The continuous casting water system and blast furnace introduced by modern metallurgical enterprises in my country Water system, high-pressure water descaling system for hot rolling, emulsion system, closed water circulation system, and liquid media filtration system all use a large number of self-cleaning filters.

How to clean the automatic self-cleaning filter? Compared with ordinary filters, self-cleaning filters have the function of automatic sewage discharge. For example, ordinary filters intercept impurities through the filter screen, which requires us to clean them regularly.
