Description

PROCESSING EQUIPMENT FOR HIGH-NICKEL NICKEL-COBALT-
MANGANESE LITHIUM TERNARY CATHODE MATERIALS
Technical Field
The present invention relates to the technical field of ternary material preparation, particularly to a processing equipment for high-nickel nickel-cobalt-manganese lithium ternary cathode materials.
Background Technology
High-nickel nickel-cobalt-manganese lithium ternary cathode material is a new type of lithium-ion battery cathode material, with advantages such as high energy density, high power density, good cycling stability, and low-temperature performance.
It is widely used in power batteries, energy storage batteries, and high-capacity consumer electronic devices. The high-nickel nickel-cobalt-manganese lithium ternary cathode material contains nickel, cobalt, and manganese as active metal elements, and lithium as an alkali metal element. The proportion of these elements can be adjusted according to specific requirements, but typically, the content of nickel is relatively high.
Therefore, it is referred to as high-nickel ternary cathode material. Its crystal structure is layered, which facilitates the de-intercalation and intercalation of lithium ions, thereby providing high specific capacity and good cycling performance. During the processing of high-nickel NCM ternary cathode material, a stirring device is required to precisely measure and uniformly mix the raw materials, ensuring consistency in the chemical composition and physical properties of the material.
Existing high-nickel nickel-cobalt-manganese lithium ternary cathode material processing stirring equipment has the following defects: first, due to the material's characteristic differences, such as granularity, density, and non-uniformity in shape, traditional stirring methods often fail to ensure thorough mixing of the materials; this directly leads to inconsistent product performance, affecting the overall performance of the batteries; second, high-nickel NCM ternary cathode material, due to its unique chemical properties, has certain corrosive and abrasive characteristics, which pose a 0008329 severe challenge to the durability of stirring equipment; existing stirring devices often require frequent maintenance during prolonged use to withstand material corrosion.
However, the disassembly process of these devices is quite complex, increasing the difficulty and cost of maintenance.
Summary of the Invention
The objective of the present invention is to provide a processing equipment for high-nickel nickel-cobalt-manganese lithium ternary cathode materials to solve the problems mentioned in the background technology.
To solve the above technical problems, the present invention provides the following technical solution: a processing equipment for high-nickel nickel-cobalt- manganese lithium ternary cathode materials, comprising a base, wherein the upper surface of the base is fixedly connected to an outer barrel, within which an inner barrel is disposed. An upper seat is arranged on the outer barrel, and a main stirring shaft is sleeved on the upper seat. A main gear is fixedly connected to the main stirring shaft, which is meshed with a planetary gear. The inner wall of the upper seat is provided with outer tooth, and the planetary gear is meshed with the outer tooth. The planetary gear is fixedly connected to a sub-stirring shaft.
As a further technical solution of the present invention, the outer barrel is sleeved with a rotating seat, and the outer wall of the rotating seat is provided with a limiting ring, which is sleeved onto the inner wall of the outer barrel. The upper surface of the rotating seat is fixedly connected to a positioning block, and the positioning block is clamped to the lower surface of the inner barrel.
As a further technical solution of the present invention, a first motor is fixedly connected inside the base, and the output end of the first motor is fixedly connected to a first bevel gear. The first bevel gear is meshed with a second bevel gear, and the second bevel gear is sleeved with a timing belt. The timing belt is connected to a spindle, which is fixedly connected to the rotating seat.
As a further technical solution of the present invention, a stirring plate is fixedly 0008329 connected to the inner wall of the inner barrel, and the stirring plate is provided with a through slot and through holes.
As a further technical solution of the present invention, a fixed frame is fixedly connected to the upper surface of the upper seat, and a second motor is fixedly connected to the fixed frame. The output end of the second motor is fixedly connected to the main stirring shaft.
As a further technical solution of the present invention, a connecting pillar is fixedly connected to the upper surface of the base, and one end of the connecting pillar is fixedly connected to a fixed plate. The upper surface of the fixed plate is fixedly connected to a hydraulic cylinder, and the output end of the hydraulic cylinder is fixedly connected to the fixed frame.
As a further technical solution of the present invention, one end of the main stirring shaft is rotatably connected to a synchronizer, and the synchronizer is rotatably connected to the sub-stirring shaft.
Compared with the existing technology, the beneficial effects achieved by the present invention are: the invention is designed with a composite stirring structure, and through the planetary transmission structure, the main stirring shaft performs stirring while the sub-stirring shaft not only rotates independently but also revolves around the main stirring shaft, forming an efficient stirring mode. In addition, the inner barrel rotates in the opposite direction to the aforementioned revolving stirring motion, further enhancing the stirring effect and speed. Furthermore, the collaborative operation of the stirring plate and the sub-stirring shaft optimizes the stirring process, ensuring that the raw materials can be mixed more thoroughly than ever before. This guarantees the uniformity of the high-nickel nickel-cobalt-manganese lithium ternary cathode material, and the inner barrel is easy to disassemble, greatly reducing the complexity and cost of equipment maintenance.

Working Principle: When the high-nickel nickel-cobalt-manganese lithium ternary cathode material is processed and stirred using the present invention, the raw materials are first added to the inner barrel 11. The inner barrel 11 is fixed to the rotating seat 8 by the positioning block 10. During stirring, the hydraulic cylinder 15 on the fixed plate 14 drives the upper seat 12 to lower along the connecting pillar 13, covering the outer barrel 2 and the inner barrel 11. The second motor 17 drives the main stirring shaft 18 to rotate, stirring the materials in the inner barrel 11. At the same time, the main stirring shaft 18 drives the planetary gear 20 to rotate via the main gear 19, and the planetary gear 20 performs a revolution along the meshed outer tooth 21, achieving both self-rotation and revolution. The first motor 3 inside the base 1 drives the second bevel gear 5 to rotate via the first bevel gear 4.

The stirring rod on the sub-stirring shaft 22 passes through the through slot 25 on the stirring plate 24, further shearing the raw materials in the barrel, and the through hole 26 allows material flow. When the inner barrel 11 needs to be disassembled for maintenance, the upper seat 12 can be opened to easily remove the inner barrel 11 for the corresponding maintenance work. The synchronizer 23 is used to connect the main stirring shaft 18 and the sub-stirring shaft 22.
