Example Embodiment

[0054] Example 1

[0055] A method for automatic and deep sorting of power batteries, comprising the following steps:

[0056] S1. The pulverized material is smoothed by the blade edge of the scraper 1300 until the material has a thickness of 1mm and then sent to the magnetic separation device. The magnetic separation device includes a permanent magnet roller 100. The speed of the permanent magnet roller 100 is 0.05m / s. When the permanent magnet roller 100 is above, the magnetic iron powder will be firmly absorbed on the roller until the belt and the roller are separated as the permanent magnet roller 100 turns to the lowest point, and the iron powder is also separated from the permanent magnet roller 100 and falls into the lower left. The square iron powder hopper 200, under the action of gravity and centrifugal force, the remaining material falls off tangentially from the permanent magnet roller 100 and enters the electrostatic separation device at the lower right;

Example Embodiment

[0059] Example 2

[0060] The steps of Embodiment 2 are the same as those of Embodiment 1, except that the rotational speed of the permanent magnet roller 100 in step S1 is 0.1 m / s. The voltage in step 2 is 20kV, the rotation speed of the roller electrode 500 is 800r / min, the linear speed of the conveyor belt 720 in step S3 is 0.2m / s, and the amplitude of the driven wheel 710 is 0.12m / s.

Example Embodiment

[0061] Example 3

[0062] The steps of Embodiment 3 are the same as those of Embodiment 1, except that the rotational speed of the permanent magnet roller 100 in step S1 is 0.2 m / s. The voltage in step 2 is 30kV, the rotation speed of the roller electrode 500 is 1000r / min, the linear speed of the conveyor belt 720 in step S3 is 0.2m / s, and the amplitude of the driven wheel 710 is 0.15m.

Abstract

The invention discloses an automatic fine and deep sorting method and device for a power battery. The sorting method comprises the following steps of S1, carrying out the crushing and leveling of a material, then carrying out the magnetic separation, and sorting out iron powder; S2, carrying out electrostatic treatment on the material subjected to magnetic separation, and separating out positive electrode material powder; S3, performing bounce treatment on the material subjected to electrostatic treatment, separating out a current collector and graphite powder, and correspondingly arranging amagnetic separation device, an electrostatic separation device and a bounce separation device. According to the method, three methods of magnetic separation, electrostatic treatment and bounce treatment are combined, high-purity separation of copper, iron, aluminum, graphite and positive electrode materials in the waste battery crushed materials is achieved, and problems that in a traditional method, metal entrainment exists, and positive electrode material powder and negative electrode material powder cannot be effectively separated are solved.

Description

technical field [0001] The invention relates to the technical field of recycling waste lithium batteries, in particular to an automatic intensive sorting method for power batteries and a device thereof. Background technique [0002] Under the current situation of massive growth of decommissioned power batteries and the stringent requirements of current environmental protection laws and regulations, higher requirements are put forward for the recycling process of power batteries. However, the sorting of materials after the power battery is broken has always been a difficult problem in the actual recycling process, and the higher-precision sorting of materials is a more difficult problem to break through. [0003] Discarded lithium batteries contain a large amount of non-renewable metal resources with high economic value, such as cobalt, lithium, nickel, copper, aluminum, etc. If the discarded or unqualified lithium batteries can be effectively recycled, it will not only reduc...
