Description
Technical field
The present invention relates to a kind of blast furnace sinter mixing distribution device, belong to the improvement of blast furnace sinter distribution device structure.
Background technology
Sintering is as an important step of blast-furnace smelting promptly: iron-bearing material, coke powder, flux etc. are added aqua according to certain mixed; Through mixing, granulate compound cloth to sintering pallet; The coke powder in the compound is lighted through the negative pressure exhausting in the igniting back; The high temperature that the coke powder burning produces becomes agglomerate with compound fusing, bonding, and this process is referred to as sintering.
Because sintering production process is the negative pressure exhausting, just determined one of them important factor in order to be: the ventilation property of the compound of cloth to the sintering pallet, and the ventilation property of compound is decided by wherein the grain amount greater than 3mm.The effect that mixes in the sintering production process, granulates also is this.
The iron-bearing material that SINTERING PRODUCTION is used all be iron essence powder (< 0.074mm accounts for 65%); Account for 60-65% through the grain amount greater than 3mm in the back compound that mixes, granulates, how the cloth of not being damaged greater than the particulate material of 3mm in the compound is become the key of cloth to the sintering pallet.
Through to the discovering of the cloth form of sinter mixture in the present domestic large-type sinterer SINTERING PRODUCTION, mixture distributor general a large amount of use two kinds of basic forms are arranged: feed bin+cylinder+reflector (roll-type distributor); The cloth form of yaw belt+wide belt+roll-type distributor.
The problem of first kind of distributing mode existence is that compound is taken out of from feed bin when cylinder rotates; Wherein the material greater than 3mm is squeezed in the discharging process; Much mixing granulation produce＞granule materials of 3mm is squeezed broken; Afterwards ventilation property is poor to sintering pallet to cause material cloth, influences the yield and quality of agglomerate, and granulating loses meaning.How many material second kind of distributing mode when fluctuation takes place the compound amount, comes owing to do not cushion feed bin; Go out how many material; Cloth does not have regulating measure, is difficult to realize the level Four uniting and adjustment of yaw belt, wide belt, sinter machine, central cooler, and production control brings big difficulty to agglomerating.
Summary of the invention
The object of the present invention is to provide a kind of blast furnace sinter mixing distribution device; Make the cloth of sinter mixture not receive the big or small influence of the instantaneous material amount of compound; Can protect simultaneously the granule materials that causes in mixing, the pelletization to avoid destroying again, guarantee the ventilation property of compound and the sintering Rational Parameters of material, reduce " fringing effect " greater than 3mm; Make on the sintering pallet mixture distributor control more stable, more reasonable, improve sinter machine output, quality.
The objective of the invention is to realize like this; A kind of blast furnace sinter mixing distribution device; Comprise yaw belt, feed bin and wide belt; The discharge end of yaw belt is positioned at feed bin opening for feed top, and the discharge port antetheca bottom surface of feed bin lower end is protruding circular arc down, and said wide belt HI is arranged in the feed bin below.
As the improvement of apparatus of the present invention, the material metage transmitter is installed in feed bin, this transmitter links to each other with the buncher of wide belt through the PLC unit.
Distance H 1 between discharge port antetheca bottom, said feed bin lower end and the wide belt end face is less than the distance H 2 between discharge port two ends, feed bin lower end and the wide belt end face, H2/H1=2.5-3.
When apparatus of the present invention are used; Compound gets into feed bin through the yaw belt, when the compound in the feed bin reaches certainweight, regulates the frequency conversion of wide belt; Make wide belt running; Compound is hauled out the arc discharge port and is fallen on the roll-type distributor under the haul of wide belt, under the effect of roll-type distributor revolving force compound by cloth to sintering pallet.This kind distributing mode has combined the advantage of preceding two kinds of distributing modes, has avoided its shortcoming, makes that the cloth of sinter mixture is more reasonable, and advantage is following: 1, the feed bin of weighing, the volume 42m of the feed bin of weighing are set
3, range is the 0---70 ton, can a certain amount of compound of splendid attire, can play the effect of buffering materials flow; Avoided when fluctuation takes place compound material amount influence to cloth; 2, weigh through the automatic routine setting and be limited to 60 tons in the weighing of feed bin, rolling off the production line is 20 tons, when surpassing this value; Computingmachine is reported to the police automatically; Can in time regulate the speed of wide belt, avoid in the feed bin compound hole capital after selling all securities or overflow, be more prone to realize the level Four uniting and adjustment like this; 3, the feed bin discharge port of weighing is the arc discharge port; The compound that comes out also can keep " meniscus shape " of the thick intermediate thin in both sides; Make cloth also can keep " meniscus shape " of the thick intermediate thin in both sides to the compound on the sintering pallet; Avoided " fringing effect " in the sintering process, made sintering process, air quantity distribute, heat distribution is more reasonable.4, weigh that the discharge method of compound is the material drag mode in the feed bin; Because compound is hauled out by wide belt; Thereby avoided extruding to make the granule materials greater than 3mm in the compound be able to intact preservation, compound cloth has guaranteed air permeability and good after to the chassis, improves sintering character greatly.The novel sinter mixture distributing mode of this kind has overcome the shortcoming that conventional sinter mixture distributing mode exists; Designed the feed bin of weighing simultaneously with multinomial innovative function; Upper and lower limit to the compound amount is controlled, and adopts the material drag mode to haul out the mixing charge level of " meniscus shape " simultaneously, makes that the sinter mixture cloth is more reasonable; Eliminated " fringing effect " of sintering process, more helped the raising of sintering production capacity.
