Distribution cabinet wire and cable metal recovery system

Abstract

The invention discloses a distribution cabinet wire and cable metal recovery system. Steps of S1, raw material finishing, S2, material cutting, S3, material cleaning, S4, low-temperature processing, S5, crushing processing and S6, material sieving are included. A low-temperature freezing mode is adopted to process a cable, the plastic skin of the cable becomes crisp under influences of the low temperature and can be separated from a metal wire easily, the diameter and the size of a cable are not limited, and thus, a complete metal wire can be obtained, the physical properties of plastic particles are not changed, and later material processing is more facilitated.

Description

technical field [0001] The invention belongs to the field of wire and cable recycling, and more specifically relates to a metal recycling system for wires and cables in a power distribution cabinet. Background technique [0002] With the continuous development of communication, electric power and other industries, the demand for the amount of metal wires is increasing. Due to the rapid replacement of new and old products, the amount of waste wire and cable recycling is increasing year by year, and its environmental pollution is also becoming more and more serious. The issue of recycling waste wire and cable has received more and more attention. At present, the recycling of waste cables mainly includes wire stripping machine technology, mechanical crushing and sorting technology, and heat recovery technology. The wire stripping machine technology mainly drives the clamped wire to move through the roller and the stepping motor, so as to realize cutting and peeling. It has req...

AI Technical Summary

Problems solved by technology

The wire stripping machine technology mainly drives the clamped wire to move through the roller and the stepping motor, so as to realize cutting and peeling. It has requirements on the diameter and size of the wire, which makes its applicability poor; the mechanical crushing and sorting technology is mainly the first The waste is decomposed into particle units of a certain size through the crushing unit, and then pure copper and plastics are obtained through the sorting unit, and the processing efficiency is low; thermal decomposition technology is the most widely used waste cable recycling technology so far. The process environment is carried out in a closed container, and the insulating sheath is heated and decomposed under a certain pressure. The final product is oil gas, which can be reused after conversion. Although the recovery effect is good, it has relatively large limitations.
