Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of biological fermentation, and in particular relates to a defoaming device for a high-density fermentation tank. Background Art
[0002] Alcohol is a biomass energy widely used in chemical, biological, and pharmaceutical industries. Its production methods mainly include chemical synthesis and biological fermentation. Biological fermentation refers to the process of using microorganisms to produce alcohol products. High-density fermentation for alcohol production is a new biochemical engineering technology that achieves high yield and low emissions by increasing the density of target microorganisms in the fermentation liquid.
[0003] The high-density alcohol production process will produce a large amount of carbon dioxide. The discharge of carbon dioxide needs to pass through the fermentation mash layer containing alcohol, so it is saturated with alcohol vapor to form bubbles. As the fermentation process progresses, the continuous accumulation and discharge of bubbles will inevitably take away part of the alcohol in the mash, causing the "liquid leakage" phenomenon.
[0004] At the same time, in the high-density alcohol fermentation process, due to the high yeast density in the fermentation tank, the overflow of bubbles will carry out the bacteria in the fermentation tank, causing an imbalance in the fermentation process and waste of bacteria, and even leading to infection by miscellaneous bacteria and causing the failure of the alcohol product fermentation process.
[0005] Commonly used mechanical defoaming methods and defoaming agents can eliminate bubbles in general fermentation processes, but it is still difficult to defoam the large amount of foam produced during high-density alcohol fermentation, and it is difficult to achieve an ideal defoaming effect. Utility Model Content
[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a high-density fermentation tank defoaming device that can overcome the above problems or at least partially solve the above problems.
[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a high-density fermentation tank defoaming device, including a tank body, the side end of the tank body is fixedly installed and connected to a feeding pipe, the upper cover of the tank body is equipped with a sealing cover, a rotating motor is fixedly installed on the sealing cover, a rotating plate is rotatably installed in the sealing cover, a rotating shaft column is fixedly installed on the bottom end of the rotating plate, an arc plate is fixedly installed on the rotating shaft column, a U-shaped filter plate is fixedly installed on the arc plate, a plurality of filter holes are provided on the U-shaped filter plate, and the U-shaped filter plate is against the inner wall surface of the tank body.
[0008] In order to stir the U-shaped filter plate, preferably, a stirring shaft is rotatably installed in the U-shaped filter plate, a plurality of stirring blades are fixedly installed on the stirring shaft, a rotating shaft sleeve is fixedly installed on the top end of the stirring shaft, and the rotating shaft sleeve is rotatably connected to the rotating plate.
[0009] In order to control the rotation of the stirring shaft, further, a fixed gear ring is fixedly installed in the cover, and a rotating gear matching the fixed gear ring is fixedly installed on the rotating shaft sleeve, and the rotating gear is engaged with the fixed gear ring.
[0010] In order to improve the stirring effect, further, a plurality of microholes are provided on the stirring blade.
[0011] In order to make the liquid in the tank body flow along the convex surface of the arc plate to the U-shaped opening of the U-shaped filter plate, preferably, the U-shaped opening of the U-shaped filter plate faces the convex surface of the arc plate.
[0012] In order to observe the defoaming situation in the tank body, preferably, an observation window is fixedly installed on the tank body.
[0013] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model is a high-density fermentation tank defoaming device, which allows high-density bio-alcohol and defoaming agent to be pushed by the arc plate in the tank body, and flow along the convex surface of the arc plate to the U-shaped filter plate. Because the area where the U-shaped filter plate is located is the place where the distance between the arc plate and the inner wall of the tank body is the smallest, it is the place where the hydraulic pressure in the tank body is the largest. The liquid will flow to the high hydraulic pressure, and then after being stirred by the stirring shaft, the defoaming agent will be evenly and quickly dissolved in the high-density bio-alcohol, thereby achieving a defoaming effect and improving the defoaming efficiency.

The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0023] Example:
[0024] Reference Figure 1-5 As shown, a defoaming device for a high-density fermentation tank comprises a tank body 1, a side end of the tank body 1 is fixedly installed and connected to a feeding pipe 101, a sealing cover 2 is installed on the upper cover of the tank body 1, a rotating motor 3 is fixedly installed on the sealing cover 2, a rotating plate 4 is rotatably installed in the sealing cover 2, a rotating shaft column 5 is fixedly installed on the bottom end of the rotating plate 4, an arc plate 6 is fixedly installed on the rotating shaft column 5, a U-shaped filter plate 7 is fixedly installed on the arc plate 6, a plurality of filter holes 701 are provided on the U-shaped filter plate 7, and the U-shaped filter plate 7 is against the inner wall surface of the tank body 1.
[0025] A stirring shaft 8 is rotatably installed in the U-shaped filter plate 7, and a plurality of stirring blades 801 are fixedly installed on the stirring shaft 8. A rotating shaft sleeve 11 is fixedly installed on the top of the stirring shaft 8, and the rotating shaft sleeve 11 is rotatably connected to the rotating plate 4. A fixed gear ring 9 is fixedly installed in the cover 2, and a rotating gear 10 matching the fixed gear ring 9 is fixedly installed on the rotating shaft sleeve 11. The rotating gear 10 is engaged with the fixed gear ring 9, and a plurality of micropores 802 are provided on the stirring blade 801. When the rotating plate 4 rotates, the rotating shaft sleeve 11 and the stirring shaft 8 are also driven to revolve in the tank body 1. At the same time, the rotating gear 10 is engaged with the fixed gear ring 9, so that the rotating gear 10 is also rotating during the revolution, so that the stirring shaft 8 not only revolves but also rotates, so that the stirring blade 801 on the stirring shaft 8 rotates in the U-shaped filter plate 7, thereby improving the stirring effect, and the micropores 802 improve the uniform stirring effect.
[0026] The U-shaped opening of the U-shaped filter plate 7 faces the convex surface of the arc-shaped plate 6. When the arc-shaped plate 6 rotates in the tank body 1, the convex surface will face the liquid flow. The liquid flow flows along the convex surface of the arc-shaped plate 6 toward the U-shaped filter plate 7, impacting the defoaming agent in the U-shaped filter plate 7, causing the defoaming agent to quickly dissolve in the solution.
[0027] An observation window 12 is fixedly mounted on the tank body 1 , through which the defoaming condition in the tank body 1 can be observed, and the input of the defoaming agent and the rotation speed of the rotating motor 3 can be controlled.
[0028] The utility model conveys high-density bioethanol and defoaming agent into the tank body 1 through the feed pipe 101, starts the rotating motor 3, causes the arc plate 6 and the U-shaped filter plate 7 to revolve in the tank body 1, and the stirring shaft 8 not only revolves but also rotates in the U-shaped filter plate 7. The high-density bioethanol and defoaming agent flow along the convex surface of the arc plate 6 into the U-shaped filter plate 7, and are stirred and mixed by the rapidly rotating stirring shaft 8 in the U-shaped filter plate 7. Finally, under the action of hydraulic pressure, they quickly pass through the micropores 802 and the filter holes 701, so that the high-density bioethanol and the defoaming agent are evenly and quickly dissolved, thereby achieving the defoaming effect.
