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.

Detailed Description
The technical solution of the embodiment of the present invention is described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the preferred embodiment of the present invention, not all embodiments; based on the embodiment of the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
as shown in fig. 1 and 2, a sealed mosaic filter plate comprises a filter plate body 1, wherein the width of a sealing surface 2 is properly increased on the basis of the original filter plate body 1, and the distance between a concave dovetail groove 3 and the edge of the filter plate is reasonably arranged, so that the filtering area of the filter plate is maximized, and the filter plate is not damaged by the plate edge when being squeezed; materials enter each chamber through a filter plate feeding hole 7 under the pressure of a material conveying pump, and filtrate and washing liquid are discharged and enter through the corner holes 4; the center holes of the two pieces of filter cloth are sewn, wherein one piece of filter cloth passes through the feed hole of the filter plate and is lapped on the surface of the filter plate, the other piece of filter cloth is lapped on the surface of the filter plate in the same way, the edges of the two pieces of filter cloth are rolled into a rubber strip or a rope to form a cylindrical seam, and the cylindrical filter cloth groove 5 is embedded by tapping with a hammer, so that the filter cloth and the filter plate are fixed without being deformed and folded under the influence of external force; the filter cavity inclined plane 6 is contacted with the filter cloth, when materials are filtered, a part of the filter cloth is supported, and the filter cloth is prevented from being damaged by side cutting due to direct load bearing of the filter cloth; the surface of the supporting point 8 is flush with the sealing surface, so that the pressure transmission performance of the filter plate is enhanced, the pressure transmission between the edge and the middle part of the filter plate is uniform, and the service life of the filter plate is prolonged; the structure of the angle hole dovetail groove 9 is the same as that of a concave dovetail groove, and sealing rubber strips made of the same materials and in the same shapes are embedded, so that the angle hole sealing position and the four-side sealing surface are positioned on the same plane, and a tight peripheral seal is formed.
