Description
Technical field
The invention belongs to mining technical field, be specifically related to a kind of extraction drilling dust collecting device.
Background technology
Gas is the accompanying gas that coal is formed in coalification course, colourless, tasteless, have burning and explosive, forms security threat to coal production; According to ocurrence of coal seam state and the continuous deepening along with pit mining, gas control more and more becomes the key factor of restriction mine safety, High-efficient Production.Administer the main method of gas now, be still and utilize construction extraction boring to carry out gas drainage under suction, carrying out concentrating to extract out discharging or utilizing with the free and analysable gas in coal seam by composing to deposit, to reduce seam gas content, realizing safety, High-efficient Production.
And carry out in the process of gas drainage under suction in utilization construction extraction boring, can return along boring produce coal (rock) dirt and a small amount of gas, return (rock) dirt that produces coal and can have a strong impact on operating environment, a small amount of gas returned out can cause spray orifice.Adopt traditional aperture spray method or blowout prevention aperture apparatus to solve above-mentioned technical problem in prior art, but find at work progress, easily cause to aperture spraying way of escape blocking of drilling, dust-laying effect is poor, the unsuitable centralized collection of coal dust, operating environment are poor; When blowout prevention aperture apparatus uses, previous work amount is comparatively large, reduces the defects such as efficiency of drilling.
Summary of the invention
The object of the invention is to solve the above-mentioned technical problem existed in prior art, a kind of extraction drilling dust collecting device is provided.
For achieving the above object, the technical solution used in the present invention is as follows:
Extraction drilling dust collecting device of the present invention, this dust collect plant comprises dust arrester and plenum chamber, and dust arrester comprises dust arrester cavity, dust arrester cavity one sidewall is provided with positioning through hole, relative sidewall is provided with movable door, and active catch covers and is provided with drilling rod through hole; Be provided with atomization mechanism in dust arrester cavity bottom, be provided with in dust arrester bottom and connect dirt passage, be provided with gas bleed off pipe at dust arrester top; Plenum chamber top is provided with admission pipe and extraction interface, and gas bleed off pipe is connected by tube connector with between admission pipe.
The present invention is preferably provided with baffle plate in the outside of the movable door of dust arrester, to increase the sealing performance of dust arrester cavity.
The present invention is preferably provided with dust-break gauze at dust arrester top.
In plenum chamber, be provided with dust board, described dust board is crisscross arranged.
Described tube connector is wired hose.
The analysis that the present invention is applied by air exercise driller's skill and traditional aperture spray method, blowout prevention aperture apparatus technology, easily cause way of escape blocking of drilling in conjunction with spraying to aperture, hole under construction, dust-laying effect is poor, the unsuitable centralized collection of coal dust, operating environment are poor, and during the use of blowout prevention aperture apparatus, previous work amount is comparatively large, reduces the defects such as efficiency of drilling; According to aerodynamics and dust aerosol principle, from construction drill physical condition, what research and design went out repeatedly to drill the coal dust, chip and the methane gas gushed out that return out in process for centralized collection, reduce job location airborne dust, improvement operating environment, improves a kind of device of construction safety coefficient and efficiency.
The features such as it is little, lightweight, simple to operate that extraction drilling dust collecting device of the present invention has volume, conveniently moving, cleaning operation, and dust collecting effect is good.Effectively can collect the airborne dust of 85%, improvement operating environment, collects the gas of holing and gushing out in time, reduces gas density near operating location, improves construction drill safety factor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Extraction drilling dust collecting device of the present invention as shown in Figure 1, comprise dust arrester 8 and plenum chamber 16, dust arrester 8 comprises dust arrester cavity, and dust arrester cavity one sidewall is provided with positioning through hole 7, relative sidewall is provided with movable door 3, and movable door 3 is provided with drilling rod through hole; Be provided with baffle plate 5 in the outside of the movable door 3 of dust arrester, baffle plate 5 and door 3 are provided with fixing hole 9, are fixed on door 3 by screw by baffle plate 5, to increase the sealing of dust arrester cavity.
Be provided with atomization mechanism 6 in dust arrester cavity bottom, described atomization mechanism can be high-pressure sprayer or other atomization mechanism be applicable to.Be provided with in dust arrester bottom and connect dirt path 10, connect dirt bag and fixed by retainer plate 11.
Be provided with dust-break gauze 2 at dust arrester 8 top, be provided with gas bleed off pipe 1 at dust arrester top; Plenum chamber 16 top is provided with admission pipe 13 and extraction interface 15, is provided with dust board 14 in plenum chamber, and described dust board 14 is crisscross arranged.Be connected by tube connector 12 between gas bleed off pipe 1 with admission pipe 13.Described tube connector is wired hose.
Installation process of the present invention is as follows:
When coal mine down-hole tunnel construction gas extraction hole, reserve behind orientation and inclination angle until rig, dust arrester is arranged on tunnel sidewall by positioning through hole 7 or meets the tapping point position of wall; Before perforate, dust arrester door 3 is opened, carry out determining hole operation, after drilling tool perforate, door puts down, and after being fixed by baffle plate 5, connects the gas bleed off pipe 1 on dust arrester and the admission pipe 13 on plenum chamber with wired hose 12, and the extraction interface on plenum chamber and drainage system are connected, can construction drill be started.While starting construction drill, atomization mechanism be opened, and according to drilling gas effusion intensity size in operation process, adjustable pipe switch door, controls flow and carries out extraction.
Operating principle of the present invention is as follows:
In construction firedamp taking-out discharging drilling process, the coal dust returned out in boring is separated by dust arrester 8 with coal chip, and by the downward atomizing de-dusting of atomization mechanism 6, coal chip and part coal dust are carried out separated and collected, connect dirt bag, pack process by connecing the inflow of dirt path 10.The dust flown upward rises by air force and suction function, by dust-break gauze 2, the larger dust of part is carried out secondary separation, floating dust after separation and gas enter the admission pipe 13 of plenum chamber 16 through gas bleed off pipe 1 and steel wire tube 12, in gas collection casing, floating dust is through the circulation dust-break effect of dust board 14, third time separation is carried out in the stop of portion's part dust, sedimentation, gas after separation enters drainage system through extraction interface 15, completes the continuous purification of dust and gas, collection process.
