Description

Technical Field

[0001] The utility model relates to the technical field of gas extraction, in particular to a gas extraction device suitable for gas management. Background Art

[0002] Gas refers to harmful gases mainly composed of methane in mines, which are mainly composed of coal-bed methane. Sometimes methane is referred to alone. It is a colorless, tasteless, odorless gas that can burn or explode. It is insoluble in water and has higher diffusivity than air. Gas can cause harm when the concentration is high, so it needs to be controlled. At present, a gas extraction device is used for gas control. The gas extraction device generally includes a vacuum pump to extract the gas, and a fan is used to pass the gas into the filter box for filtration to achieve the purpose of control.

[0003] A Chinese patent discloses a gas extraction device for coal mine gas control (authorization announcement number CN214330682U). When extracting gas, the patented technology first turns on the fan and the vacuum pump at the same time, and the gas enters the filter box through the air inlet pipe and the air outlet pipe, and then is extracted by the vacuum pump and discharged into the gas storage tank for storage. The gas passes through the filter plate to filter out dust particles. While filtering, the motor is turned on, and the elliptical wheel will rotate, so that the filter plate forms an up and down vibration movement. The dust particles are shaken into the filter box to keep the filter plate unobstructed. After the extraction work is completed, the sealed door can be opened to clean the dust particles in the filter box. The elliptical wheel and filter plate set in this device can filter the dust particles in the gas, thereby improving the purity of the gas extraction.

[0004] However, there are still some shortcomings in this patent. Although this patent can manage gas extraction, it can be seen from the drawings of this patent that this patent cannot process the dust shaken off when the gas passes through the filter plate, which causes the gas inlet pipe to be blocked, thereby affecting the gas extraction and management work. Therefore, those skilled in the art provide a gas extraction device suitable for gas management to solve the problems raised in the above background technology. Utility Model Content
