[0026] An embodiment of the present utility model provides a pressure relief device for beer fermentation, including a pressure relief cylinder 1. Exemplarily, as Figure 1 、 Figure 3 and Figure 5 shown, two sets of mounting blocks 2 are symmetrically and slidably fitted to both ends of the pressure relief cylinder 1. Two sets of fixing plates 3 are installed at both ends of each set of mounting blocks 2. One side wall of each set of fixing plates 3 is slidably fitted to the outer wall of the pressure relief cylinder 1. One set of screws 4 is provided at one end of each set of fixing plates 3 away from the pressure relief cylinder 1. The output ends of each set of screws 4 penetrate through the fixing plates 3 and are threadedly connected to the pressure relief cylinder 1. One set of moving grooves 5 is opened at the top of each set of mounting blocks 2. One set of moving blocks 6 is slidably disposed in each set of moving grooves 5. One set of screw rods 7 is rotatably connected to one end of each set of moving blocks 6 away from the pressure relief cylinder 1. One set of threaded holes 8 is opened on one side wall of each set of mounting blocks 2 away from the pressure relief cylinder 1. One end of each set of screw rods 7 away from the moving blocks 6 penetrates through the threaded holes 8 and is provided with one set of fixing blocks 9. Each set of fixing blocks 9 is located at one end of the mounting block 2 away from the pressure relief cylinder 1. One set of connecting plates 10 is provided above each set of mounting blocks 2. The bottom of each set of connecting plates 10 is installed on the top of one set of moving blocks 6. One set of connecting blocks 11 is installed on one side wall of each set of connecting plates 10 close to the pressure relief cylinder 1. One set of arc-shaped clamping plates 12 is installed at one end of each set of connecting blocks 11 away from the connecting plates 10. One set of sealing gaskets 21 is installed on one side wall of each set of arc-shaped clamping plates 12 away from the connecting blocks 11. A cavity 20 is opened at the center of the top of the pressure relief cylinder 1.

[0027] Exemplarily, as Figure 2 and Figure 4As shown in the figure, a number of groups of air outlet holes 13 are arranged in a circular array on the outer wall of the pressure relief cylinder 1. A motor 14 is arranged directly below the pressure relief cylinder 1. The output end of each motor 14 penetrates through the pressure relief cylinder 1 and is drivingly connected to a rotating rod 15. The rotating rod 15 is located in the cavity 20. A set of threaded columns 16 are installed on the output end of each rotating rod 15. The outer wall of each threaded column 16 is slidably attached to the inner wall of the pressure relief cylinder 1. An installation groove 17 is opened at the center of the side wall of the threaded column 16 away from the rotating rod 15. A spring 18 is arranged in the installation groove 17. A top block 19 is arranged directly above the installation groove 17. One end of the spring 18 is installed on the inner wall of the threaded column 16. The other end of the spring 18 penetrates through the installation groove 17 and is installed on the top block 19. A pressure sensor is arranged at the contact position of the spring 18 and the top block 19.

[0028] Working principle: By placing one end of the pressure relief pipe into the cavity 20, when the fixing block 9 is rotated to drive the screw rod 7 to rotate, the moving block 6 is driven to move in the moving groove 5. While the moving block 6 drives the connecting plate 10 to move, the connecting block 11 is driven to move. The connecting block 11 drives the arc-shaped clamping plate 12 and the sealing gasket 21 to move, clamping the pressure relief pipe, so that the device is fixed at one end of the pressure relief pipe. Rotating the fixing block 9 in the reverse direction to drive the arc-shaped clamping plate 12 and the sealing gasket 21 away from the pressure relief pipe can make the device withdraw from the end of the pressure relief pipe, and the device can be installed and disassembled. After the screws 4 are rotated in turn to withdraw the pressure relief cylinder 1 and the fixing plate 3, the fixing plate 3 and the installation block 2 are separated from the pressure relief cylinder 1, which is convenient for the staff to carry out maintenance and cleaning work in the cavity 20, and is also convenient for replacing the installation block 2 and the fixing plate 3. When the motor 14 drives the rotating rod 15, the threaded column 16 is driven to rotate, and it is screwed towards the end of the threaded column 16 away from the motor 14 to adjust the tightness of the spring 18 and preset the pressure value. The pressure gauge detects the pressure in the fermentation tank and transmits the signal to the control system. The gas generated in the fermentation tank enters the pressure relief cylinder 1 through the pressure relief pipe. When the pressure in the fermentation tank reaches the preset value, the top block 19 is pushed towards the threaded column 16, and the spring 18 is compressed. The pressure sensor arranged at the contact position of the spring 18 and the top block 19 transmits the pressure signal to the control system. When the motor 14 drives the rotating rod 15 to rotate, the threaded column 16 is driven to rotate and move closer to the motor 14 to reduce the deformation amount of the spring 18.

[0029] By placing one end of the pressure relief pipe into the cavity 20, when the fixing block 9 is rotated to drive the screw rod 7 to rotate, the moving block 6 is driven to move. While the moving block 6 drives the connecting plate 10 to move, the connecting block 11 is driven to move. The connecting block 11 drives the arc-shaped clamping plate 12 and the sealing gasket 21 to move, clamping the pressure relief pipe, so that the device is fixed at one end of the pressure relief pipe. Rotating the fixing block 9 in the reverse direction to drive the arc-shaped clamping plate 12 and the sealing gasket 21 away from the pressure relief pipe can make the device withdraw from the end of the pressure relief pipe, and the device can be installed and disassembled. It can be used on multiple groups of pressure relief pipes, reducing the limitations, improving the practicability and convenience at the same time.

[0030] After the rotating screw 4 is successively withdrawn from the pressure relief cylinder 1 and the fixing plate 3, the fixing plate 3 and the mounting block 2 are separated from the pressure relief cylinder 1, which facilitates the maintenance and cleaning work inside the cavity 20 by the staff. At the same time, it is also convenient to replace the mounting block 2 and the fixing plate 3, improving the service life of the equipment.

[0031] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
