Waste lithium battery sorting and recycling equipment

Abstract

The invention belongs to the technical field of lithium battery recycling, and particularly relates to waste lithium battery sorting and recycling equipment. The waste lithium battery sorting and recycling equipment comprises a box, a first-level sorting unit and a second-level sorting unit. A circular-platform-shaped groove is formed in the middle position of the upper surface of the box. A rectangular groove is formed in the middle position of the lower surface of the box. A filter hole is formed in the part, between the circular-platform-shaped groove and the rectangular groove, of the box,and a cover plate is arranged above the box. The first-level sorting unit is located in the circular-platform-shaped groove of the box and used for conducting first-time pulverizing and screening onwaste lithium batteries, and plastic and metal composite materials are separated out. The second-level sorting unit is located in the rectangular groove in the lower portion of the box and used for pulverizing and screening the metal composite materials again, and positive and negative electrode materials and waste residues are separated out, wherein the metal composite materials are obtained after screening through the first-level sorting unit. The waste lithium battery sorting and recycling equipment achieves linkage between two levels of crushing, the crushing effect is good, and the energyutilization rate is high.

Description

technical field [0001] The invention belongs to the technical field of lithium battery recycling, and in particular relates to sorting and recycling equipment for waste lithium batteries. Background technique [0002] Since its commercialization, lithium batteries have been widely used in civilian and military fields, such as cameras, mobile Phones, notebook computers, and portable thermometers, etc., while lithium batteries are also one of the preferred light-weight high-energy power batteries for electric vehicles. The recycling and reuse of waste batteries can not only avoid the waste of resources and realize the best use of materials, but also reduce the pollution of metal ions contained in waste batteries to the environment. Due to the shortage of resources and the need for environmental governance, countries all over the world have attached great importance to the recycling of waste batteries. The management of waste batteries is urgent. How to make waste batteries re...

Problems solved by technology

[0004] In the above-mentioned patent documents, the two-stage crushing method is adopted in this technical solution to realize the separation of the metal and the positive electrode material, but the crushing device used is likely to cause damage to the coarse crushing separator and generate a lot of noise due to the large impact force during the rotating crushing. At the same time, due to the use of multiple power sources, the linkage between the two stages of crushing is not strong, and the energy utilization rate is not high.
