Dust removing sprayer for mine

Abstract

The invention discloses a dust removing sprayer for a mine, which comprises a shell. The shell is provided with a suspender used for suspending the whole dust removing sprayer for the mine; a distributor is arranged in the shell; one end of a header water inlet pipe is connected with a water inlet end of a water flow distribution passage in the distributor, and the other end of the header water inlet pipe is extended out of the shell and connected with a water source; one end of the header water inlet pipe is communicated with an air inlet end of a compressed air distribution passage in the distributor, and the other end of the header water inlet pipe is extended out of the shell and connected with a compressed air source; a plurality of ends are communicated with a water distribution endof the water flow distribution passage in the distributor, and the other ends are extended to a nozzle outside the shell; and the nozzle is provided with an air inlet connector which is communicated with the compressed air distribution passage of the distributor through an air distribution pipe. The sprayer can achieve good application effect of reducing the dust by adopting the mass transfer of fog droplets under high-speed airflow acceleration, has the advantages of gas consumption economization, little used water, fine and even fog droplets, large diffusion area, no spraying dead angle, safety, and explosion prevention, and is suitable for continuous operation under severe environment.

Description

technical field [0001] The invention relates to a fog-making and spraying device, in particular to a dust-removing sprayer for mines. Background technique [0002] Coal dust is one of the five natural disasters in mines, and it endangers the health of miners every moment. In serious cases, it will take people's lives. At present, the known dust-proof facilities at the reloading point of coal mine conveyors adopt two methods. One is to manually open and close the valve to control the water source to form a spray, which is inconvenient to operate and is greatly affected by human factors. Frequent switching is likely to cause damage to the valve; the other is to use Electric control, but its control circuit is complicated, the equipment is heavy, installation and maintenance are difficult, and it also brings safety hazards, which requires explosion-proof treatment. In addition, the humidity of the fog sprayed by the current sprayer is too high, which will easily affect the qu...

At present, the known dust-proof facilities at the reloading point of coal mine conveyors adopt two methods. One is to manually open and close the valve to control the water source to form a spray, which is inconvenient to operate and is greatly affected by human factors. Frequent switching is likely to cause damage to the valve; the other is to use Electric control, but its control circuit is complicated, the equipment is heavy, installation and maintenance are difficult, and it also brings potential safety hazards, which requires explosion-proof treatment

In addition, the humidity of the fog sprayed by the current sprayer is too high, which will easily affect the quality of coal mines.
