随着锌电积过程的进行,不断有以含二氧化锰为主的阳极泥产生并沉积于槽底,当阳极泥累积增加后,不但影响电解液的循环,而且会使阴阳极发生短路,造成电流效率下降和析出锌含铅增高,因此必须及时清除。清理周期一般为1～2个月。清理方式多种多样。我厂过去一直采用砂泵抽送,然后进行人工清理,操作条件差,劳动强度大,浪费也大。1973年进行了蒸汽喷射泵真空掏槽的试验,取 With the progress of zinc electrowinning process, anode slimes mainly containing manganese dioxide are continuously produced and deposited on the bottom of the trough. When the anode slime accumulates, it not only affects the circulation of the electrolyte but also shorts the anode and cathode, Resulting in decreased current efficiency and precipitation of lead and lead, it must be promptly removed. Cleaning cycle is generally 1 to 2 months. There are many ways to clean up. In the past, our factory has been pumping with sand pumps, and then manually clean up, poor operating conditions, labor-intensive, waste is also large. In 1973 the steam jet pump vacuum cut test, take
