Description

Technical Field

[0001] This utility model relates to the field of filter membrane technology, and in particular to a rotary filter membrane assembly with self-cleaning function. Background Technology

[0002] Membrane filtration technology refers to membrane separation technology driven by pressure. It is an advanced method of deep water treatment. Under certain pressure, when the raw liquid flows through the membrane surface, the numerous tiny pores on the membrane surface only allow water and small molecules to pass through, becoming the permeate. Meanwhile, substances in the raw liquid with a volume larger than the pore size of the membrane surface are trapped outside the membrane, becoming the concentrate. Thus, the purpose of separating and concentrating the raw liquid is achieved.

[0003] In existing technologies, traditional filter membrane modules generally do not have a self-cleaning function. After prolonged use, a large amount of dirt accumulates on the surface of the filter membrane, which affects the filtration effect of the filter membrane module and reduces the service life of the filter membrane. At the same time, it is inconvenient to clean the filter membrane. The traditional cleaning method is to disassemble the filter membrane module and clean the filter membrane. This cleaning method is cumbersome and complicated, wastes time and effort, and reduces the convenience and practicality of the filter membrane module. Utility Model Content

[0024] To achieve self-cleaning of the membrane body 7 during the operation of the filter membrane module, an installation frame 12 is fixedly installed on the outer surface of the membrane housing 1. An installation groove 13 is opened on the outer surface of the membrane housing 1 inside the installation frame 12. An installation plate 14 is slidably connected to the inner wall of the installation frame 12. Several fixing plates 15 are installed on the side wall of the installation plate 14 near the membrane housing 1. The fixing plates 15 are set between two adjacent membrane bodies 7 through the installation groove 13. Brush bristles 16 are fixedly installed on both sides of the fixing plate 15. A groove 17 is opened on the outer surface of the installation plate 14. A sealing ring 18 is provided on the inner wall of the groove 17. Positioning blocks 19 are fixedly installed on the lower surfaces of both ends of the sealing ring 18. Two positioning grooves that are adapted to the corresponding positioning blocks 19 are opened on the inner wall of the groove 17. A fixing bolt 20 is threadedly connected to the outer surface of the installation frame 12. The fixing bolt 20 penetrates the outer surface of the installation frame 12 and is inserted into the installation plate 14.

[0025] By setting up a membrane housing 1, a cap 2, a filter chamber 3, a clear liquid chamber 4, a motor 5, a liquid inlet pipe 6, a membrane body 7, a liquid outlet 8, a liquid inlet pipe 9, a liquid storage box 10, a liquid outlet pipe 11, a mounting frame 12, a mounting groove 13, a mounting plate 14, a fixing plate 15, brush bristles 16, a groove 17, a sealing ring 18, a positioning block 19, and fixing bolts 20, the filter membrane assembly achieves the function of self-cleaning the membrane body 7 during operation. By setting a fixing plate 15 with brush bristles 16 between two adjacent membrane bodies 7, the brush bristles 16 clean the membrane body 7 during the rotation of the membrane body 7, saving time and effort and improving the convenience and practicality of the filter membrane assembly.

[0026] The cover 2 is internally equipped with a disassembly and assembly assembly, which includes two fixing blocks 21. The two fixing blocks 21 are respectively fixedly installed on the outer surfaces of both ends of the membrane shell 1. The inner wall of the cover 2 is fixedly installed with a connecting pipe 22. The inner walls of both ends of the membrane shell 1 are provided with connecting grooves 23 for inserting into the connecting pipe 22. The outer surface of the connecting pipe 22 is fitted with a sealing sleeve 24 that is in contact with the inner wall of the connecting groove 23. The inner wall of the cover 2 is fixedly installed with a limiting block 25. The cover 2 is fitted on the outer surface of the fixing block 21. The outer surface of the fixing block 21 is provided with a limiting groove that matches the limiting block 25. The outer surface of the cover 2 is threaded with an installation bolt 26. The installation bolt 26 penetrates the outer wall of the cover 2 and is inserted into the fixing block 21.

[0027] By setting a fixing block 21, a connecting pipe 22, a connecting groove 23, a sealing sleeve 24, a limiting block 25, and mounting bolts 26, the function of conveniently and quickly disassembling the filter membrane module housing is realized. This import replaces the existing assembly method of the filter membrane module housing, which allows for quick disassembly of the filter membrane module housing, saving time and effort and further improving the practicality of the filter membrane module.

[0028] Working principle: Before using the filter membrane assembly for filtration, the sealing ring 18 is first fitted into the groove 17 on the outer surface of the mounting plate 14, and the two positioning blocks 19 on the sealing ring 18 are respectively inserted into the two positioning slots inside the groove 17 to position the sealing ring 18. Then, the mounting plate 14 is moved to bring the fixing plate 15 closer to the membrane shell 1, so that the fixing plate 15 is aligned with the mounting groove 13 and the mounting plate 14 is aligned with the mounting frame 12. The mounting plate 14 is moved so that the fixing plate 15 is inserted into the interior of the membrane shell 1 through the mounting groove 13. The fixing plate 15 is positioned between two adjacent membrane bodies 7. The mounting plate 14 slides into the interior of the mounting frame 12. After the mounting plate 14 has completely slid into the interior of the mounting frame 12, the fixing bolt 20 is tightened so that the fixing bolt 20 penetrates the outer wall of the mounting frame 12 and inserts into the outer surface of the mounting plate 14 to fix the mounting plate 14 and the fixing plate 15.

[0029] When using the filter membrane assembly for filtration, the raw liquid to be filtered is introduced into the membrane housing 1 through the inlet pipe 9, allowing the raw liquid to enter the storage box 10. At the same time, the motor 5 is started. When the motor 5 runs, it drives the liquid passage pipe 6 to rotate. During the rotation of the liquid passage pipe 6, the membrane body 7 rotates inside the filter chamber 3. The raw liquid inside the storage box 10 is sprayed onto the outer surface of the membrane body 7 through the nozzle. The membrane body 7 filters the raw liquid. The water in the raw liquid enters the interior of the liquid passage pipe 6 through the water permeable holes on the membrane body 7. The filtered water flows along the liquid passage pipe 6, and then leaves the liquid passage pipe 6 through the outlet 8 and enters the interior of the clear liquid chamber 4. It is then discharged from the membrane housing 1 through the outlet pipe 11 connected to the clear liquid chamber 4. The remaining concentrate after the raw liquid is filtered is discharged from the membrane housing 1 through the outlet pipe 11 connected to the filter chamber 3.

[0030] During the operation of the filter membrane assembly, the membrane body 7 rotates while the fixing plate 15 remains fixed, allowing the bristles 16 to brush and clean the surface of the membrane body 7. At the same time, the raw liquid to be filtered washes the outer surface of the membrane body 7, further improving the cleaning effect.

[0031] When it is necessary to disassemble the cover 2, first loosen the mounting bolt 26 so that the mounting bolt 26 extends away from the cover 2. After the mounting bolt 26 separates from the fixing block 21, the cover 2 is released from its fixation. Then pull the cover 2 so that the cover 2 slides on the outer surface of the fixing block 21. The connecting tube 22 drives the sealing sleeve 24 to slide inside the connecting groove 23. When the connecting tube 22 drives the sealing sleeve 24 to slide out from inside the connecting groove 23, the disassembly of the cover 2 is completed.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
