Industrial filters are widely used in metallurgy, chemicals, petroleum, paper, medicine, food, mining, electricity, urban water supplies. The filter element uses a high-strength wedge filter, which automatically cleans the filter element by differential pressure control and timing control. When impurities build up in the filter element surface cause the import and export pressure difference increase to the set value, drive the backflushing mechanism. When the back-flushing suction cup and the filter element are positive, the sewage valve is open, at this time the system pressure drainage, the suction cup and the inner part of the filter element appear a relative pressure lower than the pressure of the outside of the filter, forcing part of the clean circulating water from the outside of the filter element into the inner side of the filter, adsorption in the inner wall of the filter element particles with water flow into the sewage tank and discharge from the sewage valve. The specially designed filter causes a jet effect inside the filter element, and any impurities are washed away from the smooth inner wall. When the filter import and export pressure difference returned to normal or timer set time to end, the whole process, the material flow, anti-wash water consumption is less, to achieve continuous, automated production.
