[0036] Specifically, in the horizontal well integrated negative pressure gas recovery device, when the gas flow is filtered, the gas is introduced from the gas inlet pipe 2, the vacuum pump 6 starts to work, the power is adjusted to effectively control the pressure in the device, and then the gas is orderly flowed to be filtered through the filter plate 16, the filtered gas is guided to the inside of the collection tank 1 through the guide pipe 7 for collection and storage, when the gas flow passes through the guide pipe 7, the impact force of the gas flow pushes the rubber plug 8 to move, the rubber plug 8 drives the connecting column 9 to move in the moving process, the connecting column 9 drives the limiting disc 13 to slide in the connecting shell 11, and the limiting disc 13 compresses the spring 10 in the process, when the gas flow ends and loses the pushing effect, the spring 10 rebounds relying on the elastic potential energy, drives the rubber plug 8 to rebound to the original position quickly, closes the guide pipe 7 in time, effectively prevents the gas backflow caused by untimely closing, and ensures the stable operation of the gas recovery device.

[0037] With reference to Figure 1 , Figure 4 and Figure 5 , the disassembling and assembling assembly includes a sealing plate 15 fixedly connected to the outer wall of the filter plate 16, the sealing plate 15 is made of high-strength engineering plastic, which not only has good corrosion resistance, but also can withstand certain pressure and impact force, to ensure stability during operation of the device. The sealing plate 15 is fixedly connected to the outer wall of the filter plate 16, and the two are sealed by a sealing rubber strip to prevent gas leakage. The sealing plate 15 is fixedly connected with a connecting plate 4 on one side, the connecting plate 4 is provided with a pulling groove 3 in the inside, the surface of the pulling groove 3 is smoothly treated, which is convenient for the staff to pull by hand, and the shape design conforms to the principle of human engineering, which can provide comfortable holding feeling and facilitate force operation. The sealing plate 15 is provided with a limiting groove 14 in the inside, the sealing plate 15 is slidingly connected with a limiting column 19 in the inside, one end of the limiting column 19 is fixedly connected with a limiting plate 18, the limiting plate 18 is slidingly connected to the outer wall of the limiting groove 14, a clamping plate 17 is fixedly connected to one side of the limiting groove 14, the clamping plate 17 is slidingly connected to the inner wall of the filter box 5, the filter box 5 is provided with a gas inlet pipe 2 on one side, a spring 20 is sleeved on the outer wall of the limiting column 19, one end of the spring 20 is fixedly connected to the inner wall of the limiting groove 14, the other end of the spring 20 is fixedly connected to the outer wall of the limiting plate 18, and one end of the limiting column 19 is fixedly connected with a limiting ring 21, the limiting ring 21 is slidingly connected to the inner wall of the sealing plate 15.

[0038] Specifically, after the integrated negative pressure gas recovery device of the horizontal well is operated for a long time, the staff can pull the pull groove 3 to drive the connecting plate 4 to move, and then the connecting plate 4 drives the sealing plate 15 to slide inside the filter box 5. Because the surface of the clamping plate 17 is designed as an inclined surface, when the sealing plate 15 slides, the inclined surface structure pushes the clamping plate 17 to slide inward. The movement of the clamping plate 17 drives the limiting plate 18 to slide inside the limiting groove 14. At the same time, the limiting plate 18 drives the limiting column 19 to move. In this process, the limiting column 19 compresses the spring 2 20, so that the sealing plate 15 can be smoothly taken out. The staff can clean or maintain the filter plate 16. After the maintenance is completed, the sealing plate 15 is put back to the original position. At this time, the spring 2 20 rebounds, driving the clamping plate 17 to rebound to the inside of the filter box 5, thereby accurately fixing the filter plate 16, ensuring that the filter plate 16 can stably play a role in subsequent work and continuously dry and efficiently filter the gas.

[0039] Working principle: when filtering the gas flow, the gas is introduced through the air inlet pipe 2, then adjusted by the vacuum pump 6, filtered through the filter plate 16, and then guided by the guide pipe 7 to the inside of the collection tank 1 for collection. When the gas flow passes, it pushes the rubber plug 8 to move, then drives the connecting column 9 to move by the rubber plug 8, and then drives the limiting disc 13 to slide inside the connecting shell 11 by the connecting column 9, compressing the spring 1 10. When the gas flow ends, the spring 1 10 rebounds to drive the rubber plug 8 to rebound to the original position, thereby closing it to prevent the gas from flowing back due to untimely closing.

[0040] In addition, when the use time is too long, the pull groove 3 can be pulled during maintenance to drive the connecting plate 4 to move, then drive the sealing plate 15 to slide inside the filter box 5 by the connecting plate 4. Because the surface of the clamping plate 17 is an inclined surface, the clamping plate 17 is pushed to slide inward to drive the limiting plate 18 to slide inside the limiting groove 14. Then, the limiting plate 18 drives the limiting column 19 to move to compress the spring 2 20, so that the sealing plate 15 can be taken out. The filter plate 16 is cleaned or maintained, and then put back. The spring 2 20 rebounds to drive the clamping plate 17 to rebound to the inside of the filter box 5 to fix the filter plate 16 and keep stable and dry filtering.

[0041] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features.
