Background technique

With the rapid development of the automobile industry and the electronics industry, batteries have become an important part of the products in this industry. While batteries bring convenience to people's work and life, they also bring hidden dangers of pollution. Waste batteries after use contain A large amount of heavy metals and electrolytes, whether the used batteries are buried deep or stacked with bare drains, heavy metals and electrolytes will overflow, causing groundwater and soil pollution, which will seriously endanger human health. Lead storage battery is currently the most widely produced and used battery in the world, and its sales account for more than 30% of global battery sales. At present, from the perspective of the overall domestic level, the production scale of recycled lead is small, the energy consumption is high, and the industrial technology is backward. The relatively backward technology is used to recycle lead batteries, and the waste batteries are dissected manually or by simple mechanical devices. The electrolyte is dumped everywhere, and the plastic Solid waste such as casings and partitions are piled up on the spot. After the lead grid is taken out and separated from the partition, the lead paste and the lead grid are not separated and are directly melted in the reverberatory furnace. and low utilization.

The utility model has the advantages of:

1. Fully clean and separate the crushed lead-acid battery mixture, so that the lead grid, lead paste, polypropylene shell and separator can be reused as raw materials to save resources;

2. No pollution to the environment and good environmental benefits;

3. In this device, the structure of each separation device is compact and reasonable, which saves the use of space and realizes intensive production;

4. This device makes full use of the advantages of domestic equipment and adopts the combination of domestic equipment and imported equipment, which not only meets the requirements of the system, but also saves money;
