Description

Technical Field

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

[0002] After high-temperature processing, powdered materials need to undergo necessary cooling steps before they can be processed further. Currently, powders are generally exported from processing furnaces to additional cooling boxes for cooling, which results in discontinuous production, reduced efficiency, increased equipment costs and floor space, and during the cooling process, powders will be exposed to oxygen for oxidation, and even mixed with other impurities, affecting the quality of the finished product. In addition, due to the poor fluidity of powders, they are easily bonded and adsorbed together, making it difficult to achieve consistent cooling effects on the inner and outer layers of powders.
