[0024] Example 1

[0025] like Figures 1 to 5 As shown, this utility model relates to a pressure detection device for a fermenter, comprising:

[0026] The tank 1 is cylindrical, with a support at the bottom for support. A motor 15 is mounted on the top of the tank 1, and the output shaft of the motor 15 is coaxially inserted into the interior of the tank 1. The output shaft of the motor 15 is coaxially connected to a stirring blade 16, which drives the stirring blade 16 to rotate and stir the material in the tank 1. A discharge pipe is connected to the bottom of the tank 1 for discharging the material after the microbial fermentation is completed. A valve is installed on the discharge pipe to control the discharge.

[0027] A pressure relief assembly 2 for depressurizing the tank 1 is also provided on the side wall near the top of the tank 1. The pressure relief assembly 2 includes: a pressure relief box 3 fixedly installed on the side wall of the tank 1 near the top position. The side of the pressure relief box 3 near the tank 1 is arc-shaped and matches the tank 1. An air outlet pipe 13 is provided inside the pressure relief box 3. The air inlet end of the air outlet pipe 13 is connected to the tank 1, so that the gas in the tank 1 can be discharged through the air outlet pipe 13, thereby depressurizing the tank 1.

[0028] An airbag 4 is installed on the inner wall of the air inlet end of the air outlet pipe 13, and the air outlet pipe 13 is arranged in a horizontal direction; the airbag 4 is arranged horizontally parallel inside the air outlet pipe 13, and the airbag 4 can extend and retract in a horizontal direction.

[0029] The telescopic end of the airbag 4 is equipped with a sealing block 6. The sealing block 6 is frustoconical and has an inclined surface that matches the wedge block 5. The sealing block 6 is made of rubber material, and several air vents are circumferentially formed on the sealing block 6. The opening direction of the air vents is towards the wedge block 5 (i.e. towards the wedge block 5). Figure 3 (on the left side of the middle), used for exhaust, the diameter of the exhaust hole is smaller than the inner diameter of the exhaust pipe 13.

[0030] A wedge-shaped block 5 is installed on the inner wall of the vent pipe 13. The wedge-shaped block 5 is arranged coaxially along the annular axis on the inner wall of the vent pipe 13. The wedge-shaped block 5 and the sealing block 6 cooperate to form a one-way gas-blocking structure. Specifically, when the vent pipe 13 is ventilated, high-pressure gas passes through the vent pipe 13 into the air bladder 4 and is discharged from the vent hole of the sealing block 6, effectively avoiding serious safety accidents such as explosions that may be caused by excessive pressure inside the tank 1, and providing reliable safety for the microbial fermentation process. When the air intake speed exceeds the exhaust speed, the air bladder 4 expands and slides laterally; otherwise, the air bladder 4 does not expand. When the pressure at the outlet end of the vent pipe 13 is greater than the pressure at the inlet end of the vent pipe 13, the air pressure causes the sealing block 6 to press against the wedge-shaped block 5, thereby preventing gas from flowing from the outlet end of the vent pipe 13 into the tank 1.

[0031] Preferably, a transmission rod 7 is installed at the end of the sealing block 6 away from the airbag 4, a rack 8 is installed at the bottom of the transmission rod 7, the rack 8 is meshed with a gear 9, and the gear 9 is coaxially connected to a pointer 14.

[0032] An indicator plate 10 is installed on the side wall of the pressure relief box 3. The indicator plate 10 is disc-shaped and has scales and indication text (such as: slight leakage, moderate leakage, severe leakage, etc.) on its outer surface. Workers can take corresponding measures according to the indication text.

[0033] The indicator disk 10 has a through hole in the middle, and a circular rod is connected inside the through hole; the indicator disk 10 is coaxially connected to the pointer 14; the top of the pointer 14 is located outside the indicator disk 10, and the bottom of the pointer 14 is connected to the gear 9 through the circular rod.

[0034] When the airbag 4 slides laterally, it causes the sealing block 6 to slide laterally, which in turn causes the transmission rod 7 to slide laterally, thereby causing the rack 8 to drive the gear 9 to rotate. When the gear 9 rotates, it drives the pointer 14 to rotate, so that the staff can take corresponding measures according to the text indicated by the pointer 14 when it rotates. The staff can intuitively understand the approximate pressure status inside the tank 1 without the need for complicated testing equipment, making the operation more convenient and efficient.

[0035] Preferably, an L-shaped rod 12 is installed on the top of the transmission rod 7; a micro switch 11 is also installed on the inner wall of the pressure relief box 3. The drive rod of the micro switch 11 is located on the movement path of the L-shaped rod 12. When the airbag 4 slides laterally, it also drives the L-shaped rod 12 to squeeze the micro switch 11. When the micro switch 11 is triggered, the system takes corresponding measures according to the preset instructions, such as turning on the alarm; turning off the motor 15; stopping the stirring blade 16 of the motor 15, etc., which can be set manually according to actual needs.

[0036] Example 2

[0037] The air inlet end of the air outlet pipe 13 is equipped with a solenoid valve, and the inside of the tank 1 is equipped with a pressure sensor. The solenoid valve and the pressure sensor are electrically connected to the PLC controller. When the pressure inside the tank 1 reaches a manually set threshold, the PLC controller controls the solenoid valve to open according to the manually preset instruction. At this time, the gas inside the tank 1 is introduced into the air outlet pipe 13.

[0038] The micro switch 11 is electrically connected to the PLC controller, which is also electrically connected to an alarm. When the micro switch 11 is triggered, the PLC controller controls the alarm to start according to a preset instruction, which can quickly notify the staff when the pressure in tank 1 is abnormal.

[0039] As can be seen from the above description, this utility model adopts a pressure relief component 2 installed on the side wall of the tank 1 to relieve pressure on the tank 1. The pressure relief component 2 includes: a pressure relief box 3 fixedly installed on the side wall of the tank 1 near the top; an air outlet pipe 13 disposed in the pressure relief box 3, the air inlet end of the air outlet pipe 13 being connected to the tank 1; an air bladder 4 installed on the inner wall of the air inlet end of the air outlet pipe 13, a sealing block 6 installed on the telescopic end of the air bladder 4, and a wedge block 5 installed on the inner wall of the air outlet pipe 13. The wedge block 5 and the sealing block 6 cooperate to form a one-way air-blocking structure, which achieves the technical effect of relieving pressure when the internal pressure of the tank 1 exceeds the threshold. This avoids the risk of increased pressure in the fermenter due to microbial respiration during microbial fermentation. If the pressure of the fermenter is not detected in time and pressure relief is not performed in time, dangerous technical problems may occur.
