Description
Wendevorrichtung für Bandtrockner Der Erfindungsgegenstand gehört zur Klasse der Bandtrockner zum Trocknen von aus kristallbildenden Flüssigkeiten gewonnenem Kristall, insbesondere von Siedesalz im Salinenbetrieb. Solche Bandtrockner weisen in der Bewegungsrichtung des Trocknungsbandes abstandsweise folgende Wendevorrichtungen auf.Turning device for belt dryer The subject of the invention belongs to the class of belt dryers for drying liquids that form crystals extracted crystal, especially from evaporated salt in the salt works. Such belt dryers have the following turning devices at intervals in the direction of movement of the drying belt on.
Es hat sich nun herausgestellt, däß die bekannten umlaufenden Wendevorrichtungen, die schaufelartige Organe als Wender tragen, für die Behandlung von Kristall-, -insbesondere Salzkristallschichten ungeeignet sind. Diese Kristallschichten neigen zum Verziehen der relativ zu ihnen bewegten Wenderflächen, so daß diese sich schnell mit einer fest kristallisierenden Salzschicht bedecken und dann die auf dem Trocknungsband ruhende Kristallschicht und das Band selbst beschädigen bzw. zerstören. Dieser besondere Nachteil hat die Anwendung von Bandtrocknern im Salinenbetrieb bisher erschwert.It has now been found that the known rotating turning devices, carry the shovel-like organs as turner, for the treatment of crystal, -in particular Salt crystal layers are unsuitable. These crystal layers tend to warp of the turning surfaces moved relative to them, so that they move quickly with a Cover the solidly crystallizing salt layer and then place it on the drying belt Damage or destroy the static crystal layer and the tape itself. This particular one The disadvantage has hitherto made the use of belt dryers in salt works more difficult.
Die neue Wendevorrichtung nach der vorliegenden Erfindung verhindert diese Nachteile.The new turning device according to the present invention prevents these disadvantages.
Sie besteht im wesentlichen aus zwischen Stirnscheiben oder Armkreuzen einer umlaufenden Welle achsparallel ausgespannten Stahldrähten, wobei zweckmäßig diese Stahldrähte kreisrunden Querschnitt besitzen und aus nichtrostendem Stahlmaterial hergestellt sind.It consists essentially of between end disks or cross braces a rotating shaft stretched axially parallel steel wires, where appropriate these steel wires have a circular cross-section and are made of stainless steel material are made.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt; und zwar zeigt Abb: i schematisch im Aufriß einen Bandtrockner mit Wendevorrichtung nach der Erfindung, Abb. 2 in Stirn- und Seitenansicht und im vergrößerten Maßstab die 'Wendevorrichtung -selbst: Gemäht Abb. i wird das endlose Förder-und Trocknungsband 3 über geeignet geformte Walzen 3', 3" horizontal geführt, und zwar innerhalb eines geschlossenen Kanals 8, der mit dem Guteinwurf i an einem Ende versehen ist. Eine Verteilerschnecke 2 dient zur gleichmäßigen Ausbreitung des Guts auf das Förderband.In the drawing, the subject matter of the invention is shown, for example; namely, Fig: i shows a schematic elevation of a belt dryer with a turning device according to the invention, Fig. 2 in front and side view and on an enlarged scale the 'turning device itself: mowed Fig. i the endless conveyor and drying belt 3 guided horizontally over suitably shaped rollers 3 ', 3 "within one closed channel 8, which is provided with the good slot i at one end. One Distribution screw 2 is used to spread the material evenly on the conveyor belt.
Das mit geringer Geschwindigkeit von dem Förderband durch den Trockenkanal geführte Gut (die Salzkristallschicht) wird nun durch oberhalb des Förderbandes 3 im Trocknungskanal ortsfest angeordnete besondere Wendevorrichtungen .4 aufgelockert bzw. gewendet. Diese Wendevorrichtungen (Abb. 2) bestehen je aus zwei auf einer Welle 1q: befestigten Stirnscheiben oder Armkreuzen 16; 16', zwischen denen dünne Stahldrähte 17 von kreisrundem Querschnitt achsparallel ausgespannt sind. Die Oberfläche dieser Stahldrähte ist sehr klein, so daß vermöge ihrer starken Krümmung und ihrer glatten Beschaffenheit keine Salzteilchen an ihr beim Durchgreifen der Salzschicht haften bleiben können, sondern auf das Trocknungsband zurückfallen.That at low speed from the conveyor belt through the drying tunnel Guided material (the salt crystal layer) is now through above the conveyor belt 3 special turning devices fixed in place in the drying tunnel .4 loosened up or turned. These turning devices (Fig. 2) each consist of two on one Shaft 1q: fixed end disks or cross braces 16; 16 ', between which thin Steel wires 17 of circular cross-section are stretched axially parallel. The surface this steel wire is very small, so that by virtue of its strong curvature and its smooth texture, no salt particles on it when reaching through the salt layer can stick, but fall back on the drying belt.
