Description

Satzweise beschickter Schachttrockner Die Erfindung betrifft einen satzweise beschickten Schachttrockner, der aus einem oberen Rieselkaskadenraum und einem darunterhegenden Siloraum und einer lotrecht zentral durch beide Räume geführten Förderschnecke besteht. Die Förderschnecke ist von einem zylindrischen Mantel umgeben, der unten mit einem Ringschieber ausgerüstet ist, mit dem der Schneckenraum wahlweise mit einer Gutaufgabevorrichtung oder mit dem Siloraum in Verbindung gebracht werden kann und der oben einen weiteren Ringschieber aufweist, durch den der Schneckenraum wahlweise mit dem Rieselkaskadenraum oder mit einer Gutablaufvorrichtung in Verbindung gebracht werden kann.Chute dryer loaded in batches The invention relates to a stacked stack dryer, which consists of an upper cascade room and a silo room below and one that runs vertically through both rooms There is a screw conveyor. The screw conveyor is surrounded by a cylindrical jacket, which is equipped with a ring slide at the bottom, with which the screw chamber is optionally available be brought into connection with a material feed device or with the silo space can and which has a further ring slide at the top through which the screw space optionally in connection with the trickle cascade room or with a material drainage device can be brought.

In derartigen Trocknern wird das Gut zunächst mit Warmluft und anschließend zur Kühlung mit Kaltluft behandelt.In such dryers, the material is first heated with warm air and then treated with cold air for cooling.

Der Erfindung liegt die Aufgabe zugrunde, die Luftführung in der Weise zu verbessern, daß durch ein einziges Gebläse die Luft durch den Siloraum und den Rieselkaskadenraum gefördert wird, wobei die Abluft aus dem Siloraum unter Umgehung des Kaskadenraumes abgezogen werden kann und dem Kaskadenraum unausgenutzt frische Behandlungsluft zugeführt werden kann.The invention is based on the object of the air duct in the way to improve that the air through the silo space and the Trickle cascade room is promoted, with the exhaust air from the silo room bypassing the cascade room can be withdrawn and the cascade room unused fresh Treatment air can be supplied.

Das wird erfindungsgemäß dadurch erreicht, daß der Trockner im Bereich des Siloraumbodens einen äußeren ringförmigen Trocknungsmittelzuführungsraum besitzt, der nach oben hin durch eine Ringlochplatte abgedeckt ist und an den ein sternförmiges System flacher Rohre als Wärmetauscher angeschlossen ist. Der Innenraum dieses Wärmetauschers ist mit dem Zwischenraum zwischen einem mit Abstand um den Schneckenraummantel gelegten Siebzylinder und dem Schneckenraummantel im Siloraum verbunden. Weiterhin ist im Kaskadenraum ein ungelochter Zylinder mit Abstand um den Schneckenraummantel gelegt. Dieser Zylinder weist Trocknungsmittelzuführungsschlitze im Bereich der Gutdurchtrittsstellen zwischen Ringkegelplatten und Ringtrichterplatten auf. Weiterhin ist ein zylindrischer Brüdenabführungsraum für den Siloraum konzentrisch um den Rieselschachtraum herumgelegt. Dieser BrüdenabführungSraum weist an seinem oberen Ende eine ringförmige Luftdurchtrittsöffnung in den oberen Bereich des Rieselschachtraums und damit zugleich zum Absaugstutzen des einzigen gemeinsamen Ventilators für Siloraum und Rieselschachtraum auf.This is achieved according to the invention that the dryer in the area the bottom of the silo has an outer annular desiccant supply space, which is covered at the top by an annular perforated plate and to which a star-shaped System of flat tubes is connected as a heat exchanger. The interior of this heat exchanger is placed with the space between a spaced around the worm casing The screen cylinder and the screw casing in the silo are connected. Furthermore, in the Cascade space an unperforated cylinder placed around the worm casing with a gap. This cylinder has drying agent feed slots in the area of the material passage points between ring cone plates and ring funnel plates. Furthermore, it is a cylindrical one Vapor discharge space for the silo space is placed concentrically around the sewer shaft space. This vapor discharge space has an annular air passage opening at its upper end in the upper area of the chimney and thus at the same time to the suction nozzle of the only common fan for the silo room and the sewer chamber.

Die Zeichnung zeigt eine Ausführungsform des neuen Trockners, in Fig. 1 im lotrechten Querschnitt und in Fig. 2 im waagerechten Querschnitt im Bereich der Gutaufgabestelle des Siloraums.The drawing shows an embodiment of the new dryer, in Fig. 1 in vertical cross section and in Fig. 2 in horizontal cross section in the area the feed point of the silo area.

Innerhalb des Trocknermantels A befindet sich der Siloraum b und der Ringkaskadenraum a. Zentral im Trockner liegt die Förderschnecke c im Schneckenraummantel p, der an seinem unteren Ende den Rin-Schieber s, an seinem oberen Ende den Ringschieber r aufweist. Durch Betätigung dieser Schieber ist es in bekannter Weise möglich, das Gut aufzugeben, durch die Räume umzuwälzen und das Gut durch das Ablaufrohr i auszutragen. Der Rieselschachtraum ist mit Ringkegelplatten n und Ringtrichterplatten m ausgerüstet. Die Ringkegelplatten n und weitere Ringkegelplatten l sind an einem ungelochten Zylinder q angebracht. Durch die Zwischenräume zwischen den Platten n und l wird das Behandlungsmittel düsenartig durch die herabrieselnde Gutschicht geblasen, wobei es auch dem Gut anhaftende Beimengungen mitnehmen kann. Um den Rieselschachtraum a herum ist der Brüdenabführungsraum o für den Siloraum gelegt, der in Verbindung mit dem Ansaugstutzen h des Gebläses C steht. Die Heißluft wird aus dem Wärmetauscher B über den Zuluftstutzen g in den Trocknungsmittelzuführungsraum d geführt. Aus diesem tritt ein Teil derselben durch die den Raum d abdeckende Ringlochplatte unmittelbar in die Gutschicht im Siloraum. Ein anderer Teil durchstreicht die Wärmetauscher e und gelangt durch den Zwischenraum zwischen Mantel p und Siebzylinder f mit oberem, ungelochtem Teil bzw. Zylinder q bis zu den zwischen den Platten l und n gebildeten Düsen.Inside the dryer jacket A is the silo space b and the ring cascade space a. Centrally in the dryer is the screw conveyor c in the screw casing p, which has the Rin slide s at its lower end and the ring slide r at its upper end. By operating this slide it is possible in a known manner to abandon the material, to circulate it through the rooms and to discharge the material through the drain pipe i. The trickle chamber is equipped with circular cone plates n and ring funnel plates m . The annular cone plates n and further annular cone plates l are attached to an unperforated cylinder q . Through the spaces between the plates n and l, the treatment agent is blown in a nozzle-like manner through the layer of material that is trickling down, whereby it can also take along additions adhering to the material. The vapor discharge space o for the silo space, which is connected to the suction nozzle h of the fan C, is placed around the trickle duct space a. The hot air is fed from the heat exchanger B via the supply air connection g into the drying agent supply space d. From this a part of the same passes through the annular perforated plate covering the space d directly into the material layer in the silo space. Another part passes through the heat exchanger e and passes through the space between the jacket p and the screen cylinder f with the upper, unperforated part or cylinder q to the nozzles formed between the plates l and n.
