Abstract
The invention discloses a steam jet drill bit which comprises a three-wing drill bit body, a multi-stage steam generator, a steam nozzle, high-frequency heaters, a drill rod and the like. High-pressure water jet is heated through the multi-stage steam generator in a graded mode to be transformed into high-pressure steam jet. Meanwhile, the high-pressure state and stable vaporizing pressure of the steam jet can be kept through the high-frequency heaters arranged on the three-wing drill bit body. Compared with a high-pressure water jet technology, rock debris in a hole can be completely discharged better through the steam jet technology; meanwhile, the high-pressure steam jet can enter a clearance between a drilling tool and rock, therefore, the protection effect similar to that of a hovercraft is generated, the drilling speed is increased, the drill bit is protected, and the drilling process is more stable.
Description
Technical field
The present invention relates to Rock penetrating technical field, in particular to a kind of steam jet drill bit.
Background technology
In current coal, petroleum gas and tunnel construction development process, hard rock and ultrahard rock location drilling difficulty are shadows
Ring the key link of construction speed.For example, in some solid rock locations, daily rate of penetration only has several meters of even zero points several
Rice.And cutter expense accounts for larger proportion in hard-rock boring construction cost, Shi Zhiyue is hard, and cutter cost ratio is higher, particularly
Superhard rock location driving, cutter expense for excavation cost 1/3rd.Therefore, drilling efficiency is improved, reduces cutter consumption, be
Reduce the main target of hard rock excavation cost, the even more basic task of the Important Project such as energy development, tunnel construction.
Although adopting the NEW TYPES OF TOOL MATERIALSs such as diamond, ceramic coating carry to a certain extent by research at present
The wearability of high cutter, but the low problems of drilling efficiency such as the bit freezing that chip removal is not freely caused but still cannot be solved, and this
NEW TYPES OF TOOL MATERIALS is with high costs a bit is difficult to spread.Although high-pressure water jet auxiliary Rock penetrating technology contributes to expansion
Rock fracture further improves rate of penetration, but the service life of drill bit is still relatively low；In addition, high-pressure water jet also can be to drill bit
Certain resistance is produced, drill speed is reduced, and a large amount of water are piled up with the mixed mud of landwaste and chip removal can be caused difficult very
Drilling efficiency is affected further to bit freezing.
Therefore, hard rock drill bit drilling efficiency is improved, extending drilling life of bit must consider to existing drill bit from multi-angle
Technology is reformed.
The content of the invention
To solve the technical problem existing for prior art, the invention provides a kind of steam jet drill bit.
The technical solution adopted in the present invention is：A kind of steam jet drill bit includes three-wing bit, multistage steam generator,
Insulating barrier, steam jet, drilling rod, heating generator, rosette, conductor wire etc..By multistage steam generator to from drilling rod stream
The high-pressure water jet for entering carries out progressive solution so as to change into high steam jet.Simultaneously using the height arranged on three-wing bit
Frequency heater makes steam jet maintain the condition of high temperature and stable pressure for vaporization.
It is an advantage of the current invention that：
1. there is this steam jet drill bit air cushion drag reduction and high steam to protect the effect of drill bit.Steam is in bit
Marginal portion and rock surface form air cushion, are conducive to reducing friction, increase rotating speed, improve drilling efficiency；High-frequency heating simultaneously
Device is conducive to the maximum pressure for maintaining steam, and then makes bit face in the protection of high steam, prevents bit wear, carries
High cutter life.
2. this steam jet drill bit can improve drilling efficiency.High steam can occur vapour-liquid phase-state change, acute in this
The shock effect to rock is produced in strong phase-state change, is conducive to cutter crushed rock, improve drilling efficiency.
3. this steam jet drill bit can form vortex chip removal, improve chip removal efficiency.Steam is from the spray orifice less than acting surface
Place projects, and then full of the gap between drill bit three wings and rock, and as drill bit levels off to high speed uniform rotation, steam is with nozzle
On the basis of axis, axle forms vortex so that the rock for cutting will not deposit, be blocked between drill bit three wings, while also driving
Aggregate chips outwards rotates blowout, improves chip removal efficiency.
