[0034] Reference can be made to Figure 1 , Figure 2 and Figure 4 The present application provides a first embodiment, which provides a membrane group device, comprising: a membrane assembly, a water production coupling component;

[0035] The membrane assembly comprises a membrane box 18, and a water production pipeline arranged on the membrane box 18; the water production pipeline comprises a water collecting square pipe 7 and a water collecting pipe 15, and the water collecting square pipe 7 and the water collecting pipe 15 are hollow inside and communicate with each other; the water production pipeline is used for inputting water into the membrane box 18; the membrane box 18 comprises a membrane frame and a membrane sheet, and hooks or lifting rings are arranged on the membrane frame and can be used as lifting force points, so that a lifting device can lift the membrane assembly and move the membrane assembly up and down; the water production pipeline and the membrane box 18 are prior art, and thus will not be described in detail here;

[0036] Reference can be made to Figure 2 When the membrane assembly moves downward, the membrane assembly is coupled with the water production coupling component to realize the communication between the membrane assembly and the water production coupling component; specifically, the water production coupling component comprises a water production coupling frame 2, a water production support frame 13, a first valve 9 and a second valve 10;

[0037] The water production coupling frame 2 is hollow inside and has open ends at both ends; a water production pipeline 19 is connected to an input end of the water production coupling frame 2, and the water production pipeline 19 is connected to a water production pump; an output end of the water production coupling frame 2 is coupled with an input end of the water collecting square pipe 7 of the membrane assembly to realize the communication between the water production coupling frame 2 and the water collecting square pipe 7; the output end of the water production coupling frame 2 and the input end of the water collecting square pipe 7 of the membrane assembly can adopt a coupling flange, so that no interference or collision occurs during installation, and the water production coupling frame 2 and the water collecting square pipe 7 of the membrane assembly are tightly combined;

[0038] The water production support frame 13 is internally hollow, has an input port at the upper end, and has a plurality of release ports 14 arranged from bottom to top on the side edge of the water production support frame 13. The bottom end of the water production support frame 13 is bolted to the bottom of the pool body, and the upper end of the water production support frame 13 is connected to the water production coupling frame 2 to achieve the support effect of the water production coupling frame 2. The upper end input port is in communication with the water production coupling frame 2, so that the interior of the water production support frame 13 is in communication with the interior of the water production coupling frame 2.

[0039] The first valve 9 and the second valve 10 are arranged at the output port of the water production coupling frame 2 and the input port of the water production support frame 13, respectively. The first valve 9 and the second valve 10 are preferably solenoid valves, and the opening and closing functions are controlled by an external PLC control system. That is, when the first valve 9 is in a closed state and the second valve 10 is in an open state, water can only flow to the water production support frame 13. When the second valve 10 is in a closed state and the second valve 10 is in an open state, water can only flow to the water production coupling frame 2.

[0040] The water production guide pipe 5 is arranged on the upper side of the water production coupling frame 2. The bottom end of the water production guide pipe 5 is fixedly connected to the upper side of the water production coupling frame 2, and the upper end of the water production guide pipe 5 extends upward and is fixed to the pool wall by screwing, riveting or welding. In this embodiment, the number of water production guide pipes 5 is two, which can be adjusted according to actual conditions.

[0041] The water production guide plate 1 is slidably connected to the water production guide pipe 5, and the side of the water production coupling frame 2 close to the water production guide plate 1 is fixedly connected with a first flange 12. The upper side of the first flange 12 is a flat surface 11, and the lower side of the water production guide plate 1 also has a flat surface 11 corresponding to the first flange 12. When the water production pipeline is in communication with the water production coupling frame 2, the upper side of the first flange 12 contacts the lower side of the water production guide plate 1, thereby supporting the water production guide plate 1. That is, after the membrane assembly is lowered into position, the water production guide plate 1 will be clamped with the first flange 12 to ensure firm combination and prevent loosening, thereby improving the working performance and reliability of the membrane assembly.

