Embodiment 1

[0054] figure 1 Shown is a waste lithium battery classification and crushing equipment according to a preferred embodiment of the present invention, which includes a shredder 1, a primary transmission mechanism 2, a primary vibrating screen 3, a primary vertical crusher 4, and a secondary transmission mechanism 5 , magnetic separator 6, secondary vibrating screen 7, secondary vertical crusher 8, sealing cover 9, suction duct 10, suction fan 11 and diaphragm collector 12.

[0055] The first-level transmission mechanism 2 (conveyor belt can be used) is arranged obliquely. The lower end is the feeding end located below the discharge port at the bottom of the shredder 1, and the upper end is the discharging end. The discharge opening of the vibrating screen 3 is located above the primary vertical crusher 4 .

[0056] Such as figure 2 As shown, the primary vertical crusher 4 is provided with a first central shaft 401, and the two ends of the first central rotary shaft 401 are in...

Abstract

The invention relates to waste lithium battery graded-crushing equipment and process. The equipment comprises a shredder, a suction fan and an air suction pipeline, and further comprises: a first-stage vertical crusher, a two-stage vertical crusher, a first-stage transmission mechanism, a second-stage transmission mechanism, a first-stage vibrating screen, a second-stage vibrating screen, a magnetic separator, a sealing cover and a diaphragm collector. Two stages of the vertical crushers and vibrating screens are added on the basis of an existing lithium battery shredder, thus forming a multi-stage shredding and crushing combination process for a lithium battery; rapid separation of valuable substances of waste lithium batteries is realized, and an enriched object with relatively high purity is obtained. Meanwhile, the separation effect of the vertical crushers is controlled by the arrangement of a material outlet and screens, so that the shape of a discharged material is regularized,and the subsequent physical sorting is facilitated. In addition, dissociated shells are removed by means of the magnetic separator; the sealing cover and the air suction pipeline are arranged to suckaway a lighter diaphragm and exhaust gas; finally the diaphragm is uniformly collected through the diaphragm collector to reduce environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of waste battery recovery and treatment, and in particular relates to a waste lithium battery classification and crushing equipment and process. Background technique [0002] Lithium battery materials mainly include positive electrode materials, negative electrode materials, separators, electrolytes, aluminum foil, copper foil, adhesives, etc. The resource recovery and utilization of waste lithium batteries is mainly to obtain copper foil, aluminum foil and high-value lithium compounds through mechanical crushing, hydrometallurgy, etc. Among them, lithium compounds are mainly attached to very thin aluminum foil through adhesives, and the material composition is complex. , The shape is different, both soft and hard, the traditional hammer crusher can not effectively crush it, and realize the efficient stripping of different components. [0003] The patent with publication number CN105811040A discloses a lith...
