Recycling of used lead-acid batteries can not only effectively utilize resources, but also reduce environmental pollution. The following is a detailed description of the main steps of dismantling and recycling used lead-acid batteries and their related equipment and processes.

Battery dismantling is the first step in the recycling process. Using a specialized battery dismantling machine, the battery is disassembled into components such as the battery shell cover, wastewater, battery case, and electrode plates. Subsequently, the battery case cover can be broken into pellets using a crusher, and the plastic pellets and lead and copper pellets can be separated by water flotation. The lead particles can be heated and melted into a lead solution, while the copper particles can be separated by filtration.

Lead Acid Battery Recycling System

Wastewater treatment is a non-negligible part of the recycling process. Wastewater can be neutralized by acid and alkali treatment first, and then enter the general sewage treatment system for further treatment. Battery shells can be cleaned and then crushed into granules for reuse.

Electrode plate treatment requires the use of a crusher to break the electrode plate into particles, and then a roller to separate the lead sludge attached to the electrode plate. The electrode plates can be directly smelted into alloy ingots, while the lead sludge requires further treatment. The treatment of lead sludge includes reacting with alkali to separate soluble sulfate and insoluble lead-containing particles; reacting insoluble lead particles with inorganic acid to generate lead inorganic acid salt solution, and then reacting with soluble carbonate to precipitate lead; finally, the precipitated lead particles are roasted at 350°C to generate lead oxide.

The dismantled lead blocks can be smelted into lead ingots with a purity of 97% or more through a smelting furnace. The plastic shells can be reused by crushing them into pellets through a crusher.

In terms of equipment, the dismantling machine is used to dismantle the battery, cut the battery cover, and separate the various parts. The crusher is used to crush the battery shell cover, electrode plate, and plastic shell for subsequent processing. A water flotation device is used to separate plastic particles and metal particles (lead, copper). A drum separator is used to separate the lead sludge from the electrode plates. The smelting furnace is used to smelt the lead lumps to make high-purity lead ingots.

The recycling of used lead-acid batteries requires a series of equipment and processes that can realize the efficient recycling and reuse of all battery components and reduce environmental pollution. Through automated and intelligent dismantling equipment, the recycling efficiency of used lead-acid batteries is greatly improved, and the resource utilization rate is significantly increased, which helps to promote the sustainable use of resources and the development of environmental protection.
