The second airbag 15 expands and pushes the transmission rod 16 downward. When the transmission rod 16 moves downward, the transmission gear 23 cooperates to drive the rotating shaft 21 and the multiple groups of fixed rods 20 connected to the rotating shaft 21 to rotate. During the rotation process, the fixed rod 20 drives the elastically connected scraper 30 to clean the impurities adhering to the surface of the filter plate 3; When the fixed rod 20 drives the scraper 30 to rotate, a certain amount of impurities will accumulate on one side of the scraper 30, and will be collected into the collection box 24 through the cooperation of the chamfered surface 31 and the through groove 34. When the elastically arranged shock rod 39 moves to the bottom of the arc groove 32, the top of the shock rod 39 will no longer squeeze the third air bag 40, and the gas inside the fourth air bag 45 will be discharged through the support of the third return spring 37. After the shield plate 35 extends from the fourth receiving groove 36, the through groove 34 is blocked to prevent the impurities inside the collection box 24 from being discharged. When cleaning the impurities inside the collecting box 24 , it can be achieved by removing the arc-shaped fixing plate 5 .
