A driving mechanism for driving the pressure filtration mechanism to lift is further arranged at the top of the bracket. The filter screen mechanism passes through and is fixed on an installation table in the middle of the bracket. The filter screen mechanism is composed of a connecting seat, an elastic membrane arranged on the top of the connecting seat and a filter screen fixed at the bottom of the connecting seat. A circle of limit seats is arranged at the top of the connecting seat. A circle of concave rings is arranged at the bottom of the limit seats. A circle of convex rings is arranged at the outer periphery of the elastic membrane. The limit seats are abutted against the installation table. The convex rings are clamped between the concave rings and the installation table to limit the elastic membrane. The filter screen is fixed on a filter screen fixing ring, and the filter screen fixing ring is fixed on the connecting seat below the installation table. A connecting hole is further arranged on the installation table between the installation table and the filter screen fixing ring. A connecting pipe is screwed on the connecting hole, and a valve is arranged on the connecting pipe.

[0006] The pressure filtration mechanism includes a pressure filtration block, and the shape of the bottom of the pressure filtration block corresponds to the shape of the inner circumference of the connecting seat.

[0007] Specifically, the driving mechanism is a lead screw mechanism, and the lead screw of the lead screw mechanism is rotatably connected to the top of the pressure filtration block.

[0008] Further, a guide rod is respectively arranged on both sides of the pressure filtration block, and the upper end of the guide rod passes through a guide hole at the top of the bracket.

[0009] Further, a disc-shaped rubber block is further arranged at the bottom of the pressure filtration block.

[0010] Specifically, the bottom of the rubber block is frustum-shaped.

[0011] Furthermore, the bracket is composed of a base, two columns respectively arranged on both sides of the base, and a top plate arranged on the tops of the two columns. The mounting table is arranged in the middle between the two columns, and mounting holes corresponding to the connecting seat are also provided on the mounting table.

[0016] The beneficial effects of the present utility model are as follows: In the present utility model, the elastic membrane is used to seal the top of the filter screen mechanism. When the pressure filter block descends, it presses the culture medium in the filter screen mechanism through the elastic membrane, avoiding the need to disinfect the inside of the filter screen mechanism and the pressure filter block every time the culture medium is filtered, making it more convenient to use. Moreover, the fixing method of the elastic membrane is stable and reliable, not easily falling off. Corresponding to the above design, the present utility model also makes corresponding designs for the structure of the filter screen mechanism. The entire filter screen mechanism is convenient for disassembly and assembly. A connecting pipe and a valve are also provided on the connecting seat. When filtering the culture medium, the valve is closed, and the pressure filter block descends to filter the culture medium.

The filter screen fixing ring 8 is fixed on the connecting seat 3 below the installation table 2. A connecting hole 9 is further provided on the installation table 2 between the installation table 2 and the filter screen fixing ring 8. A connecting pipe is screwed on the connecting hole 9, and a valve is provided on the connecting pipe;

[0024] The pressure filtering mechanism includes a pressure filtering block 10, and the bottom shape of the pressure filtering block 10 corresponds to the inner peripheral shape of the connecting seat 3.

[0025] In the above structure, the elastic membrane 4 is used to seal the top of the filter screen mechanism. When the pressure filtering block 10 descends, the culture medium in the filter screen mechanism is pressure-filtered through the elastic membrane 4, avoiding the need to disinfect the inside of the filter screen mechanism and the pressure filtering block 10 every time the culture medium is filtered, making it more convenient to use. Moreover, the fixing method of the elastic membrane 4 is stable and reliable, not easy to fall off; corresponding to the above design, the structure of the filter screen mechanism is also correspondingly designed in the above structure. The entire filter screen mechanism is convenient for disassembly and assembly. A connecting pipe and a valve are also provided on the connecting seat 3. When pressure-filtering the culture medium, the valve is closed, and the pressure filtering block 10 descends to pressure-filter the culture medium; when the culture medium in the filter screen mechanism is pressure-filtered, the valve is opened to inject new culture medium to be filtered, and continuous pressure filtering can be carried out, which is beneficial to improving the filtering efficiency of the culture medium.

[0028] In another embodiment, asFigure 2 As shown, a disc-shaped rubber block 12 is further provided at the bottom of the filter pressing block 10 to prevent the rigid extrusion from causing the filter screen 5 to rupture.

[0029] In another embodiment, as Figure 2 shown, the bottom of the rubber block 12 is frustum-shaped.

[0030] In another embodiment, as Figure 1 shown, the bracket is composed of a base 13, two columns 14 respectively arranged on both sides of the base 13, and a top plate 15 arranged on the tops of the two columns 14. The mounting table 2 is arranged in the middle between the two columns 14, and mounting holes corresponding to the connecting seat 3 are further provided on the mounting table 2.
