Abstract

The utility model provides a technical proposal for a top igniter of a blast furnace. The utility model comprises a fire specie gun, a combustion supporting gas soft tube, a combustion supporting gas valve, a fuel gas soft tube, a fuel gas valve, a pulse igniting mechanism and a spark ignition head which is connected with a conducting wire. The utility model is characterized in that the fire specie gun is fixed on a small car; the small car is arranged on guide rails, and the small cars can move along the guide rails; the small car is connected with a steel rope; the steel rope is connected with a traction mechanism; the fire specie gun is fixed between the two guide rails; the specie gun is a double tube structure; an inner fuel gas pipe is connected with the fuel gas soft tube, and the outer combustion supporting gas pipe is connected with the combustion supporting gas soft tube.

Description

State of Blast Furnace summit firearm

But the utility model relates to a kind of lighter for ignition of ignited flammable gas, especially a kind of State of Blast Furnace summit firearm.

When iron-smelting blast furnace when minor casualty occurring or needing repairing, blast furnace need be in the state that temporarily stops operation, be to stop air feed but still be in pyritous damping down state in the stove, owing to have high temperature in the stove, so still have coal gas to exist at furnace roof, this just need light coal gas to ensure safety, putting coal gas in the prior art is to adopt manually to light on the oilcloth input furnace roof charge level, the coal gas that ignites and from furnace charge, overflow, but owing to be in the damping down state, the coal gas amount of overflowing in furnace charge is less, and particularly coal gas is difficult for being lighted when throat temperature is low, automatically extinguish and to light once more after also very easily lighting, regnition or flame-out after fail timely discovery and all be easy to generate sudden and violent ring, jeopardize personnel safety, so need the artificial supervision condition of a fire to light a fire at any time, this has not only increased labour intensity, and personal injury accident also takes place easily.

The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of State of Blast Furnace summit firearm technical scheme is provided, and this scheme can provide long distance ignition, and remains on the kindling material that continous-stable is provided in the furnace roof, has guaranteed safety.

This programme is realized by following technical measures.The burner valve that mainly includes kindling material rifle, combustion-supporting gas flexible pipe and the combustion-supporting valve, the gas hose that are connected and be connected, and the spark ignition head that is connected with lead of pulse firing device, the characteristics of this programme are that described kindling material rifle is to be fixed on the dolly, dolly then is contained on the guide rail, and can move along guide rail, dolly connects steel cable again simultaneously, and steel cable is connected with haulage gear again.The concrete characteristics of this programme also have, and described kindling material rifle is between two guide wheels that are fixed on the guide rail.Described kindling material rifle is a two-layer pipe, and the internal layer gas line is connected with gas hose, and outer combustion-supporting tracheae and combustion-supporting gas are hose connection.

According to as can be known to the narration of such scheme, because the kindling material rifle in this scheme is to be fixed on the dolly, dolly then is contained on the guide rail, and can move along guide rail, dolly connects steel cable again simultaneously, steel cable is connected with haulage gear again, and the kindling material rifle is again that guide wheel has guide effect again between two guide wheels that are fixed on the guide rail.This structure heads on the parts at place, hole as long as guide rail is fixed on State of Blast Furnace by certain angle, the kindling material rifle just can be by haulage gear precise control ground in hand-hole be inserted into the blast furnace furnace roof or outside the proposition blast furnace, realize that the kindling material rifle can be inserted into body of heater inside again behind long distance ignition in blast furnace.Described kindling material rifle is again a two-layer pipe, and the internal layer gas line is connected with gas hose, and outer combustion-supporting tracheae and combustion-supporting gas are hose connection, and this can guarantee that the kindling material rifle can provide stable kindling material.This shows that the utility model compared with prior art no longer needs manually to monitor the condition of a fire, has alleviated labour intensity and has also guaranteed safety, so have substantive distinguishing features and progress, its implementation result also is conspicuous.

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.

Description of drawings:

Fig. 1 is the part sectional structure synoptic diagram of the utility model embodiment.

By accompanying drawing as can be seen, the State of Blast Furnace summit firearm of this programme, the burner valve 11 that mainly includes kindling material rifle 1, combustion-supporting gas flexible pipe 9 and the combustion-supporting valve 10 that is connected, gas hose 13 and be connected, and the spark ignition that is connected with lead of pulse firing device 12 14, the characteristics of this programme are that described kindling material rifle 1 is to be fixed on the

dolly

6, and 6 in dolly is contained on the guide rail 2, and can move along guide rail 2, dolly 6 connects steel cable 8 again simultaneously, and steel cable 8 is connected with haulage gear 7 again.Described kindling material rifle 1 is between two guide wheels 5 that are fixed on the guide rail 2.Described kindling material rifle 1 is a two-layer pipe, and internal layer gas line 3 is connected with gas hose 13, and outer combustion-supporting tracheae 4 is connected with combustion-supporting gas flexible pipe 9.
