Description

Technical Field

[0001] The invention relates to the technical field of waste battery recycling, and in particular to an electrochemically active repair device for failed lithium manganese iron phosphate. Background Art

[0002] With the widespread application of lithium iron phosphate batteries, the numerous lithium iron phosphate battery products on the market have brought about a large number of lithium iron phosphate battery wastes. Directly discarding these battery wastes not only pollutes the environment, but also causes a waste of resources. Therefore, for lithium iron phosphate battery wastes, electrochemical active repair methods are usually used to regenerate the failed lithium iron phosphate batteries. Therefore, an electrochemical active repair device for failed lithium iron phosphate is needed.

[0003] The existing electrochemical activity repair method of failed lithium iron manganese phosphate is usually to add lithium, manganese, iron and carbon source into the failed lithium iron manganese phosphate, mix them evenly, and finally calcine them under an inert atmosphere to finally repair the electrochemical activity of the lithium iron manganese phosphate. While ensuring the electrochemical activity repair effect, the pollution emissions of this process are reduced, ensuring that the electrochemical activity repair process of the lithium iron manganese phosphate is green and environmentally friendly.

[0004] However, during the above-mentioned repair method, whether it is the failed lithium iron manganese phosphate or the subsequently added lithium, manganese, iron and carbon source, they are not put into the repair equipment in the elemental state for mixing separately, but most of them are mixed in the form of solid. Generally, corresponding grinding equipment or ball mills are used to perform preliminary crushing and grinding. However, during the stirring and mixing process, the mixing efficiency between the fine granular materials is not effectively guaranteed. At the same time, there is a lack of corresponding grinding steps in the stirring and mixing process, and it is difficult to crush and grind the crystals or solids that may appear in the reaction process.

In order to achieve the grinding effect, a transmission assembly is provided, which cooperates with the return spring 19 and the return spring 25, so that under the transmission of the wave contact groove 22 and the contact wheel 21, when the positioning frame 14 rotates with the rotating rod 5 as the rotation center, the transmission rod 16 drives the roller 17 to perform a small reciprocating motion in the horizontal direction, so that the roller 17 can also grind in the horizontal direction during rolling, thereby improving the operating efficiency of the roller 17 and ensuring the mixing effect of the device. In addition, in order to improve the turbulence effect of the roller 17 on the mixing and stirring of materials, By providing a spoiler component in cooperation with the elastic telescopic rod 28, during the rolling process, as the rolling roller 17 rotates, the slide cylinder 29 in contact with the bottom inner wall of the body 1 or the metal partition will slide on the slide cylinder 27 in the horizontal direction due to friction.
