Problems solved by technology

[0003] The disadvantage of this filter material formed by sintering is that the sintering of the grid elements can only be done in batches, which is complex
Another disadvantage is that sinter bonding requires a large contact area to ensure the firmness of the connection between the components
For grid elements this means that the sinter bond occupies a large area of ​​the grid element which cannot be used for filtration

Embodiment Construction

[0059] Figure 1-2 Lattice elements 1 and 2 comprising several warp threads 3 and 4 and several weft threads 5 and 6 are shown respectively.

[0060] Yarns 3 and 5 in grid element 1 have a larger diameter and are more densely interwoven such that grid element 1 has a much larger grid width than grid element 2 .

[0061] Both grid elements 1 and 2 are unlaminated, so that rises are formed at what are referred to as "intersection points" 7 and 8 (numbered here only by way of example) compared to other areas of grid elements 1 and 2 . If the grid elements 1 and 2 are placed planarly on top of each other, the two grid elements will substantially touch each other only in the area of ​​the intersection points 7 and 8, through which the two grid elements can be well connected. The elements are welded together to form the filter material 9 (see image 3 ).

[0062] In this illustrated embodiment, the filter material 9 comprises three layers of stacked grid elements 1 and 2, wherein...

Abstract

In order to develop a filter material composed of stacked grid members, the invention proposes a filter material consisting of two stacked grid members that have a weld joint between them.

Description

technical field [0001] The invention relates to a filter material comprising two grid elements placed one above the other, a filter body and a method for producing a filter material comprising grid elements. Background technique [0002] Filter materials comprising two layers of laminated grid elements are well known in the art. In order to join the individual grid elements with a large surface area, the individual grid elements are sintered in batches for a relatively long time. Thus, the grid elements are closely combined in the mutual contact area, so that the grid elements are firmly combined to form a multi-layer filter material. [0003] A disadvantage of such filter materials formed by sintering is that the grid elements can only be sintered in batches, which is complex. Another disadvantage is that sinter bonding requires a large contact area to ensure the firmness of the connection between the various components. For grid elements this means that the sinter bond ...
