Description
Technical field
The utility model relates to a kind of iron mineral preparation equipment, particularly relates to a kind of technical equipment that is applicable to the ore dressing of refractory iron ore thing.
Background technology
The principle of magnetizing roast is the process that under the heated condition volatile substance in the refractory iron ore thing (carbon dioxide, water) is removed or di-iron trioxide wherein is reduced into tri-iron tetroxide.The magnetizing roast process of traditional processing technology realizes in shaft kiln, rotary kiln.
The shaft kiln production technology is relatively backward, is easy to generate burning and underburnt, and the iron ore reduction rate is low, can not handle the raw material that is prone to hot powder phenomenon-tion as limonite, siderite one class.
The rotary kiln production technology has overcome the above-mentioned shortcoming of shaft kiln to a certain extent, but hear rate is very high, has ring formation, skinning simultaneously, production operation problems such as frit occur.
No matter shaft kiln or rotary kiln, conduct heat and mass transfer velocity slowly, adjustment is long lag time, iron oxide magnetization rate does not reach more than 98% in the calcining, the production capacity of single device is all not really high.
Summary of the invention
The purpose of this utility model provides a kind of suspending magnetization roasting furnace, is used for from refractory iron ore material preparation iron ore concentrate calcining the iron ore rate of recovery of follow-up magnetic separation operation being improved greatly.
The technical scheme that adopts is:
Suspending magnetization roasting furnace comprises suspend magnetization oven body and separator.The magnetization furnace body inwall that suspends is provided with refractory lining, and the top material outlet of the magnetization furnace body that suspends is connected with the separator material inlet by delivery channel.The furnace roof that magnetizes furnace body that suspends is open hearth top or arch stove.The bottom of suspension magnetization stove is a cone table, and cone table is connected with a vertically disposed conduit solid welding.The magnetization furnace body that suspends is provided with material inlet, and is connected with the heat supply inlet of auxiliary burner and heat supply burner.The separator upper end is provided with exhaust outlet, and its lower end is fixed with drainage conduit, is equiped with the expanding type voltage-stablizer in the drainage conduit upper end.
The middle part of above-mentioned suspending magnetization roasting furnace body can be made into the saddle type structure of indent, can fixedly connected with a horizontally disposed tangent line conduit in above-mentioned conduit lower end, and combustion air is introduced from vertical conduit or tangent line conduit.Flame and combustion product and from entering the material direct contact heat transfer in the stove, flue gas band material suspended rising and are flow to delivery channel and enter the separation chamber and separate, and the separation chamber is made up of cyclone separator and expanding type voltage-stablizer.
The basic operational functions of suspending magnetization roasting is: refractory iron ore thing grinding to below particle mean size 250 orders, is sent into suspending magnetization roasting furnace and carried out magnetizing roast, and the crystallization water and the carbon dioxide removed in the mineral are made iron ore concentrate.If other impurity too much in the raw ore, grade is lower, then the calcining that magnetizing roast is obtained send magnetic separator to select iron ore concentrate behind ore grinding.
From the red mud of nonferrous metallurgy waste residue or the discharge of alumina producing factory, extracting in the technology of iron ore concentrate, we have adopted high intensity magnetic separation → filtration → drying and magnetizing roast → ore grinding → low intensity magnetic separation → flotation → dealkalize → filtration to wait several operations, though the flow process complexity still has considerable economic and bigger environmental protection social benefit.And suspending magnetization roasting furnace of the present utility model is the key equipment in the whole technical process.
The utlity model has following advantage:
1, is widely used in all kinds of iron-bearing minerals, refractory minerals such as bag siderite, complicated heterogeneous iron ore, and the magnetizing roast of mine tailing, slag and red mud the like waste.
2, granular material is suspended in and carries out quick caloic transmission and drastic reduction reaction in the air-flow, and gained calcining magnetic susceptibility height is better than legacy equipment.
3, equipment is easy to maximize, and separate unit stove production capacity can reach 2,000,000 tons of calcining/years, is several times as much as other known device.
