Description

Technical Field

[0001] This invention relates to the field of iron oxide preparation, and more particularly to a purification system for iron oxide preparation. Background Technology

[0002] Iron oxide, also known as ferric oxide, calcined limonite, calcined ochre, iron oxide, iron red, etc., is a reddish-brown powder. In the process of preparing iron oxide, it needs to undergo purification processing to obtain a purer material.

[0003] In the process of purifying iron oxide, it is necessary to remove impurities from the surface of the iron oxide. The common method is to use water to stir and rinse. However, during the stirring process, due to the presence of impurities and the collision between the water and the impurities, a lot of foam is generated, and some of the impurities are contained in the foam. In existing purification devices, the water is discharged from the bottom after the washing and solid-liquid separation. As a result, the impurities in the foam still remain in the iron oxide, requiring multiple washings to meet the purification standard, which affects the improvement of purification efficiency. Therefore, this solution proposes an impurity reduction and purification system for iron oxide preparation. Summary of the Invention

[0004] The present invention proposes a purification system for the preparation of iron oxide, which solves the problem in the prior art that it is inconvenient to remove the foam generated during the cleaning process of iron oxide in advance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A purification system for the preparation of iron oxide includes:

[0007] The impurity removal mechanism includes a base, a mounting bracket installed on the top of the base, a cleaning tank, and a movable cylinder movably fitted inside the inner ring of the cleaning tank. A stirring shaft is rotatably connected to the bottom inner wall of the cleaning tank, and a scraper is installed on one side of the bottom of the stirring shaft. A receiving groove is fitted on the top of the outer periphery of the movable cylinder. A telescopic component for driving the movable cylinder to rise and fall is installed on the cleaning tank. A discharge port is opened on one side of the bottom surface of the cleaning tank, and a sealing plate is provided outside the discharge port.

[0008] An adjustment mechanism is installed on the outer wall of the cleaning tank and is used to drive the sealing plate to move. The sealing plate cooperates with the telescopic component to drive the sealing plate to close or open the discharge port during the lifting and lowering of the movable cylinder.

[0009] The filtration mechanism includes a water receiving tank installed on the top of the base, a filter cylinder fixed on the top of the water receiving tank, and a movable ring rotatably sleeved on the outer ring of the filter cylinder. A filter screen is installed inside the filter cylinder, and a material discharge port is opened on the filter screen along its radial direction. A material conveying pipe is installed at the bottom of the material discharge port, and one end of the material conveying pipe extends to the outside of the water receiving tank. A scraper is provided on the inner ring of the filter cylinder, and the top of the scraper is fixedly connected to the inner ring of the movable ring.

[0010] The linkage mechanism includes a gear ring sleeved on the outside of the movable ring and a linkage component installed at the bottom of the cleaning tank. The linkage component is connected to the stirring shaft and the gear ring for driving the gear ring to rotate when the stirring shaft rotates.

[0011] A suction mechanism is installed outside the water receiving tank and is connected to the movable ring for driving, so as to extract air out of the water receiving tank while the movable ring rotates.

[0012] The above technical solution not only allows for the convenient and effective removal of scum generated during the cleaning process from the top of the liquid surface, but also enables the automatic re-cleaning of the cleaned material, thus improving the quality and efficiency of purification and impurity removal.

[0013] As a further improvement to the above solution, the telescopic component includes a movable plate movably sleeved on the outer periphery of the cleaning tank, multiple movable rods fixed on the top surface of the movable plate, and multiple electric telescopic rods installed on the outer periphery of the cleaning tank. The output ends of the multiple electric telescopic rods are all fixedly connected to the bottom surface of the movable plate, and the tops of the multiple movable rods are all fixedly connected to the bottom surface of the receiving trough.

[0014] The above technical solution can drive the movable cylinder to move up and down.

