Filtering plate

Abstract

The invention provides a filtering plate which comprises a main filtering plate, wherein a concave area is arranged on each of the two sides of the main filtering plate to form a filtering chamber; the filtering plate further comprises porous plates; each porous plate is mounted in the corresponding filtering chamber; supporting parts are arranged between each porous plate and the corresponding filtering chamber; a filtrate cavity is formed by each porous plate and the cavity of the corresponding filtering chamber; the optimal range of the diameter of through holes is 1-10 mm; the porous plates can be connected onto the main filtering plate in a bolted connection manner, and can also be welded onto the main filtering plate. The filtering plate is simple in structure, and can be transformed on the basis of the conventional filtering plate; according to the filtering plate, the condition that a filtrate can be prevented from being smoothly discharged because filtering cloth is adhered to the bottoms of the filtering chambers of the filtering plate when pressed by materials is avoided.

Description

Technical field: [0001] The invention relates to a filter plate used in a filter press. Background technique: [0002] Filter press is a common equipment used to filter various water-containing materials. With the continuous improvement of the dehydration rate of materials, the filtration pressure adopted by the filter is also increased correspondingly. In the prior art, in the filter chamber of the filter plate The bottom surface is provided with strip-shaped or column-shaped supports at intervals. The gap between the supports becomes the channel of the filtrate. The filter cloth is directly covered on the supports, and the filtrate chamber is formed between the filter cloth and the filter plate. When filtering, the water in the material enters the filtrate cavity through the filter cloth, and then is discharged along the channel between the supports and through the drainage holes on the filter plate; the filter cloth must bear the extrusion of the material, when the filt...
