Description

TECHNICAL FIELD

[0001] The utility model relates to a gas supply system technical field, especially a gas supply system. BACKGROUND

[0002] In the production process of lithium battery, power auxiliary room (also called auxiliary power system) plays a vital role. The main function of power auxiliary room is to ensure the stability of various environmental parameters in the workshop, including temperature, humidity, cleanliness and stable supply of gas. Because lithium battery production needs to use two kinds of gases with high purity, nitrogen and compressed air, nitrogen is often used for oxidation prevention, cleaning and environmental protection in the battery manufacturing process, while compressed air is used to drive mechanical equipment and clean the workshop. Therefore, ensuring the stable supply of these two kinds of gases has become an indispensable part of the lithium battery production process.

[0003] The existing gas supply system generally supplies gas through independent pipeline systems of nitrogen and compressed air. Nitrogen and compressed air are sent into the workshop through independent equipment and pipelines, and are distributed to different workstations in the workshop. Although this method can meet the production needs, because nitrogen and compressed air are supplied by independent pipelines, nitrogen and compressed air need to be configured with gas pipelines, which not only increases the production cost, but also requires a lot of research and investigation when laying pipelines and configuring equipment, greatly limiting the installation and debugging progress.

[0004] Therefore, how to reduce the construction cost of the existing gas supply system, improve its installation efficiency and speed up the debugging progress has become a technical problem to be solved. CONTENT OF THE UTILITY MODEL

[0005] The main purpose of the utility model is to provide a gas supply system, which aims to reduce the space occupation of the existing gas supply system and reduce its management difficulty on the basis of ensuring the quality and stability of gas supply.

[0006] In order to achieve the above purpose, the utility model provides a gas supply system, which comprises:

[0007] Nitrogen generator, used for generating nitrogen;

[0008] Air compressor, used for providing compressed air;

[0009] Nitrogen buffer tank, gas inlet connected to the nitrogen generator, used for buffering the nitrogen generated by the nitrogen generator, and the gas outlet of the nitrogen buffer tank is communicated with the workshop through at least one conveying pipe;

[0010] The compressed air buffer tank is connected to the air compressor through an air inlet for buffering the compressed air generated by the air compressor, and an air outlet of the compressed air buffer tank is connected to the conveying pipe through an air guide pipe;

[0011] The first ball valve is used for opening or closing the air outlet of the nitrogen buffer tank.

[0012] The second ball valve is used for opening or closing the air outlet of the compressed air buffer tank, so that only one kind of gas is allowed to pass through the conveying pipe at all times.

[0013] By using the nitrogen buffer tank and the compressed air buffer tank together, the gas supply can be quickly adjusted according to different needs in the workshop, and efficient supply of nitrogen and compressed air can be realized. The first ball valve and the second ball valve are arranged to ensure flexible switching between the supply of nitrogen and compressed air, and to avoid instability and mixing of the gas supply. The design of the two buffer tanks effectively combines the storage of nitrogen and compressed air, reduces the volume and complexity of the equipment, and improves the resource utilization rate. At the same time, on the basis of ensuring the quality and stability of the gas supply, the space occupied by the existing gas supply system is reduced, and the management difficulty is reduced.

[0014] In an embodiment of the present application, further comprising:

[0015] The nitrogen distributor has at least two air outlets for distributing the gas in the nitrogen buffer tank to different positions in the workshop, and the conveying pipe is connected to the air outlets of the nitrogen distributor.

[0016] The nitrogen distributor can distribute nitrogen to multiple areas according to the gas demand of different positions in the workshop, ensure the accuracy of gas supply, and avoid waste of resources. The design of multiple air outlets enables the system to adjust according to the gas demand of different areas in the workshop, meet the demand of different processes or equipment, and improve the adaptability of the system.

[0017] In an embodiment of the present application, a third ball valve is arranged on each air outlet of the nitrogen distributor for opening or closing each air outlet; wherein the opening and closing state of the third ball valve corresponding to the conveying pipe is always opposite to that of the second ball valve.

[0018] The reverse control of the third ball valve and the second ball valve ensures that nitrogen and compressed air cannot flow at the same time in the same conveying pipe, avoids the risk of cross-mixing of the gas, and thus guarantees the purity and quality of the gas.

[0019] In an embodiment of the present application, a pressure sensor is further arranged for detecting the air pressure in the nitrogen buffer tank and / or the air pressure in the compressed air buffer tank.

[0020] The pressure sensor can monitor the pressure change in the nitrogen buffer tank and / or the compressed air buffer tank in real time, ensure that the gas pressure in the system is within the set safety range, and avoid equipment failure or unstable gas supply caused by excessive or insufficient pressure.

