When the equipment is running, the filter cartridges 22 in different filter chambers 12 can be taken out and placed, so that the filter screen 24 can be replaced or cleaned, thereby further improving the filtering effect of the microbial agent.

[0027] A filter mechanism 2 is provided in the filter chamber 12, and the filter mechanism 2 includes a positioning platform 21 and a filter cartridge 22. The positioning platform 21 is fixedly connected to the bottom of the filter chamber 12, and a liquid inlet pipe 6 extending to the outside of the filter chamber 12 is provided on the positioning platform 21. The filter cartridge 22 is inserted above the positioning platform 21, and a connecting pipe 23 is provided at the bottom of the filter cartridge 22.

A plurality of liquid outlet troughs 26 are provided on the side wall of the pull-out rack 25 at intervals.

[0028] After the microbial agent enters the filter cartridge 22 through the liquid inlet pipe 6, the pressure of the microbial agent causes the microbial agent to flow over the filter screen 24. The microbial agent filtered by the filter screen 24 enters the filter chamber 12 from the liquid outlet trough 26. The microbial agent entering the filter chamber 12 enters the storage chamber 11 through the connecting chamber 13.

[0029] The tops of the storage chamber 11 and the filter chamber 12 are both provided with a taking and placing groove, the outside of which is fixedly connected with a connecting cylinder 14, the inside of which is detachably connected with an extrusion cylinder 15, the top of which is fixedly connected with a sealing cover 16, the inner wall of the connecting cylinder 14 is provided with an internal thread, the outer wall of the extrusion cylinder 15 is provided with an external thread that matches the internal thread, through the provided sealing cover 16 and the extrusion cylinder 15, it is possible to cooperate with the pulling rack 25 to fix the filter cylinder 22 on the positioning platform 21, and the storage chamber 11 and the filter chamber 12 can be opened and closed.

[0030] In some embodiments, the positioning platform 21 includes a circular disc and a conical disc. The circular disc is fixedly connected in the filter chamber 12, and the conical disc is fixedly connected above the circular disc. The conical disc is adapted to the positioning groove set at the bottom of the filter cartridge 22. Through the set conical disc and positioning groove, the filter cartridge 22 can be limited and installed inside the filter chamber 12.

[0031] Example 2

[0032] like Figure 5 As shown, in order to facilitate the disassembly and assembly of the filter 24, a locking assembly 4 is provided on the filter cartridge 22 for fixing the filter 24. In some embodiments, a plurality of locking assemblies 4 are provided, and the plurality of locking assemblies 4 are circumferentially distributed on the outside of the filter cartridge 22. Each locking assembly 4 includes a positioning cylinder 41 and a positioning bolt 42. The positioning cylinder 41 is fixedly connected to the outer wall of the filter cartridge 22. The positioning bolt 42 passes through the positioning cylinder 41 and is threadedly connected to the threaded hole provided on the filter 24. Through the provided positioning cylinder 41 and the positioning bolt 42, the filter 24 placed on the limit frame 3 can be disassembled and assembled, thereby facilitating the disassembly and assembly of the filter 24 in the filter cartridge 22, so that the filter 24 can filter the microbial agent or clean the filter 24.

[0033] Example 3

[0034] In order to discharge the microbial agent in the storage chamber 11 out of the filter tank 1, a liquid pumping mechanism 5 is also included. The liquid pumping mechanism 5 includes a liquid pump. The liquid pump is fixedly connected to the filter tank 1. The liquid inlet end of the liquid pump is connected to a liquid pumping pipe 51. The liquid pumping pipe 51 passes through the sealing cover 16 on the storage chamber 11 and extends to the inside of the storage chamber 11. The liquid outlet end of the liquid pump is connected to the discharge pipe of the cylinder 14. The microbial agent in the storage chamber 11 can be pumped out of the filter tank 1 through the provided liquid pump.

[0035] The working principle of the present invention is as follows: the external liquid supply device is started, the microbial agent is allowed to enter each filter cavity 12 through the liquid inlet pipe 6, and the microbial agent is allowed to enter the interior of the connecting pipe 23 on the filter cartridge 22 at the same time. As the microbial agent is continuously injected, the liquid level of the microbial agent in the filter cartridge 22 continues to rise until it overflows the filter screen 24 and filters the microbial agent.

[0036] As the liquid level rises, the filtered microbial agent can be discharged into the filter chamber 12 through the liquid outlet 26, and all the microbial agents in the filter chamber 12 will enter the storage chamber 11 through the connecting chamber 13;

[0037] Start the liquid extraction pump, so that the liquid extraction pipe 51 can extract the microbial agent in the storage chamber 11 out of the storage chamber 11, and then discharge the microbial agent through the liquid discharge pipe;

[0038] When the filter screen 24 in one of the filter chambers 12 needs to be replaced, the sealing cover 16 on the corresponding filter chamber 12 needs to be rotated until the extrusion cylinder 15 is separated from the inside of the connecting cylinder 14. At this time, it is only necessary to pull the pull-out frame 25 to remove the filter cylinder 22 from the filter chamber 12, and then rotate the positioning bolt 42 to disengage the filter screen 24 from the positioning bolt 42, thereby removing the filter screen 24 from the filter cylinder 22, cleaning or replacing the filter screen 24, and while cleaning or replacing the filter screen 24, the microbial agent continues to be filtered in the remaining filter chambers 12.
