Cloud dust-removal device for metal mine roadway

Abstract

The invention discloses a cloud dust-removal device for a metal mine roadway, including a steel frame structure, ultrasonic atomization nozzles, an inclined strut, a steel bottom plate, a water drainage diverter arranged on the steel bottom plate, a precise water filtering device, an air pressure gauge and a regulating valve thereof, a water flowmeter and a regulating valve thereof, and an air exhaust diverter. The steel frame structure is fixedly connected to the steel bottom plate. One end of the inclined strut is fixedly connected with the steel frame structure, and the other end is fixedlyconnected with the steel bottom plate. The steel frame structure is a gantry frame and is made of U-shaped steel, the opening direction of the U-shaped steel is the same as the air flow direction, the ultrasonic atomization nozzles are fixed to the front side and the left side and the right side of the U-shaped steel, the spraying angle is 80 degrees, the ultrasonic atomization nozzles on the front side directly face the air flow direction for spraying, and the ultrasonic atomization nozzles on the left side and the right side are staggered. By arranging the ultrasonic atomization nozzles with the spraying angle of 80 degrees, the whole roadway section can be filled with dry fog, the contact area between the dry fog and dust particles is fully increased, the dust removal effect is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of dust removal in metal mine roadways, in particular to a cloud and mist dust removal device used in metal mine roadways. Background technique [0002] In recent years, with the increase in the amount of underground mining in metal mines, the increase in investment in equipment and personnel, and the application of advanced production technologies, a large amount of dust has followed. Due to the unreasonable design of the underground ventilation system or poor ventilation management, a large amount of high-concentration dust will be enriched in underground stopes, roadways and other operating areas, which not only seriously affects the physical and mental health of on-site workers, threatens the mining safety of underground mines, and seriously Pollution of the underground and surface environment. [0003] According to incomplete statistics, 75%-85% of the dust in metal mines is distributed in roadway-type...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a cloud and mist dust removal device for metal mine roadway, which solves the problem that the dust removal device in the prior art occupies a large space, has a complex structure, is too heavy, and has poor mobility, and the dust removal device is difficult to operate underground and not easy to operate. Ease of daily management, etc.
