Description

Technical Field

[0001] The utility model relates to the technical field of battery production process, in particular to a double-tank intercommunication device for battery core slurry. Background Art

[0002] The battery cell slurry needs to go through a series of processing steps before it can be used in battery manufacturing. The battery cell slurry is generally placed in a slurry tank. The battery cell slurry tank has important functions such as raw material mixing, slurry storage, slurry transportation and slurry quality control.

[0003] After searching, a slurry tank device with an existing announcement number of CN114160523A is found, which includes a slurry tank and a plurality of high-frequency ultrasonic vibrators, which are installed on the outer wall of the slurry tank. The high-frequency ultrasonic vibrators are used to generate high-frequency vibrations to the slurry tank. The slurry attached to the slurry tank falls off under the high-frequency vibration, thereby achieving the effect of quickly cleaning the slurry tank.

[0004] The tank body of the existing slurry tank device is generally a single tank. The raw materials enter the single tank and form a single operating system through pipeline components. Once the slurry tank and pipeline components are abnormal or fail, it will directly lead to system paralysis, and there is a risk of material precipitation and scrap. At the same time, there are problems such as slow feeding speed, low production efficiency, difficulty in quickly switching the supplied raw materials, and insufficient adaptability of the production plan.
