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: 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 device for filtering a fluid, in particular a liquefied plastic, has a housing with at least one supply channel and having a discharge channel. In the flow path of the fluid at least one screen is arranged in a corresponding screen space in at least one screen carrier, which is supported so as to be displaceable crosswise to the direction of flow. The screen can be brought into connection with the supply channel and with the discharge channel, the screen being formed as an elongate oval or a polygon. The channel splits into two partial supply channels, which open out into the screen space on the dirty side of the screen. The front supply channel, viewed in the screen change direction, opens out into a channel worked into the screen carrier, which channel feeds to the screen space the plastic to be filtered.

Abstract: The invention relates to a device for filtering a fluid, especially a liquefied plastic, said device comprising a housing, a supply channel, a discharge channel and optionally backwash channels. At least two filter elements are arranged in corresponding filter regions in the flow path of the fluid, in a filter carrier which is mounted in such a way that in can be perpendicularly displaced in relation to the direction of flow, said filter elements being able to communication with the supply channel and the discharge channel. Each filter region comprises two supply partial channels which are worked in to the filter carrier or the housing and are oriented away from the filter regions towards the discharge channel. Said discharge channel comprises housing partial channels which flow together to form the discharge channel.

Abstract: The invention relates to a device for filtering a fluid, in particular a liquefied plastic, with a housing with backflush channel and screen carrier and filter element whereby, in order to accelerate and improve the backflush effect, one or more displacement cylinders are provided that guide material removed from the production at adjustable high pressure and speed to the screen to be cleaned from the clean screen side to the dirty screen side, whereby an additional pressure generator ensures constant process pressure.