[0015] As a further improvement to the above solution, the adjusting mechanism includes two screws threadedly connected to the sealing plate and two driving components installed on the bottom surface of the movable plate for driving the two screws to rotate. One end of each screw is rotatably connected to the outer circumference of the cleaning tank, and the other end of each screw is fixed with a connecting gear. The driving component includes a connecting plate fixed to the bottom surface of the movable plate and a movable rack slidably connected to the outer wall of one side of the connecting plate via a sliding joint. The movable rack meshes with one of the connecting gears. A limiting groove is provided on one side of the connecting plate along its length direction. The sliding joint includes a limiting post fixed in the limiting groove along its length direction and a sliding sleeve slidably connected to the outside of the limiting post. One end of the sliding sleeve is fixedly connected to the movable rack.

[0016] The above technical solution can automatically drive the sealing plate to open and close while the movable plate is raised and lowered, thereby achieving the purpose of automatic material discharge.

[0017] As a further improvement to the above solution, the bottom of the stirring shaft extends to the bottom of the cleaning tank, and the linkage includes a driven gear rotatably connected to the bottom surface of the cleaning tank and a driving gear fixed to the bottom of the stirring shaft and meshing with the driven gear, wherein the driven gear meshes with a gear ring.

[0018] The above technical solution allows the rotation of the stirring shaft to drive the rotation of the moving ring.

[0019] As a further improvement to the above solution, the suction mechanism includes a toothed ring fixed to the bottom surface of the movable ring and multiple air cylinders installed on the outer periphery of the water receiving tank. The toothed ring is movably sleeved on the outside of the movable ring. The top of each air cylinder has an opening, and a piston plate that can move along its axial direction is provided inside the air cylinder. An air outlet pipe and an air intake pipe communicating with the inside of the water receiving tank are installed at the bottom of the air cylinder. Both the air outlet pipe and the air intake pipe are equipped with one-way valves. The suction mechanism also includes multiple transmission components installed on the outer periphery of the filter cylinder and used to drive the piston plates in the multiple air cylinders to move up and down respectively. Each transmission component includes a connecting rod hinged to the top surface of the piston plate, a rotating shaft rotatably connected to the outer periphery of the filter cylinder, a U-shaped shaft fixed to one end of the rotating shaft, and a movable sleeve movably sleeved on the U-shaped shaft. The other end of the connecting rod is fixedly connected to the movable sleeve. A linkage gear that meshes with the toothed ring is sleeved on the outer periphery of the rotating shaft. In the multiple air cylinders, the movement direction of the piston plates in half of the air cylinders is opposite to the movement direction of the piston plates in the other half of the air cylinders.

[0020] The above technical solution allows the suction mechanism to be driven by the rotation of the movable ring, thereby drawing air out of the water tank while the movable ring is rotating, achieving the purpose of filtration.

[0021] As a further improvement to the above solution, the outer ring of the movable cylinder is provided with an installation groove coaxially arranged therewith. An inflation sealing ring is installed in the installation groove. An inflation pipe communicating with the inflation sealing ring is fixed on the outer periphery of the movable cylinder. A valve one is installed on the inflation pipe. A venting pipe is also installed on the outer periphery of the inflation pipe. A valve two is installed on the venting pipe.

[0022] The above technical solution utilizes an inflatable sealing ring after inflation to achieve a seal, which enhances the sealing effect without affecting the lifting and lowering of the movable cylinder.

[0023] As a further improvement to the above solution, a scraper ring is fixed at the bottom of the movable cylinder, and the inner ring of the scraper ring has a trumpet-shaped structure that is narrow at the top and wide at the bottom.

[0024] The above technical solution utilizes a scraper ring that can scrape material off the inner wall of the cleaning tank as it descends.

