Abstract
The utility model discloses a coal seam pumping and releasing drilling negative pressure dedusting system, comprising a dedusting shield, a pumping and releasing branch pipe, a first level dedusting box and a second level dedusting box; the first level dedusting box and the second level dedusting box are connected by a flange plate; steel wire soft rubber pipe joints are arranged at the upper ends of the corresponding sides of the first level dedusting box and the second level dedusting box; the first level dedusting box is connected with the dedusting shield by the steel wire soft rubber pipe joint and a steel wire soft rubber pipe; the second level dedusting box is connected with a reducing tee at the lower end of the pumping and releasing branch pipe by the steel wire soft rubber pipe joint and a steel wire soft rubber pipe; a spraying mist inlet is formed in the upper end of each of the first level dedusting box and the second level dedusting box; W-shaped dedusting channels and butterfly valves are arranged in the first level dedusting box and the second level dedusting box. The coal seam pumping and releasing drilling negative pressure dedusting system solves the problems of large coal dust during drilling and large negative pressure during pumping and releasing fundamentally; the respirable dust at the drilling site is effectively controlled, the operation environment is improved, the safety loopholes caused by coal dust accumulation is avoided, the investment of later stage manual and dedusting cost is reduced and larger safety benefits are achieved.
Description
Technical field:
The utility model relates to a kind of dust pelletizing system, particularly relates to a kind of coal seam extraction boring depression dust-removing system, belongs to coal mining safety technics field.
Background technology:
Our a lot of collieries belong to two soft hard coal seams, and base plate is soft, coal seam is soft, top board is hard, and the present situation that mine generally faces is: the coal dust producing while 1. drilling is large, affects operating environment; 2. negative pressure of suction large (all more than 35Kpa), causes part boring that gas leak phenomenon occurs.In weak seam is drilled process, very easily occur the phenomenons such as plug-hole, bit freezing, spray orifice, the gas one of ejection is often to cause operation place and return gas exceeding limit, is unfavorable for safety management, once occur that gas combustion, gas explosion accident easily occur spark; The 2nd, the gas of ejection can not be collected in extraction pipeline, except waste resource, is also discharged in air and contaminated environment.
Utility model content:
Technical problem to be solved in the utility model is: a kind of coal seam extraction boring depression dust-removing system is provided, can effectively improves the working environment of drilling construction, improve the drilling efficiency in coal seam, eliminate the potential safety hazard in drilling construction; When rig creeps into coal seam, to the real-time extraction of the gas in coal seam, and accessible extraction pipeline, effectively prevents from transfiniting because gas accumulation causes gas bearing capacity in tunnel, ensures environment and the safety of construction.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of coal seam extraction boring depression dust-removing system, described coal seam extraction boring depression dust-removing system comprises dust excluding hood, extraction arm, primary dust removing case and two-stage dust removal case, between described primary dust removing case and two-stage dust removal case, is connected by flange; The upper end of described primary dust removing case and two-stage dust removal case respective side is provided with steel wire flexible rubber hose joint, described primary dust removing case is connected with dust excluding hood by steel wire flexible rubber hose joint and steel wire flexible rubber hose, and described two-stage dust removal case is connected with the reducing tee of extraction arm lower end by steel wire flexible rubber hose joint and steel wire flexible rubber hose.
Described primary dust removing case and two-stage dust removal case upper end are provided with spraying entrance; Described primary dust removing case and two-stage dust removal case inside are provided with " W " type dedusting passage and butterfly valve, are provided with butterfly valve spanner on butterfly valve.
While drilling, first open by-pass valve control, allow negative pressure connect the dust cover in aperture through two-stage dust removal case, primary dust removing case, suction coal dust filters through " W " of dust cleaning case type dedusting passage, at the dustproof water pipe of spraying entrance access, coal dust is down to dust cleaning case bottom, utilize butterfly valve spanner to discharge from butterfly valve.
The utility model from root solved while drilling that coal dust is large, large these two problems of negative pressure when extraction, effectively control the respirable dust in the place of drilling, improve operating environment, avoid coal dust to gather caused potential safety hazard, the input that has reduced artificial dedusting expense of later stage, has obtained larger safety benefit.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further explained and explanation:
Referring to Fig. 1, a kind of coal seam extraction boring depression dust-removing system, comprises dust excluding hood 1, extraction arm 7, primary dust removing case 10 and two-stage dust removal case 11, between primary dust removing case 10 and two-stage dust removal case 11, is connected by flange 5; Upper end in primary dust removing case 10 and two-stage dust removal case 11 respective side is provided with steel wire flexible rubber hose joint 3, primary dust removing case 10 is connected with dust excluding hood 1 by steel wire flexible rubber hose joint 3 and steel wire flexible rubber hose 2, and two-stage dust removal case 11 is connected with the reducing tee 8 of extraction arm 7 lower ends by steel wire flexible rubber hose joint 3 and steel wire flexible rubber hose 2.
Be provided with spraying entrance 4 at primary dust removing case 10 and two-stage dust removal case 11 upper ends, be provided with " W " type dedusting passage 12 and butterfly valve 9 at primary dust removing case 10 and two-stage dust removal case 11 inside, on butterfly valve 9, be provided with butterfly valve spanner 13.
On the steel wire flexible rubber hose 2 between two-stage dust removal case 11 and extraction arm 7, be provided with by-pass valve control 6.
While drilling, first open by-pass valve control 6, allow negative pressure connect the dust cover 1 in aperture through two-stage dust removal case 11, primary dust removing case 10, suction coal dust filters through " W " of dust cleaning case type dedusting passage 12, at the dustproof water pipe of spraying entrance 4 access, coal dust is down to dust cleaning case bottom, utilizes butterfly valve spanner 13 to discharge from butterfly valve 9.
The utility model from root solved while drilling that coal dust is large, large these two problems of negative pressure when extraction, effectively control the respirable dust in the place of drilling, improve operating environment, avoid coal dust to gather caused potential safety hazard, the input that has reduced artificial dedusting expense of later stage, has obtained larger safety benefit.
