Abstract
A filter centrifuge for the separation of solid and liquid components in a suspension in which a filter cloth is used. The filter cloth is inserted in the drum of the centrifuge and is removably fastened at one side about the periphery of an aperture in the drum. The filter cloth is flexible and may be turned inside out to discharge solid materials after the centrifuging operation. To prevent the flexible filter cloth from becoming pressed into the openings of the centrifuge drum by the force of the centrifuging process and the weight of the solid material, a supporting screen is inserted between the inner wall and the drum of the filter cloth. The screen is in the form of longitudinal rods from which the filter cloth is easily removed even if the gaps between the rods are penetrated to a slight extent.

Filter centrifuge for the separation of solid and liquid components found in a suspension, with a centrifugal drum open at one front side, with radial discharge openings, positioned rotatably in a centrifuge housing, and with a filter cloth insertable in the drum, which is removably fastened on the one side to the opening edge of the drum which is tightly sealed by a centrifuge bowl cover, and on the other side to a base plate rigidly joined with the cover in such a way as to leave an open space between them, wherein the centrifugal drum and the base plate are arranged coaxially with one another, and can be set into rotation together, and are movable axially with respect to one another, characterized in that a supporting screen (41) is provided between the centrifugal drum (16) and the filter cloth (22), said supporting screen comprising support elements which are both in direct contact with said filter cloth and oriented exclusively parallel to the center axis of said centrifugal drum and to the axial direction of stripping of the filter cloth.