[0025] As a further improvement to the above solution, a cleaning mechanism is also included. The cleaning mechanism includes a water tank installed at the bottom of the cleaning tank, a hollow mounting shaft rotatably connected to the top surface of the filter screen, a scraper three fixed to the outer periphery of the mounting shaft, and a cleaning pipe. The cleaning pipe is located between scraper three and scraper two, and there is a 1-2 cm gap between the bottom surface of scraper three and the top surface of the filter screen. The mounting shaft is coaxially arranged with the filter cylinder. One end of scraper two is fixedly connected to the outer periphery of the mounting shaft. The outer periphery of the water receiving tank is fitted with multiple air supply pipes that communicate with the air outlet pipe. The other end of the air supply pipe extends into the water tank. A water outlet pipe is installed on the top side of the water tank. One end of the water outlet pipe extends into the water tank, and the other end of the water outlet pipe is rotatably connected to the top of the mounting shaft. The water outlet pipe communicates with the inside of the mounting shaft. The bottom surface of the cleaning pipe has multiple water outlets, and the cleaning pipe communicates with the inside of the mounting shaft.

[0026] The above technical solution allows the material on the top surface of the filter screen to be scraped flat while the moving ring rotates, and then rinsed again with clean water, thereby improving the impurity removal effect.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. Through the cooperation between the telescopic component, the movable cylinder, and the receiving trough, the movable cylinder can be driven to descend after the cleaning is completed. This allows the foam generated during the cleaning process to be discharged from the top of the movable cylinder and fall into the receiving trough, and then discharged from the receiving trough. This avoids the impurities contained in the foam remaining on the material surface when draining from the bottom, thereby improving the cleaning quality and avoiding multiple cleanings.

[0029] 2. Through the cooperation between the adjustment mechanism and the telescopic component, after the foam is discharged by the movement of the cylinder, the adjustment mechanism is driven to open the sealing plate during the descent of the movement plate, so that the material in the cleaning tank can be discharged from the outlet. Furthermore, the adjustment mechanism can be automatically driven to close the sealing plate again during the ascent of the movement plate.

[0030] 3. Through the cooperation between the stirring shaft, the linkage mechanism and the moving ring, the moving ring can be driven to rotate at the same time as the stirring shaft rotates, thereby using the scraper to scrape the material falling on the filter screen into the discharge port for discharge.

[0031] 4. The cleaning mechanism can flatten the material falling into the filter cylinder and rinse it again. Then, the water is filtered and discharged through the discharge hole, which can further remove the impurities remaining on the surface of the material.

[0032] 5. By coordinating the air-filled sealing ring, the air-filling pipe, and the air-venting pipe, air can be filled into the air-filled sealing ring before impurity removal, causing it to expand and come into contact with the inner wall of the cleaning tank, thus achieving a sealing effect. After impurity removal, the air in the air-filled sealing ring is discharged through the air-venting pipe, allowing the movable cylinder to move up and down. Attached Figure Description

[0043] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0044] Example 1

[0045] Please combine Figure 1-8 This embodiment provides a purification system for the preparation of iron oxide, comprising:

