Abstract

The invention discloses a secondary aluminum production system and method. The secondary aluminum production system comprises a crushing and sorting system I, a crushing and sorting system II, a paint removal system, a feeding system, a melting system, a refining system, a casting system and a waste gas treatment system. The crushing and sorting system I is connected with the paint removing system, the paint removing system is connected with the feeding system, the crushing and sorting system II is connected with the feeding system, the feeding system is connected with the melting system, the melting system is connected with the refining system, and the refining system is connected with the casting system. The waste gas treatment system is respectively connected with the crushing and sorting system I, the crushing and sorting system II, the paint removing system and the melting system; the removal rate of the surface coating of the waste aluminum is greater than 99%; the use of waste aluminum ring-pull cans is not reduced; the recovery rate of the waste aluminum ring-pull cans is greater than 96%; and the purity of the sorted waste aluminum ring-pull cans is greater than 98%. According to the secondary aluminum production system and method, the secondary aluminum production system and method is safe, environment-friendly and reasonable in configuration, and continuous and stable operation can be realized; and through the advanced crushing technology, continuous operation of the device can be achieved, and meanwhile the service life of the device is prolonged.

Description

technical field [0001] The invention belongs to the field of waste aluminum recycling, in particular to a production system and method for recycled aluminum. Background technique [0002] Aluminum is a recyclable resource, which can be divided into traditional primary aluminum and secondary aluminum according to different sources of raw materials. Traditional primary aluminum production uses bauxite as raw material, which is extracted into alumina by chemical methods, and then liquid electrolytic aluminum is obtained by electrolysis (aluminum water), aluminum water is cast into pure aluminum, or a small amount of other ingredients are added to become aluminum alloy. Recycled aluminum uses scrap aluminum as raw material, and refers to metal aluminum obtained through at least one casting or processing and recycling and treatment. The existing form of recycled aluminum is generally aluminum alloy. Contents of the invention [0003] In view of the defects existing in the prio...
