おそれがあるという問題があった。Conventional technology Conventionally, the compression filter plate of a filter press has a base plate and rubber plates placed on both the front and rear sides of the base plate, and at the filtrate outlet of the filtration surface, a pair of front and rear mouthpiece members are attached with bolts and nuts. It was getting worse. However, with this method, it is necessary to select and use expensive mouthpiece members made of non-rusting materials such as stainless steel, titanium palladium, and hastelloy, depending on the type of stock solution to be treated, and the manufacturing cost of the compressed filter plate. In addition to being expensive, there are still concerns about corrosion resistance even with these materials, and
There is a problem in that it takes time and effort to tighten the mouthpiece member, and if the tightening is not sufficient, the compressed fluid may leak from between the rubber plate and the substrate.

スの圧搾濾板。Filter press filter press comprising a substrate (3) and a rubber plate (4) that covers at least one of the front and rear surfaces of the substrate (3) and has a filtrate groove (6) on the filtration surface (5). In the plate, a recess (8) is provided around the filtrate discharge hole (7) of the substrate (3), and a filtrate connected to the filtrate discharge hole (7) is provided at a location corresponding to the recess of each rubber plate (4). A thick-walled fitting part (10) having an outlet (11) and fitting into the recessed part (8) is provided. A sealing protrusion (12) is provided that protrudes outward from the surface, and a sealing protrusion (12) is provided.
On the upper side of 12), an annular groove (13) for escaping the sealing convex portion is provided on the circumferential side of the thick-walled fitting portion (10);
By press-fitting the thick fitting part (10) of the rubber plate (4) into the concave part (8) of the substrate (3), the sealing convex part (1
2) is deformed along the inner circumferential surface of the concave portion (8), and the tip of the convex portion (12) is pressed against the inner circumferential surface of the concave portion (8) due to the elasticity of the material. Press filter plate.
