(57) [Summary] [PROBLEMS] To provide a plastic filter plate for a filter press, in which deformation due to pressurization is reduced without sacrificing a filtration area when performing solid-liquid separation. In a filter plate in which a sealing portion having a wall thickness larger than that of the filtering portion is provided at a peripheral portion of the filtering portion having at least one surface engraved with a vertical groove, the inside of the tapered portion is provided. A filter plate for a filter press, characterized in that a long filtrate passage groove is provided in a row in the inclined direction of the taper portion. [Effect] By engraving the filtrate passage groove near the inner side of the taper portion between the seal portion and the filtration portion of the filtration plate, the strength of the filtration portion where stress is easily concentrated is improved, and the stress generated in the filtration plate is reduced. The effect is reduced and the deformation can be minimized.

ものである。2. Description of the Related Art Conventionally, various types of plastic filter plates incorporated in a filter press are known, and these filter plates are usually provided with filtrate passage grooves for drainage on the surface. It consists of a filter part provided and a thick seal part formed on the periphery, and it is used between pressure plates of a filter press machine by arranging a plurality of sheets in parallel in the vertical direction. At this time, the peripheral portions of the respective filter plates are brought into contact with each other by the pressing device and sealed to form the filter chambers between the filter plates, and the slurry or the like is introduced therein to be filtered under pressure, and the filter plates are filtered after filtration. Is released and the residue is discharged.

すると云う問題がある。Since the filter press machine repeats the above cycle, the filter plate may be deformed due to the differential pressure between the front and back sides of the filter plate which is generated when being pressurized in this cycle. When the force of this deformation is repeatedly received,
When the filtrate passage grooves are engraved in one direction, for example, in the vertical direction, the strength in the groove direction and the direction perpendicular to the groove direction may be compared to the strength in the parallel direction. Get lower. Further, in order to reduce the deformation due to the differential pressure, it is often done to dispose the reinforcing portion having the same thickness as the peripheral sealing portion in the filtering portion, but in this case, only the area occupied by the reinforcing portion is provided. There is a problem that the filtration area is reduced and the filtration efficiency is reduced.
