[0002] Chemical fermentation tanks are equipment used for microbial fermentation production, usually for the production of alcohol, yogurt, soy sauce, lactic acid, antibiotics, etc. These tanks are usually designed to be sealed, and parameters such as temperature, pH value, ventilation rate and stirring speed can be controlled to provide the most suitable environment to promote the growth of microorganisms and the production of products.

[0003] The prior art has the following deficiencies: currently, the inlet of the chemical fermentation tank is sealed with a rubber ring. During long-term use, the rubber ring is prone to wear and aging. At the same time, during the sealed fermentation process, gas is continuously generated in the chemical fermentation tank, and high pressure is formed in the chemical fermentation tank. The high-pressure gas is easy to squeeze the rubber ring and seep out from the gap of the rubber ring. In the long run, it will cause the seal to be not closed enough and the sealing performance to become worse and worse, causing external gas to easily enter the interior of the fermentation tank from the inlet of the fermentation tank, resulting in unsatisfactory fermentation effect and affecting the quality of its fermented products.

[0004] Therefore, it is necessary to invent a chemical fermentation tank with good sealing performance. Utility Model Content

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example 1

[0023] like Figure 1-Figure 3 As shown, a chemical fermentation tank with good sealing performance in the embodiment of the first aspect of the utility model includes a chemical fermentation tank 11 and an annular cover plate 13. The upper end of the inner wall of the chemical fermentation tank 11 is provided with an annular groove, and the inner wall of the chemical fermentation tank 11 is embedded with a first rubber ring 12. Handles 15 are fixedly installed on both sides of the top surface of the annular cover plate 13, and a second rubber ring 14 is fixedly bonded to the bottom surface of the annular cover plate 13. A sealing adsorption cover is inserted into the upper end of the chemical fermentation tank 11, and the annular cover plate 13 can be covered on top of the sealing adsorption cover, and the sealing adsorption cover can adsorb the first rubber ring 12 and the second rubber ring 14.

[0024] In the above embodiment, it should be noted that the first rubber ring 12 and the second rubber ring 14 are both made of rubber, and the handle 15 is used to facilitate lifting the annular cover 13. The raw materials to be fermented are injected into the chemical fermentation tank 11, covered with a sealed adsorption cover, and then the annular cover 13 and the second rubber ring 14 are covered on top of the sealed adsorption cover. By forming a negative pressure in the sealed adsorption cover, the first rubber ring 12 and the second rubber ring 14 are firmly adsorbed, so that the sealed adsorption cover and the chemical fermentation tank 11 are more closely connected, so as to achieve the effect of strengthening the sealing ability of the chemical fermentation tank 11, making the internal fermentation more stable, and ensuring the quality of its fermented products.

[0025] Example 2

[0026] like Figure 3-Figure 5As shown, a chemical fermentation tank with good sealing performance includes all the contents of Example 1. In addition, the sealed adsorption cover includes a hollow cover sheet 21, which is inserted from the upper end of the chemical fermentation tank 11 to the first rubber ring 12, and a vacuum chamber 22 is fixedly installed on the top surface of the hollow cover sheet 21. The lower end of the vacuum chamber 22 is open and passes through the top surface of the hollow cover sheet 21. The inner wall of the vacuum chamber 22 is connected to the inner wall of the hollow cover sheet 21, and the top surface of the vacuum chamber 22 is fixedly installed with a top cover 23. The top cover 23 passes through the top surface of the air extraction chamber 22, and a groove is provided on the top surface of the top cover 23. An opening is provided at the bottom of the groove on the top surface of the top cover 23. A pull rod 24 is inserted and installed in the opening at the bottom of the groove on the top surface of the top cover 23. The lower end of the pull rod 24 passes through the opening of the top cover 23 and extends to the inner wall of the air extraction chamber 22. A rubber sheet 28 is fixedly installed on the lower end of the pull rod 24. The rubber sheet 28 is slidably installed on the inner wall of the air extraction chamber 22, and the outer edge of the rubber sheet 28 is in close contact with the inner wall of the air extraction chamber 22.

