the elastic sheet 45 is matched with the curling part 46, and simultaneously, the flocculent impurities adhered to the bottom of the filter screen 2 are kneaded into strips when passing through the elastic sheet 45 through the larger friction factor of the friction plate and then fall off, so that the dust removal efficiency is further increased, meanwhile, the density of the strip impurities is greater than that of the flocculent impurities, and the impurities are reduced from being re-adsorbed on the filter screen 2 due to lighter weight after falling; the magnetic strip 47 is attracted by the magnetic block 48, so that the attaching degree and the attaching area of the elastic sheet 45 and the filter screen 2 are further increased, and the kneading efficiency of the friction sheet on the elastic sheet 45 to flocculent impurities is further increased; the scraper 49 props against the filter screen 2 and scrapes the filter screen 2, so that the separation efficiency of the impurities kneaded into strips from the filter screen 2 is further increased; the rope 51 is continuously wound through the grooved pulley 54, so that the elastic ball 53 is extruded by the sliding hole 5 when continuously penetrating through the sliding hole 5, and then the scraper 49 resets and rebounds when the elastic ball 53 is separated from the sliding hole 5, thereby further increasing the dust scraping efficiency of the scraper 49 due to vibration.
