[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] Example 1:

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a membrane element unit, including two track mechanisms 3, two membrane boxes 2 slidably disposed on the two track mechanisms 3, at least one membrane curtain 1 disposed between the two membrane boxes 2, and a fixing mechanism 4 detachably disposed on the membrane boxes 2.

[0033] like Figure 1 and Figure 2 As shown, optionally, four membrane curtains 1 are combined into a membrane box 2, and then epoxy resin or polyurethane potting compound is applied to form a membrane element.

[0034] like Figure 3As shown, the membrane box 2 includes a membrane element cavity 21, an arched support 22, a membrane curtain mounting platform 23, an anti-derailment structure 24, a water outlet 25, a slider 26, an arc-shaped mounting and positioning boss 27, a cylindrical fixing boss 28, and a disassembly slot 29, etc.

[0035] The membrane element cavity 21 is formed by a shell, and optionally four cavities are used to install the membrane curtain 1. An arched support 22 is provided between adjacent membrane element cavities 21 to improve stability. The membrane element cavity 21 and the arched support 22 form a membrane box 2 with an arched flow channel structure. The arched flow channel structure design inside the membrane box 2, together with the arched support 22, can provide better structural mechanical support and prevent deformation of the structural components during injection molding, thus enabling the injection molding of the membrane box 2.

[0036] A membrane curtain mounting platform 23 is provided on the inner wall of the inner cavity 21 of the membrane element. The end of the membrane curtain 1 is fixed to the membrane curtain mounting platform 23 by adhesive bonding. In order to improve the connection stability, in some embodiments, bolt connection or snap-fit ​​connection can be added as an auxiliary connection to improve the connection stability.

[0037] To improve the adhesive bonding effect between the membrane curtain 1 and the membrane curtain mounting platform 23, an anti-detachment structure 24 is provided at the membrane curtain mounting platform 23. The anti-detachment structure 24 can be a triangular wedge-shaped anti-detachment platform or other anti-detachment structures, which improves the connection strength between the membrane curtain 1 and the adhesive.

[0038] A water outlet 25 and an arc-shaped mounting and positioning boss 27 are provided at one end of the membrane box 2, and a cylindrical fixing boss 28 is provided at the other end; the water outlet 25 communicates with the inner cavity of the membrane box 2. A disassembly slot 29 is also provided on the cylindrical fixing boss 28.

[0039] A slider 26 is provided on the outer side of the membrane box 2 away from the membrane curtain 1. Optionally, multiple sets of two symmetrical cylindrical or arc-shaped sliders can be provided to improve the stability of the sliding connection.

[0040] like Figure 4 As shown, the track mechanism 3 includes a slide groove 31, a first track fixing groove 32, a second track fixing groove 33, a water outlet slot 34, and an arc-shaped mounting and positioning boss slot 35, etc.

[0041] The slide groove 31 is a slide rail of a certain length. Optionally, two slide grooves adapted to cylindrical or arc-shaped sliders can be provided to improve the stability of the sliding connection.

[0042] One end of the slide groove 31 is provided with a first track fixing groove 32. Since the membrane box 2 can be slidably inserted into the end of the slide groove 31 away from the first track fixing groove 32, optionally, the first track fixing groove 32 is provided on a support. The first track fixing groove 32 and the slide groove 31 can be directly fixedly connected, or detachably connected by plugging, snapping, or bolting. On the support, an arc-shaped mounting positioning boss slot 35 and a water outlet slot 34 are also provided at the first track fixing groove 32. The arc-shaped mounting positioning boss slot 35 is used to accommodate the arc-shaped mounting positioning boss 27, and the water outlet slot 34 is used to accommodate and connect the water outlet 25.

[0043] The other end of the slide groove 31 is provided with a second track fixing groove 33. The second track fixing groove 33 is provided with an insertion hole that is compatible with the slide groove 31. After the membrane box 2 is slidably inserted into the slide groove 31, the membrane box 2 can be prevented from sliding out by installing the second track fixing groove 33.

[0044] like Figure 5 As shown, the fixing mechanism 4 consists of two symmetrical structures, each with an arc-shaped structure. The two arc-shaped structures are aligned and correspond to the cylindrical fixing boss 28 for fixation. The fixing mechanism 4 is provided with fixing bolt holes 41 and fixing positioning blocks 42. The fixing bolt holes 41 connect the two symmetrical structures via bolts. The fixing positioning blocks 42 limit the position of the diaphragm box 2. Optionally, a locking block is provided on the inner wall of the arc-shaped mechanism to cooperate with the disassembly slot 29. When the two arc-shaped mechanisms are aligned and wrap around the cylindrical fixing boss 28, the locking block and the disassembly slot 29 cooperate to achieve axial limiting.

[0045] like Figure 2 and Figure 6 As shown, the membrane curtain 1, membrane box 2, track mechanism 3 and fixing mechanism 4 constitute a membrane element unit 5; multiple membrane element units 5 can be installed in existing membrane module device systems using conventional techniques.

[0046] Example 2:

[0047] like Figure 6 As shown, this embodiment provides a membrane module device system, including a membrane element unit 5, a water collection mechanism 6, an aeration mechanism 7, a frame 8, a hoisting mechanism 9, and a positioning mechanism 10, etc.

[0048] Multiple membrane element units 5 can be installed in the frame 8 by means of snap-fit, plug-in or bolt connection, for example, by means of fixing mechanism 4 to fix membrane element units 5 to frame 8 by bolts; and the water collection mechanism 6, the aeration mechanism 7, the hoisting mechanism 9 and the positioning mechanism 10 can also be installed on the frame 8 by means of snap-fit, plug-in or bolt connection.

