Abstract

The invention relates to composite electroless efficient special dust-removing equipment for coal mines, which has the structural characteristics that a dust-removing fan is installed in a fan chamber; the fan chamber is closely connected with an air-water separation chamber; the air-water separation chamber is connected with a sprinkling chamber; a nozzle is installed in the sprinkling chamber; a shutter is arranged between the sprinkling chamber and a filter chamber; a filter screen is arranged between the filter chamber and a dust-drying chamber; one end of a dust-collecting flexible pipe is connected with an air inlet pipe to extend into the dust-drying chamber, and the other end of the dust-collecting flexible pipe is connected with a dust-collecting cover; the bottom of the air inlet pipe of a dust collector is blocked; a big hole is formed on the lateral surface of the air inlet pipe of the dust collector; and a dust-discharging opening is arranged below the dust-drying chamber. The invention has the advantages that a specific dust-collecting cover can separate 60-70% of coal dust per se under the condition that the dust collector is not started, and the coal dust which can not be separated by the dust-collecting cover is absorbed by the electroless dust-removing equipment. In the processes of design and manufacture of the equipment, problems of electrostatic prevention, spark prevention in operation and other problems related to mine-shaft safety are fully considered. Two-stage dust removal of a dry method and a wet method is adopted in the electroless dust-removing equipment.

Description

Composite electroless efficient special dust-removing equipment for coal mines
Technical field
What the present invention relates to is the composite electroless efficient special dust-removing equipment for coal mines of a kind of colliery dedusting, belongs to safety of coal mines and environmental protection cleaner technical field.
Background technology
The dustproof operation of coal mine underground coal bed boring, every brill one hole flies out with regard to the coal dust that has nearly 1 ton of raw coal to form, and several kilometers a slices in air port are black to the greatest extent down in the tunnel, and sight is shocking.Coal dust is very harmful in the colliery, the easiest dust explosion that causes, and accident causes casualties.Also be to cause the miner to get the root of pneumoconiosis simultaneously.For these years, for ensureing the healthy of mine safety and operating personnel, constantly organizational technology's tackling key problem has designed and produced various dust arresters in the industry, but poor effect, dust removal efficiency at the most 60%
Summary of the invention
What the present invention proposed is a kind of composite electroless efficient special dust-removing equipment for coal mines that is applicable to the dustproof operation of coal mine underground coal bed boring, be intended to overcome the above-mentioned defective of existing in prior technology, from the airborne dust point, before the coal dust diffusion, it is removed, special dust shield links to each other with the coal dust clearing machine by sweep-up pipe, the on-the-spot dust removal efficiency that uses reaches 95%, and coal dust is eliminated substantially.
Technical solution of the present invention: its structure is that dedusting fan is installed in the fan house, fan house is right after air-water separation chamber, air-water separation chamber and spray chamber join, and shower nozzle is installed in the spray chamber, establish shutter between spray chamber and filter chamber, between filter chamber and dried dirt chamber filter screen is set, it is indoor that a connection of hose blast pipe stretches into dried dirt, and the other end of hose connects dust shield, the blocking-up of dust catcher blast pipe bottom, dust catcher blast pipe side has macropore, and the below of dried dirt chamber is provided with the dust discharge mouth.
Advantage of the present invention: special dust shield: this dust shield self can separate the coal dust of 60-70% under the situation that does not start vacuum cleaner.The coal dust that dust shield fails to separate is not had electric dust-removing equipment and is absorbed.This equipment has been considered all problems relevant with mine safety such as antistatic, sparkproof in service fully in the process of designing and producing.This nothing electric dust-removing equipment inner employing dry method and the dedusting of wet method two-stage.
Description of drawings
Accompanying drawing 1 is the structural representation of composite electroless efficient special dust-removing equipment for coal mines.
Among the figure 1 is dust shield, the 2nd, hose, the 3rd, dried dirt chamber, the 4th, filter screen, the 5th, dust discharge mouth, the 6th, filter chamber, the 7th, shutter, the 8th, spray chamber, the 9th, shower nozzle, the 10th, air-water separation chamber, the 11st, fan house, the 12nd, dedusting fan.
The specific embodiment
Contrast accompanying drawing 1, its structure is that dedusting fan 12 is installed in the fan house 11, fan house 11 is right after air-water separation chamber 10, air-water separation chamber 10 joins with spray chamber 8, shower nozzle 9 is installed in the spray chamber 8,6 of spray chamber 8 and filter chambers are established shutter 7, filter chamber 6 and 3 of dried dirt chambers are provided with filter screen 4,2 one of hoses connect blast pipe and stretch in the dried dirt chamber 3, the other end of hose 2 connects dust shield 1, the blocking-up of dust catcher blast pipe bottom, dust catcher blast pipe side has macropore, and the below of dried dirt chamber is provided with the dust discharge mouth.
When the workman holes, a large amount of coal dusts of ejection in the hole, and diffusion immediately, under the effect of mine ventilation air-flow, direction is stretched rapidly alee.After setting up dust shield 1, particle heavier in the coal dust just avales in dust shield, slowly spue through dust flue, do not dispelled by down-hole draft, and lighter fine grained raises up under the suction of dust removal machine and enters the dried dirt of dust removal machine chamber 3 through sweep-up pipe 2, the particle of being held back by filter screen 4 is in the chamber sedimentation of dried dirt, slowly tell on the belt conveyer through dust discharge mouth 5 and to transport, the extra fine coal dust sees through filter screen 4 and enters spray chamber 8 through shutter 7, the function of shutter is filter screen 4 to be exempted from drench, in spray chamber 8, and nozzle 9 ejection water smokes, tiny coal dust total number is caught, flow out to Mine Drainage System through water sealing (sealing water) pipe.Be about to leave in the air-flow of spray chamber and have a large amount of addle that contains coal dust, after air-water separation chamber 10 separates, addle flows into the spray chamber bottom and discharges, and the air of discharging after gas-water separation is cleaner not with water droplets air, is incorporated in the mine overall situation by blower fan 12 sucking-offs.
Blower fan 12 usefulness air motors drive, it is more safer than fire-proof motor, the outer baffle liner of draught fan impeller is an aluminium matter, in case and blade rubbing, can not produce spark, dust shield 1 also is an aluminium matter, in case with the drilling rod grazing, also can not produce spark, filter screen 4 is composite web of antistatic, thereby has stopped the danger of generation of static electricity electric spark.
This cleaner operation is fairly simple, does not have dangerously, discharges dirt equipment earlier from and holes and just can prevent that the coal dust unrest from flying as long as follow during operation.
