Description
Technical field
The present invention relates to a kind of steel-making continuous casting cutter sweep, relate in particular to a kind of continuous casting cutting gun igniter.
Background technology
In the steel-making continuous casting cutting, what usually adopt is the combustion gas cutting, because the particularity that the steel-making continuous casting cutting is produced, the cutting of steel is intermittence and noncontinuity, and cutting gun can not be followed intermittent igniting and flame-out in batch process, the one, working time and the intermittent time of igniting cutting are all very short, cutting gun has little time following intermittent igniting and flame-out, the 2nd, even cutting gun has such sensitivity, the waste of its combustion gas also is very surprising, and very large on the impact of igniter, lose more than gain; Therefore the existing continuous casting cutting gun mode that typically uses Chang Minghuo is carried out work, in case the continuous casting cutting gun igniter just can not extinguished by ignition operation, the combustion gas waste that causes like this is very serious.
Summary of the invention
The objective of the invention is the deficiency for the prior art existence, a kind of continuous casting cutting gun igniter is provided.This igniter structure is simple, and is easy to use, low cost of manufacture, and it is effective to light a fire, and air consumption is minimum, and ever-burning flame burning cost is low.
Technical scheme of the present invention comprises the firing gun body body, and described firing gun body body comprises injecting tube, and described injecting tube one end is arranged with a mixing chamber, is provided with one or be laid with some for air regulators corresponding to described injecting tube on the described mixing chamber.
Described injecting tube is fixed or is connected with described mixing chamber by an adjuster, and described injecting tube is adjusted by this adjuster with the correspondence position for air regulator.
Described injecting tube is a capillary.
Described mixing chamber one end (exporting an end) is provided with a distribution grid that comprises porous plate.
Described mixing chamber is fixed or is connected with an afterflame extending chamber by an adjusting device.
Described afterflame extending chamber is provided with one or be laid with some combustion-supporting holes.
Described combustion-supporting hole tilts along described afterflame extending chamber Way out.
Described mixing chamber one end is connected with one and leads fiery device, describedly leads fiery device and is connected in mixing chamber or the afterflame extending chamber.
It is described that to lead fiery device be one to comprise L shaped fire conduction plate.
Described injecting tube comprises two sections, described two sections injecting tubes with one in front and one in back be positioned at described mixing chamber for air regulator mutual corresponding being; Described firing gun body is located on the continuous casting cutting gun corresponding to the cutting torch of continuous casting cutting gun.
Igniter of the present invention is not only simple in structure, be easy to make, install and use simultaneously also very convenient, particularly because the gas consumption under its normal ignition fired state is minimum, and flare is difficult for being blown out, can remain ever-burning flame, as long as continuous casting cutting gun slightly having the work intermittent time just can extinguish, when continuous casting cutting gun is worked, light a fire not only in time but also reliable.
Description of drawings
Fig. 1 is igniter one example structure schematic diagram of the present invention; Fig. 2 is Fig. 1 top view; Fig. 3 is another embodiment of the present invention structural representation; Fig. 4 is yet another embodiment of the invention structural representation.
The specific embodiment
Now also the present invention will be further described by reference to the accompanying drawings by embodiment.As shown in Figure 1, 2, firing gun body 9 comprises a mixing chamber 2, the corresponding position of mixing chamber 2 is laid with 2 to 4 for air regulator 3 around mixing chamber 2 perisporiums, be that an injecting tube 1 capillaceous is inserted in mixing chamber 2 by the thread bush 4 as its adjusting device inner chamber movable is connected with the fuel gas inlet end of mixing chamber 2, gas outlet one end of injecting tube 1 corresponding to mixing chamber 2 for air regulator 3, the injecting tube 1 by 4 pairs of capillary types of thread bush extends with the correspondence position relation for air regulator 3 of mixing chamber 2 to be regulated; Gas outlet one end of mixing chamber 2 is connected with the orifice plate 5 of porous type, gas outlet one end of mixing chamber 2 is provided with an afterflame extending chamber 6, afterflame extending chamber 6 mutually carries out movable with the screw connection as its adjusting device with mixing chamber 2 and is connected, and regulates effective active length (inner chamber flame bundle) length of afterflame extending chamber 6 by this screw connection; The end by mixing chamber 2 in afterflame extending chamber 6 is laid with a plurality of combustion-supporting holes 7 around afterflame extending chamber 6 perisporiums, and combustion-supporting hole 7 is from outer past interior along gas-flow to inclination; Be connected with one at the in the outer part sidepiece of an end of afterflame extending chamber 6 and be similar to L shaped deflector 8.
The present invention is by the suction effect of penetrating of the injecting tube of capillary type, utilize the flow velocity of combustion gas in mixing chamber the air intake mixing chamber to be carried out the abundant mixing of combustion gas and air by the air regulator that supplies on the mixing chamber, because the special structure of injecting tube and mixing chamber, add the progradation of afterflame extending chamber, the air of its suction is adjusted eddy flow with combustion gas and is mixed in mixing chamber, the fuel combustion duty of igniter is in fact to be in inflammable substance in the combustion air as main, take combustion gas as auxiliary fired state, to use up airborne all imflammable gas that enter mixing chamber; Simultaneously by porous plate distribution effect, air and the combustion gas distribution of evenly making thinner can further help the burning to airborne inflammable substance; And can also reach many flame bundle combustion distribution by porous plate, and be guided at last the cutting torch place of corresponding continuous casting cutting gun by fire conduction plate, it is lighted a fire; In the process of igniter work, also can replenish air by the combustion-supporting hole of afterflame extending chamber, to reach abundant burning, the setting of combustion-supporting hole can reduce the resistance of combustion gas, accelerating the effluxvelocity of mist, equally also is for the inflammable substance in the abundant combustion air; In addition, the effect of afterflame extending chamber and porous plate also can avoid external wind to extinguish the igniter kindling material.
By the adjusting of the injecting tube position relationship mutual corresponding with supplying air regulator, and then the quantity delivered (combustion gas and air ratio) of regulating air, to regulate the igniting flare of control firing gun body 9, make the different on-the-spot environment for use of its adaptation.
Another embodiment of the present invention as shown in Figure 3, in this example, injecting tube 1 consists of by being in tandem two sections of mixing chamber 2 inner chambers, the in opposite directions end of two sections injecting tubes 1 is corresponding, and corresponding for air regulator 3 with mixing chamber 2 respectively mutually, two sections injecting tubes 1 each other spacing and can regulate at the same time or separately as required respectively and for the mutual correspondence position between the air regulator 3.Can obtain different fired states by two sections injecting tubes are set, also can adapt to different environments for use and use with different continuous casting cutting gun igniting.
Yet another embodiment of the invention as shown in Figure 4, in this example, firing gun body 9 is arranged at one with continuous casting cutting gun 10, the fire conduction plate 8 of firing gun body 9 is corresponding to cutting torch 11 directions of continuous casting cutting gun 10.
Other modified products based on the technical scheme of this continuous casting cutting gun igniter all belong to protection scope of the present invention; Above-described embodiment is not the exhaustive of the specific embodiment of the present invention.
