Problems solved by technology

[0011] Therefore, from the perspective of improving rigidity, the wall thickness of the existing filter plate is very large, and the weight becomes heavy at the same time
Also, due to the heavy weight, it takes a lot of force to move the multiple filter plates sideways
Moreover, the weight of the filter plate becomes heavier and the wall thickness increases, resulting in a large and expensive filter press as a whole.

Abstract

A filter plate enabling the production of a lightweight and compact filter press at low cost and a method of manufacturing the filter plate. The filter plate (1) comprises a filter plate body (3), a frame member (5), spacers (6) installed on both surfaces of the filter plate body (1), covering members (7) covering the spacers, a filter cloth (8) for filtrating filtrated matters fed to a filtrating chamber, a discharge passage (31) for discharging a filtrate to the outside, and a net (9) for leading the filtrate passed through the filter cloth (8) to the discharge passage (31). When the filtrated matters are filtrated by using the filter press having the filter plate, the plurality of filter plates are stacked on each other and clamped, the filtrated matters are force-fed to the filtrating chamber formed between the filter plates adjacent to each other, and the filtrated matters are separated into a liquid and a solid through the filter cloth. When the plurality of filter plates are stacked on each other, the tip of the covered spacer (6) on one filter plate abuts on the tip of the covered spacer (6) on the adjacent other filter plate through the filter cloth (8).

Description

technical field [0001] The invention relates to a filter plate used in a filter press and a manufacturing method thereof. Background technique [0002] In recent years, there is a tendency for the amount of sludge generated accompanying the treatment of various organic wastewaters to increase. When such sludge is discarded as it is, it causes significant pollution to groundwater, rivers, and the like. Therefore, from the viewpoint of preventing environmental pollution, attempts have been made to separate the sludge into solid dehydrated lumps and filtrate. For dehydrated lumps obtained by separation, for example, recycling and efficient reuse, or reclamation after incineration. On the other hand, for filtrate, for example, it is discharged into rivers after being rendered harmless. As an apparatus for dehydrating the to-be-filtered material, such as sludge, the filter press (pressurized filter apparatus / solid-liquid separation apparatus) shown in FIG. 1 and FIG. 2 was use...
