Different applications may require the use of microfiltration membranes of different precision and materials. Replaceable microfiltration membrane assembly makes it easy to replace the microfiltration membrane when needed to meet different filtration requirements, thereby increasing the flexibility of the system.

[0003] After searching, the Chinese patent document announcement number: CN220425018U discloses a microfiltration membrane assembly with strong anti-fouling ability, which belongs to the technical field of microfiltration membrane assembly.

After the cover body 7 and the shell 1 are closed, the sealing ring 11 is inserted into the annular sealing groove 12, and under the action of the shell 1, the movement of the sealing ring 11 is realized, so that the sealing ring 11 drives the rotation of the rotating rod 10, thereby realizing that the rotating rod 10 drives the sliding rod 1 5 slides, and the sliding rod 15 drives the compression of the telescopic spring 9, thereby realizing the sealing of the shell 1, thereby preventing the occurrence of leakage accidents and reducing the production cost. After the water flows into the connecting pipe 2, it hits the buffer head 18, and the buffer head 18 drives the sliding of the long strip 17, so that the long strip 17 drives the movement of the connecting rod 19, thereby realizing that the connecting rod 19 drives the compression of the reset spring 23, and the water flows into the hollow ring 20, thereby realizing the buffering of the water flow, thereby reducing the deformation, damage or microcracks of the membrane, and improving the stability and service life of the membrane.