[0046] The impurity removal mechanism includes a base, a mounting bracket 1 mounted on top of the base, a cleaning tank 2, and a movable cylinder 3 movably fitted inside the cleaning tank 2. A stirring shaft 8 is rotatably connected to the bottom inner wall of the cleaning tank 2. Multiple stirring rods are fixed to the outer periphery of the stirring shaft 8. A scraper 9 is mounted on one side of the bottom of the stirring shaft 8. A motor is mounted on the top of the mounting bracket 1, and one end of the motor's output shaft is connected to the top of the stirring shaft 8. The bottom surface of the cleaning tank 2 is an upwardly convex conical structure. The bottom surface of the scraper 9 abuts against the bottom surface of the cleaning tank 2, and the end of the scraper 9 away from the stirring shaft 8 abuts against the inner wall of the cleaning tank 2. A receiving groove 4 is fitted onto the top of the outer periphery of the movable cylinder 3, and a drain pipe is installed around the outer periphery of the receiving groove 4. A telescopic component for driving the movable cylinder 3 to rise and fall is installed on the cleaning tank 2. The telescopic component includes a movable plate 11 movably fitted around the outer periphery of the cleaning tank 2 and multiple rods fixed to the top surface of the movable plate 11. The movable rod 5 and multiple electric telescopic rods 7 installed on the outer periphery of the cleaning tank 2 are provided. The output ends of the multiple electric telescopic rods 7 are fixedly connected to the bottom surface of the movable plate 11, and the top of the multiple movable rods 5 are fixedly connected to the bottom surface of the receiving trough 4. The outer side of the multiple movable rods 5 is movably fitted with a fixed plate 6. One side of the fixed plate 6 is fixedly connected to the outer wall of the cleaning tank 2, and the fixed plate 6 is located above the movable plate 11. When the movable plate 11 contacts the bottom surface of the fixed plate 6, the movable cylinder 3 is at the normal working height. The telescopic component can easily drive the movable cylinder 3 to rise and fall. When it is necessary to remove the foam generated after cleaning, the electric telescopic rod 7 can be activated to retract, thereby driving the movable cylinder 3 to fall. The liquid level in the movable cylinder 3 remains unchanged, so that the foam can flow out from the top surface of the lowered movable cylinder 3 and fall into the receiving trough 4. When the electric telescopic rod 7 extends, it can drive the movable cylinder 3 to rise.

[0047] A discharge port is provided on one side of the bottom surface of the cleaning tank 2. A sealing plate 41 is provided outside the discharge port. A sealing ring 42 is installed on the outer wall of the sealing plate 41 near the side of the cleaning tank 2. When the sealing plate 41 is tightly attached to the outer wall of the cleaning tank 2, it can block the discharge port.

[0048] An adjusting mechanism is installed on the outer wall of the cleaning tank 2 and is used to drive the sealing plate 41 to move. The sealing plate 41 cooperates with the telescopic component to drive the sealing plate 41 to close or open the discharge port during the lifting and lowering of the movable cylinder 3. The adjusting mechanism includes two screws 40 threadedly connected to the sealing plate 41 and two driving components installed on the bottom surface of the movable plate 11 to drive the two screws 40 to rotate. One end of each screw 40 is rotatably connected to the outer periphery of the cleaning tank 2, and the other end of each screw 40 is fixed with a connecting gear 39. The driving components include components fixed to the movable cylinder 11. The connecting plate 36 on the bottom surface of the plate 11 and the movable rack 38 slidably connected to the outer wall of one side of the connecting plate 36 via a sliding member. The movable rack 38 meshes with one of the connecting gears 39. A limiting groove is provided on one side of the connecting plate 36 along its length direction. The sliding member includes a limiting post 37 fixed in the limiting groove along its length direction and a sliding sleeve 47 slidably connected to the outside of the limiting post 37. One end of the sliding sleeve 47 is fixedly connected to the movable rack 38. During the extension and retraction process, the electric telescopic rod 7 will drive the movable plate 11 to move up and down synchronously. After the movable plate 11 descends, it will drive the connecting plate 36 to move up and down synchronously. As the sliding sleeve 47 descends, it does not yet contact the top of the limiting groove, so the movable rack 38 does not descend with the connecting plate 36. Only after the sliding sleeve 47 contacts the top of the limiting groove, at which point the foam inside the movable cylinder 3 has been discharged, does the movable plate 11 continue to descend. The movable rack 38 then descends synchronously with the connecting plate 36, thereby driving the connecting gear 39 to rotate forward, which in turn drives the screw 40 to rotate forward. During the forward rotation of the screw 40, the sealing plate 41 gradually moves away from the cleaning tank 2, allowing the material inside the cleaning tank 2 to be cleaned by the scraper. The material is discharged from the outlet under the rotation. Conversely, when the movable plate 11 rises, it will drive the connecting plate 36 to move upward synchronously. When the sliding sleeve 47 does not contact the bottom of the limiting groove, the movable rack 36 will not move upward synchronously with the connecting plate 36. When the sliding sleeve 47 contacts the bottom of the limiting groove, it will drive the movable rack 36 to move upward synchronously, thereby driving the connecting gear 39 to reverse, which can drive the sealing plate 41 to move closer to the cleaning tank 2. Finally, when the movable plate 11 abuts against the fixed plate 6, it will press the sealing plate 41 against the outside of the outlet, and then the electric telescopic rod 7 will stop extending.

