AI Technical Summary

Technical Problem

Existing copper scrap recycling and processing equipment suffers from problems such as easy leakage during material transfer, difficulty in cleaning copper buildup on the inner wall of the extrusion cylinder, easy rolling off of shaped copper blocks during transport, and poor coordination between processes, making it unsuitable for the high-efficiency recycling and processing of large quantities of copper scrap in copper tube milling production lines.

Method used

Design an integrated device for feeding, spun drying, and extrusion molding, including a screw conveyor, a spun drying component, an extrusion molding box, a pushing component, and a cleaning component, to achieve closed conveying, synchronous cleaning, and automated molding of copper chips. The spun dryer removes cutting fluid, the pushing component assists in discharging, and a limiting component prevents copper blocks from rolling off.

Benefits of technology

It enables fully automated continuous drying and molding of copper scrap, reducing production and maintenance costs, improving copper scrap recycling efficiency, eliminating safety and quality hazards associated with remelting, and increasing material utilization.

Abstract

This invention discloses a drying and forming device for copper scrap recycling, relating to the field of copper scrap recycling technology. The device includes an extrusion forming box and a screw conveyor for conveying copper scrap. The extrusion forming box contains a mold component to assist in extruding copper scrap into blocks, and a conveyor plate is provided on the extrusion forming box for conveying the formed copper scrap. This invention integrates feeding, drying, and extrusion forming into a single, coordinated operation. The closed conveying system prevents leakage and contamination from copper scrap and cutting fluid. The dried copper scrap has a low moisture content, eliminating safety and quality risks associated with remelting. The pushing process simultaneously drives a cleaning brush to clean the inner wall of the conveyor cylinder, and a separation tank screens broken copper, reducing downtime for cleaning and improving raw material utilization. An elastic limiting component on the conveyor plate buffers the copper blocks and prevents them from rolling back. The entire system operates fully automatically in a cyclical manner, producing dense and easily transportable formed copper billets, significantly improving copper scrap recycling efficiency and reducing production and maintenance costs.
