Description

Technical Field

[0001] This utility model relates to a purification device for recycling, specifically a purification device for recycling waste lithium-ion batteries, belonging to the field of lithium-ion battery technology. Background Technology

[0002] Used lithium-ion batteries are a common type of electronic waste, yet they possess enormous potential for reuse. Green recycling methods for used lithium-ion batteries have become a hot topic in the environmental protection industry in recent years. There are two main methods for the green recycling of used lithium-ion batteries: recycling and remanufacturing. These methods can not only reduce resource waste but also reduce environmental pollution, thus achieving the goal of sustainable development.

[0003] A search revealed a Chinese patent with publication number CN222064214U, which discloses a purification device for recycling waste lithium-ion batteries. This invention relates to the field of battery recycling technology. The beneficial effects of this invention are: filter residue falls into the sedimentation tank, the electric push rod extends to adjust the cleaning height, springs are provided on both sides of the cleaning plate, and the springs are connected to the scraper to clean both sides, making cleaning more convenient when residue adheres to the wall. When the cleaning plate on the electric push rod contacts the bottom of the sedimentation tank, the servo motor works, driving the slider on the threaded rod to move, accelerating the cleaning, making it less prone to accumulation, avoiding blockage of the discharge pipe, and improving work efficiency.

[0004] While the above solutions can adjust the cleaning height to prevent accumulation, avoid clogging the discharge pipe, and improve work efficiency, the recycling purification device in the above patents is difficult to handle the waste gas generated during crushing.
