AUTOMATIC REGENERATED FILTER Russian patent published in 2016 - IPC B01D29/52 B01D29/66 

FIELD: treatment plants.

SUBSTANCE: invention relates to filtration of fluids and can be used in various industries, where cleaning fluids of mechanical impurities in wide range of subtleties filtration in continuous process of filtration is required. Filter comprises casing with connected contaminated medium inlet unions, output of purified medium, output of circulating medium, drain union, cover with drive support and gear motor installed on it, air outlet union, shaft-manifold, central stepped shaft on which there is positioning unit representing star with teeth, located inside housing filtration elements with inner filtration surface. Housing is arranged horizontally, its inner chamber is divided by welded support tube plate with through holes into two cavities: contaminated medium cavity and purified medium cavity. Each cavity has air outlet and drain unions, located in one vertical plane. Ends of casing are closed with covers. One of them is removable, protecting said inner part of filter from mechanical damages. Filtration elements on one side are fitted in through holes of support tube plate and are pressed by clamping plate with through holes, which diameter is less than diameter of through holes of support grid and diameter of filtering elements, and on other side are fitted in through holes of tube plate fixed on internal supporting flange. Inner cavities of filtering elements are closed with blind pressure plate, sealing pure medium cavity from outer space.

EFFECT: technical result is fast replacement of spent filter elements.
