Coal mine underground multi-stage energy-saving roadway cleaning device

Abstract

The invention discloses a coal mine underground multi-stage energy-saving roadway cleaning device. The cleaning device is characterized in that a water supply pipe is arranged in the longitudinal direction of a roadway, penetrates through the whole roadway and is hung on anchor rods on a roadway roof through hooks; an adjustable high-pressure water pump supplies water to the water pipe; rotary sprayer assemblies are connected with the water supply pipe in parallel through needle valves at equal intervals; each rotary sprayer assembly comprises a center nozzle and four peripheral nozzles, wherein the four peripheral nozzles each comprise a wide-angle sector-shaped atomizing nozzle and a narrow-angle sector-shaped atomizing nozzle; the number of flushing stages of the roadway is determined according to the length of the roadway through the technical means such as control switches of pneumatic actuators arranged at the height positions capable of being reached by the hands of operators, and the whole roadway is cleaned and flushed in a graded mode. Compared with the prior art, the cleaning device has the advantages of being simple in structure, convenient to control and adjust, good in dust removal and dust fall effect, low in operating cost, capable of saving energy and water, safe, stable, reliable and the like.

Description

technical field [0001] The invention relates to a mine underground roadway cleaning device, in particular to a coal mine underground multi-stage energy-saving roadway cleaning device. Background technique [0002] During coal mining, mine dust is one of the five major disasters in coal mines. [0003] Dust not only has the potential danger of explosion, but also reduces the service life and precision of equipment, reduces the visibility of the production site, and greatly increases the risk of occupational diseases (such as pneumoconiosis) for workers who have been in contact with dust sources for a long time. [0004] In the coal production process, almost all operations may generate dust. Especially for high-yield and high-efficiency mining production processes with a high degree of mechanization, the dust in the air at the downhole operating point is always maintained at a relatively high concentration. [0005] In the process of coal mining, the underground roadway is ...

Problems solved by technology

Disadvantages, all sections cannot be cleaned; if automatic control equipment is used for intelligent control, electromagnetic switches need to be installed at each point, and there are many power lines and communication lines, which are prone to failure under specific working conditions underground
