Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 4In an embodiment of the present invention, a fermentation tank with a built-in defoaming and gas-liquid separation device includes a tank body 1, a base 3 is installed at the lower end of the tank body 1, a discharge pipe 2 is installed at the lower end of the side wall of the tank body 1, a feed pipe 4 is installed on the side wall of the tank body 1 above the discharge pipe 2, a motor 10 is installed at the center position of the upper end of the tank body 1, and a rotating rod 18 is installed at the output end of the motor 10, and the end of the rotating rod 18 away from the motor 10 passes through the top of the tank body 1 and is rotatably connected to the center position of the bottom of the tank body 1, and a plurality of second stirring rods 19 are installed on the side wall of the rotating rod 18 between the discharge pipe 2 and the feed pipe 4. A defoaming mechanism for eliminating foam is provided inside the tank body 1 above the feed pipe 4, and a condensing mechanism for separating gas and liquid after defoaming is provided on the top of the tank body 1.

[0027] The defoaming mechanism includes a conical fixing plate 15, which is mounted on the inner wall of the tank body 1 above the feed pipe 4. The opening at the upper end of the conical fixing plate 15 is sleeved on the rotating rod 18. The upper end of the conical fixing plate 15 is mounted with a first electric heating plate 14, and the lower end of the conical fixing plate 15 is mounted with a heat insulation plate 16. A plurality of electric heating columns 6 are mounted in a circumferential array on the inner wall of the tank body 1 above the first electric heating plate 14. The side walls of the electric heating columns 6 and the upper end of the first electric heating plate 14 are both provided with The purpose of the frosted layer is to keep the side walls of the electric heating column 6 and the upper end of the first electric heating plate 14 rough and dry, so as to facilitate the foam to break. The side walls of the rotating rod 18 between the electric heating column 6 and the first electric heating plate 14 are installed in a circular array with the first stirring rod 5 for evenly distributing the foam. The side walls of the rotating rod 18 close to the insulation plate 16 are installed in a circular array with several guide plates 17 for stirring the foam and guiding the foam to the opening of the conical fixing plate 15. The upper end of the guide plate 17 is in close contact with the lower end of the insulation plate 16.

[0028] During use, the motor 10, the first electric heating plate 14, and the electric heating column 6 are started. The output end of the motor 10 drives the rotating rod 18 to rotate, and the rotating rod 18 drives the second stirring rod 19 to stir and ferment the material. The fermented foam overflows to the upper end of the first electric heating plate 14 through the opening of the conical fixed plate 15. Since the surface of the first electric heating plate 14 is dry and rough, the foam will burst quickly. When the foam accumulates, the foam will contact the electric heating column 6. Since the surface of the electric heating column 6 is dry and rough, the foam will burst quickly.

[0029] At the same time, the guide plate 17 will stir the newly accumulated foam to break it. As the foam becomes more and more and the guide plate 17 becomes wet, the guide plate 17 will guide the foam to accelerate the foam to overflow the opening of the conical fixing plate 15.

[0030] The condensing mechanism includes a conical cooling plate 7, which is mounted on the inner wall of the tank body 1 above the electric heating column 6. The top center position of the conical cooling plate 7 is rotatably connected to the side wall of the rotating rod 18. The upper end of the conical cooling plate 7 is provided with a refrigeration component 9 for reducing the temperature of the conical cooling plate 7. A collecting frame 11 for collecting condensed water is installed on the inner wall of the tank body 1 at the lower end of the conical cooling plate 7. A scraper 8 for scraping off water droplets at the lower end of the diverter conical cooling plate 7 is installed on the side wall of the rotating rod 18 at the lower end of the conical cooling plate 7. The upper end of the scraper 8 is tightly attached to the lower end of the conical cooling plate 7, and the lower end of the scraper 8 extends above the collecting frame 11. An air supply pipe 12 is installed on the side wall of the tank body 1 between the collecting frame 11 and the electric heating column 6. The output end of the air supply pipe 12 passes through the tank body 1 and is provided with a pressure relief valve 13. A processing component for treating condensed water is provided on the side wall of the tank body 1.

