Abstract

Ein Zyklonabscheider mit einem oben abgedeckt geschlossenen Zyklongehäuse (1) und mit einem Zufuhrkanal (11) für die Zufuhr der belasteten Luft weist die Form eines kopfstehenden, unten offenen Kegelstumpfes auf. Konzentrisch ist von oben ein Tauchrohr (12) in die Abdeckung (14) eingelassen. Es reicht teilweise in das Zyklongehäuse (1) hinein. Vom Tauchrohr (12) führt ein Abluftkanal weg, beispielsweise zu einem Reinluftfilter. An das unten offene Zyklongehäuse (1) schliesst ein Auffangkonus (3) an, welcher wie ein Trichter das abgeschiedene Material sammelt und abwärts in einen Sammelbehälter (4) leitet. Eine besondere Ausgestaltung des Tauchrohres (12) vermindert ein Ablagern von ausgeschiedenem Material an diesem selbst. Zusätzlich kann Reinigungsluft (RL) in den Bereich des Tauchrohres (12) gezielt eingeblasen werden.

Figure 00000001
A cyclone separator with a closed cyclone housing (1) covered at the top and with a supply channel (11) for supplying the polluted air has the shape of an inverted truncated cone which is open at the bottom. An immersion tube (12) is let into the cover (14) concentrically from above. It partially extends into the cyclone housing (1). An exhaust air duct leads away from the immersion pipe (12), for example to a clean air filter. A collecting cone (3) connects to the cyclone housing (1), which collects the separated material like a funnel and directs it downwards into a collecting container (4). A special design of the immersion tube (12) reduces the deposition of the deposited material on it itself. In addition, cleaning air (RL) can be blown into the area of the immersion tube (12) in a targeted manner.
