Abstract

The utility mode relates to cutting torch auxiliary lighting equipment of a continuous casting flame cutting machine, comprising an air inlet adapter, a threaded torch head, a torch head and an ignition device, wherein the air inlet adapter is connected with one end of the torch head. The ignition device comprises an ignition mouth, an ignition sheath and an ignition baffle plate. A cone core and a threaded inner tube are arranged in the torch head, the cone core is communicated with the air inlet adapter, and the threaded inner tube is fixedly connected in the torch head. One end of the torch body is connected with the torch head, and the other end is connected with the ignition mouth. The external thread of the ignition mouth is connected with the ignition sheath welded with the ignition baffle plate. The burning torch has simple structure and convenient use. The torch only needs little fuel gas and uses air for supporting combustion, and the burning torch can ignite all the time in the whole production process. Fuel gas consumption is little, and flame is tiny. The burning torch only plays a role of ignition, does not affect the normal use of the original burning torch spare parts, saves energy consumption and increases production efficiency.

Description

A kind of burning torch

Technical field

The utility model relates to a kind of cutting torch aid lighting equipment of continuous casting flame cutting machine, relates in particular to a kind of burning torch.

Background technology

In continuous casting of iron and steel was produced, the steel billet that comes out from crystallizer was successional, need be cut to cut lengths with flame cutting equipment.This just needs the flame cutter in the cutting equipment, the air inlet port that the flame cutting is robbed is connected to cutting oxygen, preheated oxygen, combustion gas, open preheated oxygen and combustion gas during normal the cutting earlier, and light, preheating steel billet 5-10 is after second, and cutting oxygen is opened and is begun cutting, when cutting finished, cutting oxygen magnetic valve cut out earlier.If this moment preheated oxygen, combustion gas also closed, treat that steel billet flows out when cutting once more after the cut lengths, burning torch can not be lighted automatically, has only just can finish down the road by the manual firing and cut.Generally cut the oxygen magnetic valve in the past and close earlier, preheated oxygen, combustion gas are not closed, and that is to say, when burning torch did not cut steel billet, cutting torch still had fire, and flame is bigger, for cutting next time is prepared.Owing to cut oxygen gas one in advance and heading straight for, increased the carbon distribution in the cutting torch, reduced the life-span of burning torch, cutting torch.A large amount of combustion gas and oxygen have also been consumed.

The utility model content

The utility model provides a kind of burning torch in order to overcome the above problems, this rifle only need lead to a small amount of combustion gas, use air-breathing, can light in whole process of production always, gas consumption seldom, flare is faint, only play ignition action, do not influence the normal use of former burning torch spare part, saved energy resource consumption, improve production efficiency, be each big steel factory energy efficiency.

The technical solution of the utility model is: include inlet suction port, threaded rifle head, the body of a gun, igniter, described inlet suction port is connected an end of rifle head, igniter includes ignition tip, igniting cover, igniting baffle plate, be provided with circular cone core and screw thread inner core tube in the rifle head, the circular cone core communicates with inlet suction port, the screw thread inner core tube is fixedly connected in the rifle head, the described body of a gun one end is connected with the rifle head, the other end is connected with ignition tip, and the external screw thread of ignition tip is connected with the igniting cover that is welded with the igniting baffle plate.

The utility model is simple in structure, and is easy to use, and this rifle only need lead to a small amount of combustion gas, use air-breathing, in whole process of production, can light always, gas consumption seldom, flare is faint, only play ignition action, do not influence the normal use of former burning torch spare part, saved energy resource consumption, improved production efficiency, under the present stagnant situation of iron and steel, be each big steel mill energy efficiency.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

1 is inlet suction port among the figure, the 2nd, and circular cone core, the 3rd, rifle head, the 4th, screw thread inner core tube, the 5th, the body of a gun, the 6th, two nipples, the 7th, ignition tip, the 8th, igniting cover, the 9th, igniting baffle plate, the 10th, hold-down screw.

The specific embodiment

A kind of burning torch, include inlet suction port 1, threaded rifle head 3, the body of a gun 5, igniter, described inlet suction port 1 is connected an end of rifle head 3, igniter includes ignition tip 7, igniting cover 8, igniting baffle plate 9, be provided with circular cone core 2 and screw thread inner core tube 4 in the rifle head 3, circular cone core 2 communicates with inlet suction port 1, screw thread inner core tube 4 is fixedly connected in the rifle head 3, the described body of a gun 5 one ends are connected with rifle head 3, the other end is connected with ignition tip 7, and the external screw thread of ignition tip 7 is connected with the igniting cover 8 that is welded with igniting baffle plate 9.In circular cone core 2 precession rifle heads 3, again screw thread inner core tube 4 is screwed in rifle head 3, regulate the spacing between screw thread inner core tube 4 and the circular cone core 2, be tightened screw 10 with retaining thread inner core tube 4, combustion gas enters circular cone core 2 in the rifle head 3 by inlet suction port 1, the passage diameter of circular cone core 2 is 0.8mm, one end of the body of a gun 3 is threaded with rifle head 3, the other end is connected with ignition tip 7, the external screw thread of ignition tip 7 is connected with the igniting cover 8 that is welded with igniting baffle plate 9, combustion gas enters rifle head 3 backs by the body of a gun 5, and at ignition tip 7 places and air mixing ignition, flare is lighted a fire below the baffle plate 9 introducing flame cutting machine cutting torch.

Claims

1. burning torch, include inlet suction port, threaded rifle head, the body of a gun, igniter, described inlet suction port is connected an end of rifle head, igniter includes ignition tip, igniting cover, igniting baffle plate, it is characterized in that: be provided with circular cone core and screw thread inner core tube in the rifle head, the circular cone core communicates with inlet suction port, the screw thread inner core tube is fixedly connected in the rifle head, the described body of a gun one end is connected with the rifle head, the other end is connected with ignition tip, and the external screw thread of ignition tip is connected with the igniting cover that is welded with the igniting baffle plate.
