Water mist dust falling device for coal mine

Abstract

The invention discloses a water mist dust falling device for a coal mine. The device comprises a shell, a supporting rod, walking wheels, a fixed rod, a guide shell, a collecting shell, a fixed frame,a motor, fan blades, a vertical rod, a transverse rod, a first limiting rod, a limiting plate, a second limiting rod, a mounting plate, a first water distribution pipe, a second water conveying pipe,a vertical plate, a second water distribution pipe, an inclined pipe, a transverse pipe, a nozzle, a transmission rod, a water tank, a high-pressure water pump, a five-way pipe, a first water conveying pipe, a mounting rod, a top plate, a dust shield, a bottom plate and a dirt storage shell. An air draft dust falling mechanism located on the shell can suck water mist water drops with dust in theair around the device into the dirt storage shell in the shell, the whole water mist dust falling process is accelerated, and the device is particularly suitable for areas, needing rapid dust falling,in a coal frame. Omnibearing dust falling is conducted on the space to be subjected to dust falling through the primary dust falling mechanism and the secondary dust falling mechanism, and the dust falling area is large; meanwhile, the two dust falling mechanisms are distributed in a high-low gradient mode, and the concentration of water mist in the space is increased.

Description

technical field [0001] The invention relates to a dust suppression device, in particular to a water mist dust suppression device for coal mines, and belongs to the technical field of application of coal mine dust suppression equipment. Background technique [0002] Coal mine dust is the general term for all kinds of fine particles of solid matter produced in the coal mine production process. The dust suspended in the air is called floating dust, also known as floating dust; Dust is called falling dust, also known as deposited dust. Floating dust enters the human respiratory organs with human breathing, and the larger dust particles are blocked in the respiratory tract and are easy to be excreted, while most of the dust with a particle size of less than 5 microns can enter. Human lungs cause various types of pneumoconiosis. Generally, such dust is called respirable dust, and dust with various particle sizes suspended in the air is called whole dust. The pneumoconiosis caused...

Problems solved by technology

[0003] Therefore, in order to ensure the safety of the workers working in coal mines, coal mines will install equipment for dust reduction, among which water mist dust reduction is a relatively common one. Water mist dust reduction is to pressurize water and spray it out from the nozzle to form water mist. After the fog is formed, it diffuses into the air, and the water mist contacts and fuses with the floating dust in the air to form larger water droplets and then fall to realize the dust reduction function. Natural fall under gravity, low efficiency, when a certain area needs to quickly reduce dust, traditional equipment is difficult to meet
