The goaf sampler that the utility model provides replaces manually sampling by air driven pump is set, and guarantees the true and reliable of sample gas by moisture trap is set, and utilizes wind energy as power source, reaches safe and efficient, the object of essential safety.
Accompanying drawing explanation
The pneumatic sampler structural representation that Fig. 1 provides for the utility model embodiment.
Embodiment
Below in conjunction with embodiment, the utility model is elaborated.Wherein identical parts represent with identical Reference numeral.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
The pneumatic sampler structural representation that Fig. 1 provides for the utility model embodiment, the utility model embodiment provides a kind of goaf sampler, comprises air driven pump 1, wind regime 2 and moisture trap 3.On air driven pump 1, be connected with draft tube 4 for sucking goaf gas and for exporting the escape pipe 5 of goaf gas, air driven pump 1 also comprises power interface 11; Wind regime 2 is connected with power interface 11 by air line 6; One end of moisture trap 3 is connected with draft tube 4, and the other end connects sampling line 7.It will be appreciated by persons skilled in the art that moisture trap can also select the other types such as whirlwind separator of the prior art or pressurized air moisture trap, do not do concrete restriction at this.
Air driven pump 1 can adopt the mine pneumatic membrane pump that in prior art, model is BQG-350/0.2, this pneumatic diaphragm pump is mining intrinsic safety type air pump, utilize the pressure differential of air chamber in air driven pump 1 to produce the normal pressure that sucks goaf gas, preferably, in air line 6, be provided with pressure-regulating valve 8.Utilize pressure-regulating valve 8 to control and extract the needed pressure of gas sample, the sampling line 7 of drawing from goaf observation port is connected with moisture trap 3, turns round after 2-3 minute until air driven pump 1, can obtain true gas sample.
The gas sample collecting can be transported in checkout equipment by escape pipe 5, preferably, is provided with blowdown valve 9 in escape pipe 5, and blowdown valve 9, for the protection of the gas outlet of air driven pump 1, prevents the excessive damage that causes air driven pump 1 of pressure by the adjusting of blowdown valve 9.
Further, moisture trap 3 can adopt gravity type moisture trap, and its principle of work is because the proportion of water and gas is different, causes water droplet decline rate to be greater than air-flow ascending velocity, sinks to device bottom under water, and gas rises from outlet output.Rely on the difference of air water gravity by gas and fluid separation applications, can also guarantee by ways such as reduction of speed bufferings the purity of gas sample simultaneously.
On the basis of above-described embodiment, wind regime 2 can adopt in prior art on ground the air compressor of compressor house to provide stable power source for down-hole.
Preferably, it is the high-pressure rubber pipe of 25mm that air line 6 adopts internal diameter, and it is flexible, and bearing capacity is strong, can realize and effectively docking with air above the mine compressor, for air driven pump 1 provides power source.
