle for sealing the feed port is slidably connected in the transverse groove, the baffle is in friction contact with the top of the movable plate, and the auxiliary block is fixed to the baffle.

[0012] Through the above arrangement, the waste residue is divided into two parts by the partition and moves to the two sides of the partition respectively, so that the waste residue falls to the top of the movable plate.

[0013] When the movable plate moves upward, the movable plate drives the baffle plate to move upward, and at the same time, the baffle plate also moves laterally along the path of the inclined groove through the auxiliary block, that is, the two baffle plates move away from each other, so that the shielding effect of the baffle plate on the discharge port disappears, and the waste residue on the top of the movable plate moves through the discharge port to between the movable plate and the mesh plate; when the movable plate moves downward, the movable plate drives the baffle plate to move downward, and at the same time, the baffle plate also moves laterally in the opposite direction along the path of the inclined groove through the auxiliary block, that is, the two baffle plates move close to each other, so that the baffle plate blocks the discharge port, and thus prevents the waste residue on the top of the movable plate from passing through the discharge port and moving between the movable plate and the mesh plate; therefore, intermittent and quantitative discharge of waste residue can be achieved.

[0014] Furthermore, a vertical plate is provided at one end of the baffle plate close to the partition plate, and the distance between the two vertical plates is greater than the width of the feed port.

[0015] Through the above arrangement, when the waste slag moves to the top of the movable plate, the waste slag on one side of the partition is located between the partition and the vertical plate, which can achieve the effect of temporary centralized storage and prevent the waste slag from scattering everywhere so that it can all pass through the discharge port.

[0016] Furthermore, side grooves are provided on the inner walls on both sides of the box body, and cylindrical blocks are coaxially connected at both ends of the rotating shaft. The cylindrical blocks are located in the side grooves and can rotate in the side grooves; curved grooves are provided on the side walls of the cylindrical blocks, and linkage blocks are slidably connected in the curved grooves; sliding grooves are transversely provided on both sides of the inner wall of the box body, and push blocks are slidably connected in the sliding grooves, and the push blocks are located between the movable plate and the mesh plate, and the end of the linkage block away from the curved groove is fixedly connected to the push block; a transverse hole is provided on the push block, and the diameter of the rotating shaft is smaller than the diameter of the transverse hole.

[0017] Through the above arrangement, during the rotation of the shaft, the rotation will also drive the cylindrical block to rotate, and the push block can move back and forth laterally along the path of the curved groove through the linkage block, and then the push block can push the waste slag between the movable plate and the mesh plate to move in the direction of the partition, so that all the waste slag can be crushed and processed by the crushing roller, thereby improving the utilization rate of waste slag recovery.

[0018] Furthermore, guide grooves are vertically provided on both sides of the push block, and a lifting block is slidably connected in the guide groove. A third spring is provided between the lifting block and the guide groove, and the end of the lifting block away from the guide groove is rotatably connected to a guide wheel; the guide wheel on one lifting block is against the movable plate, and the guide wheel on the other lifting block is against the mesh plate.

[0019] Through the above arrangement, during the lateral reciprocating motion of the push block, the push block will also drive the lifting block to move synchronously, and the third spring changes its shape as the distance between the movable plate and the mesh plate changes; that is, the height of the push block is extended by the lifting block, and the range of action of the push block on the waste slag is expanded, so that all the waste slag between the movable plate and the mesh plate can be pushed to move; in addition, by replacing the lifting block with the guide wheel to contact the movable plate and the mesh plate, the friction force can be reduced, making the lateral movement of the push block and the lifting block smoother.

[0020] Furthermore, both sides of the inner wall of the box body are transversely provided with wall grooves, the wall grooves are located below the mesh plate, and wall blocks are slidably connected in the wall grooves; a number of through holes and a number of cleaning layers are equidistantly provided on the wall block along the length direction of the wall block, and the cleaning layer is located between two adjacent through holes; the cleaning layer includes a number of bristles for cleaning the mesh plate, and the bristles are fixedly connected to the top of the wall block; and it also includes an adjustment mechanism that drives the wall block to reciprocate horizontally as the mesh plate reciprocates vertically.

[0021] Through the above arrangement, during the vertical reciprocating motion of the mesh plate, the adjusting mechanism can drive the wall block to move horizontally, and the wall block drives the bristles to move synchronously, so that the bristles continuously enter and exit the mesh plate, thereby cleaning the mesh plate and avoiding clogging of the mesh plate; the waste particles passing through the mesh plate can fall downward through the through holes.

