Description

Technical Field

[0001] This utility model relates to the field of cathode material pulverization technology, specifically to an airflow pulverization device for high-nickel single-crystal ternary cathode materials. Background Technology

[0002] Airflow milling of cathode materials is a key material processing step in lithium-ion battery production. High-speed airflow enables ultra-fine milling, significantly improving material performance.

[0003] Chinese patent CN215277805U discloses an airflow pulverizing device for coating materials. The device includes a fixed barrel containing a rotating conical barrel rotatably mounted inside. Both the fixed barrel and the rotating conical barrel have upward-facing openings. Multiple first air diffusers are evenly distributed in a ring on the outer wall of the rotating conical barrel, adhering to the outer wall and maintaining a vertical orientation. Multiple nozzles are evenly arranged on the first air diffusers, extending into the rotating conical barrel with their nozzles pointing along the inner circumference of the rotating conical barrel. This device effectively improves the diversity of pulverization methods for coating materials, increases the impact strength between materials, and enhances the pulverization effect. Simultaneously, the device can continuously pulverize incompletely pulverized materials, ensuring thorough pulverization and improving the regularity and quality of the pulverization process.

[0004] However, it still has the following drawbacks: during the air jet milling process, the micronized particles are prone to generating electrostatic forces, easily adhering to the inner wall of the tank, and gradually encroaching on the internal space of the milling chamber, affecting the operation of the milling device. To address this problem, we propose an air jet milling device for high-nickel single-crystal ternary cathode materials. Utility Model Content

[0005] The purpose of this invention is to provide a high-nickel single-crystal ternary cathode material airflow pulverization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-nickel single-crystal ternary cathode material airflow pulverizing device, comprising a tank, wherein a cleaning device is provided on the tank, and the cleaning device includes a power unit;

[0007] The power unit includes a dual-head motor and a cleaning brush. A bracket is fixedly connected to the outer surface of the dual-head motor, and a slide rod is fixedly connected to the outer surface of the cleaning brush.

[0008] A drive unit is provided at the bottom of the tank;

[0009] The drive unit includes a lifting plate, which is threaded onto the outer surface of the output shaft below the dual-head motor, and a U-shaped bracket is fixedly connected to the bottom surface of the lifting plate.

[0010] A further improvement is that the power unit also includes a mounting plate, a spring, a gear, a gear ring, a sealing gasket, a rotating cylinder, and a sealing sleeve. The outer surface of the slide rod extends into the interior of the mounting plate and slides in connection with the inner wall of the mounting plate. By setting up a cleaning brush, a slide rod, and a mounting plate, the cleaning brush is used to clean the inner wall of the tank.

[0011] A further improvement is that one end of the spring is fixedly connected to the outer surface of the slide rod, and the other end of the spring is fixedly connected to the inner wall of the mounting plate. By setting the spring, the elastic force of the spring can be used to facilitate the cleaning of the inner wall of the tank with different diameters.

[0012] A further improvement is that the outer surface of the sealing gasket is fixedly connected to the inner wall of the sealing sleeve, the sealing sleeve is slidably fitted on the outer surface of the rotating cylinder, the outer surface of the sealing sleeve is rotatably connected to the inner wall of the tank through a sealing bearing, and the top surface of the rotating cylinder is fixedly connected to the bottom surface of the mounting plate, so that the rotating cylinder can also rotate when sliding up and down, which facilitates the cleaning brush to clean the inner wall of the tank.

[0013] A further improvement is that the top surface of the bracket is fixedly connected to the bottom surface of the tank, the gear is fixedly sleeved on the outer surface of the output shaft above the dual-head motor, and the gear ring is fixedly sleeved on the outer surface of the sealing sleeve. By setting up the dual-head motor, gear, and gear ring, the dual-head motor is started, which drives the sealing sleeve, rotating cylinder, mounting plate, and cleaning brush to rotate, so that the cleaning brush can clean the inner wall of the tank.

[0014] A further improvement is that the drive unit also includes a rotating shaft, a sleeve, and an arc-shaped brush. The sleeve is fixedly fitted on the outer surface of the rotating cylinder, and the inner wall of the lifting plate extends into the sleeve and is slidably connected to the inner wall of the sleeve. By setting up the lifting plate and the sleeve, the dual-head motor is started, and the lifting plate is driven to move upward by the output shaft below the dual-head motor, which facilitates the upward movement of the rotating cylinder, the mounting plate, and the cleaning brush, making it easier to clean the inner wall of the tank.

[0015] A further improvement is that the bottom surface of the rotating shaft is fixedly connected to the inner wall of the U-shaped bracket, the outer surface of the top end of the rotating shaft rotates through the bottom surface of the rotating cylinder via the first bearing and extends into the interior of the rotating cylinder, the outer surface of the top end of the rotating cylinder rotates through the bottom surface of the mounting plate via the second bearing and extends above the mounting plate, and the outer surface of the arc-shaped brush is fixedly connected to the outer surface of the rotating shaft. By setting up the arc-shaped brush, the rotating shaft, and the U-shaped bracket, when the rotating cylinder, the mounting plate, and the cleaning brush move upward and rotate, the rotating shaft and the arc-shaped brush only move upward and do not rotate, so that the arc-shaped brush cleans the top surface of the mounting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-nickel single-crystal ternary cathode material airflow pulverizing equipment, through the setting of a support, a dual-head motor, a mounting plate, a cleaning brush, a slide bar, a gear, a gear ring, a sealing gasket, a rotating cylinder, a sealing sleeve, a lifting plate, and a sleeve, enables the dual-head motor to be started. The output shaft of the dual-head motor drives the sealing sleeve and the mounting plate to rotate through the gear and gear ring, so that the cleaning brush cleans the inner wall of the tank and scrapes off the high-nickel single-crystal ternary cathode material adhering to the inner wall of the tank. The output shaft at the bottom of the dual-head motor drives the lifting plate to move upward, which in turn moves the rotating cylinder upward and moves the cleaning brush upward to clean the inner wall of the tank. By setting a spring, the elastic force of the spring is used to make the cleaning brush clean the inner wall of the tank with different diameters. By setting a rotating shaft, a U-shaped support, and an arc-shaped brush, when the mounting cylinder and the mounting plate rotate, the arc-shaped brush scrapes off the high-nickel single-crystal ternary cathode material on the top surface of the mounting plate.

One end of the spring 216 is fixedly connected to the outer surface of the slide rod 215, and the other end of the spring 216 is fixedly connected to the inner wall of the mounting plate 213. By setting the spring 216, the elastic force of the spring 216 is used to make the cleaning brush 214 clean the inner wall of the tank 1 of different diameters.
