Pretreatment structure and method for electrolytic aluminum waste residues

The invention discloses a pretreatment structure and method for electrolytic aluminum waste residues, the pretreatment structure comprises a smashing box and a collecting basin arranged below the smashing box, and a feeding hopper is formed in the top of the smashing box. According to the pretreatment structure and method for the electrolytic aluminum waste residues, after the electrolytic aluminum waste residues are smashed through the smashing assembly, under the arrangement of the splayed filter screen, the smashed waste residues meeting the size requirement are discharged into the collecting basin, and the waste residues not meeting the size requirement are guided into the storage box; through the arrangement of the driving assembly, the material conveying assembly and the arc-shaped guide plate, waste residues which do not meet the size requirement are conveyed to the smashing assembly to be smashed again, it is guaranteed that the waste residues collected and smashed in the collecting basin meet the siz
