Smashing device for scrapping lithium-ion power batteries

Abstract

The invention provides a smashing device for scrapping lithium-ion power batteries. The device comprises a smashing barrel, at least one water spraying head, a rotor, a plurality of hammer heads and a screen mesh. A feed inlet is formed in one side of the upper part of the smashing barrel; an exhaust gas discharge hole is formed in the other side of the upper part of the smashing barrel; the water spraying heads are arranged on the inner wall of the smashing barrel; water spraying directions of the water spraying heads respectively towards the central part of the smashing barrel; the rotor is fixed to the side wall of the smashing barrel, and can rotate in a vertical face vertical to a horizontal face; the hammer heads are arranged on the rotor; the screen mesh is arranged under the rotor and is arranged on the inner wall of the smashing barrel; and a mesh surface of the scree mesh divides the inner space of the smashing barrel into an upper layer above the mesh surface and a lower surface under the mesh surface. The smashing device provided by the invention is simple in structure, low in manufacturing cost and better in smashing effect.

Description

technical field [0001] The invention relates to battery crushing technology, in particular to a crushing device for scrapped lithium-ion power batteries. Background technique [0002] Lithium-ion power battery is a new type of high-energy battery successfully developed in the 20th century. The negative electrode of this battery is metallic lithium, and the positive electrode uses MnO 2 , SOCL 2 , (CFx)n, etc., entered into practical use in the 1970s. Because of its advantages of high energy, high battery voltage, wide operating temperature range, and long storage life, it has been widely used in military and civilian small electrical appliances. Lithium-ion power batteries have partially replaced traditional batteries in mobile phones, portable computers, video cameras, cameras, etc. Large-capacity lithium-ion batteries have been tried in electric vehicles and are one of the main power sources for electric vehicles. They have been used in satellites, aerospace and energy ...

AI Technical Summary

Problems solved by technology

However, although there are many types of crushing devices for lithium-ion power batteries, they are either complex in structure and high in manufacturing costs, or simple in structure but poor in crushing effect.
