Description
Trockenofen mit periodisch angetriebener endloser Förderkette Trockenöfen, welche mit einer Förderkette innerhalb des Ofens versehen sind, um das Trockengut allmählich durch den Ofen zu führen, werden periodisch beschickt und eiltleert. Für den periodischen Antrieb der Kette benutzt man vorzugsweise ein Kurbelgetriebe, welches die Bewegung nach jeder Umdrehung zum Stillstand bringt, so daß eine neue Beschickung vorgenommen werden kann. Während des Beschickungsvorganges muß der Ofen geöffnet werden, um das Gut auf die Tragplatten der Förderkette abzusetzen, wobei der Ofen einen Teil seiner Wärme durch die Aufgabeöffnung abgibt. Um Wärmeverluste zu vermeiden, werden Verschlüsse eingebaut, welche von Hand betätigt werden, aber einen vollkommenen Abschluß nicht geben. Es ist nämlich erforderlich, daß das Glied der Förderkette, welche beschickt werden soll, von den übrigen Gliedern der Kette abgeschlossen wird, -d. h. sich in einer Kammer befindet, welche für die Beschickung nach außen offen bleibt.Drying oven with periodically driven endless conveyor chain drying ovens, which are provided with a conveyor chain inside the oven to carry the dry goods gradually through the furnace are periodically loaded and emptied. A crank gear is preferably used for the periodic drive of the chain, which brings the movement to a standstill after each revolution, so that a new one Loading can be made. During the loading process, the furnace must are opened in order to deposit the goods on the support plates of the conveyor chain, with the furnace gives off part of its heat through the feed opening. About heat loss to avoid, locks are installed, which are operated by hand, but not give a perfect close. Namely, it is necessary that the limb the conveyor chain that is to be fed from the other links of the chain is completed, -d. H. is located in a chamber which is used for loading remains open to the outside world.
Die Erfindung gibt hier eine Neuerung, ,N-elche im wesentlichen darin besteht, daß der periodische Antrieb gleichzeitig zwei Verschlußklappen betätigt, welche während des Stillstandes der Förderkette eine gegen den Ofen abgeschlossene Kammer um einen Förderbecher bilden, die zur Beschickung nach außen offen bleibt. Da dieser Verschluß von dem Kettenantrieb betätigt wird, wird er stets in Übereinstimmung . mit dem Kettengang arbeiten.The invention gives a novelty here, N-elche essentially therein consists that the periodic drive actuates two flaps at the same time, which during the standstill of the conveyor chain a closed against the furnace Form a chamber around a conveyor cup that remains open to the outside for loading. Since this lock is operated by the chain drive, it is always in accordance . work with the chain gear.
Der Gegenstand gemäß der Erfindung soll an Hand der schematischen Zeichnung näher erläutert werden.The object according to the invention is to be based on the schematic Drawing will be explained in more detail.
Eine Förderkette a wird durch die Stange b vermittels der Kurbel c um den Kurbelhub hochgezogen. Die Kurbel wird durch die Welle d angetrieben. Die Welle d wird in bekannter Weise gesteuert, wobei die Kurbel c nur immer eine Umdrehung macht und sich dann selbst auslöst. Der Kurbelweg e ist also gleich der Bewegung f der Kette. Die Öffnung g des Ofens h ist durch die Schieber i, k in der Weise abgeschlossen, daß diese gegen die Platte L stoßen. Die beiden Schieber werden durch die Stangen in und n sowie den Nocken o vermittels der Stange p betätigt.A conveyor chain a is pulled up by the crank stroke by the rod b by means of the crank c. The crank is driven by the shaft d . The shaft d is controlled in a known manner, the crank c only making one revolution and then tripping itself. The crank travel e is therefore equal to the movement f of the chain. The opening g of the furnace h is closed off by the slides i, k in such a way that these push against the plate L. The two slides are actuated by the rods in and n and the cam o by means of the rod p.
Der Vorgang ist folgender: Wird die Welle d eingerückt, so bewegt sich die Stange b entsprechend der Kurbel c und nimmt die Kette um den Kurbelhub e mit. Der Nocken o ist so gestellt, daß er durch den Hebel p vorher die Klappen i. und k in die punktierte Lage gebracht hat. Jetzt kann der Becher r ungehindert nach oben weitergehen. Durch die Freigabe des Nockens o werden die Klappen i und k vermittels der Feder s wieder geschlossen und bilden eine Kammer um den Becher. Es ist hierbei gleichgültig, ob der Verschluß senkrecht oder waagerecht angeordnet ist. Desgleichen kann für die Förderkette ein Förderband verwandt werden.The process is as follows: If the shaft d is engaged, the rod b moves in accordance with the crank c and takes the chain with it by the crank stroke e. The cam o is set so that it previously opened the flaps i by the lever p. and brought k to the dotted position. Now the cup r can move upwards unhindered. When the cam o is released, the flaps i and k are closed again by means of the spring s and form a chamber around the cup. It does not matter whether the closure is arranged vertically or horizontally. A conveyor belt can also be used for the conveyor chain.
