Description

Technical Field

[0001] The utility model relates to a cooling technology for a mixer, belongs to the field of new energy, and specifically relates to a water cooling system for a mixer. Background Art

[0002] The mixer has the basic function of mixing and dispersing materials. In the new energy lithium battery industry, the mixer is often used to make lithium battery mortar. In the process of making lithium battery mortar, the mixer will generate a lot of high temperature heat. The traditional rubber sealing method will not be applicable to the production of lithium battery mortar. In addition, the rubber seal may deteriorate or melt after being heated at high temperature, which is easy to cause pollution to the slurry. The Chinese invention patent with patent number 2024105868989 discloses a rotary container mixer, in which the mixing container of the rotary container mixer is closed by the mixing container cover and the two are driven to rotate synchronously; at this time, the mixing container and the mixing container cover are relatively stationary, realizing non-differential integral rotation, and the seal required for the mixed closed working environment is converted from friction dynamic seal to static seal, thereby effectively solving the problem of poor high temperature resistance of rubber seal and easy pollution to slurry. In addition, in the process of making lithium battery mortar, the mixer has strict range control of temperature. In the process of slurry production, heat will be generated, causing the slurry temperature to rise rapidly, exceeding the process allowable range, so the slurry needs to be temperature controlled. At present, the existing mixer only has a cooling structure on the pot body. During cooling, the material in the center of the mixing container cools down slowly, the material temperature cannot be fully controlled, the cooling effect is not good, and the range of materials that the mixer can be used to mix has certain limitations.
