The cleaned nanofiber membrane needs to be taken out or the winding roller needs to be replaced before the cleaning operation can be performed again, resulting in a decrease in the cleaning efficiency of the equipment. Therefore, a nanofiber membrane cleaning device is proposed. Utility Model Content

[0026] Working principle: Nanofiber membrane is a thin film composed of nano-scale fibers. It has a wide range of applications in filtration, adsorption, isolation, protection and sensing. It has a high specific surface area, high porosity and small fiber diameter. Therefore, nanofiber membrane is often used in environmental protection, health care and biotechnology. In order to ensure the normal use of nanofiber membrane, it needs to be cleaned and maintained regularly. During the cleaning process of the existing cleaning device, the winding roller will be full and the cleaning operation will not be carried out. The cleaned nanofiber membrane needs to be taken out or the winding roller needs to be replaced before it can be cleaned again. Operation leads to reduced cleaning efficiency of the equipment. In order to solve this problem, a collection mechanism and a cleaning mechanism are set up, and the membrane body 101 to be cleaned is inserted into the inner side of the shell 1, and one end of the membrane body 101 is fixed on the collection roller 4.

Then, the water pump 18 introduces clean water into the inside of the water spray pipe 19 to flush out the impurities on its surface. Finally, it passes through the squeezing roller 21 to minimize the residual liquid on its surface. The membrane body 101 moves to the drying area inside the shell 1 with the cooperation of the limiting roller 22. When passing through the water absorption roller 24, the residual liquid on the surface of the membrane body 101 is absorbed. Then, it passes through the electric heating rod 25 to heat and dry it to completely remove the moisture on its surface. Finally, it is collected by the collecting roller 4. If one side When the collecting roller 4 is full, the limit plate 10 is pulled to pull out the insertion rod 9, and the rotating frame 3 is rotated to move the collecting roller 4 on the other side to the collecting position. At this time, the limit plate 10 is released, and the spring 11 pulls the insertion rod 9 to re-insert into the inner side of the positioning hole 8 to fix the position of the rotating frame 3. At this time, the large gear 5 at one end of the collecting roller 4 is engaged with the small gear 7, and the servo motor 6 can be controlled to drive the collecting roller 4 to rotate with the cooperation of the gears, thereby collecting the cleaned membrane body 101, ensuring that the cleaning efficiency of the device will not decrease, and solving the problem that replacing the winding roller will affect the cleaning efficiency of the device.