[0021] In an embodiment of the present application, a gas flow detection device is further included for detecting the gas flow at the nitrogen distributor outlet and / or the compressed air buffer tank outlet.

[0022] The gas flow detection device can monitor the flow of nitrogen and / or compressed air in real time, ensure that each work area receives the required amount of precise gas, avoid excessive or insufficient gas supply, and improve gas utilization efficiency.

[0023] In an embodiment of the present application, the gas guide pipe corresponds to the delivery pipe one-to-one.

[0024] The one-to-one layout of the gas guide pipe and the delivery pipe ensures that each gas guide pipe corresponds to a specific gas supply path, facilitating the delivery of compressed air.

[0025] In an embodiment of the present application, a fourth ball valve is provided between the nitrogen generator and the nitrogen buffer tank.

[0026] The fourth ball valve can effectively control the flow of nitrogen from the nitrogen generator to the nitrogen buffer tank. When nitrogen needs to be stored, the fourth ball valve is opened, and nitrogen can flow from the nitrogen generator to the nitrogen buffer tank. When nitrogen does not need to be delivered to the buffer tank, the fourth ball valve is closed, effectively cutting off the gas flow and avoiding unnecessary gas delivery.

[0027] In an embodiment of the present application, a fifth ball valve is provided between the air compressor and the compressed air buffer tank.

[0028] The fifth ball valve can accurately control the flow of compressed air from the air compressor to the compressed air buffer tank. When compressed air needs to be stored, the fifth ball valve is opened to allow compressed air to flow from the air compressor to the compressed air buffer tank. When compressed air does not need to be delivered to the buffer tank, the fifth ball valve is closed to effectively prevent air flow and avoid unnecessary gas storage.

[0029] By using the above technical solutions, the cooperation of the nitrogen buffer tank and the compressed air buffer tank can quickly adjust the gas supply according to different needs in the workshop, and realize efficient supply of nitrogen and compressed air. The first ball valve and the second ball valve ensure flexible switching between the supply of nitrogen and compressed air, avoiding instability and mixing of gas supply. The design of the two buffer tanks effectively combines the storage of nitrogen and compressed air, reduces the volume and configuration complexity of the equipment, and improves resource utilization. At the same time, on the basis of ensuring the quality and stability of the gas supply, the existing gas supply system occupies less space and reduces the management difficulty.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0034] like Figure 1 As shown, in order to achieve the above objectives, this utility model proposes a gas supply system, comprising:

[0035] Nitrogen generator 20 is used to produce nitrogen gas;

[0036] Air compressor 10 is used to provide compressed air;

[0037] A nitrogen buffer tank 40 has an inlet connected to the nitrogen generator 20 for buffering nitrogen generated by the nitrogen generator 20, and an outlet of the nitrogen buffer tank 40 is connected to the workshop through at least one delivery pipe 80.

[0038] The compressed air buffer tank 30 has an air inlet connected to the air compressor 10 and is used to buffer the compressed air generated by the air compressor 10. The air outlet of the compressed air buffer tank 30 is connected to the delivery pipe 80 through the air guide pipe 70.

[0039] The first ball valve 52 is used to open or close the outlet of the nitrogen buffer tank 40; and

[0040] The second ball valve 51 is used to open or close the outlet of the compressed air buffer tank 30 so that only one gas passage is always allowed in the delivery pipe 80.

[0041] Specifically, the main function of the nitrogen generator 20 is to produce nitrogen gas to meet the demand of the workshop. The nitrogen generator 20 extracts nitrogen gas from air through specific separation technology (such as membrane separation or pressure swing adsorption), and ensures that the purity of the produced nitrogen gas meets the standard required by the workshop. The nitrogen gas produced by the nitrogen generator 20 is transported to the nitrogen buffer tank 40 through a pipeline for subsequent use.

[0042] The air compressor 10 compresses air to a certain pressure and supplies it to the workshop.

[0043] The main function of the nitrogen buffer tank 40 is to store the nitrogen gas produced by the nitrogen generator 20, ensuring that the nitrogen gas can meet the demand of the workshop. The gas outlet of the nitrogen buffer tank 40 is connected to the delivery pipe 80, which guides the stored nitrogen gas to the workshop. The role of the nitrogen buffer tank 40 is to balance the gas demand fluctuations between the nitrogen generator 20 and the workshop, ensuring that the workshop can stably obtain the required nitrogen gas at any time.

[0044] The compressed air buffer tank 30 is used to store the compressed air produced by the air compressor 10. The gas inlet of the compressed air buffer tank 30 is connected to the output end of the air compressor 10. When the workshop needs compressed air, the gas is delivered from the buffer tank to the delivery pipe 80 through the gas guide pipe 70, thereby providing the required compressed air to the workshop. The role of the buffer tank is to stabilize the air supply of the workshop, avoiding uneven or fluctuating supply of compressed air.

