Abstract

The utility model discloses a drill dust remover which comprises a dust removing guide pipe 1, a dust suppression chamber 3 and a dust collection box 4; wherein, the dust removing guide pipe 1 is fixedly connected with the rear part of the dust suppression chamber 3, the dust removing guide pipe 1 is communicated with the dust suppression chamber 3, and the outlet of the dust suppression chamber 3 is extended into the dust collection 4; the drilling inlet 7 of the dust removing guide pipe 1 is sealed by a sealing piece 6, and spraying devices 5 are respectively arranged on the lateral wall of the dust suppression chamber 3 and the dust collection box 4. The drill dust remover has simple structure, easy manufacturing and use, good dust removal effect and saves resources.

Description

The rig deduster

Technical field

Supporting dust arrester when the utility model relates to a kind of boring.

Background technology

On July 18th, 2007, the CN2923985Y China utility model manual of bulletin disclosed a kind of boring dust arrester, this dust arrester comprises a dust arrester with airtight inner chamber, control of dust funnel, dust discharge pipeline, gives water ring and jet pump, during work, the suction that produces by jet pump with dust suck from the space between dust arrester and the drilling rod dust arrester then through the control of dust funnel to the dust discharge pipeline, in the dust discharge pipeline, forms behind mud ball or the mud in the inflow collecting vessel by water that injects to water ring and mix dust.But this apparatus structure complexity, the cost of manufacture height, and because this device is with water filling mixing dust, therefore very big to the waste of water resource.

The utility model content

It is a kind of simple in structure that the purpose of this utility model is to provide, the dust arrester of good dedusting effect.

The technical solution of the utility model is: rig deduster of the present invention, comprise dust removal pipe 1, the dirt chamber 3 of going out, connect dirt case 4, dust removal pipe 1 is fixedly connected on 3 rear portions, dirt chamber of going out, dust removal pipe 1 is communicated with between the dirt chamber 3 with going out, the outlet of dirt chamber 3 of going out extend into and connects in the dirt case 4, dust removal pipe 1 go into to bore mouthful 7 usefulness seals, 6 sealings, on go out dirt chamber 3 and the sidewall that connects dirt case 4, all be installed with can water spray atomization mechanism 5.

The above-mentioned spout that is installed on the atomization mechanism 5 on dirt chamber 3 sidewalls that go out is positioned at dirt chamber 3 radial midpoint of going out, and the spout direction connects dirt case 4 along the dirt chamber 3 of going out towards the below.

Above-mentioned be installed on the spout direction that connects the atomization mechanism 5 on dirt case 4 sidewalls along the dirt chamber 3 of going out radially towards the exit position of the dirt chamber 3 of going out.

First going out to bore and mouthful insert the coal seam and sealing around outer rim during use with dust removal pipe 1, mouthful mouth that goes out to bore through dust removal pipe 1 of going into to bore that drilling rod 2 penetrates dust removal pipe 1 pierces the coal seam, dust rotates under the blast effect that produces at a high speed at drilling rod 2 and sprays the space between drilling rod 2 and dust removal pipe 1, because 7 sealed 6 in the mouth of going into to bore of dust removal pipe 1 seals, dust can only enter the dirt chamber 3 of going out by favorable current, the atomization mechanism 5 that goes out on the dirt chamber 3 is sprayed simultaneously, after the dust water smoke that atomization mechanism 5 produces on the dirt chamber through going out is moistening rapidly precipitation fall into and connect dirt case 3, fly away no longer everywhere, if once Pen Wu the dirt effect of going out is not ideal enough, the also available atomization mechanism 5 that connects on the dirt case 3 carries out the secondary dirt that goes out, to reach dust removing effects.The utility model not only saved water resource greatly, and structure is simpler because of having adopted atomization mechanism, and is easy to process.Carry out final dusting because two cover atomization mechanisms have been installed, dust removing effects reaches more than 70%, has improved operating environment, has ensured worker's physical and mental health.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

As shown in drawings, the utility model comprises dust removal pipe 1, the dirt chamber 3 of going out, connect dirt case 4 and atomization mechanism 5, the dust removal pipe 1 and the dirt chamber 3 of going out are all the pipe shape, its diameter is greater than the diameter of drilling rod 2, mouthful 7 usefulness seals 6 of going into to bore of dust removal pipe 1 seal, the outer rim of seal 6 excessively cooperates with the internal diameter of dust removal pipe 1, the internal diameter of seal 6 is identical with the diameter of drilling rod 2, the rear portion of dust removal pipe 1 is communicated with the dirt chamber 3 of going out, dust removal pipe 1 is fixedlyed connected with the dirt chamber 3 of going out, the atomization mechanism 5 of energy water spray is installed on the middle part sidewall of dirt chamber 3 that goes out, the spout direction of this atomization mechanism 5 is towards connecing dirt case 4, the outlet of dirt chamber 3 of going out is communicated to and connects in the dirt case 4, connect on dirt case 4 sidewalls atomization mechanism 5 be installed equally, the spout direction of this atomization mechanism 5 along the dirt chamber 3 of going out radially towards the exit position of the dirt chamber 3 of going out.During use, the mouth that goes out to bore of dust removal pipe 1 gos deep into the coal seam, and sealing around its outer rim, drilling rod 2 penetrates through the mouth of going into to bore of dust removal pipe 1, creep into the coal seam from going out to bore mouth, dust is injected to the dust removal pipe 1 from drilling rod 2 and the space that dust removal pipe 1 goes out to bore between the mouth under the effect of the blast that produces of rotation at a high speed because of drilling rod 2,7 sealed 6 sealings of going into to hole because of dust removal pipe 1, dust enters the dirt chamber 3 of going out along the connected entrance of the dust removal pipe 1 and the dirt chamber 3 of going out, atomization mechanism 5 begins water sprays simultaneously, dust is fallen rapidly after heavy because of the moistening change of water smoke and is connect dirt case 4, if dust is excessive, the one-time dedusting effect is bad, can open the atomization mechanism 5 that connects installation on the dirt case 4 and carry out final dusting, so just can eliminate dust substantially.