[0049] The membrane element unit 5, as the core unit of the membrane module system, acts as the heart of the module, continuously permeating the membrane surface and collecting the permeate into the membrane element's water collection chamber. From there, it flows through the water collection structure 6, sequentially through the water collection branch pipe and then the main water collection pipe, ultimately converging into the main permeate pipeline. The water collection structure 6 acts like the blood vessels of the module, connecting the membrane fiber lumen and the permeate pipeline system. Simultaneously, the aeration structure 7 continuously compresses air through the air inlet, pipelines, main air distribution pipe, trough distributor, pulse aerator, and gas distributor, transporting it into the module. Through the processes of air intake, transport, and aeration, using bubbles of different sizes and gas-liquid two-phase flow, pollutants on the membrane surface are blown off while mass exchange occurs, ensuring the normal functioning of the "heart" (membrane). The frame 8 supports the entire module, acting as its skeleton. During installation, the hoisting mechanism 9 lifts the module to a suitable position using hoisting equipment, and then, guided by the mechanism, installs it in the designated location. The water collection mechanism 6, the aeration mechanism 7, the hoisting mechanism 9, and the positioning mechanism 10 can be implemented using conventional technologies.

[0050] This embodiment mainly designs the membrane element unit 5, which includes two track mechanisms 3, two membrane boxes 2 slidably mounted on the two track mechanisms 3, at least one membrane curtain 1 mounted between the two membrane boxes 2, and a fixing mechanism 4 detachably mounted on the membrane box 2.

[0053] The membrane element cavity 21 is formed by a shell, and optionally four cavities are used to install the membrane curtain 1. An arched support 22 is provided between adjacent membrane element cavities 21 to improve stability. The membrane element cavity 21 and the arched support 22 form a membrane box 2 with an arched flow channel structure. The arched flow channel structure design inside the membrane box 2, together with the arched support 22, can provide better structural mechanical support and prevent deformation of the structural components during injection molding, thus enabling the injection molding of the membrane box 2.

[0054] A membrane curtain mounting platform 23 is provided on the inner wall of the inner cavity 21 of the membrane element. The end of the membrane curtain 1 is fixed to the membrane curtain mounting platform 23 by adhesive bonding. In order to improve the connection stability, in some embodiments, bolt connection or snap-fit ​​connection can be added as an auxiliary connection to improve the connection stability.

[0055] To improve the adhesive bonding effect between the membrane curtain 1 and the membrane curtain mounting platform 23, an anti-detachment structure 24 is provided at the membrane curtain mounting platform 23. The anti-detachment structure 24 can be a triangular wedge-shaped anti-detachment platform or other anti-detachment structures, which improves the connection strength between the membrane curtain 1 and the adhesive.

[0056] A water outlet 25 and an arc-shaped mounting and positioning boss 27 are provided at one end of the membrane box 2, and a cylindrical fixing boss 28 is provided at the other end; the water outlet 25 communicates with the inner cavity of the membrane box 1. The cylindrical fixing boss 28 is also provided with a disassembly slot 29.

[0057] A slider 26 is provided on the outer side of the membrane box 2 away from the membrane curtain 1. Optionally, multiple sets of two symmetrical cylindrical or arc-shaped sliders can be provided to improve the stability of the sliding connection.

[0058] like Figure 4 As shown, the track mechanism 3 includes a slide groove 31, a first track fixing groove 32, a second track fixing groove 33, a water outlet slot 34, and an arc-shaped mounting and positioning boss slot 35, etc.

[0059] The slide groove 31 is a slide rail of a certain length. Optionally, two slide grooves adapted to cylindrical or arc-shaped sliders can be provided to improve the stability of the sliding connection.

[0060] One end of the slide groove 31 is provided with a first track fixing groove 32. Since the membrane box 2 can be slidably inserted into the end of the slide groove 31 away from the first track fixing groove 32, optionally, the first track fixing groove 32 is provided on a support. The first track fixing groove 32 and the slide groove 31 can be directly fixedly connected, or detachably connected by plugging, snapping, or bolting. On the support, an arc-shaped mounting positioning boss slot 35 and a water outlet slot 34 are also provided at the first track fixing groove 32. The arc-shaped mounting positioning boss slot 35 is used to accommodate the arc-shaped mounting positioning boss 27, and the water outlet slot 34 is used to accommodate and connect the water outlet 25.

[0061] The other end of the slide groove 31 is provided with a second track fixing groove 33. The second track fixing groove 33 is provided with an insertion hole that is compatible with the slide groove 31. After the membrane box 2 is slidably inserted into the slide groove 31, the membrane box 2 can be prevented from sliding out by installing the second track fixing groove 33.

[0062] like Figure 5As shown, the fixing mechanism 4 consists of two symmetrical structures, each with an arc-shaped mechanism. When aligned, the two arc-shaped mechanisms correspond to the cylindrical fixing boss 28 for fixation. The fixing mechanism 4 is provided with fixing bolt holes 41 and fixing positioning blocks 42. The fixing bolt holes 41 connect the two symmetrical structures via bolts. The fixing positioning blocks 42 limit the position of the diaphragm box 2. Optionally, a locking block is provided on the inner wall of the arc-shaped mechanism to cooperate with the disassembly slot 29. When the two arc-shaped mechanisms are aligned and wrap around the cylindrical fixing boss 28, the locking block and the disassembly slot 29 cooperate to achieve axial limiting.

[0063] like Figure 2 and Figure 6 As shown, the membrane curtain 1, membrane box 2, track mechanism 3 and fixing mechanism 4 constitute a membrane element unit 5; multiple membrane element units 5 can be installed in existing membrane module device systems using conventional techniques.
