Mine Machinery Automatic Opening and Closing Sprinkler Sprinkler Dust Reduction Device

Abstract

The invention provides a mining mechanical automatic opening-closing type mist-spray water-sprinkle dust-falling device which comprises a water tank, a water feeding valve, a floater, a water discharging valve and a shock wave induction unit. The water tank is provided with an upper cover which is provided with a water inflow pipe connected with a water feeding pipeline and a water outflow pipe connected with a mist spray head. The water feeding valve is arranged in the water tank and fixedly mounted on the upper cover, provided with a water feeding water inlet communicating with the water inflow pipe, further provided with a first water feeding water outlet and a second water feeding water outlet communicating with the water outflow pipe and the water tank correspondingly and used for controlling water feeding towards the mist spray head and the water tank. The floater is arranged in the water tank, located below the water feeding valve and used for controlling opening or closing of the water feeding valve. The water discharging valve is fixedly arranged on the bottom wall of the water tank, provided with a water discharging water inlet and a water discharging water outflow hole which communicate with the water tank and used for discharging water in the water tank. The shock wave induction unit is arranged at the bottom end of the water tank and used for inducting shock waves generated in down-hole blasting and generating actions to enable the water discharging valve to be opened or closed. The mining mechanical automatic opening-closing type mist-spray water-sprinkle dust-falling device is simple in structure, safe and reliable and achieves the mist-spray water-sprinkle dust-falling automatic opening-closing function.

Description

technical field [0001] The invention relates to the field of explosion-proof machinery and electrical appliances for mines, in particular to an automatic opening and closing type spraying water sprinkler and dust suppression device for mine machinery. Background technique [0002] During the mining process of underground coal, various particles—dust such as coal dust and rock dust are produced during the drilling, cutting, loading, coal dropping, blasting and transportation of the mine. Dust is a solid particle that can float in the air. Due to the special properties of dust, the size of the particle size and other factors, it is very harmful to the human body. The chemical properties of dust participate in and interfere with the degree and speed of biochemical processes in the body to varying degrees. For example, highly toxic metal dust (metal, manganese, cadmium, lead, etc.) enters the human body, causing poisoning and even death. General dust, such as silicon, asbestos,...
