Description
Technical field
Originally belong to the coal mining technical field, relate in particular to the packing of a kind of mining air water slag and separator.
Background technology
Coal mine gas, dust accident are one of great disasters of down-hole, and workman's life security is caused a significant threat.Cause the basic reason of this phenomenon to be, before exploitation topping coal seam, must wear a layer extraction to projecting coal bed gas pressure relief at the shallow drill site in heading top or middle deep drilling field; Execute being drilled in when wearing the coal seam, the high pressure gas in the coal seam pours out along boring under the stirring of rig moment, and the limited air quantity of local ventilation effective dilution gas when being difficult in gas moment ejection, thereby cause drill site zone gas bearing capacity frequently to transfinite.
Therefore, be necessary very much to develop a kind of air water slag separator at the problem of transfiniting that the boring procedure of gas extraction hole occurs, gas, boring mud and water that boring procedure is produced effectively separate, then gas is collected and stored, thereby that avoids gas to leak causing transfinites, and the harm that brings of boring mud and waste water bulk deposition.
Notification number be Chinese patent that CN 102337920A, name are called gas dust packing device disclose a kind of can be to the gas of ejection in the boring in the extraction borehole work progress and the gas dust packing device of pressing wind row powder dust carry out effective packing, this packing device adopts the capsule expansion to carry out sealing of hole, the capsule fixture is various, thereby cause the device heaviness, and, this packing device can only carry out packing with gas and can not separate dust, and is very inconvenient in actual applications.
Notification number is that Chinese patent that CN 202250163U, name are called gas drainage under suction air water pulp separator discloses a kind of gas drainage under suction air water pulp separator that the air water slag that boring is discharged is separated of being mainly used in, but this eliminator does not have air water slag packing function, must be used by gentle grain slag packing device, thereby cause using inconvenience.
The utility model content
At the deficiency that prior art exists, the utility model provides a kind of reliable and effective, simple in structure, the packing of gas collection grain slag and the packing of mining air water slag and the separator that separate one.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

Slide to the grain slag separator tube in order to ensure boring mud under can be smooth and easy in sleeve, also accommodate spirality deslagging assembly for deslagging in sleeve inner, spirality deslagging assembly is positioned at the space of sleeve lining and drilling-rod external wall formation and around drilling rod, an end of spirality deslagging assembly is fixed on the drilling rod.
Described spirality deslagging assembly is the spirality iron wire, and its diameter is half of difference of sleeve and drilling rod radius.
Semiclosed end to the openend of described spirality deslagging assembly sleeve is pressed close to sleeve lining gradually until contacting with sleeve lining.
For leaking of air water slag in preventing from holing, guarantee that the air water slag can enter sleeve and can not enter the tunnel by boring, the face towards the sleeve openings end of said fixing flange is provided with the elasticity sealing of hole assembly that closely centers on sleeve, is used for forming confined space in the feasible boring.
Described elasticity sealing of hole assembly is the taper shape of hollow, sleeve can be just in time from the cavity of elasticity sealing of hole assembly pass with, sleeve outer wall closely contacts with elasticity sealing of hole assembly.
Above-mentioned air extractor is the drawing-in type pump.
The semiclosed end of above-mentioned sleeve inner fixedly has the sealing ring that closely contacts with drilling rod, enters the tunnel in order to prevent the air water slag from the sleeve bottom.
The operating principle of the utility model device is as follows:
In the drilling construction process, when boring mud, waste water and methane gas are sprayed by boring, owing to sleeve outer wall contacts with drill hole wall, and because the sealing of hole effect of elasticity sealing of hole assembly, the air water slag enters sleeve and can not enter the tunnel by boring.The rotation of drilling rod drives spirality deslagging assembly and rotates, and boring mud is smooth and easy downslide under the rotation of spirality deslagging assembly.When the air water slag arrived the cover tube bottom, the air extractor that is installed on the stack was discharged the gas tube that enters in the tunnel with methane gas by stack; Grain slag enters the grain slag separator tube, and waste water flow to from the filter bores on the inner pipe wall and enters outer tube, and discharges by gutter, and the boring mud in being retained in the pipe is discharged by outer tube.Thereby the air water slag by the boring ejection is effectively separated.
Compared with prior art, the utlity model has following characteristics:
1, the utility model unites two into one the packing of air water slag with separating, be applicable to that the air water slag to ejection in holing carries out packing and effectively separates in the coal mining drilling construction, gas exceeding limit and the dust harzard that can avoid in the drilling construction gas, boring mud and waste water by the boring ejection to cause, and boring mud and waste water bulk deposition can greatly satisfy the requirement of safety of coal mines exploitation to the pollution of tunnel environment.
2, the utility model adopts fixed flange as fixation kit, has advantages such as simple in structure, in light weight.
3, the utility model adopts and in sleeve inner spirality deslagging assembly to be set, and drives spirality deslagging assembly when drilling rod rotates and rotates, and boring mud slides to the grain slag separator tube under can be smooth and easy under the rotation of spirality deslagging assembly, prevent that boring mud from accumulating in the sleeve.
