Dust removal equipment suitable for dust control over coal mining face

Abstract

The invention belongs to the technical field of removal of coal mine dust and provides dust removal equipment suitable for dust control over a coal mining face. The problems that a traditional dust removal method is low in dust removal efficiency, high in water consumption, high in dust prevention cost and the like are solved. The dust removal equipment suitable for dust control over the coal mining face comprises an angle steel base, a steel frame and a plurality of sets of dust removal air drums. The dust removal air drums are arranged horizontally, distributed annularly and evenly and fixed with the steel frame. The bottom of the steel frame is connected with the angle steel base. The dust removal air drums are connected through spraying pipelines. Each dust removal air drum is of a stepped structure and comprises a first-stage drum body, a second-stage drum body and a third-stage drum body, and the diameters of the first-stage drum body, the second-stage drum body and the third-stage drum body are gradually increased. The dust removal equipment can be installed on a coal mining machine and a heading machine, so that the coal mining machine and the heading machine move along with operation equipment to carry out continuous dust removal, the operation environment is improved for a driver of the coal mining machine to a great extent, and the effect of local dust removal is achieved; and compared with a traditional spraying dust removal mode, the most efficient dust removal effect can be achieved with the minimum water consumption, and the dust removal efficiency is remarkably improved.

Description

Technical field [0001] The invention belongs to the technical field of dust removal of coal mine dust, and particularly relates to a dust removal device suitable for coal mine dust control. Background technique [0002] Coal mine dust is one of the five major hazards of mines. A large amount of high-concentration dust is generated during the mining process and other processes. Modern mining technology with high-yield, high-efficiency, and low-consumption characteristics, its dust production is greatly increased compared with traditional mining technologies. Dust from underground mining work mainly comes from the crushing, loading, and support of mining machinery, followed by the reloading of transfer machines and conveyors. The dust concentration in fully mechanized caving face is generally high, and the proportion of respirable dust in the total dust is as high as about 20%. In recent years, domestic and foreign studies have shown that coal dust is not only an important cause o...
