It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope of the utility model.

[0019] For example, Figures 1-4As shown, a good sealing liquor raw material fermentation tank, including fermentation tank main body 1, the inside of fermentation tank main body 1 is provided with fermentation cavity, the upper side of fermentation tank main body 1 is provided with and communicates with the feed inlet 2 of fermentation cavity, liquor raw material can enter the inside of fermentation tank main body 1 through feed inlet 2 and carry out fermentation, the upper side of fermentation tank main body 1 and the outside of feed inlet 2 are fixedly connected with a first sealing ring 3, the inside of first sealing ring 3 is provided with the first annular groove 7 of upper side opening, the inside of first sealing ring 3 and the side of first annular groove 7 are provided with and communicate with the second annular groove 9 of first annular groove 7;

[0020] The upper side of fermentation tank main body 1 is also rotatably connected with rotating plate 5, the sealing door 4 is fixedly connected on rotating plate 5, the sealing door 4 can be rotatably connected to the upper side of first sealing ring 3 and abut against first sealing ring 3, so that the sealing door 4 can seal feed inlet 2, the inner side of first sealing ring 3 is fixedly connected with a second sealing ring 8 opposite to first annular groove 7, when the sealing door 4 is rotated to the upper side of first sealing ring 3, the second sealing ring 8 is installed in the inside of first annular groove 7, and the side of second sealing ring 8 is provided with annular mounting groove 14, the annular mounting groove 14 is provided on the inner side or the outer side of second sealing ring 8, the third sealing ring 10 is installed in the inside of annular mounting groove 14, the third sealing ring 10 can extend to the inside of second annular groove 9, the sealing property between second sealing ring 8 and first sealing ring 3 makes the liquor raw material fermentation tank have good sealing property.

[0021] At the same time, as shown, Figures 1-3 The side of second annular groove 9 away from first annular groove 7 is provided with wave-shaped part 12, when third sealing ring 10 abuts against wave-shaped part 12, the side wall of third sealing ring 10 can be extruded and shaped by wave-shaped part 12, so that the side wall of third sealing ring 10 and wave-shaped part 12 forms wave-shaped sealing part 13, so that the sealing property between third sealing ring 10 and first sealing ring 3 can be further improved by the cooperation of wave-shaped part 12 and wave-shaped sealing part 13.

[0022] Wherein, the third sealing ring 10 can be pushed into the inside of second annular groove 9 by pushing mechanism, or the third sealing ring 10 can be automatically extended into the inside of second annular groove 9 by the expansion deformation of third sealing ring 10, the third sealing ring 10 is automatically extended into the inside of second annular groove 9 by the expansion deformation of third sealing ring 10 in this technical solution, and the specific is Figures 1-3As shown, a ring-shaped cavity 11 is arranged inside the third sealing ring 10, and the third sealing ring 10 can be made of rubber or latex. The sealing door 4 is fixedly connected with a gas pressure adjusting mechanism on the outside. The gas pressure adjusting mechanism is connected with the ring-shaped cavity 11 in the third sealing ring 10 through a gas guide pipe. Thus, the gas pressure in the ring-shaped cavity 11 can be adjusted by the gas pressure adjusting mechanism to control the expansion or contraction of the third sealing ring 10. When the third sealing ring 10 is in the contracted state, it can be contracted into the ring-shaped mounting groove 14. When the third sealing ring 10 is expanded, it can be expanded to extend into the second ring-shaped groove 9.

[0023] As shown in Figure 1 and Figure 4 The gas pressure adjusting mechanism comprises a gas container 15 fixedly connected to the upper side of the sealing door 4. One end of the gas container 15 is fixedly connected with an electric push rod 16. The piston rod of the electric push rod 16 extends into the gas container 15 and is fixedly connected with a gas pushing plate 17. The gas pushing plate 17 is slidingly connected in the gas container 15, and the outer side of the gas pushing plate 17 is provided with a rubber ring. The rubber ring is in interference fit with the inner wall of the gas container 15. The end of the gas container 15 away from the electric push rod 16 is connected with the gas guide pipe. At this time, the gas in the gas container 15 can be pushed into the ring-shaped cavity 11 or the gas in the ring-shaped cavity 11 can be sucked into the gas container 15 by starting the electric push rod 16 to push the gas pushing plate 17. Thus, the gas pressure in the ring-shaped cavity 11 can be controlled more simply to control the expansion or contraction of the third sealing ring 10.

[0024] Further, the piston rod of the electric push rod 16 can be fixedly connected with a connecting plate 18. A return spring 19 is fixedly connected between the gas pushing plate 17 and the connecting plate 18. When the gas pressure in the third sealing ring 10 decreases, the return spring 19 can pressurize the gas pushing plate 17 to push the gas in the gas container 15 into the ring-shaped cavity 11. Thus, the gas pressure in the ring-shaped cavity 11 can be maintained for a long time to adapt to the long fermentation period of the raw liquor.

[0025] As shown in Figures 1-2 The rotating plate 5 can be fixedly connected with a first electric push rod 6. The output end of the first electric push rod 6 is fixedly connected with the sealing door 4. At this time, after the rotating plate 5 is rotated, the sealing door 4 is located on the upper side of the first sealing ring 3. Then, the first electric push rod 6 can be started to push the sealing door 4 from the upper side of the first sealing ring 3 to the first sealing ring 3. When the second sealing ring 8 enters the first ring-shaped groove 7, it can move linearly. Thus, the second sealing ring 8 and the first ring-shaped groove 7 can keep a small gap, and a large gap does not need to be reserved to match the rotation of the second sealing ring 8.
