Description
Technical field
The invention belongs to geological drilling field of engineering technology, are removed suitable for the various dust drillings using air as circulatory mediator
Dirt.
Background technology
Traditional large-scale advanced drilling equipment, is sent to cyclone separator dedusting, advantage is to remove after the dust of aperture by pipeline
Dirt effect is preferable, but since volume, weight are big, can not be applied on the landing stage of scaffold of anchoring engineering.It is set for small-sized probing
It is standby, dust-extraction unit is generally not provided with, proofing dust and protecting measure is only taken worker and combines well head covering plus water spray dust, although
It is at low cost, but dust removing effects are bad, pollute environment, influence workers ' health, dust is big to equipment damage.
The content of the invention
For above-mentioned technical problem, the present invention is intended to provide a kind of manufacture drilling equipment at low cost, good dedusting effect is used
Well head dust-extraction unit is particularly suitable for some drilling site conditions harshnesses, and the occasion that large scale equipment cannot go up scaffold operation uses,
Anchor shaft anchor cable drilling of the scaffolds operation such as high slope, deep basal pit and Unstable Rock Treatment etc., especially small-sized probing can be flexibly used for
Facilities air creeps into well head dedusting, effectively solves environmental pollution and protection worker's health.
For this purpose, the technical solution adopted in the present invention is：A kind of drilling equipment well head dust-extraction unit, including tubaeform collection
Dust hood, guide cylinder and deduster, the tubaeform dust gathering arrester are co-axially mounted rear enclosure on the drilling rod of drilling equipment with guide cylinder, institute
The big opening end for stating tubaeform dust gathering arrester covers in well head, and the pressure bladder by being close to well head prevents dust from leaking, the guiding
The upper end closed of cylinder is simultaneously provided with rubber seal on drilling rod via and realizes dynamic sealing, the drilling rod horizontal by angle α,
And 0 ° of 90 ° of ＜ α ＜, deduster are vertically installed at the underface of guide cylinder and are communicated with the inner cavity of guide cylinder, deduster is bilayer
Coaxial circular short tube, the annular interlayer that inner and outer pipes are formed is closed at both ends, and substantial amounts of hole for water spraying is distributed in inner tube, is set on outer tube
There is high pressure water access tube, when the air stream that dust is carried in drilling passes through deduster, the high pressure with high pressure water access tube feeding
The water and water mist inwardly sprayed through deduster inner tube hole for water spraying comes into full contact with, becomes wet bulb or mud, under the effect of gravity, through removing
It discharges dirt device bottom.
As the preferred of said program, the osculum end of the tubaeform dust gathering arrester perpendicular to drilling rod, tubaeform dust gathering arrester
Big opening end is obliquely installed with respect to drilling rod, the inclined hole drilling well for different angle, it is only necessary to replace tubaeform dust gathering arrester, it is ensured that loudspeaker
The big opening end diameter of shape dust gathering arrester is consistent, you can realizes the general of pressure bladder.
Further, the tubaeform dust gathering arrester is welded and fixed with guide cylinder, and deduster is welded and fixed with guide cylinder, welding peace
The sealing effect of dress is more preferable.
The beneficial effects of the invention are as follows：It is simple in structure, manufacture it is at low cost, light-weight, occupy little space, can flexibly be used for height
The anchor shaft anchor cable drilling of the scaffolds operation such as side slope, deep basal pit and Unstable Rock Treatment；Dust is made using totally enclosed type high pressure water veil
Become wet bulb or mud, and be automatically drained out using gravity, it is achieved thereby that green probing, effectively solves environmental pollution and protection work
The sky in addition to large scale equipment operation has been filled up in human body health, the well head dedusting being adapted under all devices and execution conditions
Pneumatic drill is into dedusting blank.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the deduster perspective view with high pressure water access tube.
Specific embodiment
By way of example and in conjunction with the accompanying drawings, the invention will be further described：
As shown in Figure 1, a kind of drilling equipment well head dust-extraction unit, mainly by tubaeform dust gathering arrester 1, guide cylinder 2, dedusting
Device 3, pressure bladder 4, high pressure water access tube 5 form.
Tubaeform dust gathering arrester 1 is co-axially mounted rear enclosure on the drilling rod 6 of drilling equipment with guide cylinder 2, it is preferable that tubaeform collection
Dust hood 1 is welded and fixed with guide cylinder 2.
Tubaeform dust gathering arrester 1 divides big opening end and osculum end, and the big opening end of tubaeform dust gathering arrester 1 covers in well head, and passes through tight
The pressure bladder 4 of patch well head prevents dust from leaking, and the osculum end of tubaeform dust gathering arrester 1 is welded with the lower end of guide cylinder 2.
The upper end closed of guide cylinder 2 is simultaneously provided with rubber seal realization dynamic sealing on drilling rod via, and drilling rod 6 was crept into
Cheng Zhong, tubaeform dust gathering arrester 1, guide cylinder 2, deduster 3, pressure bladder 4, high pressure water access tube 5 are fixed not as an entirety
It is dynamic.
Drilling rod 6 is horizontal by angle α, and 0 ° of 90 ° of ＜ α ＜, deduster 3 are vertically installed at the underface of guide cylinder 2, and
It is communicated with the inner cavity of guide cylinder 2, deduster 3 is welded and fixed with guide cylinder 2.
As shown in Figure 1, Figure 2, deduster 3 is double-layer coaxial circular short tube, two end seal of annular interlayer that inner and outer pipes are formed
It closes, substantial amounts of hole for water spraying 3a is distributed in inner tube, high pressure water access tube 5 is provided on outer tube.
When carrying the air stream of dust by deduster 3 in drilling, the high pressure water and warp be sent into high pressure water access tube 5
The water mist that 3 inner tube hole for water spraying 3a of deduster inwardly sprays comes into full contact with, and becomes wet bulb or mud, under the effect of gravity, through dedusting
It discharges 3 bottom of device.
The osculum end of tubaeform dust gathering arrester 1 is set perpendicular to drilling rod 6, the big opening end of tubaeform dust gathering arrester 1 with respect to the inclination of drilling rod 6
It puts, the inclined hole drilling well for different angle, it is only necessary to replace tubaeform dust gathering arrester 1, it is ensured that the big opening end of tubaeform dust gathering arrester 1 is straight
Footpath is consistent, you can realizes the general of pressure bladder 4.
The dust generated in drilling process along the gap between drilling and hole wall is blown out using gases at high pressure in drilling rod, is led to
The big opening end for crossing tubaeform dust gathering arrester 1 covers in well head, can preferably collect dust, and dust is finally blown to guide cylinder 2, deduster
3 connect pressure water by high pressure water access tube 5 forms interior spray high pressure water veil, contacts to form wet bulb or mud with dust, through dedusting
It discharges 3 bottom of device.Since deduster 3 is arranged on the underface of guide cylinder 2, dust is once contacted with high-pressure water mist just becomes wet bulb
Or mud, dust removing effects are very good.