[0022] Furthermore, the adjustment mechanism includes a side groove opened on the side wall of the box body, and a first rack fixed to the bottom of the wall block. The end of the mesh plate away from the partition can move vertically in the side groove, and a second rack is fixed to the bottom of the end of the mesh plate away from the partition. A circular shaft is rotatably connected in the side groove, and a first gear and a second gear are coaxially connected on the circular shaft. The first gear is meshed with the first rack, and the second gear is meshed with the second rack. The movement direction of the first rack is perpendicular to the movement direction of the second rack.

[0023] Through the above arrangement, when the mesh plate moves downward, the mesh plate drives the second rack to move downward, the second rack meshes with the second gear to drive the circular shaft to rotate, the circular shaft drives the first gear to rotate, the first gear meshes with the first rack to drive the first rack to move away from the partition; when the mesh plate moves upward, the mesh plate drives the second rack to move upward, the second rack meshes with the second gear to drive the circular shaft to rotate in the opposite direction, the circular shaft drives the first gear to rotate in the opposite direction, the first gear meshes with the first rack to drive the first rack to move in the direction of the partition; therefore, the first rack can realize transverse reciprocating motion, and the first rack drives the wall block to move transversely.

[0024] Furthermore, water tanks are provided on the outer walls of both sides of the box body; a piston cylinder is provided in the side groove, a piston block is slidably connected in the piston cylinder, and a fourth spring is provided between the piston block and the piston cylinder; a water inlet pipe and a water outlet pipe are connected to the piston cylinder, the end of the water inlet pipe away from the piston cylinder passes through the box body and is connected to the water tank, the end of the water outlet pipe away from the piston cylinder is connected to an atomizing nozzle, and the free end of the atomizing nozzle is arranged toward the wall block; a cam is coaxially connected to the circular shaft, the cam is abutted against the piston block, and the cam can rotate in the side groove; a filter screen is provided in the box body, and the filter screen is located between the bottom of the partition and the bottom of the box body.

[0025] Through the above arrangement, during the rotation of the circular shaft, the circular shaft will also drive the cam to rotate. When the raised part of the cam squeezes the piston block, the piston block moves downward and the fourth spring is compressed; when the raised part of the cam no longer squeezes the piston block, the piston block moves upward under the action of the fourth spring. Therefore, the piston block can reciprocate vertically, and then can continuously spray the clean water in the water tank from the atomizing nozzle through the water inlet pipe, the piston cylinder, and the water outlet pipe, so that the water mist passes through the through hole and acts on the mesh plate, which can have a flushing effect on the mesh plate; and the water mist and the bristles can enhance the cleaning effect on the mesh plate and avoid clogging of the mesh plate; in addition, the water mist can also reduce dust in the box body, so that the mixture of water and dust is collected to the bottom of the box body through the filter net.

[0026] Furthermore, a plurality of crushing teeth are arranged on the top of the mesh plate.

[0027] Through the above arrangement, during the vertical reciprocating motion of the mesh plate, the mesh plate drives the crushing teeth to move synchronously, and the crushing effect on the waste slag can be further enhanced through the cooperation of the crushing teeth and the crushing rollers.

[0028] The invention also provides a method for using a waste residue recovery device for zirconium dioxide production, so as to solve the problem that the existing recovery device pulverizes waste materials unevenly.

[0029] To achieve the above object, the present invention adopts the following technical solution: a method for using a waste slag recovery device for zirconium dioxide production, comprising the following steps:

[0030] Step 1: Introduce the waste residue into the box through the feed inlet;

[0031] Step 2: The introduction mechanism can intermittently introduce the waste slag into the space between the movable plate and the mesh plate through the feed opening;

[0032] Step 3: The rotating shaft is driven to rotate by the driving mechanism, and the rotating shaft drives the elliptical block and the crushing roller to rotate. When the two long-axis ends of the elliptical block are respectively against the movable plate and the mesh plate, the movable plate and the mesh plate are separated, and the first spring and the second spring are compressed; when the two short-axis ends of the elliptical block are respectively against the movable plate and the mesh plate, the movable plate moves in the opposite direction under the action of the first spring, and the mesh plate moves in the opposite direction under the action of the second spring, and the movable plate and the mesh plate are close to each other, so that the waste residue is close to the crushing roller, and the waste residue can be crushed by the rotating crushing roller, and the crushed particles can be screened by the mesh plate, so that the waste residue particles of qualified size are collected at the bottom of the box;

[0033] Step 4: After the waste residue is crushed, the sealing block is removed from the discharge port to obtain the waste residue particles. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The specific implementation process is as follows:

[0049] When in use, the waste slag is introduced into the box body 10 through the feed port 12. The waste slag is divided into two parts by the partition 20 and moves to the two sides of the partition 20 respectively, so that the waste slag falls to the top of the movable plate 25. At the same time, the waste slag on one side of the partition 20 is located between the partition 20 and the vertical plate 33, which can achieve the effect of temporary centralized storage and prevent the waste slag from scattering everywhere so that it can all pass through the discharge port.

