Description
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 boring gas drainage device.
Background technology
Casualties and dead accident frequently appear under the coal mine at present; Security incident takes place frequently; Show according to national Administration of Work Safety Supervision data: 24 above serious accidents of once dead hundred people take place in colliery altogether since the founding of New; Wherein 21 is gas accident, so gas is undisputed Safety of Coal Mine Production " first killer ".Gas drainage under suction work during the boring gas drainage device can be used to hole.The present invention gives prominence to chance etc., thereby improves the mine safety level of production to the discharging in underground work space, spray orifice, the gas that reduces during punching during holing through reducing gas.
Summary of the invention
In order to solve the problems of the technologies described above; The present invention provides a kind of mining boring gas drainage device; Be that a kind of centrifugation and sedimentation theory of adopting realized the device that water, gas, ash content of coal leave; Thereby realize the gas drainage under suction during the boring,, thereby improve the mine safety level of production in order to reduction the gas spray orifice during discharging, the reduction in underground work space are punched, the outstanding chance of gas etc. during holing.
Its technical scheme is following:
A kind of mining boring gas drainage device comprises that mainly the boring sleeve 1, the endoporus that have tapping screw thread have spherical extraction body 3, reticulum 4 that spiral fluted drilling rod sleeve 2, inwall have tank; 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; Boring sleeve 1 links to each other with drilling rod sleeve 2 through screw thread; Drilling rod sleeve 2 links to each other with spherical extraction body 3 through screw thread, and gas drainage under suction interface tube 6 directly is welded on the spherical extraction body 3, and screen pack 5 is installed in the reticulum 4 that is fixed on the spherical extraction body 3; On 7; Work to filter dust granule, purify methane gas; Built-in deep groove ball bearing 8 is installed in the port inner wall of spherical extraction body 3, and port angular contact ball bearing outer ring 9 is installed in the port inner wall of spherical extraction body 3, and liquid, coal ash floss hole 11 directly are welded on the spherical extraction body 3.
Beneficial effect of the present invention: the present invention provides a kind of centrifugation and sedimentation theory of adopting to realize the device that water, gas, ash content of coal leave; Thereby realize the gas drainage under suction during the boring; Give prominence to chance etc., thereby improve the mine safety level of production to the discharging in underground work space, spray orifice, the gas that reduces during punching during holing in order to reduce gas.
Description of drawings
Fig. 1 is the structural representation of mining boring gas drainage device.
The specific embodiment
Below in conjunction with the accompanying drawing specific embodiment technical scheme of the present invention is done explanation in further detail.
A kind of mining boring gas drainage device comprises that mainly the boring sleeve 1, the endoporus that have tapping screw thread have spherical extraction body 3, reticulum 4 that spiral fluted drilling rod sleeve 2, inwall have tank; 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; Boring sleeve 1 links to each other with drilling rod sleeve 2 through screw thread; Drilling rod sleeve 2 links to each other with spherical extraction body 3 through screw thread, and gas drainage under suction interface tube 6 directly is welded on the spherical extraction body 3, and screen pack 5 is installed in the reticulum 4 that is fixed on the spherical extraction body 3; On 7; Work to filter dust granule, purify methane gas; Built-in deep groove ball bearing 8 is installed in the port inner wall of spherical extraction body 3, and port angular contact ball bearing outer ring 9 is installed in the port inner wall of spherical extraction body 3, and liquid, coal ash floss hole 11 directly are welded on the spherical extraction body 3.
When mining boring gas drainage device is worked; At first be installed in the bar cover with tapping screw thread 1 in the boring through rotation; Link to each other with drilling rod sleeve 2 through internal thread then, drilling rod sleeve 2 links to each other with spherical extraction body 3 through internal thread, is connected on the gas drainage under suction pipe on the gas drainage under suction interface tube 8 again; Water, grey delivery pipe are connected on liquid, the coal ash floss hole 11, and borer drill rod inserts boring through the position, axis shown in the figure one and gets final product work.
The course of work:
When using; Main motion flow is: the gas that boring procedure discharged flows in the drilling rod sleeve 1 through boring under the negative pressure extraction effect of the gas drainage under suction pipe that gas drainage under suction interface tube 6 is connected; And through the spherical extraction body 3 of drilling rod sleeve 2 entering; Under the turning effort of the negative pressure extraction effect of the gas drainage under suction pipe that gas drainage under suction interface tube 6 is connected and spherical extraction body 3 spiral inner wall grooves; Utilize centrifugation and sedimentation theory to realize separating of water, gas, coal ash, thereby realize that gas discharges from gas drainage under suction interface tube 6, water, coal ash are from liquid, 11 discharges of coal ash floss hole.
The above is merely best mode for carrying out the invention, and any technician who is familiar with the present technique field is in the technical scope that the present invention discloses, and the simple change of the technical scheme that obtains or equivalence replacement all fall in protection scope of the present invention with may be obvious that.
