Embodiment Construction
[0032] Below in conjunction with accompanying drawing and embodiment, content of the present invention is further described and supplemented:
[0033] The upper structure of the electrolytic cell of the present invention is composed of anode carbon block group 9, anode bus bar 5, shelling and feeding device 8, anode hoist 7, column 4, girder and tank airtight exhaust system 10 and 12, etc.
[0034] As shown in Figures 1 and 2, the following uses a 300KA electrolytic cell as an example for detailed description. In fact, this design scheme can also be applied to large-scale aluminum electrolytic prebaked cells of 280KA to 330KA.
[0035] 1. The upper structure of the electrolytic cell:
[0036] 1) Anode carbon block group 9
[0037] The anode carbon block group consists of aluminum conductive rods, steel claws and anode carbon blocks. The double anode form is adopted, which is characterized in that two anode carbon blocks are assembled together by an aluminum guide rod and ste...
