Ventilation and dust removal device for coal mine operation

Abstract

The invention provides a ventilation and dust removal device for coal mine operation. The ventilation and dust removal device comprises a dust collecting cylinder, a second collecting bucket and a dust collecting cloth bag. A supporting frame is welded at the position below the outer wall of the dust collecting cylinder, and the bottom end face of the dust collecting cylinder is fixedly connectedwith a dust collecting bucket through a bolt. A first collecting bucket and the second collecting bucket are sequentially welded to the bottom end face of an air inlet pipe from left to right. Throughcooperative arrangement of a sliding seat and a dedusting brush, on the one hand, through the rotation of a dust collecting cylinder main body, the dedusting brush can sweep dust on the outer surfaceof the dust collecting cloth bag, which can firstly serve as another mode of cleaning the dust collecting cloth bag besides blowing cleaning and can secondly prolong the continuous use time of the dust collecting cloth bag and reduces the time of dismantling and cleaning to some extent, and on the other hand, due to a sliding connection relationship between the sliding seat and the dedusting brush, the dedusting brush can be dismantled for cleaning during the refined cleaning.

Description

technical field [0001] The invention belongs to the technical field of ventilation and dust removal equipment, and more specifically relates to ventilation and dust removal equipment for coal mine operations. Background technique [0002] With the continuous increase of the overall mining scale, mining intensity and mining depth of mines, especially the old mines whose mining capacity has been improved through renovation, expansion and construction, the mine ventilation system network is complicated, the ventilation network structure is unreasonable, the ventilation air path is long, and the ventilation resistance Difficult to manage daily ventilation. At present, one of the important ways to effectively solve the difficulty of mine ventilation is to use the existing shaft engineering as the air intake shaft (lane) or ventilation air path, but this approach faces the problem of air purification and dust removal. Although the dust removal technology and engineering technolog...
