KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine zum Trocknen von beliebigen Stoffen dienende Vorrichtung, bei der das Trockengut zwischen ein beheiztes Band und eine das Band tragende beheizte Walze geführt wird. Vorrichtungen dieser Art vereinigen bekanntlich die Vorteile der Walzentrockner mit denen der Bandtrockner. The invention relates to a device used for drying any materials, in which the material to be dried is heated between a heated belt and a belt carrying the belt Roller is guided. Devices of this type are known to combine the advantages the drum dryer with those of the belt dryer.
Gemäß der Erfindung soll nun eine solche ίο Trockenvorrichtung dadurch verbessert werden, daß das Band einen inneren Hohlraum erhält, in welchem ein beliebiger Wärmeträger untergebracht wird, um eine größere Wärmemenge für den Trocknungsvorgang zur Verfügung zu haben.According to the invention, such a drying device should now be improved by that the band receives an inner cavity in which any heat carrier is housed in order to make a larger amount of heat available for the drying process to have.
Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise schematisch dargestellt, und zwar zeigt:The subject of the invention is shown schematically in the drawing, for example, namely shows:
Fig. ι einen Längsschnitt durch zwei Walzen, welche ein Hohlband tragen,Fig. Ι a longitudinal section through two rollers which carry a hollow belt,
Fig. 2 einen Querschnitt durch das Band für sich.Fig. 2 is a cross section through the tape by itself.
α ist die Trockenwalze, die durch Dampf α is the drying roller driven by steam
oder in anderer Weise beheizt wird, b entweder eine zweite Trockenwalze oder eine lediglich zum Tragen des Bandes c, d dienende Trommel. Das Band besteht aus zwei Teilen, einem oder mehreren vollen Streifen c, die zur Aufnahme des Zuges dienen, und dem eigentlichen gewellten Hohlband d, welches den Wärmeträger — Wasser, öl, Salzlösung, Dampf usw. ·— enthält.or heated in some other way, b either a second drying roller or a drum serving only to carry the belt c, d. The band consists of two parts, one or more full strips c, which serve to accommodate the train, and the actual corrugated hollow band d, which contains the heat transfer medium - water, oil, salt solution, steam, etc. · -.
Das gewellte Hohlband d wird an einer beliebigen Stelle ■— z. B. zwischen den Walzen a, b oder durch die Walze b ■— und in irgendeiner geeigneten Weise beheizt und nimmt infolge des in ihm enthaltenen Stoffes eine verhältnismäßig große Menge Wärme auf. Das Band kann mit derselben Geschwindigkeit wie die Trockenwalze oder auch schneller oder langsamer als diese bewegt werden, auch kann man die Anordnung so treffen, daß das Band allein sich bewegt, in welchem Falle die stillstehende Walze durch eine gerade oder gewölbte Fläche ersetzt werden kann.The corrugated hollow belt d is at any point ■ - z. B. between the rollers a, b or through the roller b ■ - and heated in any suitable manner and absorbs a relatively large amount of heat due to the substance contained in it. The belt can be moved at the same speed as the drying roller or else faster or slower than this, and the arrangement can be made so that the belt moves alone, in which case the stationary roller can be replaced by a straight or curved surface.
Die Beschickung geschieht zweckmäßig auf der Innenseite des Hohlbandes d mittels eines Trichters e o. dgl., kann aber auch an jeder anderen Stelle erfolgen, die sich als zweckmäßig erweist.The charging takes place expediently on the inside of the hollow belt d by means of a funnel e or the like, but can also take place at any other point that proves to be expedient.
