Viscous Materials Auto Self Cleaning Filter For Industrial Filtration

 

The unfiltered liquid flows into the automatic backwash filter from the inlet ③ , 50% of the liquid flows through the central distribution tube, moves towards the top of the filter ④ and enters filter elements from the top ⑤ . The other part of the liquid flows into filter elements directly from the bottom of the filter ⑥ . The unfiltered liquid enters filter elements from the upper and lower ends at the same time and flows out from the outlet after filtering ⑦ . When the pressure drop or time reaches the preset value ⑨ , the automatic backwash procedure is triggered. The gear motor drives the back-flushing rotation arm ① to backwash the filter elements in turn while the filtration continues. During backwashing, the upper end of the filter element is covered by the sliding block ② and then the back-flushing valve opens. The differential pressure between the outside of the filter element and back-flushing outlet makes the clean filtrate reversely flush the inner surface of filter element ⑧ . The washed down impurities are discharged through the sewage pipe.
