[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1-4 , the utility model provides a technical solution:

[0024] A reverse osmosis membrane cleaning and drying device comprises a vertical pipe 1, wherein two sides of the top of the vertical pipe 1 are respectively provided with a horizontal pipe 1 2 and a horizontal pipe 2 3 connected thereto, wherein the horizontal pipe 1 2 is respectively provided with a water pump 4 and a switch valve 1 5, wherein the end of the horizontal pipe 2 3 is fixedly provided with a heating box 6 connected thereto, wherein a plurality of groups of heating pipes 7 are arranged in the heating box 6, wherein the horizontal pipe 2 3 is respectively provided with a fan 8 and a switch valve 2 9, and a spray plate 10 is provided at the bottom end of the vertical pipe 1, wherein the spray plate 10 is provided with spray holes 11 evenly distributed.

[0025] When the reverse osmosis membrane cleaning and drying device is working, the cleaning liquid is first pumped into the horizontal pipe 2 through the water pump 4, and then the switch valve 5 is opened, and the cleaning liquid flows into the spray disc 10 through the vertical pipe 1, and is sprayed onto the surface of the reverse osmosis membrane through the spray holes 11 evenly distributed on the spray disc 10 for deep cleaning. After cleaning, the water pump 4 is turned off and the valve 1 is closed to stop the supply of cleaning liquid. Subsequently, the heating tube 7 in the heating box 6 is started to heat the air, and the fan 8 and the switch valve 2 9 are turned on at the same time. The hot air enters the vertical pipe 1 through the horizontal pipe 2 3 and is then sprayed out by the spray disc 10 to quickly dry the reverse osmosis membrane and effectively remove residual moisture. The reverse osmosis membrane cleaning and drying device has the function of switching between cleaning liquid and drying air spraying, which not only significantly improves the efficiency of cleaning and drying, but also can quickly remove residual moisture on the reverse osmosis membrane during the drying stage, effectively avoiding the risk of secondary pollution.

[0026] A rotary joint 12 is rotatably provided at the bottom end of the vertical pipe 1, and the spray disc 10 is connected to the rotary joint 12. A rotating member 13 is provided on the vertical pipe 1 and the rotary joint 12. The rotating member 13 includes a horizontal plate 131 fixedly installed on the side of the vertical pipe 1, a motor 132 fixedly installed on the horizontal plate 131, a gear 133 rotatably provided on the horizontal plate 131, and a gear 2 114 fixedly installed on the rotary joint 12. The output shaft end of the motor 132 is fixedly installed with the rotating shaft end of the gear 133, and the gear 1 133 is meshed and transmission-connected with the gear 2 114;

[0027] The motor 132 drives the rotation of the first gear 133. Through the meshing transmission between the first gear 133 and the second gear 114, the rotating joint 12 and the spray disc 10 connected thereto are driven to rotate synchronously. During the rotation of the spray disc 10, the spray holes 11 thereon can evenly spray the cleaning liquid or drying air on the surface of the reverse osmosis membrane, ensuring cleaning without dead corners and comprehensive drying. This dynamic cleaning and drying method not only improves the cleaning efficiency but also enhances the cleaning and drying effects, making the surface of the reverse osmosis membrane cleaner and drier.

[0028] A filtering part 14 is arranged on the vertical pipe 1. A filter plate 15 is arranged inside the filtering part 14. A plug plate 16 is slidably arranged on one side of the filtering part 14. The plug plate 16 is fixedly installed on one side of the filter plate 15. A handle 17 is fixedly installed on the outer side of the plug plate 16.

[0029] When the cleaning liquid or drying air passes through the vertical pipe 1, they will first pass through the filter plate 15 in the filtering part 14 for filtration. The filter plate 15 can effectively block and remove impurities such as solid particles and suspended matters therein, ensuring that only pure cleaning liquid or hot air reaches the spray disc 10, further reducing the pollution during the cleaning or drying process of the reverse osmosis membrane. In addition, the plug plate 16 is fixedly installed with the filter plate 15. By sliding the plug plate 16, the filter plate 15 can be conveniently taken out for cleaning or replacement to maintain the filtering effect.

[0030] Sealing rubber plates are laid on the sides of the plug plate 16.

[0031] The sealing rubber plates on the outer side of the plug plate 16 ensure the sealing performance of the filtering part 14 and prevent liquid or gas leakage.

[0032] Working principle:

[0033] When the reverse osmosis membrane cleaning and drying device works, first, the cleaning liquid is pumped into the first horizontal pipe 2 by the water pump 4. Then, the switch valve 5 is opened, and the cleaning liquid flows into the spray disc 10 through the vertical pipe 1 and is sprayed onto the surface of the reverse osmosis membrane through the evenly distributed spray holes 11 on the spray disc 10 for in-depth cleaning. After the cleaning is completed, the water pump 4 and the first switch valve are closed to stop the supply of the cleaning liquid. Subsequently, the heating tube 7 in the heating box 6 is started to heat the air. At the same time, the fan 8 and the second switch valve 9 are opened, and the hot air enters the vertical pipe 1 through the second horizontal pipe 3 and is then sprayed out by the spray disc 10 to quickly dry the reverse osmosis membrane and effectively remove the residual moisture.

[0034] During the cleaning or drying process of the reverse osmosis membrane, the motor 132 drives the first gear 133 to rotate. Through the meshing transmission between the first gear 133 and the second gear 114, the rotating joint 12 and the spray disc 10 connected thereto are driven to rotate synchronously. During the rotation of the spray disc 10, the spray holes 11 thereon can evenly spray the cleaning liquid or drying air on the surface of the reverse osmosis membrane, ensuring cleaning without dead angles and comprehensive drying. This dynamic cleaning and drying method not only improves the cleaning efficiency but also enhances the cleaning and drying effects, making the surface of the reverse osmosis membrane cleaner and drier;

[0035] When the cleaning liquid or drying air passes through the vertical pipe 1, they will first pass through the filter plate 15 in the filtering part 14 for filtering. The filter plate 15 can effectively block and remove impurities such as solid particles and suspended matters therein, ensuring that only pure cleaning liquid or hot air reaches the spray disc 10, further reducing the pollution during the cleaning or drying process of the reverse osmosis membrane. In addition, the plug plate 16 is fixedly installed with the filter plate 15, and the filter plate 15 can be conveniently taken out for cleaning or replacement by sliding the plug plate 16 to maintain the filtering effect. The sealing rubber plate outside the plug plate 16 ensures the sealing of the filtering part 14 and prevents liquid or gas leakage;

[0036] The reverse osmosis membrane cleaning and drying device has the function of switching between spraying the cleaning liquid and the drying air, which not only significantly improves the cleaning and drying efficiency but also can quickly remove the residual moisture on the reverse osmosis membrane during the drying stage, effectively avoiding the risk of secondary pollution.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes, should be covered within the protection scope of the present invention.
