Inner Scraper Self-Cleaning Filter without Introducing Other Impurities

The scraper self-cleaning filter is specially designed for viscosity liquid filtration. It can automatically remove particles and impurities on the inner surface of the filter screen through mechanical scrapping. It allows for continuous online filtration and is suitable for places where no additional substance for back washing can be introduced. We offer both inner scraper self-cleaning filters and outer scraper self-cleaning filters to meet a variety of challenges you may encounter in industrial production.

An inner scraper self-cleaning filter is a kind of self-cleaning filter that is designed to remove impurities on the inner surface of the filter screen through scraper rotation driven by a motor or air cylinder. 

Both stainless steel sheet scrapers and stainless steel brush scrapers are available.

Applications:

Traditional manual filters are frequently clogged when filtering viscous materials and soft impurities, self-cleaning filters can easily solve such problems and always keep the filter element clean. As a result, self-cleaning filters can replace traditional manual filters in many fields.

• Fine chemicals. Paint and ink filtration, softened glycol wastewater filtration, adhesive filtration;

• Food & beverage. Waste oil recovery filtration, fermented broth filtration, chocolate slurry filtration, honey filtration;

• Water treatment. Surface sewage filtration, backwater filtration, landscape water filtration, farm irrigation water filtration, cooling water filtration;

• Marine filtration system. Seawater desalination filtration;

• Oil & gas. Well-completion filtration;

• Pulp & paper. Starch slurry filtration, coating filtration;
