[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a microbial fermentation device capable of filtering, including a microbial fermentation device body, and a second discharge pipe 3 is provided at the bottom of the microbial fermentation device body. A sealing ring 2 is attached to the bottom of the second discharge pipe 3, and the bottom of the sealing ring 2 is attached to the top of the first discharge pipe 1. Annular grooves 5 are provided on the inner side of the top of the first discharge pipe 1 and the inner side of the bottom of the second discharge pipe 3. The inside of the annular grooves 5 is engaged with the side of the top of the filter screen 6. The first discharge pipe 1 and the second discharge pipe 3 are fixedly connected by a quick disassembly and installation mechanism.

[0021] The top of the first discharge pipe 1, the bottom of the second discharge pipe 3, and the filter screen 6 are all designed as hemispherical structures. The diameters of the top of the first discharge pipe 1, the bottom of the second discharge pipe 3, and the filter screen 6 are all larger than the diameters of the bottom of the first discharge pipe 1 and the top of the second discharge pipe 3. This design significantly increases the actual filtration area of ​​the filter screen 6 compared to traditional flat filter screens. At the same time, the hemispherical structure helps the fermentation liquid to converge towards the center under the action of gravity, accelerating the filtration process, reducing the residence time of impurities on the filter screen 6, and reducing the probability of clogging.

[0022] The quick disassembly and assembly mechanism includes an annular plate 7. The annular plate 7 is threaded onto the outer side of the second discharge pipe 3. An annular limiting groove 8 is formed inside the annular plate 7, and an annular through groove 9 is formed at the bottom of the annular limiting groove 8. The diameter of the annular through groove 9 is smaller than the diameter of the annular limiting groove 8. A circular plate 10 is slidably installed inside the annular limiting groove 8. A pull rod 11 is fixed at the bottom center of the circular plate 10. The lower end of the pull rod 11 passes through the annular through groove 9, the bottom side of the second discharge pipe 3, and the side of the sealing ring 2 in sequence, and is fixedly connected to the top side of the first discharge pipe 1. The pull rod 11 is slidably connected to the annular through groove 9, the bottom side of the second discharge pipe 3, and the side of the sealing ring 2. This mechanism can achieve quick separation and assembly of the first discharge pipe 1 and the second discharge pipe 3 by simply rotating the annular plate 7. Compared with the existing complex disassembly structure, the operation is simpler and faster.

[0023] Push rods 12 are fixed to the outer wall of the annular plate 7, and the push rods 12 are distributed at equal angles about the central axis of the annular plate 7. The push rods 12 are designed to facilitate the operator to apply force and rotate the annular plate 7 more easily, thereby improving the convenience of operation.

[0024] There are two circular plates 10 and two tie rods 11 symmetrically distributed about the central axis of the annular plate 7. The two symmetrically distributed circular plates 10 and tie rods 11 ensure that the first discharge pipe 1 and the second discharge pipe 3 are subjected to uniform force when connected, thus ensuring the stability and sealing of the connection.

[0025] The second discharge pipe 3 is equipped with a manual valve 4, which can flexibly control the discharge of fermentation liquid, making it convenient to open or close the discharge operation according to actual needs during the fermentation process.

[0026] Working principle: During use, after fermentation is complete, open the manual valve 4 on the second discharge pipe 3, and the fermentation liquid flows from the main body of the microbial fermentation device into the second discharge pipe 3. Since the first discharge pipe 1, the second discharge pipe 3, and the filter screen 6 are all hemispherical structures, the fermentation liquid will quickly converge towards the center of the filter screen 6 under the action of gravity. When passing through the hemispherical filter screen 6, the microbial cells, unreacted raw material particles, and other impurities are intercepted, and the pure fermentation product is discharged through the first discharge pipe 1.

[0027] When the filter screen 6 becomes clogged or needs replacement after a period of use, the operator can hold the push rod 12 on the annular plate 7 and rotate the annular plate 7. As the annular plate 7 rotates and moves downward outside the second discharge pipe 3, the circular plate 10 in the annular limiting groove 8 will slide downward under the constraint of the annular limiting groove 8. The circular plate 10 pushes the first discharge pipe 1 downward through the pull rod 11, so that the first discharge pipe 1 and the second discharge pipe 3 are separated. Then the filter screen 6 can be removed from the inside of the first discharge pipe 1 for cleaning or replacement. During installation, the top edge of the filter screen 6 is inserted into the annular groove 5 of the first discharge pipe 1, and then the annular plate 7 is rotated in the opposite direction to move the annular plate 7 upward, which drives the circular plate 10, the pull rod 11 and the first discharge pipe 1 to move upward, thereby tightly connecting the first discharge pipe 1 and the second discharge pipe 3, completing the installation, and can continue to be put into use.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
