Waste lithium batteries contain a variety of valuable metal elements such as copper, nickel, and aluminum. If they are discarded at will, it will cause serious waste of resources and cause pollution to the environment. It is composed of carbon material negative electrode, diaphragm organic matter, electrolyte, positive and negative electrode current collector, explosion-proof disc, sealing ring, top cover, shell, etc. It is sustainable to recover and process waste lithium batteries, extract the metals in them, and recycle them. Direction of development. Lithium battery recycling and processing equipment Environmentally friendly waste lithium battery treatment method, positive and negative electrode materials and steel and separator can be recycled separately, making full use of valuable metal elements in lithium batteries, the overall structure of lithium ion batteries is compact, especially the positive and negative electrode active materials It is also bonded to the electrode sheet by an adhesive, and the powder is attached to the metal electrode sheet of the positive and negative electrodes, and is separated by a mechanical and physical method. Lithium battery recycling equipment is an environmentally friendly waste lithium battery treatment method.
1. Crushing and crushing waste lithium batteries to obtain primary debris materials; in the process of crushing and crushing, the electrolyte adsorption and collection device is used to remove the electrolyte;
2. Cut and crush the primary debris material to obtain secondary debris material; in the process of cutting and crushing, use the electrolyte adsorption and collection device to remove the electrolyte;
3. The secondary debris material enters the plastic material separation and collection device to realize the separation of the plastic material from the electrode material and current collector;
4. The secondary debris material after separating and removing the plastic material is sent to the hammer mill for deep crushing to obtain the tertiary debris material;
5. The tertiary debris material enters the battery material separation device for primary separation and collection, and the positive and negative electrode materials and the current collector particle mixture are obtained respectively;
6. The positive and negative electrode materials enter the cyclone for secondary separation and collection to obtain the negative electrode material graphite and the positive electrode material; the current collector particle mixture enters the vibrating screen for further separation to obtain copper and aluminum particles.
Lithium battery recycling and processing equipment uses physical methods to separate and collect various components in waste lithium batteries, and uses simple dry methods such as mechanical crushing, vacuum separation, vibration screening, specific gravity separation, and airflow separation to realize waste lithium batteries. Separation and collection of electrode materials, current collector metals, plastic separators, battery casings.
