Embodiment one

One kind of the present embodiment is drilled Four proofings apparatus, including the gentle slag separator of orifice sleeve device, dust-extraction unit；It bores The drill rod sleeve man-hole opening casing bit of machine, the orifice sleeve device is for separating big bastard coal, small bastard coal and dust, institute State orifice sleeve device output port and dust-extraction unit slag input end connect, the dust-extraction unit be used for the small bastard coal of dust-laden into The output port of row preliminary dust removal deslagging, the dust-extraction unit is connect with gas-slag separation device, and the gas-slag separation device is used for Final dusting deslagging is carried out to the dust that dust-extraction unit does not exclude.

As shown in Figures 1 to 4, the orifice sleeve device includes quadrangle box 101, extension 102, the first scum pipe 103 and second scum pipe 104, the top surface of the quadrangle box 101 be fixedly connected by flange 105 with extension 102, extension 102 by drill sleeve wherein, prevent Four proofings apparatus from deviateing in the process of drilling, cause equipment damage；First scum pipe 103 and second scum pipe 104 be oppositely arranged on the side of quadrangle box 101；First scum pipe 103 is for being discharged big coal Cash, shape are hollow cylinder, are vertically mounted on the side of quadrangle box 101；Second scum pipe 104 is for being discharged small coal Cash and dust, shape are the small hollow round table of the big mouth of tail, are tiltedly mounted on the another side of quadrangle box 101.The rectangular box The bottom surface of body 101 is hinged at quadrangle box 101, retractable, installs a block baffle on the bottom surface of the quadrangle box 101 106；First circular hole 107 for being used to be set with drilling rod is respectively opened up on the bottom surface of the quadrangle box 101 and baffle 106, the The diameter of one circular hole 107 is more bigger than the diameter of drilling rod；It is provided between the bottom surface and baffle 106 of the quadrangle box 101 close Packing 108, the gasket 108 can use waste and old belt, opened up on the gasket 108 one it is equal with drill pipe diameter Second circular hole 109 not will cause dust and leak, it is preferable that institute to keep drilling rod closed when being inserted into orifice sleeve device Stating gasket 108 is three-decker, successively big laying by size, to obtain better seal effect.

As shown in Figures 5 to 9, the dust-extraction unit includes altar type main body 201, the first mud hole 202, slag input hole upper cover 203 and first triple valve 204；The altar type main body 201 it is outer shaped like wine jar shape necking pipe, the lower part of the altar type main body 201 It is connect by flange 105 with gas-slag separation device, the dust not being excluded is made to enter gas-slag separation device, the altar type main body 201 top is connect with slag input hole upper cover 203, and the shape of slag input hole upper cover 203 is the small hollow round table of the big mouth of tail, described Slag input hole upper cover 203 is welded and fixed with the second scum pipe 104, for receiving the small bastard coal and powder that are discharged from orifice sleeve device Dirt, first mud hole 202 and the first triple valve 204 are oppositely arranged on the two sides of altar type main body 201, by the first threeway Air hose and water pipe are connected on valve 204 by hydraulic pressure into water mist, first mud hole of the small bastard coal and part dust to entrance from side 202 by pressing wind to go out；The dust-extraction unit further includes the oblique flow distribution plate 205 being arranged in inside altar type main body 201, flow distribution plate Effect is stopped big bastard coal, prevents it from entering gas-slag separation device.

As shown in Figure 10 to Figure 12, the gas-slag separation device includes reducer pipe 301, the second triple valve 302, slag feed pipe 303 and separating mechanism；303 oblique weld of slag feed pipe is in the upper end of reducer pipe 301, and the altar type main body with dust-extraction unit 201 lower end is connected by flange 105, and second triple valve 302 is bolted on the top of reducer pipe 301, described The bottom of reducer pipe 301 is arranged in separating mechanism.Second triple valve 302 is mainly used to air hose and water pipe line and variable diameter Pipe 301 is attached, and forms negative pressure by wind pressure and the dust for generation of drilling in orifice sleeve device is sucked dust-extraction unit and gas In slag separator.The separating mechanism includes 306, two gas vents 304 of cavity and second mud hole 305, the row Stomata 304 and the second mud hole 305 are welded on cavity 306, and described two gas vents 304 are located at the upper of the second mud hole 305 The reason of at square 3cm, second mud hole 305 is concordant with bottom plate, welds in this way is to prevent during deslagging, and slag can be from It is discharged simultaneously in three holes, and the second mud hole 305 slag heap in gas-slag separation device that is also possible to prevent concordant with bottom plate manufactures The concordant deslagging simultaneously of Cheng Sankong causes three hole plugs.The reducer pipe 301 passes through nozzle gradual change by the straight tube of different thicknesses Mode is welded, and so that the wind pressure entered is generated variation to make the dust entered more fill by the big welding manner of pipe diameter size That divides mixes with water mist, achievees the purpose that reduce dust.

Working principle is as follows:

The present embodiment be mainly by wind pressure generate negative pressure to coal (rock) dirt that generates drilling machine in boring procedure with The larger spoil (coal cinder) generated is separated, and reduction is reached by three devices and is drilled bring dust.First is hole Muzzle pipe device, by by drill rod sleeve man-hole opening casing bit make drilling generate bastard coal enter the device in, big bastard coal from The discharge of first scum pipe 103, small bastard coal and dust by the negative pressure that wind pressure generates enter down together in device, that is, dust-extraction unit, Dust is reduced by the water mist sprayed from the first triple valve 204 in dust-extraction unit, by first mud hole 202 on opposite to small coal Cash is purged.Remaining dust enters third device i.e. gas-slag separation device by negative pressure, and gas-slag separation device passes through wind Dust is sucked the device by the negative pressure that pressure generates, and fills the water to form water mist and inhale the dust sucked in by pressure wind and water pipe It receives, changing wind pressure intensity by reducer pipe 301 makes water mist pressure reduction to generate water flow.Row is equipped in 301 bottom of reducer pipe Stomata 304 and the second mud hole 305, water, slag and aerosol are efficiently separated, and the gas of extraction are taken away by lower negative pressure pipe, water Slag is then discharged along the second mud hole 305, effectively improves the working environment and security context of construction site.

The inconvenience of coal (cash) dirt bring and harm generated when drilling greatly reduces in the Four proofings apparatus of drilling, and makes work Personnel no longer cause relevant disease during drilling because dust is excessive, and this set Four proofings apparatus is prominent in fire prevention, gas prevention Out, anti-spray orifice etc. also has certain effect, so that the safety coefficient that underground is drilled greatly improves, the life security of personnel Also it can preferably be ensured.And because efficiency and qualification rate that the reduction of dust is drilled also have a certain upgrade.

The above-mentioned description to embodiment is for that can understand and apply this practical convenient for those skilled in the art It is novel.Person skilled in the art obviously easily can make various modifications to these embodiments, and illustrating herein General Principle be applied in other embodiments without having to go through creative labor.Therefore, those skilled in the art are according to this The announcement of utility model, does not depart from improvement that the utility model scope is made and modification all should be in the protection of the utility model Within the scope of.
