The invention discloses a de-dusting device used for coal mine safety. The device comprises a main body and a recycling mechanism. Two sides at the upper end inside the main body are respectively andfixedly equipped with a first installation box and a second installation box. The inside of the first installation box is movably equipped with a first screw rod through a bearing. The outside of thefirst screw rod is movably equipped with a first movable part through a screw thread. Movable connection is achieved between the first movable part and the first installation box. The lower end of thefirst movable part is fixedly equipped with a first motor through an installation seat. An output shaft end of the first motor is fixedly provided with a first installation plate. The lower end of the first installation plate is fixedly equipped with a first annular nozzle. One side of the first installation box is fixedly equipped with a second motor through the installation seat. An output shaft end of the second motor is fixedly connected with a rotary rod of the first screw rod. The purpose of saving water is fulfilled by water recycling. The output cost of water utilization is reduced. Meanwhile, the purpose of secondary dedusting is obtained.
Description
technical field [0001] The invention relates to the field of dust removal devices, in particular to a dust removal device for coal mine safety. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines include large areas above and below ground and associated facilities. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usually including roadways, shafts,...
