Description

Technical Field

[0001] The present invention relates to the technical field of microbial fermentation, and specifically to a stirred microbial fermentation system with high dissolved oxygen efficiency. Background Art

[0002] Most aerobic fermentation methods adopt surface liquid fermentation method, porous solid culture fermentation or oxygen-passing deep fermentation, etc., and utilize the decomposition effect of microorganisms in the medium to complete the fermentation process in an oxygen-filled environment.

[0003] For large-scale ventilation fermentation tanks used in fermentation industrial production, the oxygen dissolution rate often becomes a limiting factor in the aerobic fermentation process. The size of dissolved oxygen will have different effects on the formation and yield of fermentation products, and the result directly affects the efficiency of the entire fermentation. If hypoxia, insufficient oxygen supply or poor dissolved oxygen (when the dissolved oxygen is lower than the critical value) occurs during the fermentation production process, it will have a huge impact on the normal growth of microorganisms, resulting in a significant decrease in products, and in severe cases, it will lead to the death of the bacterial cells. Although the existing fermentation tanks are also equipped with stirring devices, on the one hand, the stirring is not sufficient, and on the other hand, a large amount of foam will be generated during the stirring fermentation process. The foam floats up and accumulates above the fermentation broth, making the upper fermentation broth not in sufficient contact with the gas, resulting in an unsatisfactory fermentation effect. Therefore, in view of the above current situation, there is an urgent need to develop a stirred microbial fermentation system with high dissolved oxygen efficiency to overcome the deficiencies in current practical applications.

The other end of the first push rod is fixedly connected to the ring plate 36. Additionally, the pushing and rotating wheel 38 has an elliptical structure. When the supporting column 12 drives the pushing and rotating wheel 38 to rotate, the pushing and rotating wheel 38 pushes the sensing and controlling slide plate 37.

As the pushing and rotating wheel 38 continues to rotate, multiple springs arranged between the ring plate 36 and the closed ring sleeve 34 act together to drive the ring plate 36 to move upward, and a negative pressure is formed inside the closed ring sleeve 34. The closed ring sleeve 34 can only extract the air inside the sewage transportation groove 21 through the sewage extraction pipe 24, thereby completing the extraction of the precipitates sent into the inside of the sewage transportation groove 21. By setting the circulating air extraction and injection assembly 9, it can cooperate with the stirring and dissolved oxygen assembly 7 to achieve continuous air extraction and discharge, and then automatically recycle the precipitates generated after the bubbles are broken, avoiding the accumulation and precipitation of precipitates, and ensuring the fermentation efficiency.
