Embodiment 1
[0044] Embodiment 1: a kind of air jet dust collector for mine drilling, such as figure 1 As shown, it includes in turn the expansion type anti-spray dust collection pipe 4, the composite dust collection cover 1 with anti-spray holes, the dust delivery pipe 15, the atomization dust removal chamber 5, the jet pipe 2 and the gas collector 3, all of which are welded by stainless steel plates , has good corrosion resistance, and the equipment has the advantages of light weight, high strength, not easy to damage, and long service life.
[0045] Such as figure 1 and 3 As shown, the end of the expansion type anti-spray dust collection pipe 4 extending into the borehole is a gas inlet 45, and the end of the expansion type anti-spray dust collection pipe 4 near the gas inlet 45 is sleeved with a stainless steel pipe 41, the stainless steel pipe 41 is sealed and welded on the outer pipe wall of the expansion type spray-proof dust collecting pipe 4 at one end away from the gas inlet 45...
specific Embodiment approach
[0057] Specific implementation method: when the operator uses it, first use a drilling machine to initially drill holes, then take out the drill pipe, place the expansion type anti-spray dust collection pipe 4 in the drill hole, and then place the expansion type anti-spray dust collection pipe 4 4 The end close to the water pipe 44 is connected to the drill pipe outlet 13 of the blowout hole composite dust collection cover 1, and the air inlet pipe 2 543 of the atomizing dust removal pipe is connected to the blowout hole composite dust collection cover 1 through the dust delivery pipe 15 , and then through the threaded rod 55 or snap piece 16 and hook 165, the atomizing dedusting chamber 5, the jet pipe 2 and the gas collector 3 are quickly connected in sequence, and the jet pipe 2 is connected to the gas collector 3 through the snap piece 16 and the hook 165. The high-pressure gas delivery pipe 21 is connected, and the air jet dust collector for this kind of mine drilling can ...
Embodiment 2
[0061] Embodiment 2: a kind of air jet dust collector for mine drilling, such as Figure 12 As shown, the difference from Example 1 is that the opening direction of the coal dust discharge pipe 17 is perpendicular to the blowout hole composite dust collection cover 1, and this kind of blowout hole composite dust collection can be used except for drilling at a large elevation angle. When the cover 1 is used for drilling in a nearly horizontal direction, the coal dust discharge pipe 17 is made vertically downward or obliquely downward by rotating the anti-spout hole composite dust suction cover 1, which is convenient for large particles of coal dust to be naturally discharged under the action of gravity. Slip, and can not accumulate in coal dust discharge pipe 17.
