ABSTRACT:
A belt-type filter apparatus for removing foreign particles from liquid baths includes a basin containing the liquid, a filter belt which is constructed as an endless perforated circulating support belt and/or a filter belt fleece which can be wound from a roller and may be placed on the circulating support belt, a low pressure chamber with intake openings arranged in the basin and connected to devices for producing negative pressure, and guide rollers which act on the support belt and/or filter belt fleece in such a way that the support belt and/or filter belt fleece are introduced from the top into the basin, are conducted over the intake openings of the low pressure chamber and are then conveyed toward the top out of the basin. The low pressure chamber is composed of a cylindrical drum which is mounted in the basin so as to be rotatable about a horizontal axis. The interior of the cylindrical drum forms the low pressure chamber and the cylindrical wall of the drum has the intake openings. The support belt and/or the filter belt fleece can be placed on the cylindrical wall.
