Abstract

Filter plate with a central working surface and with a plate frame framing the working surface in the manner of a rim and having an increased material thickness compared to the working surface in such a way that the plate frame projects vertically from the plane of the working surface at least on one side, wherein the central working surface and/or the plate frame and/or subassemblies or add-on parts installed in the working surface or in the plate frame have at least two regions with a different material filling density of an identical material.

Claims (22)

1 . A filter plate with a central working surface and with a plate frame framing the working surface in the manner of a rim and having a material thickness which is increased in comparison with the working surface in such a way that the plate frame projects vertically from the plane of the working surface at least on one side,

characterized in that

that

the central working surface and/or

the plate frame and/or

assemblies or attachments built into the working surface or plate frame

have at least two areas with different material filling density of an identical material in such a way that areas with high strength are densely filled with material, i.e. have a high material filling density, while other areas have only a lower material filling density;

wherein different areas in the central working surface and/or in the plate frame and/or assemblies or add-on parts built into the working surface and/or into the plate frame and/or assemblies or add-on parts built onto the plate frame have different geometric filling patterns for realizing a different material filling density.

2 . The filter plate according to claim 1 , characterized in that:

the material filling density of adjacent areas continuously merges smoothly into one another.

3 . The filter plate according to claim 1 , characterized in that:

the areas with different material filling density have different stiffness and/or strength.

4 . The filter plate according to claim 1 , characterized in that:

the central working surface and/or the plate frame

and/or assemblies or add-on parts installed in the working surface or in the plate frame consist of a plurality of layers of different material filling density lying one above the other and/or next to one another.

5 . The filter plate according to claim 1 , characterized in that:

at least one bore passes through the central working surface

and/or the plate frame in the manner of a channel, and in that the outer walls of the plate frame and a bore casing have a higher material filling density than an intermediate layer lying between them.

6 . The filter plate according to claim 5 , characterized in that:

the outer walls of the central working surface and/or of the plate frame have a higher material filling density than the bore casing.

7 . The filter plate according to claim 1 , characterized by:

different mechanical and physical properties of different areas in the central working surface and/or in the plate frame and/or in the attached or installed assemblies or add-on parts with different material filling densities.
