Outer-scraper Self-cleaning Filter

Liquid enters through the water inlet and flows up to bottom and then flow out through the surface of the filter elements. When the impurities on the surface of the filter element accumulates to a certain amount, the scraper which is driven by electric machinery and equipped with correctors will rotates closely on the filter elements to scrap off the impurities. Then the impurities will be collected in collection chamber. when it collected to a certain amount, the automatic drain valve opens and drain out the liquid containing high concentration of impurities. The liquid after filtration would be recycled or discharged.
