Problems solved by technology

Because the positive and negative electrode powders are prone to agglomeration, in the actual screening process, many positive and negative electrode powders will agglomerate together to form large particles that cannot pass through the screen, which has the disadvantages of low screening efficiency and poor effect.

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 As shown, the screening and recovery device for crushed lithium battery materials in this embodiment includes a housing 1 and a vibration drive assembly 2 for driving the vibration of the housing 1. The housing 1 has a screening chamber, and multiple screens are installed in the screening chamber. Layers of screens 3 are arranged at intervals from top to bottom, and the sieve apertures of the multi-layer screens 3 decrease layer by layer along the direction from top to bottom. The multi-layer screens 3 separate the screening chamber into A plurality of cavities 4 arranged, the upper cavity 4 is provided with a feed port 41, each cavity 4 is provided with a discharge port 42, at least one cavity 4 between adjacent two layers of screens 3 There are a plurality of scrap pieces 5 that can dance in the cavity 4 und...

Abstract

The invention discloses a crushed lithium battery screening and recycling device which comprises a shell and a vibration driving assembly used for driving the shell to vibrate, wherein the shell is provided with a screening cavity; a plurality of layers of screening meshes which are sequentially arranged at intervals from top to bottom are mounted in the screening cavity; the hole diameters of screening holes in the multiple layers of screening meshes are reduced layer by layer in the direction from top to bottom; the screening cavity is divided by the multiple layers of screening meshes into a plurality of cavities which are sequentially arranged from top to bottom; the top cavity is provided with a feeding port; each cavity is provided with a discharging port; and a plurality of crushing components capable of jumping under the action of the vibrating screen meshes are mounted in at least one cavity positioned between every two adjacent layers of screening meshes. The crushed lithium battery screening and recycling device has the advantages of being simple and compact in structure, low in cost, high in screening efficiency, and good in screening effect.

Description

technical field [0001] The invention relates to the technical field of lithium battery recycling equipment, in particular to a screening and recycling device for crushed lithium battery materials. Background technique [0002] High-temperature pyrolysis is a common treatment process for lithium battery recycling. Its main process includes several major processes of "crushing-high-temperature pyrolysis-sieving". Among them, crushing is to break lithium batteries into pieces, and high-temperature pyrolysis is to make The volatilization of the binder for bonding the pole piece and the positive and negative powder materials makes it easier to separate the pole piece from the positive and negative powder materials. Sieving is to separate the pole piece from the positive and negative powder materials. The chips are directly recycled, and the positive and negative electrode powders are further processed. In the above process, the efficiency of screening determines the efficiency o...
