Description

Technical Field

[0001] The utility model relates to the technical field of nanofiltration membrane cleaning, in particular to a nanofiltration membrane high-efficiency cleaning device. Background Art

[0002] Nanofiltration membrane is a functional semipermeable membrane that allows solvent molecules or certain low molecular weight solutes or low-valent ions to pass through. It is a special and promising separation membrane variety, named because it can retain substances of about nanometer size. It is used to remove organic matter and color from surface water, remove hardness from groundwater, partially remove soluble salts, concentrate fruit juice, and separate useful substances in medicines.

[0003] The Chinese utility model patent with patent application number 202222276961.8 provides a high-efficiency cleaning device for filter membranes. By providing a guide roller bracket and a stepper motor, the rolled ultrafiltration membrane can be automatically wound, and the surface of the rolled ultrafiltration membrane can be frictionally cleaned by using bearings, rotating shafts, cleaning cotton and V-shaped wipers, thereby facilitating the cleaning of the surface of the rolled ultrafiltration membrane. Since the rotating shaft is W-shaped, the surface dirt can be removed while pulling the rolled ultrafiltration membrane. The rectangular shell and water filter cotton plate can be used to wipe the surface of the rolled ultrafiltration membrane with clean water to prevent the situation where there are too many water stains and it is inconvenient to dry it. Finally, the fan and heating wire can be used to dry the rolled ultrafiltration membrane, which facilitates drying and avoids the problem of not being able to clean the rolled ultrafiltration membrane and not being able to dry the rolled ultrafiltration membrane, resulting in reduced cleaning effect.

[0004] However, during the use of the above-mentioned equipment, it was found that when the nanofiltration membrane was removed from the decontamination tank, the nanofiltration membrane would bring out a portion of the clean water in the decontamination tank, causing some of the clean water to fall onto the base, which could easily cause a waste of water resources and easily wet the surrounding environment, increasing the difficulty and inconvenience of subsequent cleaning work. Utility Model Content

[0023] The cleaning assembly 6 includes a pump 61, which is mounted on a liquid storage tank 62. The pump 61 is connected to a liquid inlet pipe 63, which passes through the pump 61 and is connected to a shunt pipe 64. A spray pipe 65 is mounted on the shunt pipe 64, and the spray pipe 65 is arranged in the cleaning chamber 22.

[0024] A rotating roller 1 3 is disposed at one end of the top of the base 1, and a rotating roller 2 4 is disposed at the other end of the top of the base 1, and one end of the rotating roller 1 3 and the rotating roller 2 4 are both connected to a motor 5;

[0025] A top cover 21 is installed on the top of the cleaning box 2, an inclined surface 1 222 is provided at the bottom of the cleaning chamber 22, and the lower end of the inclined surface 1 222 is connected to the circulation groove 221, and an inclined surface 231 is provided at the bottom of the drying chamber 23, and the lower end of the inclined surface 231 is connected to the circulation groove 221 through a connecting port 232, and the connecting port 232 is provided on the partition 24;

[0026] A rotating rod 223 is provided in the cleaning chamber 22. The rotating rod 223 is arranged parallel to the spray pipe 65. The rotating rod 223 is rotatably connected to the inner wall of the cleaning chamber 22.

[0027] A rotating shaft 233 is rotatably connected in the drying chamber 23 . The rotating shaft 233 is arranged on a side close to the partition 24 . Water-absorbing cotton 234 is arranged on the rotating shaft 233 . A ventilation hole 7 is installed on the inner wall of the drying chamber 23 .

[0028] In this scheme, the nanofiltration membrane is wound on the rotating roller 3, and the rotating roller 3 is controlled by the motor 5 to rotate so as to release the nanofiltration membrane. The nanofiltration membrane enters the cleaning chamber 22 from one side of the cleaning box 2. The nanofiltration membrane first passes through the top of the rotating rod 223 that is rotatably arranged on one side of the cleaning chamber 22, then passes through the bottom of the rotating rod 223 that is rotatably arranged in the middle of the cleaning chamber 22, and finally passes through the top of the rotating rod 223 that is rotatably arranged on the other side of the cleaning chamber 22 and enters the drying chamber 23. The nanofiltration membrane that enters the drying chamber 23 first passes through the middle of the rotating shaft 233, and finally moves out from the other side of the cleaning box 2 and is wound on the rotating roller 24 for membrane collection. In the process of the nanofiltration membrane passing through the cleaning box 2, the nanofiltration membrane is cleaned by the cleaning component 6;

[0029] The cleaning liquid in the liquid storage tank 62 is extracted by the pump 61 in the cleaning assembly 6, so that the cleaning liquid enters the shunt pipe 64 through the liquid inlet pipe 63, and the cleaning liquid is sprayed on the nanofiltration membrane passing through the cleaning tank 2 by using multiple spray pipes 65 connected to the shunt pipe 64. The spray pipes 65 are respectively arranged at the bottom of both sides of the cleaning chamber 22 and the top in the middle of the cleaning chamber 22, so that the front and back of the nanofiltration membrane can be cleaned at the same time. The cleaning liquid after cleaning flows onto the inclined surface 1 222, and enters the liquid storage tank 62 along the inclined surface 1 222 through the flow slot 221;

[0030] The nanofiltration membrane entering the drying chamber 23 first passes through the rotating shaft 233, and the absorbent cotton 234 on the rotating shaft 233 is attached to the front and back of the nanofiltration membrane, so as to absorb the water attached to the front and back of the nanofiltration membrane, reduce the residual water on the nanofiltration membrane, and at the same time, push a part of the water that is not absorbed in time to fall on the inclined surface 231, and the water falling on the inclined surface 231 enters the flow groove 221 along the inclined surface 231 through the connecting port 232, and the partition 24 between the cleaning chamber 22 and the drying chamber 23 can prevent too much cleaning liquid from entering the drying chamber 23, and the inclined surface 1 222 and the inclined surface 231 can be used to guide the excess cleaning liquid after cleaning to the flow groove 221 and enter the liquid storage tank 62, so as to realize the reuse of the cleaning liquid and avoid the waste of the cleaning liquid;

[0031] A fan is arranged inside the ventilation hole 7 arranged inside the drying chamber 23. The ventilation hole 7 is arranged above and below the nanofiltration membrane. The rotation of the fan can accelerate the air flow above and below the nanofiltration membrane, so that the remaining water stains on the nanofiltration membrane after passing through the absorbent cotton 234 evaporate quickly, further completing the drying of the nanofiltration membrane and avoiding the situation where the cleaning liquid is taken out of the cleaning box 2. The dried nanofiltration membrane is moved out from the other side of the cleaning box 2, and the motor 5 is used to control the rotation of the rotating roller 24 to collect and wind the dried nanofiltration membrane.
