Powder rapid cooling structure

Abstract

The utility model belongs to the technical field of material cooling, and discloses a powder material rapid cooling structure, including a lower hopper arranged at the bottom of a vertical furnace body, a discharge pipe arranged in the vertical furnace body, the lower hopper is used to receive the powder material discharged from the discharge pipe, a cooling chamber for providing a low temperature environment is arranged in the lower hopper, the cooling chamber is funnel-shaped, a discharge port is arranged at the bottom of the cooling chamber, a blowing pipe is arranged in the cooling chamber and below the pipe port of the discharge pipe, a plurality of nozzles are arranged on the blowing pipe, and the nozzles are used to blow safety gas to the powder material falling from the discharge pipe so that the powder material is blown away. The powder material rapid cooling structure achieves the purpose of cooling the powder material when it is discharged by adding a cooling chamber at the discharge port of the vertical furnace body, without the need for an additional material transfer step, thereby improving the processing efficiency and ensuring the quality of the finished product, and a blowing pipe is arranged to blow away the powder material, thereby improving the cooling effect.
