The main improvement of the utility model lies in facilitating the cleaning of solid impurities accumulated on the top of the filter plate. Figures 1 to 5As shown, when the filter plate on the filter frame 2 needs to be cleaned of impurities, the push-out electric push rod 602 is started to drive the scraper 601 to push the impurities on the filter plate out of the push-out port 8, and then the impurities fall into the collection frame 3 through the sedimentation tank 1, and the cleaning of the impurities is completed.

[0025] The scraper 601 is arranged on the top surface of the filter plate in the sedimentation tank 1, and the movement of the push-out electric push rod 602 can make the scraper 601 push the impurities on the filter plate to the push-out port 8 and be collected by the collection frame 3, so that the cleaning is simple and convenient, and the push-out process of the scraper 601 can also scrape the impurities attached to the filter plate, so that the cleaning effect of the impurities is good, and the cleaning effect of the filter plate is further improved.
