线缆的收受接管便是接纳必然的手艺手腕,使导体和外皮离开,而后接纳分选手艺把导体和外皮分选开,获得较纯洁的金属与塑料等,从而到达资本化的目标。 The recycling of cable is to use certain technical means to disengage the conductor and the outer skin, and then use the separation technology to separate the conductor and the outer skin, and get a more pure metal and plastic and so on, so as to achieve the purpose of resource. 经常使用方式有:燃烧法 The common methods are: incineration method 燃烧法普通是操纵电线电缆中塑料的可燃性,接纳燃烧的方式来收受接管电线电缆中的金属。这是一种初期原始的金属收受接管方式,现已被国度明令制止,是一种被裁减的金属收受接管方式。 Incineration usually takes advantage of the combustibility of plastics in wires and cables, and uses incineration to recover metals from wires and cables. This is an early primitive metal recovery method, which has been banned by the state and is a metal recovery method that has been eliminated. 剥线法 Stripping method 该种方式对大直径的线缆的拆解在工场中操纵较普遍。主动剥线机任务道理以下图所示,右滚轮步进机电动员上、下右滚轮将夹持的被加工线摆布挪动;裁刀步进机电动员上、下两裁刀向相反标的目的活动,经由过程节制上、下裁刀之间的位移,完成剥皮和裁线的功效; This method is widely used in factories for the disassembly of large diameter cables. The working principle of the automatic stripping machine is shown in the following diagram. The right wheel stepping motor drives the upper and lower right rollers to move the clipped machined line, and the cutter stepping motor drives the upper and lower two cutting tools to move in the opposite direction, and realizes the function of peeling and cutting by controlling the displacements between the upper and the lower cutting tools. 左滚轮步进机电动员上、下左滚轮将夹持的被加工线摆布挪动;扭线轮步进机电动员上、下左滚轮向相反标的目的前后活动,完成扭线功效。此中扭线轮与左滚轮在物理上是指统一滚轮。 The left roller stepping motor drives the upper and lower left rollers to move the clipped machined line, and the twisting wheel step motor drives the upper and lower left rollers to move to the opposite direction, and realizes the twisting function. The torsion wheel and the left roller refer to the same roller in physics. 该种方式针对大直径的线缆的拆解有较好的结果。但因为其野生依托性强,针对中小直径线缆的出产效力太低,主动化水平差,对线缆的范例的分选性差。 The method is effective for the disassembly of large diameter cables. However, because of its strong manual dependence, the production efficiency of small and medium diameter cables is too low, and the degree of automation is poor. 高温破裂法 Cryogenic crushing 韧性物料在破裂加工时会显现各类塑性、粘性和弹性行动。普通以为颗粒的破裂首要受以下三个身分的影响:温度、打击速率、粒度,这三个变量节制着破裂的产生和破裂水平。高温破裂的根基道理便是操纵制冷手艺使物资产生改性脆化而轻易被破裂。 Ductile materials exhibit various plastic, viscous and elastic behavior during crushing. It is generally believed that the crushing of particles is mainly affected by the following three factors: temperature, impact velocity and particle size, and these three variables control the occurrence and degree of breakage. The basic principle of low temperature crushing is to use refrigeration technology to make materials brittle and easy to be broken. 高温破裂手艺最早完成产业化是在1948年,今朝经常使用的制冷方式有2种:一是制冷剂制冷,二是氛围收缩制冷。 The cryogenic crushing technology was first industrialized in the 1948. There are 2 commonly used refrigeration methods: refrigerant cooling, and air expansion refrigeration two. 今朝,高温破裂手艺在废旧电路板、废旧线缆的破裂中获得了较好的操纵,在液氮冷却下,废旧电路板、废旧线缆变脆,很轻易破坏,可是高温破裂液氮冷却装配本钱较高。 At present, the crusher technology has been well applied in the breakage of waste circuit board and waste cable. Under the cooling of liquid nitrogen, the waste circuit board and the waste cable are brittle and easy to crush, but the cost of the cryogenic liquid nitrogen cooling device is high. 机器破裂分选法 Mechanical crushing and sorting method 机器破裂法首要包含破裂和分选两个单位。废旧线缆经破裂单位被分化成必然标准的颗粒单位,而后经分选单位把铜和塑料分选开从而获得纯洁的铜和塑料。 Mechanical crushing includes two parts: crushing and sorting. The waste cable is broken into a certain size unit through the crushing unit, and then the copper and plastic are separated by sorting unit to get pure copper and plastic.
