Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a multi-layer ultrafiltration membrane water treatment device. Background Technique

[0002] The ultrafiltration membrane is a semi-permeable membrane with fine filtration ability, usually made of polymer materials. This membrane allows small molecules and solvents to pass through under pressure, while retaining macromolecules, suspended solids and microorganisms. The working principle of the ultrafiltration membrane is to separate substances of different sizes and charges by the combined action of mechanical sieving and electrostatic repulsion. When the water to be treated passes through the ultrafiltration membrane under a certain pressure, water molecules and small molecule solutes (such as salts) can pass through the membrane smoothly, while larger molecules (such as proteins, bacteria, viruses, suspended particles, etc.) are blocked on one side of the membrane, so as to achieve the purpose of purification, concentration or separation.

[0003] By searching, it is found that CN214809887U discloses a multi-layer ultrafiltration membrane water treatment device, including a housing, and a central shaft is fixedly installed inside the housing. The multi-layer ultrafiltration membrane water treatment device of the utility model can firmly install the ultrafiltration membrane body by setting a sliding rod and a sliding groove, and at the same time, it is relatively convenient to disassemble and replace the ultrafiltration membrane body, which is convenient for users to use better. By setting the ultrafiltration membrane body, the second ultrafiltration membrane and the third ultrafiltration membrane, the filtration effect can be significantly enhanced, and the ultrafiltration membranes of different layers do not affect each other. Even if the membrane of a certain layer of ultrafiltration membrane cracks, it will not affect the filtration effect of the whole device. By setting a partition plate, the ultrafiltration membrane body, the second ultrafiltration membrane and the third ultrafiltration membrane can be installed in layers, so that each layer of ultrafiltration membrane maintains a stable state during operation. At the same time, adding support columns is also to improve the stability of the overall device and stabilize the structure of the overall device. The overall device has a simple structure and is relatively convenient to install and disassemble.

[0004] However, when disassembling the ultrafiltration membrane body for cleaning, the entire housing needs to be opened, and then the sliding rod and the sliding groove need to be separated before the ultrafiltration membrane body can be replaced, and the process is still relatively cumbersome.

[0005] Secondly, when the water pressure is unstable, the ultrafiltration membrane body is prone to rupture, thus affecting the service life of the whole water treatment device. Content of the Utility Model

[0007] To achieve the above object, the present utility model provides the following technical solutions: A multi-layer ultrafiltration membrane water treatment device includes a filtration mechanism and a pressure stabilizing mechanism. A communication pipeline is provided between the filtration mechanism and the pressure stabilizing mechanism. One end of the filtration mechanism away from the communication pipeline is fixedly communicated with a water outlet pipe, and one end of the pressure stabilizing mechanism away from the communication pipeline is fixedly communicated with a water inlet pipe, and a valve is provided on the water inlet pipe.

[0008] The filtration mechanism includes a cylindrical outer shell, a semi-circular plate, a first extension plate, a second extension plate, fixing bolts and an ultrafiltration membrane filtration disc.

[0015] Beneficial effects

[0016] The utility model provides a multi-layer ultrafiltration membrane water treatment device, which has the following beneficial effects:

[0017] 1. For this multi-layer ultrafiltration membrane water treatment device, by removing the fixing bolts, the restriction on the semi-circular plate can be released, and then rotating the semi-circular plate can open the clamping groove. At this time, the ultrafiltration membrane filter disc can be easily taken out from the annular groove.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a multi-layer ultrafiltration membrane water treatment device, including a filtration mechanism 1 and a pressure stabilizing mechanism 2. A communication pipeline 3 is arranged between the filtration mechanism 1 and the pressure stabilizing mechanism 2.

[0026] The filtration mechanism 1 includes a cylindrical outer shell 7, a semi-circular plate 8, a first extension plate 9, a second extension plate 10, a fixing bolt 11 and an ultrafiltration membrane filter disc 12.

