Device and method.
Background technology
Aluminium lime-ash is the accessory substance of aluminium and aluminium alloy smelting, and it is by groups such as aluminum oxide, metal aluminum or aluminum alloy, slag formers
Into.30 ~ 50kg aluminium lime-ash is produced by 1 ton of finished product aluminium ingot of production to calculate, China produces more than 100 ten thousand tons per year.In aluminium lime-ash because containing aluminium or
Aluminium alloy 10 ~ 80%, with very high recovery value.
Reclaiming aluminium from aluminium lime-ash both at home and abroad at present has hot absorption method and the class of cold conditions absorption method two.Hot absorption method be by
The aluminium lime-ash just clawed from smelting furnace is placed in the inclined revolution tank and stir-fried, and aluminium fully contacts generation with air
Thermit reaction, improves the temperature of aluminium to improve its mobility, under gravity, aluminium enriching and recovering.Hot absorption method is present
Aluminium scaling loss is serious, and metal recovery rate is low, and produces the flue gas of a large amount of fluorine-containing and chlorine in whipping process, and environment is caused seriously
Influence.The method of cold treatment aluminium lime-ash is to allow it to quickly enter cooling device, quick reduction aluminium ash temperature, and makes aluminium therein
Graininess is formed, is reclaimed using gravity separation method.But the aluminium that this method is obtained is mingled with seriously, and alum recovery efficiency is low.How
Efficiently, metallic aluminium in separation aluminium lime-ash is reclaimed in environmental protection turns into the emphasis that people study.
On October 28th, 2010, Zeng Dunwei etc. has applied for national inventing patent " a kind of grey re-smelting device of aluminium and its user
Method "（Application number：2010105227314）, disclose including pedestal, fry grey pot, agitating paddle fries the porose recovery aluminium of grey pot bottom
The equipment of metallic aluminium in ash.On December 4th, 2013, the big grades of Lei Wen have applied for a kind of national inventing patent " the grey recycling side of aluminium
Method "（Application number：2013106481674）, one kind is disclosed by frying grey pot and stirs hot aluminium ash, and the aluminium fusing in making aluminium grey is simultaneously
It is layered with slag.Above-mentioned patent is that the metallic aluminium in aluminium ash is reclaimed by the method for stirring, but has that the rate of recovery is low, work
The shortcomings of environment is poor.
On November 13rd, 2013, thank and just etc. applied for the national inventing patent resource utilization method of ash " a kind of aluminium "（Shen
Please number：2013105614857）, disclose a kind of by aluminium lime-ash is broken, grinding, vibratory sieve grade technique, reclaim metallic aluminium.
On November 20th, 2015, Chen Xiang has applied for clearly etc. national inventing patent " a kind of grey Comprehensive utilization method of aluminium ", discloses logical
The metallic aluminium crossed in grinding mode extraction aluminium ash.Above-mentioned patent is to use broken, ball milling, the method sorted by metallic aluminium and slag
Separation, but the problem of this method has high energy consumption, the rate of recovery is low.
On July 31st, 2015, Zhang Libo etc. has applied for a kind of national inventing patent " side of efficient comprehensive reutilization aluminium ash
Method "（Application number：201510458926X）, disclose and mixed by the aqueous solution of aluminium ash and certain pH value, in ventilation, stirring bar
Carry out intensified by ultrasonic wave under part and leach to reclaim aluminum oxide and villaumite, 1 h of reaction be in recyclable aluminium ash more than 98% villaumite and
More than 90% aluminum oxide.But this method is not related to the recovery of metallic aluminium in aluminium lime-ash.
On June 30th, 2015, Wu Zhi has applied for that by force etc. " one kind efficiently separates metallic aluminium in recovery aluminium ash to national inventing patent
Method "（Application number：2015103700946）, disclose strong acid and soak-bake and bank up with earth-crush the analysis of-release agent mixing-hot melt