[0045] The first ball valve 52 is installed at the gas outlet of the nitrogen buffer tank 40, used to control the flow of nitrogen gas. According to the gas demand of the workshop, the first ball valve 52 can be opened or closed to control whether the nitrogen gas enters the delivery pipe 80 and flows to the workshop. When the workshop needs nitrogen gas, the first ball valve 52 is opened to deliver nitrogen gas from the nitrogen buffer tank 40 to the delivery pipe 80; when the workshop does not need nitrogen gas, the first ball valve 52 is closed to prevent nitrogen gas from continuing to flow.

[0046] The second ball valve 51 is installed at the gas outlet of the compressed air buffer tank 30, controlling the flow of compressed air. When the workshop needs compressed air, the second ball valve 51 is opened to allow compressed air to flow from the compressed air buffer tank 30 into the delivery pipe 80 and to the workshop; when the workshop does not need compressed air, the second ball valve 51 is closed to prevent compressed air from flowing into the delivery pipe 80.

[0047] In actual work, the supply of nitrogen and compressed air is provided by nitrogen generator 20 and air compressor 10 respectively. In the specific operation process, when the workshop needs nitrogen, the nitrogen generated by nitrogen generator 20 is stored in nitrogen buffer tank 40, first ball valve 52 is opened to allow nitrogen to flow from nitrogen buffer tank 40 into delivery pipe 80 and sent to the workshop. When the workshop needs compressed air, the compressed air generated by air compressor 10 is compressed and stored in compressed air buffer tank 30, second ball valve 51 is opened to allow compressed air to flow from compressed air buffer tank 30 into delivery pipe 80 and sent to the workshop.

[0048] Importantly, first ball valve 52 and second ball valve 51 are controlled by switches to ensure that only one gas is allowed to pass through delivery pipe 80 at the same time, avoiding cross flow of nitrogen and compressed air, thereby ensuring the accuracy and safety of gas supply.

[0049] With the above technical solution, by using nitrogen buffer tank 40 and compressed air buffer tank 30 in combination, the gas supply can be quickly adjusted according to different needs of the workshop, realizing efficient supply of nitrogen and compressed air. The setting of first ball valve 52 and second ball valve 51 ensures flexible switching between the supply of nitrogen and compressed air, avoiding instability and mixing of gas supply. The design of the two buffer tanks effectively combines the storage of nitrogen and compressed air, reducing the volume and configuration complexity of the equipment, while improving resource utilization. At the same time, on the basis of ensuring the quality and stability of gas supply, the existing gas supply system occupies less space, reducing its management difficulty.

[0050] In an embodiment of the present application, it further comprises:

[0051] A nitrogen distributor 60, the gas inlet of the nitrogen distributor 60 is communicated with the gas outlet of the nitrogen buffer tank 40, the nitrogen distributor 60 is provided with at least two gas outlets for distributing the gas in the nitrogen buffer tank 40 to different positions of the workshop, and the delivery pipe 80 is connected to the gas outlet of the nitrogen distributor 60.

[0052] Specifically, the gas inlet of nitrogen distributor 60 is directly connected to the gas outlet of nitrogen buffer tank 40, thereby introducing the stored nitrogen into nitrogen distributor 60. Nitrogen distributor 60 is provided with at least two gas outlets, the number of which can be increased or decreased according to the actual needs of the workshop, and the gas outlets are connected to each gas use point of the workshop through pipelines.

[0053] The nitrogen distributor 60 has multiple gas outlets, each connected to different gas demand points in the workshop. By adjusting the flow rate of each gas outlet, nitrogen can be accurately distributed to different locations in the workshop to meet the gas needs of different work areas. For example, some processes may require high concentrations of nitrogen, while other locations may have lower demands. The nitrogen distributor 60 achieves this flexible gas distribution through multiple gas outlets. The nitrogen distributor 60 can ensure the stability of gas supply, avoiding the impact of uneven gas flow or pressure fluctuations on production.

[0054] Working principle:

[0055] When the system is working normally, the nitrogen generated by the nitrogen generator 20 is first sent to the nitrogen buffer tank 40 for storage. According to the demand for nitrogen in the workshop, the first ball valve 52 controls whether nitrogen flows out of the nitrogen buffer tank 40. When the workshop needs nitrogen, the first ball valve 52 is opened, and nitrogen flows into the nitrogen distributor 60 through the gas inlet of the nitrogen distributor 60. The nitrogen distributor 60 distributes nitrogen to its multiple gas outlets and delivers it to different work areas in the workshop through the connecting pipelines.

[0056] During this process, the delivery pipe 80 is responsible for delivering the distributed nitrogen to the workshop, ensuring that the gas can be accurately and effectively delivered to the target location. The gas flow of the entire system is controlled by valves and distributors, always maintaining the stability and flexibility of nitrogen supply.

