A kind of waste aluminum and aluminum ash recycling system

Abstract

The invention belongs to metal melting and processing systems and particularly discloses a waste aluminum and aluminum ash regeneration system which comprises a first stock bin, a rotary furnace, a lifting mixer, an aluminum slag chute, a pool, a cooling barrel, a hoist, a second stock bin, an aluminum liquid chute, a holding furnace, an ingot casting machine, an automatic ingot stacking machine, a dust collector and a controlling system. The waste aluminum and aluminum ash regeneration system has the following advantages that 1, the automation degree is high; 2, the equipment maintenance cost is low due to the fact that a forklift is not used in the whole production process; 3, fully-closed production is beneficial to better environmental protection in dust control; and 4, the recovery rate of waste aluminum and aluminum ash can be increased.

Description

technical field [0001] The invention belongs to a metal smelting and processing system, in particular to a recycling system for waste aluminum and aluminum ash. Background technique [0002] Due to the relative lack of high-quality aluminum ore resources in my country, only Shanxi, Guangxi, Guizhou, Henan and Jiangxi have relatively rich bauxite ore. The production of aluminum metal from alumina consumes a lot of energy and the process is complicated, and the production of electrolytic aluminum metal is still slow It cannot meet the ever-growing construction and development requirements, so aluminum resources in some places are mainly obtained from recycled waste aluminum. The waste slag is recycled and smelted to produce aluminum alloys, and 10% to 20% of aluminum ash slag will be produced at the same time. Remelting also produces about 2% aluminum ash. A large amount of aluminum ash is produced every day in the country. [0003] How to recycle and reuse such a large amount...

AI Technical Summary

Problems solved by technology

[0004] The collection and reprocessing process of traditional scrap aluminum and aluminum ash is divided into multiple workshops for production, and the transportation of materials between multiple workshops is carried out manually. The production efficiency is low, and most of them are small crucibles (not allowed by the national policy) and recycling. Converter production

[0005] The working status of the existing rotary furnace is basically level. The angle of the rotary furnace can only be adjusted between 0°~35°. The slag discharge and water discharge are not thorough enough. The stirring of the materials in the furnace can only be carried out by rakes and forklifts; improper operation is easy Damage to rotary kiln and forklift

[0006] In addition, the motor and gear transmission parts are all arranged on one side of the cylinder, which is driven by friction, so the rotation of the cylinder is not stable enough
