Beschreibung
Zusammenfassung:	The utility model discloses a device for separating impurities from coal powder, which relates to the conveying of fire coal in a thermal power plant, in particular to the separation of the impurities which are contained in the conveyed fire coal. The device for separating the impurities from coal powder comprises a conveying belt; one end of the conveying belt in a conveying direction is provided with a lower coal bucket, and a sieve body is arranged at the inlet of the upper end of the lower coal bucket. The device for separating the impurities from coal powder has the beneficial effects that: when the coal powder contains large impurities, the impurities are thrown onto the sieve body due to the inertial conveying role of the conveying belt and are intercepted, and the coal powder enters the lower coal bucket.
