Ventilating and dedusting device for underground coal mining

Abstract

The invention discloses ventilating and dedusting equipment for underground coal mining. The ventilating and dedusting equipment comprises a tubular hollow shell, wherein an air entering space is arranged at the inner part of the bottom part of the tubular hollow shell; multiple main air inlet pipelines in an integrated structure with the tubular hollow shell are arranged at the bottom part of thetubular hollow shell; main air inlet holes for communicating the exterior with the air entering space are formed in the main air inlet pipelines; an air filter mechanism is arranged at the inner partof the tubular hollow shell and is located above the air entering space; a main air vent for communicating the top part of the air entering space with the top part of the air filter mechanism is formed in the tubular hollow shell. The ventilating and dedusting equipment disclosed by the invention is used for air exhausting during underground coal mining, can be placed in a safety zone and can work through a pipeline; in addition, the ventilating and dedusting equipment is capable of filtering exhausted air through liquid water, so that the content of flammable matters in air can be effectively reduced; in addition, the ventilating and dedusting equipment is provided with a turbo charging mechanism, so that the air suction power can be increased.

Description

technical field [0001] The invention relates to the technical field of underground coal mining, in particular to ventilation and dust removal equipment for underground coal mining. Background technique [0002] At present, because the ventilation and dust removal equipment for underground coal mining is set up in a space with a lot of dust, and for places with combustible gas, the dust removal equipment in the form of electricity is the most dangerous. In addition, these coal mining use Most ventilation and dust removal equipment can only remove dust from one part, which has certain limitations. Contents of the invention [0003] The object of the present invention is to provide a ventilation and dust removal equipment for underground coal mining, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a ventilation and dust removal equ...
