Description

technical field [0001] The invention belongs to the field of aluminum electrolysis anode assembly, and in particular relates to an aluminum electrolysis anode steel claw spraying graphite system and a spraying method using the same. Background technique [0002] With the continuous development of the aluminum industry, graphite spraying on anode steel claws in aluminum electrolysis production has become an important operation for enterprises. Ring pressure removal efficiency, improve phosphorus pig iron recovery rate, reduce iron-carbon pressure drop between anode and steel claw, reduce comprehensive power consumption of aluminum electrolysis, specially designed and invented aluminum electrolysis anode steel claw automatic spraying graphite method and device. [0003] In the production of aluminum electrolysis, the anode steel claw and the carbon block need to be cast together with phosphorus pig iron. In order to prevent the steel claw and iron ring from sticking to the ste...

Problems solved by technology

[0004] At present, the aluminum electrolysis anode steel claw spraying graphite adopts manual brushing or graphite dipping process, that is, manually dipping graphite with a brush to paint on the anode steel claw or soaking the anode steel claw in diesel oil and then dipping in graphite powder , this method is not only labor-intensive and time-consuming, but also inefficient, and the uneven graphite coating makes it difficult to press off the phosphorus pig iron ring; in addition, the amount of diesel oil soaked in diesel oil is too large, which causes diesel oil to burn during casting and pollutes the environment and casts Cracks or bubbles occur in the phosphorus iron ring, and the anode iron-carbon pressure drop increases, which affects the overall power consumption of aluminum electrolysis.

[0005] At present, the method to solve this problem is mainly to use natural gas or electricity to heat and dry the steel claws soaked in diesel oil, but it is a waste of energy and has poor economic efficiency.
