Description

Air drill pore-forming and creep into cleaner
Technical field
The invention belongs to mechanical field, particularly a kind of cleaner that is applicable in the drilling construction process of lithostratigraphy.
Background technology
Along with the further attention of country to the stone cultural artifact Protection, the scope of historical relic's protection work and dynamics all further increase.One of conventional means that anchoring is protected as stone cultural artifact is deposited rock mass in the historical relic tax and is widely used.Rig can be divided into air drill, electric drill, hydraulic drill, and air drill is most widely used at the Anchor cable-rod pore-forming.To produce a large amount of dirt slags among the perforate of air drill and the drilling process.Dust can be floating more than 1 kilometer, and is larger to the workers ' health infringement of being engaged in construction; To the scenic spot open and visitor's visit has a negative impact; Dust drops on the historical relic body surface also can produce pollution to the 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.Existing patent is that number of patent application is the utility model patent " a kind of environmental protection dust collector " of " 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 the constructor is caused certain injury, if construct near the historical relic body, still to a certain extent the historical relic body is produced and pollutes;
2, slag dirt enters dust remover by bounce-back, Speed Reduction after the bounce-back, and the effect that enters dust remover is bad, and does not carry out slag dirt and separate, often owing to dust elimination freely is not forced to stop the work of creeping into;
3, there is not perforate dedusting relevant device.
Summary of the invention
The purpose 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 is collected device, described deduster is provided with streamlined threeway, the afterbody of described streamlined threeway is connected with described dust and collects device, be provided with dynamic sealing device and static seal device in the described deduster, described dynamic sealing device comprises the two-layer at least active blade that is enclosed within on the drilling rod, described active blade be an aperture greater than circular of drill pipe diameter, but described static seal device is the medium that is arranged on the dust adsorption of deduster afterbody.
Described active blade is two-layer, be respectively the first active blade and the second active blade, described the first active blade and the second active blade are successively set on the afterbody of drilling rod, the lower end of described the first active blade and the second active blade contacts with the inwall of deduster, be provided with nut before described the first active blade, be provided with baffle plate behind described the first active blade; Described the second active blade is arranged on the tail end of deduster, is provided with the afterbody nut before described the second active blade; Be provided with described static seal device between described the 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 the 3rd active blade is arranged on the front side of the streamlined baffle plate in the described streamlined threeway.
The aperture of described active blade is greater than drill pipe diameter 6mm~10mm.
But the described medium that is arranged on the dust adsorption of deduster afterbody is sponge.
As another improvement of the present invention, described streamlined threeway and dust are collected between the device and are provided with slag dirt eliminator.
As another improvement of the present invention, be provided with the horn mouth dust cover at the deduster opening part.
The invention has the beneficial effects as follows:
1, increases deduster drilling rod seal approach.
Adopt three layers of active blade 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 the two-layer active blade forms static seal.Adopt movable sealing and static seal to think the sealing means of combination, good sealing effect.
2, improve slag dirt guidance mode and processing mode.
Adopt streamlined threeway guiding dust to enter slag dirt eliminator.Slag dirt guiding port adopts streamlined baffle plate, and guiding slag dirt enters slag dirt eliminator with air-flow, the guiding better effects if.Slag dirt eliminator is set, slag dirt enters slag dirt eliminator along streamlined baffle plate from the instrument lower passage, its principle is that rock slag and part dust are collected at slag dirt eliminator place because slag dirt eliminator cross section reduces than ambassador's blast, and the residue dust enters the dust collecting bag with air-flow.
3, increase tapping equipment
When perforate, increase the horn mouth dust cover, prevent that slag dirt from overflowing.
