Description
Verfahren zum Schnelltrocknen von Naßgut Für alle Feuergas- oder Heißlufttrockner ist zutreffend, daß die Wärme abgebenden Heizgase sich fortbewegen, "weil sie einmal dis Brüder abführen, andererseits für neue Heizgase Raum freigeben müssen. Das Trokkengut kann jedoch je nach Art des Trockners stillregen, umgewendet oder auch fortbewegt werden. Das Trocknen im ersteren erfordert die längste, im letzteren die kürzeste Trockenzeit. Bei Schnelltrocknern, die nach dem Gleichstromprinzip .arbeiten, haben Heizgase und Trockengut gleiche Bewegungsrichtung. Die Anfangstemperatur kann daher je nach der Anfangsfeuchtigkeit bis zu 8oo° C gewählt werden, während bei den üblichen Lufttrocknern die Grenze der Erhitzung der Luft meist bei etwa 7o bis 8o°, in Ausnahmefällen auch bei i oo° C, liegt, so daß die Trockenzeit auf Sekunden Moder Bruchteile einer Sekunde verkürzt wird.Process for the rapid drying of wet goods For all fire gas or hot air dryers it is true that the heat-emitting heating gases move, "because they once Discharge the brothers, on the other hand have to free up space for new heating gases. The dry goods however, depending on the type of dryer, it can still rain, turn around or move around will. Drying in the former requires the longest, in the latter the shortest Dry season. In the case of high-speed dryers that work according to the direct current principle, have Heating gases and dry goods in the same direction of movement. The initial temperature can therefore depending on the initial humidity up to 8oo ° C can be selected, while with the usual Air dryers usually set the limit for heating the air at around 7o to 8o °, in exceptional cases also at 100 ° C, so that the drying time to a few seconds moderately fractions of a Second is shortened.
Bei den üblichen Schnelltrocknern fördern die Heizgase selbst das Trockengut über eine senkrecht verlaufende Trockenstrecke im Schwebezustand. Das Gut verläßt den Heizgasstrom, bevor die Feuchtigkeit des Trockengutes unter ein bestimmtes Maß sinkt, um Verbrennungen zu verhüten.With the usual rapid dryers, the heating gases themselves promote this Material to be dried over a vertical drying section in a suspended state. That Well leaves the flow of heating gas before the moisture of the dry material enters decreases to a certain extent to prevent burns.
Das ineue Verfahren erzielt dasselbe Ergebnis in Anlehnung an die Schwebetrocknung dadurch, daß das Trockengut mit großer Geschwindigkeit unter Benutzung mechanischer Fortbewegungsmittel bei Temperatunen bis zu 8oo° waagerecht weitergetragen wird. Main benötigt alsdann keinen mit hohem Unterdruck ,arbeitenden Exhaustor, da der Schornsteinzug genügt, um die Heizgase fortzubewegen und die Brüder abzuführen. Es kann hierbei die Geschwindigkeit des Trockengutes sogar größer sein als die der sehr heißem Feuergase, was von Vorteil ist. Weiterhin ergibt sich bei dem neuen Verfahren eine geringere Länge des Trockenweges, da die Geschwindigkeit des heißen Feuergasstromes geringer ist, was unbedenklich gemacht werden kann, wenn das Trockengut nur am Ende des Trockenweges so viel Endfeuchte besitzt, daß eine Verbrennung nicht eintritt.The inew process achieves the same result based on the Floating drying in that the material to be dried is using at high speed mechanical means of locomotion at temperatures of up to 8oo ° horizontally will. Main then does not need an exhaustor working with high negative pressure, because the chimney draft is enough to move the heating gases away and to lead the brothers away. The speed of the dry goods can even be greater than that of the very hot fire gases, which is an advantage. Furthermore, with the new Process a shorter length of the drying path because the speed of the hot Fire gas flow is lower, which can be made harmless if the dry material only has so much final moisture at the end of the drying path that combustion does not occur entry.
Auch kann. anschließend an den Trockenweg mit Hilfe einer Trennvorrichtung das gröbere und noch feuchte Trockengut ausgeschieden und in bekannter Weise nach nochmaliger Vermahlung wieder in den Trokkenweg aufgegeben werden.Also can. then on the dry path with the help of a separator the coarser and still moist dry material excreted and afterwards in a known manner regrind to be abandoned in the Trokkenweg.
Zweckmäßig werden als Förderer für das Trockengut Metallbänder benutzt. Besitzt das Trockengut aber Band- oder Fadenform, so kann dieses selbst zur Förderung dienen.Metal belts are expediently used as conveyors for the dry material. However, if the dry material is in the form of a band or thread, it can be used for conveying purposes itself to serve.
Der Trockner eignet sich für jedes Naßgut anorganischen oder pflanzlichen Ursprungs, ebenso für Textilwaren jeder Art und zum Trocknen von Wäsche. Auch läßt sich derselbe fahrbar ausführen und auf Schiffen zum Trocknen von Fischen einbauen. rend die gröberen überschläge vom Sieb lt m eine Mahlvorrichtung h geleitet werden. Das in der Mühle h zerkleinerte Gut wird auf beliebige Weise zur Aufgabestellle des Trock-.ners zurückgeführt und nochmals getrocknet.The dryer is suitable for any inorganic or vegetable wet material Origin, also for textile goods of all kinds and for drying laundry. Also lets run the same mobile and install it on ships for drying fish. rend the coarser flashovers are passed from the sieve to a grinding device. That The material comminuted in the mill h can be used in any way for the task of the Dryers returned and dried again.
Abb. IV ist eine fahrbare Trockenanlage 'mit den gleichen Teilen gemäß Buchstaben a bis h der Abb.III. L ist das Wagengestell und m und ja die Räder des Wagens. In der Zeichnung sind vier Ausführungsmöglichkeiten seines Schnelltrockners mit laufendem Band wiedergegeben.Fig. IV is a mobile drying system 'with the same parts according to letters a to h of Fig. III. L is the carriage frame and m and yes the wheels of the carriage. The drawing shows four possible designs of his rapid dryer with a moving belt.
