Description

Technical Field

[0001] This utility model relates to the field of fermentation tanks, and in particular to a pressure balancing venting device for beer fermentation tanks. Background Technology

[0002] Beer fermentation tanks are the core equipment used in the beer brewing process to realize the fermentation of beer yeast. Their main function is to provide a suitable environment for yeast to break down fermentable sugars in wort, producing alcohol, carbon dioxide and various flavor substances, and ultimately converting wort into beer mash.

[0003] Publication number CN216786080U discloses a fermentation tank for fermenting wine. As the pressure inside the fermentation tank increases, gas passes through the vent pipe and pushes a sealing block upwards. When the sealing block reaches the top of the vent, the gas in the fermentation tank can be discharged through the vent. When the gas in the fermentation tank reaches equilibrium, the sealing block moves downwards due to gravity, resealing the vent. This eliminates the need for manual, periodic venting, making venting during fermentation simple and convenient, and meeting existing venting needs. However, this fermentation tank is not convenient for adjusting to different pressure requirements during fermentation, exhibiting relatively low flexibility and failing to adapt to diverse needs.

[0004] Therefore, it is necessary to provide a pressure balancing venting device for beer fermentation tanks to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a pressure balancing venting device for beer fermentation tanks, which solves the problem that some beer fermentation tanks are not easy to adjust according to different pressure requirements during fermentation.

[0006] To solve the above-mentioned technical problems, this utility model provides a pressure balancing exhaust device for a beer fermentation tank, comprising: a tank body and a pressure balancing mechanism;

[0007] The pressure balancing mechanism includes an exhaust pipe connected to the top of the tank. A bracket is fixed to the right side of the top of the tank. A threaded guide rod is fixed to the bottom of the bracket. A sealing block is slidably connected to the surface of the threaded guide rod and inside the exhaust pipe. A spring is sleeved on the surface of the threaded guide rod and on top of the sealing block. An adjusting screw is provided on the surface of the threaded guide rod and on top of the spring.

[0008] Preferably, the surface of the exhaust pipe is provided with a plurality of small ventilation holes, and the inner wall of the exhaust pipe is provided with a support ring for use in conjunction with the sealing block to limit the position of the sealing block. The support ring is located at the bottom of the ventilation holes.

[0009] Preferably, a stirring mechanism is vertically rotatably connected inside the tank. The stirring mechanism includes a stirring shaft vertically rotatably connected inside the tank. Multiple stirring racks are arranged on the surface of the stirring shaft and inside the tank. A drive motor for driving the stirring shaft to rotate is arranged on the top of the tank.

[0010] Preferably, a mounting sleeve is threadedly fixed to the circumferential side of the stirring shaft and inside the tank. Four connecting rods are arranged in a circular array on the surface of the mounting sleeve, and a cleaning plate is fixed to one end of each of the four connecting rods.

[0011] Preferably, the bottom of the tank is fixedly provided with four support legs, and the inner side of the bottom of each of the four support legs is threaded with a support seat. The four support legs are connected to each other by a reinforcing rod.

[0012] Preferably, a sampling tube is connected to the left side of the can, and a valve is provided on the surface of the sampling tube. The sampling tube is used to sample and test the beer inside the can.

[0013] Preferably, a flange is fixed to the bottom of the tank, and the flange is used to connect to the discharge equipment.

[0014] Compared with related technologies, the pressure balancing exhaust device for beer fermentation tanks provided by this utility model has the following beneficial effects:

[0015] This invention provides a pressure balancing venting device for a beer fermentation tank. By turning the adjusting screw downwards, the spring is compressed downwards, increasing its expansion force. As the spring's expansion force increases, only when the pressure inside the tank is higher will the sealing block be lifted. The position of the adjusting screw can be freely adjusted according to the user's needs. When the tank is used for high-pressure reactions, the spring pressure can be increased to raise the venting threshold and meet the requirements of high-pressure environments. When handling low-pressure material reactions, the spring pressure can be decreased to ensure venting even with slight overpressure, avoiding pressure fluctuations from affecting material stability. This effectively improves the flexibility of the device during use and can adapt to diverse user needs. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of a preferred embodiment of a pressure balancing exhaust device for a beer fermentation tank provided by this utility model; Figure 2 A schematic diagram of the stirring mechanism provided by this utility model; Figure 3 A schematic diagram of the pressure balancing mechanism provided by this utility model; Figure 4 for Figure 3 The structural schematic diagram of the cross-sectional view of the exhaust pipe shown illustrates a pressure balancing exhaust device for a beer fermentation tank, comprising: a tank body 1 and a pressure balancing mechanism 2;

[0023] The pressure balancing mechanism 2 includes an exhaust pipe 21 connected to the top of the tank body 1. A bracket 22 is fixedly provided on the right side of the top of the tank body 1. A threaded guide rod 23 is fixedly provided at the bottom of the bracket 22. A sealing block 24 is slidably connected to the surface of the threaded guide rod 23 and inside the exhaust pipe 21. A spring 25 is sleeved on the surface of the threaded guide rod 23 and on top of the sealing block 24. An adjusting screw block 26 is provided on the surface of the threaded guide rod 23 and on top of the spring 25.

