Problems solved by technology

Due to the small size of the hard disk membrane unit, it is difficult to meet the sewage project with a daily treatment capacity of more than 500 tons. Since the end plates at both ends of the module are round, it is very cumbersome to form a membrane stack device, which is not conducive to the market promotion of the product and cannot meet the needs of the sewage treatment field.

Embodiment 1

[0051] Embodiment 1: as Figure 1~Figure 7 As shown, a small square film membrane assembly includes a permeate water conduit 1 provided with a permeable hole 11, a soft film 2 and a locking piece 3 arranged on the permeate water conduit 1 interlaced, and the permeate water End plates 4 at both ends of the conduit 1;

[0052] The soft film 2 includes a first diaphragm 21, a second diaphragm 22 and a supporting sheet 23 arranged between the first diaphragm 21 and the second diaphragm 22, the first diaphragm 21 and the second diaphragm 22 A first runner cloth 24 is arranged between the supporting sheets 23 , and a second runner cloth 25 is arranged between the second diaphragm 22 and the supporting sheet 23 .

[0053] The locking piece 3 is composed of an inner locking ring 31 close to the outer wall of the permeating water conduit 1, an outer locking ring 32 far away from the outer wall of the permeating water conduit 1, and an outer locking ring 32 disposed between the inner l...

Embodiment 2

[0057] Example 2: Reference Figure 1~Figure 7 , a small square film assembly, the difference from Embodiment 1 is that: the support sheet 23 of the film 2 is provided with a pressure regulating channel, and the film is provided with a joint at the pressure regulating channel, so The joint part is a part formed by ultrasonic welding of the first membrane, the second membrane, the first flow channel cloth and the second flow channel cloth.

Abstract

The invention discloses a small square soft sheet membrane module, belonging to the technical field of water treatment filtering mediums. The small square soft sheet membrane module comprises a percolating water guide pipe provided with water permeable holes, soft sheet membranes and locking plates which are arranged on the percolating water guide pipe in a staggered way, and end plates respectively arranged at the two ends of the percolating water guide pipe, wherein through holes, through which the percolating water guide pipe can pass, are respectively formed in the middle parts of the locking plates; the inner wall of each locking plate is provided with a convex part, and the convex parts enable a percolating water flow channel to be formed between the percolating water guide pipe and the inner walls of the locking plates. The small square soft sheet membrane module is provided with the stable percolating water converging flow channel, thus being basically constant in outlet water resistance and stable in permeant flux; furthermore, sealing rings arranged in the locking plates do not fall off, so that a membrane filtration component structure which is stable in all the directions and firm in sealing can be formed.

Description

technical field [0001] The invention relates to the technical field of water treatment filter media, in particular to a small square film membrane assembly. Background technique [0002] Ultrafiltration membrane technology is currently one of the most common and most convenient and effective technologies in the field of wastewater treatment. It has many advantages such as simple structure, convenient operation, good effluent quality, and low investment cost. [0003] The applicant once applied for an invention patent with the application publication number CN 101700471 A in 2009, which disclosed a hard disk plate type ultrafiltration membrane locking assembly, including a filter membrane element and a locking piece, which improved the overall stability of the filter membrane element. Toughness, while increasing the filtration area, reducing the filtration resistance, and also has the advantage of simple assembly. [0004] in engineering applications. Due to the small size ...
