A device for recovering an aluminium alloy efficiently and immediately comprises a heating and heat insulating furnace, an aluminium ash collecting box and a control cabinet. During usage, a furnace lid is opened by the aid of the control cabinet, aluminium ash and aluminium slag are added to a graphite crucible in the middle of the heating and heat insulating furnace, 0.5-1.0 kg of a fluxing medium is added according to addition amounts of the aluminium ash and the aluminium slag, the furnace lid is closed, the temperature of the heating and heat insulating furnace is set to range from 745 DEG C to 755 DEG C on the control cabinet, the revolving speed of a driving motor II connected with the heating and heat insulating furnace is set to range from 650 rpm to 700 rpm, the pressure of ash discharge blowing pipes on left and right sides of the bottom of the heating and heat insulating furnace is set to range from 50 KPa to 70 KPa, and the treatment time is controlled to range from 6 min to 8 min. After completion, a plug on the heating and heat insulating furnace opened, recovered aluminium is directly used by the aid of a trough, the graphite crucible is taken out by the aid outer side hangers of the graphite crucible, and treated aluminium ash and aluminium slag are poured out. The device has the characteristics of low labor intensity, low environmental pollution and high recovery rate.
Description
technical field [0001] The invention relates to the field of aluminum alloy smelting, in particular to a device for efficient and instant recovery of aluminum alloy. Background technique [0002] Smelting is a necessary production process for the manufacture of aluminum alloy wheels for automobiles. The molten aluminum smelting process will produce 10-15% aluminum ash and aluminum dross, which contain about 25-35% recyclable aluminum alloys. At present, the recovery of aluminum alloy in aluminum ash and aluminum slag can be divided into two methods: cold extraction and thermal extraction. The so-called cold extraction means that the aluminum ash and aluminum slag are cooled to room temperature after being removed from the smelting furnace, the aluminum ash and aluminum slag are crushed with special equipment, and then sieved step by step with sieves with different meshes to sieve out the aluminum alloy particles for recycling Use; the so-called thermal extraction is to cont...
