Description
Trommeltrockner mit Einrichtung zur Kühlung des Gutes an der Austrittsstelle Es sind Kühleinrichtungen im unmittelbaren Anschluß an Trockentrommeln oder deren Luftauslaßteil bekannt, bei denen durch das die Kühltrommel gleichachsig umschließende Ausfallgehäuse ein Ringraum gebildet wird, durch den das austretende Gut mit Hilfe von Förderschaufeln unter Einwirkung eines Kühlluftstromes einem Sammelgehäuse zugeführt wird.Drum dryer with device for cooling the goods at the exit point There are cooling devices in the immediate vicinity of drying drums or their Air outlet part known, in which by the coaxially enclosing the cooling drum Failure housing an annular space is formed through which the escaping material with the help fed by conveyor blades under the action of a cooling air flow to a collecting housing will.
Diese Einrichtungen haben den Nachteil, daß hierbei rein großer Teil der Kühlluft unausgenutzt durch den Ringraum zieht, da nur der untere Teil desselben mit dem zu kühlenden Gut gefüllt ist. Außerdem verursachen die den Rücktransport bewirkenden Förderschaufeln eine Zerkleinerung des Trockengutes, die unerwünscht sein kann.These facilities have the disadvantage that this is a purely large part the cooling air draws unused through the annulus, as only the lower part of it is filled with the goods to be cooled. They also cause the return transport causing the conveyor blades to shred the dry material, which is undesirable can be.
Die Erfindung vermeidet diese Nachteile dadurch, daß das Ausfallgehäuse hinter der Kühltrommel mit einem die letztere eng umschließenden Gehäuse an das Luftauslaßgehäuse angeschlossen ist. Ferner ist das hinter der Kühltrommel befindliche Ausfallgehäuse durch .eine Schurre mit dem unter dem Luftausfallgehäuse angeordneten Sammelrumpf verbunden. Die Schurre soll mit jalousieartig übereinander angeordneten Gleit-Rächen versehen sein, zwischen denen Lufteinlaßschlitzeangeordnet sind.The invention avoids these disadvantages in that the failure housing behind the cooling drum with a housing that tightly encloses the latter Air outlet housing is connected. Furthermore, that is located behind the cooling drum Dropout housing by. A chute with the one arranged under the air dropout housing Collective hull connected. The chute should be arranged one above the other in the manner of louvers Be provided sliding rakes, between which air inlet slots are arranged.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.
Abb. i zeigt das Ausfallende einer Trockentrommel in senkrechtem Längsschnitt und Abb. 2 in Ansieht von vorn.Fig. I shows the dropout of a drying drum in a vertical longitudinal section and Fig. 2 viewed from the front.
Abb. 3 zeigt einen Teil der Ausfallvorrichtung in. senkrechtem Querschnitt.Fig. 3 shows part of the failure device in. Vertical cross-section.
An die Trockentrommel i schließt sich in bekannter Weise der Luftauslaßteil2 an. An diesem ist die Kühltrommel 3 gleichachsig zur Trockentrommel i befestigt. Die Kühltrommel ist in bekannter Weise mit Rieselzellen ¢ versehen. Der Luftauslaßteil2 ist von dem Luftauslaßgehäuse 5 umgeben, an das sich das Ausfallgehäuse 6 anschließt, welches die Kühltrommel 3- eng umschließt. Die Kühltrommel 3 ist mit dem Stauring 7 versehen. In' der Seitenwand 8 des Gehäuses 6 sind die Lufteinlaßrohre9 und io'angeordnet. An den unteren Teil des Luftausläßgehäuses.5 schließt sich der Sammelraum r i an, unter dem die Förderschnecke 12 angeordnet ist. Das Gehäuse 6 ist durch die Schurre 13 mit dem Sammelraum i i verbunden, deren Gleitfläche 1 ¢ ,aus jalousieartig übereinander angeordneten Flächen besteht, zwischen denen sich Lufteinlaßschlitze 15 befinden.The air outlet part 2 adjoins the drying drum i in a known manner. On this the cooling drum 3 is attached coaxially to the drying drum i. The cooling drum is provided with trickle cells [in a known manner]. The air outlet part 2 is surrounded by the air outlet housing 5, which is followed by the dropout housing 6, which closely encloses the cooling drum 3-. The cooling drum 3 is provided with the storage ring 7. In ' the side wall 8 of the housing 6, the air inlet pipes 9 and io' are arranged. The collecting space ri, under which the screw conveyor 12 is arranged, adjoins the lower part of the air outlet housing. 5. The housing 6 is connected by the chute 13 to the collecting space ii, the sliding surface 1 [of which consists of surfaces arranged one above the other in the manner of a louvre, between which there are air inlet slots 15.
Das getrocknete Gut wird am Ende der Kühltrommel 3 durch den Stauring 7 angestaut. Die durch die öffnungen 9 und io eintretende Kühlluft durchströmt die Rieselzellen und tritt durch die Luftauslaßschlitze des LuftauslaßteileS 2 in das Luftauslaßgehäuse 5. Da die Kühltrommel g von dem Gehäuse 6 eng umschlossen ist; so wird die gesamte Kühlluft zwangsläufig durch die Kühltrommel geführt. Die Kühlluft streicht über das Gut im Gegenstrom hinweg und wird von dem über dem Sammelgehäuse angeordneten Exhaustor durch die Schlitze des Luftauslasses abgesaugt. Infolge des in der Kühltrommel herrschenden Unterdruckes wird durch die Lufteinlaßschlitze 15 der Schurre 13 zusätzlich Kühlluft eingesäugt, die das durch die Schurre ausfallende Gut nochmals kühlt und dann durch das Luftauslaßgehäuse 5 entweicht.The dried material is at the end of the cooling drum 3 through the storage ring 7 accumulated. The cooling air entering through the openings 9 and io flows through the Flow cells and enters through the air outlet slits of the air outlet part 2 Air outlet housing 5. Since the cooling drum g is closely enclosed by the housing 6; so the entire cooling air is inevitably led through the cooling drum. The cooling air sweeps over the material in countercurrent and is removed from the material above the collecting housing arranged exhaustor sucked through the slots of the air outlet. As a result of the The negative pressure prevailing in the cooling drum is passed through the air inlet slots 15 the chute 13 additionally sucked in cooling air, the falling through the chute Cools well again and then escapes through the air outlet housing 5.
