Description

Technical Field

[0001] This utility model relates to the field of coal mine gas technology, specifically a gas extraction device for coal mine gas control. Background Technology

[0002] Gas drainage is a measure that uses specialized equipment to extract or discharge combustible gas from coal seams, rock strata, and goafs. When the gas emission volume in a coal mine is large and it is difficult to dilute and remove by ventilation, drainage can be used to remove the gas and reduce the burden on ventilation. Gas drainage usually involves building a gas pumping station at the bottom, which is connected to the drainage borehole through an underground gas drainage pipeline system. When the pump is running, it creates negative pressure, extracting the gas and sending it into a gas tank or directly supplying it to users.

[0003] Existing gas drainage devices for coal mine gas control tend to accumulate dust in pipelines during long-term gas drainage. Therefore, filters are used inside the pipelines to filter the dust, which then accumulates on the surface of the filters. However, since the filters need to be disassembled, they cannot be disassembled during gas transportation, making the disassembly and assembly of some filters inconvenient. To address this, we propose a gas drainage device for coal mine gas control. Utility Model Content

[0004] The purpose of this utility model is to provide a gas drainage device for coal mine gas control, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas extraction device for coal mine gas control, comprising an extraction component, a monitoring component, a protective component, and an interface pipe. The monitoring component is provided on one side of the extraction component, and the protective component is provided inside the side of the monitoring component. The interface pipe is provided at the end of the monitoring component. The protective component includes an internal tube, a slot, an elastic buckle, and a screen plate. The slot is provided on one side of the internal tube, the elastic buckle is provided inside the slot, and the screen plate is provided on the side of the slot.

[0006] Furthermore, the screen plate forms an engaging structure with the built-in tube through a slot, and the slot and the elastic buckle are integrated.

[0007] Furthermore, there are two screen plates, and the screen plates are movably connected to the built-in tube.

[0008] Furthermore, the monitoring component includes a connecting pipe, a monitoring valve, and a warning light, with the monitoring valve located at the top of the connecting pipe and the warning light located at the top of the monitoring valve.

[0009] Furthermore, the connecting pipe is symmetrically arranged along the suction assembly, and the monitoring valve and the connecting pipe are integrated.

[0010] Furthermore, the suction assembly includes a first tube, a pressurizing chamber, a second tube, and a closing valve. The pressurizing chamber is located on the side of the first tube, the second tube is located on the side of the pressurizing chamber, and the closing valve is located at the end of the second tube.

[0011] Furthermore, the second pipe body is connected to the monitoring component, and the shut-off valve cooperates with the monitoring component.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: gas is extracted through a combined pipeline, the second pipe is connected to the connecting pipe, and a sealing valve is set at the connection to facilitate the subsequent disassembly and assembly of the screen plate inside the connecting pipe on one side. The built-in screen plate adopts an embedded and clamping type for easy subsequent disassembly and assembly. The gas content in the pipeline is monitored by a monitoring valve in the middle, which facilitates the immediate disassembly of the screen plate for cleaning and maintenance. Since multiple screen plates are set inside the connecting pipe, and the screen plates are one coarse and one fine plate, the gas passes through the double filter plates to filter coal particles, purifying the gas and improving the purity of the subsequently extracted gas.

[0013] The second pipe is connected to the connecting pipe. Since there are two connecting pipes, a sealing valve is installed at the connection between the second pipe and the connecting pipe to seal off one side of the connecting pipe, control the gas flow, and facilitate the disassembly and assembly of the screen plate inside the other side of the connecting pipe, ensuring the purity of the extracted gas.

[0014] Gas is extracted through a combined pipeline. The gas is absorbed by an end-of-pipe adsorption device, allowing the gas to flow within the combined pipeline. Because the connecting pipe is equipped with multiple screen plates, with one coarse and one fine screen plate, the gas passes through the double filter plates to filter coal particles, purifying the gas and improving the purity of the subsequently extracted gas.

[0020] like Figure 1-2 As shown, a gas drainage device for coal mine gas control includes a suction component 1, a monitoring component 2, a protective component 3, and an interface pipe 4. The monitoring component 2 is located on one side of the suction component 1, and the protective component 3 is located inside the side of the monitoring component 2. The interface pipe 4 is located at the end of the monitoring component 2. The suction component 1 includes a first pipe body 101, a pressurization chamber 102, a second pipe body 103, and a shut-off valve 104. The pressurization chamber 102 is located on the side of the first pipe body 101, and the second pipe body 103 is located on the side of the pressurization chamber 102. A shut-off valve 104 is provided at the end of the second pipe 103. The second pipe 103 is connected to the monitoring component 2, and the shut-off valve 104 cooperates with the monitoring component 2. The second pipe 103 is connected to the connecting pipe 201. Since there are two connecting pipes 201, a shut-off valve 104 is provided at the connection between the second pipe 103 and the connecting pipe 201 to close one side of the connecting pipe 201, control the gas flow direction, and facilitate the disassembly and assembly of the screen plate 304 inside the other side of the connecting pipe 201 to ensure the purity of the gas extraction.