[0031] The processing assembly includes a fixed frame 20 and an electrically controlled three-way valve 25. The fixed frame 20 is installed on the side wall of the tank body 1. An S-shaped heat pipe 23 for heating the condensed water is vertically installed inside the fixed frame 20. A second electric heating plate 21 for heating the S-shaped heat pipe 23 is installed on the inner wall of the fixed frame 20. The S-shaped heat pipe 23 is closely attached to the second electric heating plate 21. The input end of the S-shaped heat pipe 23 passes through the fixed frame 20 and is installed with a liquid inlet pipe 22. One end of the liquid pipe 22 away from the fixed frame 20 passes through the side wall of the tank body 1 and is arranged at the bottom of the collecting frame 11. The three joints of the electric-controlled three-way valve 25 are respectively installed with a connecting pipe 24, a second liquid outlet pipe 27 and a first liquid outlet pipe 26. The end of the connecting pipe 24 away from the electric-controlled three-way valve 25 passes through the fixed frame 20 and is installed at the output end of the S-shaped heat conduction pipe 23. The end of the first liquid outlet pipe 26 away from the electric-controlled three-way valve 25 passes through the side wall of the tank body 1 between the guide plate 17 and the feed pipe 4 and is arranged inside the tank body 1.

[0032] When in use, the refrigeration component 9 is started, and the refrigeration component 9 cools and cools the conical cooling plate 7. After the foam is defoamed, the liquid after the foam bursts will be evaporated due to the high temperature of the electric heating column 6 and the first electric heating plate 14. The water vapor will condense into water droplets at the lower end of the conical cooling plate 7 when it encounters the conical cooling plate 7, and then flow along the lower end of the conical cooling plate 7 to the inside of the collecting frame 11. The condensed water inside the collecting frame 11 flows into the inside of the S-shaped heat pipe 23 through the liquid inlet pipe 22.

[0033] At the same time, the second electric heating plate 21 is started to heat the S-shaped heat pipe 23, so that the S-shaped heat pipe 23 heats the condensed water inside. The heated condensed water is transported to the inside of the electric three-way valve 25 through the connecting pipe 24. If the humidity inside the tank body 1 is appropriate, the condensed water is discharged through the second liquid outlet pipe 27. If the humidity inside the tank body 1 is low and water needs to be added, the condensed water is transported to the inside of the tank body 1 through the first liquid outlet pipe 26.

[0034] The working principle of a fermentation tank with built-in defoaming and gas-liquid separation device:

[0035] During use, the motor 10, the first electric heating plate 14, and the electric heating column 6 are started. The output end of the motor 10 drives the rotating rod 18 to rotate, and the rotating rod 18 drives the second stirring rod 19 to stir and ferment the material. The fermented foam overflows to the upper end of the first electric heating plate 14 through the opening of the conical fixed plate 15. Since the surface of the first electric heating plate 14 is dry and rough, the foam will burst quickly. When the foam accumulates, the foam will contact the electric heating column 6. Since the surface of the electric heating column 6 is dry and rough, the foam will burst quickly.

[0036] At the same time, the guide plate 17 will stir the newly accumulated foam to break it. As the foam becomes more and more and the guide plate 17 becomes wet, the guide plate 17 will guide the foam to accelerate the foam to overflow the opening of the conical fixing plate 15.

[0037] Start the refrigeration component 9, which cools and cools the conical cooling plate 7. After the foam is defoamed, the liquid after the foam bursts will be evaporated due to the high temperature of the electric heating column 6 and the first electric heating plate 14. The water vapor will condense into water droplets at the lower end of the conical cooling plate 7 when it encounters the conical cooling plate 7, and then flow along the lower end of the conical cooling plate 7 to the inside of the collecting frame 11. The condensed water inside the collecting frame 11 flows into the inside of the S-shaped heat pipe 23 through the liquid inlet pipe 22.

[0038] At the same time, the second electric heating plate 21 is started to heat the S-shaped heat pipe 23, so that the S-shaped heat pipe 23 heats the condensed water inside. The heated condensed water is transported to the inside of the electric three-way valve 25 through the connecting pipe 24. If the humidity inside the tank body 1 is appropriate, the condensed water is discharged through the second liquid outlet pipe 27. If the humidity inside the tank body 1 is low and water needs to be added, the condensed water is transported to the inside of the tank body 1 through the first liquid outlet pipe 26.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
