铝电解多功能机组变幅四连杆打壳机构设计改进

铝电解多功能机组是大型铝电解生产的机械化专业操作设备,打壳机构是铝电解多功能机组中的主要工具之一,结构非常复杂。本文通过对旧式连杆打壳机构在实际应用中产生问题的分析及缺陷的设计改进,重点介绍了一种结构相对简单、工作效率高、可将电解槽中缝的氧化铝结壳打碎的新型变幅四连杆打壳结构,经过实践运用,效果良好,是一种极具推广价值的新型结构。

Design improvement of four bar mechanism for crust breaker unit on PTM

PTM is special designed machine for Large scale Aluminium smelt plant, Crust breaker is one of tools mechanism plays important role among others with rather complicated structures, this paper analyse the fault of troditional style crust breakers met during practical uses, consequently ,bring up the idea of improvement in designation. The new designed crust breaker featured with four bar mechanism has simpler slucture, higher efficency compare to the old ones, and more, it can even break off the alumina crust clamped in gaps of electrolytic cell. By many times of testing, it is approved to be reliable and effictive.
