[0025] See Figure 1 The preferred embodiment of the utility model provides a flammable and explosive gas processing device, including a bus 1, a gas mixing tank 2, a first air control valve 3, a second air control valve 4, a compressed air input piece 5, and an inert gas input piece 6; the bus 1 is used to connect to flammable and explosive gases; the gas mixing tank 2 is connected to the bus 1; the first air control valve 3 is connected to the gas mixing tank 2; the second air control valve 4 is connected to the bus 1; the compressed air input piece 5 is used to connect to positive pressure compressed air, and the compressed air input piece 5 is connected to both the first air control valve 3 and the second air control valve 4; the inert gas input piece 6 is used to connect to inert gas, and the inert gas input piece 6 is connected to both the first air control valve 3 and the second air control valve 4. The bus 1 is connected to flammable and explosive gases, the compressed air input part 5 is connected to positive pressure compressed air, and the inert gas input part 6 is connected to inert gas. The compressed air input part 5 regulates and filters the positive pressure compressed air. The positive pressure compressed air is used to ensure the normal operation of the first air control valve 3 and the second air control valve 4. The inert gas enters the gas mixing tank 2 and the bus 1 through the first air control valve 3 and the second air control valve 4. The bus 1 contains both flammable and explosive gases and inert gases, thereby reducing the concentration of flammable and explosive gases in the bus 1. Then the flammable and explosive gases and inert gases in the bus 1 are transported to the gas mixing tank 2, and the inert gas input part 6 transports inert gas to the gas mixing tank 2 through the first air control valve 3. The inert gas and flammable and explosive gases are mixed in the gas mixing tank 2, further reducing the concentration of flammable and explosive gases. The mixed gas composed of flammable and explosive gases and inert gases is then transported to the gas treatment equipment through the gas mixing tank 2 for purification. This device dilutes the concentration of flammable and explosive gases by adding inert gas, so that the concentration of flammable and explosive gases is within the safety threshold during the entire transportation process, which can prevent explosions.

[0026] The flammable and explosive gas processing device also includes two flow regulating valves 11 and two gas detectors 12. The two flow regulating valves 11 are respectively connected between the first gas control valve 3 and the gas mixing tank 2 and between the second gas control valve 4 and the bus 1. The two flow regulating valves 11 are respectively used to adjust the flow rate of the inert gas flowing into the bus 1 and the gas mixing tank 2, so that the amount of inert gas input into the bus 1 and the gas mixing tank 2 is within an appropriate range.

[0027] Specifically, the two gas detectors 12 are respectively connected to the bus 1 and the gas mixing tank 2; the output ends of the two gas detectors 12 are respectively electrically connected to the input ends of the two flow regulating valves 11, and the two gas detectors 12 are respectively used to detect the concentrations of flammable and explosive gases in the bus 1 and the gas mixing tank 2, and send the measured concentration values ​​to the two flow regulating valves 11 in the form of signals. If the concentration value is too low, the two flow regulating valves 11 reduce the flow rate of the inert gas to avoid wasting too much inert gas. If the concentration value is too high, the two flow regulating valves 11 increase the flow rate of the inert gas to avoid failing to achieve the effect of preventing explosion.

[0028] The flammable and explosive gas processing device further includes a solenoid valve 13, through which the first and second air-controlled valves 3 and 4 are connected to the compressed air input member 5. The solenoid valve 13 is used to adjust the flow rate of the positive-pressure compressed air flowing to the first and second air-controlled valves 3 and 4 to keep it within an appropriate range.

[0029] The flammable and explosive gas treatment device also includes a three-way pipe joint 14, whose three interfaces are respectively connected to the first gas-controlled valve 3, the second gas-controlled valve 4 and the inert gas input part 6. After the inert gas input part 6 is connected to the inert gas, the inert gas can be transported to the three-way pipe joint 14. The three-way pipe joint 14 can change the flow direction of the inert gas so that part of the inert gas flows to the first gas-controlled valve 3 and the other part flows to the second gas-controlled valve 4.

[0030] The busbar 1 is connected to the flammable and explosive gas through a vacuum pipe 15 . Negative pressure can be formed in the vacuum pipe 15 , so that the flammable and explosive gas can be drawn into the busbar 1 .

[0031] The compressed air input component 5 includes a triplet 16, which can filter the positive-pressure compressed air received and stabilize the positive-pressure compressed air so that its air pressure is in a constant state. The triplet 16 can also generate oil mist, which can lubricate the solenoid valve 13 and greatly extend the service life of the solenoid valve 13.

[0032] The inert gas inlet 6 includes a double-joint 17, which filters the incoming inert gas to improve its purity. It also stabilizes the pressure of the inert gas, maintaining a constant pressure. The double-joint 17 does not generate oil mist, ensuring the purity of the inert gas.

[0033] The preferred embodiment of the present invention further provides a lithium battery production system, comprising production equipment, a gas collector 18, and the flammable and explosive gas processing device of the above-described embodiment. The production equipment is used to produce lithium batteries, and the gas collector 18 is used to collect flammable and explosive gases generated by the production equipment during the production of lithium batteries. The gas collector 18 is connected to the bus 1. Specifically, the gas collector 18 is connected to the bus 1 via a vacuum pipe 15. After the gas is collected by the gas collector 18 during the production of lithium batteries, the gas is transported to the bus 1 via the vacuum pipe 15. The concentration of the flammable and explosive gas is diluted by adding inert gas to the bus 1 and the gas mixing tank 2, so that the concentration of the flammable and explosive gas is within a safe threshold during the entire transportation process, thereby preventing explosions.

[0034] The lithium battery production system also includes an air compressor and an inert gas device. The air compressor is connected to the compressed air input part 5 and is used to deliver positive pressure compressed air to the compressed air input part 5. The inert gas device is connected to the inert gas input part 6 and is used to deliver inert gas to the inert gas input part 6. The lithium battery production system can realize the automatic input of positive pressure compressed air and inert gas, and is easy to use.

[0035] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
