Description

一种物理法回收电解板残极的方法 技术领域
本发明是涉及一种物理法回收电解板残极的方法，属于电解技术领域。
背景技术
由于电解冶金具有高选择性，可获得高纯金属，能回收有用金属，且对环境的污染较小，生产也较易实现连续化和自动化，因此通常用于金属提取和提纯工艺中。因电解阳极板在电解消耗到一定厚度时，必须停止电解，若继续电解就会产生残极断板，掉落到电解槽中，造成安全事故，这种电解剩下的阳极板就是本申请中所称的电解板残极。现有技术中，对电解产生的电解板残极通常是采取回炉重新熔铸成电解板，而这种熔铸法会导致环保污染和能源消耗问题，不能满足工业化生产要求。为了解决熔铸法回收电解板残极所存在的上述问题，本申请人在专利号为201410741725.6的中国发明专利中提出了一种可降低阳极电解残存率的阳极板，所述阳极板包括挂钩、金属板和连接网，所述金属板是由连接网及熔铸在连接网表面的被电解金属形成。虽然该专利通过使被电解的金属熔铸在连接网上，通过连接网的骨架作用，可有效防止金属板发生断裂和脱落到电解槽中，从而可提高金属电解的利用率，降低阳极电解残存率，但采用该专利技术仍然存在电解板残极，对于产生的电解板残极，专利号为201410741725.6的中国发明专利仍然需要回炉重新熔铸成电解板进行回收利用，因而此专利还不能理想满足工业化生产需求。
发明内容
针对现有技术存在的上述问题，本发明的目的是提供一种物理法回收电解板残极的方法，以实现能源环保回收电解板残极，使满足金属电解行业的工业化生产需求。
为实现上述发明目的，本发明采用的技术方案如下：
一种物理法回收电解板残极的方法，包括压力机和压模，所述压模包括与电解板形状相适配的型腔及横截面形状与所述电解板的纵截面或横截面相同的模头，所述方法包括将电解板残极放入到型腔里，然后通过压力机将模头压入到型腔里，通过模头的挤压作用将电解板残极压制成电解板形状。
本发明通过采用直接压制的物理方法实现电解板残极的回收，可有效避免熔铸法产生 的污染问题，具有环保优点；另外，本发明采用从纵截面或横截面方向进行挤压，可大幅度降低压制成本和压力机的要求，具体说：以压制规格为1米×1米×0.04米的铜电解板为例，若采用现有的正面挤压方法，需要二万三千吨的压力机才能使铜电解板的比重达到8.0吨/立方米(低于该比重会产生断板安全事故)，而这种大型万吨压力机全国不到十台，并且价值非常昂贵，价格上亿元，并且这种大型设备的操作费用也非常高，每吨的直接生产成本高达千元以上，比熔铸成本(需要八百元左右)还要高；由于该规格的铜电解板的纵截面或横截面的面积均为0.04平方米，而正面的面积是1平方米，即：正面面积是纵截面或横截面面积的25倍，因此在达到同样压强下，所需要的压力可由原来的二万三千吨降到920吨，而一台1000吨压力的压力机价格只有九万元左右，生产的操作费用也只要60元/吨，远远低于现有熔铸成本和正面压制的成本，因此，具有巨大的经济效益和社会效益。
一种优选方案，将所述电解板残极先进行粉碎，然后再放入型腔进行挤压。由于实际产生的电解板残极的厚度和重量都不一致，为了保证压制成型的阳极板的重量一致性和实现自动化加料，采取先粉碎再进行压制成型，既可提高生产效率，又可保证压制的每块电解板的重量一致。