[0049] The filtration mechanism includes a water receiving trough 21 mounted on the top of the base, a filter cylinder 24 fixed to the top of the water receiving trough 21, and a movable ring 16 rotatably sleeved on the outer ring of the filter cylinder 24. A filter screen 25 is installed inside the filter cylinder 24, and a material discharge port 29 is provided on the filter screen 25 along its radial direction. A conveying pipe 20 is installed at the bottom of the material discharge port 29, and one end of the conveying pipe 20 extends to the outside of the water receiving trough 21. A scraper 19 is provided on the inner ring of the filter cylinder 24. The top of the scraper 19 is fixed to the inner ring of the movable ring 16, the bottom surface of the scraper 19 abuts against the top surface of the filter screen 25, and one end of the scraper 19 abuts against the inner ring of the filter cylinder 24. When the movable ring 16 rotates, it drives the scraper 19 to rotate around the axis of the filter cylinder 24, thereby scraping the filtered material falling on the surface of the filter screen 25 into the material discharge port 29, and then discharging it from the conveying pipe 20.

[0050] The linkage mechanism includes a gear ring 32 sleeved on the outside of the movable ring 16 and a linkage component installed at the bottom of the cleaning tank 2. The linkage component is connected to the stirring shaft 8 and the gear ring 32 for driving the gear ring 32 to rotate when the stirring shaft 8 rotates. The bottom of the stirring shaft 8 extends to the bottom of the cleaning tank 2. The linkage component includes a driven gear 15 rotatably connected to the bottom surface of the cleaning tank 2 and a driving gear 14 fixed to the bottom of the stirring shaft 8 and meshing with the driven gear 15. The driven gear 15 meshes with the gear ring 32. When the stirring shaft 8 rotates, it drives the driving gear 14 to rotate. After the driving gear 14 rotates, it can drive the driven gear 15 to rotate. After the driven gear 15 rotates, it drives the gear ring 32 to rotate, so that the movable ring 16 rotates synchronously with the gear ring 32. In turn, it can drive the scraper 19 to rotate at the same time as the stirring shaft 8 rotates.

[0051] A suction mechanism is installed outside the water receiving tank 21 and is connected to the movable ring 16 for driving. It is used to extract air from the water receiving tank 21 as the movable ring 16 rotates. The suction mechanism includes a toothed ring 17 fixed to the bottom surface of the movable ring 16 and multiple air cylinders 22 installed around the outer periphery of the water receiving tank 21. The toothed ring 17 is movably sleeved on the outside of the movable ring 16. Each air cylinder 22 has an opening at its top and a piston plate 27 that can move axially inside. An air outlet pipe is installed at the bottom of each air cylinder 22. The suction mechanism also includes multiple transmission components 31 mounted on the outer periphery of the filter cylinder 24 and used to drive the piston plates 27 inside the multiple air cylinders 22 to move up and down. The transmission components include a connecting rod 26 hinged to the top surface of the piston plate 27, a rotating shaft 301 rotatably connected to the outer periphery of the filter cylinder 24, a U-shaped shaft 302 fixed to one end of the rotating shaft 301, and a movable sleeve 302 movably sleeved on the U-shaped shaft 302. 0. The other end of the connecting rod 26 is fixedly connected to the movable sleeve 30. The outer circumference of the rotating shaft 301 is sleeved with a linkage gear 33 that meshes with the gear ring 17. Among the multiple air cylinders 22, the movement direction of the piston plate 27 in half of the air cylinders 22 is opposite to that in the other half of the air cylinders 22. When the movable ring 16 rotates, it will drive the gear ring 17 to rotate. After the gear ring 17 rotates, it can drive multiple rotating shafts 301 to rotate simultaneously. By setting the opening direction of half of the U-shaped shafts 302 to be opposite to that of the other half of the U-shaped shafts 302, the piston plate 27 in one half of the air cylinders 22 can be moved upward while the rotating shaft 301 rotates, and the piston plate 27 in the other half of the air cylinders 22 can be moved downward. This ensures that the air in the water tank 21 can be continuously drawn out while the gear ring 17 rotates, thereby playing a role in filtration and accelerating the filtration speed of moisture in the material on the surface of the filter screen 25.

