Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
As shown in Figs. 1-2, the present invention provides a kind of coal mine down-hole drilling blowout prevention dust-extraction unit, comprising: drilling disk 1, drilling rod
Through-hole 2, air cleft 4, dust gathering arrester 3, steering tube 5, vibration absorber 6, spray head 17, water tank 11, blowout prevention air bag 9, blowout prevention plane of weakness 7, blowout prevention
Pipe 8, gas drainage under suction mouth 10, slag notch 12, transfer tube 13, high-pressure hydraulic pump 14, Venturi tube 15, slag-drip opening 16, basic surface are living
Property agent solution 18, hose 19.
Before drilling construction, down-hole drilling blowout prevention dust-extraction unit is connected by vibration absorber 6 with drilling machine first, starts high pressure
Water pump 14 makes the spray head 17 in its Venturi tube 15 start to work, and sprays water mist and forms certain negative pressure in drilling disk 1,
Certain suction is generated at annular air cleft 4.
When starting drilling, drill bit adjusts the angle with working face by steering tube 5, and bore angle can be adjusted between ± 45 degree
Section, it is ensured that can smooth operation on Multi-angle working face.The dust that drilling generates is collected into drilling disk 1 by dust gathering arrester 3,
The little particle dust that part does not enter into dust gathering arrester 3 can be drawn into drilling disk 1 by annular air cleft 4, and secondary receipts are formed
Collection, improves the collection efficiency of dust.Dust in sucking drilling disk 1 can enter the text of 1 lower section of drilling disk since pressure acts on
It in venturi 15, is dusted in Venturi tube 15 by the water mist that spray head 17 sprays, which is to store in water tank 11
The base surfactant solutions 18 deposited, the Turbulent Flow Field in Venturi tube 15 increase the probability that dust is contacted with water mist, separately
Outer base surfactant solutions 18 play good wet effect due to its surface-active, to dust, improve efficiency of dust collection.
In boring procedure, when spray orifice phenomenon occurs, the gentle cognition of a large amount of particulate matters of ejection is directly entered drilling
In disk 1, particulate matter is sprayed on vibration absorber 6 with gas is sprayed, and vibration absorber 6 can share a part of pressure, vibration absorber 6
Unidirectional baffle dust sprayed from drilling rod through-hole, reduce damage of the drilling spray orifice to equipment.Blowout prevention below vibration absorber 6
Plane of weakness 7 is broken up at first, is flowed into lubricator 8 at the cut that particulate matter passes through drilling plane of weakness 7 with ejection gas, ejection
Dust and gas open 9 moment of blowout prevention air bag, and blowout prevention air bag 9 quickly collects ejected matter；Drill spray orifice generate gas and
Dust can then move further into hose 19, and gas enters water tank 11 by hose 19；When spray orifice gas is carbon dioxide,
Carbon dioxide can be absorbed in base surfactant solutions 18；When spray orifice gas is methane, through base surfactant solutions
The methane of filtering is discharged into mine gas drainage pipeline via drawing-off gas mouth 10, after the dust in ejecta is by deposition, through going out
Cinder notch 12 is discharged.
