Description

Technical Field

[0001] The utility model relates to the technical field of power batteries, in particular to a disperser for producing power battery cold drum coatings which is easy to clean. Background Art

[0002] Power batteries are core components of new energy vehicles and energy storage equipment, with high energy density, long cycle life and excellent safety performance. The performance of power batteries directly affects the range of electric vehicles and the stability of energy storage systems. Cold drum coating technology is widely used in the production of battery electrode materials. Cold drum coating can form a uniform and dense coating on the surface of electrode materials to improve the conductivity and durability of the battery. When producing cold drum coating for power batteries, the disperser is one of the key equipment. The disperser uses high-speed shearing and mixing to evenly disperse the coating materials (such as nanoparticles, conductive agents, etc.) in the solvent to form a stable suspension. This process is crucial to the uniformity and performance of the coating material. The performance of the disperser directly affects the quality of the coating and the overall performance of the battery.

[0003] The dispersers currently on the market have some shortcomings when it comes to cleaning the rotor disc. For example, common dispersers and rotor discs are fixedly installed, making it difficult to clean the rotor disc and shearing blades. The rotor disc often has residual coating material and can only be rinsed with clean water immersed in the disperser barrel. Due to incomplete cleaning, the residual coating material may affect the quality of subsequent batches of products, resulting in adverse production impacts and potential quality risks.

[0004] Therefore, there is an urgent need for a disperser for the production of power battery cold drum coating that is easy to clean to solve the technical defects raised in the above-mentioned technology. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disperser for the production of power battery cold drum coating that is easy to clean, comprising a hydraulic rod and a top plate, the top end of the hydraulic rod is fixedly connected to the top plate, the top end of the top plate is fixedly connected to a variable speed motor, the output end of the variable speed motor is fixedly connected to a drive shaft, the bottom end of the top plate is fixedly connected to a connecting piece, the bottom end of the connecting piece is fixedly connected to a cylinder cover, the bottom end of the cylinder cover is equipped with a bearing, the bottom end of the drive shaft passes through the bearing and is fixedly connected to a rotating shaft, the bottom end of the rotating shaft is fixedly connected to a fixed head, the bottom end of the fixed head is fixedly connected to a rotor disk, the left side of the hydraulic rod is a cylinder, a group of legs are installed on each side of the cylinder, and a high-pressure nozzle is installed on the left side of the inner wall of the cylinder.

[0007] Furthermore, the fixed head and the rotor disk are fixed by screws, and a plurality of groups of shearing and crushing knives are distributed in an annular manner around the outer wall of the rotor disk.

[0015] (1) A hydraulic rod, a top plate, a rotor disc, and a high-pressure nozzle are provided. After the machine is used, the top plate is driven to rise by the hydraulic rod. When the rotor disc rises to the height of the high-pressure nozzle inside the cylinder, the variable speed motor drives the rotating shaft to rotate slowly. At this time, the high-pressure nozzle sprays cleaning water introduced from the outside to wash the rotor disc at high speed, and cleans the surface materials of multiple groups of shearing and crushing knives distributed in an annular manner around the outer wall of the rotor disc.

During cleaning, the high-pressure water pump draws out cleaning water and sprays it onto the rotor disk through the high-pressure nozzle. When the rotor disk is cleaned, it rises and the high-pressure nozzle continues to spray and clean the inner wall of the cylinder. Waste water is discharged from the waste water pipe. Through the design of the heating layer and the electric heating wire, the combination of the high-pressure water pump and the high-pressure nozzle, the cleaning process is more thorough and efficient. Not only the rotor disk is cleaned, but also the inner wall of the cylinder can be cleaned. It is suitable for the high-standard cleaning requirements of power battery cold drum coating production and reduces the labor cost required for manual cleaning.
