Cleaning, floating and drying integration pre-treating method for scrap aluminum

Abstract

The invention relates to a cleaning, floating and drying integration pre-treating method for scrap aluminum. The method is characterized in that firstly, pretreatment is carried out, and a scrap aluminum material is cleaned through a two-time rinsing system, so that impurities on the surface of the scrap aluminum material are removed; through one-time floating, magnesium materials and other impurities in the scrap aluminum material are suspended on a liquid surface through one-time floating and then are scraped out; aluminum materials in the scrap aluminum material are screened out through two-time floating; and finally, drying is carried out, the floated aluminum materials are dried through recycled waste heat, and it is ensured that the water content in the aluminum materials is lower than 0.3 percent. The method has the advantages that through cleaning, floating and drying integration treatment, the scrap aluminum material enters a machine device to be cleaned, floated and dried, and a clean pure aluminum material is output; no any repeated production links exist in the method, and therefore before being put into a furnace, the aluminum materials are clear in chemical component and low in water content, and energy consumption is saved; and a smelted renewable aluminum alloy ingot is high in quality.

Description

technical field [0001] The invention relates to a waste aluminum recovery process, in particular to a waste aluminum pretreatment method in the waste aluminum recovery process. Background technique [0002] Recycled aluminum is aluminum ingots that meet the requirements of various standards and are produced by smelting and preparing recycled aluminum scrap parts or scraps and scrap aluminum wires in the process of producing aluminum products as the main raw materials. This kind of aluminum ingot adopts recycled waste aluminum, which has lower production cost, and it is the reuse of natural resources, which has strong vitality, especially in today's rapid development of science and technology and continuous improvement of people's living quality, the product update The frequency of replacement is accelerating, and the recycling and comprehensive utilization of waste products has become an important issue for the sustainable development of human beings. Therefore, the recyclin...

AI Technical Summary

Problems solved by technology

Most of the current pretreatment methods are manually operated, sorted by hand, and then cleaned. The work efficiency is low, the labor intensity is high, and it cannot be adapted to large-scale production.

[0005] Although some enterprises carry out mechanized pretreatment, cleaning, flotation and drying are carried out separately. On the field, some don't even dry

And only one flotation is carried out, and the sorting of raw materials is not thorough, so there are defects in complex components and the inability to accurately control the chemical composition of aluminum ingots
