Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a cleaning device for an ultrafiltration membrane. Background Art

[0002] Ultrafiltration membrane is a microporous filtration membrane that can screen out solute molecules smaller than the pore size under a certain pressure. This technology involves using pressure difference as a driving force to separate small and medium molecules in the solute through a semipermeable membrane. Ultrafiltration membranes are needed inside water purifiers in daily life. Water purifiers generally consist of: a shell, a screw cap, and an ultrafiltration membrane connected to the screw cap. After long-term use, the screw cap needs to be opened and the ultrafiltration membrane needs to be taken out and cleaned with a cleaning device. The ultrafiltration membrane is made of: cellulose acetate, cellulose acetate ester, polyethylene, polysulfone, and polyamide. Generally, various types of membrane components such as tubular, plate, roll, and capillary are pre-made.

[0003] Most of the cleaning devices currently used, when cleaning the ultrafiltration membrane, simply place the ultrafiltration membrane in the acid wash solution and wait for the stains on the ultrafiltration membrane to automatically decompose. This method has a slow cleaning effect and cannot improve the cleaning speed. At the same time, after cleaning the stains, the staff needs to manually remove the ultrafiltration membrane from the acid wash solution and place the ultrafiltration membrane in another device containing clean water for secondary cleaning. This method increases the workload of the staff. Utility Model Content
