[0002] Plant fermentation broth is a product of plant fermentation. It is often used in people's daily lives. After fermentation is completed, the fermentation broth usually needs to be purified, and filtration is an important step in the purification process.

[0003] According to the authorization announcement number CN112704947A, a filtration and purification device for plant fermentation broth is disclosed, including a fixed base. The top outer wall of the fixed base is provided with a collection trough. Both sides of the top outer wall of the fixed base are bolted to fixed rods, and the outer walls of the two fixed rods on opposite sides are bolted to a box body. The top outer wall of the box body has a liquid inlet, and the inner wall of the liquid inlet is provided with a liquid inlet hopper. The bottom outer wall of the box body has a liquid outlet, and the inner wall of the liquid outlet is bolted to a liquid outlet plate.

[0004] In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the prior art: The aforementioned example uses an inclined filter screen to improve the flowability of the fermentation broth. The filter screen has a horn-shaped cross-section, and the top of the screen is wavy, which enhances the turbulence of the fermentation broth as it flows over it. However, during use, impurities in the fermentation broth easily clog the filter screen's pores, affecting filtration efficiency, and it is inconvenient to clean the impurities from the filter screen surface.

[0005] Therefore, we propose a filtration and purification device for plant fermentation broth, which can solve the above problems. Utility Model Content

[0012] As an optional solution to the technical solution of this application, a bracket is fixedly connected to the top of the purification shell, and the electro-hydraulic push rod is fixedly connected to the middle of the upper surface of the bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: controlling the electro-hydraulic push rod can push the pressure plate to move downward and insert it into the filter cylinder, squeezing the fermentation liquid on the surface of the carrier plate.
