Description

Technical Field

[0001] The utility model relates to a mine dust prevention spray device, belonging to the field of mine dust reduction. Background Art

[0002] During the mining process, there is a lot of dust in the tunnel. A spray pipe is usually installed on the top of the tunnel. The spray pipe is connected to the pressure water pipe in the tunnel through a connecting pipe. After opening the valve between the pressure water pipe and the spray pipe, the pressurized water in the pressure water pipe enters the spray pipe, and then the pressurized water is sprayed out through the atomizing nozzle on the spray pipe. Because the water pressure in the pressure water pipe is constant and the spray pipe is installed on the top of the tunnel, the water mist cannot diffuse to the lower space of the tunnel, resulting in poor dust reduction effect. Therefore, it is necessary to design a mine dust prevention spray device that can diffuse water mist in the entire tunnel end face. Utility Model Content
