Abstract
The utility model discloses a kind of improvement blast furnace processing antimony or antimony gold concentrate, this improvement blast furnace comprises shaft, external crucible, slag road and cupola well, and described slag road is arranged on the cupola well wall place of 120mm ~ 150mm bottom cupola well distance cupola well; This improvement blast furnace can be effectively energy-conservation, and be conducive to being separated of the sedimentation of gold and antimony and the three-phase of slag, antimony sulfonium, your antimony.
Description
Technical field
The utility model relates to a kind of improvement blast furnace processing antimony or antimony gold concentrate, belongs to stibium fire field of metallurgy.
Background technology
Before the band of antimony, bed blast furnace volatile smelting is the novel process that China tested successfully the sixties in 20th century, and its melting characteristics is that volatile smelting realizes under the conditions such as low column, the thin bed of material, high coke yield, hot-top.In fusion process, the antimony sulfide volatilization oxidation in antimong-containing material, carry out sedimentation layering with together flowing into external crucible by cupola well after gangue slag making and release after gold-bearing material melting, tentatively realize the separation of gold, antimony, main volatility product weisspiessglanz is collected in condenser system.
With the control containing antimony gold that the economic and technical norms that the blast furnace of external crucible is important are exactly slag, antimony sulfonium, must the antimony gold amount that contain of slag, antimony sulfonium be controlled to low as much as possible, thus improve the direct yield of valuable metal.Blast furnace with external crucible in prior art, bottom slag road and cupola well, (siege) at grade, in smelting process, the melt of generation all flows into external crucible rapidly, external crucible metal separation weak effect, in body of heater, thermal equilibrium maintenance is poor, consumption of coal is large, and blast furnace is bad to be opened, and tuyere turns black, the fire in a stove before fuel is added is bad, and freezing of a furnace occurs often.
Utility model content
Exist in fusion process for the blast furnace with external crucible in prior art and there is metal separation weak effect, a series of problems such as coal consumption amount is large, the purpose of this utility model is to provide a kind of energy-conservation, improvement blast furnace of strengthening metal separation effect.
The utility model provides a kind of improvement blast furnace processing antimony or antimony gold concentrate, comprises shaft 1, external crucible 2, slag road 3 and cupola well 4, and described slag road 3 is arranged on the cupola well wall place of cupola well 4 apart from 120mm ~ 150mm bottom cupola well.
Improvement blast furnace of the present utility model only needs to deepen 120mm ~ 150mm in existing traditional burner cylinder bottom portion to the setting of cupola well and just can realize.
The beneficial effects of the utility model: the blast furnace Shi Jiangzha road of band external crucible of the prior art is arranged on bottom cupola well, with bottom cupola well at grade, object is in order in smelting process, the molten mass in body of heater is made all to flow into external crucible rapidly, three phase separation is carried out at external crucible, but this design of the blast furnace of band external crucible is also not suitable for practical application in industry, as bad in there is three phase separation effect, in body of heater, thermal equilibrium maintenance is poor, consumption of coal is large, and blast furnace is bad to be opened, and tuyere turns black, the fire in a stove before fuel is added is bad, and freezing of a furnace occurs to wait series of problems often.The utility model efficiently solves the problems referred to above by carrying out simple improvement to cupola well.Cupola well is deepened to a certain extent by the utility model, certain useful volume has been had bottom cupola well, high-temperature fusant can be made to stay for some time bottom cupola well, for maintenance thermally equilibrated in cupola well is laid a good foundation, the strong profit of the red-hot melt retained bottom cupola well melts with the acceleration entering stove material, reach and maintain thermal equilibrium in stove, reduce the object of coal consumption, and be more conducive to the operation of charge melting continuity.Simultaneously, high temperature melting melt body is introduced into bottom cupola well, and molten mass is in metastable state bottom cupola well, be conducive to being separated of the sedimentation of gold and antimony and the three-phase of slag, antimony sulfonium, your antimony, for the further separation of external crucible creates conditions, reduce the content of antimony and gold in slag and antimony sulfonium, prevent the situations such as freezing of a furnace from occurring simultaneously.
Accompanying drawing explanation
[Fig. 1] is the blast furnace of band external crucible of the prior art:
[Fig. 2] is the blast furnace of the band external crucible after improvement:
1 be shaft, 2 be external crucible, 3 be slag road, 4 for cupola well.
Embodiment
Following examples are intended to protection domain of the present utility model of making an explanation to the utility model content, instead of limit by reference to the accompanying drawings.
Embodiment 1
The utility model will be deepened bottom the blast furnace well of band external crucible to arrive from Guo Zha road base plane 140mm, and other structure of stove is constant.
Adopt the blast furnace of band external crucible to the melting of antimony concentrate: in stove, blast air, coking coal burning provides heat, and the antimony sulfide in concentrate at high temperature evaporates into gaseous state, gaseous state Sb
2s
3generate weisspiessglanz with the oxygen reaction in air again, the gangue in antimony concentrate and iron ore and refined lime generation slag making are reacted, and generate SiO
2-FeO-CaO ternary slag system, finally makes antimony be separated with gangue.And the gold in antimony gold concentrate can not volatilize in blast furnace, but melting under the hot conditions of cupola well.Molten mass together flows into bottom cupola well with gangue slag making, and molten mass stays for some time in cupola well, heat energy is made full use of the mineral aggregate passed to and newly add on the one hand, gold and antimony alloy is precipitated on the other hand, forms the thing phase of slag, antimony sulfonium, three layers, your antimony.
Chen Zhou smeltery, Xinshao cupola well is by after the method transformation, temperature of the furnace hearth obviously strengthens control ability, the working of a furnace also takes a turn for the better to some extent, indices is all normal, burnt consumption obviously reduces, when processing height silica flour ore deposit, Longshan and lump ore (dioxide-containing silica is all more than 18%), also seldom there is the situation of freezing of a furnace and scaffolding.Thus, the high siliceous antimony gold concentrate of melting, also to accomplish not only soon, not only good but also economize, energy consumption reduces greatly.In 2012 years, air blast oven coke consumption is reduced to 313.29 kilograms, concentrate per ton every year, lower than 2011 42.37 kilogram per tonne concentrate, and 12 years single month burnt consumption is minimum reaches 230 kilogram per tonne concentrate.In the current year, burnt consumption continues to maintain lower level, far below consumption burnt before transformation.
In April, 2013, when because of the twice interim blowing out of bosh radiator leak blast furnace, its of that month treatment capacity is 1636.631 tons, and burnt consumption is 265.22 kilogram per tonne concentrate.
