Embodiment 1

[0024] A process for recovering residual aluminum shavings, comprising the following processing steps:

[0025] Step 1: Select the raw material, place the aluminum chips inside the magnetic separator, use the magnetic separator to magnetically separate the aluminum chips, so as to remove the internal iron-containing impurities, and press the removed iron-containing debris Block treatment, make it form a brick structure for accumulation, and place it in the screen for cleaning. After the aluminum scrap is washed by a high-pressure water source, it is placed inside the drying box, and the aluminum scrap is dried by circulating hot air;

[0026] Step 2: raw material pretreatment, place the aluminum chips obtained in step 1 in a heating box, use the heating tube inside the heating box to heat the aluminum chips, and when the inside of the heating box is heated to 40 ° C, a heating material is formed, of which According to the actual situation, the size of the raw materials is sort...

Abstract

The invention discloses an aluminum scrap residue recovery treatment process, and specifically relates to the field of waste aluminum recovery. The process includes the following processing steps: rawmaterial selection, raw material pretreatment, stamping treatment, aluminum scrap crushing, dilute sulfuric acid reaction, and hydrogen purification. Through the overall design, compared with the prior art, the process has the advantages that the heating temperature is appropriate, aluminum scraps are cleaned and screened to remove impurities in the aluminum scraps, the aluminum scraps are pre-heated to soften the interior structure of the aluminum scraps, the aluminum scraps in different sizes are divided into different levels and stamped by a stamping machine to form a flake structure, thenthe flaky aluminum scraps are crushed by a crushing machine to form aluminum scrap powder, dilute sulfuric acid is used for reacting with the aluminum scrap powder to form aluminum sulfate precipitate for recovery utilization, the utilization rate of the aluminum scraps is effectively increased, the wasting of resources is avoided, and the process conforms to the development concept of energy conservation and environment protection of modern society.

Description

technical field [0001] The invention belongs to the technical field of recycling waste materials, and in particular relates to a process for recycling and treating residual aluminum chips. Background technique [0002] Aluminum products made of aluminum and other alloying elements. It is usually processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then processed by cold bending, sawing, drilling, assembling, and coloring. The main metal elements are Aluminum, together with some alloying elements, improves the performance of aluminum materials. When processing operations in aluminum material production workshops, a large amount of aluminum scrap waste will be generated, which needs to be recycled. [0003] However, in actual use, general aluminum scraps are collected directly for garbage disposal, and are not subjected to secondary processing and utilization, thereby greatly reducing the utilization rate of aluminum scraps.
