By using the dust remover for the automatic deslagging hole, dust can be removed from a drilling hole and gas can be prevented from spraying out; the air environment in a drilling operation site is improved; and moreover, slag can be discharged automatically, and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of mining orifice dust catcher, specifically be the automatic discharge orifice dust catcher.
Background technology
At present, the colliery highly gassy mine has all been installed gas pumping station, and in use the gas discharge in mine pipeline can accumulate big water gaging and cinder, causes pipeline blockage, has reduced gas drainage under suction efficient.So coal mine gas negative pressure extraction pipeline has been installed a large amount of automatic tailraces of gas drainage under suction pipeline.
The function but the automatic tailrace of gas drainage under suction pipeline of coal mine gas negative pressure extraction pipeline installation at present only discharges water can not be carried out dedusting and prevent the gas ejection hell.
The utility model content
The utility model technical problem to be solved provides a kind of automatic discharge orifice dust catcher, can carry out dedusting and prevent gas ejection hell, improves the on-the-spot air ambient of bore operation, and can automatic discharge, increases work efficiency.
The utility model is that the technical scheme that the deficiency that solves the problems of the technologies described above adopts is: the automatic discharge orifice dust catcher; Be made up of dedusting jet pipe, cyclone separator, gas drainage under suction pipeline, negative pressure tailrace, dust arrester and balance pipe, cyclone separator upper end is communicated with an end of gas drainage under suction pipeline, and the dedusting jet pipe is and is horizontally disposed with; The one of which end is provided with slag inlet; Slag inlet and dust arrester, the other end is communicated with cyclone separator, is provided with high pressure nozzle in the dedusting jet pipe; The slag-drip opening of cyclone separator bottom is arranged in the negative pressure tailrace, and the slag-drip opening place is provided with one way valve;
The lower end of described negative pressure tailrace is provided with the deslagging dewatering outlet; The upper end of negative pressure tailrace is provided with breather valve; The upper end of negative pressure tailrace is through balance pipe and gas drainage under suction pipeline connection, and the top inner surface of negative pressure tailrace is provided with the magnet I, is fixed with a fixed bar on the bottom surface of negative pressure tailrace inside; Be with ball float on the fixed bar; Above ball float, be provided with pallet, tray upper surface is provided with side direction guide peg and the magnet II that is complementary with breather valve, and an end of side direction guide peg is arranged in the breather valve.
The beneficial effect of the utility model is:
1, can the dust that when boring discharges be removed, and discharge through the slag-draining device that discharges water, when the methane gas ejection appearred in boring, methane gas can be transported to ground through the gas drainage under suction device, has avoided the operation field gas exceeding limit.This device dedusting is easy to use, and water consumption is few.Can greatly improve the on-the-spot air ambient of bore operation, help the operator physical and mental health, increase work efficiency.
2, atmospheric pressure capable of using and buoyancy carry out the automatic discharge draining, need not manual operation, reduce the manpower work.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1, high pressure nozzle, 2, the dedusting jet pipe, 3, cyclone separator, 4, the gas drainage under suction pipeline, 5, slag inlet; 6, slag-drip opening, 7, one way valve, 8, the negative pressure tailrace, 9, the deslagging dewatering outlet, 10, ball float; 11, pallet, 12, the magnet I, 13, the side direction guide peg, 14, balance pipe; 15, breather valve, 16, fixed bar, 17, the magnet II, 18, dust arrester.
The specific embodiment
As shown in the figure, the automatic discharge orifice dust catcher is made up of dedusting jet pipe 2, cyclone separator 3, gas drainage under suction pipeline 4, negative pressure tailrace 8, dust arrester 18 and balance pipe 14; Cyclone separator 3 upper ends are communicated with an end of gas drainage under suction pipeline 4; Dedusting jet pipe 2 is and is horizontally disposed with, and the one of which end is provided with slag inlet 5, slag inlet 5 and dust arrester 18; The other end is communicated with cyclone separator 3; Be provided with high pressure nozzle 1 in the dedusting jet pipe 2, the slag-drip opening 6 of cyclone separator 3 bottoms is arranged in the negative pressure tailrace 8, and slag-drip opening 6 places are provided with one way valve 7;
The lower end of described negative pressure tailrace 8 is provided with deslagging dewatering outlet 9; The upper end of negative pressure tailrace 8 is provided with breather valve 15; The upper end of negative pressure tailrace 8 is communicated with gas drainage under suction pipeline 4 through balance pipe 14, and the top inner surface of negative pressure tailrace 8 is provided with magnet I 12, is fixed with a fixed bar 16 on the bottom surface of negative pressure tailrace 8 inside; Be with ball float on the fixed bar 16; Above ball float 10, be provided with pallet 11, pallet 11 upper surfaces are provided with the side direction guide peg 13 and magnet II 17 that is complementary with breather valve 12, and an end of side direction guide peg 13 is arranged in the breather valve 12.
The water jet that utilizes high velocity jet forms negative pressure in the jet pipe zone, and then produces distinguished and admirablely, and distinguished and admirable drive coal dust tangentially gets into cyclone separator by import; Carry out top-down rotatablely moving; Water and coal dust particle fall in the rotation of cyclone separator inwall under rotary centrifugal force, inertia force and action of gravity, discharge through slag-drip opening, through one way valve moisture cinder are entered the negative pressure tailrace; Get into the negative pressure tailrace through one way valve, reach dust removing effects.Along with increasing of slag in the bucket and ponding, treat that grain slag rises to when being enough to float, ball float also will rise thereupon.When rising to certain altitude, the magnet of pallet and the following unexpected adhesive of magnet of tailrace lid, the sealing offset plate on the pallet is dead with the negative-pressure balancing pipe plug at this moment, and the side direction guide peg backs down atmospheric valve.Because bucket is interior and atmosphere, the water inlet unidirectional stop valve closes half.Make barrel external and internal pressure equate that under the hydrostatic pressure effect of slag and ponding, slag-drip opening is opened because air gets into tailrace, the slag that begins to set a raft going discharges water, thereby reaches the effect of dedusting.When the methane gas ejection appearred in boring, methane gas can be transported to ground through the gas drainage under suction device, has avoided the operation field gas exceeding limit.
This device is easy to use, water consumption is few, can greatly improve the on-the-spot air ambient of bore operation, help the operator physical and mental health, increase work efficiency.
