Anode oxidation preventing device for prebaked anode electrolyzer

The utility model discloses a anode oxidation preventing device for a prebaked anode electrolyzer, which comprises an anode carbon block (1) and a side edge (2) of the electrolyzer, wherein an anode baffle plate (3) is arranged between the anode carbon block (1) and the side edge (2) of the electrolyzer, the anode baffle plate (3) is placed on a housing (4) formed by aluminum electrolyte solution, and a thermal insulation material (5) is arranged between the anode baffle plate (3) and the anode carbon block (1). As the side part of the anode carbon block is blocked by the anode baffle plate, the material can not be scattered to a radiating ribbon on the side edge of the electrolyzer when blanking the thermal insulation material and shaping, and a slope does not need to be piled up for retracting the radiating ribbon, thereby reducing the workload and the working time of the traditional anode exchange operation, reducing the process steps and reducing the labor intensity of working. In addition, the width of t