[0052] The implementation principle of this embodiment is as follows: During purification, first ensure that the movable plate 11 is in contact with the bottom surface of the fixed plate 6, then put the iron oxide to be purified into the cleaning tank 2, then inject clean water into the cleaning tank 2, and make the liquid level of the clean water in the movable cylinder 3. Then the motor can be started to rotate and drive the stirring shaft 8 to rotate, thereby cleaning and removing impurities from the iron oxide.

[0053] After the impurity removal is completed, the electric telescopic rod 7 is activated to retract, thereby driving the movable cylinder 3 to descend. The liquid level in the movable cylinder 3 remains unchanged, allowing the foam to flow out from the top of the descending movable cylinder 3 and fall into the receiving trough 4. When the sliding sleeve 47 abuts against the top of the limiting groove, the foam in the movable cylinder 3 has been discharged. Then, as the movable plate 11 continues to move down, the movable rack 38 descends synchronously with the connecting plate 36, thereby driving the connecting gear 39 to rotate forward, which in turn drives the screw 40 to rotate forward. During the forward rotation of the screw 40, the sealing plate 41 gradually moves away from the cleaning tank 2, allowing the material in the cleaning tank 2 to be discharged from the outlet and fall into the filter cylinder 24 under the rotation of the scraper 9.

[0054] While the stirring shaft 8 rotates, it drives the driving gear 14 to rotate. The driving gear 14 then drives the driven gear 15 to rotate. The driven gear 15 then drives the gear ring 32 to rotate, so that the movable ring 16 rotates synchronously with the gear ring 32. When the movable ring 16 rotates, it drives the scraper 19 to rotate around the axis of the filter cylinder 24, so that the material that has fallen on the surface of the filter screen 25 and been filtered can be scraped into the discharge port 29 and then discharged from the conveying pipe 20.

[0055] After the material in the cleaning tank 2 is emptied, the electric telescopic rod 7 is then activated to rise. When the movable plate 11 rises, it will drive the connecting plate 36 to move upward synchronously. When the sliding sleeve 47 does not contact the bottom of the limiting groove, the movable rack 36 will not move upward synchronously with the connecting plate 36. When the sliding sleeve 47 contacts the bottom of the limiting groove, it will drive the movable rack 36 to move upward synchronously, thereby driving the connecting gear 39 to reverse. This will drive the sealing plate 41 to move closer to the cleaning tank 2. Finally, when the movable plate 11 abuts against the fixed plate 6, the sealing plate 41 will be pressed against the outside of the discharge port. After that, the electric telescopic rod 7 will stop extending, and finally the motor can be stopped.

[0056] Example 2

[0057] Combination Figure 1 and Figure 5 This embodiment is further improved on the basis of embodiment 1 in that: the outer ring of the movable cylinder 3 is provided with a mounting groove coaxially arranged therewith, and an inflation sealing ring 44 is installed in the mounting groove. An inflation pipe 45 communicating with the inflation sealing ring 44 is fixed on the outer periphery of the movable cylinder 3. A valve one is installed on the inflation pipe 45. An air venting pipe 46 is also installed on the outer periphery of the inflation pipe 45. A valve two is installed on the air venting pipe 46. Air is inflated into the inflation sealing ring 44 through the inflation pipe 45, thereby using the inflated inflation sealing ring 44 to seal the gap between the cleaning tank 2 and the movable cylinder 3.

