Embodiment 1

[0046] Such as figure 1 and figure 2 As shown, a kind of sewage treatment membrane with high leakage, including filter plate 1, filter trapezoidal plate 2, trapezoidal treatment membrane 3 and filter press plate 4, the top of filter plate 1 is equipped with filter trapezoidal plate 2;

[0047] A trapezoidal treatment membrane 3 is installed on the top of the filter trapezoidal plate 2, and a filter press plate 4 is installed on the top of the trapezoidal treatment membrane 3;

[0048] The outer walls of both sides of the filter platen 4 are equipped with filtering inclined plates 5, and the bottoms of the two groups of filtering inclined plates 5 are all attached to the outer surface of the trapezoidal treatment membrane 3, and the bottom of the filter plate 1 is equipped with a flat treatment membrane 6, and the flat treatment The bottom of the membrane 6 is equipped with a filter stay 7 , and the tops of both sides of the filter stay 7 are attached to the bottom of the fil...

Embodiment 2

[0051] Such as figure 1 , image 3 , Figure 4 and Figure 5 As shown, the tops of the two groups of filter inclined plates 5 are provided with two groups of fitting grooves 8 arranged front and back, and the inner walls of the four groups of fitting grooves 8 are equipped with movable plates 9, and the tops of the movable plates 9 extend out of the fitting In the inside of the groove 8, the backs of the two groups of movable plates 9 are equipped with connecting long plates 10, and the backs of the two groups of connecting long plates 10 are respectively attached to the fronts of the other two groups of movable plates 9, and the bottoms of the connecting long plates 10 are installed. There is a brush assembly 11, and the bottom of the brush assembly 11 is attached to the top of the filtering inclined plate 5.

[0052] Specifically, the setting of the fitting groove 8 can facilitate the fitting of the bottom of the movable plate 9, and then increase the connection between t...

Embodiment 3

[0059] Such as figure 2 , image 3 and Figure 6 As shown, elastic hemispheres 21 are installed on the outer wall of the L-shaped flap 17 away from the filter support plate 7 .

[0060] The bottoms of two groups of L-shaped folding plates 17 are equipped with L-shaped storage board 22, and the inwall of the depression of L-shaped storage board 22 is equipped with elastic club 23, and the outer surface of elastic club 23 is attached to the outer surface of elastic hemisphere 21. combine.

[0061] Specifically, the sewage treatment membrane component is placed in a filter box with L-shaped storage plates 22 installed on both sides, and then the sewage treatment membrane component is applied with a driving force towards the location of the L-shaped storage plate 22, so that the elastic hemisphere 21 and the elastic ball The rod 23 is squeezed, and then shrinks its own thickness at the same time, and then the elastic hemisphere 21 can be fitted between the L-shaped storage pla...

Abstract

The invention discloses a sewage treatment membrane with high leakage, which comprises a filtering flat plate, a filtering trapezoidal plate, a trapezoidal treatment membrane and a filtering pressing plate, and the filtering trapezoidal plate is mounted at the top of the filtering flat plate; wherein a trapezoidal treatment membrane is mounted at the top of the filtering trapezoidal plate, and a filtering pressing plate is mounted at the top of the trapezoidal treatment membrane; filtering inclined plates are mounted on the outer walls of the two sides of the filtering pressing plate, a flat plate treatment membrane is mounted at the bottom of the filtering flat plate, and a filtering supporting plate is mounted at the bottom of the flat plate treatment membrane. By arranging the triangular treatment membrane, impact force can be reduced when sewage flows, meanwhile, the sewage can be subjected to double filtration treatment, and impurity cleaning operation can be carried out on a filtering inclined plate through movement of a brush assembly, and thereby, the probability that air holes are blocked by impurities reserved above the filtering inclined plate is reduced. The treatment membrane and other parts are in a clamping installation state, the disassembly is convenient, and the ultrafiltration membrane has high water permeability.

Description

technical field [0001] The invention relates to the technical field of sewage treatment membranes, in particular to a sewage treatment membrane with high leakage and a preparation method thereof. Background technique [0002] In order to make the sewage meet the water quality requirements for being discharged into a certain water body or reused, it needs to be purified. The impurities and bacteria in the sewage can be filtered through the sewage treatment membrane to achieve the separation and purification of the mixture in the sewage. Purpose. [0003] The defects of existing sewage treatment membranes are: [0004] 1. Patent document CN112973452A discloses an ultrafiltration membrane for sewage treatment, "comprising a housing, a plurality of ultrafiltration membrane components for filtering are arranged in the inner cavity of the housing, and the inner cavity of the housing is sealed A seal for sealing the ultrafiltration membrane assembly is fixed, and the ultrafiltrat...
