The utility model provides a technical scheme that aforementioned technical problem adopted is: a filter plate, its characterized in that: the filter plate comprises a filter plate body, wherein a dovetail groove with section shape characteristics is milled on the periphery of a sealing surface on one surface of the filter plate body, and a sealing rubber strip is embedded in the groove; round grooves with the same section shape and characteristics of dovetail grooves are milled around the four-angle holes of the filter plate on one surface (the same surface with the dovetail grooves) of the filter plate body, and adhesive tapes with the same material and shape are embedded; the filter plate body is provided with a filter cloth embedding groove at a certain distance from the dovetail groove on the front and back sealing surfaces, and the filter cloth embedding groove is connected with the inclined surface of the filter cavity.
Furthermore, a certain distance is reserved between the sealing surface on one side of the filter plate body and the edge of the filter plate, a groove with the section shape characteristic of being a dovetail groove is milled by a forming cutter, the dovetail groove is wide at the bottom and narrow at the top, the side surface and the bottom surface of the dovetail groove are connected by adopting an arc, the diameter of a sealing rubber strip is slightly larger than the width of the outlet of the dovetail groove and the depth of the groove, interference fit is adopted, the sealing rubber strip is higher than the sealing plane of the filter plate, and when adjacent filter plates are pressed tightly.
Furthermore, the sealing surface of the filter plate body is the same as the surface of the dovetail groove, a circular groove with the same section shape and characteristic of the dovetail groove is milled around the four-corner hole of the filter plate by adopting a forming tool, and a sealing rubber strip is embedded into the circular groove in interference fit, so that the four-corner hole is ensured not to leak liquid and air when the filter press works.
Furthermore, filter cloth embedding grooves are milled on the positive and negative sealing planes of the filter plate body at a certain distance from the dovetail groove and are formed by one-step processing by adopting a forming cutter, the section of each groove is characterized by being cylindrical, and two spherical convex bodies are arranged in the same plane close to the upper end part of each groove to form a barrier so as to prevent the filter cloth from being pulled out of the groove due to material filling extrusion; one part of the groove is embedded on the sealing plane, and the other part is lower than the sealing plane, is parallel to the sealing plane and is connected with the inclined plane of the filter cavity.
Further, the filter cloth edge of filter plate body is wrapped up in adhesive tape or rope seam and is closed as an organic wholely, inlays in cylindrical recess, and whole filter cloth covers filters the concave surface, and the filter cloth is fixed firm steady, difficult fold, and the material filters evenly.
Furthermore, the sealing surface of the frame of the filter plate body is slightly wide, so that a sealing dovetail groove and a cylindrical filter cloth groove are reasonably arranged, and the maximization of the filtering area is guaranteed.
The utility model provides an airtight filter plate of inlaying has both solved the material and has remained the sealed face of filter plate and lead to sealed not tight, leaks water, gas leakage problem, has innovated the fixed mode of filter cloth on the filter plate again, makes the filter cloth no longer because external force and fold warp, influences the filter effect.
