The vacuum mixer of battery paste is the key equipment for mixing all kinds of battery paste in battery production, which plays a decisive role in the performance and quality of the battery.
It works by using a vacuum environment and an efficient stirring mechanism. Before mixing, the equipment first pumped the mixing chamber to the vacuum state through the vacuum pump to remove air and water, to avoid the problem of oxidation and agglomeration of the slurry in the mixing process. Then, the mixing device begins to work, usually consisting of mixing blades of different speeds and steering. The high-speed rotating dispersion blade is responsible for breaking up the large particle material and making it fine; The low-speed stirring blade promotes the overall circulation of the slurry, promotes the uniform distribution of the material, realizes the full mixing of different components, and ensures the consistency and stability of the slurry.
From the perspective of structure, it mainly includes the following parts. The vacuum system is composed of vacuum pump, vacuum pipe and vacuum valve to ensure a high vacuum degree in the mixing chamber. The mixing system is equipped with a variety of mixing blades, such as serrated dispersion paddle, anchor type mixing paddle, etc., to meet different mixing needs. The mixing chamber adopts sealing design, mostly made of stainless steel, with good corrosion resistance and sealing. The control system is equipped with an operation panel, which can accurately set stirring time, speed, vacuum degree and other parameters to achieve automatic operation.
This device has outstanding performance advantages. First of all, the mixing uniformity is high, which can make the components of the battery paste evenly dispersed and improve the battery performance. Secondly, mixing in a vacuum environment effectively avoids the contact between the slurry and the air, prevents impurities from mixing, and ensures the purity and stability of the slurry. Moreover, the production efficiency of the equipment is high, and a large amount of slurry can be mixed in a short time to meet the needs of large-scale production.
During operation, first check whether the components of the equipment are normal, and then add the required materials to the mixing chamber in proportion. After closing the mixing chamber, start the vacuum pump. After reaching the predetermined vacuum degree, set stirring time, speed and other parameters in the control system according to the slurry characteristics, and start the stirring device. After mixing, stop stirring first, then slowly remove the vacuum, and finally discharge the material.
