Description

Technical Field

[0002] Storage batteries (also known as secondary batteries or lead-acid batteries) are widely used energy storage devices in modern society. Their core function is to realize the recycling of electrical energy through reversible chemical reactions. A storage battery is an electrochemical device that converts chemical energy into electrical energy and can be repeatedly charged. It is mainly used to store and release electrical energy. Through the chemical reaction of internal active materials (such as lead and its oxides, sulfuric acid electrolyte, etc.), the stored chemical energy is converted into electrical energy output; during charging, the reverse reaction is carried out to store the electrical energy back into chemical energy.

[0003] The multi-stage screening device, through multi-stage crushing and screening processes, can thoroughly crush and screen waste batteries, separating them into materials of different particle sizes, which is beneficial for subsequent utilization. This fine processing can significantly improve the metal recovery rate and purity; for example, the purity of copper-aluminum foil separation can reach 99.2%, and the recovery rate of positive and negative electrode powder exceeds 98%. During the screening process, the multi-stage screening device is equipped with environmental protection equipment, such as cyclone separators, pulse dust collectors, and spray towers, which can effectively prevent material spillage and loss and pollution to the surrounding environment, meeting environmental protection requirements. This design not only reduces wastewater discharge and energy consumption but also reduces negative environmental impacts.
