一种铝电解槽废弃阴极在制备阴极碳块中的应用制造技术

本发明专利技术公开的铝电解槽废弃阴极在制备阴极碳块中的应用，涉及铝电解技术领域，是利用废阴极经浮选工艺分离出的碳粉，经过进一步的无害化处理后，作为再生料直接按比例掺入阴极原料中，伴随新阴极重新返回至电解槽中，实现废阴极在电解铝生产系统中的循环利用；一种再生料的添加是通过直接与新原料按比例混合，通过阴极碳块生产工艺制备出再生料均匀分布在整个阴极碳块中的阴极碳块；另一种再生料的添加是通过再生料与新原料配置成几种混合比例的原料，通过阴极碳块生产工艺制备出再生料含量从高到低呈梯度分布的阴极碳块；本发明专利技术在实现废弃阴极在电解铝生产系统中的循环利用的同时，解决了废弃阴极的资源浪费和环境污染的问题。

Application of aluminum electrolysis cell waste cathode in preparation of cathode carbon block

The present invention discloses aluminum electrolysis waste cathode preparation of cathode carbon block in the system, relates to the technical field of aluminum electrolysis, using waste cathode by flotation separation of toner, after further harmless treatment, as recycled materials in direct proportion with the incorporation of cathode materials, returned to the new cathode electrolysis the slot, using waste cathode in the electrolytic aluminum production system in a cycle; add renewable materials is through direct and new raw materials are mixed in proportion, the cathode carbon block production process preparation of cathode carbon block of recycled material is distributed uniformly in the cathode carbon blocks; another is to add renewable materials the recycled material and new material configured to several mixing ratio of raw materials, the production process of cathode carbon block prepared by recycled content from high to low gradient cathode carbon block; the invention can waste While recycling the cathode in the electrolytic aluminum production system, the waste of the cathode and the pollution of the environment are solved.
