[0043] A third-stage microbial filter 83 and a stop valve 84 are installed in the third pipeline 73;

[0044] The third pipeline 73 is formed with a fourth pipeline 74 which is communicatively connected to the secondary microorganism filter.

[0045] As an embodiment of the present invention, the third-stage microorganism filter 83 is a filter mesh.

[0046] As an embodiment of the present invention, the secondary microorganism filter unit includes a plurality of second filter holes 52 uniformly formed on the microorganism outlet pipe 5 and a cover 6 sealedly formed on the outer side of the second filter holes 52;

[0047] The fourth pipe 74 is communicatively connected to the housing 6 .

[0048] As an embodiment of the present invention, a sensor component 82 for detecting the presence or absence of microorganisms is installed in the first pipeline 71 .

[0049] As an embodiment of the present invention, the second filter hole 52 and the third-stage microorganism filter 83 can completely filter the microorganisms.

[0050] As an embodiment of the present invention, a limited flow hole 51 is formed at the bottom of the microorganism outlet pipe 5 .

[0051] As an embodiment of the present invention, a hollow flow channel 50 is formed in the microorganism outlet pipeline 5 , and a culture liquid chamber 60 is formed between the microorganism outlet pipeline 5 and the cover shell 6 .

[0052] As an embodiment of the present invention, the filtering device for collecting microorganisms further comprises a mounting top plate 10;

[0053] The rotary driver 20 is mounted on the mounting top plate 10 through the mounting frame 11;

[0054] The hollow tube 21 is rotatably mounted on the mounting top plate 10 .

[0055] As an embodiment of the present invention, the filtering device for collecting microorganisms further includes a supporting bottom plate 12 , and the mounting top plate 10 is fixedly connected to the top of the supporting bottom plate 12 .

[0056] The working principle of the microbial collection filtration device is as follows:

[0057] The feed pump 30 pumps the culture solution containing microorganisms in the vessel into the hollow tube 21. Under the action of gravity and rotational force, the culture solution containing microorganisms is evenly sprinkled from the branch pipe 22 onto the upper part of the primary microorganism filter 4.

[0058] Since the middle portion of the primary microbial filtration portion 4 is concave, the culture fluid containing microorganisms has a tendency to roll toward the microbial discharge hole; during the process, most of the culture fluid containing a small amount of small-sized microorganisms is filtered out from the first filter hole into the accommodating cavity 41, and most of the microorganisms mixed with a small amount of culture fluid are introduced from the microbial discharge hole into the hollow flow channel 50.

[0059] Under the action of the flow-limiting hole 51, a small amount of culture fluid in the hollow flow channel 50 is filtered out from the second filter hole 52 into the culture fluid chamber 60, and is successively guided to the outside of the device through the fourth pipeline 74 and the third pipeline 73; and the microorganisms that are basically completely separated from the culture fluid are guided to the outside of the device through the flow-limiting hole 51;

[0060] The microorganism outlet pipe 5 may also be configured to be folded, and the culture fluid may be substantially completely separated by arranging the second filter hole 52 at the folded portion.

[0061] Most of the culture fluid contains a small amount of small-sized microorganisms and is guided through the first pipeline 71. When the sensor component 82 does not sense the microorganisms, the secondary filtration pump 81 does not operate and the stop valve 84 is in an open state, and the culture fluid is guided through the first pipeline 71 to the third pipeline 73, and then guided to the outside of the device through the third pipeline 73;

[0062] When the sensor assembly 82 senses the microorganisms, the secondary filtration pump 81 starts to operate and the stop valve 84 is closed. Most of the culture fluid containing a small amount of small-sized microorganisms is redirected to the top of the primary microorganism filtration part 4 for filtration under the action of the secondary filtration pump 81, so that the small amount of small-sized microorganisms can slide into the hollow flow channel 50.

[0063] The three-stage microorganism filter 83 provided therein can ensure that a small amount of small-sized microorganisms are not wasted and discharged.

[0064] We try to make the first filter hole as large as possible to improve the efficiency of filtering out the culture solution; since the sizes of the cultured microorganisms are different, the size of the first filter hole satisfies that most of the microorganisms are not filtered out at all, that is, its size is slightly smaller than that of small-sized microorganisms, but microorganisms have less deformability, so a small number of small-sized microorganisms can be guided into the accommodating chamber 41 under the action of gravity and rotational force;

[0065] Since the size of the first filter pores is smaller than the size of the microorganisms, a small amount of small-sized microorganisms pumped in multiple times can eventually slide completely into the microorganism outlet pipeline 5 .

[0066] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
