Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a dust-proof spray device used underground in coal mines. Background Art

[0002] The dust-proof spray device for underground coal mines refers to a device installed in the underground working environment of coal mines. Its function is to reduce the diffusion and sedimentation of coal dust by spraying water mist or chemical liquids and other substances into the air, thereby protecting the health of miners and improving the working environment. The dust-proof spray device for underground coal mines usually includes nozzles, piping systems, water pumps, control systems and other components. These devices are designed to effectively reduce the concentration of coal dust in the air, reduce the possibility of miners inhaling coal dust, and protect the health of miners. Specifically, the dust-proof spray device can spray fine water mist particles into the air, so that the coal dust particles combine with the water mist particles and settle, thereby achieving the effect of dust reduction. This device is widely used in underground working faces of coal mines, around equipment such as coal mining machines and conveyors, and in ventilation tunnels and other areas. It is one of the important equipment for coal mine safety production and environmental protection. At present, dust-proof spray devices usually use nozzles to atomize water before dust reduction treatment when in use. Existing nozzles can usually only atomize water, and there is no device installed to facilitate nozzle replacement. After long-term use, the nozzles will be clogged with dust, and the entire dust reduction device needs to be replaced, which increases the cost. In addition, the spray angle of existing dust reduction devices is usually fixed when in use, and the actual spray range is limited. It is impossible to evenly suppress and reduce dust in the tunnel. There are dead angles in the spray, which can easily cause some dust to float, reducing the practicality of the dust-proof device. Utility Model Content
