Embodiment 1

[0043] like Figures 1 to 4 In the MBR membrane module shown, the membrane element 410 adopts a square membrane 411 with the same shape and size. The length or width of the diaphragm 411 is 320 mm. The four corners of the diaphragm 411 are all rounded with a radius of 15 mm. The center of the diaphragm 411 is provided with a through hole 411d. A support plate 411f with a thickness of 1.2mm is provided in the cavity 411c of the diaphragm 411. The support plate 411f is a square solid plate, and the four corners of the support plate 411f are respectively provided with chamfers. An assembly hole 411g is provided at the center of the support plate 411f, and the assembly hole 411g is coaxially arranged with the through hole 411d. The length or width of the square support plate 411f is 20mm smaller than the length or width of the square diaphragm 411, so as to reserve the position of the welding scar 411i. The membrane 411 is made by stacking the support plate 411f and the second...

Embodiment 2

[0049] Replace the support rod 100 of Embodiment 1 with a solid rod. On this basis, the structure of the first interface 711 of the guide adapter 710 is adjusted accordingly, so that the flow path formed by the guide gap 430, the matching gap between the seal ring body 421a and the support rod 100 is set on the support The filtered water in the diversion channel on the surface of the rod 100 directly flows into the diversion adapter 710 from the mating surface between the support rod 100 and the first interface 711 of the diversion adapter 710 . The specific method is to set a diversion hole connected to the diversion tube 714 in the side wall of the first interface 711 of the diversion adapter 710 , and connect the diversion hole to the diversion channel provided on the surface of the support rod 100 .

Embodiment 3

[0051] like Figures 9 to 10 As shown, the membrane 411 of the embodiment 1 is improved, specifically, support nets 411h are provided on the inside of the first filter membrane 411a and the inside of the second filter membrane 411b. like Figure 10 As shown, the improved membrane 411 is after stacking the support net 411h, the support plate 411f, the support net 411h and the second filter film 411b sequentially on the first filter film 411a, and then the edge of the first filter film 411a and the second filter film The edges of the two filter films 411b are heat-processed and fused together, and the edges of the support net 411h inside the first filter film 411a and the support net 411h inside the second filter film 411b are preferably combined in the welding scar 411i. The support net 411h can further support the first filter film 411a and the second filter film 411b, and can better prevent the deformation of the diaphragm 411 when used in conjunction with the support plate ...

Abstract

The invention disclose a membrane component used for water treatment. The membrane component comprises a supporting rod, a first end part component, a second end part component, and a membrane core. The membrane core is installed on the supporting cord and is axially positioned between the first end part component and the second end part component; meanwhile, the membrane core comprises multiple membrane parts which are successively connected to the supporting rod in a sleeved mode and are arranged on the supporting rod along an axial direction, the membrane core also comprises sealing devices which are adaptive to the membrane parts. The first end part component and / or the second end part component comprise / comprises a diversion adapter structure, which is used for adaptive connection of every adjacent membrane components so that the delivery outputs between every adjacent membrane components can be communicated. After the installing of the diversion adapter structure, every adjacent membrane components can be connected through the diversion adapter structure, and the communication of delivery outputs of the connected membrane components can reduce the number of corresponding water pipes of the membrane components used for receiving water outside. The membrane component used for water treatment can make the combination of the membrane components much more convenient and can help to improve effective filtration area on unit floor space of the membrane system.

Description

technical field [0001] The invention relates to a membrane module for water treatment, in particular to an MBR membrane module. "MBR" is Membrane Bio-Reactor, which means membrane bioreactor. Background technique [0002] The Chinese patent application document with the publication number CN105617865A (hereinafter referred to as the reference) discloses a novel water treatment membrane stack for high-efficiency filtration, which belongs to the submerged MBR membrane module. Generally speaking, this type of membrane module includes four parts: a support rod, a first end member, a second end member and a membrane core, wherein the support rod is a hollow structure or a solid structure, and the first end member is installed on the support rod The second end member is installed at the other end of the support rod, and the membrane core is installed on the support rod and axially positioned between the first end member and the second end member. In a typical water treatment sit...
