Problems solved by technology

[0002] In the existing diaphragm filter plate, in terms of structural design, the four supporting bosses of the diaphragm are a part of the diaphragm and have an integral structure. The four supporting bosses are in contact with the four bosses in the filter plate. When multiple diaphragms When the filter plates are superimposed to squeeze materials, because the diaphragm surface of one diaphragm filter plate touches the filter plate of the adjacent diaphragm filter plate, and so on, the result is: two of the two diaphragm filter plates What the plate forms is not the support force transmission between the filter plate and the support boss surface of the filter plate, but the diaphragm force between the filter plate support boss and the boss, see the attached image 3 ; When the diaphragm filter plate is forced to squeeze the material, especially for the material with a relatively large compression ratio, it will inevitably cause deformation, cracks, fractures, etc. of the filter plate

Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 and 2 . The boss-embedded diaphragm filter plate includes a diaphragm 2 and a filter plate 3, and the production of the diaphragm 2 and the filter plate 3 is the prior art, so it will not be described here. The diaphragm 2 is located on one side of the filter plate 3 , the four supporting bosses of the diaphragm are round holes and the round holes are sealed and sleeved on the four supporting bosses 4 in the filter plate 3 . The four on the back of the round hole are formed with a sealing ring 5 and form a sealing fit with the annular groove on the filter plate. The faces of the four supporting bosses 4 are lower than the faces of the diaphragm 2 . A plurality of single-sided diaphragm filter plates are overlapped, and the supporting convex surfaces of the plurality of single-sided diaphragm filter plates are in contact with the supporting convex platforms of the filter plates.

Embodiment 2

[0011] Embodiment 2: On the basis of Embodiment 1, the groove wall of the annular groove has more than 2 convex rings and is tightly matched with the sealing ring 5 .

Abstract

The invention relates to a boss embedding type diaphragm filter plate which can be kept nondeformable under pressure. The boss embedding-type diaphragm filter plate comprises a diaphragm and a filter plate. The diaphragm is positioned on one surface of the filter plate. Four supporting boss parts of the diaphragm are provided with round holes, and the round holes are hermetically sheathed on foursupporting bosses in the filter plate. The boss embedding-type diaphragm filter plate has the advantages that the boss embedding-type diaphragm filter plate intrinsically avoids the defect in the background technology, namely filter plate supporting boss surfaces and interposed diaphragms among the boss surfaces suffer stresses; direct force transfer among the filter plate supporting boss surfaces among a plurality of single-surface diaphragm filter plates is realized; the filter plate is ensured to be free from deformation, crack or rupture; the service life of the filter plate is greatly prolonged.

Description

technical field [0001] The invention relates to a boss-embedded diaphragm filter plate capable of ensuring that the filter plate is not deformed under pressure, and belongs to the field of diaphragm filter plate manufacturing. Background technique [0002] In the existing diaphragm filter plate, in terms of structural design, the four supporting bosses of the diaphragm are a part of the diaphragm and have an integral structure. The four supporting bosses are in contact with the four bosses in the filter plate. When multiple diaphragms When the filter plates are superimposed to squeeze materials, because the diaphragm surface of one diaphragm filter plate touches the filter plate of the adjacent diaphragm filter plate, and so on, the result is: two of the two diaphragm filter plates What the plate forms is not the support force transmission between the filter plate and the support boss surface of the filter plate, but the diaphragm force between the filter plate support boss ...
