Abstract
The utility model discloses an underground drill hole orifice dust suppression device which is characterized in that a dust suppression sleeve is arranged on a drill hole orifice; a drill pipe penetrates the dust suppression sleeve along an axial direction; the inside of the dust suppression sleeve is divided by a stopping block into a slag returning area on one side of the drill hole orifice and a dust suppression area on the other side of the drill hole orifice; a slag outlet is arranged at the bottom of the dust suppression sleeve of the slag returning area; a water outlet is arranged at the bottom of the dust suppression sleeve of the dust suppression area; the upper half part of the dust suppression sleeve of the dust suppression area is provided with a spray system; and the tail part of the dust suppression sleeve is provided with an end cover. The underground drill hole orifice dust suppression device can effectively remove the dust at the orifice, so that the dust is prevented from being diffused underground, simultaneously the safety of a drilling constructor can be protected when hole spraying occurs in hole drilling, and the occurrence of major accidents is avoided.
Description
Technical field
The utility model relates to a kind of drilling orifice dust suppression device.
Background technology
Need construction drill in the Coal Production process, the sight line that coal that drilling construction produces and rock dirt not only influence driller when constructing, physically and mentally healthy and that safety causes is very harmful to the miner especially, the latter is the problem that presses for solution.
At present, for the improvement of coal in the drilling construction and rock dirt, be to spray, and together full section spraying is installed in 20 meters scopes, but the dirt effect of going out is not ideal enough at the place, aperture.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of down-hole drilling aperture dust suppression device is provided, so that can more effectively carry out the aperture dedusting, avoid dust to fill the air in the down-hole, improve working environment under the coal mine, guarantee the healthy of worker, guarantee drilling construction personnel's safety, the generation of stopping major accident.
The utility model adopts following technical scheme for the technical solution problem:
The design feature of the utility model down-hole drilling aperture dust suppression device is that the dirt sleeve that goes out is set on drilling orifice, and drilling rod runs through the dirt sleeve that goes out vertically; In the described dirt sleeve that goes out, be divided into the return slag district that is in drilling orifice place one side and the dirt district of going out of opposite side vertically by block; Bottom at the dirt sleeve that goes out in described return slag district is provided with slag notch; Bottom at the dirt sleeve that goes out in the described dirt district of going out is provided with delivery port, at the first half of the dirt sleeve that goes out in the described dirt district of going out spraying system is set, and at the described afterbody that goes out the dirt sleeve end cap is set.
The design feature of the utility model down-hole drilling aperture dust suppression device also is:
Described spraying system is along the spraying ring is set on the circumferencial direction of the dirt sleeve lining that goes out in the described dirt district of going out, each shower nozzle is set on described spraying ring at interval, described spraying ring along the dirt sleeve that goes out axially on be arranged at intervals with multiple tracks, each road spraying ring by main and the snap joint that is arranged on the dirt sleeve outside of going out be communicated with down-hole pressure ventilation pipe and water source tube.
The movable gate of adjustable opening size is set at described slag notch.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model can carry out the aperture dedusting effectively, avoids dust to fill the air in the down-hole, improves working environment under the coal mine, guarantees that the worker is healthy.
2, the utility model can stop that coal, rock particle spray at a high speed, thereby effectively avoid the generation of spray orifice casualty accident for the boring spray orifice phenomenon to occurring in the process of drilling in holing, and guarantees drilling construction personnel's safety, the generation of stopping major accident.
3, the utility model can further improve dust removing effects by multiple tracks spraying ring is set.
4, the utility model is provided with movable gate at slag notch, and the aperture of slag notch can be regulated according to the boring internal return quantity of slag, is convenient to dedusting.
5, the water in the dirt district that can avoid going out of being provided with of the utility model block enters the return slag district and hinders drilling construction, can also effectively avoid drilling rod to damage spraying system in rotary course simultaneously.
6, the utility model is simple in structure, cost is low, easy installation, and is applied widely.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model spraying ring structure schematic diagram.
