The invention discloses an ignition device of a cutting torch, which has the advantages of simple and reasonable structure, reliable ignition, energy saving and safety. The ignition device comprises an ignition torch which corresponds to a cutting head; an ignition gas passageway of the ignition torch and a cutting gas passageway of the ignition torch are respectively provided with electromagnets which are electrically connected with an intelligent controller; and an oxygen supplying hole which is communicated with atmosphere is arranged on an ignition burner of the ignition torch.

Description

The igniter of burning torch
Technical field
The present invention relates to a kind of steel-making continuous casting cutter sweep, relate in particular to a kind of igniter that is used for the burning torch of steel-making continuous casting cutting.
Background technology
In steel-making continuous casting was produced, the cutting speed and the reliability of cutting tool were the very important factors that the restriction steel-making continuous casting is produced, and therefore require cutter sweep to have higher continuous casting cutting speed, to satisfy the demand of the casting speed that improves day by day.The consumption of cutting combustion gas then directly has influence on the production and operation benefit, and these all with use cut the tool quality, the integral body of cutting tool constitutes and method for using, cutting technique, ignition method and the device etc. that cut tool have direct relation.For the igniting of cutting tool, the existing tool that cuts generally uses the manual firing, and its defective of this mode is very tangible; And be the needs that adapt to continuous casting manufacturing technique; In order to avoid because of light a fire untimely influence automatic ignition device that the production of throwing continuous casting uses then without exception set up a burning torch; But cooperatively interacting of its burning torch of existing burning torch point and burning torch is not ideal enough; Occur easily igniting too early, cross evening or point not etc. problem, even tempering phenomenon occurs or set off an explosion.
Summary of the invention
The objective of the invention is deficiency, a kind of igniter of burning torch is provided to the prior art existence.It is simple, reasonable that this igniter constitutes, and igniting is timely, reliable, energy-conservation, safety.
Technical scheme of the present invention comprises corresponding to the set burning torch of the cutting torch of burning torch; Said burning torch is the electronic ignition rifle that is provided with the electronic striking device; Said burning torch and burning torch are connected with Cutting Gas passage and igniter gas passage respectively; Be respectively equipped with control valve on said Cutting Gas passage and the igniter gas passage, the controlled intelligent controller that is connected in of said control valve is implemented interlock control by intelligent controller to cutting control valve and Burn Ray Control Valve.
The ignition burner of said electronic ignition rifle is provided with the oxygenating hole of one or several UNICOMs in its inner chamber and atmosphere.
On the ignition burner of said electronic ignition rifle set oxygenating hole along the center line of ignition burner outward extreme direction tilt.
The control valve of being located on the Cutting Gas passage of said burning torch is a 3-position-3-way solenoid valve, and the delivery outlet first quarter stream device of 3-position-3-way solenoid valve is connected to its another delivery outlet.
Said cutting control valve and Burn Ray Control Valve are located at respectively in the combustion gas and/or gaseous mixture air supply channel of burning torch and burning torch, and said ignition channel is a throttle type passage.
The igniting opening time of said cutting control valve lags behind the opening time 0.1-2S of Burn Ray Control Valve.
Ignition device of the invention and point guns torch ignition control with the ideal, in time, automatically and reliably achieve torch ignition, especially in the torch gas channel set on two three-way solenoid valve, you can ensure that the cut gun not lit for the first time into the cutting nozzle gas pressure or flow rate of a lower value, to avoid too much pressure on the torch is not lit and blew point guns fire ignition timing Slim or prolong the situation, to the use of small ignition gas consumption to obtain a more reliable ignition effect; simple structure, easy to use.
Description of drawings
Fig. 1 is the igniter one example structure sketch map of burning torch of the present invention.Fig. 2 is another example structure sketch map of igniter of burning torch of the present invention.
The specific embodiment
Existing through embodiment and combine accompanying drawing that the present invention is described further.As shown in Figure 1, the ignition burner of electronic ignition rifle 5 is corresponding each other with the cutting torch of burning torch 1, and burning torch 1 Cutting Gas passage 2 is connected on the gas pipeline through cutting magnetic valve 3, and the ignition channel 8 of electronic ignition rifle 5 is connected on the gas pipeline through igniter solenoid valve 4; Be laid with the oxygenating hole 6 of several UNICOMs in the inner chamber and the atmosphere of ignition burner on the ignition burner of the inner chamber of electronic ignition rifle 5 or electronic ignition rifle 5, oxygenating hole 6 extreme direction outside the past ignition burner of center line one side of lateral ignition burner tilts.
Igniter solenoid valve 4 is connected in PLC Programmable Logic Controller 7 through holding wire respectively with cutting magnetic valve 3, by the action that cooperatively interacts of PLC Programmable Logic Controller 7 control igniter solenoid valves 4 and cutting magnetic valve 3.
During burning torch 1 igniting, open sub-burning torch 5 igniting of igniter solenoid valves 4 power supplies earlier by 7 controls of PLC Programmable Logic Controller and use combustion gas, opening cutting magnetic valve 3 after 1 second is the incisory combustion gas of burning torch 1 supply, can light burning torch in the electronic ignition rifle 5 lighting; Supply with needed other cutting usefulness gas (preheat oxygen and hyperbaric oxygen) of burning torch through the control corresponding valve respectively afterwards, realize the cutting igniting of burning torch.
Set oxygenating hole 6 can utilize igniting combustion gas or the swabbing action of gaseous mixture when flowing in the rifle for the igniting of electronic ignition rifle oxygen to be provided on the ignition burner of electronic ignition rifle 5.Oxygenating hole 6 is skewed makes oxygen supply more smooth.
Another embodiment of the present invention is as shown in Figure 2; Present embodiment is on the basis of the foregoing description; To cut magnetic valve and change 3-position-3-way solenoid valve 3a into; The input port of 3-position-3-way solenoid valve 3a is connected with the gas supply pipeline of burning torch 1, and one of them directly is connected two delivery outlets of cutting magnetic valve 3a with Cutting Gas (combustion gas or the gaseous mixture) passage 2 of burning torch 1, and another first quarter stream device (restricting orifice) 9 is connected with Cutting Gas (combustion gas or the gaseous mixture) passage 2 of burning torch 1.
During burning torch 1 cutting igniting; After electronic ignition rifle 5 supplies combustion gas; By PLC Programmable Logic Controller 7 be that burning torch 1 is supplied with a less combustion gas or gaseous mixture through throttling arrangements 9 earlier, treats that burning torch lights afterwards 3-position-3-way solenoid valve 3a and switch to immediately by another delivery outlet and directly cut fuel gas supply.And then realize the reliable ignition of burning torch with still less consumption gas.
