The specific embodiment
Accompanying drawing 1 is the structural representation of the quick sampler of the utility model deep hole gas; Accompanying drawing 2 is the structural representation of nozzle ring ejector of the quick sampler of the utility model deep hole gas; Accompanying drawing 3 is the binary channels air water tap structure schematic diagram of the quick sampler of the utility model deep hole gas; As shown in the figure, a kind of quick sampler of deep hole gas comprises chisel bit 1, helicoidal pump 2, nozzle ring ejector 3, double-wall drill pipe 4, binary channels air water tap 5, rig 6 and solid and gas eliminator 7 from front to back successively; Described helicoidal pump comprises rotor 21 and stator 22, and rotor 21 front ends are fixedlyed connected with chisel bit 1, and stator 22 front ends are provided with reaming bit 22a; Also comprise joint coupling 8, the rotor 21 of helicoidal pump is all fixedlyed connected with joint coupling 8 front ends with stator 22, nozzle ring ejector 3 is arranged in the joint coupling 8, helicoidal pump 2 is connected with the central through hole of nozzle ring ejector, form circular passage I 9 between the tube wall of nozzle ring ejector and joint coupling, be provided with gas jetting hole 32 between the central through hole of nozzle ring ejector and the circular passage I 9; The tail end of described joint coupling 8 is fixedlyed connected with double-wall drill pipe 4 front ends, and circular passage I 9 is connected with the circular passage II 41 of double-wall drill pipe, and the central passage 42 of double-wall drill pipe is connected with the central through hole of nozzle ring ejector; The tail end of described double-wall drill pipe 4 is fixedlyed connected with binary channels air water tap 5, and two passages of described binary channels air water tap are connected with the circular passage II 41 and the central passage 42 of double-wall drill pipe respectively; Described rig 6 is clamped on the double-wall drill pipe 4; Described solid and gas eliminator 7 is communicated with the passage II 41 of binary channels air water tap 5.In the present embodiment, described nozzle ring ejector 3 comprises body 31, and the tube wall of body 31 is provided with the spray-hole 32 that is used for return air; Pipe 53 and outer tube 54 in described binary channels air water tap 5 comprises, the toroidal cavity 55 of formation one end sealing on the pipe 53 in outer tube 54 is set in, passage I 51 that the tube wall setting of outer tube 54 is connected with toroidal cavity 55 and passage II 52; Described solid and gas material separating device is a strainer.
The concrete grammar that adopts the quick sampler of deep hole gas of the present utility model to take a sample is: when normally creeping into, rig 6 drives pay-off and sampler creeps into forward, the central passage 42 of pressing wind to enter double-wall drill pipe by the passage II 52 of binary channels air water tap 5, pass through the central through hole of nozzle ring ejector then, enter the coal dust that behind the helicoidal pump chisel bit is cut at last and in drilling rod and drill hole wall annular space, blow out.
During sampling, 1 pair of coal body of chisel bit cuts and obtains coal dust, rig 6 normally creeps into, the circular passage II 41 of pressing wind to enter double-wall drill pipe 4 by the passage I 51 of binary channels air water tap 5, enter circular passage I 9 again, form return air through the central passage 42 that enters double-wall drill pipe 4 behind the spray-hole 32 at last, this moment, nozzle ring ejector 3 formed negative pressure near the inner chamber of front end drill bit one side, after coal dust is delivered to the front end cavity of nozzle ring ejector 3 by helicoidal pump, under the traction of negative pressure, enter the central passage 42 of double-wall drill pipe 4, the last solid and gas eliminator 7 that is blown under the effect of return air carries out the solid and gas separation, finishes quick sampling.
Adopt " helicoidal pump-ejector-double-wall drill pipe " three grades of feeding styles, can satisfy the sampling requirement in dark coal seam; Simultaneously, the sampling process continuity is good, and is convenient and swift; And, in the normal drilling process, can carry out air intake control to binary channels air water tap as required, take a sample at any time, realized any location and accurate location; In addition, adopt this system in sampling process, not need shutoff hell, simplified the sampling operation greatly.
What need further specify is, when the sampling distance is more shallow, to be power be delivered to the central passage of double-wall drill pipe in conjunction with helicoidal pump with coal dust to the main negative pressure that produces by the nozzle ring ejector, and coal dust is by pressing wind to be carried into the solid and gas eliminator and carrying out solid and separate and realize sampling fast; When depth selection is dark, by the variable-pitch auger pump under the rotation of drilling rod drives with the coal dust compression and be delivered to ejector, coal dust manage in ejector enters double-wall drill pipe after by pressing wind to be carried into the solid and gas eliminator and carrying out solid and separate and realize quick the sampling.
As to further improvement of this embodiment, described helicoidal pump becomes big variable-pitch propeller pump gradually for pitch from front to back.When depth selection is dark, along with double-wall drill pipe length increases and the return loss of generation air-flow, cause nozzle ring ejector operating efficiency to reduce, even the phenomenon of gas to helicoidal pump one side reflux may appear, the nozzle ring ejector mainly plays a part to reduce the reflux gas amount, reduce reflux gas pressure under this state.At this moment, adopt from front to back pitch to become big variable-pitch propeller pump gradually and carry out feeding, can make coal dust carry out solid at the back-end location of helicoidal pump, offset malleation and spray the spiral of the about 0.25Mpa of spiral chisel bit the coal dust thrust, help coal dust to send into the central passage of double-wall drill pipe smoothly, blow out then.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the power claimed range of the present utility model.
