The invention relates to the field of detection technology for short circuit of electrolytic plate, which is a cathode conductive rod used for detecting short circuit of electrolytic plate. The cathode conductive rod is coated with temperature-sensitive ink, and when the temperature-sensitive ink is dry, a transparent fiberglass reinforced plastics resin is brushed on its surface. The temperature-sensitive ink is yellow at low temperature, and when the temperature rises to a set value (60-65 degrees C), the pigment changes from yellow to white, and when the temperature rises to a set value (60-65 degrees C As the temperature continues to rise, the temperature-sensitive ink is still white, and when the temperature drops below 60 C, the temperature-sensitive ink will return to yellow; the invention has high visibility, convenient and fast operation, reduces the labor intensity of workers, better solves the problems of large workload and low efficiency of short circuit detection of electrolytic board, and greatly improves the work efficiency.

一种用于检测电解板短路的阴极导电棒
本专利技术涉及电解极板短路的检测
,具体是一种用于检测电解板短路的阴极导电棒。
技术介绍
在永久不锈钢法铜电解精炼中,含有杂质的粗铜阳极板作为阳极,不锈钢板作为阴极,阴阳极交错放置在盛装电解液的槽里进行通电生产。电解液是主要含Cu2+42~48g/L,H2SO4175~185g/L的水溶液。在生产过程中作为阳极的铜阳极板溶解,铜和部分杂质溶解进入电解液中,作为阴极的不锈钢板表面电解液中的Cu2+发生电化反应以纯铜形式析出。电极板是悬挂在电解槽内,阴阳极间的间距一般只有50mm,并且电解槽内的电解液是呈流动状态,阴极因局部电流集中析出增快,生长出凸瘤,致使阴阳极接触,发生阴阳极极板短路。阳极到了电解末期重心偏移,底部有可能接触到阴极,发生短路。短路不及时处理,阴极就会溶解,浪费电能,并且短路产生大量热量,导电棒表面温度升高,容易引起火灾。正常生产时阴极导电棒的温度低于60℃,当发生短路时温度都会超过。现有的短路查处是每隔三小时,往阴极导电棒洒水,通过观察水干的速度,判断极板的是否短路。电解铜的生产过程需要专人在电解槽的流水线 ...
