Summary of the invention
The purpose of this utility model be to overcome above-mentioned shortcoming and provide a kind ofly control a large amount of dust of drilling and produce in the process in the colliery, fundamentally dustproof, stop dust and be diffused into coal seam in the operating environment dust remover of drilling.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: the coal seam of the present utility model dust remover of drilling, by main body cover, feed pipe, the depositing dust shower nozzle, scum pipe and gutter, soft filter net ring and hard screen pack ring are formed, main body cover is by two section one little one big cylindrical tube, the centre is connected by conical pipe, wherein the great circle column jecket is established scum pipe successively by conical pipe one end, the first road hard screen pack ring, the second road soft filter net ring, feed pipe and gutter, wherein feed pipe is located in the above, the water supply mouth of pipe is divided into the depositing dust shower nozzle, gutter is consistent with scum pipe be located at below.
The above-mentioned coal seam dust remover of drilling, wherein: scum pipe is consistent with axial angle and conical pipe with gutter.
The above-mentioned coal seam dust remover of drilling, wherein: soft filter net ring is with antistatic, fire-retardant rubber material processing.
The above-mentioned coal seam dust remover of drilling, wherein: the first road hard screen pack ring structure comprises the screen pack ring of combining with little soft filter net ring and big hard screen pack ring.
The above-mentioned coal seam dust remover of drilling, wherein: establish 2 or a plurality of screen pack ring according to the ature of coal situation.
During use, when 0.5 meter left and right sides is thrown in boring into, reaming is carried out in boring, when the aperture is expanded to roundlet column jecket diameter, this coal seam dust remover of drilling is enclosed within on the drilling rod, and be fixed on the rib, and then the work of drilling, the dust that produces when drilling directly enters in the main body cover, a large amount of dust are discharged by scum pipe, and the small part dust will be discharged in air by the gap between shell and the drilling rod.Hard screen pack ring at front end will be stopped the graininess dust, force it to discharge by scum pipe, remaining foam shape dust will continue by the gap to effluxing, this part dust is once more by following one soft filter net ring interception, force its can only small part by the gap between shell and the drilling rod, and the passage of dust diffusion this moment has been compressed to minimum cross section, water smoke is moistening to seal this passage with full section because the effect of feed pipe and depositing dust shower nozzle forms to be located at the total space in the second road soft filter net ring outside, make it soluble in water fully, discharge by gutter.Can suitably increase the screen pack ring according to the ature of coal situation, guarantee not have dust and be diffused in the air, the dust impurity of discharging by scum pipe, gutter enters in the water channel, stops the diffusion of dust secondary.
The utility model compared with prior art, as can be known from the above technical solutions, the coal seam of the present utility model dust remover of drilling is a kind of a large amount of dust that coal mining is drilled and produced in the process of controlling, and is fundamentally dustproof, stops dust and is diffused into coal seam in the operating environment dust remover of drilling.
The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
