Description

Technical Field

[0002] A fine powder classification device is a device used to separate and classify fine powder materials according to particle size or other characteristics.

[0003] The working principle of the existing powder separator is to bring all the materials to be screened to the classification area of the dynamic powder separator, and realize the separation of thick and thin materials by static blades and adjusting the rotation speed of the rotating part. This increases the load and circulating load of the dynamic powder separator, increases the installed power of the powder separator accordingly, results in an increase in the power consumption of the powder separator, and improves the operating cost.

[0004] The existing patent (Publication No.: CN221046641U) relates to an integrated powder separator for coarse powder separation and fine powder classification, belonging to the technical field of powder screening equipment, including a coarse powder separation part and a fine powder classification part. The coarse powder separation part is located below the fine powder classification part; the coarse powder separation part has no power source, and an adjustable deflector is provided inside it; a rotating part is provided inside the fine powder classification part, and static blades are provided outside the rotating part. By adjusting the angle of the static blades and the rotation speed of the rotating part, the medium and coarse powder of the materials can be separated; in the present invention, the coarse powder that does not meet the requirements is preferentially screened out in the coarse powder separation part, so that it no longer enters the fine powder classification part, effectively reducing the load and circulating load of the fine powder classification part; the coarse powder separation part itself has no power, which can effectively reduce the overall power consumption; the fine powder classification part realizes the classification adjustment of particle fineness by adjusting the angle of the static blades and the rotation speed of the rotating part, the collected particle size range is adjustable, the powder selection efficiency is high, and the resistance loss and energy consumption are low.

[0005] In view of the above problems, the existing patent gives a solution. There are certain limitations in the above solution during use. The performance of the existing fine powder classification device is greatly affected by material characteristics such as humidity. When the material humidity is high or the materials are sticky to each other, the particles are prone to agglomeration, resulting in a poor classification effect.
