Continuous anode device for intelligent electrolytic baths and application method thereof

Abstract

The invention relates to a continuous anode device for intelligent electrolytic baths and an application method thereof, belonging to the field of metallurgy. The continuous anode device for intelligent electrolytic baths comprises a continuous anode carbon block, an anode carbon block positioning push system, a continuous anode carbon block crawler-type displacement system, a slide power supply system and an intelligent control system. The application method comprises the following steps: (1) a continuous anode carbon block is installed; (2) the continuous anode carbon block is fixed to the continuous anode carbon block crawler-type displacement system to implement continuous movement; (3) when the crawler operates, the working anode carbon block is driven to move downwards, and the anode carbon block positioning push system can push a standby anode carbon block to the fixed position so as to be connected with the original carbon block; and (4) when the continuous anode carbon block moves downwards, the slide power supply system correspondingly moves upwards so as to implement the connection between the anode carbon block and the anode. The device implements the continuity of the aluminum electrolytic bath anodes, solves the problem of discontinuous anode replacement and stub generation at present, and lowers the cost of the aluminum electrolysis process.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a continuous anode device for an intelligent electrolyzer and a method for using the same. Background technique [0002] Prebaked anode aluminum electrolytic cells have become the technical mainstream of aluminum smelting methods in the world today. However, the production of traditional aluminum electrolytic cells adopts the process of "discontinuously replacing prebaked anodes", which has the following problems: ① The investment and operating costs of the supporting anode assembly production line increase; about 20%); ③The anode residue is returned to the anode production system as an additive, which greatly reduces the quality of the prebaked anode. [0003] Taking the 300,000-ton aluminum electrolysis series project as an example, the infrastructure investment of the supporting anode assembly production line is about 103 million yuan, which is equivalent to an increase of about 264...

AI Technical Summary

Problems solved by technology

However, the production of traditional aluminum electrolytic cells adopts the process of "discontinuously replacing prebaked anodes", which has the following problems: ① The investment and operating costs of the supporting anode assembly production line increase; about 20%); ③The residual anode is returned to the anode production system as an additive, which greatly reduces the quality of the prebaked anode

The disadvantages of this structure are: the mid-point automatic feeding technology cannot be used, the size of the prebaked anode is too large and it is difficult to replace, and the quality requirements for the special bonding paste are very high, etc.

The patent "Continuous Prebaked Anode Combination Structure of Aluminum Electrolyzer (CN103088367A)" provides a new type of fixture used in conjunction with special-shaped anode carbon blocks, which can solve the problem of residual electrodes, but the anode cannot be replaced continuously

The patent "a continuous anode device for aluminum electrolytic cell (CN2552947Y)" proposes to use crawlers and anode paste to realize continuous anode supply. This patent uses anode carbon blocks similar to self-baked anodes, and does not provide a connection method for anode busbars
