Description

Technical Field

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

[0002] Molecular sieves are materials that contain precise and single tiny pores that can be used to adsorb gases or liquids. Molecules small enough can be adsorbed through the pores. Molecular sieves need to be cooled during production.

[0003] For example, a molecular sieve cooling device with patent number CN210320833U includes a cooling box, a feed hopper is provided on the upper end surface of the cooling box, a regulating valve is provided on the neck of the feed hopper, a fan is provided in the middle of the upper end surface of the cooling box, and a motor box is provided on one side of the cooling box. The above document still has shortcomings. When in use, by providing a material shifting plate, the motor can be started during the cooling process so that the material shifting plate moves back and forth with the moving block, thereby repeatedly shifting the material, and at the same time, the fan above is used to make the cold air in the inner cavity of the cooling box move quickly, which is convenient for the contact between the cold air and the material and accelerates the cooling efficiency of the material. However, the cooling device in the above document only cools the molecular sieve through the cooling box, and does not pre-cool the molecular sieve, so that rapid cooling cannot be achieved when the molecular sieve is cooled. At the same time, the above document realizes the cooling of the molecular sieve by shifting the molecular sieve left and right. The molecular sieve is accumulated inside the barrel, and the cooling effect of the molecular sieve at the thicker accumulation position is poor. When the molecular sieve is cooled, it is not convenient to cool the molecular sieve evenly. Utility Model Content