[0042] In summary, when the staff needs to perform offline cleaning and maintenance, the staff only needs to connect the hook of the lifting device with the hook or the lifting ring on the membrane frame, and then starts the lifting device to lift the membrane assembly from the bottom of the pool for maintenance and cleaning, thereby eliminating the disassembly work; when the membrane assembly needs to be installed back, the staff only needs to lower the membrane assembly through the lifting device. Specifically, the lifting device lowers the membrane assembly, the water production guide plate 1 slides down on the water production guide pipe 5, and when the membrane assembly is lowered to the position, the lower side of the water production guide plate 1 is attached to the first flange 12, the first flange 12 supports the water production guide plate 1, and the input port of the membrane assembly is tightly attached to the output port of the water production coupling frame 2 through the gravity of the membrane assembly, without manual installation; when water production is needed, the operator opens the first valve 9, closes the second valve 10, and then starts the water production pump, which forms a negative pressure in the membrane box 18 through the water production pipe 19. Thus, the inside of the membrane box 18 is under negative pressure, and the outside is under positive pressure. The treated sewage on the outside of the membrane box 18 penetrates into the inside of the membrane box 18 through the small holes on the membrane, and is discharged into the buffer pool through the water production pump, while other macromolecular substances are intercepted on the outside of the membrane, thereby completing the water production work; when online backwashing is needed, the operator opens the second valve 10, closes the first valve 9, and then pours the reagent into the buffer pool, and then starts the water production pump to generate positive pressure in the inside of the water production support frame 13 through the water production pipe 19, thereby guiding the reagent in the buffer pool into the inside of the water production support frame 13 and spraying it out from the release port 14 on the water production support frame 13. Since the release port 14 is arranged from top to bottom on the water production support frame 13, the membrane can be cleaned from top to bottom. In the prior art, the membrane is cleaned by directly guiding the reagent into the water production channel of the membrane box 18 through the water production pipe 19. Since the membrane box 18 is immersed in sewage, the membrane near the bottom is under a large water pressure, so that the reagent cannot be pressed into the membrane from the inside, and the bottom membrane cannot be immersed in the reagent. The release port 14 arranged from top to bottom can achieve sufficient cleaning of the bottom membrane. When regular cleaning is needed, the first valve 9 can be opened and the second valve 10 can be closed to make the reagent pass through the water production pipe and be immersed in the membrane box 18 from top to bottom for regular online immersion cleaning.

[0043] Further, in the embodiment, the plurality of release ports 14 are distributed from bottom to top on the water production support frame 13, and the hole diameters of the release ports 14 gradually decrease from bottom to top. By gradually reducing the hole diameters of the release ports 14, the water head loss of each release port 14 is balanced, the reagent is uniformly distributed, and the cleaning efficiency is improved.

[0044] Further, the input port end face of the water production pipe is formed with a first coupling end face, the output port end face of the water production coupling frame 2 is formed with a second coupling end face, the first coupling end face is inclined, and the second coupling end face is also inclined and adapted to the first coupling end face.

[0046] Further, a sealing member is arranged on the first coupling end surface and the second coupling end surface, the sealing member is made of an elastic material, the sealing member can be a sealing ring, and the sealing member is deformed by being pressed when the first coupling end surface and the second coupling end surface are in close contact with each other, so that the coupling surface can be more tightly sealed to prevent leakage.

[0047] Further, the membrane tank 18 is provided with an aeration system at the bottom, the membrane material is flushed to prevent membrane pollution, and the aeration system includes a blower and an aeration pipe 17, the blower is connected with the aeration pipe 17, and the aeration pipe 17 is provided with small holes.

[0049] The aeration coupling component includes an aeration coupling frame 4, and the input port of the aeration pipeline 17 is coupled with the output port of the aeration coupling frame 4 to realize the communication between the two; that is, the membrane assembly moves upwards to drive the aeration pipeline 17 to move, and the membrane assembly moves downwards to the corresponding position and is coupled with the output port of the aeration coupling frame 4 to realize the communication between the two.

[0050] The input port end of the aeration coupling frame 4 is connected with the output pipe 20 of the blower, the blower is started, and gas is input into the aeration pipeline 17 to perform aeration work.

[0051] The output port end surface of the aeration coupling frame 4 forms a third coupling end surface, and the input port end surface of the aeration pipeline 17 forms a fourth coupling end surface, the third coupling end surface is inclined, and the fourth coupling end surface is also inclined and matched with the third coupling end surface.

[0052] The fourth coupling end surface is inclined from top to bottom to the inside of the aeration pipeline 17, and the third coupling end surface is inclined from top to bottom to the outside of the aeration coupling frame 4; the inclination angle can be any value between 1 degree and 3 degrees, so that when the third coupling end surface and the fourth coupling end surface are coupled, they are more closely fitted, ensuring the sealing performance of the installation, and the third coupling end surface and the fourth coupling end surface are also provided with sealing members made of elastic material, which are deformed when the third coupling end surface and the fourth coupling end surface are in close contact, so that the coupling surface can be more tightly sealed to prevent leakage.

[0053] The aeration pipeline 17 comprises an aeration square channel 8 and an aeration pipe 17 in communication with the aeration square channel 8, the aeration pipe 17 is arranged below the membrane module, and the output port of the aeration pipe 17 is obliquely arranged to the outside of the membrane module.

[0054] The oblique angle of the output port of the aeration pipe 17 is between 10 degrees and 30 degrees, and when the aeration pipe 17 is used for aeration and scrubbing, the membrane module will be subjected to a counteracting force in the opposite direction, which is in the same direction as the required coupling force, so that the coupling is more tightly coupled and has better sealing performance.
