Description
Technical field
The present invention relates to the bottle coal separator.More specifically say so and a kind ofly be applied in projecting coal bed safety and creep into bottle coal separation equipment in the blowout prevention system.
Background technology
Projecting coal bed, especially the severe outburst coal drilling construction is still global problem so far.Be that wet type is crept into or dry type is crept into and strong spray orifice phenomenon all can be occurred, even the outstanding accident of boring takes place.The two is compared, adopt waterpower (water under high pressure) to creep into for the wet type of cooling chip removal medium, the spray orifice situation is more violent in the drilling process, moment or can spray a large amount of coals and gas in short-term, and be in runaway condition again, can not only cause gas exceeding limit, bottle coal impacts the personnel that hurt sb.'s feelings, suffocate, and causes the hidden danger of gas explosion accident simultaneously in addition.And adopt wind-force (pressure wind) to creep into for the dry type of cooling chip removal medium, though spray orifice intensity weakens relatively, drilling construction is easier to relatively, also still has above-mentioned threat; Another hidden danger that the wind power slag-discharging dry type is crept into is the subsidiary a large amount of coal dusts that produce, it is healthy not only directly to injure the operating personnel, and its serious again sight line of covering the personnel that creep into, can't carry out correct operation, more can't identification creep into the interior dynamic phenomenon of mesopore, frequently cause the accident of creeping into, the hidden danger that causes coal-dust explosion is also arranged.
Major diameter rapid hole sealing device is set realizes quick sealing of hole, and the filtering type cylinder is set in the aperture, thereby guarantee in normal advance and retreat of drilling rod and rotation, coal and gas forward spray in can the block hole, can be two-way with the cinder that sprays in the hole and the smooth drainage of gas and rough segmentation again, make outstanding gas major part introduce follow-up extraction system, still by gas channel, meanwhile, still contain a certain amount of gas through in the cinder of crude separation.At present, also do not have a kind of equipment effectively to separate this outstanding cinder that contains gas, the direct emptying of gas not only causes energy waste, also brings environment pollution simultaneously.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, provides a kind of and is applied in projecting coal bed safety and creeps into bottle coal separation equipment in the blowout prevention system, makes gas be collected utilization fully, and avoids environment pollution.Creep into for projecting coal bed safety and to create more advantageous conditions, fundamentally eliminate the outstanding potential safety hazard of bringing of strong spray orifice of boring or boring.
The technical scheme that technical solution problem of the present invention is adopted is:
Design feature of the present invention is the spiral-flow type bottle coal to be set catch the dirt storehouse smart the branch, the described dirt storehouse of catching is a cylinder, material inlet is tangential setting on the barrel of cylinder, fog-spray nozzle is set in the cylinder, storehouse, the top cap that snaps onto on the cylinder links to each other with extraction pipeline by storehouse cap exhaust opening, be provided with in the cap of storehouse cinder is entered the sieve plate that storehouse cap exhaust opening formation stops, taper cinder bucket is accepted in the bottom of cylinder, and the slag-drip opening that is provided with residual cake valve is positioned on the end mouth of cinder bucket.
Design feature of the present invention also is:
In described cylinder, one section arc eddy flow plate is set, described eddy flow plate and cylinder sidewall form arc eddy flow chuck, the eddy flow chuck binds with cone screen plate, the eddy flow inlet of chuck, eddy flow outlet and chuck bottom thereof are uncovered, and the described material inlet that is tangential setting directly leads to the eddy flow inlet of chuck.
Described fog-spray nozzle is a Multi-direction spray head, is positioned at the top of eddy flow chuck, is annular along the cylinder sidewall and distributes.
Described storehouse cap is the spherical crown shape.
Described bottle coal separation equipment is arranged on the portable pedestal.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is provided with the spiral-flow type bottle coal and catches the dirt storehouse smart the branch, integrate to separate and catch dirt, by the incident kinetic energy that comes self-drilling bottle coal mixed flow thing, tangentially enter catch the dirt storehouse after, form eddy flow, realize the sorting of gas and cinder fast.
2, the present invention is by being provided with the eddy flow plate, and forms arc eddy flow chuck with the cylinder sidewall, can effectively improve its separating effect and the efficiency of separation.
3, spherical crown shape of the present invention storehouse cap can reduce wind resistance.
4, integral body of the present invention is arranged on the portable pedestal, moves conveniently.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a sieve-plate structure schematic diagram of the present invention.
Fig. 3 is I of the present invention-I sectional structure schematic diagram.
Number in the figure: 1 catches dirt storehouse, 2 material inlets, 3 fog-spray nozzles, 4 storehouse caps, 5 storehouse cap exhaust openings, 6 extraction pipelines, 7 sieve plates, 8 cinder buckets, 9 residual cake valves, 10 eddy flow plates, 11 eddy flow chucks, 12 cone screen plates, 13 cinder transporters, 14 portable frames.
Below pass through the specific embodiment, and in conjunction with the accompanying drawings the present invention is further described.
The specific embodiment
Referring to Fig. 1, Fig. 3, the spiral-flow type bottle coal is set catches dirt storehouse 1 smart the branch, catch dirt storehouse 1 and be cylinder, material inlet 2 is tangential setting on the barrel of cylinder, fog-spray nozzle 3 is set in the cylinder, storehouse, the top cap 4 that snaps onto on the cylinder links to each other with extraction pipeline 6 by storehouse cap exhaust opening 5, be provided with in the storehouse cap 4 cinder is entered the sieve plate 7 that cap exhaust opening 5 formation in storehouse stop, taper cinder bucket 8 is accepted in the bottom of cylinder, the slag-drip opening that is provided with residual cake valve 9 is positioned on the end mouth of cinder bucket 8, below slag-drip opening, cinder transporter 13 is set.
The form of structure of sieve plate 7 as shown in Figure 2.
