Description

A stirring device for processing lithium battery raw materials capable of preventing internal residues

Technical Field

The utility model relates to the technical field of lithium battery raw material processing, in particular to a stirring device for lithium battery raw material processing which can prevent internal residue.

Background Art

The stirring of lithium battery raw materials is to add active substances, conductive carbon black, dispersants, binders, additives and other components into the mixer in a certain proportion and order, and mix them together under the mechanical action of the stirring paddle and dispersion disk, such as tumbling, kneading, and shearing, to form a uniform and stable solid-liquid suspension system. Key battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. There are lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Hammer battery is the abbreviation of lithium-ion battery. Currently, as a new type of energy storage battery, it is gradually replacing traditional lead-acid batteries.

According to patent CN213611092U, a stirring device for processing lithium battery raw materials that can prevent internal residuals includes a fixed base, a second fixed plate, a discharge port, a rubber plug and a baffle plate. A support frame is fixed on the top of the fixed base, a second motor is connected to the front end of the second rotating shaft, a second fixed plate is fixed below the second motor, and the second fixed plate is connected to a mixing box. A discharge port is provided on the side wall of the mixing box, and a rubber plug is provided in the discharge port. The end of the telescopic rod is connected to the baffle plate. The stirring device for processing lithium battery raw materials that can prevent internal residuals from leaking is provided with a first rotating shaft, and a stirring plate is installed on the surface of the second rotating shaft. The size of the stirring plate matches the size of the mixing box; and the shape of the mixing box is circular. When the second rotating shaft rotates, the end of the stirring plate cleans the inner wall of the mixing box to prevent the inner wall of the mixing box from residues.

In this patent, the swing of the stirring device is controlled by a motor, which has high requirements on the motor performance. It is difficult for the motor to achieve short-range and high-frequency reciprocating rotation, which makes the device less feasible and the stirring efficiency lower. In addition, in this patent, when cleaning the inner wall, the inner wall of the stirring box is cleaned by a stirring plate. The contact between the stirring plate and the inner wall will cause the raw materials to contact more closely with the inner wall of the stirring box during stirring, which is not convenient for subsequent cleaning work.
