Description
Vorrichtung zum Entfernen des an der Innenwand von umlaufenden Trommeln infolge der Fliehkraft niedergeschlagenen Staubes Die Erfindung betrifft eine Vorrichtung zum Entfernen des an der Innenwand von umlaufenden Trommeln infolge der Fliehkraft niedergesclllagenen Staubes. Um ein Wiederaufwirbeln dieses Staubes zu verhiiten und ihn ruhig und sicher abzuführen, ist nach der Erfindung ein aus mehreren kammartig nebeneinander angeordneten Kreisausschnitten aus einer Schraubenfläche bestehender und die Abstrcichflächen bildender, im Innern der Trommel ortsfest angebrachter und bis in die Nähe der Trommelwand heranreichender Abstreicher vorgesehen, wobei es vorteilhaft ist, wenn die Abstreichflächen an der axial sich in das Innere der Trommel erstreckenden Zuleitung für das Rohgas befestigt sind.Device for removing the on the inner wall of rotating drums due to the centrifugal force deposited dust The invention relates to a device for removing the on the inner wall of rotating drums as a result of centrifugal force downed dust. To prevent this dust from being stirred up again and to dissipate it calmly and safely, according to the invention, is one of several comb-like Circular segments arranged next to one another from a helical surface of existing ones and those forming the swab areas, fixedly mounted inside the drum and scrapers reaching up to the vicinity of the drum wall are provided, wherein It is advantageous if the wiping surfaces on the axially into the interior of the Drum extending feed line for the raw gas are attached.
Die Zeichnung stellt schematisch ein Ausführungsbeispiel der Erfindung in Längs- und Querschnitt dar. The drawing shows schematically an embodiment of the invention in longitudinal and cross-section.
Der staubhaltige Rohgasstrom wird durch die Leitung 10 eingeblasen, so daß sich der Staub an der schnell umlaufenden Trommel 1 1 als ausgebreitete Schicht fest anlegt. The dusty raw gas stream is blown in through line 10, so that the dust on the rapidly rotating drum 11 as a spread layer firmly applied.
Durch den Trommelumlauf gelangt diese Schicht alsbald an die Streichmesser I2, welche in größerer Zahl nebeneinander an der Leitung IO angeordnet sind. Sie reichen bis dicht an die Trommelwand, und ihre Flächen sind ein wenig schraubenförmig gekrümmt, also gegen die Trommelachse verdreht. Beim Umlauf der Trommel im Sinne des Pfeiles x verschieben sie daher jedes Teilchen der an der Trommelwand haftenden Schicht bei jeder Umdrehung ein wenig gegen das offene Ende der Trommel hin, um stets Platz für frisch sich niedersetzenden Staub zu machen.As the drum rotates, this layer soon reaches the doctor blades I2, which are arranged in large numbers next to one another on the line IO. she reach close to the drum wall, and their surfaces are a little helical curved, i.e. twisted against the drum axis. When rotating the drum in the sense of the arrow x, they move every particle that adheres to the drum wall Shift a little towards the open end of the drum for each rotation to always make room for freshly settling dust.
Die Verdrehung der Streichmesser I2 ist so bemessen, daß jedes Messerende bis in die vom benachbarten Messer bestrichene Trommelzone reicht, somit die ganze Trommelinnenfläche von den Messern bestrichen wird.The rotation of the doctor knife I2 is measured so that each end of the knife extends into the drum zone swept by the neighboring knife, thus the whole The inside of the drum is brushed by the knives.
Die Rohgaszuleitung IO mündet in etwa radialer Richtung auf die Innenwand der Trommel II, um ein kräftiges Aufblasen des Rohgases auf diese zu bewirken; die im Umlaufsinn der Trommel hintere Wand läuft hingegen in die Schmiege 13 aus, die etwa gleichachsig mit der Trommelwandung gekrümmt ist und hierdurch ein wirbelfreies Anlegen des Rohgasstromes an die Wand herbeiführt. The raw gas feed line IO opens in an approximately radial direction onto the inner wall the drum II to cause the raw gas to be vigorously inflated thereon; the in the direction of rotation of the drum rear wall, however, runs into the bevel 13, which is curved approximately coaxially with the drum wall and thereby a vortex-free Creates the raw gas flow on the wall.
Der aus der Trommel hinausgeschobene Staub gleitet auf der geneigten Sohle r der die Trommelmündung umschließenden ortsfesten Haube 15 hinunter, um sich über dem Schieber I6 zu sammeln, nach dessen oeffnung er nach Bedarf entnommen werden kann. The dust pushed out of the drum slides on the inclined one Sole r of the stationary hood 15 surrounding the drum mouth down to itself to collect via the slide I6, after which it can be removed as required can.
Das gereinigte Gas zieht durch die Leitung 17 ab. The cleaned gas is withdrawn through line 17.
