Abstract

The invention discloses a wind-water atomizing aspirating device for mines. The wind-water atomizing aspirating device for the mines comprises an atomizer, a blade and a water pipe, the atomizer comprises a front hub and a rear hub which are fixedly connected through a bolt, a drive axle which is connected with power equipment is arranged on the rear hub, a water inlet inner cavity and an atomizing inner cavity which are communicated with each other through an aqueduct are formed in the front hub, the atomizing inner cavity is arranged on the outer side of the water inlet inner cavity and is of an annular structure, a water outlet end of the water pipe is introduced into the water inlet inner cavity, and an installation end of the blade is installed between the front hub and the rear hub through a bolt. According to the wind-water atomizing aspirating device for the mines, a hydraulic motor or an explosion-proof electric machine can be adopted to drive the wind-water atomizing aspirating device, spray is blown out through wind power produced by a wind wheel, dense fogdrops collect dust, and the purpose of aspirating is achieved; due to the fact that the atomizing device is made of special steel, more corrosive gas exists in mining areas, the corrosive gas is dissolved in water to form acid, and equipment which is used in the mining areas for a long time is prone to corrosion through acidic materials; by means of titanium alloy hubs, the defect that the corrosion is produced due to long-time soaking in the water can be effectively overcome; by means of the improvement of material components, the atomizing efficiency of the aspirating device is improved.

Description

technical field [0001] The invention relates to a dust suppression device, in particular to a wind water atomization dust suppression device for mining. Background technique [0002] Dust is one of the five natural disasters in coal mines. With the continuous improvement of the mechanization and automation level of coal mines, high-yield and high-efficiency mines have emerged, but while bringing huge economic benefits to coal mines, they have also brought serious harm. Fires and explosions caused by high dust concentration occur from time to time, causing heavy casualties. In severe cases, mines are destroyed, causing huge loss of life and property. In addition, dust is extremely harmful to human health, especially small particle size particles. Coal miners are prone to occupational pneumoconiosis when they are exposed to high-concentration dust for a long time. Therefore, it is an important task for coal mine safety to study and further solve the long-standing problem of...
