Problems solved by technology

[0003] At present, the existing air-curtain collaborative dust removal technology needs to cooperate with the draw-out air duct, dust removal fan or dust collector to achieve high-efficiency dust removal effect, and the draw-out dust removal equipment is likely to cause the risk of gas accumulation and explosion. Therefore, the existing wind-mist double-screen dust removal technology It cannot be directly applied to gas mines, which increases the difficulty of dust removal in the tunneling face of gas mines
The existing air curtains are mainly dust-proof, and the angle of the air curtain is fixed, so it cannot be fine-tuned according to the specific scene

Abstract

The invention relates to the technical field of underground air curtain generation, in particular to an adjustable underground air curtain device and application thereof. The device is composed of a fan, a quick connecting pipe, a quick connector, a jet flow inlet, a jet flow outlet, a hose, a jet flow cavity, a jet flow box, a jet flow cavity inner guide vane angle regulator and a fixing support. In the actual application process, the number of the air curtains can be controlled by increasing or decreasing the jet flow cavities, the flow of the air curtains can be controlled by adjusting the hose, and the direction of the air curtains can be controlled by adjusting the guide vane angle adjuster. The device is composed of a main pipeline and a plurality of jet flow cavities, and is provided with a plurality of air curtain jet devices so as to meet the determination requirements of multiple angles, large area and high precision.

Description

technical field [0001] The invention relates to the technical field of downhole air curtain generation, in particular to an adjustable downhole air curtain device and its use. Background technique [0002] In recent years, with the rapid development of the country's mechanization level, the mechanization level of coal mines has also gradually increased. The large-scale use of large mining heights, fully mechanized excavation, and fully mechanized mining mechanized equipment has increased the output of coal mines. The increase in output will lead to an increase in coal mine dust. In the process of coal mining, such as fully-mechanized mining, fully-mechanized excavation, reloading, transportation, and secondary dust, etc., will cause a lot of dust. The fully-mechanized excavation face is the main dust source underground, and dust prevention and control is particularly important under narrow environmental conditions. The suppression of dust can not only reduce the particulate ...
