Pneumatic hydrodynamic linkage spray dust reduction device for blasting working face

Abstract

The invention discloses a pneumatic hydrodynamic linkage spray dust reduction device for blasting a working face. The device comprises a water pipe connected with a purified water curtain device, a water pipe is transversely fixedly connected to a bracket, a vertically arranged connecting rod is hingedly connected with the lower portion of the free end of the bracket by a rotating shaft, the connecting rod is provided with a hook, and an iron plate is arranged at the lower end of the connecting rod; a quick valve is installed on the water pipe below the bracket, a valve stem of the quick valveand a transversely arranged rotating rod are linked, the rotating rod passes through the hook and is positioned by the hook, and a heavy hammer is hanged on the free end of the rotating rod; the lower end of the water pipe is connected with an air inlet pipe and a water inlet pipe through a Y-shaped triplet, and regulating valves are respectively arranged at the ends of the air inlet pipe and thewater inlet pipe. The device can greatly improve the on-site working environment, ensure the health of personnel, and have simple device manufacturing, easy material obtaining and good economic benefits.

Description

Technical field [0001] The invention relates to a wind and water linkage spray dust suppression device for blasting working faces. Background technique [0002] The blasting process in the production process of underground mines is one of the main sources of dust, which has an adverse effect on the on-site operating environment and personnel health. At present, most of the dust reduction measures on the blasting face are water spraying or spraying in the tunnel before and after the blasting. During the blasting, there is basically no dust control, or Use the purchased automatic spray device. Due to the high humidity and dust in the underground mine site, and there are many flying rocks and large vibrations when the working face is blasted, the sensors and electronic control devices of the automatic spray dust suppression devices on the market have a high failure rate in the above environment, and each set of automatic The purchase and maintenance costs of spray dust suppression ...

Problems solved by technology

[0002] The blasting link in the production process of underground mines is one of the main sources of dust, which has adverse effects on the on-site operating environment and the health of personnel. At present, the dust suppression measures on the blasting working face are mostly watering or spraying dust in the roadway before and after the blasting. There is basically no dust control during the blasting period, or Use purchased automatic spraying device

Due to the high humidity and dust in the environment of the underground mine site, and there are many flying rocks and large vibrations during the blasting of the working face, the sensors and electronic control devices of the automatic spray dust suppression devices on the market have a high failure rate in the above-mentioned environment, and each set of automatic Spray dust suppression device purchase and maintenance costs are relatively high
