[0001] The utility model relates to the technical field of biogas collection, in particular to a biogas collection cabin device. Background Art
[0002] Biogas is a combustible gas produced by microbial fermentation of organic matter under anaerobic conditions. It is mainly composed of methane and carbon dioxide, and may also contain small amounts of hydrogen, nitrogen, hydrogen sulfide and water vapor. Biogas is a combustible gas produced by the fermentation of various organic substances under suitable temperature and pH value and isolated from the air by microorganisms. Biogas is a secondary energy source and a renewable energy source. It is often used as household fuel, power generation and automobile fuel. Biogas collection refers to the process of capturing and storing biogas produced by anaerobic fermentation of organic waste for further use. An effective biogas collection system can not only improve the yield and quality of biogas, but also reduce environmental pollution and greenhouse gas emissions. In the prior art, the collection bins of multiple fermentation devices do not have an effective pressure balancing mechanism, which makes it difficult to balance the gas pressure inside different devices, resulting in excessive or low pressure inside some devices, affecting the stability and efficiency of biogas production, and even causing damage to the equipment.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.
[0007] Furthermore, the flange is provided with fixing holes, and the fixing holes are distributed in a circular array on the flange.
[0008] The beneficial effects of adopting the above further scheme are:
[0009] The design of the fixing holes distributed in a circular array allows the flange to be more evenly stressed when connected to the fermentation device. The evenly distributed fixing holes can keep the flange stable during installation, avoiding deformation or damage caused by excessive force in a single direction, thereby improving the stability and durability of the overall structure.
[0010] Furthermore, the one-way valve plate is rotatably mounted on the fixed plate via a rotating shaft, and torsion springs are provided at both ends of the rotating shaft.
[0011] The beneficial effects of adopting the above further scheme are:
[0012] The torsion spring design ensures that the valve plate can only be opened in one direction, thereby ensuring the one-way flow of gas, preventing gas backflow, and protecting the stable operation of the system. The torsion spring also provides an automatic reset function. When the gas pressure decreases or stops working, the torsion spring will automatically restore the valve plate to the closed position, ensuring that the valve can automatically close when there is no external pressure.
[0013] Furthermore, the ends of the air supply pipe and the exhaust pipe penetrate through the fixing plate and are inserted into the fermentation device.
[0014] The beneficial effects of adopting the above further scheme are:
[0015] The gas supply pipe and exhaust pipe are designed with a fixed plate, and the ends pass through the fixed plate and are inserted into the fermentation device. This design can effectively fix the position of the pipeline to prevent the pipeline from shifting or loosening due to vibration or external force during operation. Stable fixation and support can reduce stress concentration at the pipeline connection and extend the service life of the pipeline and equipment.
[0016] Furthermore, the ends of the buffer air inlet pipe and the buffer air outlet pipe are located above the one-way valve plate.
[0017] The beneficial effects of adopting the above further scheme are:
[0018] Designing the ends of the buffer inlet pipe and buffer outlet pipe above the one-way valve plate helps optimize the gas flow path. This layout ensures clear and separate directions of inlet and outlet, and clear stratification of the inlet and outlet pipes. Operators can more effectively monitor the flow status and changes of the gas and adjust system parameters in time to achieve the best biogas collection effect and operating efficiency.
[0019] Furthermore, a fixing seat is installed in the groove, and the air supply pipe and the exhaust pipe are fixed with the assistance of the fixing seat.
[0020] The beneficial effects of adopting the above further scheme are:
[0021] By installing the fixing seat in the groove, the gas supply pipe and the exhaust pipe are effectively fixed. This design can prevent the pipeline from moving or loosening due to vibration or external force during operation, ensure the stability and safety of the pipeline system, and reduce the risk of equipment damage or operation accidents caused by loose pipelines.
[0022] The beneficial effects of the utility model are:
[0023] The collection bins of multiple fermentation devices are connected in series by using a buffer air inlet pipe and a buffer air outlet pipe. Each collection bin is provided with a one-way valve plate and a partition plate, so that under a certain pressure, the one-way valve plate can be opened to allow high-pressure gas to flow to other collection bins in series. The purpose of this is to balance the gas pressure inside different fermentation devices to prevent a device from being damaged or dangerous due to excessive internal pressure.
[0024] A one-way valve plate is rotatably mounted on the fixed plate. The one-way valve plate is designed with a rotating shaft and a torsion spring to limit the one-way valve plate to open in one direction only. This design ensures that the gas can flow out smoothly when exhaust is required, while preventing the backflow of gas, improving the safety and reliability of the system. A partition plate is also provided on the fixed plate to divide the interior of the collection bin into two parts. The buffer inlet pipe and the gas delivery pipe are located on one side, and the exhaust pipe and the buffer outlet pipe are located on the other side. This partition design helps to manage the direction and path of gas flow, thereby optimizing the efficiency of gas collection and delivery.

