FILTER

摘要

FIELD: cleaning liquids. SUBSTANCE: filter has backing with filter material in form of flat rectangular whose sizes fall within inner size of filter housing, thus forming four hermetic volumes between housing and lateral sides of backing. Each volume is provided with branch pipe located on housing along central axis of symmetry of backing. Upper and lower surfaces of backing and plates mounted on bottom and under cover of filter housing are provided with grooves. Grooves provided on upper surfaces of backing and plate mounted on bottom of housing are perpendicular to grooves made on lower surfaces of backing and plate mounted under cover of filter housing. Construction of filter provides for filtration of liquid at simultaneous cleaning of part of filtering surfaces. EFFECT: enhanced efficiency. 2 cl, 2 dwg
