Description

-Fliehkraft — O-Centrifugal force - O

'Bei iriiehkraft-Staubabsctieidem bekanner Bauart Ist am einen Ende einer 'Wirbelkammer ein turbinenradänn— lictier Leitapparat vorgesehen, so daß die hierdurch eintretende Luft einen Wirbel bildet, aus dem unter der Wirkung der Zentrifugalkraft die spezifisch Gchv/ereren Sbaub—Partikelchen ausgeschieden werden. Am Boden der //irbelkammer Ist eine Öffnung vorgesehen,, an die ein Staubsaugekanal anschließt*'With iriiehkraft-Staubabsctieidem known design is at one end of a vortex chamber a turbine wheel lictier distributor provided, so that this incoming air forms a vortex from which under the effect of centrifugal force the specific Gchv / ereren Sbaub particles are excreted. An opening is provided at the bottom of the vortex chamber. to which a vacuum duct connects *

Da das innere der Wirbelkammer unter Unterdruck steht, muß der Staubsaugekanal zur Bewirkung des Absaugens an eine Unterdruckquelle angeschlossen werden» Die zum Abtransport des Staubes nötige Luftmenge soll so klein wie möglich sein, damit der Energiebedarf der Unterdruckquelle möglichst gering bleibt· Praktisch beträgt die Menge der pro Zeiteinheit durchgesetzten Staubtransportluft etwa 4- - 5 % des zu reinigenden Luftdurchsatzes. Da auch die Geschwindigkeit der Staubtransportluft einen bestimmten iSfert - etwa 1p m/sec haben soll, ist der Querschnitt des Staub saugekaiÄs weitgehend festgelegt*Since the inside of the vortex chamber is under negative pressure, the vacuum duct must be used to effect the suction be connected to a vacuum source »The amount of air required to remove the dust should be be as small as possible so that the energy requirement of the vacuum source remains as low as possible · Practical the amount of dust transport air passed through per unit of time is about 4-5% of that to be cleaned Air flow. Since the speed of the dust transport air has a certain iSfert - about 1p m / sec is the cross section of the vacuum cleaner quay largely determined *

Bei den bekannten. Staubabscheidern kommt es nun vor, daß bei plötzlichem groben Stastbarrfall in der zu reinigenden Luft der Querschnitt dass Staub saaigekanals nicht ausreicht unst dieser-With the known. It now happens to dust collectors that in the event of a sudden, coarse lockdown in the one to be cleaned Air the cross-section that dust saaigekanal not enough for this-

Zur Überwindung dieses Nachteils wird erfindungsgemäß vorgeschlagen, in der Wirbelkammer zwei Wirbelsenken zu erzeugen und derart zusammenwirken zu lassen* daß der von ihnen ausgeschiedene Staaife in einem gemeinsamen Staubsaugekanal abgeführt wearden kann·To overcome this disadvantage, according to the invention suggested creating two vertebral sinks in the vortex chamber and allowing them to work together * that the Staaife they left in a common Vacuum duct removed can wearden

Auf diese Weise kann der Querschnitt des Staubsaugekanals auf das doppelte vergrößert werden, ohne daß sich das Verhältnis der iitaubtranspoarfelrafInaenge zur- Durchsat zmenge der zu reinigendem Luft raigünstig erhöht· Als weiterer Vorteil ergibt sich eine Verbesserung des Abscheidungswirkungsgrades·In this way, the cross section of the vacuum cleaner duct can be enlarged to double without it the ratio of the transportable area to the throughput The amount of air to be cleaned is increased Another advantage is an improvement in the separation efficiency

Pig. 1 lind 2 verdeutlicht dieses Prinzip. Die Wirbelkammer 1 trägt an beiden Enden turbinenradähnliche Leitapparate 3 und 2, durch, die die zu reinigende Luft einströmt. Die gereinigte Luft wird durch die Stechrohre 5 und 6 abgesaugt. Zwischen beiden Leitapparaten, etwa in der Mitte der Wirbelkammer mündet tangential der Staubsaugekanal 4-.Pig. 1 and 2 illustrate this principle. The vortex chamber 1 carries turbine-wheel-like diffusers 3 and 2 at both ends, which carry the air to be cleaned flows in. The cleaned air is through the piercing tubes 5 and 6 sucked off. Between the two nozzles Approximately in the middle of the vortex chamber, the vacuum duct 4- opens tangentially.

Im Betrieb bilden sich in der Wirbelkammer zwei '.Virbelsenken aus , wobei jeder Wirbelkern durch das ihm zugeordnete Stechrohr 5 abgezogen wird. Der aus beiden Wirbeln ausgeschiedene Staub sammelt sich in einer gemeinsamen neutralen Zone zwischen beiden Wirbeln. Er ist dort noch mit einem Drehimpuls behaftet, so daß er glatt in den in Höhe der neutralen Zone mündenden Staubsaugekanal 4 einläuft.During operation, two vortex sinks form in the vortex chamber, each vortex core through it associated piercing tube 5 is withdrawn. The dust separated from both eddies collects in a common one neutral zone between both vertebrae. There it is still afflicted with an angular momentum, so that it runs smoothly into the vacuum suction channel 4 opening at the level of the neutral zone.

Es wird auf diese Weise auch die bei Staubabscheidern herkömmlicher Bauart auftretende Reibung des Wirbels am Gehäuseboden vermieden, so daß die Umlaufgeschwindigkeit der in der Wirbelkammer kreisensen-Luftsäule über die -csamte wirbelkammerlänge konstant ist. Daraus ergibt sich der bereits angeführte Vorteil des höheren AbScheidungswirkungsgrades.In this way, the vortex friction that occurs in conventional dust collectors is also eliminated Avoided at the bottom of the case, so that the speed of circulation in the vortex chamber circling air column is constant over the entire length of the vortex chamber. From it this results in the already mentioned advantage of the higher separation efficiency.
