Description
Technical field
The utility model relates to gas discharge in mine field, is specially the anti-device that transfinites of a kind of coal mine drilling gas.
Background technology
Colliery has polarization, drilling depth length, single hole gas density and pumping volume high when carrying out drilling construction, especially for Gas Outburst mine, cannot effective keyhole gas in the process of firedamp taking-out discharging drilling construction, cause the security incident of gas exceeding limit.So draw out methane in system at mine, delivery box is one of indispensable device, and its effect is that the gas extracted out in boring is separated with water, is bled off by water, only allows gas enter pipeline.Current gas suction by drilling delivery box used is welded with iron sheet, there is following defect in actual use, such as:
1, owing to adopting multiple welding, body is firm not, there will be casing " breathing " situation, cause casing to burst apart under suction function;
2, easily pile up cinder in case, not easily rinse;
3, casing is non-dismountable, heavy, removal of home difficulty;
Have a strong impact on negative pressure when 4, discharging water, in the process that repeatedly discharges water, negative pressure reduces to cause to transfinite;
5, the water capacity is returned easily by casing inspiration main line.
Summary of the invention
There is the problem of above-mentioned many defects in the utility model, provides a kind of coal mine drilling gas the anti-device that transfinites in order to solve existing drill mash gas water tank used.
The utility model adopts following technical scheme to realize: the anti-device that transfinites of coal mine drilling gas, comprise U-steel frame, be erected at upper delivery box on U-steel frame and lower delivery box, upper delivery box top is provided with some air inlet ports and gas outlet, each air inlet port and gas outlet are installed straight-through, straight-through outlet has quick butterfly valve by Flange joint; Be provided with outlet pipe bottom upper delivery box two ends, top, lower delivery box two ends is communicated with corresponding outlet pipe respectively by armored pipes, is provided with gutter bottom lower delivery box two ends, and outlet pipe and gutter are equipped with quick butterfly valve.
Described upper delivery box and lower delivery box are all the seal cases be welded into by the steel plate plug at cylinder iron pipe and two ends, and owing to being cylinder, body affects little by negative pressure, not fragile.
Described gas outlet leads directly to into large tripe leads directly to, after connecting main line negative pressure, due to caliber change, negative pressure has certain buffering effect, not easily water is sucked main line.
Described air inlet port quantity is six, and gas outlet quantity is two.
Be provided with upper and lower two-layer sieve plate in described upper delivery box, the mesh of upper and lower two-layer sieve plate is crisscross arranged, and ensures sieving effect.
Adopt structure design of the present utility model, compared with prior art, have the following advantages:
1, the jettison gear of processing and manufacturing uses finished product Φ 350 iron pipe, and only become Φ 108 plug at two welding Φ 350, owing to being cylinder, body affects little by negative pressure, not fragile;
2, respectively there is a valve left and right, and during accumulation coal slime, available water is rinsed;
3, dismounting is simple, and removal of home is convenient;
4, adopt upper and lower two-layer design, centre has Valve controlling to isolate, and the valve-off when discharging water can not affect boring negative pressure;
5, process large tripe to lead directly to, after connecting main line negative pressure, due to caliber change, negative pressure has certain buffering effect, not easily water is sucked main line;
In a word, the utility model reasonable in design, cost of manufacture are low, dismounting simply, not fragile, coal mine drilling gas drainage system can be widely used in.
