Pneumatic Scraper Type Self-cleaning Filter by mechanical scraping ways to automatically remove the particulate impurities of filter element surface , and it is a continuous online single-filter filtration, no consumable, no frequent manual cleaning job, be suitable for a filtration of general or high viscosity liquid . It is easy to be blocked when the traditional manual filter is used for the filtration of viscous materials and soft impurities, the customers are forced to select a large filter or frequently backwashing, the cost of investment is large, heavy workload, and a serious waste of materials. Pneumatic scraper type self-cleaning filter can easily solve such these problems, and, it can always keep the filter element clean, a high impurity for exhausted slag liquid, the waste material is small. Pneumatic scraper self-cleaning filters are replacing traditional manual filters in many fields because of their significant technological advantages and low life-cycle cost. Such as vibrating screens, bag filters, basket filters, and some backwash self-cleaning filters, etc.
Process of Filtration
Liquid inflow from the inlet, with a disc-shaped scraper blade close to the inner surface of the filter element, stopping at the top filter element, the liquid medium outflow from the inner surface to the outside surface of the filter element, the impurities are trapped in the inner surface of filter element, the liquid medium outflow from the outlet. As time goes by, the impurity increases gradually, the pressure difference rises,
