Description

Technical Field

[0002] Lithium batteries are widely used in the automotive, digital, and photovoltaic industries, generating enormous market demand. The copper, aluminum, iron, and positive and negative electrode powders contained in used lithium batteries all have significant recycling value. With the increasing number of discarded batteries, battery recycling and reuse are crucial from both an environmental and sustainable development perspective. Battery recycling begins by placing the batteries in a pyrolysis carbonization furnace, where they undergo high-temperature pyrolysis, converting the electrolyte into flue gas and pyrolyzing and carbonizing organic materials such as the separator and binder within the battery. The pyrolyzed batteries are then crushed, and a series of screening steps are performed to separate the copper, aluminum, iron, and positive and negative electrode powders from the crushed batteries.

[0003] When batteries are pyrolyzed in a carbonization furnace, most of the time the batteries are placed in the carbonization furnace and pyrolyzed by the high temperature inside the carbonization furnace. However, this method generally stacks the batteries together in the carbonization furnace, which causes uneven heating of the batteries during pyrolysis. The pyrolysis time is long, resulting in low pyrolysis efficiency and inconvenience in loading and unloading of used batteries. Utility Model Content

After the pyrolysis of the waste batteries in the pyrolysis chamber 2 is completed, the walking assembly 3 drives the pyrolysis chamber 2 to move outside the heating space 11. The high-temperature hot air around the pyrolysis chamber 2 will dissipate to the surroundings. Therefore, in order to prevent the high-temperature hot air from burning the staff, two fire-blocking components 5 are set on the support plate 32, so that they and the insulation plate 31 form a fire-blocking fence set around the pyrolysis chamber 2, thereby allowing the high-temperature hot air around the pyrolysis chamber 2 to dissipate upward, thereby protecting the staff; since the fire-blocking component 5 has the freedom to rotate along the support plate 32, when loading and unloading waste batteries, the fire-blocking fence can be opened by rotating the fire-blocking component 5, thereby facilitating the loading and unloading of waste batteries by the staff.
