With the continuous progress of technology, the performance of the precision filter is continuously improved, which will provide more efficient and reliable filtering solutions for various industries. Therefore, we propose a pipeline precision filter.

[0003] The prior art has the following defects in use:

[0004] The pipeline precision filter in the prior art can only adjust the filtering effect by replacing the material of the filter core and using filter cores with different pore sizes when filtering the fluid inside the pipeline. This not only takes a lot of time and effort to install and disassemble, but also causes the pipeline to be interrupted during the filter adjustment process, reducing the flow efficiency of the fluid in the pipeline.

[0005] The pipeline precision filter in the prior art has relatively single functionality and can only perform simple filtering and separation of impurities inside the fluid. After the filter core of the filter is used for a period of time, the internal pores are blocked or shielded by impurities, which gradually increases the flow resistance of the fluid and reduces the working efficiency of the filter.