[0050] Start the motor 29, and the output shaft of the motor 29 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the elliptical block 24 to rotate. When the two long-axis ends of the elliptical block 24 respectively abut against the movable plate 25 and the mesh plate 27, the movable plate 25 moves upward and the mesh plate 27 moves downward, so that the movable plate 25 and the mesh plate 27 are separated, and the first spring 26 and the second spring 28 are compressed; when the two short-axis ends of the elliptical block 24 respectively abut against the movable plate 25 and the mesh plate 27, the movable plate 25 moves in the opposite direction under the action of the first spring 26, and the mesh plate 27 moves in the opposite direction under the action of the second spring 28, so that the movable plate 25 and the mesh plate 27 are close to each other; therefore, the movable plate 25 and the mesh plate 27 continue to approach and move away, and the movable plate 25 and the mesh plate 27 can reciprocate vertically.

[0051] When the movable plate 25 moves upward, the movable plate 25 drives the baffle plate 32 to move upward, and at the same time, the baffle plate 32 also moves laterally along the path of the inclined groove 30 through the auxiliary block, that is, the two baffle plates 32 move away from each other, so that the shielding effect of the baffle plate 32 on the discharge port disappears, and then the waste residue on the top of the movable plate 25 moves through the discharge port to between the movable plate 25 and the mesh plate 27; when the movable plate 25 moves downward, the movable plate 25 drives the baffle plate 32 to move downward, and at the same time, the baffle plate 32 also moves laterally in the opposite direction along the path of the inclined groove 30 through the auxiliary block, that is, the two baffle plates 32 are close to each other, so that the baffle plate 32 blocks the discharge port, and then prevents the waste residue on the top of the movable plate 25 from passing through the discharge port and moving between the movable plate 25 and the mesh plate 27; therefore, intermittent and quantitative discharge of the waste residue can be achieved, so as to better crush the waste residue and make the crushing effect more uniform.

[0052] After the waste slag is located between the movable plate 25 and the mesh plate 27, the movable plate 25 and the mesh plate 27 continue to approach and move away from each other, so that the waste slag can be pushed close to the crushing roller 11; during the rotation of the rotating shaft 21, the rotating shaft 21 will also drive the crushing roller 11 to rotate, and the rotating crushing roller 11 can crush the waste slag particles so that the waste slag particles of qualified size fall down through the mesh plate 27, and the waste slag particles of unqualified size remain on the mesh plate 27; since the movable plate 25 and the mesh plate 27 continue to approach and move away from each other, the waste slag particles of unqualified size can be continuously replaced, and they are pushed to continue to approach the crushing roller 11, so as to perform multiple crushing processes, thereby ensuring that the waste slag can be crushed into waste slag particles of qualified size, that is, ensuring the utilization rate of waste slag recovery.

[0053] During the rotation of the rotating shaft 21, the rotation will also drive the cylindrical block 41 to rotate, and the push block 45 can reciprocate laterally along the path of the curved groove 42 through the linkage block 43, and then the waste residue between the movable plate 25 and the mesh plate 27 can be pushed to move in the direction of the partition 20 through the push block 45, so that the waste residue passes over the elliptical block 24, so that all the waste residue can be crushed and processed by the crushing roller 11, thereby improving the utilization rate of waste residue recovery; and, during the lateral reciprocating movement of the push block 45, the push block 45 will also drive the lifting block 47 to move synchronously, and the third spring 48 changes its shape as the distance between the movable plate 25 and the mesh plate 27 changes; that is, the height of the push block 45 is extended by the lifting block 47, and the range of action of the push block 45 on the waste residue is expanded, so that all the waste residue between the movable plate 25 and the mesh plate 27 can be pushed to move; in addition, the guide wheel 49 replaces the lifting block 47 to contact the movable plate 25 and the mesh plate 27, which can reduce the friction force and make the lateral movement of the push block 45 and the lifting block 47 smoother.

