FIELD: cleaning of liquids and gases and gases from mechanical impurities; various industries and transport. SUBSTANCE: filter has cylindrical filter element whose filtering surface is made on projections and fins of the same height. Double-arm scraper with two rows of brushes is mounted on axle. Flow of liquid running through filter sets scraper in rotation on axle which is axle of rotation of filtering surface on projections. Brushes of scraper clean filtering surface from sediment and clean themselves when get in contact with fins, thus excluding penetration of sediment particles into filtering surface for the second time. EFFECT: extended and reliable operation. |
