Plate type ultrafiltration membrane locking assembly

Abstract

The invention relates to a plate type ultrafiltration membrane locking assembly which comprises a first membrane, a second membrane, a membrane element formed by a screen mesh clamped between the first membrane and the second membrane and lock plates with annular bodies, wherein the membrane element is sleeved to the peripheral surface of each fan-shaped boss on the front face of a lock plate through a punched hole of the membrane element, and another lock plate with the same structure is abut jointed with the lock plate sleeved with the membrane element by the back face; meanwhile, an insert block and a convex post of one lock plate are respectively inserted into an insert block catching groove and a convex post insert hole of another lock plate to be mutually locked; and the lock plates are sequentially connected to form the plate type ultrafiltration membrane locking assembly. The plate type ultrafiltration membrane locking assembly is formed by overlapping two or more lock plates with the same structure, and the lock plates can be arbitrarily and continuously superposed; the lock plates are convenient and quick to assemble and disassemble, the membrane element is convenient to replace and maintain; the interlocking performance is good, and the sealing performance is reliable and stable; and the surface of the membrane is smooth and easy to clean, thus the filtering efficiency and the service life of plate type ultrafilters are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of semipermeable membrane separation devices, in particular to an ultrafiltration membrane module of a plate ultrafilter. Background technique [0002] At present, most of the membrane modules of plate-type ultrafilters on the market are composed of a membrane, a rigid support plate, and a permeate separator placed between the support plate and the membrane. The disadvantages of this membrane module are: it is troublesome to clean the diaphragm; the sealing structure between the periphery of the membrane, the inlet and outlet and the support plate and the partition is complicated, and the sealing is difficult, especially when the diaphragm is repaired and replaced, the module is disassembled and then reinstalled. It is difficult to reset accurately, thus causing leakage and causing a decrease in filtration quality and efficiency. Contents of the invention [0003] The object of the present invention is to...
