[0002] In various industrial production processes, there is often a need to separate, concentrate, classify, and purify a certain aqueous solution. The traditional methods used are processes such as precipitation, filtration, heating, freezing, distillation, extraction, and crystallization. These methods exhibit disadvantages such as long process flow, high energy consumption, large material losses, large equipment, low efficiency, and cumbersome operation. Replacing a certain traditional technology with ultrafiltration membrane technology can obtain significant economic benefits.

However, the surface of the filter element is a smooth cylindrical structure, resulting in increased difficulty in fixing and assembling the filter element during use. Moreover, the liquid injection pipe fitting inside the filter element is an integral structure. During the long-term liquid injection process, a part of the dirt will remain inside the pipe fitting, which will affect the liquid injection efficiency of the pipe fitting. Summary of the Invention
