CLASSIFIER THAT IS CONFIGURED FILTRATION FAN

摘要

A classifier (100) having filtration fans according to the present invention comprises: an external chamber (110) formed to make powdered material flow in and connected to a discharge pipe (160); an internal chamber (120) housed within the external chamber (110) and connected to the discharge pipe (160); an inflow pipe (130) formed to be connected to the side of the internal chamber (120); and the filtration fans (140) installed at ends (137) of the inflow pipe (130) separated from each other while facing each other and filtering powdered particles. Thus, the present invention filters thick particles via an air membrane formed via the filtration fans (140) and fine particles pass through the air membrane while rotating with blades (143) of the filtration fans (140). In addition, the classifier of the present invention basically prevents the phenomenon that powder flows into a gap between the blade (143) and the inflow pipe (130), thereby being capable of efficiently selecting the fine powder with a size of 0.7-10 μm from the powdered material.
