Problems solved by technology

[0004] The invention provides a coal mining machine dust removal device for coal mining and its dust removal method, which has the advantages of improving the dust removal effect of the coal mining machine dust removal device for coal mining and saving water costs, and solves the problem of existing coal mining. The machine dust removal device is generally installed on the rocker arm of the shearer and near the fuselage to install internal and external spraying devices, that is, to spray water to the mining area through the nozzle. However, in practical applications, it is found that the shearer still has A large amount of dust is generated, and the effect of dust removal is not ideal, and through the installation of internal and external spray devices, some coal shearers even install three-layer spray devices, but the internal structure of the nozzle has not been properly improved, so that the sprayed water mist The bead particles are larger, which in turn reduces the contact space between water droplets and dust. Even if multi-layer spray is used, the annular water curtain sprayed out is still formed by large water mist beads, which will still cause water mist beads and dust to be unable to contact. phenomenon, but also the problem of increased water costs

Abstract

The invention relates to the technical field of coal mining machine dust removal, and discloses a coal mining machine dust removal device for coal mining. The device comprises a water tank, wherein arack is arranged at the top of the water tank, the bottom of the rack is fixedly connected with the top of the water tank, a water pump is fixedly connected to the middle of the front surface of the rack, a fixing column is fixedly installed on the right side of the rack, and an air collection device is fixedly installed in the middle of the fixing column. According to the coal mining machine dustremoval device and a dust removal method thereof, through the cooperation of a rocker arm nozzle device and the air collection device, fan blades are used to absorb air out of a water curtain formedby the rocker arm nozzle device, the moisture entering a conical body is extruded, the moisture can be conveniently formed into fine water beads, and the atomization effect of nozzles of the coal mining machine dust removal device for coal mining is improved; and after the water beads are atomized, the weights of the condensed dust beads are increased, and the dust removal effect of the coal mining machine dust removal device for coal mining is improved.

Description

technical field [0001] The invention relates to the field of coal mining machine dust removal technology, in particular to a coal mining machine dust removal device and a dust removal method for coal mining. Background technique [0002] Coal mining machine is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve high output, high efficiency, and low consumption. However, with the improvement of the mechanization level of coal production, mining The intensity increases, the dust production increases, and the dust concentration in the coal mine also increases, which seriously pollutes the mine operating environment, reduces the service life and accuracy of instruments and equipment, reduces the visibility of the production site, is prone to spontaneous combustion, and causes long-term dust exposure personnel to suffer from pneumoconiosis Diseases and ...
