Abstract
The invention relates to drilling dustproof equipment for an underground coal bed of a coal mine, and the drilling dustproof equipment is structurally characterized in that a dedusting fan is mounted in a fan room; the fan room is closely connected with a gas-water separating room; the gas-water separating room is connected with a spraying room; a spray head is mounted in the spraying room; a shutter is arranged between the spraying room and a filtering room; a filtering screen is arranged between the filtering room and a dust drying room; one end of a dust sucking hose tube is connected with a gas inlet tube and stretches into the dust drying room; the other end of the dust sucking hose tube is connected with a dust sucking hood; the bottom of a gas inlet tube of a dust sucker is blocked; the side surface of the gas inlet tube of the dust sucker is provided with big holes; and dust discharging nozzles are arranged below the dust drying room. The drilling dustproof equipment for the underground coal bed of the coal mine has the advantage of comprising the special dust sucking hood, and the dust sucking hood can separate 60-70% of coal dust per se under the condition that a dust sucking machine is not started. The coal dust which cannot be separated by the dust sucking hood is absorbed by current-off dust removing equipment. By using the drilling dustproof equipment for the underground coal bed of the coal mine, all problems relevant with the safety of a mine well, such as electrostatic prevention, spark prevention in a running process, and the like, are fully considered in a design process and a manufacturing process. In the drilling dustproof equipment for the underground coal bed of the coal mine, the two-stage dust removal is carried out by adopting a dry method and a wet method.
Description
Technical field
What the present invention relates to is coal mine underground coal bed boring dust guard pollution abatement equipment, 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 tackles key problems in the industry, has designed and produced various dust arresters, but poor effect, dust removal efficiency at the most 60%.Summary of the invention
What the present invention proposed is a kind of coal mine underground coal bed boring dust guard pollution abatement equipment; Be intended to overcome the above-mentioned defective of existing in prior technology; From the airborne dust point, before the coal dust diffusion, it to be removed, special dust shield links to each other with the coal dust clearing machine through sweep-up pipe; The on-the-spot dust removal efficiency that uses reaches 95%, and coal dust is eliminated basically.
Technical solution of the present invention: its structure is that dedusting fan is installed in the fan house, and fan house is right after air-water separation chamber, and air-water separation chamber and spray chamber join; Shower nozzle is installed in the spray chamber, is established 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 absorbed by dust guard pollution abatement equipment.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 coal mine underground coal bed boring dust guard pollution abatement equipment inner employing dry method and the dedusting of wet method two-stage.
Description of drawings
Accompanying drawing l is the structural representation of coal mine underground coal bed boring dust guard pollution abatement equipment.
L among the figure is a 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 l, 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, and shower nozzle 9 is installed in the spray chamber 8, and 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; Hose 2-head connects blast pipe and stretches in the dried dirt chamber 3, and the other end of hose 2 connects dust shield l, 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 l, particle heavier in the coal dust just avales in dust shield, slowly spues through dust flue; Do not dispelled by down-hole draft, and lighter fine grained raises up under the suction of dust removal machine and gets into the dried dirt of dust removal machines 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 gets into spray chambers 8 through shutter 7, and the function of shutter is filter screen 4 to be exempted from drench; In spray chamber 8; Nozzle 9 ejection water smokes are caught tiny coal dust total number, 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 after gas-water separation, discharging is cleaner not with water droplets air, is incorporated in the mine overall situation by blower fan 12 sucking-offs.
This coal mine underground coal bed boring dust guard pollution abatement equipment operation is fairly simple, does not have dangerously, discharges dirt equipment earlier from and holes and just can prevent that coal dust is random and fly as long as follow during operation.
