Abstract

The utility model relates to a diaphragm filtering plate, with the structural key points that the diaphragm is tabled on the filtering plate. A feed inlet and a discharging opening of the filtering plate are communicated by a passage. A nesting is embedded at the discharging opening, and the opening in the wall of the nesting is communicated with the passage. A gland is covered on the diaphragm and reelingly connected with the internal wall of the nesting. The utility model has the advantages that the setting of the internal nesting of the discharging opening of the filter plate and the design of the gland on the diaphragm effectively avoids the defection that the diaphragm around the discharging opening of the diaphragm filter plate is washed out by the liquor, solving the problem that the people want to solve for years but is incapable of being solved.

Description

Embedded filter plate with diaphragm

The utility model relates to a kind of membrane filter plate, is mainly used in various suspension dehydration techniques fields such as dyestuff, inserts, stearate, kaolin, coal ore, chemical industry, environmental protection, smelting, food, beverage, pectin, medicament preparation.

Background technology of the present utility model: 1. WO92/21423 and US.A3656622, a kind of structure of membrane filter plate is disclosed, this membrane filter plate only relates to the integrated structure of barrier film and filter plate, but the deficiency that the barrier film around the discharging opening is gone out by feed liquid in the unresolved membrane filter plate.2. CN2231126Y and CN2149240Y are disclosed is to be provided with the plug-in fixed mechanism between each two adjacent plate, the inner sealed air chamber that forms of van-type intermediate plate and diaphragm plate, and air chamber communicates with pressure hole, suction nozzle.Not enough point: do not solve the deficiency that the barrier film around the discharging opening is gone out by feed liquid in the membrane filter plate.3. CN2339281Y is the membrane filter plate of the disclosed a kind of chimeric connection of the applicant, and related feature is the connected mode of barrier film and filter plate, and to the problem that the barrier film around the discharging opening in the membrane filter plate is gone out by feed liquid, does not then relate to.

Purpose of design of the present utility model: avoid the weak point in the background technology, design and a kind ofly can avoid the deficiency that barrier film is gone out by feed liquid around the discharging opening in the membrane filter plate effectively.

Design of the present utility model: the present invention is on the basis of existing membrane filter plate, realizes by the improvement to the manufacture craft of its discharging opening and structure.Purpose solves the deficiency that the barrier film around the barrier film discharging opening that exists in the background technology is easily gone out the filter plate embeded slot, caused membrane filter plate to work by band binder liquid, to guarantee the operate as normal of membrane filter plate.Its technical scheme: 1. embedded filter plate with diaphragm, barrier film (2) is entrenched on the filter plate (1), be communicated with by passage (3) between charging aperture in the filter plate (1) and discharging opening, discharging opening is embedded with nested (6), material mouth in its nest wall communicates with passage (3), and gland (8) is pressed in barrier film (2) and upward and with the inwall of nested (6) spins.2. the preparation method of embedded filter plate with diaphragm, be provided with passage and once molding formed or injection mo(u)lding between charging aperture in the filter plate and discharging opening, the plug screw sealing is adopted in the pumping mode hole that is positioned at the charging aperture sidepiece, nested direct mold pressing or be injection-moulded in the discharging opening of filter plate, material mouth in its nest wall communicates with passage, and gland is pressed on the barrier film and spins with nested inwall.

The utility model is compared with background technology, the filter plate discharging opening is nested with inlays setting with the barrier film upper press cover, avoids the deficiency that barrier film is gone out by feed liquid around the discharging opening in the membrane filter plate effectively, has solved that people want to solve for many years and the difficult problem that not have solution.

1～5 pair of the utility model is done with narration in conjunction with the accompanying drawings.

Embedded filter plate with diaphragm, barrier film 2 are entrenched on the filter plate 1, are communicated with by passage 3 between charging aperture in the filter plate 1 and discharging opening, and it is nested 6 that discharging opening is embedded with, and the material mouth in its nest wall communicates with passage 3, and gland 8 is pressed on the barrier film 2 and spins with nested 6 inwall.Rib-loop and material mouthfuls 9 in nested 6 inwall has have outer rib-loop and are complementary with nested interior rib-loop on gland 8 tegmental walls.Nested 6 is that flat cover is overlapped or milled to interior hexagonal.The manufacture craft of barrier film and filter plate, material and structure are prior art, no longer are described herein at this.

The preparation method of embedded filter plate with diaphragm, be provided with passage and once molding formed between charging aperture in the filter plate and discharging opening, the plug screw sealing is adopted in the pumping mode hole that is positioned at the charging aperture sidepiece, and in the nested discharging opening that directly is embossed in filter plate, the material mouth in its nest wall communicates with passage.Nested 6 and gland 8 adopt hard prepared materials (as stainless steel, copper, steel) to make
