Abstract
The utility model provides a novel drilling dustproof and blowout-preventing device which comprises a box capable of preventing dust and blowout. The front end of the box is connected with a supporting pipe through a flange, and a drill rod in/out device is arranged at the rear end of the box and corresponds to the supporting pipe; a gas drainage pipe opening is formed in one side of the top of the box, and the lower portion of the box is provided with a cylindrical through hole which is tightly connected with a slag bag; an expansion device is arranged on the left side of the box. The novel drilling dustproof and blowout-preventing device can seal gas, dust and rock slag generated in hole drilling in the box, water, dust and slag generated in the box is discharged, gas and other harmful gases are exhausted by the gas drainage pipe, diffusion of methane gas and poisonous gas is reduced, and the purposes of purifying the work environment, improving work efficiency and achieving safe production can be achieved. The novel drilling dustproof and blowout-preventing device has wide practicability and anti-explosion performance, the gas drainage effect can reach 95%, and the device has the advantages of being low in weight, small in size, simple in installation, convenient to convey, scientific and reasonable in design, high in efficiency, and suitable for being widely popularized and applied.
Description
Technical field
The utility model relates to coal mine drilling dust guard pollution abatement equipment technical field, specifically a kind of Novel drilling preventing dust spray apparatus.
Background technology
At present in coal mine gas drilling environment; coal seam driving or coal mining manufacturing process; in drilling process, be prone to ejection gas pernicious gas, dust, outstanding coal; often can meet with the prominent spray of gas or the gas density phenomenon that transfinites; the very big mine production safety that affects, is the generation of eliminating Gas Outburst, and relevant Coal Exploitation is front at coal seam drilling slotted hole with producing; to discharge the technique of gas in advance, eliminate this potential safety hazard.But in boring procedure, also can run into the prominent spray of gas or the gas density phenomenon that transfinites, human casualty accident occurs.At present, relevant Coal Exploitation blowout prevention frame, blowout prevention plate etc., prevent the prominent spray of gas to injure staff and equipment, current each ore deposit two kinds of modes of having drilled, the first is that water coordinates drilling, its advantage is to prevent dust, can avoid temperature of diamond bit to raise, shortcoming is easy bit freezing bar, and the progress of drilling is slow, and ejection gas and coal cannot solve.The second is to coordinate drilling with gas, and this method advantage is that bit freezing bar is few, and progress is fast.But ejection gas and coal, dust still cannot solve, and drill bit can produce uniform temperature.Present each ore deposit adopts spraying or administers with mobile pump gas pumping, but effect is not good enough, can not fundamentally solve dustproof, anti-gas exceeding limit problem, and blowout prevention aspect also exists the coal powder injection slag of dashing forward to injure the potential safety hazard of operating personnel and equipment.
Summary of the invention
The utility model provides a kind of totally enclosed device to prevent that gas, dust, rock slag are excessive, the Novel drilling preventing dust spray apparatus of outer spray.
Boring preventing dust spray apparatus of the present utility model, by the following technical solutions: comprise the casing of the blowout prevention dress use of can preventing dust, described casing front end connects stay pipe by flange, is positioned at box back and opposite position place, stay pipe position drilling rod access apparatus is installed; Casing top one side is installed the gas drainage under suction mouth of pipe, and lower box arranges cylindrical hole and is closely connected with slag bag; Expansion gear is installed in casing left side.The external mine gas drainage pipe network of gas drainage pipe, the gas and coal dust that boring is produced rushes at sucking-off in body; Stay pipe can insert rock mass, is fixed in rock mass, and its outer end is provided with flange, plays the effect of support, fixing blowout prevention dirt seal housing; Meanwhile, it is also the passage that drilling rod is come in and gone out, in the time that drilling rod advances to rock mass, produced gas, dust, rock slag is wherein airtight, is delivered in blowout prevention dustproof case body.
Further, drilling rod access apparatus comprises diaphragm seal and bearing composition, diaphragm seal circular hole in the middle of it, circular make several mutually superpose or slitless connection play sheet.
Further, bearing is connected with diaphragm seal by the connecting hole on other members and diaphragm seal, its role is to reduce the wearing and tearing of drilling rod to diaphragm seal, and can help drilling rod access apparatus to play a role more freely.
Further, expansion gear is made up of air bag and horn-like cylinder.
Further, air bag material can be selected rubber or cloth any all can.
Air bag is inflation as balloon, is connected with blowout prevention dirt seal housing, and inside communicates, externally airtight, can pass through gas; Horn-like cylinder plays splendid attire air bag, and prevents that air bag from coming off or being squeezed; The function of expansion gear is in the time of the prominent spray of gas, as releasing pipe has little time gas to extract out, the high pressure gas of prominent spray, just be filled with air bag, air bag expands thereupon and has just cushioned the impact of high pressure gas to blowout prevention dirt seal housing, has also limited to greatest extent gas overflowing simultaneously.
Blowout prevention dustproof case body repetition test of the present utility model is known: the gas that boring can be produced, dust, rock slag is enclosed in casing, by the water producing in casing, ash, slag, discharge, the pernicious gases such as gas are discharged through gas drainage pipe, reduce methane gas, the diffusion of toxic gas, can realize working environment purifies, improve work efficiency, the object of safety in production, there is extensive practicality, and there is explosion-proof performance, take out ejection gas effect and reach 95%, have lightweight, volume is little, install simple, convenient transportation, design science is reasonable, the feature that efficiency is high, suitablely generally apply.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model diaphragm seal structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of Novel drilling preventing dust spray apparatus, comprises that the blowout prevention of can preventing dust fills the casing 1 of use, and described casing 1 front end connects stay pipe 2 by flange, is positioned at box back and opposite position place, stay pipe position drilling rod access apparatus 3 is installed; Casing 1 top one side is installed the gas drainage under suction mouth of pipe 4, and casing 1 bottom arranges cylindrical hole 5 and is closely connected with slag bag 6; Expansion gear 7 is installed in casing 1 left side.Drilling rod access apparatus comprises diaphragm seal 10 and bearing composition, diaphragm seal circular hole in the middle of it, circular make several mutually superpose or slitless connection play sheet 11.Expansion gear 7 is made up of air bag 8 and horn-like cylinder 9.Air bag material can be selected rubber or cloth, and any all can.When the utility model uses, stay pipe is inserted to rock stratum, be fixed in rock stratum, by flange, blowout prevention dirt seal housing and stay pipe are fixed together, by the miscellaneous part connection of blowout prevention dirt seal housing, after stable connection, insert at the center of diaphragm seal and stay pipe that drilling rod is aimed at, check drilling rod, diaphragm seal, stay pipe three whether with one heart after, open after gas drainage under suction tube valve, can implement boring, in the time that rock slag is filled slag bag, suspend boring, slag bag is taken off and emptied or Reusability, continue start boring, so circulation, until complete bore operation.The utility model does not describe part in detail and is known technology, and the common variation that those skilled in the art carries out within the scope of technical solution of the present invention or replacement all should be included in protection scope of the present invention.
