Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a bypass type gas pipeline rapid slag discharger. Background Art

[0002] During coal mining, the gas in the coal seam must be extracted first to ensure the safety of mining and avoid gas explosion accidents. During the extraction process, gas is often accompanied by coal slag and accumulated water, which narrows the extraction pipeline and reduces the efficiency of gas extraction.

[0003] It is necessary to clean the coal slag and accumulated water in the pipeline in time. In addition, when dealing with the coal slag and accumulated water, the pump needs to be stopped and the gas pipeline needs to be dismantled to remove the slag, which results in a long maintenance time, which not only affects the production of the working face, but also wastes manpower and material resources. The long maintenance time will also cause the gas in the working face to exceed the limit, which poses a great safety hazard to high-gas mines.

[0004] The existing gas pipeline slag removal device must shut down the gas extraction system when removing slag, which is very likely to cause gas over-limit, making mine gas control extremely difficult. It is impossible to centrally clean up the debris, the slag removal speed is slow, and manpower and material resources are wasted. The existing slag removal pipelines are all installed in the pump station, the location is limited, and the slag cannot be effectively removed. The amount of slag cannot be monitored, and it is difficult to judge whether to clean it. Therefore, the utility model proposes a bypass gas pipeline fast slag discharger. Utility Model Content

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0016] Reference Figure 1 , a bypass type gas pipeline quick slag discharger comprises a gas pipeline 11 and a box-type slag discharger 5, the box-type slag discharger 5 is installed on the gas pipeline 11, a drain port 4 and a liquid level gauge 8 are provided on the box-type slag discharger 5, a filter is provided at the gas outlet end of the box-type slag discharger 5, the slag discharge port of the box-type slag discharger 5 is closed with a blind plate, a butterfly valve 3 7 is provided on the box-type slag discharger 5, a bypass pipeline 1 is connected in parallel to the gas pipeline 11, and the bypass pipeline 1 is connected to both ends of the box-type slag discharger 5, valves are respectively provided on the bypass pipeline 1 and the air inlet and air outlet ends of the box-type slag discharger 5, and a pressure sensor is also provided on the gas pipeline 11 and at the installation position of the filter.

[0017] Furthermore, the valve includes butterfly valve 1 3 , butterfly valve 2 6 , and butterfly valve 4 9 , butterfly valve 2 6 is installed on the bypass pipeline 1 , and butterfly valve 1 3 and butterfly valve 4 9 are installed at the air inlet and outlet ends of the box-type slag discharger 5 .

[0018] Furthermore, the pressure sensor includes a pressure sensor 1 2 and a pressure sensor 2 10 , wherein the pressure sensor 1 2 is installed near the air inlet end of the box-type slag discharger 5 , and the pressure sensor 2 10 is installed near the air outlet end of the box-type slag discharger 5 .

[0019] The working principle of the utility model is as follows: when in use, the utility model is installed at any position of the gas pipeline 11 as needed when installing the gas pipeline 11. After installation, the butterfly valve 2 6 of the bypass pipeline 1 of the utility model is closed, and the butterfly valve 1 3 and the butterfly valve 4 9 on the gas pipeline 11 are opened to open the gas extraction and discharge system. After the system has been running for a period of time, when debris passes through the utility model, it will be blocked by the filter and automatically accumulated in front of the filter. When the accumulated volume of the debris exceeds half of the pipeline, the gas flow rate in the pipeline will increase, and the pressure generated will also increase relatively. At this time, the pressure change can be intuitively seen through the pressure sensor 1 2 and the pressure sensor 2 10 installed at the filter, and then it can be determined whether the accumulation of debris in the gas pipeline is serious.

[0020] When removing slag, first open the butterfly valve 2 6 of the upper bypass pipeline 1 of the utility model, and then close the butterfly valve 1 3 and the butterfly valve 4 9 on the gas pipeline 11. At this time, the gas passes through the upper bypass pipeline 1, and the gas pipeline 11 can perform the slag removal work without stopping the gas extraction and discharge system. Open the blind plate on the slag discharge port of the box-type slag discharger 5 on the gas pipeline 11, clean up the debris, and then restore to the original state.