Annular grooves 14 are provided on the inner sides of the cylindrical outer shell 7 and the semi-circular plate 8, and the ultrafiltration membrane filter disc 12 can be fitted and clamped with the annular groove 14. The first extension plate 9 is fixedly connected to the end of the semi-circular plate 8, and the second extension plate 10 is fixedly connected to the outer surface of the cylindrical outer shell 7. Corresponding threaded holes are provided on the surfaces of the first extension plate 9 and the second extension plate 10, and the fixing bolt 11 is fixedly installed in the threaded hole. By removing the fixing bolt 11, the restriction on the semi-circular plate 8 can be released, and then the semi-circular plate 8 can be rotated to open the clamping groove 13. At this time, the ultrafiltration membrane filter disc 12 can be easily taken out of the annular groove 14. Compared with the prior art, the disassembly of the ultrafiltration membrane filter disc 12 is simpler, which provides convenience for the cleaning and replacement of the ultrafiltration membrane filter disc 12.

[0027] The number of the semi-circular plate 8, the first extension plate 9, the second extension plate 10, the fixing bolt 11 and the ultrafiltration membrane filter disc 12 is at least three, and they are equidistantly distributed on the cylindrical outer shell 7. By arranging a plurality of semi-circular plates 8, first extension plates 9, second extension plates 10, fixing bolts 11 and ultrafiltration membrane filter discs 12, multi-layer filtration can be realized, and the water purification effect can be improved.

[0028] The ultrafiltration membrane filter disc 12 includes a rubber support ring and an ultrafiltration membrane body. The ultrafiltration membrane body is fixedly connected to the inner wall of the rubber support ring. The upper end of the semi-circular plate 8 is fixedly connected with a first rubber pad 15, the inner wall of the semi-circular plate 8 is fixedly connected with a second rubber pad 16, and the inner wall of the clamping groove 13 is fixedly connected with a third rubber pad 17. By setting the rubber support ring, the first rubber pad 15, the second rubber pad 16 and the third rubber pad 17, leakage at the joints of the cylindrical shell 7, the semi-circular plate 8 and the ultrafiltration membrane filter disc 12 can be effectively avoided.

[0029] The voltage stabilizing mechanism 2 includes a voltage stabilizing box 18, a support frame 19, an electric telescopic rod 20, a piston push-pull plate 21, a limit baffle 22 and a trigger assembly 23.

By setting the voltage stabilizing mechanism 2, when the water pressure is high, the airbag 24 and the spring 25 will be compressed, which can drive the pressing block 26 to move. When the water pressure reaches a certain value and causes damage to the ultrafiltration membrane filter disc 12, the pressing block 26 will touch the contact switch 27, thereby controlling the electric telescopic rod 20 to contract. Using the contraction of the electric telescopic rod 20 can drive the piston push-pull plate 21 to move upward, thereby increasing the water storage volume in the voltage stabilizing box 18, and then reducing the water pressure, effectively avoiding the rupture of the ultrafiltration membrane filter disc 12 due to too high water pressure, and improving the service life of the entire device.

[0030] Working principle: When the multi-layer ultrafiltration membrane water treatment device is in use, multiple ultrafiltration membrane filter discs 12 can be clamped and installed in the annular groove 14, and then the semi-circular plate 8 is rotated and the semi-circular plate 8 is clamped into the clamping groove 13. At this time, the first extension plate 9 and the second extension plate 10 will fit together, and then the fixing bolt 11 is screwed into the threaded hole to relatively fix the first extension plate 9 and the second extension plate 10, so that the semi-circular plate 8 and the ultrafiltration membrane filter disc 12 can be fixed. Water enters from the water inlet pipe 5, is filtered by the ultrafiltration membrane filter disc 12, and then discharged from the water outlet pipe 4, so as to realize the filtration of water. When it is necessary to disassemble the ultrafiltration membrane filter disc 12, the valve 6 on the water inlet pipe 5 can be closed, and then the fixing bolt 11 is disassembled, which is convenient to disassemble and clean the ultrafiltration membrane filter disc 12.
