Cyclone with rotating rod basket

A cyclone air separator for separating granular material which is intended to be separated and which is suspended in a conveying gas, comprising

• a first, cylindrical hollow member with a cylindrical form and which has a tangential to helical inlet with respect to the cylindrical form for the conveying gas which carries the material to be separated,
• a second, conical hollow member which is located under the first, cylindrical hollow member and which is connected directly to the first, cylindrical hollow member, wherein a tapered tip of the second, conical hollow member is directed downward,
• at least one immersion pipe which extends through a conical wall of the second, conical hollow member and which projects upward inside the second, conical hollow member and an opening of which is arranged in a volume of the first, cylindrical hollow member,
• wherein, the downwardly directed, tapered tip of the second, conical hollow member is connected to an outlet for fine material,
• wherein a rotating rod basket which
• is surrounded by a static and circular conveying channel which abuts but does not touch a lower external circumference for coarse material is arranged in the first, cylindrical hollow member, wherein the conveying channel for coarse material is connected to an outlet out of the first, cylindrical hollow member, and
• the volume which is surrounded by the rod basket is connected in terms of flow to the second, conical hollow member,
• wherein a conical member, whose tapered tip is directed upward, is arranged above the opening of the immersion pipe, wherein helically formed guiding plates whose winding direction corresponds to a rotation direction of the rod basket are provided on an external surface of the substantially conical member, and,
• wherein the conical member is connected to the rod basket via a shaft and also rotates with the rod basket.
