The filter mesh cylinder is provided with a scraper type self-cleaning assembly. The scraper type self-cleaning assembly is driven by a driving member and is used to scrape the inner surface of the filter mesh cylinder. The scraper type self-cleaning assembly comprises a driving rod and a self-cleaning scraper. The driving member is connected to the driving rod, and the self-cleaning scraper is connected to the driving rod. The scraping end of the scraper faces the inner surface of the filter mesh cylinder.
