Technical field
The invention belongs to field of mechanical technique, relate to a kind of mine equipment equipment, be specifically related to a kind of mining drilling gas drainage device.
Background technology
Frequently there is casualties and dead accident in current underground coal mine, security incident takes place frequently, according to the data display of national Administration of Work Safety Supervision: since founding of New, 24 once above serious accidents of dead hundred people occur altogether in colliery, wherein 21 is gas accident, so gas is undisputed Safety of Coal Mine Production " the first killer ".Gas drainage under suction work during drill mash gas device may be used for holing.Spray orifice, Gas Outburst chance etc. during the present invention is punched to the discharge in underground work space, reduction during holing by reduction gas, thus improve mine safety production level.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of mining drilling gas drainage device, be a kind of adopt centrifugation and sedimentation theory realize water, gas, ash content of coal from device, thus the gas drainage under suction during realizing boring, in order to reduce the spray orifice, Gas Outburst chance etc. during gas punches to the discharge in underground work space, reduction during holing, thus improve mine safety production level.
Its technical scheme is as follows:
A kind of mining drilling gas drainage device, mainly comprises with the drill sleeves 1 of tapping screw thread, endoporus has spiral fluted drilling rod sleeve 2, inwall has tank spherical extraction body 3, reticulum 4; 7, screen pack 5, gas drainage under suction interface tube 6, built-in deep groove ball bearing 8, port angular contact ball bearing outer ring 9, adjustment back-up ring 10, liquid, coal ash floss hole 11, it is characterized in that, drill sleeves 1 is connected with drilling rod sleeve 2 by screw thread, drilling rod sleeve 2 is connected with spherical extraction body 3 by screw thread, gas drainage under suction interface tube 6 is directly welded on spherical extraction body 3, and screen pack 5 is arranged on the reticulum 4 be fixed on spherical extraction body 3; On 7, play filter dust particle, purification methane gas, built-in deep groove ball bearing 8 is arranged on the port inner wall of spherical extraction body 3, and port angular contact ball bearing outer ring 9 is arranged on the port inner wall of spherical extraction body 3, and liquid, coal ash floss hole 11 are directly welded on spherical extraction body 3.
Beneficial effect of the present invention: the invention provides a kind of adopt centrifugation and sedimentation theory realize water, gas, ash content of coal from device, thus the gas drainage under suction during realizing boring, in order to reduce the spray orifice, Gas Outburst chance etc. during gas punches to the discharge in underground work space, reduction during holing, thus improve mine safety production level.
Accompanying drawing explanation
Fig. 1 is the structural representation of mining drilling gas drainage device.
Detailed description of the invention
Below in conjunction with accompanying drawing detailed description of the invention, technical scheme of the present invention is described in more detail.
A kind of mining drilling gas drainage device, mainly comprises with the drill sleeves 1 of tapping screw thread, endoporus has spiral fluted drilling rod sleeve 2, inwall has tank spherical extraction body 3, reticulum 4; 7, screen pack 5, gas drainage under suction interface tube 6, built-in deep groove ball bearing 8, port angular contact ball bearing outer ring 9, adjustment back-up ring 10, liquid, coal ash floss hole 11, it is characterized in that, drill sleeves 1 is connected with drilling rod sleeve 2 by screw thread, drilling rod sleeve 2 is connected with spherical extraction body 3 by screw thread, gas drainage under suction interface tube 6 is directly welded on spherical extraction body 3, and screen pack 5 is arranged on the reticulum 4 be fixed on spherical extraction body 3; On 7, play filter dust particle, purification methane gas, built-in deep groove ball bearing 8 is arranged on the port inner wall of spherical extraction body 3, and port angular contact ball bearing outer ring 9 is arranged on the port inner wall of spherical extraction body 3, and liquid, coal ash floss hole 11 are directly welded on spherical extraction body 3.
During the work of mining drilling gas drainage device, first the drill sleeves 1 with tapping screw thread by being rotatably mounted in boring, then be connected with drilling rod sleeve 2 by internal thread, drilling rod sleeve 2 is connected with spherical extraction body 3 by internal thread, again gas drainage pipe is connected on gas drainage under suction interface tube 6, water, grey delivery pipe are connected on liquid, coal ash floss hole 11, and borer drill rod inserts boring by the position, axis shown in Fig. 1 and gets final product work.
The course of work:
When applying, flow in drilling rod sleeve 2 by boring under the negative pressure extraction effect of the gas drainage pipe that main actions flow process connects at gas drainage under suction interface tube 6 for: the gas that boring procedure discharges, and enter spherical extraction body 3 by drilling rod sleeve 2, under the negative pressure extraction effect of gas drainage pipe connected at gas drainage under suction interface tube 6 and the turning effort of spherical extraction body 3 spiral inner wall groove, centrifugation and sedimentation theory is utilized to realize water, gas, the separation of coal ash, thus realize gas and discharge from gas drainage under suction interface tube 6, water, coal ash is from liquid, coal ash floss hole 11 is discharged.
The above, be only best mode for carrying out the invention, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses, and the simple change of the technical scheme that can obtain apparently or equivalence are replaced and all fallen within the scope of protection of the present invention.
