[0002] Reverse osmosis membrane is a highly efficient separation device widely used in the field of water treatment, and is often used in processes such as seawater desalination, sewage treatment and drinking water purification. Reverse osmosis membrane has the characteristics of highly selective separation, which can effectively remove salt, impurities and microorganisms in water, thereby improving water quality. However, reverse osmosis membranes are easily contaminated during long-term use, especially dirt, microorganisms and other pollutants will accumulate on the membrane surface and pores, which not only reduces the separation efficiency of the membrane, but also shortens its service life. In order to solve this problem, chemical cleaning, mechanical cleaning or gas cleaning are usually used to regularly maintain the reverse osmosis membrane to ensure that it maintains efficient operation.

[0037] In this embodiment, a first connecting plate 3 is connected to one side of the box body 6 by design, and a connecting groove 4 is opened on the outer wall of one side of the first connecting plate 3, wherein a box cover 2 is provided on one side of the first connecting plate 3, and a corresponding connection is made through the connecting groove 4, and a handle 1 is connected to one side of the box cover 2, and the box cover 2 can be removed by the handle 1, so that the reverse osmosis membrane body 21 in the first connecting plate 3 can be taken out, and the reverse osmosis membrane body 21 that needs to be cleaned can be cleaned, so it is convenient to disassemble and replace the reverse osmosis membrane body 21, making the device more practical;

[0038] The inner wall of the box body 6 is respectively provided with three partitions, namely, a first inner cavity 16, a second inner cavity 17 and a third inner cavity 18, wherein the lower end of the first inner cavity 16 is correspondingly connected to the input pipe 13 connected to the outer wall of the box body 6, and the detergent can be transported into the box body 6 through the input pipe 13. At this time, the detergent will enter the reverse osmosis membrane body 21 through the first connecting cover 20. At this time, the dirt on the reverse osmosis membrane body 21 can be dissolved and infiltrated into the second inner cavity 17, and can be discharged through the first output pipe 14. Some dirt cannot be dissolved by the solvent and will remain inside the reverse osmosis membrane body 21. At this time, air cleaning is required, and the hydraulic pump 11 is started. The hydraulic pump 11 drives the movable rod 23 and the suction pipe 25 to rotate and displace on the inner wall of the reverse osmosis membrane body 21, and the residue on the inner wall of the reverse osmosis membrane body 21 is absorbed into the movable rod 23 through the suction pipe 25 and discharged through the exhaust hole 24. At this time, the gas and dirt can be discharged from the box body 6 through the second output pipe 15. The above operation can be repeatedly performed to clean the reverse osmosis membrane body 21.

[0039] Working principle:

[0040] like Figure 1-6As shown, hold the handle 1 and remove the box cover 2 from the first connecting plate 3. Next, put the first connecting cover 20, the reverse osmosis membrane body 21 and the second connecting cover 22 into the box body 6. At this time, the second connecting cover 22 is connected to the second fixing ring 8, and the first connecting cover 20 is connected to the first fixing ring 7. Then, the box cover 2 and the first connecting plate 3 are sealed and connected using the first bolt 5. Next, the detergent is transported into the box body 6 through the input pipe 13, and the detergent enters the reverse osmosis membrane body 21 through the first connecting cover 20. The detergent can dissolve and penetrate the dirt on the reverse osmosis membrane body 21, and the dirt will enter the second inner cavity 17 and finally be discharged through the first output pipe 14. However, some dirt cannot be dissolved and will remain inside the reverse osmosis membrane body 21. In order to clean these residues, start the hydraulic pump 11, and the hydraulic pump 11 will drive the movable rod 23 and the suction pipe 25 to rotate and displace on the inner wall of the reverse osmosis membrane body 21. In this way, the residue on the inner wall of the reverse osmosis membrane body 21 will be absorbed into the movable rod 23 and discharged through the exhaust hole 24. Subsequently, the gas and dirt in the box body 6 are discharged through the second output pipe 15. Repeat the above operation to clean the reverse osmosis membrane body 21 and take it out to obtain a clean reverse osmosis membrane body 21. Finally, repeat the same steps to clean other reverse osmosis membrane bodies 21 that need to be cleaned to complete the entire cleaning process.
