Abstract

The invention discloses an upper structure of a large scale aluminium cell, which comprises a cross beam (1), a vent stack (2), a positive bar (3), an anode carbon block group (4), an anode winding gear (5), a crust breaking charging device (6). The anode carbon block group (4) uses the binode structure; wherein, the binode structure of the anode carbon block group (4) is that an aluminum guide bar is connected with two carbon blocks (8) by eight steel claws (7); every four steel claws (7) are distributed to each carbon block (8). The eight steel claws (7) and one anode rod are welded into one whole. The anode winding gear (5) uses an end single motor for concentrating driving. The cross beam (1) uses the plate web girder structure. The vent stack is arranged below the cross beam (1). The positive bar (3) uses the split type structure. The web plate of the cross beam (1) is provided with a hole (9) which a balance busbar passes through. The anode has 40-56 pieces and is configured by the busbar with 5-7 dot large area incoming electricity.

Description

technical field [0001] The invention relates to an upper structure of an electrolytic tank for electrolytic production of metal aluminum by molten liquid electrolysis. Background technique [0002] The upper structure of the large-scale aluminum electrolytic cell is composed of anode carbon block group, anode busbar, shelling and feeding device, anode lifting mechanism, girder, door-shaped column and tank airtight exhaust system, etc. The main structure is the web beam. The web beam is supported on the tank shell by four columns, and the column and the tank shell are hinged. The web beam is a steel plate welded component, and the cross-section is I-shaped steel. The total load composed of the shelling and feeding device and the busbar lifting frame. The shelling and feeding device, anode lifting mechanism, etc. are installed on the web beam. The airtight exhaust system of the groove is composed of the flue, the horizontal cover plate and the side cover plate. The flue is co...
