    摘要： A screen assembly (10, 52, 80, 81, 82, 85, 91) and a method for fabricating a screen assembly are provided. The screen assembly comprises a thermoplastic screen element (16) including a screen element screening surface (13) having a series of screening openings (86). The screen assembly (10, 52, 80, 81, 82, 85, 91) further comprises a subgrid (14, 18, 58, 60) including a grid framework having grid openings (50, 74). The thermoplastic screen element (16) spans the grid openings (50, 74) and is attached to a surface of the subgrid (14, 18, 58, 60). Multiple subgrids (14, 18, 58, 60) are directly connected to each other to form the screen assembly (10, 52, 80, 81, 82, 85, 91) and the screen assembly is a complete independent structure. The screen assembly (10, 52, 80, 81, 82, 85, 91) has a continuous screen assembly screening surface comprising multiple screen element screening surfaces (13). The thermoplastic screen element (16) is an injection molded piece.

    摘要： A filter media construction wherein at least two layers of a substantially open spacer and at least two layers of a filter media/material are combined in an alternating sequence and coiled around a core to form at least two distinct, continuous or segmented, coil-shaped fluid flow channels that are contiguous but separated by the filter media in the radial direction and extend axially from an inlet side to an outlet side of the filter media construction preventing direct fluid flow between the clean and dirty sides of the filter media construction. The spacer maintains substantially uniform width of the flow channels in the flow direction providing substantially uniform fluid flow. One flow channel is closed to fluid flow at the inlet side forming the clean side and the other flow channel is closed to fluid flow at the outlet side forming the dirty side of the filter media construction.

    摘要： The invention suggests a recess plate (1) designed for use in a filter device for filtering a suspension, the filter device having a stationary head piece and a movable end piece, and a pack including copies of the recess plate (1), having a filter chamber inside the pack, adjoining the recess plate (1), having a first pipe for filling the suspension into the filter chamber, having a filter cloth for collecting a solid content out of the suspension, and having a second pipe for discharging a liquid fraction of the suspension out of the filter chamber as a filtrate, wherein the filter device may be closed before filtering by forcing the end piece in direction of the head piece, and opened after filtering by releasing the end piece, and moving the end piece away from the head piece for removing the filter cake from the filter cloth, and wherein the recess plate (1) has a first surface (9) at the filter chamber and a second surface (10) vis-a-vis the first surface (9), the first surface (9) and the second surface (10) are formed by sheets (2, 3), and the recess plate (1) has a rigid body (15) between the sheets (2, 3). The invention further suggests a method for manufacturing the recess plate (1).

    摘要： Screening members, screening assemblies, methods for fabricating screening members and assemblies and methods for screening materials are provided for vibratory screening machines that incorporate the use of injection molded materials. Use of injection molded screen elements provide, inter alia, for: varying screening surface configurations; fast and relatively simple screen assembly fabrication; and a combination of outstanding screen assembly mechanical and electrical properties, including toughness, wear and chemical resistance. Embodiments of the present invention use a thermoplastic injection molded material.
