In the present invention, it is to be understood that the term "length"; "Width"; "Up"; "Down"; "front"; "Back"; "left"; "Right"; "vertical"; "horizontal"; "Top"; "bottom" "inner"; "outer"; "clockwise"; "counterclockwise"; "axial"; "plane direction"; the directional or positional relationship indicated as "circumferential" or the like is based on the directional or positional relationship shown in the drawings, and is only for convenience of description and simplified description, and does not indicate or imply that the device or element referred to must have a particular orientation; constructed and operative in a particular orientation and therefore should not be construed as limiting the invention.
As shown in fig. 1 to 4, a compressed air plate filter press comprises a filter plate 1, a slurry supply pump and a compressed air pump, wherein the filter plate 1 is formed by arranging the filter plate 1 from top to bottom, a filter chamber is formed between the filter plate and the filter plate, a through hole 2 for introducing slurry is arranged on the filter plate 1, the slurry supply pump is communicated with the through hole 2 through a pipeline, a threaded through hole 3 for introducing compressed air is arranged on the side part of the filter plate 1, and the compressed air pump is communicated with the threaded through hole 3 through a pipeline. Compressed air is introduced into the filter press, secondary squeezing is formed through the compressed air, and water in filter residues is completely squeezed to be dry, so that the problem that in the prior art, the filter cake is over-wet and even directly dilute slurry in the filter pressing process due to insufficient pressure is solved.
The surface of the filter plate 1 is provided with grooves 4 for the filtrate to pass through, and the through holes 2 are arranged in the middle of the surface of the filter plate 1. The groove 4 sinks on the surface of the filter plate 1, the four sides of the filter plate 1 are higher than the groove 4, and the periphery of the through hole 2 on the surface of the filter plate 1 is provided with a bulge 5. The compressed air plate filter press also comprises filter cloth, the filter cloth is paved on the surface of the filter plate 1, and the filter cloth is contacted with the four edges of the filter plate 1 and the bulges 5 to support the filter cloth.
