Abstract
A powder recycling system includes a powder feeder, a remaining powder collector, a bridge breaker, a block powder filter, a cyclone separator, a particulate filter cleaner, an air pressure generation device and an electrostatic precipitator. The powder feeder provides a construction powder to a construction platform. The remaining powder collector for collects the remaining powder. The cyclone separator is used to separate the large-size powdery particles and the small-size powdery particles of the remaining powder from each other through a rotating gaseous stream. The large-size powdery particles fall down to the powder feeder due to gravity, and the small-size powdery particles of the remaining powder is removed from the rotating gaseous stream and transmitted to the particulate filter cleaner. After the small-size powdery particles of the remaining powder are filtered by the particulate filter cleaner, the suspended small-size powdery particles are transmitted to the electrostatic precipitator.
