Automatic classifying splitting method for waste lead acid battery recovery

Abstract

The invention relates to a waste lead-acid battery recovery automatic disassembly method, belonging to the field of environmental protection technique. The waste lead-acid battery recovery automatic disassembly method comprises the steps as follows: (1) the lead-acid battery is cut as an upper cover part ad a shell part; (2) the upper cover part is crushed and separated by winnowing so as to obtain upper cover plastic and a lead grid; and (3) after part of lead grid and lead mud of the shell part are swilled by turnover operation, the shell part is crushed, vibrated and screened so as to obtain the shell plastic above the screen and the lead grid and lead powder below the screen. The lead-acid battery recovery automatic disassembly method leads the disassembly process of lead-acid battery to be mechanized and automated, improves the recovery rate of the lead, leads different plastic products of the upper cover and the shell to be recovered by classification simultaneously, improves the recovery utilization ratio of the lead-acid battery, uses an alkali liquid circulation system and a dedusting system simultaneously, leads the whole process to have no drainage of waste water or waste liquid, and really realizes safe and environment-protective disassembly.

AI Technical Summary

Benefits of technology

This technology helps recover spent batteries by breaking them up into smaller pieces for easy disposal or reuse. It also makes it easier to separate various types of materials from each other without creating wastes like dirt and liquids during this process. Additionally, there's no harmful chemical residue left over after the breakdown with these systems being applied.

Problems solved by technology

This patented technical solution described for disposal purposes involves collecting discarded electrical storage devices like spent lead-aimers from various sources such as manufacturers' facilities where they were produced. These collections contain different types of material including lead, sourced acids, resin residue, etc., making it difficult if not properly managed without being categorized into specific categories. Additionally, certain parts may be reused but with potentially dangerous chemical substances added during production processes.
