Description

Technical Field

[0001] The utility model relates to the technical field of methane purification, in particular to an automatic gas supply system for methane purification equipment. Background Art

[0002] The methane produced often contains other impurities. If the methane is impure, it may explode. In addition, high concentrations of methane will replace oxygen in the air, causing an oxygen-deficient environment, which is harmful to human health and even life-threatening. Therefore, it is very necessary to purify the methane after production. However, the high-temperature and high-pressure production environment directly transported to the back-end purification equipment is prone to damage to the purification device. If the gas pressure is too low, the purification effect will be reduced and the production time will be extended. Utility Model Content

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-Figure 3 As shown, the purpose of this embodiment is to provide an automatic gas supply system for methane purification equipment, including a main shell 1, one end of the main shell 1 is fixedly installed with a first baffle 3, the end of the main shell 1 away from the first baffle 3 is fixedly installed with a second baffle 31, and the side of the second baffle 31 away from the main shell 1 is fixedly installed with multiple air intake pipes 7, and the air intake pipes 7 are connected to an external methane preparation device.

[0022] A plurality of transition shells 2 distributed in a ring are fixedly installed at the outer circle of one end of the main shell 1. There is a cavity inside the transition shell 2. Both ends of the transition shell 2 are set to be rounded. The cavity is connected to the interior of the main shell 1. The rounded corners can reduce the resistance encountered by the gas when passing through the transition shell 2, making the transition shell 2 streamlined and improving the gas passage rate.

[0023] The inner sliding card of the main shell 1 is provided with a sealing plate 4 and a moving plate 5, the sealing plate 4 divides the main shell 1 into a first chamber and a second chamber, a plurality of spring telescopic rods 53 distributed in an annular shape are fixedly installed between the sealing plate 4 and the moving plate 5, a screw rod 6 is provided in the middle of the moving plate 5, a center bracket 52 is fixedly installed in the middle of the moving plate 5, the screw rod 6 is installed in the middle of the center bracket 52 through a thread hole, the sealing plate 4 is located on the side of the transition shell 2 close to the second baffle 31, and the moving plate 5 is located on the side of the transition shell 2 away from the second baffle 31. When the gas enters the interior of the main shell 1 through the air inlet pipe 7, the sealing plate 4 is The spring telescopic rod 53 pushes and is located in the initial position, and the first chamber is in a sealed state. When the gas entering the main shell 1 gradually increases, its pressure also gradually increases. When the thrust generated by the air pressure is greater than the thrust brought by the spring telescopic rod 53, the sealing plate 4 is pushed and then displaced toward the transition shell 2. At this time, the gas can pass through the transition shell 2 from the first chamber to the inside of the second chamber. When the air pressure inside the first chamber gradually increases, the sealing plate 4 gradually approaches the middle of the transition shell 2. When the sealing plate 4 is located in the middle of the transition shell 2, the maximum equilibrium state is reached at this time, and the pressure and flow rate of the first chamber and the second chamber are equal.

[0024] By setting up the sealing plate 4, the device can adaptively adjust the gas pressure. If the gas pressure is too low, it will be pressurized before entering the next production process. If the gas pressure is too high and the flow rate is too fast, the sealing plate 4 can also play a buffering role to prevent the high gas pressure and flow rate from causing damage to the rear-end equipment. Pressurizing the low-pressure gas makes the rear-end purification efficiency higher, making the device more practical and having a wider range of applications.

[0027] Because the gas pressure flow rates output by different preparation devices are different, and the amount of raw material used and the temperature can cause the output gas volume to change, a hexagonal connector 63 is provided, and a wrench is used to rotate the hexagonal connector 63, which drives the second gear 62 and the first gear 61 to rotate and then drives the screw 6 to rotate, thereby causing the movable plate 5 to move, and then adjusting the strength of the spring telescopic rod 53, so that the device can adapt to a wider range of gas pressures, can automatically adapt to more devices, has a simple structure, is easy to operate, and has low maintenance costs.

[0028] A plurality of evenly distributed sliders 51 are fixedly mounted on the outer ring of the movable plate 5, and a plurality of first slide grooves 11 corresponding to the sliders 51 are opened on the inner wall of the main shell 1. The sliders 51 are slidably clamped inside the first slide grooves 11. The sliders 51 are arranged so that the movable plate 5 can move stably without shaking, thereby making the operation of the device more stable.

[0029] By setting the pressure limiting valve 81, when the second chamber is lower, the gas cannot pass through the second output pipe 9, and will flow out from the inside of the first output pipe 8. When the air pressure is strong, the second output pipe 9 is in an open state. The first output pipe 8 and the second output pipe 9 can be connected to different back-end purification equipment, which plays a role of secondary protection and further protects the safety of the device.
