Description
技术领域
本发明涉及一种手机塑胶机壳镭雕后残渣的清洗方法。
背景技术
中国专利公开号107400566A的《清除智能移动终端塑胶机壳残渣的清洗剂及清洗方法》专利中提到智能移动终端如手机塑胶机壳镭雕后的清洗工艺是先用清洗剂在超声清洗机内超声清洗掉塑胶机壳镭雕后的残渣，然后将该手机塑胶机壳放入装有超纯水或者自来水的多槽超声波清洗机内进行漂洗，最后将漂洗好的手机塑胶机壳加热烘干水分，达到手机塑胶机壳干净的目的。上述这种超纯水或者自来水超声漂洗工艺，其不足之处在于：由于用于手机塑胶机壳镭雕后残渣的清洗剂一般是由多种有机化合物配制而成的，清洗剂原液的COD值很高，高达105mg/L以上。手机塑胶机壳镭雕后的残渣经过清洗剂清洗后会有一定量的清洗剂残留在手机塑胶机壳上，当用超纯水或者自来水来漂洗手机塑胶机壳时，残留的清洗剂会不断进入漂洗槽。为了使手机塑胶机壳漂洗干净，会不断用水稀释漂洗槽液让漂洗槽液产生溢流，溢流的漂洗水会源源不断通过外接管路流向废水池而产生大量的漂洗废水，从机器往外流出的漂洗水的COD值一般高达103mg/L以上，很难达到排放的标准，若没有进行相关处理就直接排放到环境的话，将会出现严重的环境污染问题。

具体实施方式
本发明提出一种手机塑胶机壳镭雕后残渣的清洗方法，需要应用的清洗设备（如图1所示）包括有依次排列的减压真空清洗机1、超声波清洗机2和真空清洗干燥机3。
减压真空清洗机1包括有减压蒸馏清洗槽11、真空蒸馏回收槽13、冷凝储液槽15、废液回收槽17。
减压蒸馏清洗槽11的底部和真空蒸馏回收槽13的下部连通。
减压蒸馏清洗槽11的顶部连接有一个真空泵111，以抽取真空。
冷凝储液槽15安装固定在真空蒸馏回收槽13的上方，并与真空蒸馏回收槽13的顶部连通。
废液回收槽17安装固定在真空蒸馏回收槽13的下方，并与真空蒸馏回收槽13的底部连通。
减压蒸馏清洗槽11与冷凝储液槽15之间安装有抽液泵112，把冷凝储液槽15内的液体抽到减压蒸馏清洗槽11中。
减压蒸馏清洗槽11与真空蒸馏回收槽13之间安装有抽液泵114，把减压蒸馏清洗槽11内的液体抽到真空蒸馏回收槽13中。
超声波清洗机2包括有超声波清洗槽21和第一储液槽23。
超声波清洗槽21的底部和第一储液槽23的下部连通，它们之间安装有抽液泵212。
真空清洗干燥机3包括有蒸汽清洗干燥槽31、第二储液槽33。
蒸汽清洗干燥槽31的底部和第二储液槽33的下部连通，它们之间安装有抽液泵312。
蒸汽清洗干燥槽31的顶部连接有一个真空泵311，以抽取真空。
上述手机塑胶机壳镭雕后残渣的清洗方法，包括下列步骤：
步骤1：将醇醚类溶剂分别加入到减压蒸馏清洗槽11、冷凝储液槽15、超声波清洗槽21、第一储液槽23、蒸汽清洗干燥槽31和第二储液槽33内；
步骤2：将用清洗剂清洗掉镭雕后残渣的手机塑胶机壳放入篮具中；
步骤3：将装有手机塑胶机壳的篮具放入减压蒸馏清洗槽11内，然后在室温到90℃温度以下进行蒸汽清洗1-5分钟；
