Mining dedusting device having dust-reducing and adsorbing functions

Abstract

The invention discloses a mining dedusting device having dust-reducing and adsorbing functions. The mining dedusting device comprises a dedusting box. Wheels are arranged at the bottom of the dedusting box, a filtering water tank is arranged at the bottom in the dedusting box, drainage pipes are arranged on two sides of the bottom of the filtering water tank, a secondary filter net is fixed at thetop of the filtering water tank, water incoming pipes are arranged above two sides of the secondary filter net, filtering water incoming joints are fixed on two side walls of the dedusting box, an exhaust pipe is arranged in the filtering water tank, a dust absorbing air pump is fixed on the top face of an air pump base, a water drainage end of the dust absorbing air pump is connected with a primary filter box, a dust absorbing port is arranged at the top end of a dust absorbing pipe, a cleaning door and exhaust holes are arranged on a rear side plate of the dedusting box, multiple water nozzles are arranged on the side wall of the dedusting box, and a water pump is fixed on the top face of a water spraying tank which is fixed on the inner side wall of the dedusting box. A double mode ofsuction filtering and spray dedusting is utilized for dedusting, so that dedusting efficiency is improved greatly, and the primary filter net plays a great role in denoising.

Description

technical field [0001] The invention relates to the field of mining auxiliary equipment, in particular to a mining dust removal device for dust reduction and adsorption. Background technique [0002] In the process of mining operations, due to mechanical and manual construction, there will be relatively large dust. If it cannot be removed in time, it will cause great harm to the body of the workers, and the floating smoke and dust will have a great impact on the air quality. General dust suppression usually There are two ways, one is to spray mist water directly in the air to absorb the dust in the air, and accelerate the condensation and fall of dust; The dust is filtered by suction and filtration. The first method has a slower dust reduction effect and will cause the surrounding environment to be humid. The second method has a faster dust removal effect, but generally uses fixed suction and exhaust settings, and can only be sucked at a fixed position. Dust, the use is not...

[0002] In the process of mining operations, due to mechanical and manual construction, there will be relatively large dust. If it cannot be removed in time, it will cause great harm to the body of the workers, and the floating smoke and dust will have a great impact on the air quality. General dust suppression usually There are two ways, one is to spray mist water directly in the air to absorb the dust in the air, and accelerate the condensation and fall of dust; The dust is filtered by suction and filtration. The first method has a slower dust reduction effect and will cause the surrounding environment to be humid. The second method has a faster dust removal effect, but generally uses fixed suction and exhaust settings, and can only be sucked at a fixed position. Dust, the use is not flexible, it is not very suitable for the mining dust removal process that changes frequently on the mining surface, and due to the huge friction between the dust and the fan blades of the exhaust fan, the noise of the fan is huge. If this method is used for dust removal in the mining area, For mining tunnels that are usually narrow and narrow, the noise will be very loud, which will greatly affect the normal operation of the miners

[0003] At present, the dust removal devices for mining in the market generally have the problem of excessive noise, and the dust removal process will stir the surrounding air, causing the dust to rise again, resulting in the phenomenon of dust dancing at the dust removal site, which greatly affects the health of the operator.