[0054] When the mesh plate 27 moves downward, the mesh plate 27 drives the second rack 62 to move downward, the second rack 62 engages with the second gear 65 to drive the circular shaft 63 to rotate, the circular shaft 63 drives the first gear 64 to rotate, the first gear 64 engages with the first rack 61 to drive the first rack 61 to move away from the partition 20; when the mesh plate 27 moves upward, the mesh plate 27 drives the second rack 62 to move upward, the second rack 62 engages with the second gear 65 to drive the circular shaft 63 to rotate in the opposite direction, the circular shaft 63 drives the first gear 64 to rotate in the opposite direction, the first gear 64 engages with the first rack 61 to drive the first rack 61 to move in the direction of the partition 20; therefore, the first rack 61 can realize horizontal reciprocating motion.

[0055] When the first rack 61 moves in the direction away from the partition 20, the first rack 61 drives the wall block 51 to move synchronously, and the wall block 51 drives the bristles 53 to move synchronously, so that the bristles 53 continuously enter and exit the mesh plate 27, thereby cleaning the mesh plate 27 and preventing the mesh plate 27 from being blocked; the waste particles passing through the mesh plate 27 can pass through the through hole 52 and fall onto the filter screen 78.

[0056] During the rotation of the circular shaft 63, the circular shaft 63 will also drive the cam 77 to rotate. When the raised portion of the cam 77 squeezes the piston block 72, the piston block 72 moves downward and the fourth spring 73 is compressed; when the raised portion of the cam 77 no longer squeezes the piston block 72, the piston block 72 moves upward under the action of the fourth spring 73. Therefore, the piston block 72 can reciprocate vertically, and then can continuously spray the clean water in the water tank 70 from the atomizing nozzle 76 through the water inlet pipe 74, the piston cylinder 71, and the water outlet pipe 75, so that the water mist passes through the through hole 52 and acts on the mesh plate 27, which can have a flushing effect on the mesh plate 27; and the water mist and the bristles 53 can enhance the cleaning effect on the mesh plate 27 and avoid clogging of the mesh plate 27; in addition, the water mist can also reduce dust in the box body 10, so that the mixture of water and dust is collected to the bottom of the box body 10 through the filter screen 78.

[0057] After the waste residue is crushed, the sealing block 14 is removed from the discharge port 13 to obtain waste residue particles.

[0058] In this embodiment, a plurality of crushing teeth 80 are fixedly connected to the top of the mesh plate 27; during the vertical reciprocating motion of the mesh plate 27, the mesh plate 27 drives the crushing teeth 80 to move synchronously, and the crushing effect of the waste residue can be further enhanced through the cooperation of the crushing teeth 80 and the crushing roller 11.

[0059] In this embodiment, a discharge port 90 is opened on the right side wall of the box body 10 near the bottom of the box body 10 , and the discharge port 90 is located below the filter screen 78 ; the mixture of water and dust can be discharged through the discharge port 90 .

[0060] This embodiment also provides a method for using a waste slag recovery device for zirconium dioxide production, comprising the following steps:

[0061] Step 1: Introduce the waste residue into the box body 10 through the feed port 12.

[0062] Step 2: The waste residue is divided into two parts by the partition 20 and moves to both sides of the partition 20 respectively, so that the waste residue falls to the top of the movable plate 25, and the waste residue on one side of the partition 20 is located between the partition 20 and the vertical plate 33.

[0063] Step three: start the motor 29, the output shaft of the motor 29 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the elliptical block 24 to rotate. When the two long-axis ends of the elliptical block 24 respectively abut against the movable plate 25 and the mesh plate 27, the movable plate 25 moves upward and the mesh plate 27 moves downward, so that the movable plate 25 and the mesh plate 27 are separated, and the first spring 26 and the second spring 28 are compressed; when the two short-axis ends of the elliptical block 24 respectively abut against the movable plate 25 and the mesh plate 27, the movable plate 25 moves in the opposite direction under the action of the first spring 26, and the mesh plate 27 moves in the opposite direction under the action of the second spring 28, so that the movable plate 25 and the mesh plate 27 are close to each other; therefore, the movable plate 25 and the mesh plate 27 continue to approach and move away, and the movable plate 25 and the mesh plate 27 can reciprocate vertically.

[0064] When the movable plate 25 moves upward, the movable plate 25 drives the baffle 32 to move upward, and at the same time, the baffle 32 also moves laterally along the path of the inclined groove 30 through the auxiliary block, that is, the two baffles 32 move away from each other, so that the blocking effect of the baffle 32 on the discharge port disappears, and then the waste residue on the top of the movable plate 25 moves through the discharge port to between the movable plate 25 and the mesh plate 27; when the movable plate 25 moves downward, the movable plate 25 drives the baffle 32 to move downward, and at the same time, the baffle 32 also moves laterally in the opposite direction along the path of the inclined groove 30 through the auxiliary block, that is, the two baffles 32 are close to each other, so that the baffle 32 blocks the discharge port, and then prevents the waste residue on the top of the movable plate 25 from passing through the discharge port and moving between the movable plate 25 and the mesh plate 27; therefore, intermittent and quantitative discharge of waste residue can be achieved.

