Gas pre-processing and sampling collector of underground mine containing large amount of dust

Abstract

The invention provides a gas pre-processing and sampling collector of an underground mine containing a large amount of dust, and relates to the field of mines. The gas pre-processing and sampling collector comprises a support bottom plate and a spherical shell, wherein a air-blowing control mechanism is arranged in the spherical shell, a side-surface support plate is welded onto a surface of the support bottom plate, a handle is welded onto a surface of the side-surface support plate, a liquid-gas collection mechanism is arranged on the surface of the side-surface support plate, and a storagebattery is arranged on the surface of the side-surface support plate. In the gas pre-processing and sampling collector of the underground mine containing a large amount of dust, an arc baffle body isarranged, on one hand, a second suction pipe can be matched with an arc sealing plate to guide an air direction, so that the air direction is in chaos; and on the other hand, a surface of the arc baffle body can be used for diverting water, so that the water can flow to an inner wall of the spherical shell and flows along the inner wall of the spherical shell, and the problems that a conventionalgas sampling device is not convenient to pre-process and subsequent sample detection is easily affected are effectively solved.

Description

technical field [0001] The invention relates to the technical field of mines, in particular to a sampling collector used for gas pretreatment in underground mines containing a large amount of dust. Background technique [0002] The mine is not only a place where minerals can be mined, but also an important workplace. The internal environment of the mine is very complicated, and various protections need to be done when working in the mine. Not only that, but also the gas in it needs to be protected during the safety maintenance of the mine. For analysis, it is necessary to analyze the gas composition. [0003] Although the current portable gas detection device can analyze the gas to a certain extent, after all, the structure is simple, the detection range and content are relatively limited, and the accuracy is also affected, so it is necessary to frequently collect the gas in the underground mine and the gas in the gas. Solid, and then brought up, the current collection devi...