[0027] In the above embodiment, it should be noted that the hollow cover piece 21 is a hollow metal disc structure, the diameter of the hollow cover piece 21 is equal to the inner diameter of the chemical fermentation tank 11, and the diameter of the hollow cover piece 21 is smaller than the inner diameter of the first rubber ring 12. A vent is provided on the top surface of the vacuum chamber 22, which can balance the air pressure on the inner wall of the vacuum chamber 22 above the rubber sheet 28 when the rubber sheet 28 slides up and down. By pulling the pull rod 24 upward, the pull rod 24 drives the rubber sheet 28 to slide upward along the inner wall of the vacuum chamber 22, so as to achieve the effect of drawing the air in the hollow cover piece 21 into the vacuum chamber 22.

[0028] Example 3

[0029] like Figure 3-Figure 5 As shown, a chemical fermentation tank with good sealing performance includes all the contents of Example 2. In addition, a rotating shaft 26 is inserted into the upper end of the pull rod 24, and the rotating shaft 26 and the pull rod 24 are perpendicular to each other. The rotating shaft 26 passes through the pull rod 24, and a paddle 25 is sleeved on the upper end of the pull rod 24. Both ends of the rotating shaft 26 pass through the paddle 25. The pull rod 24 and the paddle 25 are rotatably connected through the rotating shaft 26, and the outer edge of the top surface of the hollow cover plate 21 is surrounded by air holes 27, the outer edge of the bottom surface of the hollow cover plate 21 is surrounded by air holes 27, and the side of the hollow cover plate 21 is also surrounded by air holes 27.

[0030] In the above embodiment, it should be noted that the distances between the two vertical sides of the paddle 25 and the rotating shaft 26 are different. When the paddle 25 is rotated perpendicular to the top cover 23, the bottom surface of the paddle 25 is at a certain distance from the top cover 23. By rotating the paddle 25 to make it parallel to the top cover 23, the paddle 25 squeezes the top cover 23 and pries the pull rod 24, causing the pull rod 24 to slide upward.

[0031] Example 4

[0032] like Figure 2, Figure 3 and Figure 5 As shown, a chemical fermentation tank with good sealing performance includes all the contents of Example 2. In addition, the cross-section of the first rubber ring 12 is L-shaped, and the first rubber ring 12 is arranged below the annular groove of the chemical fermentation tank 11. The first rubber ring 12 can wrap the outer edge of the side and bottom surface of the hollow cover plate 21, and the central circular hole of the annular cover plate 13 can be sleeved on the outside of the vacuum cabin 22. The bottom surface of the second rubber ring 14 can wrap the outer edge of the top surface of the hollow cover plate 21.

[0033] In the above embodiment, it should be noted that the first rubber ring 12 and the second rubber ring 14 cover all the air holes 27 on the hollow cover sheet 21. Therefore, when the air in the hollow cover sheet 21 is sucked into the exhaust chamber 22, the external air cannot enter the hollow cover sheet 21 from the air holes 27, resulting in the formation of negative pressure in the hollow cover sheet 21. By forming the negative pressure hollow cover sheet 21, the effect of tightly adsorbing the surfaces of the first rubber ring 12 and the second rubber ring 14 on the air holes 27 is achieved.

[0034] The use process of the utility model is as follows: the technicians in this field inject the raw materials to be fermented into the chemical fermentation tank 11, then cover the hollow cover sheet 21 above the first rubber ring 12, then put the annular cover plate 13 and the second rubber ring 14 on the outside of the vacuum chamber 22 and cover the top surface of the hollow cover sheet 21, rotate the paddle 25 to make it parallel to the top cover 23, the paddle 25 squeezes the top cover 23 and pries the pull rod 24 to make the pull rod 24 slide upward, and the pull rod 24 drives the rubber sheet 28 along the inner wall of the vacuum chamber 22 Slide upward to draw the air in the hollow cover sheet 21 into the exhaust chamber 22. Since the first rubber ring 12 and the second rubber ring 14 cover all the air holes 27 on the hollow cover sheet 21, when the air in the hollow cover sheet 21 is drawn into the exhaust chamber 22, the external air cannot enter the hollow cover sheet 21 through the air holes 27, resulting in negative pressure in the hollow cover sheet 21. Through the hollow cover sheet 21 that forms negative pressure, the surfaces of the first rubber ring 12 and the second rubber ring 14 are tightly adsorbed on the air holes 27 to complete the sealing.

[0035] The above is only a preferred embodiment of the utility model. Any person skilled in the art may modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
