FIELD: process engineering.
SUBSTANCE: proposed filter comprises corrugated membrane 2 and deflecting plate 3A, 3B fitted on the shaft. It is secured on elements and may revolve. Deflecting plate 3A, 3B extends from suspension to folds and features free end 9A, 9B running between membrane folds to clean the latter on moving along their line. Said deflecting plate is made up of flexible plate 10A, 10B and comprises its part arranged between suspension 4 and free end 9A, 9B with width, in direction perpendicular to deflecting plate travel, decreasing depending upon distance from suspension 4.
EFFECT: higher stiffness of deflecting plate to allow efficient cleaning of impurities.
