Description
Vorrichtung zum Fördern von Papptafeln und ähnlichem Gut durch Trockner Bekanntlich trocknet ein Trockengut desto schneller, je größer die Geschwindigkeit des es bestreichenden Trockenluftstromes ist. Beim Trocknen von flächigem Gut, beispielsweise Pappen in flach liegendem Zustand auf Fördervorrichtungen, ist man jedoch an eine gewisse ziemlich geringe Höchstgeschwindigkeit des Luftstromes gebunden, weil. bei ihrer Überschreitung die Pappen aus ihrer Lage weggeblasen werden. Um sie zu halten, ist die Anwendung eines Deckbandes erforderlich. Dieses Band darf aber nicht auf dem Trockengut aufliegen, weil es sonst Eindrücke hervorruft, da das Trockengut, solange es naß ist, weich ist.Device for conveying cardboard and similar items through dryers As is well known, the faster a dry product dries, the greater the speed of the dry air stream sweeping it. When drying flat material, for example Cardboard lying flat on conveyors, however, is one certain fairly low top speed of air flow bound because. at if exceeded, the cardboard will be blown away from its position. To hold her the application of a cover tape is required. However, this tape must not open rest on the dry goods, because otherwise it will cause impressions, as the dry goods, as long as it's wet, it's soft.
Die Erfindung betrifft eine Fördervorrichtung für Pappen u. dgl. Gut durch Trockner, bei der das Trockengut auf ein Förderband aufgelegt und durch ein in einem Abstand von diesem Förderband laufendes Deckband auch bei starker Belüftung in seiner Lage gehalten wird.The invention relates to a conveying device for cardboard and the like through dryer, in which the material to be dried is placed on a conveyor belt and through a Cover belt running at a distance from this conveyor belt even with strong ventilation is held in place.
Die Zeichnung veranschaulicht durch Abb. i die Vorrichtung im Schnitt durch den Aufriß eines Trockners und durch Abb. z im Querschnitt durch einen Trockner in schematischer Darstellung. Das Trockengut wird auf einem Förderband u ruhend, durch den Trockenkanal b geführt. In geringem Abstand über dem Trockengut läuft ein zweites Band c, das ein Verwehen des Trockengutes verhindert. Die beiden Bänder, sowohl das Förderband (Tragband) a als auch das zweite Band (Deckband) c, sind an Trägernd, die ihrerseits an ihren Enden von umlaufenden Ketten e getragen werden, befestigt, und zwar gemäß der Erfindung z. B. mittels Stützen/, die die Bänder in einem gewissen Abstand von den Trägern halten, um zu ermöglichen, daß die Trockenluft auch zwischen den Trägern d und den Bändern a und c hindurchstreichen kann. Zweck dieser Maßnahme ist, zu verhindern, daß durch Luftschatten auf dem Trockengut Wellen oder Verfärbungen entstehen. Würden die Bänder a und c unmittelbar an den Trägern d ohne Wahrung eines Abstandes befestigt, so würde das Trokkengut oberhalb und unterhalb der Träger d infolge geringerer Belüftung als an anderen Stellen von diesen sogenannten Luftschatten beeinfl ußt.The drawing illustrates by Fig. I the device in section through the elevation of a dryer and by Fig. Z in cross section through a dryer in a schematic representation. The material to be dried is guided through the drying channel b, resting on a conveyor belt u. A second belt c runs a short distance above the dry goods and prevents the dry goods from being blown away. The two belts, both the conveyor belt (carrier belt) a and the second belt (cover belt) c, are attached to carriers, which in turn are supported at their ends by revolving chains e. B. by means of supports /, which hold the belts at a certain distance from the carriers, in order to enable the drying air to pass between the carriers d and the belts a and c. The purpose of this measure is to prevent air shadows from causing waves or discoloration on the dry material. If the straps a and c were attached directly to the supports d without maintaining a distance, the dry material above and below the support d would be influenced by these so-called air shadows as a result of less ventilation than elsewhere.
