Problems solved by technology

Since, however, only one side of the filter, ie the membrane side, is heated, there is a high temperature drop in the filter.
Insufficient heating of the filter in the area of ​​the chamber plates when alternating chamber plates and membrane plates are used

Embodiment Construction

[0013] The combined chamber and membrane filter plate 1 is substantially square so as to have approximately the same dimensions in the vertical direction 2 and in the horizontal direction 3 . exist figure 1 One side of the chamber and membrane filter plate 1 shown in has a surrounding fixing groove 4 for fixing on figure 1 Diaphragm 13 not shown. The fastening groove 4 extends along the plate edge 5 surrounding the chamber and membrane filter plate 1 . The plate edge 5 has a thickness in the transverse direction 6 , which extends perpendicularly to the vertical direction 2 and the horizontal direction 3 , which is greater than the thickness of the plate base body 7 surrounded by the plate edge 5 . This is especially true in figure 2 It can be clearly seen in . The combined chamber and membrane filter plate 1 has an outlet opening 8 in each of the four corner regions. A filtrate inlet hole 9 is provided at the center of the central area of ​​the combined chamber and membr...

Abstract

The invention relates to a combined chamber and membrane filter plate (1) comprising a base body (7) and a thickened edge (5) which projects from the base body (7) and surrounds the same, said plate edge comprising a chamber side and a membrane side which opposes the chamber side and carries a membrane which is anchored to the edge (5), at a distance from the base body (7). The invention is characterised by at least one recess (11,15) in the base body (7), which reduces the thickness of the base body (7).

Description

technical field [0001] The present invention relates to a heatable filter plate, namely a combined chamber and membrane filter plate. In this combined chamber and membrane filter plate, one plate side, such as a conventional chamber filter plate, and the other plate side, such as a membrane filter plate, are provided with a membrane arranged in front of the chamber filter plate. If a filter plate stack is assembled from this type of combined chamber and membrane filter plates, a plate side with membranes and a plate side without membranes are always placed side by side. Background technique [0002] The same effect can be achieved with a filter plate stack, which is assembled alternately from chamber filter plates and membrane filter plates. In this type of filter plate stack with alternating filter plates, a chamber filter plate without membranes is arranged next to a membrane filter plate, which has a membrane filter plate on each side of the filter plate Diaphragm. In ...
