Description

Technical Field

[0001] This utility model relates to the field of anode carbon block mixing technology, specifically to a prebaked anode carbon block mixing device for electrolytic aluminum. Background Technology

[0002] Prebaked anodes are electrode products made from petroleum coke and pitch coke as aggregates and coal tar pitch as a binder. They are used as anode materials in prebaked aluminum electrolytic cells. Prebaked anodes have developed alongside the aluminum industry. In the electrolytic aluminum production process, prebaked anodes are both immersed in the electrolyte of the electrolytic cell as anodes and participate in electrochemical reactions, thus being consumed. Therefore, they are an indispensable material in the production of electrolytic aluminum and are widely used in many fields such as aviation, aerospace, automotive, and construction.

[0003] In the production process of prebaked anode carbon blocks, it is necessary to mix the calcined coke granule carbon anode mixture with binders such as coal tar pitch or phenolic resin. For example, Chinese utility model patent No. 202320473983.5 provides a mixing device for prebaked anode carbon blocks for electrolytic aluminum. The calcined coke granule carbon anode mixture particles can be put into the crushing chamber through the feed pipe 2. The calcined coke granule carbon anode mixture particles are crushed into powder by the crushing component and then discharged into the mixing chamber through the connecting pipe. This reduces the unit amount of phenolic resin binder used. The binder in the tank is mixed with the calcined coke granule carbon anode mixture powder by stirring.

[0004] However, due to the high viscosity of the carbon anode mixture, existing mixing devices cannot shear the viscous raw materials during the mixing process, resulting in insufficient mixing of the binder with the petroleum coke and a decrease in the mixing effect. Therefore, in view of this, a prebaked anode carbon block mixing device for electrolytic aluminum is proposed to solve the above-mentioned technical problems. Utility Model Content
