FILTRATION DEVICE

摘要

A filtration device comprises a rotor system (2), which is supported in a rotatably drivable manner about a horizontal axis (5) in a basin (1) containing a liquid bath and which comprises for example three arrangements (15), each comprising filter disks that are pushed onto a tubular cylinder (17) that extends parallel to the axis (5), thus eccentrically. The tubular cylinders (17) are rigidly connected to a hollow shaft (18) that is intended to support the rotor system (2) and that extends in the direction of the axis (5). The hollow shaft is supported on both sides in bearing units (6, 7) that are designed as plain bearings and that enable a three-dimensional compensation of angle deviations of the axis of the hollow shaft (18). Each filter disk comprises segments that are made of plastic and that are produced as molded parts having integral coupling pieces in an injection-molding process so that the axially aligned segments of the filter disks form a continuous filtrate collecting line (23) when they are pushed onto the tubular cylinder (17). A design of the rotor system (2) that is simple and that enables low-cost production results.
