Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, specifically a composite microbial fermentation tank with self-cleaning function. Background Technology

[0002] Compound microbial fermentation technology is widely used in food, medicine, environmental protection and other fields. Its core equipment is the fermenter. The fermenter needs to maintain stable environmental parameters such as temperature, pH value and dissolved oxygen to ensure the synergistic growth of multiple strains. However, if the culture medium residue, microbial mycelium and metabolites (such as polysaccharides and protein crusts) left in the tank after fermentation are not cleaned thoroughly, it can easily lead to cross-contamination of strains during the next fermentation and affect product quality. Therefore, it is necessary to clean the compound microbial fermenter regularly.

[0003] A search revealed a patent, CN212451400U, which discloses a composite microbial fermentation tank that is easy to clean. The tank includes a tank body, a lid, a feeding pipe, a discharge pipe, a control valve, support legs, and a cleaning mechanism. The lid is located on the top of the tank body, with the feeding pipe fixedly connected to the right side of the lid. The discharge pipe is fixedly connected to the midpoint of the bottom of the tank body, and the control valve is fixedly installed on the left side of the discharge pipe. Support legs are fixedly connected to the four corners of the bottom of the tank body. The cleaning mechanism, including a drive motor, is fixedly connected to the lid. This invention, through the coordinated operation of the tank body, lid, feeding pipe, discharge pipe, control valve, support legs, and cleaning mechanism, achieves easy cleaning. The cleaning process eliminates the need for manual handheld cleaning equipment, simplifying operation, saving time and labor, greatly reducing the workload of workers, and providing good cleaning results. Its simple structure and strong practicality make it worthy of promotion.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents describe a scraper that rotates with the drive shaft, working in conjunction with a cleaning mechanism to clean the inner wall of the tank. However, in reality, with prolonged use, the scraper, which is in close contact with the inner wall of the tank, will wear down. When the scraper wears down, a gap will appear between the scraper and the inner wall of the tank. At this point, the cleaning effect of the scraper on the inner wall of the tank will decrease, thereby reducing the self-cleaning effect of the fermenter. Therefore, there is an urgent need in the art to improve the composite microbial fermenter to overcome the shortcomings of the prior art. Utility Model Content

[0029] Example 1

[0030] Please see Figures 1-6 A self-cleaning composite microbial fermenter includes a tank body 1. The upper part of the tank body 1 has a detachable and sealable cover plate 2. The cover plate 2 has an inlet 3 communicating with the inside of the tank body 1. The lower part of the tank body 1 has an outlet pipe 4 communicating with the inside of the tank body 1. A rotating shaft 5 is located inside the tank body 1. A drive motor 6 is fixedly installed on the upper part of the cover plate 2. The output end of the drive motor 6 is fixedly installed on the upper end of the rotating shaft 5. Several fixing brackets 7 are fixedly installed on the side of the rotating shaft 5. Several stirring blades 8 are fixedly installed on the opposite sides of the fixing brackets 7. Several cleaning rods 9 are located inside the tank body 1, abutting against the side and inner wall of the tank body 1. Several springs 10 are located between the cleaning rods 9 and the fixing brackets 7. The tension of the springs 10 pushes the cleaning rods... The cleaning rod 9 abuts against the inner wall of the tank 1. The lower part of the sealing cover 2 is equipped with a high-pressure flushing unit that fully covers the inside of the tank 1. The high-pressure flushing unit includes an annular pipe 13 fixedly installed at the lower part of the sealing cover 2. A conveying pipe 14 that is connected to the annular pipe 13 is installed through and fixedly installed on the sealing cover 2. Several high-pressure nozzles 15 that are connected to the annular pipe 13 and are in multiple directions are fixedly installed at the lower part of the annular pipe 13. Several hollow columns 11 are provided on one side of the fixing frame 7. A connecting column 12 with one end located in the hollow column 11 is fixedly connected to one side of the cleaning rod 9. The spring 10 is adapted to the connecting column 12. The side of the tank 1 is equipped with a main controller 20 that is electrically connected to the drive motor 6. The side of the tank 1 is equipped with a heating device and a heating module 21 that is electrically connected to the heating device.

[0031] In this embodiment, a feed pipe with a valve (not shown in the figure) is fixedly installed at the feed inlet 3 on the sealing cover plate 2. Microbial inoculum and culture medium are introduced through the feed pipe, and the valve on the feed pipe is closed. The main controller 20 starts the drive motor 6, and the output end of the drive motor 6 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives several fixed frames 7 to rotate, and the fixed frames 7 drive several stirring blades 8 to rotate. The rotating stirring blades 8 mix the materials in the tank 1. The heating module 21 turns on the heating device installed in the tank 1. The tank 1 is equipped with a temperature detection device for detecting the internal temperature of the tank 1. The temperature inside the tank 1 is monitored in real time to maintain a constant temperature, realizing the fermentation of the compound microorganisms. When the fermentation is complete... Afterwards, the valve on the discharge pipe 4 is opened to discharge the fermented material through the discharge pipe 4. After the material is completely discharged, the output end of the drive motor 6 still drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the fixed frame 7 and the cleaning rod 9 to rotate simultaneously. The cleaning water delivery pump connected to the delivery pipe 14 is turned on and the cleaning water is delivered to the annular pipe 13 through the delivery pipe 14. The water is then sprayed out through several high-pressure nozzles 15 at multiple angles. The high-pressure nozzles 15 wash the inner wall of the tank 1, the rotating shaft 5, and several stirring blades 8. The cleaning rods 9 clean the inner wall of the tank 1. The spring 10 always has a tension pushing the connecting column 12, so that one side of the cleaning rod 9 is pressed tightly against the inner wall of the tank 1, thus maintaining the cleaning effect on the inner wall of the tank 1.

The second sealing ring 17 is elastic. The first sealing ring 16 and the second sealing ring 17 prevent a large amount of impurities from entering the hollow column 11, which would cause the spring 10 to fail. The side of the fixing frame 7 is provided with several connecting holes 18. One end of the hollow column 11 is threaded into the connecting hole 18, which facilitates the installation or subsequent maintenance of the hollow column 11 and the cleaning rod 9.
