Description

Battery pack recycling workstation

Technical Field

The utility model relates to a battery recovery processing technology field specifically is a battery package recovery processing workstation.

Background

When the capacity of the power battery is attenuated to be below 80% of the rated capacity, the power battery is scrapped and recycled, and the recycled battery pack is firstly disassembled and separated.

The existing scrapped battery pack is low in recovery rate due to the fact that harmful gases (including HF, Cl2, CO2 and CO) are generated when metal is directly recovered through high-temperature heat treatment, and bubbles are easily contained after the metal is dissolved;

the existing disassembling technology mainly comprises the following steps: 1. mechanical and wet processes; 2. ordinary high-temperature recovery, two technologies, but mechanical and wet processes can use a large amount of water to cause water pollution, the ordinary high-temperature recovery can be contaminated by a large amount of bubbles in the metal melting process to be not beneficial to metal recovery, and meanwhile, a large amount of harmful gas can be generated in the high-temperature process;

in the battery package high temperature recovery process, the smelting furnace is direct heats the battery package to about 1200 ℃, plastics in the battery, adhesive will produce a large amount of harmful gas in this in-process, and this harmful gas directly discharges, makes serious harm to the environment, and some residual gas can persist in the metal body of high temperature liquefaction with the bubble form, and residual bubble in the metal body influences the metal recovery rate, is unfavorable for later stage processing to select separately, is difficult to satisfy the demand of current battery package recovery processing workstation.
