Description

Technical Field

[0001] The utility model relates to the field of bacillus aqueous solution production, in particular to a microbial fermentation device for the production of bacillus aqueous solution. Background Art

[0002] Bacillus spores include genera such as Bacillus, Sporolactobacillus, Clostridium, Desulfurized Enterococcus, and Sporosarcina. They are highly resistant to harmful external factors and are widely distributed, found in soil, water, air, and the intestinal tract of animals. During Bacillus fermentation, an appropriate oxygen level must be maintained, typically through aeration and stirring. Fermenters are industrial devices used for microbial fermentation, while biopesticide fermenters are specifically designed for biopesticide production. Their main bodies are typically cylindrical, constructed of stainless steel plates, which create dead zones for stirring. Larger fermenters can also lack sufficient oxygen at the bottom. During Bacillus fermentation, large amounts of sterile air are introduced from the bottom of the fermenter. This, combined with the large amounts of gas produced during microbial growth and the presence of sugars, proteins, and other substances in the fermentation broth, can cause significant foaming during the culture process. If not promptly eliminated, this foaming can affect the normal growth of the bacteria.

[0003] According to the public patent 201920303581.4, a bacillus fermentation device can be known, including a support base and a fermentation tank, characterized in that: the fermentation tank includes an inner tank and an outer tank, a sandwich is formed between the inner tank and the outer tank, an inlet and a outlet are provided on the fermentation tank, an oxygen tank and a motor are provided on the left side of the support base, a belt bearing is provided on the upper end of the support base, the fermentation tank is arranged on the belt bearing, an aeration pipe is inserted into the interior of the fermentation tank, the aeration pipe is connected to the oxygen tank, an oxygen supply mechanism is provided on the aeration pipe, and a bubble breaking needle is provided on the top of the oxygen supply mechanism, which can evenly oxygenate the fermentation tank and avoid hypoxia caused by accumulation of bacteria, which is beneficial to the reproduction of aerobic bacillus; the setting of the feeding mechanism can make the oxygen evenly distributed, and in the process of realizing the process of the utility model During the process, the inventors found that there are at least the following problems in the prior art that have not been solved: although the fermentation tank can be evenly oxygenated and the accumulation of bacteria can be avoided to cause hypoxia, which is conducive to the reproduction of aerobic Bacillus; the setting of the feeding mechanism can make the oxygen evenly distributed; the feed liquid leaks into the tank through the filter cover, which can increase the area of ​​contact with oxygen and further promote the dissolved oxygen of the feed liquid. However, during use, the traditional microbial fermentation device for the production of Bacillus aqueous solution, because the surface of the tank body is connected to multiple pipes, the tank body will be restricted by the pipes during the rotation process, resulting in the tank body being unable to rotate effectively. Moreover, due to the spacing between the multiple defoaming needles, bubbles are located between the multiple defoaming needles, and the defoaming effect is not very good. For this reason, it is necessary to design a new technical solution to solve this problem. Utility Model Content

[0022] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0023] Example 1: A microbial fermentation device for producing a bacillus aqueous solution, see Figures 1 to 3 , including a fermentation cylinder 1, and also including: a stirring tube 207, which is arranged in the fermentation cylinder 1, and one end of the stirring tube 207 is a sealed structure; a fermentation mechanism, which is connected to the upper and lower ends of the stirring tube 207, and the fermentation mechanism includes a plurality of tubes 208, and the plurality of tubes 208 are respectively connected to the upper and lower ends of the stirring tube 207, and a plurality of through holes 209 are opened on the outer wall of the stirring tube 207, and a defoaming needle 210 is fixed at one end of the tube 208; the other end of the stirring tube 207 passes through the fermentation cylinder 1 and is fixedly connected to a rotary joint 202 , the end of the rotary joint 202 away from the stirring tube 207 is connected to the air pipe 201, and the end of the air pipe 201 away from the rotary joint 202 is connected to the air pump 2. First, turn on the motor 206, the motor 206 drives the motor shaft 205, the motor shaft 205 drives the second gear 204, the second gear 204 drives the first gear 203 to rotate, the first gear 203 will drive the rotary joint 202 to rotate, the rotary joint 202 will drive the stirring tube 207 to rotate, and the stirring tube 207 drives the tube body 208 and When the defoaming needle 210 rotates and the stirring tube 207 and the tube body 208 rotate, the air pump 2 can be turned on. The air pump 2 will draw gas into the stirring tube 207 and discharge it through multiple through holes 209 on the surface of the tube body 208, thereby evenly distributing oxygen at different positions inside the fermentation cylinder 1. At the same time, the defoaming needles 210 on the surface of the tube body 208 will also defoam during the rotation process. Spiral blades 301 are also provided at both ends of the stirring shaft. The rotation of the spiral blades 301 can drive the liquid on both sides to rush toward the middle, thereby breaking the bubbles in the fermentation liquid, further improving the defoaming effect, and solving the problem of traditional microbial fermentation devices for the production of bacillus aqueous solutions. Since the surface of the tank body is connected to multiple pipes, the tank body will be restricted by the pipes during rotation, resulting in the tank body being unable to rotate effectively. Moreover, due to the spacing between the multiple defoaming needles 210, the bubbles located between the multiple defoaming needles 210 have a poor defoaming effect.

During the rotation of the stirring shaft, the fixed frame plate 211 and the defoaming mesh 212 will be driven to rotate at the same time. The bubbles will pass through the gaps in the defoaming mesh 212, and the bubbles in a large area will be eliminated through multiple gaps, further improving the defoaming effect.

[0030] When using a microbial fermentation device for producing a bacillus aqueous solution, first turn on the motor 206, the motor 206 drives the motor shaft 205, the motor shaft 205 drives the second gear 204, the second gear 204 drives the first gear 203 to rotate, the first gear 203 drives the rotary joint 202 to rotate, the rotary joint 202 drives the stirring tube 207 to rotate, the stirring tube 207 drives the tube body 208 and the defoaming needle 210 to rotate, and during the rotation of the stirring tube 207 and the tube body 208, the air pump 2 can be turned on, and the air pump 2 will draw gas into the stirring tube 207 and discharge it through the multiple through holes 209 on the surface of the tube body 208. Thereby, oxygen is evenly distributed at different positions inside the fermentation cylinder 1. At the same time, the defoaming needles 210 on the surface of the tube body 208 will also defoam during the rotation. Spiral blades 301 are also provided at both ends of the stirring shaft. The rotation of the spiral blades 301 can drive the liquid on both sides to rush toward the middle, thereby breaking the bubbles in the fermentation liquid, further improving the defoaming effect. During the rotation of the stirring shaft, the fixed frame plate 211 and the defoaming mesh 212 will also be driven to rotate. The bubbles will pass through the gaps in the defoaming mesh 212 and eliminate bubbles in a large area through multiple gaps, further improving the defoaming effect.