[0021] like Figure 3-4As shown, a gas drainage device for coal mine gas control includes a protective component 3 comprising an internal pipe 301, a slot 302, an elastic buckle 303, and a screen plate 304. The internal pipe 301 has a slot 302 on one side, an elastic buckle 303 inside the slot 302, and a screen plate 304 on the side of the slot 302. The screen plate 304 engages with the internal pipe 301 via the slot 302, and the slot 302 and the elastic buckle 303 are integrally formed. The internal pipe 301 is located inside a connecting pipe 201, and the side of the internal pipe 301 is fixed... A slot 302 is provided to facilitate the insertion of the top two sides of the screen plate 304 into the slot 302. Because the slot 302 has an elastic buckle 303 inside, the screen plate 304 is secured during insertion by the elastic buckle 303, ensuring a stable installation of the screen plate 304. This embedded, securing design facilitates subsequent disassembly and assembly of the screen plate 304, preventing blockages that could affect gas flow. Two screen plates 304 are provided, and the screen plates 304 are movably connected to the built-in pipe 301. Gas is extracted through the combined pipe system and discharged by the end-of-pipe adsorption device. The gas is absorbed and flows within the combined pipe body. Because the connecting pipe 201 is equipped with multiple screen plates 304, one coarse and one fine, the gas passes through these double filter plates, filtering out coal particles and purifying the gas, thus improving the purity of the subsequently extracted gas. The monitoring component 2 includes the connecting pipe 201, a monitoring valve 202, and a warning light 203. The monitoring valve 202 is located at the top of the connecting pipe 201, and the warning light 203 is located at the top of the monitoring valve 202. The connecting pipe 201 is symmetrically arranged along the suction component 1, and the monitoring valve 202 is connected to the connecting pipe 201. The connecting pipes 201 are integrated, and the end of the second pipe body 103 is connected to the connecting pipe 201. A monitoring valve 202 is installed in the middle of the connecting pipe 201. When it is necessary to disassemble and clean the screen plate 304 inside the connecting pipe 201, the connecting pipe 201 is closed by the closing valve 104. At the same time, the internal gas is extracted by the small suction pipe at the end. The monitoring element inside the monitoring valve 202 monitors the gas content in the pipeline. Then, the warning light 203 at the top flashes to indicate the content inside the pipeline, which facilitates the immediate disassembly of the screen plate 304 for cleaning and maintenance.

[0022] Working principle: First, the gas is extracted through the combined pipeline and absorbed by the end adsorption device. The function of the pressurization chamber 102 is to increase the exhaust pressure and maintain normal transportation, so that the gas flows in the combined pipe body. The second pipe body 103 is connected to the connecting pipe 201. At the same time, a sealing valve 104 is set at the connection to facilitate the subsequent disassembly and assembly of the screen plate 304 in the connecting pipe 201 on one side.

[0023] Because a monitoring valve 202 is installed in the middle of the connecting pipe 201, when it is necessary to disassemble and clean the screen plate 304 inside the connecting pipe 201, the connecting pipe 201 is closed by the two side closing valves 104, and the internal gas is extracted by the small suction pipe at the end. The gas content in the pipe is monitored by the monitoring element inside the monitoring valve 202, and then the warning light 203 at the top flashes to indicate the gas content inside the pipe, which facilitates the immediate disassembly of the screen plate 304 for cleaning and maintenance.

[0024] Because the connecting pipe 201 is equipped with multiple screen plates 304, and the screen plates 304 are one coarse and one fine plate, the gas passes through the double filter plates to filter coal particles and purify the gas.

[0025] The built-in tube 301 is located inside the connecting tube 201, and the side of the built-in tube 301 is fixed with a slot 302, which makes it easy for the top two sides of the screen plate 304 to be embedded in the slot 302. Since the slot 302 is provided with an elastic buckle 303, the screen plate 304 is pressed by the elastic buckle 303 during the embedding process. The embedded pressing method facilitates the subsequent disassembly and assembly of the screen plate 304.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
