The second motor 7 drives the second rotating shaft 6 to rotate, thereby driving the connecting frame 5 to rotate, further driving the fixed plate 416 to rotate. The fixed plate 416 drives the installation block 428 to rotate, thereby driving the filtering box 1 to flip, further driving the upper surface of the filter plate 10 on the filtering box 1 to flip, so that the upper surface of the filter plate 10 faces downward. The impurities will fall under the action of gravity. Then start the first motor 417. The first motor 417 drives the control rod 425 to rotate, thereby driving the cam member 424 to rotate, further driving the slider 422 on the second connecting plate 423 to move up and down repeatedly. The slider 422 drives the connecting block 420 to move, thereby driving the toothed plate 419 to move back and forth repeatedly, further driving the gear 418 to rotate repeatedly. The gear 418 drives the rotating rod 413 to rotate, thereby driving the pulley wheel 414 to rotate, and further controlling the first rotating shaft 412 to rotate under the action of the belt 415. The first rotating shaft 412 drives the double cam 411 to rotate forward and backward repeatedly.Thus, it drives the rotation of the connecting plates 410 on the front and rear sides, and further drives the cleaning box 401 on the control board 409 to move back and forth in the front and rear directions. Under the action of the double cams 411, the cleaning boxes 401 on the front and rear sides move in opposite directions. The cleaning box 401 drives the scraper 402 to move, so that the scrapers 402 on the front and rear sides scrape the impurities on the surface of the filter plate 10. Under the action of gravity, the scraped impurities are discharged through the discharge pipe 3, and the vibration is used to facilitate the cleaning of the filtered impurities.

The collision block 426 collides with the metal block 427, and the metal block 427 vibrates and transmits the vibration to the filter box 1, causing the filter box 1 to vibrate. The vibration is transmitted to the surface of the filter plate 10, causing the impurities on the surface of the filter plate 10 to fall off.

[0034] The lower side of the cleaning box 401 is open. A mounting plate 403 is fixedly connected to the inner side of the cleaning box 401. A plurality of nozzles 404 are fixedly connected to the lower side of the mounting plate 403. A connecting pipe 405 is fixedly connected between the cleaning boxes 401 on the front and rear sides.

When cleaning the impurities, the water pump in the water tank 406 is started. Under the action of the connecting pipe 405 and the fixed pipe 407, a plurality of nozzles 404 in the cleaning box 401 spray high-speed water flows onto the surface of the filter plate 10 to wash the impurities on the surface of the filter plate 10 again, improving the cleaning effect. Since the upper side of the cleaning box 401 is open upward at this time, the fallen impurities and sewage are collected through the cleaning box 401. After the cleaning is completed, the motor 2 7 is started to control the cleaning box 401 on the filter box 1 to flip, so that the sewage and impurities inside the cleaning box 401 are discharged. The connecting pipe 405 is a silicone hose and can move with the movement of the cleaning box 401.

[0035] In use, the solution is introduced into the filtration tank 1 through the feed pipe 2, and the filter plate 10 filters the solution. The discharge pipe 3 can discharge the solution. Then, the second motor 7 is started to control the filtration tank 1 to turn over, so that the filtered impurities are quickly discharged, reducing the workload. By starting the first motor 417, the filtration tank 1 is controlled to vibrate, and the scrapers 402 on the cleaning boxes 401 on the front and rear sides are controlled to scrape the impurities on the surface of the filter plate 10. The scraped impurities are discharged through the discharge pipe 3. Then, the water pump in the water tank 406 is started, and the high-speed water flows are sprayed from the spray heads 404 on the front and rear sides onto the surface of the filter plate 10 to facilitate the rapid flushing of the surface impurities. Then, the second motor 7 is controlled to start, and the filtration tank 1 is controlled to turn over to clean the impurities, facilitating subsequent use.
