Description

Technical Field

[0001] This utility model relates to the field of lithium battery recycling, and more specifically, to a lithium battery recycling volatilization furnace. Background Technology

[0002] Lithium-ion battery recycling is a crucial environmental initiative aimed at reducing resource waste, preventing environmental pollution, and promoting the development of a circular economy. With the rapid growth of markets for electric vehicles, portable electronic devices, and other electronic devices, the number of used lithium-ion batteries has increased dramatically. Improper handling can lead to serious environmental damage from heavy metals and hazardous substances contained within them.

[0003] The prior art disclosed in patent publication (announcement) number CN220552276U is a lithium battery recycling volatilization furnace, including a furnace body and a heating jacket. The furnace body is provided with a feed hole, a discharge hole, and a gas outlet. The heating jacket is fitted onto the furnace body. An annular steam chamber surrounding the furnace body is formed inside the heating jacket. Multiple annular partitions are spaced apart along the axial direction of the heating jacket in the annular steam chamber. The multiple annular partitions divide the annular steam chamber into multiple annular channels. One of the two outermost annular channels is provided with a steam inlet and the other with a steam outlet. A sealing plate is provided inside the annular channel. The sealing plate divides the annular channel circumferentially. The annular partition is provided with a steam vent. The steam vents on two adjacent annular partitions are located on opposite sides of the sealing plate between the two annular partitions.

[0004] The aforementioned patent document discloses a lithium battery recycling volatilization furnace, which solves the problems of existing volatilization furnaces that use electric heaters for heating, resulting in slow heating speed, incomplete and uneven heating, and thus poor electrolyte volatilization. However, the volatilization furnace has shortcomings in terms of waste gas treatment and furnace interior cleaning. On the one hand, the volatilization furnace generates a large amount of waste gas during the heating and volatilization process, and the design does not fully consider the effective treatment of the waste gas, which may lead to the release of harmful substances in the waste gas into the environment without sufficient purification, increasing the risk of environmental pollution. On the other hand, after the lithium battery is heated and volatilized, solid waste and electrolyte residue may remain inside the furnace, and the design of the volatilization furnace is limited in terms of facilitating the cleaning of the furnace interior, which may increase maintenance costs and time costs.

[0005] Therefore, we have made improvements to this by proposing a lithium battery recycling volatilization furnace. Utility Model Content