[0024] When the pressure inside the tank 1 reaches a certain value, it will push the sealing block 24 upward, causing the sealing block 24 to slide upward on the surface of the threaded guide rod 23. When the height of the sealing block 24 moving upward exceeds the vent hole, the gas will be discharged from the vent hole. After a certain amount of gas is discharged, the pressure inside the tank 1 decreases. Through the expansion force of the spring 25, the sealing block 24 slides downward on the surface of the threaded guide rod 23, resealing the exhaust pipe 21.

[0025] Furthermore, by turning the adjusting screw 26 downward, the spring 25 is compressed downward, increasing the expansion force of the spring 25. When the expansion force of the spring 25 increases, only when the pressure value inside the tank 1 is greater will the sealing block 24 be lifted up. Thus, the position of the adjusting screw 26 can be freely adjusted according to the user's needs.

[0026] The surface of the exhaust pipe 21 is provided with a plurality of small ventilation holes, and the inner wall of the exhaust pipe 21 is provided with a support ring that works with the sealing block 24 to limit the position of the sealing block 24. The support ring is located at the bottom of the ventilation holes.

[0027] The tank 1 is vertically rotatably connected to a stirring mechanism 3. The stirring mechanism 3 includes a stirring shaft 31 vertically rotatably connected to the inside of the tank 1. Multiple stirring racks 32 are arranged on the surface of the stirring shaft 31 and inside the tank 1. A drive motor 33 for driving the stirring shaft 31 to rotate is arranged on the top of the tank 1.

[0028] Start the drive motor 33. The drive motor 33 rotates and drives the stirring shaft 31 to rotate. The rotation of the stirring shaft 31 in turn drives multiple sets of stirring racks 32 to rotate, mixing the fermentation material in the tank 1.

[0029] The circumferential side of the stirring shaft 31 and inside the tank 1 is fixedly fitted with an installation sleeve 4 by threads. The surface of the installation sleeve 4 is arranged in a ring array of four connecting rods 5. A cleaning plate 6 is fixedly fitted at one end of each of the four connecting rods 5.

[0030] When the stirring shaft 31 rotates, it will simultaneously drive the connecting rod 5 and the cleaning plate 6 to rotate through the mounting sleeve 4. The rotation of the cleaning plate 6 will clean the foam or water droplets splashed on the inner wall of the tank 1 during the mixing of fermentation materials.

[0031] The bottom of the tank body 1 is fixed with four support legs 7, and the inner side of the bottom of each of the four support legs 7 is threaded with a support seat 8. The four support legs 7 are connected to each other by a reinforcing rod.

[0032] A sampling tube 9 is connected to the left side of the tank 1. A valve is provided on the surface of the sampling tube 9. The sampling tube 9 is used to sample and test the beer inside the tank 1.

[0033] A flange 10 is fixed at the bottom of the tank body 1, and the flange 10 is used to connect to the discharge equipment.

[0034] The working principle of the pressure balancing venting device for a beer fermentation tank provided by this utility model is as follows:

[0035] When in use, start the drive motor 33. The drive motor 33 rotates and drives the stirring shaft 31 to rotate. The rotation of the stirring shaft 31 in turn drives multiple sets of stirring racks 32 to rotate, mixing the fermented material in the tank 1. When the stirring shaft 31 rotates, it will simultaneously drive the connecting rod 5 and the cleaning plate 6 to rotate through the mounting sleeve 4. The rotation of the cleaning plate 6 cleans the foam or water droplets splashed on the inner wall of the tank 1 when the fermented material is mixed.

[0036] When the pressure inside the tank 1 reaches a certain value, it will push the sealing block 24 upward, causing the sealing block 24 to slide upward on the surface of the threaded guide rod 23. When the height of the sealing block 24 moving upward exceeds the vent hole, the gas will be discharged from the vent hole. After a certain amount of gas is discharged, the pressure inside the tank 1 decreases. Through the expansion force of the spring 25, the sealing block 24 slides downward on the surface of the threaded guide rod 23, resealing the exhaust pipe 21. By turning the adjusting screw 26 downward, the spring 25 is squeezed downward, increasing the expansion force of the spring 25. When the expansion force of the spring 25 increases, only when the pressure inside the tank 1 is greater will the sealing block 24 be pushed up.

[0037] Compared with related technologies, the pressure balancing exhaust device for beer fermentation tanks provided by this utility model has the following beneficial effects:

[0038] By turning the adjusting screw 26 downwards, the spring 25 is compressed downwards, increasing the expansion force of the spring 25. As the expansion force of the spring 25 increases, only when the pressure inside the tank 1 is higher will the sealing block 24 be lifted. Thus, the position of the adjusting screw 26 can be freely adjusted according to the user's needs. When the tank 1 is used for high-pressure reactions, the pressure of the spring 25 can be increased to raise the venting threshold and meet the requirements of the high-pressure environment. When processing low-pressure material reactions, the pressure of the spring 25 can be decreased to ensure that venting occurs even with slight overpressure, avoiding pressure fluctuations from affecting the stability of the material. This effectively improves the flexibility of the device during use and can adapt to the diverse needs of users.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
