Dust falling device for dumping in coal mine area

Abstract

The invention discloses a dust falling device used during dumping of a coal mine area. The dust falling device comprises a dust fall shed, a dust falling channel is formed in the dust falling shed ina left-right penetrating mode. A transfer vehicle pours down ores in the dust falling channel; a dust falling device is arranged in the dust falling channel; the dust falling device comprises a hanging block fixedly arranged on the upper wall of the dust falling channel; a swing arm is rotatably arranged at the lower end of the hanging block; a blower box is arranged below the swing arm; a swinging device is arranged on the right side of the dust falling device; a water supplementing device is arranged above the dust falling shed; according to the invention, the diffusion of smoke dust can bequickly and effectively reduced; water is converted into water mist through ultrasonic waves, the water mist is sprayed out for dust falling, compared with traditional direct water flow spraying for dust falling, more effective dust falling is achieved, more water is saved, meanwhile, the effective dust falling area is larger through reciprocating swing of the spray head, the dust falling speed ishigher, water can be automatically supplemented or stopped according to the water level in the water tank, and the automation degree of dust falling is greatly improved.

Description

technical field [0001] The invention relates to the technical field of coal mine dust suppression equipment, in particular to a dust suppression device used for dumping in coal mine areas. Background technique [0002] Because the mining area will inevitably cause a lot of smoke and dust when it is dumped, it will not only cause serious pollution to the air quality, but also a huge damage to the health of the workers in the mining area, and even cause occupational diseases and illness. The traditional way of dust suppression is to use water Jetting to the dust to achieve the purpose of dust reduction, the dust reduction efficiency is low, the dust reduction area is small and the speed is slow, and the water consumption is large, which seriously wastes water resources. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] technical problem: [0004] The traditional way of dust reduction is to spray w...
