Abstract: A filter element for filtering a fluid comprises a first clamping ring with an outer ring; a first filter disk; a first inner support plate for supporting the first filter disk and which faces to the outside or to an inner flow channel; a second inner support plate provided with recesses; a second filter disk arranged adjacent the second inner support plate; and a second clamping ring which is connected to the first clamping ring by connecting elements. The filter disks and the inner support plates are arranged inside a housing which is formed by the clamping rings, by at least one outer ring and by outer support plates provided with recesses and covering the filter disks on the outside.

Abstract: A filtering device (100) for highly viscous media comprises at least one screen plug (10) which is movably arranged in a screen plug bore (27) of a housing (20) and which has at least one screen cavity (11, 12), a filter element (11.7) lying in said screen cavity. The screen cavity (11, 12) narrows to a funnel section (11.6) in a rear region when viewed in the flow direction, said funnel section opening into at least one screen plug outlet channel that opens upstream of the housing outlet channel (24, 25) in the production position. According to the invention, the screen plug outlet channel comprises an inlet zone (11.1, 11.2), at least one deflecting point (11.3), and an outlet zone (11.2, 12.2). The intake zone (11.1, 12.1) extends from an edge region of the funnel section (11.6), and the outlet zone (11.2, 12.2) is designed as a groove that extends on the outer face of the screen plug (10, 10?) and/or on the inner face of the screen plug bore (27).

Abstract: A cutter head for an underwater granulating installation has a rotor body having a plurality of cutter-retaining arms. Each of the plurality of cutter-retaining arms adjoins the outer circumference, and one cutter element is fastened on each of the plurality of cutter-retaining arms, where the rotor body in the region of each cutter-retaining arm includes at least one receptacle recess configured to receive a fastening element. The cutter element is integrally configured to have a basic body and at least one blade body. The basic body is positioned on a lower bearing face of the rotor body, and the lower bearing face extends up to at least one of the plurality of cutter-retaining arms. The at least one of the plurality of cutter-retaining arms on an upper side is overlapped by the cutter element, and the blade body includes at least one cutting edge molded thereon.

Abstract: A filtering device (100) for high-viscosity fluids has a partial channel (34) in the housing (30) and a displacing piston (40) which can be inserted into the partial channel (34, 35). The displacing piston (40) has at least one inner fluid line (42) that extends from an inlet opening (41) therein to an outlet opening (43) on its circumference. The outer diameter of the displacing piston (40) corresponds to the inside diameter of the partial channel (34, 35). The displacing piston (40) can be positioned, in a production position, with its outlet opening (43) in front of the inlet of the discharge channel (33) into the partial channel (34, 35) and can be retracted to a backflushing initial position within the partial channel (34).

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).

Abstract: A reversing valve (100) for a high-viscosity medium comprises a housing (10) having an inlet opening (23) and at least two outlet openings (21, 22), extending into a valve bore in which is mounted an axially displaceable valve stem (10, 10?). The valve stem comprises a groove by which the inlet opening (23) is alternatively to be connected to one of the outlet openings (21, 22). The groove has an axially extending inflow zone (12) and an axially extending outflow zone (11, 11?). The inflow and outflow zones are connected at both ends to a continuous annular channel by way of connecting channels (13, 14).

Abstract: A filtering device (100?) for the large-area filtration of polymer melts comprises at least: a housing (20; 20?) with at least one inlet channel (23; 71?) and at least one outlet channel (26; 61?) and a filter carrier element (40, 40?), which can be moved longitudinally in relation to a housing bore and has at least one filter insert (10; 10?), which in a production position can be arranged in a filter chamber (24; 24?) between the inlet channel (23; 71?) and the outlet channel (26; 61?) of the housing (20; 20?), wherein the filter insert (10, 10?) has a main element (12, 12?) through which the flow can pass, and from which a fluid stream branches off to multiple individual filter elements (11, 11?) or in which multiple fluid streams from the individual filter elements are combined. The filter insert (10, 10?) is arranged on an end face of the filter carrier element (40, 40?).