[0036] Embodiment 1
[0037] A biogas collection chamber device includes a flange 1, a collection chamber 3, a groove 6 and a fixing plate 9. The bottom end of the collection chamber 3 is provided with a flange 1, and fixing holes 2 are provided through the flange 1. The fixing holes 2 are distributed in a circular array on the flange 1. The design of the fixing holes 2 distributed in the circular array enables the flange 1 to be more evenly stressed when connected to a fermentation device. The evenly distributed fixing holes 2 can keep the flange 1 stable during the installation process, avoid deformation or damage caused by excessive force in a single direction, thereby improving the stability and durability of the overall structure. The collection chamber 3 is installed on the fermentation device through the flange 1, and a groove 6 is provided on the collection chamber 3. A fixing seat 13 is installed in the groove 6. The gas pipe 5 and the exhaust pipe 7 are assisted by the fixing seat 13. Biogas is provided to the outside through the gas pipe 5. When the internal air pressure of the fermentation device is too high, it can also be exhausted through the exhaust pipe 7. By installing the fixing seat 13 in the groove 6, the gas pipe 5 and the exhaust pipe 7 are effectively assisted and fixed. This design can prevent the pipeline from moving or loosening due to vibration or external force during operation, ensure the stability and safety of the pipeline system, and reduce the risk of equipment damage or operation accidents caused by loose pipelines. The collection bin 3 is penetrated by a buffer air inlet pipe 4, an air delivery pipe 5, an exhaust pipe 7 and a buffer air outlet pipe 8. The collection bins 3 of multiple fermentation devices are connected in series through the buffer air inlet pipe 4 and the buffer air outlet pipe 8. When the internal pressure of the fermentation device is too high, the air pressure will push the one-way valve plate 10 to open, so that the high-pressure gas flows to the remaining collection bins 3 in series, and enters the remaining fermentation devices through the collection bin 3. A fixing plate 9 is provided inside the collection bin 3. The ends of the air delivery pipe 5 and the exhaust pipe 7 penetrate the fixing plate 9 and are inserted into the fermentation device. The ends of the air delivery pipe 5 and the exhaust pipe 7 penetrate the fixing plate 9 and are inserted into the fermentation device through the design of the fixing plate 9. This design can effectively fix the position of the pipeline and prevent the pipeline from shifting or loosening due to vibration or external force during operation. Stable fixation and support can reduce stress concentration at the pipe joints and extend the service life of pipes and equipment. A one-way valve plate 10 is rotatably mounted on the fixed plate 9. The one-way valve plate 10 is rotatably mounted on the fixed plate 9 via a rotating shaft 11, and torsion springs are provided at both ends of the rotating shaft 11. The one-way valve plate 10 can only be opened in one direction due to the torsion spring restriction. The design of the torsion spring ensures that the valve plate can only be opened in one direction, thereby ensuring the one-way flow of gas, preventing gas backflow, and protecting the stable operation of the system. The torsion spring also provides an automatic reset function. When the air pressure decreases or stops working, the torsion spring will automatically restore the valve plate to the closed position to ensure that the valve can automatically close when there is no external pressure. The ends of the buffer inlet pipe 4 and the buffer outlet pipe 8 are located above the one-way valve plate 10. Designing the ends of the buffer inlet pipe 4 and the buffer outlet pipe 8 above the one-way valve plate 10 helps to optimize the flow path of the gas.This layout ensures that the directions of air intake and air outlet are clear and separated, and the air intake pipe and the air outlet pipe are clearly layered. The operator can monitor the flow state and changes of the gas more effectively and adjust the system parameters in time to achieve the best biogas collection effect and operating efficiency. A partition plate 12 is provided on the fixed plate 9, and the interior of the collection bin 3 is divided into two parts by the partition plate 12, and a group of buffer air intake pipe 4 and air transmission pipe 5, and a group of exhaust pipe 7 and buffer air outlet pipe 8 are respectively located on both sides of the partition plate 12.
[0038] When a biogas collection chamber device according to Example 1 is used:
[0039] The collection bins 3 of multiple fermentation devices are connected in series by using a buffer air inlet pipe 4 and a buffer air outlet pipe 8. Each collection bin 3 is provided with a one-way valve plate 10 and a partition plate 12, so that under a certain pressure, the one-way valve plate 10 can be opened to allow high-pressure gas to flow to other collection bins 3 connected in series. The purpose of this is to balance the gas pressure inside different fermentation devices and prevent a device from being damaged or dangerous due to excessive internal pressure.
[0040] A one-way valve plate 10 is rotatably mounted on the fixed plate 9. The one-way valve plate 10 is designed with a rotating shaft 11 and a torsion spring to limit the one-way valve plate 10 to open in one direction only. This design ensures that the gas can flow out smoothly when exhaust is required, while preventing the backflow of gas, thereby improving the safety and reliability of the system. A partition plate 12 is provided on the fixed plate 9 to divide the interior of the collection bin 3 into two parts. The buffer inlet pipe 4 and the gas delivery pipe 5 are located on one side, and the exhaust pipe 7 and the buffer outlet pipe 8 are located on the other side. This partition design helps to manage the direction and path of gas flow, thereby optimizing the gas collection and delivery efficiency.
