Conductive paste has a wide range of applications in the electronics industry, mainly used for wiring of thick film integrated circuits, electrodes of ceramic capacitors, leads of hybrid integrated circuits, etc. During the production process of conductive paste, there are relatively large particles and impurities inside, which affect the quality of conductive paste. Therefore, a pressure filtration device for conductive paste is needed to filter it.

Finally, the conductive paste is collected through the discharge port at the bottom. However, the height of the discharged material in this way is fixed and not suitable for different collection devices. After retrieval, it is found that the technical solution provided by the utility model with the application number CN202123142384.5 also has the above problems. Summary of the Utility Model

After cleaning the filter net 6, insert the filter net 6 into the inside of the filter barrel 1. Pull the bolt 19, and the bolt 19 drives the limiting plate 20 to slide.
