Winnowing screening device for waste power battery

Abstract

The invention discloses a winnowing screening device for a waste power battery. The winnowing screening device comprises a machine frame, a winnowing device and a layered sieve; the layered sieve comprises a light material layering sieve, a heavy material layering sieve and a transmission device; the machine frame is of a frame structure welded by angle iron, and is divided into an upper layer, amiddle layer and a lower layer, the winnowing device is installed on the upper layer, and the layered sieve is installed in the middle layer; and the winnowing device comprises a feed hopper, an axialflow fan and a winnowing bin. According to the winnowing screening device, during operation, crushed waste power battery materials enter the hopper, wind power of the axial flow fan blows the waste power battery materials in an upwards inclined mode, and the waste power battery materials fall into the lower light material layering sieve and the heavy material layering sieve from the winnowing binin a parabolic shape, carbon powder in the waste power battery materials passes through meshes of the light material layering sieve and the heavy material layering sieve to fall into a discharging opening below, light-weight sheet aluminum foil is a sieve residue of the light material layering sieve, heavier flaky copper foil is a sieve residue of the heavy material layering sieve, so that classified collection of the waste power battery materials is realized.

Description

technical field [0001] The invention belongs to the field of recycling and processing equipment for waste power batteries, in particular, it relates to a winnowing and screening device for waste power batteries. Background technique [0002] Since the 21st century, new energy vehicles have become one of the key development directions for countries around the world to achieve energy conservation and emission reduction. In recent years, my country's new energy automobile industry has developed rapidly with the support of government policies. By 2020, my country's annual output of new energy vehicles will reach 2 million, and the cumulative output will exceed 5 million. With the rapid increase in the use of new energy vehicles, the amount of scrapped power batteries will increase year by year. By 2020, the accumulative waste of power batteries in my country will reach 120,000-170,000 tons. If the waste power battery is not disposed of properly, the organic matter and preciou...
