The filter press storage tube 13 is made of a transparent material, which facilitates personnel to directly observe the state inside the filter press storage tube 13.

[0027] Specifically, when the present utility model is in use, the cosmetic solution to be filter-pressed is injected into the filter press storage tube 13 through the feed port 16. After the injection is completed, the valve switch 17 on the feed port 16 is closed. Then, an external gas pressurization device is used to supply gas to the pressurization interface 15, and the gas is injected into the filter press storage tube 13 through the pressurization interface 15, so that the internal pressure of the filter press storage tube 13 increases and can squeeze the cosmetic solution downward. At the same time, the crank 9 can be manually held and rotated to drive the stirring rod 6, and the stirring rod 6 drives the stirring blades 7 to rotate, so as to stir the cosmetic solution inside the filter press storage tube 13, preventing stratification and precipitation in the solution, which may cause blockage of the filter screen plate 21 and affect the filter press. And when the internal pressure of the filter press storage tube 13 is too high and reaches the maximum bearing range of the pressure relief valve 10, the pressure relief valve 10 automatically discharges the pressure outward, effectively ensuring the safety of the equipment and personnel.
