Prallstrahltrockner für "bahnförmiges GutImpact jet dryer for "web-shaped goods
Die Erfindung "betrifft einen Prallstrahltrockner für bahnförmiges Gut, mit zwischen den senkrecht gegen die Gufbahn gerichteten schlitzförmigen Blasdüsen angeordneten Infrarotstrahlern.The invention "relates to an impingement dryer for web-shaped material, with between the vertical Slit-shaped blower nozzles arranged against the Gufbahn.
Durch die am 14.9.1950 ausgelegte deutsche Patentanmeldung ρ 19 999 D. Kl.8 Gr.1/05 ist ein kombinierter Prallstrahl-Strahlungstrockner mit von der zu beiden Seiten hin abfließenden Trocknungsluft überströmten stabförmigen Infrarotstrahler^bekannt geworden. Dem Vorteil der Aufheizung der umgewälzten Luft an den Strahlern steht der Nachteil der durch die Wärmeabgabe erheblich verminderten Strahlungsleistung gegenüber.Through the German patent application laid out on September 14, 1950 ρ 19 999 D. Kl.8 Gr.1 / 05 is a combined Impingement jet radiation dryer with drying air flowing off on both sides overflowing rod-shaped infrared emitters ^ become known. The advantage of heating the circulated Air at the radiators has the disadvantage that the radiant power is considerably reduced due to the heat dissipation opposite to.
Bei einem anderen bekannten Trockner mit Infrarot-Gas Strahlern wird die Gutbahn im Strahlungsbereich in der Bewegungsrichtung von Trocknungsluft überströmt. Auch hier wird den Strahlern infolge der Luftbewegung Wärme entzogen. Außerdem ist der Wirkungsgrad einer Überströmtrocknung erheblich schlechter als der einer Prallstrahltrocknung.In another known dryer with infrared gas emitters, the material web is in the radiation area overflows with drying air in the direction of movement. Here, too, the emitters as a result of the Air movement deprived of heat. In addition, the efficiency of an overflow drying is considerably worse than that of impingement drying.
Der Erfindung liegt die Aufgabe zu Grunde, sowohl die Strahlungswärme als auch die Umluftwärme maximal auszunutzen und außerdem eine berührungsfreie Führung der Gutbahn zu erzielen, d.h. den Trockner als Sehwebebahntrockner auszubilden.The invention is based on the object both to use the radiant heat as well as the circulating air heat to the maximum and also a non-contact To achieve guidance of the material web, i.e. to train the dryer as a visual web dryer.

Diese Aufgabe wird bei einem Trockner nach dem Gattungsbegriff des Patentanspruchs erfindungsgemäß dadurch gelöst, daß ^jeweils zwei Blasdüsen einen gemeinsamen Düsenkasten "besitzen, dessen vordere und hintere Wand sich jede in eine Düsenwand fortsetzen, und daß in dem ein Vielfaches der Düsenschlitzbreite betragenden Zwischenraum zwischen den beiden Düsen ein oder, in einer Reihe, mehr als ein Infrarot-Gasstrahler angeordnet ist.This object is achieved according to the invention in a dryer according to the preamble of the patent claim solved in that ^ each two blowing nozzles have a common nozzle box "whose the front and rear walls each continue into a nozzle wall, and that in which a multiple the gap between the two nozzles corresponding to the width of the nozzle slot or, in a row, more than one infrared gas heater is arranged.
