Abstract

The invention relates to a screen carrier element (100) for a filtration device comprising at least one screen cavity (101) for arranging at least one filter unit (10) therein, a support tube (15) having cut-outs (15.4) and a plurality of disk filter elements (11), each having a central hub (11.3) with which they are mounted on the support tube (15). A semi-permeable filter medium (11.1) surrounds the hub and is spread out to form a three-dimensional structure. At least one flow channel (11.4) extends in the hub element (11.5) from the main body enveloped by the filter medium (11.1) to the support tube (15), wherein the support tube (15) leads into an outlet channel (102) of the screen carrier element (100). The support tube (15) comprises a bearing section (15.1, 15.2) protruding from beneath the disk filter elements, and said bearing section can be inserted into the outlet channel (102) from the screen cavity (101). The outlet channel (102) is designed as a tapered bore over at least a part of the length thereof, which opens toward the screen cavity (101). At the same time, the bearing section of the support tube (15) has at least one tapered section (15.2) which engages with the…
