Description
Technical field
The present invention relates to drilling project field, particularly a kind of drilling project blowout prevention, device for reducing dust.
Background technology
In actual drilling construction process, due to the ore deposit complex geologic conditions, gas permeability of coal seam is low, wear hierachy number many in the drilling construction process, extraction drilling construction difficulty is larger, and crown drill in the process of drilling, bit freezing, spray orifice phenomenon happen occasionally, and has a strong impact on the construction of extraction boring, sometimes the high concentration gas that in the hole, spray orifice moment gushes out easily causes the gas exceeding limit accident; In work progress, adopt wind-force row powder, bring a large amount of coal dusts to fly upward outside the aperture, dust floats in the tunnel several meters even tens meters, severe exacerbation working environment, and be mingled with coal cinder in the dust that returns out and dishing out pressing under the wind effect, field operation personnel personal safety is subject in various degree threat, be directly connected to worker's physical and mental health, and become a large hidden danger of safety in production; When adopting the clear water deslagging, owing to taking out the lane and generally all be in coal seam floor lower 20 meters left and right in the end, to pass 3-4 layer coal and seam (82,73,72 coal and seam) in the construction drill process, easily cause way of escape coal seam section collapse hole, cause cinder to stop up the way of escape, thereby cause embracing the brill phenomenon, the drilling construction difficulty is large, has a strong impact on the probing drilling depth, so on-the-spot at drilling construction, the development dust guard, extremely urgent.
Summary of the invention
In order to overcome the above problems, this practicality provide a kind of prevent in extraction drilling construction process spray orifice cause gas exceeding limit and coal dust harm worker healthy, improve the safety factor in drilling machine construction, and reduce to greatest extent coal dust to the pollution in tunnel, utilize the dust guard of existing waste and scrap.
The present invention is achieved through the following technical solutions: a kind of drilling project blowout prevention, device for reducing dust, comprise long tube, reach the short tube that welds together with long tube, and be arranged on the drilling rod entrance of long tube and short tube joint, reach and coordinate the method wheel disc one of installing with the drilling rod entrance, and be arranged on sealing ring on method wheel disc one, and the method wheel disc two that is connected with the short tube lower end, and be arranged on sleeve pipe in method wheel disc two, and the flexible pipe that is connected with sleeve pipe, and being arranged on the fog-spray nozzle of short tube both sides, the size of described sealing ring is identical with method wheel disc one.
Further, have four screw eyes that match with method wheel disc one on described sealing ring, and be distributed on the circumference of sealing ring; Have a hole that matches with drilling rod in the middle of described sealing ring.
Further, become 50 °～55 ° angles between described long tube and short tube.
Further, the fog-spray nozzle of described short tube both sides respectively has 3, and with short tube angle at 45 °, fog-spray nozzle is installed down, the welding of staggering of the fog-spray nozzle of both sides.
Beneficial effect of the present invention have following some:
1, security performance improves greatly.By using dust guard, can reduce to greatest extent the gas of release during drilling to the threat of site operation, stop tunnel way of escape gas exceeding limit phenomenon; The gas that utilizes this device to make to discharge in boring is down to the 0.14%-0.20% left and right by original 4%-5%, has increased staff's safety factor.
2, improved the integrated dust-removing rate.Spray by use, effectively controlled coal dust and flown upward, purified the operation place, can improve to the utmost the air ambient at bore operation scene, reduced the health harm to the workman, guaranteed workman's physical and mental health.
3, improved operating efficiency.Adopt the construction of pressure wind to join this device and stopped the influence time that way of escape collapse hole, armful brill, spray orifice are stopped work.
4, reduce investment, increased benefit.Utilize waste material processing one cover dust guard cost lower, greatly reduced the fund of purchase of equipment.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of drilling project blowout prevention of the present invention, device for reducing dust.
The specific embodiment
As shown in Figure 1, a kind of drilling project blowout prevention of the present invention, device for reducing dust, comprise long tube 10, reach the short tube 4 that welds together with long tube 10, and be arranged on the drilling rod entrance 9 of long tube 10 and short tube 4 joints, reach and coordinate the method wheel disc 1 of installing with drilling rod entrance 9, and be arranged on sealing ring 3 on method wheel disc 1, and the method wheel disc 27 that is connected with short tube 4 lower ends, and be arranged on sleeve pipe 6 in method wheel disc 27, reach the flexible pipe 5 that is connected with sleeve pipe 6, and be arranged on the fog-spray nozzle 8 of short tube 4 both sides, the size of described sealing ring 3 is identical with method wheel disc 1.
Have four screw eyes that match with method wheel disc 1 on described sealing ring 3, and be distributed on the circumference of sealing ring 3; Have a hole that matches with drilling rod in the middle of described sealing ring 3, can cut the aperture, hole according to what the drill pipe diameter of using was determined sealing ring 3 centres.
Become 50 °～55 ° angles between described long tube 10 and short tube 4, so that the boring of applicable different angle is constructed.
The fog-spray nozzle 8 of described short tube 4 both sides respectively has 3, and with short tube 4 angle at 45 °, fog-spray nozzle 8 is installed down, and the welding of staggering of the fog-spray nozzle 8 of both sides is after opening fog-spray nozzle 8, during drilling machine construction, the coal petrography powder that returns out in holing can be to greatest extent played in device inside the dirt effect of going out, stopped coal dust and pressed the wind large tracts of land to blow out behind the hole in effect of intraparticle diffusion tunnel, tunnel sanitation of environment, cause coal dust to gather, cause dust explosion accident, also the gas that discharges in the hole is played diluting effect simultaneously.
Beneficial effect of the present invention have following some:
