Abstract

The utility model discloses a curtain type sintering ignition furnace. The ignition furnace comprises a furnace body, support frames in bilateral symmetry are fixedly mounted at the bottom of the furnace body, symmetrical fire-proof inner linings are arranged on the inside wall of the furnace body and are positioned on the symmetrical support frames, a plurality of guide pipes are orderly mounted between the two fire-proof inner linings, nozzles are mounted at the upper ends of the guide pipes and the lower ends of the nozzles are communicated with a first air pipe and a second air pipe, a channel is arranged at the lower ends of the guide pipes, a fixed bracket is fixed outside the furnace body, and a gas pipe line is communicated with the bottom of the furnace body. The curtain type sintering ignition furnace has the advantages of small volume, low hearth, novel design of the nozzles, simple structure, adjustable flame length, high ignition efficiency, short time, long service life, good charge level ignition quality, and uniform ignition along width direction of a trolley, avoids over-melting, and improves the air permeability of charge level.

Description

Curtain formula sintering ignition furnace

Technical field

The utility model relates to a kind of curtain formula sintering ignition furnace, belongs to the sintering technology field.

Background technology

Igniting is an important link in the sintering process flow process, in the sintering process in modern times, utilizes ignition furnace to mix surface thermal-flame to be provided; Solid fuel ignition inside making, and make surperficial compound sintering under the condition of heat burning, the quality of igniting directly has influence on the progress of sintering process and the intensity of sintering; Firing temperature is low excessively, and the energy of surperficial sinter mixture savings is not enough to provide the burning condition of abundance to subsurface material very little; Can't make the surface of compound reach the intensity of sintering, otherwise the temperature of igniting is too high or burning time is long; Can cause the combustion mix surface to cross to dissolve again and influence the air communication mistake; Reduce bed of material air penetrability, reduce vertical sintering speed, thereby cause productivity ratio to reduce.

The utility model content

The purpose of the utility model is to provide a kind of curtain formula sintering ignition furnace.

The utility model adopts following technical scheme:

Curtain formula sintering ignition furnace comprises body of heater, it is characterized in that: described bottom of furnace body is installed with symmetrical bracing frame; The madial wall of described body of heater is provided with the refractory lining of symmetry; Described refractory lining is positioned on the bracing frame of symmetry, and several orderly conduits are installed between described two refractory linings, and described conduit upper end is equipped with burner; Described burner lower end is communicated with first airduct and second airduct; Described conduit lower end also is provided with passage, and described body of heater is fixed with fixed mount outward, and described bottom of furnace body also is communicated with gas piping.

The advantage of the utility model:

(1) adopt the instantaneous direct-fire technology of the advanced high temperature in home and abroad, the type of furnace is little, burner hearth is low;

(2) burner of points of engagement stove is novel in design, and simple in structure, the length of flame can be regulated and control, and helps the formation of rigidity flame, and burner is strong to the variation adaptability of thermic load, and ignition effectiveness is high, and the time is short, long service life;

(3) the charge level ignition quality is good, along the igniting of chassis width evenly, does not produce and dissolves phenomenon, can improve the gas permeability of charge level.
