Description

분체분급기Powder classifier

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1 도는 본 발명에 따른 분체분급기를 이용한 분급실험결과로부터 구해진 입도분포도.1 is a particle size distribution diagram obtained from the classification test results using the powder classifier according to the present invention.

제 2 도는 분체분급기의 일예의 종단면도.2 is a longitudinal sectional view of an example of a powder classifier.

제 3 도는 상기 분급기의 부분절결평면도.3 is a partially cutaway plan view of the classifier.

Claims (1)

상면 중앙에 분체 주입구를 갖고 외측벽 주위에 공기 도입구를 갖는 케이싱내에 주연부로부터 축심방향을 향해 연장하도록 배치된 복수의 분급날개에 의해 공기유통 공동부가 형성된 분급로우터를 수직회전축에 의해 회전가능하게 설치하고, 상기 분급로우터의 회전에 의해 분체에 작용하는 원심력관 상기 공기 유통 공동부를 축심방향으로 통과하는 공기류에 의해 상기 분체에 작용하는 항력과의 평형에 의해 분체를 분급하는 분체분급기에 있어서,In the casing having a powder inlet in the center of the upper surface and an air inlet around the outer wall, a classifying rotor formed by a plurality of classifying vanes arranged so as to extend from the periphery toward the axial direction is rotatably installed by a vertical rotating shaft. In the powder classifier which classifies the powder by equilibrium with the drag force acting on the powder by the air flow passing through the air distribution cavity in the axial direction, the centrifugal force tube acting on the powder by the rotation of the classification rotor, 상기 분급날개의 매수를, 적어도 분급로우터의 직경과 상기 공기유통 공동부를 통과하는 공기량에 의거하여 통상 정해지는 분급날개의 매수보다 적은 매수로 한 것을 특징으로 하는 분체분급기.And the number of sheets of the classifying blade is less than the number of classifying blades normally determined based on at least the diameter of the classifying rotor and the amount of air passing through the air flow cavity. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