[0057] With the above technical solution, the nitrogen distributor 60 can distribute nitrogen to multiple areas according to the gas needs of different locations in the workshop, ensuring the accuracy of gas supply and avoiding resource waste. The design of multiple gas outlets allows the system to adjust according to the gas needs of different areas in the workshop, meeting the needs of different processes or equipment and improving the adaptability of the system.

[0058] In an embodiment of the present application, each gas outlet of the nitrogen distributor 60 is provided with a third ball valve 90 for opening or closing each gas outlet; wherein the on-off state of the third ball valve 90 corresponding to the delivery pipe 80 is always opposite to that of the second ball valve 51.

[0059] Specifically, each gas outlet on the nitrogen distributor 60 is provided with a third ball valve 90 for controlling whether nitrogen flows through the gas outlet to different locations in the workshop. When the third ball valve 90 is opened, nitrogen can flow out of the gas outlet and be delivered to the corresponding area of the workshop; when the third ball valve 90 is closed, the gas outlet will be closed, preventing nitrogen from flowing. By adjusting the on-off state of each third ball valve 90, the nitrogen distributor 60 can accurately control the flow and distribution of nitrogen.

[0060] The second ball valve 51 controls the flow of compressed air, and its on-off state determines whether compressed air can enter the delivery pipe 80.

[0061] The third ball valve 90 connected with the delivery pipe 80 controls the flow of nitrogen, and its on-off state is always opposite to that of the second ball valve 51, ensuring that only one kind of gas can pass through the delivery pipe 80 at any time, either nitrogen or compressed air. It is ensured that when the workshop needs compressed air, the second ball valve 51 is opened, and the flow of nitrogen in the delivery pipe 80 is blocked; when the workshop needs nitrogen, the second ball valve 51 is closed, and the corresponding outlet of the third ball valve 90 is opened to allow the flow of nitrogen and delivery to the workshop, avoiding the simultaneous flow of nitrogen and compressed air in the same delivery pipe 80, thereby avoiding the problem of gas mixing.

[0062] By adopting the above technical scheme, the reverse control of the third ball valve 90 and the second ball valve 51 ensures that nitrogen and compressed air cannot flow at the same time in the same delivery pipe 80, avoiding the risk of cross-mixing of gases, thereby ensuring the purity and quality of the gas.

[0063] In an embodiment of the present application, a pressure sensor for detecting the gas pressure in the nitrogen buffer tank 40 and / or the gas pressure in the compressed air buffer tank 30 is further included.

[0064] By adopting the above technical scheme, the pressure sensor can monitor the gas pressure change in the nitrogen buffer tank 40 and / or the compressed air buffer tank 30 in real time, ensuring that the gas pressure in the system is within the set safe range, thereby avoiding equipment failure or unstable gas supply caused by excessively high or low pressure.

[0065] In an embodiment of the present application, a gas flow detection member for detecting the gas flow at the outlet of the nitrogen distributor 60 and / or the outlet of the compressed air buffer tank 30 is further included.

[0066] By adopting the above technical scheme, the gas flow detection member can monitor the flow of nitrogen and / or compressed air in real time, ensuring that each working area receives the required accurate amount of gas, avoiding excessive or insufficient gas supply, thereby improving the utilization efficiency of the gas.

[0067] In an embodiment of the present application, the gas guide pipe 70 corresponds to the delivery pipe 80 one-to-one.

[0068] By adopting the above technical scheme, the one-to-one layout of the gas guide pipe 70 and the delivery pipe 80 ensures that each gas guide pipe 70 corresponds to a specific gas supply path, facilitating the delivery of compressed air.

[0069] In an embodiment of the present application, a fourth ball valve 101 is arranged between the nitrogen generator 20 and the nitrogen buffer tank 40.

[0070] The fourth ball valve 101 is arranged to effectively control the nitrogen gas flow from the nitrogen generator 20 to the nitrogen buffer tank 40.

[0071] In an embodiment of the present application, a fifth ball valve 102 is arranged between the air compressor 10 and the compressed air buffer tank 30.

[0072] The fifth ball valve 102 is arranged to accurately control the compressed air flow from the air compressor 10 to the compressed air buffer tank 30. When the compressed air needs to be stored, the fifth ball valve 102 is opened to allow the compressed air to flow from the air compressor 10 to the compressed air buffer tank 30. When the compressed air does not need to be sent to the buffer tank, the fifth ball valve 102 is closed to effectively prevent the air flow, thereby avoiding unnecessary gas storage.

[0073] The above description is only preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, made by using the content of the present application specification and drawings, are included in the patent protection scope of the present application.