[0065] After the waste slag is located between the movable plate 25 and the mesh plate 27, the movable plate 25 and the mesh plate 27 continue to approach and move away from each other, so that the waste slag can be pushed close to the crushing roller 11; during the rotation of the rotating shaft 21, the rotating shaft 21 will also drive the crushing roller 11 to rotate, and the rotating crushing roller 11 can crush the waste slag particles so that the waste slag particles of qualified size fall down through the mesh plate 27, and the waste slag particles of unqualified size remain on the mesh plate 27; since the movable plate 25 and the mesh plate 27 continue to approach and move away from each other, the waste slag particles of unqualified size can be continuously replaced, so that they can continue to approach the crushing roller 11, so as to perform multiple crushing processes, thereby ensuring that the waste slag can be crushed into waste slag particles of qualified size.

[0066] The waste residue between the movable plate 25 and the mesh plate 27 can move to the right side of the elliptical block 24, so that it cannot be crushed by the crushing roller 11; during the rotation of the rotating shaft 21, the rotation will also drive the cylindrical block 41 to rotate, and the push block 45 can reciprocate laterally along the path of the curved groove 42 through the linkage block 43, and then the push block 45 can push the waste residue between the movable plate 25 and the mesh plate 27 to move in the direction of the partition 20, so that the waste residue passes over the elliptical block 24, so that all the waste residue can be crushed by the crushing roller 11; and, during the lateral reciprocating motion of the push block 45, the push block 45 will also drive the lifting block 47 to move synchronously, and the third spring 48 will change its shape as the distance between the movable plate 25 and the mesh plate 27 changes, and then the push block 45 and the lifting block 47 can push all the waste residue between the movable plate 25 and the mesh plate 27 to move; in addition, during the lateral motion of the lifting block 47, the lateral block drives the guide wheel 49 to move synchronously, so that the guide wheel 49 is in friction contact with the movable plate 25 and the mesh plate 27.

[0067] When the mesh plate 27 moves downward, the mesh plate 27 drives the second rack 62 to move downward, the second rack 62 engages with the second gear 65 to drive the circular shaft 63 to rotate, the circular shaft 63 drives the first gear 64 to rotate, the first gear 64 engages with the first rack 61 to drive the first rack 61 to move away from the partition 20; when the mesh plate 27 moves upward, the mesh plate 27 drives the second rack 62 to move upward, the second rack 62 engages with the second gear 65 to drive the circular shaft 63 to rotate in the opposite direction, the circular shaft 63 drives the first gear 64 to rotate in the opposite direction, the first gear 64 engages with the first rack 61 to drive the first rack 61 to move in the direction of the partition 20; therefore, the first rack 61 can realize horizontal reciprocating motion.

[0068] When the first rack 61 moves in the direction away from the partition 20, the first rack 61 drives the wall block 51 to move synchronously, and the wall block 51 drives the bristles 53 to move synchronously, so that the bristles 53 continuously enter and exit the mesh plate 27, thereby cleaning the mesh plate 27; the waste particles passing through the mesh plate 27 can pass through the through hole 52 and fall onto the filter screen 78.

[0069] During the rotation of the circular shaft 63, the circular shaft 63 will also drive the cam 77 to rotate. When the raised portion of the cam 77 squeezes the piston block 72, the piston block 72 moves downward and the fourth spring 73 is compressed; when the raised portion of the cam 77 no longer squeezes the piston block 72, the piston block 72 moves upward under the action of the fourth spring 73. Therefore, the piston block 72 can reciprocate vertically, and then can continuously spray the clean water in the water tank 70 from the atomizing nozzle 76 through the water inlet pipe 74, the piston cylinder 71, and the water outlet pipe 75, so that the water mist passes through the through hole 52 and acts on the mesh plate 27, which can have a flushing effect on the mesh plate 27; and the water mist and the bristles 53 can clean the mesh plate 27; in addition, the water mist can also play a dust reduction role in the box body 10, so that the mixture of water and dust is collected to the bottom of the box body 10 through the filter screen 78.

[0070] Step 4: After the waste residue is crushed, the sealing block 14 is removed from the discharge port 13 to obtain waste residue particles.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