一种优选方案，对电解板残极或经粉碎后的电解板残极先进行加热处理，使其在加热处理后再进行挤压。如果直接进行挤压成型，特别是需要压制成大尺寸电解板时，将对压力机的压力要求高，如果压力不够会使挤压成型的电解板在电解过程中产生破裂，导致断板安全事故。通过加热处理，可以极大地提高电解板的机械强度，既可降低对压力机的压力要求，也可避免在电解过程中的断板现象。
一种优选方案，所述型腔的上端或下端呈导电钩形状，通过此种型腔的设计，可直接压制得到具有导电钩的电解板以直接用于电解，从而大大简化生产流程，提高生产效率。
进一步优选方案，在构成导电钩的型腔中先设置一根与所述电解板同质的金属棒或管。由于电解板上的导电钩在电解过程中起悬挂和承重作用，因此，在构成导电钩的型腔中先设置一根与所述电解板同质的金属棒或管后，在挤压成导电钩时，金属棒或管会被埋在成型的导电钩中起到骨架作用，从而可防止导电钩在运输和电解过程中发生断裂。
一种优选方案，在所述型腔的上端或下端先设置一根导电钩。由于导电钩是不参与电解的，只起导电作用，所以如果可实现导电钩的反复使用，也可节省回收成本。
进一步优选方案，所述导电钩上设有榫头或卯眼，所述导电钩与金属板之间采用榫卯结构连接。榫卯结构连接方便，无需采用螺栓相连，不仅减少了生产工序，而且金属板连 接部分与其余部分保持同样的电解面积，使电解残存率得到显著降低。当然，所述榫卯结构采用锥形榫卯结构，不仅连接方便，容易安装，可以提高生产效率，而且可以增大导电钩与金属板的接触面积，减少电阻，降低槽电压，节省电能。
进一步优选方案，所述榫头或卯眼由钛、钛合金、镀铜的钛或镀铜的钛合金制成，导电钩的连接部分是采用钛或钛合金材料。因为导电钩的连接部分是浸泡在电解液里，如果采用其它金属材料会被电解成金属离子进入电解液中，但钛或钛合金本身在电解液里是惰性材料，不参与电解。所述导电钩的连接部分是采用镀钛或钛合金材料，或者采用镶钛或钛合金。如果导电钩全部采用钛或钛合金虽然可以保证在电解过程中不会进入电解液中，但钛的导电性比较差，会增加电阻，从而增大了电解槽的槽电压，槽电压增大会增加电能的损耗。如果采用电镀镶钛或钛合金，只是浸入电解液的部分电镀钛或钛合金、或者镶钛或钛合金，由于镀或镶的部分非常薄，电阻非常小，对槽电压的影响不大。所述导电钩以铜表面镀/镶钛或钛合金为最佳，因为铜的导电性在普通金属里是最好的，用铜作导电钩效果最好(银除外，银是贵金属)，也最实用，当在铜表面镀/镶钛或钛合金时，可避免铜发生电解，既可保留铜的良好导电性，又可减小电解电阻。
一种优选方案，先用小压力机进行预压，然后再用大压力机进行挤压。先用小型压力机进行预压制，当达到一定压力后，再换用大型压力机进行挤压成型，可以大幅度降低设备使用成本，增加经济效益。
与现有技术相比，本发明具有如下显著性有益效果：
1)环保：本发明通过采用直接压制的物理方法实现电解板残极的回收，可有效避免熔铸法产生的污染问题，具有环保优点；
2)可显著降低对电解板残极的回收成本：对于压制相同尺寸规格的电解板，本发明采用从纵截面或横截面方向进行挤压的成本相对于现有的正面挤压成本，可得到显著降低，大约可降低80％；
3)对设备要求低：对于压制相同尺寸规格的电解板，本发明所需压力机的压力可明显降低，对设备要求低，从而使设备成本可得到明显降低；
4)易于实现工业化，对金属电解行业的工业化生产具有显著的经济价值。

图2是本发明实施例2压制得到的电解板的结构示意图。
图3是本发明实施例3压制得到的电解板的结构示意图。
图中标记示意如下：1、金属粉；2、型腔；3、入料口；4、模头；5、电解板；51、金属板；52、导电钩；521、卯眼；53、金属棒或管。
