Description

Technical Field

[0001] The utility model relates to the technical field of slurry processing, in particular to a cooling device for slurry. Background Art

[0002] Slurry is a diverse concept with different definitions and compositions depending on the application field. Generally speaking, slurry is a mixture containing solid particles dispersed in a liquid, forming a semi-fluid or viscous state. This mixture can be processed through different processes, such as stirring, grinding, etc., to evenly distribute the solid particles in the liquid and form a stable suspension system.

[0003] In production, the cooling and freezing treatment of slurry is mainly to control the reaction temperature, prevent the degradation of heat-sensitive components, improve the mixing and dispersion characteristics of the material, promote specific crystallization processes, ensure safe production, and facilitate subsequent operations such as filtration and drying. A low-temperature environment helps maintain chemical stability, optimize product texture, reduce energy consumption, and is necessary in some cases, such as when dealing with high-viscosity or heat-sensitive materials, to achieve more efficient and high-quality production goals.

[0004] A slurry cooling device is a device specifically used to reduce and control the temperature of slurry, and is widely used in many industrial fields such as chemical industry, food processing, battery manufacturing, pharmaceutical industry, and building materials. The design of these devices aims to efficiently remove the excess heat generated by the slurry during the production process, ensure that the slurry is maintained within the ideal temperature range, and guarantee product quality, improve production efficiency and safety.

[0005] Although the existing slurry cooling devices have the cooling effect on the slurry, since the existing slurry cooling usually places the slurry in a closed storage tank, the heat dissipation efficiency is insufficient, which affects the heat exchange efficiency between the slurry and the cooling medium. Therefore, to overcome the above deficiencies, a cooling device for slurry is provided. Summary of the Utility Model
