Description

Technical Field

[0001] The utility model belongs to the technical field of anaerobic fermentation, in particular to a double-membrane top gas cabinet type anaerobic fermentation tank operation detection device. Background Art

[0002] Double-membrane top gas cabinet anaerobic fermentation tanks can efficiently collect and store biogas. Their retractable design automatically adjusts the volume according to the amount of biogas produced, maintaining a stable pressure inside the tank. This also reduces the need for separate biogas storage facilities, saving space. The double-layer membrane structure provides excellent sealing performance, helping to maintain an anaerobic environment and improve fermentation efficiency. The inner membrane is used to store gas, while the outer membrane acts as a pressure regulating layer. The pressure of the gas cabinet is adjusted by controlling the device to fill or exhaust air into the outer membrane, thereby improving system safety. However, its disadvantages are relatively high maintenance requirements, requiring regular inspection of the membrane material's integrity and airtightness to ensure its normal working condition. Operation and maintenance are also relatively complex.

[0003] For this type of fermentation tank, it is very important to understand the status of the inner membrane to prevent the inner membrane from bursting due to excessive gas or excessive gas consumption due to insufficient gas, which may lead to negative pressure. However, due to the double-membrane top design, the gas production in the anaerobic tank cannot be directly observed from the outside. The membrane top level meter often has uneven pressure on the inner membrane, which causes fluctuations and inaccurate measurements. Manual personnel need to climb to the top of the tank through the tank ladder and observe and judge through the window, which requires high labor costs. Utility Model Content

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model discloses a double-membrane top gas cabinet type anaerobic fermentation tank operation detection device, the double-membrane top gas cabinet type anaerobic fermentation tank 1 includes a tank body 101, an inner membrane 102 and an outer membrane 103, the inner membrane 102 is located inside the tank body 101, the outer membrane 103 is partially embedded in the tank body 101, and the other part of the outer membrane 103 is located outside the tank body 101, and the operation detection device is installed on the top of the inner side of the outer membrane 103, and the operation detection device includes a first detection device 2, the first detection device 2 includes a support frame 201 and a hanger 204, the support frame 201 and the hanger 204 are respectively installed on the inner top of the outer membrane 103, and a plurality of detection holes 211 are opened on the hanger 204. A trigger is installed in the measuring hole 211, and a sliding member 202 is slidably connected to the support frame 201. The sides of the sliding member 202 are respectively fixed with a fixing member 205 and several fixing frames 203. The fixing member 205 is fixed with a first fixed cylinder 206 and a second fixed cylinder 208. The second fixed cylinder 208 is sleeved with a special-shaped body 209. The second fixed cylinder 208 is rotatably connected to the special-shaped body 209. The first fixed cylinder 206 is fixed with a spring 207. The end of the spring 207 away from the first fixed cylinder 206 is fixed with a third fixed cylinder 210. The third fixed cylinder 210 is fixed to the second fixed cylinder 208, and the special-shaped body 209 is adapted to the measuring hole 211.

[0022] The first detection device 2 utilizes the force generated by the bulging of the inner membrane 102, and through the coordinated action of the mechanical structure (including the support frame 201, the hanger 204, the sliding member 202, the fixing member 205, the fixing frame 203, the shaped body 209, etc.), indirectly monitors the internal state of the fermenter. The first detection device 2 has a stable structure and can effectively monitor the bulging state of the inner membrane 102 of the fermenter, thereby determining whether the fermenter is operating normally. This improves detection efficiency, enhances operational safety, and provides reliable protection for the anaerobic fermentation process.

[0023] Specifically, the inner membrane 102 bulges to move the fixing frame 203 and the sliding member 202 upward, driving the shaped body 209 upward. The shaped body 209 rotates around the second fixing cylinder 208 under the action of gravity and the spring 207 to contact the detection hole 211.

[0024] Optionally, the operation detection device includes a second detection device 3 , which is installed on the top inner side of the outer membrane 103 .

[0025] The installation position of the second detection device 3 is combined with the internal top of the outer membrane 103, which is convenient for monitoring the internal and external environments of the fermentation tank at the same time, improving the comprehensiveness and accuracy of the monitoring, and at the same time monitoring the working status of the first monitoring device, making the entire detection device more complete and able to more comprehensively reflect the operating status of the fermentation tank.

[0026] Preferably, the second detection device 3 includes a camera.

[0027] The camera can capture image information inside the fermentation tank in real time, providing operators with intuitive and clear visual feedback; it improves the intuitiveness of monitoring, facilitates the timely detection and handling of abnormal situations, and enhances the safety and reliability of operation.

[0028] Furthermore, the second detection device 3 also includes a temperature sensor.

[0029] The temperature condition inside the fermentation tank can be monitored through the temperature sensor; temperature is one of the key parameters in the anaerobic fermentation process, and its stability directly affects the fermentation effect; the addition of the temperature sensor enables the operator to grasp the temperature changes in the fermentation tank in real time, adjust the process parameters in time, and ensure the smooth progress of the fermentation process.

[0032] Optionally, the triggering member is a pressure sensor.

[0033] The pressure sensor can directly sense the pressure changes generated when the irregular body 209 contacts the detection hole 211, allowing the device to more sensitively respond to changes in the internal state of the fermenter, improving the accuracy and reliability of monitoring. The pressure sensor also has the advantages of a simple structure and is easy to install and maintain, reducing the cost of the device. Furthermore, each pressure sensor is connected to the alarm network. Based on the different pressure sensors in each location, the alarm lights and sounds are different. For example, from bottom to top on the hanger 204 are the first, second, and third pressure sensors; the alarm lights are green, yellow, and red, respectively; and the alarm sounds are the first, second, and third alarm sounds, respectively.

[0034] Optionally, a rubber sheet is installed at the bottom end of the fixing frame 203 .

[0035] In order to increase the contact degree between the fixing frame 203 and the inner membrane 102, a rubber sheet is installed at the bottom end of the fixing frame 203; at the same time, the rubber sheet also has a certain buffering effect, which can reduce the impact of the impact force generated when the inner membrane 102 bulges on the device; thereby improving the durability of the device and enhancing its operational stability and safety.
