Description
Technical field
Refractory material production is the utility model is related to, it is more particularly to a kind of to produce extra light calcined magnesia using magnesite tailings
Device.
Background technology
The magnesite of the preferable grade of China's magnesia (MgO) content more than 46.5% has remained little.It is a large amount of low-grade
Ore and magnesite muck need to make full use of.
At present, the conventional legacy equipment of China's production extra light calcined magnesia has light-burned shaft furnace, rotary kiln, fluidized kiln, suspension
Roaster, multihearth roaster and reflecting kiln, calcining mineral structure is required, and the powdery sieved can not enter kiln recycling,
Waste of resource, it is block and the control of fine granularity calcination time is improper to enter the inequality of kiln, underburnt or burning easily occurs, outside process dust
Pollution environment is let out, hydration activity is unstable, and fine grinding, classification are needed after burning, and the moisture absorption and secondary pollution, product easily occurs in subsequent process
It is low, of poor quality.There is major defect in above equipment, it is difficult to complete mine tailing and the outer fine ore high-value-use of level, cause the wasting of resources, sternly
Weight welding, it is difficult to meet environmental protection, energy-saving and emission-reduction and reduce the requirement such as operating cost.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of produces extra light calcined magnesia using magnesite tailings
Device, solves how magnesite powder is decomposed to form rapidly light-burned activated magnesia in the state of suspension.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of device that extra light calcined magnesia is produced using magnesite tailings, including fuel gas hot-blast stove, filter cake feeder, flash distillation
Drying machine, cyclone separator, sack cleaner, preheater, screw feeder, flash circulation flow dynamic furnace, gas-solid separator,
Somehow storehouse, air cooling system and product feed bin, the fuel gas hot-blast stove connects filter cake feeder, and the connection flash distillation of filter cake feeder is dry
Dry machine, flash dryer outlet the first cyclone separator of connection and the first sack cleaner, the first sack cleaner and preheater
Connection, preheater connect flash circulation flow dynamic furnace, flash circulation flow dynamic furnace outlet connection gas by screw feeder
Solid separator, gas-solid separator connects respectively somehow storehouse and the second sack cleaner, somehow storehouse connects air cooling system, air cooling
System connects the second cyclone separator and the second sack cleaner, the second sack cleaner connection product feed bin, the flash rotation
Flowable state calcining furnace is connected by pipeline waste heat introducing flash dryer.
The first described sack cleaner and the second sack cleaner are provided with high-pressure suction fan.
Who described bin bottom is provided with discharge valve.
Described air cooling system connects air-cooled pipeline.
Compared with prior art, the beneficial effects of the utility model are：
The utility model realizes that mine tailing powder dinectly bruning produces magnesia.Low-grade scrap feed material is suitable for, it is reclaimed
Rate reaches 100%, realizes mine tailing zero-emission.Calcining heat, air quantity, charging rate are controllable, no dust leakage, gas-solid mixing, heat
Abundant, moment calcining is decomposed, product is without burning without underburnt, and product quality amount is stable, and product recovery rate is up to 99.9%, building ring
Border is cleaned, and waste heat is recycled utilization, makes full use of thermal source to form energy-efficient equipment.
