Problems solved by technology

[0029] In the pretreatment stage of waste lithium batteries, it is necessary to screen the crushed materials. In the prior art, mining sorters are generally used for screening, and the fineness of the sorting is low. Increasing the fineness will greatly reduce the sorting. Efficiency, so it is necessary to provide a screening device that is efficient compared to existing sorting machines

Abstract

The invention discloses a cathode material pretreatment and screening mechanism of a waste lithium battery wet recovery production line. The pretreatment and screening mechanism comprises a pluralityof shaking table units which are sequentially arranged from top to bottom, wherein the shaking table units comprise table frames, the shaking table units are arranged on a shaking table base, a tableframe support of the shaking table unit at the bottommost position is installed on the shaking table base, and the table frames of adjacent shaking table units are connected through supporting brackets; and a centrifugal system is arranged at the bottom of the shaking table base, the centrifugal system comprises a rotating disc, a base and a centrifugal driving mechanism, the rotating disc is arranged at the top of the base, a groove matched with the rotating disc in clearance fit is formed in the top of the base, and the rotating disc is embedded in the base. According to the mechanism, the shaking table units are rotated through the centrifugal system to sort materials comprehensively, precision can be improved with the need to reducing the operation speed of shaking tables, the mechanism is suitable for screening materials after lithium battery pretreatment, and the mechanism is worthy of wide popularization.

Description

technical field [0001] The invention relates to the technical field of waste lithium battery recycling, in particular to a positive electrode material pretreatment and screening mechanism for a waste lithium battery wet recovery production line. Background technique [0002] With the increasing shortage of global fossil resources and the urgent need for environmental protection, the development of electric vehicles to reduce resource consumption and reduce environmental pollution is gradually becoming a broad consensus. In recent years, the state has given great support to electric vehicles, which has led to a sharp increase in the production of electric vehicles. As of 2016, China has produced a total of 1.014 million electric vehicles, and the number of electric vehicles in the market is also close to 1 million. [0003] However, the large number of electric vehicles entering the market will inevitably bring about the problem of recycling and disposal of batteries at the e...