In dem Zwischenraum zwischen den aus den "beiden Düsen austretenden Trocknungsluftstrahlen bildet sich bekanntlich ein statisches Druckkissen aus ( DT OS 1 904 101, S. 19, Abs.2 >, sodaß die Gasstrahler nicht mit strömender Luft in Berührung kommen und ihre Strahlung sowie ihre heißen Abgase unvermindert an die Gutbahn gelangen. Letzteres wird noch durch den Sog, den die aus den Düsen austretenden Trocknungsluftstrahlen ausüben, unterstützt. Erst wenn die Strahlungswärme, die Gaswärme und die Umluftwärme an die Gutbahn abgegeben sind, wird die Trocknungsluft jeweils zwischen den Düsenkästen senkrecht von der Gutbahn abgeführt.Forms in the space between the jets of drying air emerging from the "two nozzles As is known, a static pressure pad is made from (DT OS 1 904 101, p. 19, paragraph 2 > so that the gas ejectors do not come into contact with flowing air come and their radiation as well as their hot exhaust gases reach the Gutbahn undiminished. The latter is made possible by the suction of the drying air jets emerging from the nozzles exercise, supports. Only when the radiant heat, the gas heat and the circulating air heat to the Good web are released, the drying air is vertically from between the nozzle boxes removed from the Gutbahn.
Es ergibt sich demnach eine hohe Ausnutzung der Wärme, wie sie bislang bei solchen kombinierten Trocknern nicht erreicht wurde.This results in a high utilization of the heat, as it has been combined with such up to now Dryer was not reached.

Anhand der Zeichnung, die sich auf die Darstellung des Prinzips beschränkt, wird die Erfindung im folgenden näher erläutert.Based on the drawing, which is limited to the representation of the principle, the invention is described below explained in more detail.
Unterhalb der Gutbahn 6 sind, sich senkrecht zur Zeichenebene über die Gutbahnbreite erstreckend, Düsenkasten 2 angeordnet, deren Abstände voneinander auch durch die Eigenschaften der Gutbahn und die auf sie wirkenden Zugkräfte bestimmt sind. Jeder Düsenkasten 2 weist zwei senkrecht gegen die Gutbahn 6 gerichtete Schlitzdüsen auf,.die stellvertretend durch die aus ihnen austretenden Trocknungsluft strahl en mit 1 bezeichnet sind.Below the material path 6, extending perpendicular to the plane of the drawing over the material path width, Arranged nozzle box 2, the distances from each other also by the properties of the material web and the tensile forces acting on them are determined. Each nozzle box 2 has two perpendicular to the Good web 6 directed slot nozzles, .the representative by the drying air emerging from them rays are denoted by 1.
Zwischen den beiden Düsen 1 jedes Düsenkastens 2 ist, den Zwischenraum 5 möglichst ausfüllend, ein bekannter Infrarot-Gasstrahler 4- bzw." eine sich über die Gutbahnbreite erstreckende Reihe aus solchen Strahlern angeordnet. In dem einerseits durch die beiden Trocknungsluftstrahlen 1, andererseits durch die Gutbahn 6 und den oder die Strahler 4- umschlossenen Raum 3 bildet sich ein statisches, die Gutbahn 6 stützendes Luftkissen aus, sodaß in diesem Raum 3;3praktisch keine Luftbewegung stattfindet. Die Trocknungsluft wird, nachdem sie die Gutbahn 6 beaufschlagt hat, in Richtung der Pfeile 7 zwischen den Düsenkästen 2 senkrecht von der Gutbahn weggeführt. Wie üblich, wird auch · im vorliegendem Fall mit Luftumwälzung gearbeitet.Between the two nozzles 1 of each nozzle box 2, the space 5 is filled as much as possible known infrared gas emitter 4 or "a row extending over the width of the material web arranged such radiators. In the one hand by the two drying air jets 1, on the other hand a static, the material web 6 supporting air cushion, so that in this space 3; 3 practically no air movement takes place. The drying air is, after it has acted on the web 6, in the direction the arrows 7 between the nozzle boxes 2 perpendicularly away from the material path. As usual, also in the present case worked with air circulation.
509820/0424509820/0424
Es versteht sich, daß auch Infrarotstrahler
anderer Art verwendet werden können, jedoch ist der Gesamtwirkungsgrad aus den ol>en genannten
Gründen am höchsten "bei Verwendung
von Gasstrahlern.It goes without saying that infrared emitters of other types can also be used, but the overall efficiency is highest when used for the reasons mentioned above
of gas emitters.
