VORTEX FINDER FOR A CYCLONIC SEPARATOR

A vortex finder (F) for a cyclonic separator, the vortex finder comprising a plurality of stationary vanes (V) around which incoming air (A) is guided into the vortex finder (F), in which a side of the vanes (V) facing the incoming air (A) is provided with a protrusion (P) at a stagnation point (S)....

Beschreibung
Zusammenfassung:	A vortex finder (F) for a cyclonic separator, the vortex finder comprising a plurality of stationary vanes (V) around which incoming air (A) is guided into the vortex finder (F), in which a side of the vanes (V) facing the incoming air (A) is provided with a protrusion (P) at a stagnation point (S). The protrusion (P) may be shaped so as to guide the incoming air (A) into the vortex finder (F), and may have a concave side following a shape of a neighboring vane, and a rounded top. Preferably, the protrusion (P) has a height in a range between 70% and 130%, and more preferably in a range between 85% and 115%, of a gap width between the vanes (V). Preferably, a gap width between adjacent vanes (V) increases from an outside to an inside of the vortex finder (F). A vacuum cleaner comprising a cyclonic separator preferably has such a vortex finder (F).
