[0023] Please refer to Figures 1-4, an embodiment provided by the present utility model: a drainage device for natural gas extraction, including a device housing 1. One side of the device housing 1 is fixedly installed with an air inlet pipe 12, and one end of the air inlet pipe 12 extends into the interior of the device housing 1. One side below the interior of the device housing 1 is fixedly installed with a partition plate 13, and a filter plate 14 is fixedly installed inside the partition plate 13. One side of the partition plate 13 is fixedly installed with a fixed seat 10, and the fixed seat 10 is fixedly connected to the device housing 1. The fixed seat 10 extends to the outside of the device housing 1. Above one side of the fixed seat 10, an electric cylinder two 9 is fixedly installed. Inside the partition plate 13, a scraper 11 is arranged, and the push rod end of the electric cylinder two 9 penetrates through the fixed seat 10 and is fixedly connected to the scraper 11.

[0024] During use, the electric cylinder two 9 can drive the scraper 11 to move. Then, through the movement of the scraper 11, the surface of the filter plate 14 can be scraped and cleaned, removing the debris and impurities attached to the surface of the filter plate 14, facilitating the stable flow of natural gas and increasing the practicality of the device.

[0025] Furthermore, at the bottom inside the device housing 1, an aggregate trough 15 is fixedly installed. Inside the aggregate trough 15, an aggregate box 16 is arranged. One end of the aggregate box 16 extends to one side end face of the device housing 1. The two sides above the inside of the aggregate trough 15 are set as inclined surfaces, facilitating the debris and impurities to slide into the aggregate box 16.

[0026] Furthermore, below one side of the device housing 1, an electric cylinder one 8 is fixedly installed. The push rod end of the electric cylinder one 8 extends into the interior of the device housing 1 and is fixedly connected to the aggregate box 16. By driving the aggregate box 16 to be pushed out of the device housing 1 by the electric cylinder one 8, the convenience of cleaning debris and impurities is increased. Above one side of the aggregate box 16, a baffle 17 is fixedly installed. The upper end face of the aggregate box 16 is flush with the upper end face of the baffle 17. One end of the baffle 17 extends to the outside of the device housing 1, such that when driving the aggregate box 16 to move, the baffle 17 will be driven to move, facilitating the shielding of the lower part inside the aggregate trough 15 to prevent debris from falling in and increasing the practicality.

[0027] Furthermore, above the interior of the device housing 1, a flow collecting cover 18 is fixedly installed. Above the flow collecting cover 18, a conveying pipe one 19 is fixedly installed. Above the device housing 1, a top groove 101 is arranged. Inside the top groove 101, a condensation box 2 is arranged. Above the condensation box 2, an output pipe 3 is fixedly installed. One end of the conveying pipe one 19 away from the flow collecting cover 18 is fixedly connected to the condensation box 2.

[0028] Furthermore, the interior of the condensation box 2 is provided with an inner cavity 201 and an outer cavity 202, and the outer cavity 202 is arranged outside the inner cavity 201. The inner cavity 201 is communicated with the first conveying pipe 19 and the output pipe 3. Above one side of the condensation box 2, a cold air output pipe 22 is fixedly installed, and below one side of the condensation box 2, a cold air input pipe 21 is fixedly installed. Both the cold air input pipe 21 and the cold air output pipe 22 are communicated with the outer cavity 202 of the condensation box 2. Thus, cold air is conveyed into the outer cavity 202 through the cold air input pipe 21. Through heat transfer, the interior of the inner cavity 201 of the condensation box 2 is at a low temperature, which facilitates the liquefaction and removal of water vapor in the natural gas, increases the water removal in natural gas extraction, and enhances the practicability.

[0029] Furthermore, a layer board 4 is fixedly installed below one side of the device housing 1, and a water tank 5 is fixedly installed above the layer board 4. One side of the interior of the device housing 1 is provided with a second conveying pipe 20. The upper end of the second conveying pipe 20 is fixedly connected to the condensation box 2, and the lower end of the second conveying pipe 20 is fixedly connected to the water tank 5. Below one side of the water tank 5, a drain pipe 6 is fixedly installed, and a valve is arranged on the drain pipe 6, which facilitates the control of the discharge of the water body in the water tank 5.

[0030] Furthermore, support plates 7 are symmetrically and fixedly installed at the front end and the rear end below the layer board 4 respectively, which can support the layer board 4 and enhance the stability of the layer board 4.

[0031] Working principle: When in use, the extracted natural gas is input into the device housing 1 through the air inlet pipe 12. Through the function of the filter plate 14, the natural gas is filtered, and the debris and impurities in the natural gas are retained and removed. The electric cylinder two 9 is used to drive the scraper 11 to move, scrape the surface of the filter plate 14, and remove the debris and impurities attached to the surface of the filter plate 14, which facilitates the stable flow of the natural gas. The filtered debris and impurities fall into the aggregate box 16 for storage. Then, the natural gas flows into the inner cavity 201 of the condensation box 2 through the flow collector 18 and the first conveying pipe 19. Through the low temperature of the condensation box 2, the water vapor in the natural gas is liquefied and removed. Then, the natural gas is output through the output pipe 3, and the water body flows into the water tank 5 through the second conveying pipe 20 for storage, and can be discharged by opening the valve on the drain pipe 6.
