Product Description

Product Description

Automatic backwash filter is a kind of self-cleaning filter that consists of multiple stainless steel filer elements and can continuously perform filtration for 24 hours.


It can effectively filter out solid particle contaminants from various water and low-viscosity liquids like rolling emulsions to make the liquid cleanliness meet the system operation and downstream process requirements and protect key downstream equipment. It is widely used in oil & gas, metallurgy, marine filtration systems, water treatment, Pulp & paper and other industries.

 

 

Work Principle

 

The unfiltered liquid flows into the automatic backwash filter from the inlet , half of the liquid flows through the central distribution tube, moves towards the top of the filter and enters filter elements from the top . The other part of the liquid flows into filter elements directly from the bottom of the filter . The unfiltered liquid enters filter elements from the upper and lower ends at the same time and flows out from the outlet after filtering .

When the pressure drop or time reaches the preset value , the automatic backwash procedure is triggered. The gear motor drives the back-flushing rotation arm 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 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 . The washed down impurities are discharged through the sewage pipe.
