Abstract

The utility model disclosing a borehole dust remover is characterized in that: an entering tube with a through drill pipe inside is arranged at the front side of a dust collector, a backboard processed with a entering borehole is arranged at the back side of the dust collector, The lower end of the dust collector is connected with the upper end of a dust collecting filler, the lower end of the dust collecting filler is connected to a dust removing pipe, a water supplying ring connected with a water pipe is arranged by the external wall at the middle part of the dust removing pipe, a water inlet is arranged on the dust removing pipe at the section surrounded by the water supply ring, the lower end of the dust removing pipe is connected with a jet pump. During operation, the drill pipe is arranged through the borehole on the backboard, then through the entering tube of the dust collector and drills into rock stratum. Drill dust generated by rock drilling goes into the cavity of the dust collector through an interval between the entering tube inner wall and the drill pipe, drill dust is absorbed into the jet pump by suction and transported by the dust collecting filler, and mixes with water from the water inlet in the dust removing pipe, generated mud ball or slurry from the mixture is ejected into a dust collecting barrel at the bottom end of the jet pump. The utility model can collect and remove the dust and rock scrap of drilling together and realizes dustless drilling.

Description

The boring dust arrester
One, technical field
The utility model belongs to the building implement technical field, matching used dust arrester when being specifically related to a kind of boring.
Two, background technology
At present, use Churn drill to hole at rock-soil layer in construction work, all adopt the air flushing deslagging, landwaste will be gone out the aperture with compressed air.Do not taking under any measure that prevents dust diffusion, a large amount of drilling cuttings dust of generation can spread in the ambient air, cause the dust content severe overweight, and cause the dust pollution in hundred meters scopes.Grievous injury health and surrounding environment.In order to change this situation, people adopt water curtain to catch methods such as dirt, vacuum cleaner dedusting, but all have shortcomings such as weak effect, water supply volume is big, equipment investment is big.
Three, summary of the invention
The purpose of this utility model provides a kind of boring dust arrester of simple in structure, reasonable in design, good dustproof effect.
For achieving the above object, the technical solution adopted in the utility model is: comprise dust arrester, control of dust funnel, dust discharge pipeline and jet pump with airtight inner chamber; In having, the installed in front of dust arrester wears the hand-hole pipe of drilling rod, its rear side is installed the backboard that has into boring, the dust arrester lower end links to each other with control of dust funnel upper end, control of dust funnel lower end connects the dust discharge pipeline, on the lateral wall of dust discharge pipeline middle part, be equipped with the water ring of giving that links to each other with water pipe, the part dust discharge pipeline that surrounds to water ring is provided with water injection hole, and the lower end of dust discharge pipeline connects jet pump.
Adopt said structure, during use, with the boring of tubular alloy bit, swathe packing cloth in hand-hole pipe periphery then and insert boring earlier, make sealing between hand-hole pipe and the boring.The go into boring of drilling rod from the backboard is pierced into through dust arrester, hand-hole pipe and is stretched to the rock stratum.Drill bit creeps into drilling cuttings dust that the rock stratum produces from the space between hand-hole inside pipe wall and the drilling rod, enter the dust arrester inner chamber, under the suction of jet pump,, after forming mud ball or mud oar, the water that dust discharge pipeline and water injection hole inject is discharged in the residue collecting vessel by the control of dust funnel from the lower end of jet pump.The utility model can all collect the landwaste dust that boring is discharged to concentrate to be got rid of, and realizes that no dust creeps into.And having simple in structurely, volume is little, in light weight, is easy to carry advantages such as low cost of manufacture.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment
As shown in drawings, the utility model comprises dust arrester 4, control of dust funnel 17, dust discharge pipeline 18 and jet pump 24; Dust arrester 4 is airtight columnar structured of inner chamber, wears the long tubular hand-hole pipe 2 of drilling rod 3 in its installed in front has, and the rear end of hand-hole pipe 2 communicates with dust arrester 4 inner chambers.The internal diameter of hand-hole pipe 2 is bigger than the diameter of drilling rod 3, forms big gap between drilling rod 3 and hand-hole pipe 2 inwalls so that make, and is convenient to the landwaste dust and discharges.The outer end of the short tube 1 of the rear side of dust arrester 4 is provided with backboard 9.Backboard 9 can be made of rubber tile, and what have in the middle that drilling rod 3 penetrates goes into boring 16, and aperture is identical with drilling rod 3 diameters.Backboard 9 also also can adopt other material to constitute, and is going on boring 16 peripheries internal diameter and the identical rubber seal of drilling rod 3 diameters are installed.The edge of going into boring 16 in the above-mentioned dual mode all fits tightly with drilling rod 3 surfaces, thereby realizes that drilling rod 3 has better seal when rotating.Backboard 9 is to be fixed on the junction plate 13 of dust arrester 4 rear side short tubes 1 end by elastic fixing clip 14, and the two is fitted closely, prevents that the landwaste dust from revealing.In order to improve dust collecting effect, in the inside of dust arrester 4 middle baffle plate 5 can be installed, middle plate washer 5 is to be made of fixed dam 8, door bolt plate 6 and the rubber gasket sheet between the two 7.Fixedly plate washer 8 is the square plates on dust arrester 4 inwalls, the centre has the circular hole that passes through for drilling rod 3, its dual-side near dust arrester 4 sidewalls is provided with the T-slot that door bolt plate 6 can be installed, in the middle crack of door bolt plate 6 and fixed dam 8, be equipped with that internal diameter is identical with drilling rod 3 diameters, external diameter is greater than the ring-shaped rubber sealing plate 7 of fixed stop 8 circular holes.During work, rubber gasket sheet 7 just is enclosed within drilling rod 3 outsides, and along with drilling rod 3 rotates, realizes rotary seal.The effect of middle baffle plate 5 is to constitute the barrier wall that stops landwaste to be gone out to the back-end together, after the landwaste of ejection bump against middle baffle plate 5 in the hand-hole pipe 2 with air-flow, change direction after, concentrate and fall in the control of dust funnel 17.Dust arrester 4 lower ends link to each other with control of dust funnel 17 upper ends, and the lower end of control of dust funnel 17 is connected with dust discharge pipeline 18.Dust discharge pipeline 18 can be made up of upper and lower two parts, in the middle of upper and lower dust discharge pipeline 18, install link to each other with water pipe 10 give water ring 20, be equipped with the core pipe 19 of being with water injection hole 21 in it, core pipe 19 communicates with upper and lower dust discharge pipeline 18.Dust discharge pipeline 18 can use flexible pipe up and down.The lower end of following dust discharge pipeline 18 is connected with jet pump 24.Jet pump 24 is brought the high pressure chest 22 of airduct 23, the conical nozzle 25 at middle part and the mixing chamber 11 of bottom into by top and is constituted.Mixing chamber leads to residue collecting vessel 15 through the trunnion 12 of lower end.Its operating principle is: when pressure-air when air inlet port 23 and high pressure chest 22 enter nozzle 25, because nozzle 25 inner chambers are tapered, and outlet diameter is less, high pressure draught is injected mixing chamber 11 at a high speed, cause around the nozzle 25 and formation negative pressure in the mixing chamber 11, the water that landwaste dust in the control of dust funnel 17 and water injection hole 21 inject is drawn onto in the mixing chamber, be mixed into mud ball or mud after, under action of inertia, be discharged in the residue collecting vessel 15.
