[0014] Compared with related technologies, the rare earth polishing fluid filtration, regeneration, and recycling equipment provided by this utility model has the following beneficial effects:

[0015] This invention provides a rare earth polishing liquid filtration, regeneration, and recycling device. Rare earth polishing liquid from a storage tank is introduced into a filter box via a drain pipe. The liquid is filtered through a filter screen, and the filtered liquid is guided to the bottom inner wall of the filter box for sedimentation via a guide bucket. A scraping mechanism scrapes the filter material on the filter screen along the cleaning opening into the collection box. A clear liquid extraction mechanism extracts the settled clear liquid.

A first servo motor and bevel gear drive a horizontal shaft to rotate, which in turn drives a cover plate to rotate, controlling the opening and closing of the cover plate. A second servo motor drives a screw to rotate, which in turn moves a sliding plate and a scraper laterally. The scraper removes the filter material... The filter material on the screen is scraped into the collection box through the cleaning opening. An electric cylinder moves the L-shaped plate, the liquid pump, and the turbidity sensor up and down. The turbidity sensor monitors the turbidity of the rare earth polishing solution, allowing the liquid pump to be inserted between the sediment layer and the clear liquid layer. The clear liquid is then extracted and discharged through the drain pipe. An air pump and a pressurization pipe inject air into the storage tank, increasing the air pressure inside the tank and allowing the rare earth polishing solution to pass through the filter screen more quickly, thus improving filtration efficiency. The rare earth polishing solution is introduced into the storage tank through the inlet pipe, and the inlet valve controls the opening and closing of the inlet pipe. A radar level sensor monitors the liquid level in the storage tank. The sediment in the filter box is discharged through the slag discharge pipe, and the slag discharge valve controls the opening and closing of the slag discharge pipe. Attached Figure Description

The filter material on the filter screen 4 can be scraped along the cleaning opening 6 into the collection box 7 through the scraping mechanism. The clear liquid after sedimentation can be extracted through the clear liquid extraction mechanism.

[0023] The bottom of the collection box 7 is provided with a slag discharge port 8, and a sealing cover 9 is installed on the slag discharge port 8.

The turbidity sensor 24 is a TSW-10 model. The electric cylinder 20 can drive the L-shaped plate 21, the liquid pump 22, and the turbidity sensor 24 to move up and down. The turbidity sensor 24 can monitor the turbidity of the rare earth polishing liquid, thereby extending the liquid pump 22 between the rare earth polishing liquid sediment layer and the clear liquid layer, and extracting the clear liquid through the liquid pump 22 and discharging it through the drain pipe 23.

[0027] The top of the liquid storage tank 2 is equipped with a pressurization mechanism, which includes: an air pump 25 fixedly installed on the top of the liquid storage tank 2; a pressurization pipe 26 located at the exhaust end of the air pump 25 and connected to the liquid storage tank 2; a one-way valve 27 located on the pressurization pipe 26; and an exhaust pipe 28 with an exhaust valve 29 installed on the liquid storage tank 2.

[0028] The storage tank 2 is equipped with an inlet pipe 30 and an inlet valve 31. A radar level sensor 32, model 001-V-LD1, is installed on the inner top wall of the storage tank 2.

[0030] The working principle of the rare earth polishing fluid filtration, regeneration, and recycling equipment provided by this utility model is as follows:

[0031] Rare earth polishing slurry is introduced into the storage tank 2 through the inlet pipe 30. The inlet valve 31 controls the opening and closing of the inlet pipe 30. The radar level sensor 32 monitors the liquid level in the storage tank 2. The rare earth polishing slurry in the storage tank 2 is introduced into the filter box 1 through the outlet pipe 3. The rare earth polishing slurry is filtered through the filter screen 4. The filtered rare earth polishing slurry is guided to the bottom inner wall of the filter box 1 for sedimentation through the guide funnel 5. Air is injected into the storage tank 2 through the air pump 25 and the pressurization pipe 26, thereby increasing the air pressure in the storage tank 2 and enabling the rare earth polishing slurry to be processed more quickly. The material passes quickly through the filter screen 4, thereby improving the filtration efficiency. When it is necessary to clean the filter material on the filter screen 4, the first servo motor 13 and the bevel gear 14 drive the horizontal shaft 10 to rotate. The horizontal shaft 10 drives the cover plate 12 to rotate through the rotating plate 11, thereby opening the cover plate 12. The second servo motor 16 drives the screw 15 to rotate. The rotation of the screw 15 can drive the sliding plate 17 and the scraper 18 to move laterally. The scraper 18 can scrape the filter material on the filter screen 4 along the cleaning opening 6 into the collection box 7. The filter material collected in the collection box 7 can be discharged by unscrewing the sealing cover 9 and through the slag discharge port 8.

[0032] After the rare earth polishing slurry settles in the filter box 1, the electric cylinder 20 can drive the L-shaped plate 21, the pump 22 and the turbidity sensor 24 to move up and down. The turbidity of the rare earth polishing slurry can be monitored by the turbidity sensor 24. The pump 22 is then inserted between the sediment layer and the clear liquid layer of the rare earth polishing slurry. The clear liquid is then extracted by the pump 22 and discharged through the drain pipe 23.

[0033] The sediment in the filter box 1 can be discharged through the slag discharge pipe 33, and the opening and closing of the slag discharge pipe 33 can be controlled by the slag discharge valve 34.

[0035] This utility model provides a rare earth polishing liquid filtration, regeneration, and recycling device. The rare earth polishing liquid in the storage tank 2 is introduced into the filter box 1 through the liquid outlet pipe 3. The rare earth polishing liquid is filtered through the filter screen 4. The filtered rare earth polishing liquid is guided to the bottom inner wall of the filter box 1 for sedimentation through the guide hopper 5. A scraping mechanism scrapes the filter material on the filter screen 4 along the cleaning opening 6 into the collection box 7. A clear liquid extraction mechanism extracts the sedimented clear liquid. The collected filter material in the collection box 7 is discharged through the discharge port 8 by unscrewing the sealing cap 9. A first servo motor 13 and a bevel gear 14 drive the horizontal shaft 10 to rotate. The horizontal shaft 10 drives the cover plate 12 to rotate through the rotating plate 11, thereby controlling the opening and closing of the cover plate 12. A second servo motor 16 drives the screw 15 to rotate. The rotation of the screw 15 causes the sliding plate 17 and the scraper 18 to move laterally. The scraper 18 removes the sediment from the filter screen 4. The filtered material is scraped along the cleaning opening 6 into the collection box 7. The electric cylinder 20 can drive the L-shaped plate 21, the liquid pump 22, and the turbidity sensor 24 to move up and down. The turbidity sensor 24 can monitor the turbidity of the rare earth polishing liquid. The liquid pump 22 is then inserted between the rare earth polishing liquid sediment layer and the clear liquid layer. The liquid pump 22 draws out the clear liquid and discharges it through the drain pipe 23. Air can be injected into the storage tank 2 through the air pump 25 and the pressurization pipe 26, thereby increasing the air pressure in the storage tank 2 and allowing the rare earth polishing liquid to pass through the filter screen 4 more quickly, thereby improving the filtration efficiency. The rare earth polishing liquid is introduced into the storage tank 2 through the liquid inlet pipe 30. The liquid inlet valve 31 can control the opening and closing of the liquid inlet pipe 30. The radar liquid level sensor 32 can monitor the liquid level in the storage tank 2. The sediment in the filter box 1 can be discharged through the slag discharge pipe 33.
