Description

Abdichtung für umlaufende Trockentrommeln und Drehöfen Die Erfindung betrifft eine Abdichtung für umlaufende Trockentrommeln und Drehöfen, bei denen die Heizgase quer zur Längsrichtung mittels Düsen durch in das Innere der Trommel eingeführt werden. Das Neue ist darin zu sehen, daß ober- und unterhalb des Düsenraumes zusätzlich Abdichtungskammern angeordnet sind, in welche Gase von niedriger Temperatur unter einem den Druck der Trockengase übersteigenden Druck eingeführt werden.Sealing for rotating drying drums and rotary kilns The invention relates to a seal for rotating drying drums and rotary kilns in which the heating gases transversely to the longitudinal direction by means of nozzles through into the interior of the drum to be introduced. What is new can be seen in the fact that above and below the nozzle space additionally sealing chambers are arranged, in which gases of low temperature be introduced under a pressure exceeding the pressure of the drying gases.

Es ist zwar bei umlaufenden Trockenvorrichtungen bekannt, Luft oder Gas unter Druck an den Abdichtungsstellen einzuführen, um den Austritt von Trockengasen zu verhindern; doch ist diese Maßnahme bisher nur bei solchen Trockentrommeln zur Anwendung gekommen, bei denen das Trockenmittel an der Stirnseite eintritt.Although it is known in rotating drying devices, air or Introduce gas under pressure at the sealing points to prevent the escape of dry gases to prevent; but this measure has so far only been used for such drying drums Used where the desiccant enters at the front.

Die Trockentrommel nach der Erfindung ermöglicht eine bessere Durchtrocknung, da die Trockengase durch das Trockengut durchgepreßt werden. Hierdurch wird auch vermieden, daß Teile des Trocl-"engutes zu hohen Temperaturen ausgesetzt werden. Dies wird auch gemäß der Erfindung noch dadurch verhindert, daß ein Teil der zur Abdichtung verwendeten Gase in die Trockentrommel eingeführt wird und zur Kühlung des Gutes Verwendung findet.The drying drum according to the invention enables better through-drying, because the drying gases are forced through the dry material. This will also avoided that parts of the Trocl- "engutes are exposed to high temperatures. This is also prevented according to the invention in that part of the for Sealing gases used are introduced into the drying drum and used for cooling the good is used.

hei der Trockenvorrichtung gemäß der Erfindung sind sowohl der Drehofen oder die Drehtrommel als auch die Gaszuführungsräume aus Flächenstücken, unten Anliegeflächen genannt, gebildet, die, gegeneinandergestellt, den ob@enerwähnten Dichtungsspalt bilden, der somit zwischen einer gleitenden und einer festen Fläche liegt. Das für das Aufrechterhalten der Abdichtung erforderliche Gas oder die Luft wird in den Spalt durch Öffnungen hineingeführt, die in die Anliegeflächen der Gaszüleitungsräumie ausmünden und den Dichtungsspalt mit einer geeigneten. die Gase bzw. die Luft verdichtenden und hervortreibenden Einrichtung verbinden.in the drying apparatus according to the invention are both the rotary kiln or the rotating drum as well as the gas supply spaces made of flat pieces, with contact surfaces below called, formed, which, placed against each other, the sealing gap mentioned above form, which is thus between a sliding and a fixed surface. That for maintaining the seal required gas or air is in the Gap led into it through openings in the contact surfaces of the gas supply line space open out and the sealing gap with a suitable. the gases or the air compressing and connecting facility.

Eine Trockenvorrichtung gemäß der Erfindung ist in der Zeichnung dargestellt.A drying device according to the invention is shown in the drawing.

Abb. i zeigt einen Querschnitt durch die Trockentrommel. Abb. 2 zeigt den Querschnitt einer abgeänderten Ausführungsform. Abb.3 zeigt einen Längsschnitt durch die in Abb. i dargestellte Trockentrommel. Gemäß Abb. i und 3 sind an der durchbrochenen Trockentrommel i mittels Flügel 3 Anliegeflächen q. angeordnet, zwischen welchen längs verlaufende Spaltöffnungen 7 für den Eintritt des Trockengases in die Trommel vorgesehen sind. Der Gaszuleitungsraum bzw. Gebläsekasten 8 ist um seine öffnung zur Trommel herum mit Anliegeflächen 9 versehen, die sich der Trommel anschmiegen. Die Flächen 9 sind von Löchern io durchbrochen, die den Dichtungsspalt i i mit einem den Gebläsekasten 8 umgebenden Gaskanal 12 verbinden, der seinerseits mit einem Gasverdichter in Verbindung steht. Die Trockentrommel ist mit Hilfe der Rollenringe i q. gelagert.Fig. I shows a cross section through the drying drum. Fig. 2 shows the cross section of a modified embodiment. Fig.3 shows a longitudinal section by the drying drum shown in Fig. i. According to Fig. I and 3 are at the perforated drying drum i by means of wings 3 contact surfaces q. arranged between which longitudinal stomata 7 for the entry of the drying gas into the drum are provided. The gas supply space or blower box 8 is around his The opening to the drum is provided with contact surfaces 9 that nestle against the drum. The surfaces 9 are pierced by holes io that the sealing gap i i with a connect the blower box 8 surrounding gas duct 12, who in turn is in communication with a gas compressor. The drying drum is with the help of the Roller rings i q. stored.

Gemäß Abb. a wird der Trommelmantel anstatt der Durchbrechungen aus gebogenen Blechen 16 gebildet, zwischen welchen Spaltöffnungen 17 für den Eintritt des Gases in die Beschickung vorgesehen sind. Die Anliegeflächen q. sind ähnlich wie in Abb. i angeordnet.According to Fig. A, the drum shell is made from instead of the perforations bent sheets 16 formed, between which gap openings 17 for entry of the gas are provided in the feed. The contact surfaces q. are similar arranged as in Fig. i.

Die Vorrichtung arbeitet in folgender Weise. Die Trockentrommel dreht sich in Uhrzeigerrichtung, wobei sich die Spaltöffnungen 7 der Reihenfolge nach an der Öffnung des Gebläsekastens 8 vorbeibewegen. Das Trockengas wird in den Gebläsekasten unter genügendem Druck eingeführt, um den Widerstand der Beschickung zu überwinden, strömt durch die Spaltöffnungen 7, den Hohlraum a und die durchbrochene Trommel i und dringt in die Beschickung ein, wonach es durch den oberen Teil der Trockentrommel entweicht. Die Ausströmung des Gases durch den Spalt wird dadurch verhindert, daß ein geeignetes Gas, z. B. atmosphärische Luft, vom Kanal i z durch die Löcher io in den Spalt in genügender Menge eingeführt wird, um eine zuverlässige Abdichtung zwischen der Trommel und dem Gebläsekasben zu erreichen.The device works in the following way. The drying drum rotates clockwise, with the stomata 7 in the order Move past the opening of the blower box 8. The drying gas is in the blower box introduced under sufficient pressure to overcome the loading resistance, flows through the gap openings 7, the cavity a and the perforated drum i and penetrates the load, after which it passes through the top of the drying drum escapes. The outflow of the gas through the gap is prevented in that a suitable gas, e.g. B. atmospheric air, from the channel i z through the holes io is introduced into the gap in sufficient quantity to ensure a reliable seal between the drum and the blower box.
