Abstract
A filtration device consists of a rotor system (2) which is mounted so that it can be driven to rotate about a horizontal axis (5) in a basin (1) containing a liquid bath, said rotor system consisting of three arrangements (15), for example, each comprising a filter disk pushed onto the tubular cylinder (17) parallel to the axis (5) and therefore being eccentric. The tubular cylinders (17) are fixedly connected to a hollow shaft (18) extending in the direction of the axis (5) for supporting the rotor system (2), this hollow shaft being supported on both ends in bearing units (6, 7) designed as friction bearings which permit a three-dimensional equalization of angle deviations of the axis of the hollow shaft (18). Each filter disk is assembled from segments made of plastic and produced in one piece with coupling pieces as molded parts formed by the injection molding process, so that the axially aligned segments of the filter disks in the state in which they have been placed on the tube cylinders (17) form a continuous filtrate collecting line (23). This yields a design of the rotor system (2) which is structurally simple and permits inexpensive production.
