Taking the cleaning of the inner wall of the filter screen as an example, in the prior art, a plurality of scraper structures 30 are driven to rotate through a rotating shaft 11, so that the cleaning of waste materials on the inner wall of the filter screen is realized. Under the action of stable pressure, the scraper structure 30 needs to be fully contacted with the inner wall of the filter screen, namely, the scraper structure 30 is in interference fit with the inner wall of the filter screen, so that the waste on the filter screen is ensured to be cleaned. Therefore, each scraper structure 30 is subjected to a greater scraping resistance against the material to be removed and a greater resistance against interference with the filter screen, so that each scraper structure 30 wears faster.

By applying the scraper assembly of this embodiment, at least two scraper structures 30 are installed in a staggered manner, so that at least one scraper structure 30 is in interference fit with the filter screen, and other scraper structures 30 can scrape materials to be removed but have a certain gap with the filter screen, therefore, when the scraper assembly works, the scraper structure 30 in interference fit with the filter screen only cooperates and removes part of the materials to be removed, and the scraper structure 30 in interference fit with the filter screen removes the rest of the materials to be removed, that is, the scraper structure 30 in interference fit with the filter screen reduces the scraping resistance of the scraper structure 30 in interference fit with the filter screen, and removes part of the materials for the scraper structure 30 in interference fit with the filter screen, so that the scraping resistance of the scraper structure 30 in interference fit with the filter screen is also reduced.
