Description
Technical field
The present invention relates to a kind of steel-making continuous casting cutter sweep, particularly relate to a kind of continuous casting cutting gun igniter.
Background technology
In steel-making continuous casting cutting, usual employing be combustion gas cutting, due to the particularity that steel-making continuous casting cutting is produced, the cutting of steel is intermittent and noncontinuity, and cutting gun can not be followed intermittent igniting and be stopped working in batch process, one be igniting cutting working time and the intermittent time all very short, cutting gun has little time followed by intermittent igniting and stop working, even if two is that cutting gun has such sensitivity, the waste of its combustion gas is also very surprising, and very large on the impact of igniter, lose more than gain; Therefore the mode that existing continuous casting cutting gun typically uses Chang Minghuo carries out work, once continuous casting cutting gun igniter would not be extinguished by ignition operation, the combustion gas waste caused like this is very serious.
Utility model content
The object of the invention is the deficiency existed for prior art, a kind of continuous casting cutting gun igniter is provided.This igniter structure is simple, easy to use, low cost of manufacture, and ignition results is good, and air consumption is minimum, and ever-burning flame burning cost is low.
The technical solution of the utility model comprises 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, described mixing chamber corresponds to described injecting tube and is provided with one or be laid with some for air regulator.
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 (exit end) is provided with the 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, described in lead fiery device and be connected in mixing chamber or afterflame extending chamber.
It is described that to lead fiery device be a fire conduction plate comprising L shape.
Described injecting tube comprises two sections, and described two sections of injecting tubes are with mutually corresponding to being one in front and one in back positioned at described mixing chamber for air regulator; The cutting torch that described firing gun body corresponds to continuous casting cutting gun is located on continuous casting cutting gun.
Igniter of the present invention not only structure is simple, be easy to manufacture, install and use also very convenient simultaneously, particularly because the gas consumption under its normal ignition fired state is minimum, and flare is not easily blown out, can remain ever-burning flame, as long as continuous casting cutting gun just can extinguish in the intermittent time that slightly works, when continuous casting cutting gun works, igniting is not only timely but also reliable.
Accompanying drawing explanation
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.
Detailed description of the invention
Now by embodiment, also the present invention will be further described by reference to the accompanying drawings.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 perisporium, be that the injecting tube 1 of a capillary is connected by the fuel gas inlet end of the inner chamber movable and mixing chamber 2 that are inserted in mixing chamber 2 as the thread bush 4 of its adjusting device, gas outlet one end of injecting tube 1 corresponds to the confession air regulator 3 of mixing chamber 2, is extended regulate with the correspondence position relation for air regulator 3 of mixing chamber 2 by the injecting tube 1 of thread bush 4 pairs of capillary types; 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 is connected to carry out movable as the screw connection of its adjusting device mutually with mixing chamber 2, is regulated effective active length (the inner chamber flame bundle) length of afterflame extending chamber 6 by this screw connection; Be laid with multiple combustion-supporting hole 7 in one end by mixing chamber 2 of afterflame extending chamber 6 around afterflame extending chamber 6 perisporium, combustion-supporting hole 7 is from outer past interior along gas-flow to inclination; Be connected with one at the sidepiece of one end in the outer part of afterflame extending chamber 6 and be similar to L shape deflector 8.
The present invention penetrates suction effect by the injecting tube of capillary type, utilize the flow velocity of combustion gas in mixing chamber by the abundant mixing for air regulator, air intake mixing chamber being carried out combustion gas and air on mixing chamber, due to the special structure of injecting tube and mixing chamber, add the progradation of afterflame extending chamber, its air sucked carries out adjustment eddy flow with combustion gas and mixes in mixing chamber, the fuel combustion duty of igniter is in fact be in the inflammable substance based in combustion air, with the fired state that combustion gas is auxiliary, to use up all imflammable gas entered in the air of mixing chamber, acted on by porous plate distribution, air and combustion gas are evenly made thinner distribution, further can help the burning to the inflammable substance in air simultaneously, and many flame bundle combustion distribution can also be reached by porous plate, be finally guided to the cutting torch of corresponding continuous casting cutting gun by fire conduction plate, it is lighted a fire, in the process of igniter work, combustion-supporting hole also by afterflame extending chamber supplements air, and to reach Thorough combustion, the setting of combustion-supporting hole can reduce the resistance of combustion gas, accelerating the effluxvelocity of mist, is equally also in order to the inflammable substance in Thorough combustion air, in addition, the effect of afterflame extending chamber and porous plate also can avoid external wind to extinguish igniter kindling material.
By injecting tube and the adjustment for the mutually corresponding position relationship of air regulator, and then the quantity delivered (combustion gas and air ratio) of adjustment air, with the igniting flare of regulable control firing gun body 9, make it adapt to different onsite application environment.
Another embodiment of the present invention as shown in Figure 3, in this example, injecting tube 1 is formed by being in tandem two sections of mixing chamber 2 inner chamber, mutually corresponding and corresponding for air regulator 3 respectively with mixing chamber 2 of the end in opposite directions of two sections of injecting tubes 1, two sections of injecting tubes 1 spacing each other and can regulating at the same time or separately as required respectively and for the mutual correspondence position between air regulator 3.Different fired states can be obtained by arranging two sections of injecting tubes, also can adapt to different environment for use and different continuous casting cutting guns igniting use.
As shown in Figure 4, in this example, firing gun body 9 and continuous casting cutting gun 10 are arranged at one to yet another embodiment of the invention, and the fire conduction plate 8 of firing gun body 9 corresponds to cutting torch 11 direction 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.