具体实施方式
下面结合实施例和附图对本发明技术方案做进一步详细、完整地说明。
实施例1
参照图1所示，本实施例提供的一种物理法回收电解板残极的方法是：将经清洗掉电解质后的电解板残极(例如：电解铜阳极板残极)粉碎成金属粉1，然后通过型腔2的入料口3加入到模型腔2内，再通过压力机(图中位示出)的作用使模头4将金属粉1进行挤压，直至挤压成电解板。所述型腔2与电解板形状相适配，所述模头4的横截面形状与所述电解板的纵截面或横截面相同。
以压制规格为1米×1米×0.04米的铜电解板为例，若采用现有的正面挤压方法，需要二万三千吨的压力机才能使铜电解板的比重达到8.0吨/立方米(低于该比重会产生断板安全事故)，而这种大型万吨压力机全国不到十台，并且价值非常昂贵，价格上亿元，并且这种大型设备的操作费用也非常高，每吨的直接生产成本高达千元以上，比熔铸成本(需要八百元左右)还要高；由于该规格的铜电解板的纵截面或横截面的面积均为0.04平方米，而正面的面积是1平方米，即：正面面积是纵截面或横截面面积的25倍，因此在达到同样压强下，所需要的压力可由原来的二万三千吨降到920吨，而一台1000吨压力的压力机价格只有九万元左右，生产的操作费用也只要60元/吨，远远低于现有熔铸成本和正面压制的成本，因此，采用本发明方法，可实现巨大的经济效益和社会效益。另外，本发明通过采用直接压制的物理方法实现电解板残极的回收，还可有效避免熔铸法产生的污染问题，具有环保优点。
实施例2
请参见图2所示：由于电解板5是由金属板51和导电钩52组成，因此，当使型腔2的上端或下端呈导电钩52形状，可直接压制得到具有导电钩52的电解板5以直接用于电解，从而可大大简化生产流程，提高生产效率。
另外，由于电解板5上的导电钩52在电解过程中起悬挂和承重作用，因此，在构成导 电钩的型腔中先设置一根与所述电解板5同质的金属棒或管53后，在挤压成导电钩52时，金属棒或管53会被埋在成型的导电钩52中起到骨架作用，从而可防止导电钩52在运输和电解过程中发生断裂，增加导电钩52的机械强度。
实施例3
由于导电钩是不参与电解的，只起导电作用，因此实现导电钩52的反复使用，也可节省回收成本，因此，本实施例通过在型腔2的上端或下端先设置一根导电钩52，在所述导电钩52上设置榫头或卯眼(本实施例中以卯眼521为例)，使所述导电钩52与金属板51之间采用榫卯结构连接(请参阅图3所示)。电解结束后，金属板51残极与导电钩52之间很容易脱离开，从而可实现导电钩的重复使用，降低生产成本。
作为优选方案，所述导电钩的连接部分采用钛或钛合金材料。因为导电钩的连接部分是浸泡在电解液里，如果采用其它金属材料会被电解成金属离子进入电解液中，但钛或钛合金本身在电解液里是惰性材料，不参与电解。如果导电钩全部采用钛或钛合金虽然可以保证在电解过程中不会进入电解液中，但钛的导电性比较差，会增加电阻，从而增大了电解槽的槽电压，槽电压增大会增加电能的损耗，因此所述导电钩的连接部分以采用镀钛或钛合金材料，或者采用镶钛或钛合金为较佳。由于铜的导电性在普通金属里是最好的，因此用铜作导电钩效果最好(银除外，银是贵金属)，也最实用，因此采用铜表面镀/镶钛或钛合金制作导电钩为最佳方案，这样既可保留铜的良好导电性，又可减小电解电阻。
最后需要在此指出的是：以上仅是本发明的部分优选应用例，不能理解为对本发明保护范围的限制，本领域的技术人员根据本发明的上述内容做出的一些非本质的改进和调整均属于本发明的保护范围。
