1. structurally, the aluminum electrolyzing cell used specially-shaped cathode rod iron of the utility model is by being designed to non-rectangular configuration by the cross section of cathode steel bar body, or cross section is rectangular configuration, its entirety is variable cross-section change structure along its length, thus increase the contact surface of rod iron and charcoal block, suffered by dispersion rod iron self, the effect of electrolyte bath stress, reduces the thermal shocking that local is born, and reduces the amplitude of thermal expansion; Reduce the generation of negative electrode crackle, electrolyzer early damage and bakie risk, the long-term stability contributing to electrolyzer is run and improves cell life; And can effectively improve distribution of current, stablize metal wave.
2., structurally, when the cross section of cathode steel bar body described in the utility model is bow-shaped structural, its entirety is uniform cross section change structure or variable cross-section change structure along its length; Wherein, described variable cross-section change structure is continuous deformation changes of section structure or stepped appearance variable cross-section change structure; Embodiment is more, and structure formation is versatile and flexible, is easy to promotion and implementation.
3., when the utility model uses, according to practical situation flexible Application, different customer needs can be met.Can design according to concrete electrolyzer grooved, concrete size is determined according to production actual needs; And according to the novel rod iron of design, cathode carbon pieces dovetail-indent makes the appropriate adjustments; Wherein, cathode assembling adopts phosphorus pig iron casting craft or artificial mode admittedly of pricking to assemble; Thus, easy for operation.
4, to sum up, the utility model aluminum electrolyzing cell used specially-shaped cathode rod iron structure is simple, easy for operation, can effectively dispersion slot internal stress, adjust distribution of current, slow down metal wave, and reduce breakage risk, ensure electrolyzer safe and stable operation, and, embodiment is more, structure formation is versatile and flexible, therefore, is very suitable for promotion and implementation.
