Abstract
The invention discloses 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 above feed bin opening for feed, and the discharge port antetheca bottom surface of feed bin lower end is lower convex circular arc, and said wide belt horizontal interval is arranged in below feed bin.The present invention is simple and reasonable, by improving feed bin discharge hole bottom shape and adopting wide belt material drag mode to haul out the mixing charge level of " meniscus shape ", make sinter mixture cloth more reasonable, eliminate " fringing effect " of sintering process, be more conducive to the raising sintering production capacity.
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
Sinter as blast-furnace smelting an important step namely: by iron-bearing material, coke powder, flux etc. according to certain ratio mixing add aqua, by mixing, granulate compound cloth on sintering pallet, lighted the coke powder in compound by negative pressure exhausting after igniting, compound melts by the high temperature that coke powder burning produces, bonding becomes agglomerate, and this process is referred to as sintering.
Because sintering production process is negative pressure exhausting, just determining one of them important factor in order is: cloth is to the ventilation property of the compound on sintering pallet, and the ventilation property of compound is decided by the grain amount being wherein greater than 3mm.The effect of mix in sintering production process, granulating also is this.
The iron-bearing material that SINTERING PRODUCTION uses is all Iron concentrate (<0.074mm accounts for 65%), account for 60-65% by the grain amount being greater than 3mm in mixing, rear compound of granulating, the cloth how particulate material being greater than 3mm in compound not to be damaged becomes the key of cloth to sintering pallet.
By finding the research of the cloth form of sinter mixture in current domestic large-type sinterer SINTERING PRODUCTION, what mixture distributor generally used in a large number has two kinds of basic forms: feed bin+cylinder+reflector (roll-type distributor); The cloth form of yaw belt+wide belt+roll-type distributor.
The first distributing mode Problems existing is that compound is taken out of from feed bin when drum rotating, the material being wherein greater than 3mm is squeezed in discharging process, the granule materials of the > 3mm much produced at mixing granulation is squeezed broken, cause poor air permeability after on material cloth to sintering pallet, affect the yield and quality of agglomerate, granulate and lose meaning.How many second distributing modes, owing to not having buffer bin, when mixing doses and fluctuation occurring, expects, go out how many material, cloth does not have regulating measure, is difficult to the level Four uniting and adjustment realizing yaw belt, wide belt, sinter machine, central cooler, brings larger difficulty to the production control of sintering.
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 by the impact of the instantaneous doses size of compound; the granule materials being greater than 3mm caused in mixing, pelletization can be protected again from destruction simultaneously; ensure that the sintering parameter of the ventilation property of compound and material is reasonable; reduce " fringing effect "; mixture distributor on sintering pallet is controlled more stable, more reasonable, improve sinter machine Yield and quality.
The object of the present invention is achieved 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 above feed bin opening for feed, the discharge port antetheca bottom surface of feed bin lower end is lower convex circular arc, and said wide belt horizontal interval is arranged in below feed bin; Distance H1 between discharge port antetheca bottom, said feed bin lower end and wide belt end face is less than the distance H2 between discharge port two ends, feed bin lower end and wide belt end face, H2/H1=2.5-3, in feed bin, be installed with material metage sensor, this sensor is connected by the buncher of PLC with wide belt.
When apparatus of the present invention use, compound enters feed bin by yaw belt, when the compound in feed bin reaches certainweight, regulate the frequency conversion of wide belt, wide belt is operated, compound, under the haul of wide belt, is hauled out arc discharge port and is fallen on roll-type distributor, under the effect of roll-type distributor revolving force compound by cloth on sintering pallet.This kind of distributing mode combines the advantage of first two distributing mode, avoids its shortcoming, and make the cloth of sinter mixture more reasonable, advantage is as follows: 1, arrange weighing silo, the volume 42m of weighing silo
3, range is 0---70 ton, can a certain amount of compound of splendid attire, can play the effect of buffering stream; Avoid the impact on cloth when fluctuation occurs compound doses; 2, the weighing upper limit arranging weighing silo by automatic routine is 60 tons, and rolling off the production line is 20 tons, when exceeding this value, computer automatic alarm, the speed of wide belt can be regulated in time, avoid compound hole capital after selling all securities or spilling in feed bin, be more prone to like this realize level Four uniting and adjustment; 3, weighing silo discharge port is arc discharge port, compound 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 sintering pallet, avoid in sintering process " fringing effect ", make sintering process, allocation of the amount of air, heat distribution is more reasonable.4, in weighing silo, the discharge method of compound is material drag mode, because compound is hauled out by wide belt, avoid extruding thus make the granule materials being greater than 3mm in compound be able to intact preservation, ensure that good ventilation property after on compound cloth to chassis, greatly improve sintering character.This kind of novel sinter mixture distributing mode overcomes the shortcoming that conventional sinter mixture distributing mode exists, devise the weighing silo with multinomial innovative function simultaneously, the upper and lower limit of mixing doses is controlled, adopt material drag mode to haul out the mixing charge level of " meniscus shape " simultaneously, make sinter mixture cloth more reasonable, eliminate " fringing effect " of sintering process, be more conducive to the raising sintering production capacity.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1 is main TV structure schematic diagram of the present invention;
Fig. 2 is the side-looking structural representation of feed bin of the present invention.
Embodiment
A kind of blast furnace sinter mixing distribution device, as shown in Figure 1 and Figure 2, comprise yaw belt 1, feed bin 2 and wide belt 4, the discharge end of yaw belt 1 is positioned at above feed bin 2 opening for feed, the discharge port antetheca bottom surface of feed bin 2 lower end is lower convex circular arc, and said wide belt 4 horizontal interval is arranged in below feed bin 2.
In feed bin 2, be installed with material metage sensor 3, this sensor 3 is connected with the buncher of wide belt 4 by PLC 5.The weighing upper limit being arranged weighing silo by automatic routine is 60 tons, and rolling off the production line is 20 tons, and when exceeding this value, computer automatic alarm, automatically can regulate the speed of wide belt 4 in time, avoid compound hole capital after selling all securities or spilling in feed bin.
Distance H1 between said discharge port antetheca bottom, feed bin 2 lower end and wide belt 4 end face is less than the distance H2 between discharge port two ends, feed bin lower end and wide belt end face, H2/H1=2.5-3.By improving feed bin discharge hole bottom shape and adopting wide belt material drag mode to haul out the mixing charge level of " meniscus shape ", make sinter mixture cloth more reasonable, eliminate " fringing effect " of sintering process, be more conducive to the raising sintering production capacity.
