The utility model has a simple structure and ingenious design. It can choose whether to rotate the scraper rod 14 to scrape the filter plate 4 according to actual needs, thereby reducing the wear of the filter plate 4 caused by the long-term rotation of the scraper rod 14. After the particle precipitation is scraped off, most of the particle precipitation can be thrown onto the first annular plate 5 under the action of centrifugal force, reducing the impact on the filter plate 4 during the filtering process.
