Abstract
The utility model relates to a de-dusting device, especially to a de-dusting device for drilling of coal mines. A high-pressure shower nozzle and a drainage joint are fixed on the right of a de-dusting pipe; the nozzle of the high-pressure shower nozzle is arranged on the upper portion in the de-dusting pipe; the de-dusting pipe on the left of the high-pressure shower nozzle is wound and fixed at a drilling hole with a hemp rope; the high-pressure shower nozzle is communicated with a high-pressure water pump through a high-pressure hose; the drainage joint is communicated with the bottom in the de-dusting pipe; the drainage joint is communicated with a water tank from which the water flows into a sedimentation tank through a flow guide pipe. The de-dusting device has the advantages of simple structure and good de-dusting effect and enables the environment around a drilling position to be clean and healthful.
Description
Technical field
The present invention relates to the dust arrester that a kind of dust arrester, particularly colliery are drilled.
Background technology
The dust arrester that uses of drilling now mainly is that one group of sprayer is installed near the aperture, in the process of drilling, opens sprayer and carries out depositing dust, but there is spacing in spraying with the aperture, a large amount of dust escape out with gases at high pressure, cause near the visibility of drill carriage lower, and personnel breathe difficulty.And the water yield that atomizing de-dusting equipment sprays out is larger, and can't converge collection, carries out production strictly in line with rules and regulations to the tunnel and brings considerable influence.The hydraulic slag discharging of employing technique is also arranged, although can administer the dust of drilling and producing from the source, exist because hydraulic action causes the problem in the hole of collapsing, affect into porosity.Adopt in addition the method for Dust collecting net being installed in the drill site and purifying distinguished and admirable water curtain, can only slightly improve the outer air ambient of drill site, the personnel in the drill site, machine, equipment etc. still are subject to the harm of dust.The tradition cleaner of drilling is accompanied with electric power or oil hydraulic system, and equipment is too fat to move, and volume is large, weight is large is inconvenient to transport, and installs, safeguards complicated, and exists and loses the potential safety hazards such as quick-fried.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of dust arrester of drilling, it is simple in structure, good dedusting effect, the clean clean health of drill site surrounding environment.
The present invention solves the technical scheme that its technical problem takes: the right side of dust removing tube is high-pressure nozzle and drainage joint fixedly; The spout of described high-pressure nozzle is at the dust removing tube internal upper part, and the dust removing tube in high-pressure nozzle left side is fixed on hell with the rope made of hemp, and described high-pressure nozzle communicates with high-pressure hydraulic pump by high-pressure hose; Described drainage joint communicates with the dust removing tube inner bottom part, and drainage joint communicates with the tank that flows into sedimentation basin by mozzle.
1), owing to adopt the dust removing tube structure the present invention has following advantages:, the whole process of atomizing de-dusting is all carried out in the hole, has effectively controlled dust and has escaped, and has both drawn the advantage of hydraulic slag discharging dedusting, overcome again the drawback in the hole of collapsing, reached the purpose of producing the dirt that goes out in dirt, the hole in the hole.2), because the design of multiple tracks annular water curtain is adopted in spraying, realized all standing around the tube wall, and water smoke and current acting in conjunction, the effective dust in the inner high voltage air-flow of enrichment hole, can stop secondary to produce dirt by moistening drilling cuttings again, dust reduction rate is significantly improved, dust reduction rate reaches more than 90%.3), owing to adopt and in orifice tube, to focus on flying dust, prevented that so namely the spraying current from entering the phenomenon that plug-hole occurs in boring with drilling rod, the gas preventing and control the when while also is conducive to drill hole spray.4), dust removing effects is obvious, directly at dust removing tube internal spraying depositing dust, treating flour dust in the source, than Dust collecting net being installed in the tunnel and being purified distinguished and admirable water curtain good dedusting effect.5), water supply volume can according to circumstances rationally regulate, the sewage of discharging simultaneously converges by mozzle, and recycles through precipitation, has reduced to greatest extent water supply volume, and has realized sewage zero-discharge.6), with respect to the cleaner of drilling on the market, this device has pure frame for movement, does not relate to electric fixtures, do not have the advantages such as Explosion-Proof without power supply, and fixture is few, simple in structure, lightweight, volume is little, installation and transportation are convenient, efficient is high, very easily promotes and uses.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing and example.
Fig. 1 is front view of the present invention;
Fig. 2 is right view of the present invention;
Fig. 3 is that the present invention uses state reference map.
The specific embodiment
As shown in Figure 1, 2, fixedly high-pressure nozzle 3 and drainage joint 7 of the right side of dust removing tube 4; The shower nozzle of described high-pressure nozzle 3 twines the rope made of hemp 1 at dust removing tube 4 internal upper parts on dust removing tube 4 external cylindrical surfaces in high-pressure nozzle 3 left sides, described high-pressure nozzle 3 communicates with high-pressure hydraulic pump (not shown in FIG.) by high-pressure hose 2; Described drainage joint 7 communicates with dust removing tube 4 inner bottom parts, and drainage joint 7 communicates with the tank (not shown in FIG.) that flows into sedimentation basin by mozzle 8.
Described high-pressure nozzle 3 has two rows, uniform 3 shower nozzles of every row.
Described high-pressure nozzle 3 is radially fixing along dust removing tube 4.
Fixing elastic wear-resisting water shutoff cover 5 on the right side of described dust removing tube 4, elastic wear-resisting water shutoff cover 5 has the centre bore 6 that is a bit larger tham bit diameter.
The below illustrates, and is Φ 113mm bit bore with diameter for example.
As shown in Figure 3, before the drilling construction, first according to design angle with the perforate of Φ 133mm drill bit, hole depth 2m has an end of the rope made of hemp to push in the hole dust removing tube 4, and with the tight sealing of hole of yellow mud.High-pressure hose 2 and high-pressure hydraulic pump are connected.
Change Φ 113mm drill bit and can begin to creep into operation.When rig starts, open high-pressure hydraulic pump, the drilling cuttings of discharging in the hole and coal dust are behind the scenes through the annular spray water that first row high-pressure nozzle 3 forms, dust major part in the high pressure draught settles down, drilling cuttings is whole moistening one-tenth coal slimes also, stoped the drilling cuttings secondary to produce dirt, water, dust, drilling cuttings mixture are along with High-Pressure Water washes away mozzle 8 to the bottom.Air-flow purifies once more through the annular spray water backstage that second row high-pressure nozzle 3 forms in the hole, this moment from dust removing tube 4 discharge distinguished and admirable dust substantially all tackle and sedimentation.
Coal slime, the sewage of discharging from mozzle 8 are used by tank and are caused sedimentation basin, and water can reuse after precipitation.
