Alumina producing Bayer process has the characteristics of flow is simple, operation is convenient, product quality is high.Oxygen is produced in Bayer process
During changing aluminium, it is one of important process that supersaturated sodium aluminate solution addition crystal seed, which carries out decomposition reaction, commonly referred to as " brilliant
Kind of decomposition process ", it is that substantial amounts of aluminium hydroxide is added in supersaturated sodium aluminate solution as crystal seed referred to as " kind operation break-down ",
Carry out the induction crystallization of aluminum hydroxide crystals and grow up, decompose supersaturated sodium aluminate solution, after decomposition reaction continues 35~75h
Obtained aluminium hydroxide slurry, carry out solid-liquor separation and be classified by granular size, the coarse granule hydroxide of gained after decomposition
Aluminium is scrubbed, dehydration, and roasting obtains alumina product；Fine grain aluminium hydroxide, which returns to decomposition process, to be continued to be used as crystal seed.
Therefore, decomposition of crystal seed is one of critical process for controlling alumina product technical-economic index.Supersaturated sodium aluminate solution crystal seed
Equipment employed in decomposition process is referred to as " decomposition of crystal seed groove ", referred to as " seed precipitation tank or decomposer ", production process be typically by
Several to more than ten seed precipitation tank is cascaded progress.
For a long time, in sodium aluminate solution crystal seed decomposition process, integrally stirred using in each seed precipitation tank always
The decomposition technique method of dynamic slurries, i.e. complete mixing flow.At present, it is a kind of conventional agitating mode that the full puddling of machinery, which mixes isolation,.
It is to erect to set a mechanical stirring device with multilayer particular design blade uninterrupted in decomposer that mechanical full puddling, which is mixed,
Ground is stirred.At present, churned mechanically driving force derives from motor.Because cell body is huge, 14 meters of diameter, high 35 meters
Decomposer just needs the stirring motor and gearbox of one 75 kilowatts of configuration, and cost costly, not only needs to consume a large amount of electric energy,
And maintenance and repair is costly.In addition, common stirring decomposition technique method can cause mutually to mix between upper and lower layer liquid
(being commonly called as " short circuit "), the sodium aluminate solution degree of supersaturation being just transported in decomposer is reduced, declines reaction efficiency, while by force
Strong complete mixing flow agitation also result in the product particle degree that crystallization separates out and decline.
The decomposer of maximization, diameter reach 14 meters, up to 35 meters, and top diameter of stirring paddle is 8.4 meters, bottom agitating paddle
A diameter of 10 meters, operation moment of torsion is very big, to torsion output equipment and severe to the fulcrum requirement condition of connection blade and rotating shaft
Carve, complex process, cost of manufacture is high.

Pipe, blade cavity, finally spray and flow out from hole.Propulsive thrust is formed from the air-flow of hole outflow, propulsive thrust acts on blade, made
Obtain ventilation axle of motor to rotate about the axis thereof, blade is stirred slurry and is stirred.In addition, the air-flow of injection produces bubble to slurry, it is local
Pulp density step-down, local slurry flowing, air-flow make further stirring to slurry.
Using technical solution of the present invention, have the advantages that：
1. the aluminum oxide decomposer stirring system of the present invention using compressed air as power resources, drives the wind stirring to fill
Put and carry out slurry stirring, equipment is succinct, and manufacturing cost is low, and maintenance maintenance expense is low, avoids the large scale equipment using high energy consumption, fortune
Row cost is low, good in economic efficiency.
2. slurry is locally purged from the compressed air stream that the blade sprays so that local pulp density is low, in slurry
Airflow stirring is partially formed, mixing effect is stronger, more preferable.
3. according to process requirements, the agitating paddle is added in different slurry aspects, realizes that different slurry aspect differences are stirred
Mix the technique effect of emergency.
4. traditional rotating shaft drives the drive manner of agitating paddle easily to cause to damage to agitating paddle fulcrum, fracture, the present invention
The wind stirring device of use, blade being acted directly on using the propulsive thrust of wind, agitating paddle fulcrum is small by the action effect of power,
Produce safer, more energy efficient.
