Abstract

The present invention relates to a filtration apparatus for filtering and separating solids from liquids comprising at least one liquid-permeable, continuously or intermittently drivable filter belt (3), an intake (4) for charging the liquid/solid mixture to be filtered onto the filter belt (3) in a charging zone (5) and a belt cleaner (6) for removing the solids deposited at the filter belt from a belt section conveyed out of the charging zone (5) in an expulsion zone (7). In accordance with the invention, the belt cleaner (6) has at least one rotatingly drivable brush (8) with which a brush cleaner (9) having a scraper (10) is associated which is arranged in the path of the bristles of the rotating brush (8). The rotating brush efficiently removes the deposited solids from the filter belt, while the scraper (10) of the brush cleaner (9) simultaneously ensures that the dissolved solids do not settle at the brush (8) and clog it. The continuous self-cleaning of the brush (8) is in particular very helpful with sticky contaminants of the liquid to be filtered in order to be able to ensure a permanently efficient, continuous separation of the solids.
