Abstract

Die Erfindung betrifft eine Vorrichtung zum Abscheiden von Staub aus staubbeladener Luft, insbesondere zur Verwendung in einem Staubsauger, in Form eines Zyklon-Abscheiders, bei dem die Luft einem wenigstens annähernd rotationssymmetrischen Behälter (11) über einen tangential angeordneten Einlass (12) zugeführt wird und nach dem Durchströmen einer Staubsammelkammer (14) über einen axial angeordneten Auslass abgeführt wird. Eine Vorrichtung zum Abscheiden von Staub aus staubbeladener Luft, welche einerseits auf dem Prinzip des Zyklon-Abscheiders basiert und deshalb eine Verwirbelung der Staubpartikel im Staubsammelbehälter verursacht und bei welcher andererseits die Trenngrenze weit über der Partikelgröße von lungengängigem Feinstaub (weniger als 2 µm) liegt, besitzt einen Behälter (11), der derart ausgebildet ist, dass die Strömungsgeschwindigkeit des Luftstroms im Einströmbereich des Auslasses (3) geringer als im Bereich des Einlasses (12) ist.

Figure imgaf001
The invention relates to a device for separating dust from dust-laden air, in particular for use in a vacuum cleaner, in the form of a cyclone separator, in which the air is supplied to an at least approximately rotationally symmetrical container (11) via a tangentially arranged inlet (12) and is discharged via an axially arranged outlet after flowing through a dust collecting chamber (14). A device for separating dust from dust-laden air, which is based on the one hand on the principle of the cyclone separator and therefore causes a turbulence of the dust particles in the dust collector and in which on the other hand, the separation limit is far beyond the particle size of respirable particulate matter (less than 2 microns), has a container (11) which is formed such that the flow velocity of the air flow in the inflow region of the outlet (3) is less than in the region of the inlet (12).
