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.
A belt-type filter apparatus for removing foreign particles from liquid baths, the apparatus comprising a basin containing the liquid, a filter belt constructed as an endless perforated support belt, a cylindrical drum mounted in the basin so as to be rotatable about a horizontal axis, the cylindrical drum having a cylindrical wall with intake openings, the cylindrical drum having an interior forming a low pressure chamber, the low pressure chamber being in communication with devices for producing negative pressure, and a plurality of guide rollers for guiding the support belt into the basin, around the cylindrical drum over the intake openings of the cylindrical drum and out of the basin, wherein the cylindrical drum comprises a tubular hub, intermediate walls forming radial sector chambers being mounted between an outer wall of the tubular shaft and the cylindrical wall of the cylindrical drum, further comprising a cylindrical shaft, the tubular hub being mounted on the cylindrical shaft, the cylindrical shaft having a wall provided in a lower circumferential portion with liquid inlet openings, and wherein the tubular hub has liquid outlet openings between the intermediate walls, wherein the liquid inlet openings of the cylindrical shaft are positioned such that the devices for producing negative pressure are in communication through a rotary valve-like interaction of the liquid outlet openings of the tubular hub and the liquid inlet openings of the tubular shaft with the sector chambers whose cylindrical wall portions are covered by the support belt.
