Background technology
The air-supply arrangement of the main body system installation of smelting vanadium-titanium magnetite by blast furnace, to be carried for smelting vanadium-titanium magnetite by blast furnace For thermal energy, power source.Tuyere small sleeve is copper part in air-supply arrangement, and price is high, small if there is the bent damage of tuyere small sleeve, air port Set sinks, tuyere small sleeve is rubescent and air-supply arrangement air leakage phenomena, and tuyere small sleeve need to be replaced, blast furnace process vanadium titanium during replacement The process of magnetic iron ore needs damping down, and blast fumance is impacted and consumes a large amount of spare parts costs;Meanwhile the frequent damping down of blast furnace Also the stabilization of the working of a furnace can be unfavorable for and the conjunction of Gas Flow is now distributed.In addition, during blast furnace staying, air-supply blowing temp reduces, precooling Shrinking, there is parsing with tuyere small sleeve sealing surface in blowpipe of blowing, reason of being conducted oneself with dignity due to air-supply blowpipe, causes air-supply blowpipe offset, After furnace compound wind, air-supply blowpipe leaks out with tuyere small sleeve sealing surface, and there are security risk, needs damping down to reset.
Utility model content
In view of this, this application provides a kind of air-supply arrangement for smelting vanadium-titanium magnetite by blast furnace, the air-supply dress Put and extend the small service life in air port, reduce the damping down of smelting vanadium-titanium magnetite by blast furnace process.
To solve above technical problem, technical solution provided by the utility model is that one kind is used for blast furnace process v-ti magnetite The air-supply arrangement of ore deposit, including tuyere big sleeve, tuyere medium sleeve, tuyere small sleeve and air-supply blowpipe, in the tuyere big sleeve, the air port Set is connected with the tuyere small sleeve successively undergauge, and the air-supply blowpipe front end is connected with the tuyere small sleeve tail end, tuyere big sleeve Fixed block is internally provided with, circular arc bracket, the upper end of the circular arc bracket and the air-supply blowpipe are fixedly installed on the fixed block It is in contact;The air-supply blowpipe front end on the end face of the tuyere small sleeve tail end connecting pin with being provided with elastic seal ring;It is described Air-supply blowpipe front end sets cyclone.
Preferably, the affixed pull rod in the rear end of the fixed block.
Preferably, the circular arc bracket is trapezoidal perpendicular to the section of the air-supply blowpipe center line.
Preferably, the elastic seal ring includes annular groove and elastic sealing element, and the annular groove is blown arranged on air-supply Pipe front end surface, is embedded the elastic sealing element in the annular groove.
Preferably, the elastic sealing element is graphite stainless steel spirotallic gasket.
Preferably, the cyclone is ceramic material.
Preferably, the cyclone center is cylindrical type ventilating duct, and the cyclone outer shroud is to incline along circle to equally spaced The guide vane tiltedly set.
Preferably, the angle of inclination of the guide vane is 6~20 °.
Preferably, it is small set passage of blowing on the inside of the small set of air-supply.
Preferably, ceramic lining-tube is set on the inside of the small set passage of the air-supply.
Preferably, the small set passage of the air-supply is consistent with the center line of the air-supply blowpipe.
Compared with prior art, its detailed description is as follows by the application:
The application sets fixed block and circular arc bracket to play a supportive role air-supply blowpipe, avoids air-supply blowpipe dead weight reason from making Into the offset of air-supply blowpipe, the front and back position of fixed block is also adjusted by the affixed pull rod in the rear end of fixed block, so as to adjust circular arc The front and back position of bracket, so that the upper-lower position of air-supply blowpipe is adjusted, situation of leaking out caused by reducing air-supply blowpipe position offset; Meanwhile air-supply blowpipe front end and the end face of tuyere small sleeve tail end connecting pin are sealed using elastic seal ring, effectively avoid air port small Leak out caused by covering pre- cold events and air-supply blowpipe position offset, reduce the damping down for smelting vanadium-titanium magnetite by blast furnace.
The small set passage of the application air-supply is consistent with the center line for blowpipe of blowing, and reduces resistance of the tuyere small sleeve passage to hot wind Gear, reduces abrasion of the hot wind deflecting to tuyere small sleeve.Small set passage inner side setting ceramic lining-tube of blowing is further, and it is small to extend air port Cover service life.
The application air-supply blowpipe front end sets cyclone, and a part of hot wind is penetrated by cyclone center circle column type ventilating duct Stream Muddy-water is moved, and another part hot wind does swirling motion after entering small set of blowing, and reduces the pressure that tuyere small sleeve is subject to, and it is small to extend air port Service life is covered, reduces the damping down of smelting vanadium-titanium magnetite by blast furnace process.
