Abstract

The invention discloses a continuous-anode-based aluminum electrolysis device. The continuous-anode-based aluminum electrolysis device comprises an aluminum electrolysis cell, an anode structure, an electricity feeding device and a shell crushing and discharging mechanism, the anode structure is arranged above the aluminum electrolysis cell, and the shell crushing and discharging mechanism is arranged on the outer side of the anode structure. The continuous-anode-based aluminum electrolysis device is characterized in that the anode structure includes an anode frame and an anode, and the outerside wall of the anode frame is connected with a vertical wing plate; the electricity feeding device comprises a clamping mechanism and a conductive block, the clamping mechanism comprises two clamping jaws and a cylinder used for driving the two clamping jaws to open and close oppositely; the conductive block is fixed to the inner side of one of the clamping jaws, the conductive block is connected with the positive bar of the anode through flexible connection; and the clamping mechanism is used for clamping an anode frame wing plate. According to the continuous-anode-based aluminum electrolysis device, the problem of voltage fluctuations caused by a traditional electricity feeding mode is solved, and smoke at a discharging point can be collected to prevent the smoke leakage.

Description

technical field [0001] The invention belongs to the technical field of aluminum electrolysis, and in particular relates to an aluminum electrolysis device and method based on continuous anodes. Background technique [0002] Self-baking tank aluminum electrolysis, as a continuous anode aluminum electrolysis technology that appeared in the development of aluminum electrolysis technology, has made great contributions to the development of electrolytic aluminum industry. There are major defects in self-baked anode aluminum electrolytic cells: high electrolysis energy consumption and large material consumption; large asphalt fumes during electrolysis, which cannot be collected and processed centrally, resulting in poor plant environment; anode rods are complicated to pull out and require sand washing procedures Lead to low degree of mechanization and high labor intensity. These inherent defects cannot be completely solved, leading to the gradual replacement of self-baked anodes ...
