Description

Technical Field

[0001] The utility model relates to the field of rapid cooling devices, in particular to a rapid cooling device for refined slag. Background Art

[0002] Refined slag refers to the technology of mixing raw materials in a certain proportion and particle size, heating at a temperature below the melting point of the raw materials, sintering the raw materials together, and then crushing them into particles. The main components are CaO-CaF2-based, CaO-Al2O3-based, and CaO-Al2O3-SiO2-based. The forms of refined slag mainly include sintered type, pre-melted type and mixed type. In the prior art, the Chinese utility model patent with the public document number CN215810250U discloses a rapid cooling device for pre-melted refined slag. The spiral blades inside the rotating drum in the utility model can block the refined slag to prevent the refined slag from sliding too fast and affecting its cooling effect. The rotating speed of the rotating drum can be reduced, and the residence time of the refined slag inside the feeding channel can be increased to reduce the length of the rotating drum, thereby reducing the volume of the box body and reducing the floor space of the device.

This part of the unqualified refined slag is mixed in the material, which is likely to affect the subsequent processing process and reduce the quality of the product, so improvement is needed.
