Abstract

Es wird eine Vorrichtung zum Halten einer Filterfolie oder eines Filtertuches (4), die bzw. das im installierten Zustand in einer Zentrifugentrommel (1) auf einer Stützeinrichtung (3) aufliegt, beschrieben. Die Vorrichtung besitzt ein Schutzsieb (5) und ein Dichtelement (6) mit Dichtlippen, zwischen denen im installierten Zustand sich die Ränder der Stützeinrichtung (3) und der Filterfolie oder des Filtertuchs (4) erstrecken. Im installierten Zustand klemmt das Schutzsieb (5) die Filterfolie oder das Filtertuch (4) und die Stützeinrichtung (3) zwischen den Dichtlippen des Dichtelementes (6) fest. Die Vorrichtung weist ferner mindestens einen Spannring (7) auf, der im installierten Zustand das Schutzsieb (5) radial nach außen presst. Das Schutzsieb (5) ist auf seiner Innenseite mit mindestens einem Vorsprung (8) versehen, der den installierten Spannring in Axialrichtung fixiert. Auf diese Weise wird eine besonders sichere Halterung von Sieb, Filterfolie bzw. Filtertuch und Stützeinrichtung erreicht.

Figure imgaf001
A device for holding a filter foil or a filter cloth (4), which rests on a support device (3) in a centrifuge drum (1) when installed, is described. The device has a protective sieve (5) and a sealing element (6) with sealing lips, between which the edges of the support device (3) and the filter foil or the filter cloth (4) extend in the installed state. In the installed state, the protective screen (5) clamps the filter foil or the filter cloth (4) and the support device (3) between the sealing lips of the sealing element (6). The device further comprises at least one clamping ring (7) which in the installed state presses the protective screen (5) radially outward. The protective screen (5) is provided on its inside with at least one projection (8) which fixes the installed clamping ring in the axial direction. In this way, a particularly secure mounting of sieve, filter foil or filter cloth and support means is achieved.
