It is suitable for the production of a variety of products and reduces energy consumption. Liquid strains are liquid culture mediums, and are produced in a biological fermentation tank by deep culture technology. In liquid form, edible fungi strains; however, when the existing fermentation tank is used, the liquid strains contain iron impurities and other particles, and these iron impurities and other particles will affect the later cultivation of the liquid strains, so it is necessary to filter the iron impurities and other particles of the liquid strains. Therefore, when the staff pours the liquid strains into the fermentation tank, a funnel is also needed to assist. When the funnel is used to filter the liquid strains, the filtering effect is poor, resulting in some iron impurities and other particles with small diameters that cannot be filtered out, affecting the later cultivation of the liquid strains; therefore, a liquid strain fermentation tank is proposed to solve the above problems.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] See also Figure 1-6 , the utility model provides a technical solution:

[0024] A fermentation tank for liquid bacteria, comprising a fermentation tank body 1, a feed pipe 2 arranged on the top surface of the fermentation tank body 1 and a pipe cover 3 arranged on the top of the feed pipe 2, an annular ring 4 is arranged in the feed pipe 2, and a filter is arranged at the bottom of the annular ring 4. Through the use of the filter, it is convenient to filter iron impurities and other particles in the liquid bacteria entering the fermentation tank body 1, so as to avoid the influence of iron impurities and other particles on the later cultivation of the liquid bacteria, and improve the quality of the liquid bacteria cultivation; a plurality of fixing parts for fixing the filter are evenly arranged on the bottom surface of the annular ring 4; through the use of the fixing parts, it is convenient to install and disassemble the filter, so as to facilitate the replacement of the filter, the operation is simple and convenient, and the work efficiency of replacing the filter is improved.

[0025] The filter element includes an annular mounting plate 5 arranged on the bottom surface of the annular ring 4, and filter net 1 6, filter net 2 7 and filter net 3 8 are respectively arranged in the annular mounting plate 5; through the coordinated use of filter net 1 6, filter net 2 7 and filter net 3 8, it is convenient to filter the liquid bacteria for multiple times, thereby ensuring that the iron impurities and other particles in the liquid bacteria are completely filtered out, ensuring the cultivation of the liquid bacteria.

[0026] The mesh diameter of the filter screen 1 6 is larger than the mesh diameter of the filter screen 2 7 , and the mesh diameter of the filter screen 2 7 is larger than the mesh diameter of the filter screen 3 8 , which is beneficial to the filtration of liquid bacteria.

[0027] The filter net 1 6 , the filter net 2 7 and the filter net 3 8 are all made of gauze material, which improves the quality of the filter net 1 6 , the filter net 2 7 and the filter net 3 8 . Example

[0028] The technical solution is basically the same as that of the first embodiment, except that: Figure 3-Figure 6The fixing part includes a fixing rod 10 arranged on the bottom surface of the annular ring 4, a through hole is opened on the top surface of the annular mounting plate 5 to cooperate with the fixing rod 10, and the bottom of the fixing rod 10 is movably penetrated to the bottom of the annular mounting plate 5, and a rectangular opening 12 is opened at the bottom of the fixing rod 10, and a rotating shaft 11 is rotatably provided at the bottom of the rectangular opening 12, and a fixing plate 13 is provided on the outer wall of the rotating shaft 11; when the fixing plate 13 is perpendicular to the fixing rod 10, the annular mounting plate 5 is fixed, thereby fixing the filter element, and when the fixing plate 13 is parallel to the fixing rod 10, the filter element is released. The operation is simple and convenient, and the work efficiency of replacing the filter element is facilitated.

[0029] In the utility model, an open rubber ring 9 is sleeved on the outer wall of the fixing rod 10 between the fixing plate 13 and the annular mounting plate 5. The use of the open rubber ring 9 facilitates the limiting of the fixing plate 13 to prevent the fixing plate 13 from shaking when the filter element is in use, thereby causing the filter element to be unstable, thereby further improving the stability of the filter element.

[0030] In the present invention, the depth of the rectangular opening 12 is greater than half the length of the fixing plate 13 , so as to facilitate the rotation of the fixing plate 13 .

[0031] Working principle: When the utility model is used, the liquid bacteria are poured into the feed pipe 2, and then the liquid bacteria fall on the filter screen 1 6 through the annular ring 4, and then the large impurities in the liquid bacteria are filtered out by the filter screen 1 6, and other impurities and liquid bacteria pass through the filter screen 1 6 and fall on the filter screen 2 7, and then the medium impurities are filtered by the filter screen 2 7, and the remaining impurities are filtered out by the filter screen 3 8, and finally, the filtered liquid bacteria fall into the fermentation tank body 1, and then the liquid bacteria will be fermented and cultured in the fermentation tank body 1;

[0032] Among them, when there are too many impurities on the filter screen 1 6, the filter screen 2 7 and the filter screen 3 8, the filter element needs to be replaced, specifically: now take out the annular ring 4, then remove the open rubber ring 9, and rotate the fixing plate 13 so that the fixing plate 13 is parallel to the fixing rod 10, release the fixation of the annular mounting plate 5, so that the annular mounting plate 5 is removed, thereby realizing the removal of the filter element, and then replace the new filter element, insert the fixing rod 10 into the annular mounting plate 5, and rotate the fixing plate 13 so that the fixing plate 13 is perpendicular to the fixing rod 10, thereby realizing the fixation of the annular mounting plate 5, and further realizing the installation of the filter element; finally, the open rubber ring 9 is sleeved on the outer wall of the fixing rod 10.

[0033] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