[0058] A scraper ring 43 is fixed at the bottom of the movable cylinder 3. The inner ring of the scraper ring 43 has a trumpet-shaped structure that is narrow at the top and wide at the bottom. When the movable cylinder 3 descends, the scraper ring 43 can scrape off the material stuck to the inner wall of the cleaning tank 2.

[0059] The implementation principle of this embodiment is as follows: When the movable cylinder 3 is raised to a state where it can be cleaned, valve one is opened first and valve two is closed. Then, air is injected into the air sealing ring 44 through the air inflator 45. The air sealing ring 44 then expands and presses against the inner wall of the cleaning tank 2, thereby achieving a sealing effect. Then, valve one is closed, which can prevent water in the cleaning tank 2 or the movable cylinder 3 from seeping out from the gap between the cleaning tank 2 and the movable cylinder 3. When it is necessary to raise or lower the movable cylinder 3, valve two can be opened, and the air in the air sealing ring 44 can be discharged through the vent pipe 46.

[0060] Example 3

[0061] Combination Figure 1-3 , Figure 6 and Figure 8 This embodiment, based on embodiments 1-2, further improves upon the following: it also includes a cleaning mechanism. The cleaning mechanism comprises a water tank 10 installed at the bottom of the cleaning tank 2, a hollow mounting shaft 18 rotatably connected to the top surface of the filter screen 25, a scraper 23 fixed to the outer periphery of the mounting shaft 18, and a cleaning pipe 28. The cleaning pipe 28 is located between scraper 23 and scraper 19, with a 1-2 cm gap between the bottom surface of scraper 23 and the top surface of the filter screen 25. This gap allows the material on the surface of the filter screen 25 to be scraped flat while scraper 23 rotates, and then rinsed again by the clean water discharged through the cleaning pipe 28. The mounting shaft 18 is coaxially arranged with the filter cylinder 24, one end of scraper 19 is fixedly connected to the outer periphery of the mounting shaft 18, and the outer periphery of the water tank 21 is sleeved with multiple air outlet pipes 31. An air supply pipe 12 is connected to the water tank 10, with one end extending into the water tank 10. A water outlet pipe 13 is installed on the top side of the water tank 10, with one end extending into the water tank 10 and the other end rotatably connected to the top of the mounting shaft 18. The water outlet pipe 13 is also connected to the inside of the mounting shaft 18. Multiple water outlets are provided on the bottom surface of the cleaning pipe 28, which is also connected to the inside of the mounting shaft 18. A water inlet pipe and a pressure relief pipe 48 are also installed on the water tank 10. A sealing cap is installed at the inlet of the water inlet pipe, and a valve 3 is installed on the pressure relief pipe 48. Before the material in the cleaning tank 2 is transported into the filter cartridge 24, the valve 3 is kept open to release the air pressure in the water tank 10 and prevent the water in the water tank 10 from being discharged from the water outlet pipe 13. When cleaning the material in the filter cartridge 24, the valve 3 can be closed.

[0062] The implementation principle of this embodiment is as follows: When cleaning the material in the filter cylinder 24, valve three is closed, and the air discharged from multiple air cylinders 22 is input into the water tank 10 through the air supply pipe 12. The air pressure in the water tank 10 increases accordingly, so that the water in the water tank 10 can be discharged through the water outlet pipe 13. Finally, the water enters the mounting shaft 18 and is discharged from the water outlet hole at the bottom of the cleaning pipe, spraying onto the surface of the material after it has been scraped flat by scraper three 23, thereby cleaning the material again. When valve three is opened, the air pressure in the water tank 10 is released through the pressure relief pipe 48, and the water in the water tank 10 will not be discharged.

[0063] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
