[0061] The filter purification box 205 drives the reciprocating frame 21 to perform lateral reciprocating motion. Since the lifting slot 24 guides the guide rod 22, when the reciprocating frame 21 moves horizontally left and right, the guide rod 22 moves along the inner wall of the lifting slot 24, so that the guide rod 22 drives the reciprocating frame 21 to perform lifting motion. The filter purification box 205 drives the filter membrane 302 to perform reciprocating lifting motion in the solution, so that the dirt on the surface of the filter membrane 302 is vibrated and then falls off, which is convenient for processing the solution, thereby improving the practicality and working efficiency of the device. The filter purification box 205 drives When the rotating shaft 301 and the filter membrane 302 move back and forth laterally, the gear 303 meshes with the tooth plate 304, so that the gear 303 can drive the rotating shaft 301 to rotate, thereby enabling the rotating shaft 301 to drive the filter membrane 302 to rotate, which is beneficial to the centrifugal force generated by the filter membrane 302 during the rotation, and the friction force generated by the filter membrane 302 and the solution during the rotation, so as to throw away the dirt adsorbed on the filter membrane 302, thereby reducing the stains on the outer surface of the filter membrane 302, reducing the number of times the staff cleans the filter membrane 302, and improving its use efficiency;

[0062] When the filter purification box 205 descends, the filter purification box 205 drives the lower pressure plate 401 to squeeze the squeezing plate 404, and the squeezing plate 404 squeezes the liquid entering the spray box 402. The liquid is discharged into the cleaning box 41 through the spray pipe 405 and discharged from the nozzle 42. The liquid cleans the filter membrane 302. The longitudinal slide bar 45 drives the cleaning box 41 to move synchronously with the filter membrane 302. During the synchronous movement, the filter membrane 302 rises and falls, so that the nozzle 42 sprays different positions of the filter membrane 302, thereby increasing the cleaning area of ​​the nozzle 42 and completely removing the impurities and dirt adhering to the outer surface of the filter membrane 302.

[0063] The reciprocating frame 21 drives the extension rod 604 to move left and right, and the extension rod 604 drives the movable plate 602 to move around the rotating shaft rod 601 through the push-pull slide groove 603. The movable plate 602 drives the convex slider 606 to move through the connecting rod 605. The convex slider 606 slides in the concave slide groove 608 and drives the scraping plate 607 to move. The scraping plate 607 scrapes the dirt adhered to the bottom wall of the purification tank 102, further improving the cleaning effect of the device. The material motor 502 drives the rotating shaft 503 to rotate, and the rotating shaft 503 drives the discharge conveyor belt 504 to move. The scraping plate 607 pushes the impurities to the surface of the discharge conveyor belt 504, and collects the impurities through the concave grooves on the discharge conveyor belt 504, so that the impurities are transported to the impurity collection box 506 through the discharge conveyor belt 504, which facilitates the collection of impurities precipitated at the bottom of the purification tank 102 and impurities floating on the liquid, and further facilitates the treatment of the slag liquid after collection.
