Method for power battery automatic fine-quantity sorting and apparatus thereof

A method for power battery automatic fine-quantity sorting, comprising:

• S1. crushing and leveling a material, and performing a magnetic sorting processing to sort out iron powder;
• S2. performing an electrostatic processing on the material after being subjected to the magnetic sorting processing to sort out positive electrode material powder;
• S3. performing a bounce processing on the material after being subjected to the electrostatic processing to sort out collector and graphite powder, and
• wherein, a sorting apparatus based on the method for power battery automatic fine-quantity sorting, along the direction of material transmission, is successively provided with:
• a magnetic sorting device, comprising a permanent magnet rolling wheel (100), an iron powder hopper (200) is provided at the lower left of the permanent magnet rolling wheel (100);
• an electrostatic sorting device, located at the lower right of the permanent magnet rolling wheel (100), comprising a grounded roller electrode (500), a corona electrode (300) and a static electrode (400) successively provided at the upper right of the roller electrode (500), and a brush (600) in contact with the roller electrode (500) provided at the lower left, the corona electrode (300), the static electrode (400) and the brush (600) are located at 1, 2, 9 o'clock direction of the roller electrode (500) respectively;
• a bouncing sorting device, located at the lower right of the roller electrode (500), comprising a drive wheel (700), a driven wheel 710) and a conveyor belt (720), a deflecting wheel (800) and a carrier rod (810) being provided below the driven wheel (700), one end of the carrier rod (810) being connected to the deflecting wheel (800) to form an eccentric wheel mechanism, and the other end being connected to the driven wheel (710).
