Abstract
The invention relates to a waste electric wire crushing and separation method and device. Firstly, raw electric wires are cut into short electric wire sections by using a cutting machine and mutual stripping between metal conductors and plastic shells is realized through difference of strength and sequence that a cutter acts on plastic and the metal conductors; for a small quantity of short electric wire sections with the metal conductors and the plastic shells are not automatically stripped, after primary separation and collection are conducted, the short electric wire sections are crushed into particles with certain grain size under the control of a screen to obtain metal and plastic mixture; and finally the metal and the plastic in the mixture are separated by using a separation device and then are collected. The method has the advantages of fewer steps and high efficiency, and is applicable to large-scale resource recovery of comparatively tidy waste electric wires. Moreover, a low-cost and high-performance electric wire and cable resource recovery device can be developed on the basis.
Description
Technical field
The present invention relates to a kind of cracking and sorting method and device of scrap electrical wires, belong to the metallo-plastic isolation technics in the resource recycling of mine, city.
Background technology
Along with developing rapidly of electric power and electronic enterprises, the scrap electrical wires cable produces in a large number.Containing a large amount of metals and plastics in electric wire, is the high added value article in the mine, city.By reclaiming metal and plastics resource in scrap electrical wires, metal core wire and plastic insulating layer are peeled off, and then metal is separated with plastic hybrid.
(the plastic layer external diameter 〉=3mm), the main wire stripper that adopts carries out the recovery that separates of heart yearn and plastics at present, and this method can obtain than more complete metal core wire and plastic casing for more regular thick line.But it is more to use wire stripper to exist human resources to take, and treatment effeciency hangs down inferior problem.Along with improving constantly of employment cost, promoting the use of of wire stripper is very limited.
Yet, with the resource recovery equipment of the scrap electrical wires of copper Mi Jiwei representative, need to heart yearn be pulverized fully by crushing mechanisms such as traditional one-level fragmentation, two-stage crushings.The problems such as when this method is directly used in the recovery of more regular thick line, exist energy consumption large, equipment attrition is serious, and the metals resources loss is serious, and efficient is low.
Therefore, it is significant for the efficient that improves the sector that for more regular thick line, the exploitation material recovery rate is high, energy resource consumption is low, manpower takies few scrap electrical wires cable cutting sorting technology and device.
Summary of the invention
In view of as above situation, the invention provides a kind of cracking and sorting method and device of scrap electrical wires, and develop based on this low cost, high performance electric wire resource recovery device.
Technical scheme of the present invention is as follows: at first utilize cutter that thick electric wire is cut to the electric wire pipe nipple, the dependence cutter is realized mutually peeling off of metal core wire and plastic casing to the priority difference of plastics and metal core wire active force, fail on a small quantity to realize that electric wire pipe nipple that metal core wire and plastics peel off voluntarily is after initial gross separation is collected, be ground into the particle of certain order number under the control of screen cloth, obtain metal and plastic hybrid, utilize at last separator that the metal in mixture is separated with plastics and collects.
A kind of cracking and sorting method of scrap electrical wires:
(1) for the thick scrap electrical wires of plastic outer layer diameter 〉=3mm, cut into stretched length less than the cut-out operation of the electric wire pipe nipple of 5mm;
(2) metal and the plastic grain mixture that operation (1) are obtained are delivered to the oscillating separator structure, separate the vibration separation circuit that obtains plastics, metal.
Realize the device of method of the present invention, at least by the cutter that scrap electrical wires is prescinded with the electric wire pipe nipple after prescinding is carried out the vibration separate equipment that metal separates with plastics and forms; Be provided with stationary knife and moving knife in cutter, stationary knife is arranged on to be sheared under charging aperture, and moving knife is arranged on axis, and the cutter outlet is arranged on the conveyer belt junction.
Be provided with deflector chute and guide roller in cutter charging place.
The top fed mouth can also be set on cutter top, and the cutter bottom arranges detachable screen cloth; Be provided with two symmetrical stationary knifes in cutter.
Described mesh size is in 1～3mm scope.
Above utilizing, device carries out the cracking and sorting method, and electric wire is cut into the electric wire pipe nipple after by the horizontal feed inlet importing, and gained metal core wire and plastic hybrid are delivered to vibration separate equipment, completes separating and collection of metal, plastics and unstripped electric wire pipe nipple.
Single core thick line pipe nipple of peeling off for failing or other electric wire pipe nipple after by the one-level crusher in crushing; close in the horizontal feed inlet situation at cutter; by the charging of top fed mouth; after the two-stage crushing of cutter by moving knife and stationary knife; the electric wire pipe nipple is ground into metallic particles and plastic grain; after gained metallic particles and plastic grain mixture pass through screen cloth, then be delivered to the vibration separator structure, complete thoroughly separating fully of scrap electrical wires metal and plastics.
Cracking and sorting method and the device of scrap electrical wires of the present invention, by controlling charging rate and guillotine cutting frequency, more regular waste and old thick electric wire is cut to stretched length less than 5mm, rely on cutter to realize that to the priority of plastic outer layer and metal core wire active force and difference in size it peels off mutually, and reach the purpose of plastics and metal separation by vibrosieve, the method step is few, efficient is high, and the resource that is applicable to more regular scrap electrical wires in enormous quantities reclaims.
