The invention provides a
lithium battery material
powder demagnetization device. The
lithium battery material
powder demagnetization device comprises a
barrel body, a material separating apparatus anda vibrating apparatus. A first magnetic pole and a second magnetic pole are symmetrically arranged on the two sides of the
barrel body, the central connecting line of the first magnetic pole and thesecond magnetic pole is parallel to the horizontal plane, a plane which penetrates through the axis of the
barrel body and is perpendicular to the central connecting line is defined as a first plane,at least two magnetic material absorbing
layers are arranged inside the barrel body, each magnetic material absorbing layer comprises 2k first
metal bars which are arranged in the direction from the first magnetic pole to the second magnetic pole horizontally in sequence, the 2k first
metal bars are symmetrically arranged using the first plane as a symmetric plane, gaps which are used for lithiumbattery material
powder to pass are formed between the adjacent first
metal bars, the first metal bars are made from metal magnetic materials, the first metal bars comprise first lateral sides and second lateral sides, the second lateral sides of the first metal bars all face the first plane, and the first lateral sides are all back to the first plane; and the polarity of the first magnetic pole and the polarity of the second magnetic pole are opposite.
