Description

Cut main rifle igniter

Technical field

The utility model relates to the main rifle igniter of a kind of cutting.

Background technology

The continuous casting cutting machine is one of nucleus equipment during conticaster is produced, and the scale that it is finished strand by gas-firing oxygen cuts, and combustion gas and oxygen combustion consumption costs are the main energy consumptions in the scale cutting process.

Former design cutting machine is lighted cutting gun and is adopted the mode that electric ignition device is installed to cut down the consumption of energy, and main burning torch can stop burning when not working, and lights main burning torch when cutting.Electric ignition device is chewed by a fire-box, spark lever, igniting and is formed.

The drawback of electric ignition device:

(1), the spark lever of igniter, high-tension cable, igniting chew and must just tighten, and do not tighten and can not light a fire, and high-tension cable and some fire-box must connect and could light a fire, can not light a fire when connecting, otherwise will puncture aviation plug.

(2), igniting a time can not surpass 20s, uses continuously, sparking can not surpass three times, three times continuously after the sparking time intervals be no less than 10 minutes, be unfavorable for the realization of the continuous production cutting function of on-the-spot conticaster.

(3), the maintenance igniter constantly will notice that Keep Clear-High Voltage, brought danger to cutting operation like this, and high-tension cable can damage also in spark lever inside because of ambient temperature is too high.

Directly adopted the Chang Minghuo mode to realize the scale cutting afterwards, before the cutting, main rifle does not have preheat oxygen and natural gas in burning always yet, is in the state of being lighted, during cutting, again by transferring hyperbaric oxygen cutting to.The natural gas preheated oxygen is still consuming in each scale cutting interval procedure, and in big section production process, still there is the bigger problem of energy consumption in most of the time post rifle all in the wait process.

Summary of the invention

At structural deficiency in the prior art, the purpose of this utility model provides a kind of rational scale that can adapt to site environment and cuts main rifle igniter, is beneficial to reach the purpose that reduces natural gas oxygen energy consumption, thereby reduces cutting cost.

For achieving the above object, the technical solution adopted in the utility model provides the main rifle igniter of a kind of cutting, this device includes the valve platform that is fixed in the burning torch on the cutting car body and source of the gas is provided, burning torch is fixed on a side of main cutting gun, wherein: the rifle mouth of described burning torch and main cutting gun form 10-20 degree inclination angle, and pointing to main cutting gun, the rifle mouth is fixed on the cutting car body by barral of a gun.

Effect of the present utility model is after adopting utility model to cut main rifle igniter, only just produces the energy consumption of natural gas and oxygen in cutting process, waits for the gas consumption that trace is only arranged in the cutting process, and every stove steel can reduce cutting combustion gas energy consumption about 65%.

The specific embodiment

Reaching embodiment in conjunction with the accompanying drawings is illustrated the main rifle ignition device structure of cutting of the present utility model.

The main rifle igniter of cutting of the present utility model, this device includes the valve platform that is fixed in the burning torch on the cutting car body 4 and source of the gas is provided, burning torch is fixed on a side of main cutting gun 3, the rifle mouth 1 of described burning torch forms 10-20 degree inclination angle with main cutting gun 3, and pointing to main cutting gun 3, rifle mouth 1 is fixed on the cutting car body 4 by barral of a gun 2.

The rifle mouth 1 of described burning torch includes gun barrel 2-1, and the inner of gun barrel 2-1 is provided with rifle core 2-2, and the periphery of gun barrel 2-1 is provided with rifle cover 2-3, has a plurality of uniform small pores on the rifle core 2-2, and the side of rifle cover 2-3 has plays windproof and hold together the opening of fire action.

Described valve platform includes provides a plurality of branch roads source of the gas and that be communicated with main line, described main line to be provided with person in charge ball valve 3-3 and temper device 3-4, is respectively equipped with branch road ball valve 3-1, manual pressure regulating valve 3-2 and Pressure gauge 3-5 on described each branch road.

The main rifle igniter of cutting of the present utility model is achieved in that

Shown in Fig. 1 and Fig. 3 a, Fig. 3 b, the main rifle igniter of cutting of the present utility model is made up of two parts, and as the cutting igniting mounted point firelock of Fig. 1 and the cutting igniter valve platform of Fig. 3.Among Fig. 1, the rifle mouth 1 that cuts main rifle igniter and gun barrel 2 are by being threaded, and gun barrel 2 is fixed on the cutting car body 4 by pipe clamp 5, and the rifle mouth 1 of burning torch forms 10-20 degree inclinations angle with main cutting gun 3, and points to main cutting gun 3; Main cutting gun 3 is connected with the metal hose 6 of delivery of fuel gas.
