Description

Technical Field

[0001] The utility model relates to the field of fermentation tanks, in particular to a closed drug fermentation tank. Background Art

[0002] Fermentation tank is one of the most important equipment in bioengineering, which provides an ideal environment for the growth and reproduction of microorganisms. Its basic structure includes tank body, agitator, cooling device, heating device, air distribution device, temperature and pressure control system, etc. The tank body is the main part of the fermentation tank, usually made of stainless steel or other corrosion-resistant materials, used to contain the fermentation liquid. The function of the agitator is to mix the fermentation liquid evenly to ensure the uniform growth of microorganisms. The cooling device and heating device are used to adjust the temperature of the fermentation liquid to meet the growth requirements of different microorganisms. The air distribution device is used to supply sufficient oxygen to the fermentation liquid to meet the breathing needs of microorganisms. The temperature and pressure control system is used to accurately control the temperature and pressure during the fermentation process to ensure the normal growth of microorganisms.

[0003] In the prior art, some drugs often require the use of fermentation tanks during the production process, through which materials are closed and fermented in the tank body. However, in actual use, the existing fermentation tanks can only stir the inside of the tank body due to the relatively single function of the agitator. During stirring, the raw materials are easily attached to the inner wall of the tank body. During and after stirring, the attachments on the inner wall of the tank body cannot be scraped and cleaned, resulting in the need for manual cleaning using cleaning tools. The operation is cumbersome, time-consuming and labor-intensive, which not only brings inconvenience to the cleaning operation of the fermentation tank, but also causes waste of raw materials. At the same time, the fermented materials are prone to blockage in the feed port during discharge, which requires manual unblocking, thereby reducing work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1 - Figure 4 As shown, in this embodiment, in order to use the stirring mechanism 5 to stir the material in the tank body 1, the residue attached to the inner wall of the tank body 1 can be scraped and cleaned, and the feed port 3 can be prevented from being blocked during discharge, and the specific use principle of the stirring mechanism 5 in conjunction with the fermentation tank is as follows:

[0021] The compression spring 14 installed at the bottom end of the fixed ring 13 will always perform an elastic downward extension operation and push the movable ring 15 downward. The movable ring 15 will move downward along the stirring shaft 7 through the sliders 22 installed on both sides of the inner wall of the ring, and the sliders 22 will slide in the slide grooves 11 opened on both sides of the outer wall of the stirring shaft 7. At this time, because the rotating rods 21 installed on the front and rear sides of the left and right ends of the connecting rod 20 are respectively movably installed in the rotating holes 19 opened on both sides of the inner wall of the concave block 18 installed on the upper inner wall of the scraper plate 16 and on one side of the outer wall of the movable ring 15, the rotating rod 21 will rotate in the rotating hole 19, and the movable ring 15 on both sides The connecting rod 20 is unfolded in both directions, and the angle formed by the symmetrical connecting rods 20 will gradually increase. In this process, the connecting rod 20 will move the scraper plate 16 outward until the scraper plate 16 is tightly attached to the inner wall of the tank body 1 under the elastic action of the compression spring 14, and the scraper plate 16 can always be tightly attached to the inner wall of the tank body 1 under the elastic action of the compression spring 14. At the same time, when the scraper plate 16 moves outward, the telescopic rod 17 installed at the bottom of the inner wall of the scraper plate 16 will move from the telescopic cylinder 12 installed at the bottom of the outer wall of both sides of the stirring shaft 7 to the outside. When the motor 6 drives the output end to drive When the stirring shaft 7 installed at the bottom rotates in the tank body 1, the stirring rod 8 installed on the outer wall of the stirring shaft 7 will stir the material in the tank body 1 to improve the fermentation efficiency. At this time, as the stirring shaft 7 rotates, the scraper plate 16 that is closely attached to the inner wall of the tank body 1 will rotate with the rotation of the stirring shaft 7, and the material attached to the inner wall of the tank body 1 can be effectively scraped off during the rotation process, thereby avoiding the material from adhering to the inner wall of the tank body 1 and causing inconvenience for subsequent cleaning operations. Similarly, when cleaning the inner wall of the tank body 1 later, the remaining attachments on the inner wall can also be quickly scraped off for cleaning. When discharging, due to the installation of the extension rod 9 At the bottom end of the stirring shaft 7, the stirring shaft 7 will drive the extension rod 9 to rotate, and the extension rod 9 will drive the spiral blade 10 installed on the outer wall to rotate. The spiral blade 10 will continuously transport the material in the tank body 1 downward during the rotation, so that the material is finally discharged through the feed port 3. In this way, the problem of material clogging in the feed port 3 caused by only discharging through the feed port 3 can be avoided, thereby not only achieving the purpose of quickly cleaning the fermentation tank, but also achieving the purpose of avoiding clogging when the fermentation tank is discharged, thereby improving work efficiency and enabling the stirring mechanism 5 to have the function of cleaning the inner wall of the tank body 1 and preventing the feed port 4 from being blocked.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, various improvements may be made to the present invention and its components may be replaced by equivalents, or some of its technical features may be replaced by equivalents without departing from the scope of the present invention. All that is within the spirit and principles of the present invention should be included in the protection scope of the present invention.
