Description

Air drill pore-forming and creep into cleaner
Technical field
The invention belongs to mechanical field, particularly a kind of cleaner be applicable in the drilling construction process of lithostratigraphy.
Background technology
Along with country is to the further attention of stone cultural artifact protection work, scope and the dynamics of historical relic's protection work increase all further.One of conventional means that anchoring is protected as stone cultural artifact, deposits rock mass in historical relic tax and widely uses.Rig can be divided into air drill, electric drill, hydraulic drill, and air drill is most widely used on Anchor cable-rod pore-forming.A large amount of dirt slags will be produced among the perforate of air drill and drilling process.Dust can be floating more than 1 kilometer, larger to the workers ' health infringement being engaged in construction; To scenic spot open and the visit of visitor has a negative impact; Dust drops on historical relic body surface also can produce pollution to historical relic body.
For the particularity of historical relic's protection work, the generation of the cleaner of air drill just becomes a kind of inevitable.The existing patent utility model patent " a kind of environmental protection dust collector " that to be number of patent application be " 201020170298.8 ".There are following three problems in this dust collector:
1, dust collector obturation effect is bad, still has a large amount of dust to overflow, or causes certain injury to constructor, if constructed near historical relic body, still produces historical relic body to a certain extent and pollutes;
2, slag dirt enters dust remover by bounce-back, and after bounce-back, speed reduces, and the effect entering dust remover is bad, and does not carry out the separation of slag dirt, is often forced to stopping because dust elimination is not smooth and creeps into work;
3, perforate dedusting relevant device is not had.
Summary of the invention
The object of this invention is to provide a kind of air drill pore-forming and creep into cleaner, to solve the bad problem of existing dust collector obturation effect.
For achieving the above object, the present invention is by the following technical solutions:
A kind of air drill pore-forming and creep into cleaner, comprise deduster, dust collects device, described deduster is provided with streamlined threeway, the afterbody of described streamlined threeway is connected with described dust and collects device, dynamic sealing device and static seal device is provided with in described deduster, described dynamic sealing device comprises at least two-layer active blade be enclosed within drilling rod, described active blade is circular that an aperture is greater than drill pipe diameter, and described static seal device is the medium of the Absorbable rod dust being arranged on deduster afterbody.
Described active blade is two-layer, be respectively the first active blade and the second active blade, described first active blade and the second active blade are successively set on the afterbody of drilling rod, described first active blade and the lower end of the second active blade and the contact internal walls of deduster, be provided with nut before described first active blade, after described first active blade, be provided with baffle plate; Described second active blade is arranged on the tail end of deduster, is provided with afterbody nut before described second active blade; Described static seal device is provided with between described first active blade and the second active blade.
As further improvement of the present invention, described dynamic sealing device also comprises the 3rd active blade, and described 3rd active blade is arranged on the front side of the fairing member in described streamlined threeway.
The aperture of described active blade is greater than drill pipe diameter 6mm ~ 10mm.
The described medium being arranged on the Absorbable rod dust of deduster afterbody is sponge.
Improve as another item of the present invention, described streamlined threeway and dust are collected between device and are provided with slag dirt eliminator.
Improve as another item of the present invention, be provided with horn mouth dust cover at deduster opening part.
The invention has the beneficial effects as follows:
1, deduster drilling rod seal approach is increased.
Three layers of active blade are adopted to carry out movable sealing.Active blade because centrifugal force rotates or vibration with drilling rod, forms movable sealing under drilling rod drives.The dust adsorption such as filling sponge between two-layer active blade, forms static seal.Movable sealing and static seal is adopted to want the sealing means combined, good sealing effect.
2, slag dirt guidance mode and processing mode is improved.
Streamlined threeway is adopted to guide dust to enter slag dirt eliminator.Slag dirt guiding port adopts fairing member, guides slag dirt to enter slag dirt eliminator with air-flow, guides better effects if.Slag dirt eliminator is set, slag dirt enters slag dirt eliminator along fairing member from instrument lower passage, its principle is that rock slag and part dust are collected at slag dirt eliminator place due to the comparatively ambassador's blast reduction of slag dirt eliminator cross section, and residue dust enters dust collecting bag with air-flow.
3, tapping equipment is increased
When perforate, increase horn mouth dust cover, prevent slag dirt from overflowing.
