Description

Die Erfindung betrifft eine Vorrichtung zur Heißluft-Trocknung entsprechend dem ersten Teil des Anspruches.The invention relates to a device for hot air drying according to the first part of the claim.

Bei einer bekannten Vorrichtung dieser Art (DE-A-2301 938) sind zwei Aufblastrocknungszonen und eine Durchsaugetrocknungszone in einer Ebene hintereinander angeordnet und jeweils mit einem gesonderten Ventilator versehen.In a known device of this type (DE-A-2301 938), two inflation drying zones and a suction drying zone are arranged one behind the other in a plane and are each provided with a separate fan.

Bekannt ist ferner eine Trocknungsvorrichtung (CH-A-408 845) bei der das Textilgut zunächst eine Gruppe von Heißluftdüsen passiert und dann über Siebtrommeln läuft. Dabei stehen die Düsen mit dem Gebläse einer Siebtrommel in Verbindung, so daß die aus den Trommeln gesaugte Luft vom Gebläse nochmals durch die Düsen dem Textilgut zugeführt wird.Also known is a drying device (CH-A-408 845) in which the textile material first passes through a group of hot air nozzles and then runs over sieve drums. The nozzles are connected to the blower of a sieve drum, so that the air sucked out of the drums is again fed into the textile material through the nozzles.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung entsprechend dem ersten Teil des Anspruches so auszubilden, daß die Heißluft-Trocknung mit einem besonders geringen anlagentechnischen und baulichen Aufwand erreicht wird und sich Trockner unterschiedlicher Größe und Leistung rationell fertigen lassen.The invention has for its object to design a device according to the first part of the claim so that the hot air drying is achieved with a particularly low system engineering and construction costs and dryers of different sizes and performance can be efficiently manufactured.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches gelöst.This object is achieved by the characterizing features of the claim.

Durch die Anordnung der beiden mit einem gemeinsamen Ventilator verbundenen, unterschiedlichen Trocknungszonen in zwei übereinanderliegenden Trocknungsetagen ergibt sich eine besonders kurze Gasführung und eine einfache, gedrängte Bauweise. Diese Etagen-Doppelfelder-Bauweise gestattet ferner eine sehr rationelle Fertigung von Trocknern unterschiedlicher Größe und Leistung, indem mehrere solche Doppelfelder unter Beibehaltung der genannten Luftführung aneinandergereiht werden.The arrangement of the two different drying zones connected to a common fan in two drying levels one above the other results in a particularly short gas flow and a simple, compact design. This double-field design also allows for a very efficient production of dryers of different sizes and performance, in that several such double fields are strung together while maintaining the air flow mentioned.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht. Es zeigen

  • Figur 1 einen Längsschnitt durch die erfindungsgemäße Vorrichtung,
  • Figuren 2 und 3 Schnitte längs der Linien 11-11 bzw. 111-111 der Fig. 1.
An embodiment of the invention is illustrated in the drawing. Show it
  • FIG. 1 shows a longitudinal section through the device according to the invention,
  • Figures 2 and 3 sections along lines 11-11 and 111-111 of Fig. 1st

Durch die Heißluft-Trocknungsvorrichtung 1 wird in Pfeilrichtung 2 das zu trocknende Textilgut 3 transportiert. Hierzu sind zwei mit Abstand übereinanderliegende Transportbänder 4 und 5 vorgesehen, auf deren oberes Trum 4a bzw. 5a das Textilgut 3 lose aufgelegt wird. Das obere und untere Transportband 4, 5 bilden dabei zwei übereinanderliegende Trocknungsetagen innerhalb des Gehäuses 6, so daß das Textilgut 3 zunächst auf dem Transportband 4 durch das Gehäuse 6 läuft, dann auf das untere Transportband 5 aufgelegt wird und zur Stirnseite 1a zurückläuft.The textile 3 to be dried is transported in the direction of arrow 2 by the hot air drying device 1. For this purpose, two conveyor belts 4 and 5 lying one above the other are provided, on the upper run 4a or 5a of which the textile material 3 is loosely placed. The upper and lower conveyor belt 4, 5 form two superimposed drying levels within the housing 6, so that the textile material 3 first runs on the conveyor belt 4 through the housing 6, then is placed on the lower conveyor belt 5 and runs back to the end face 1a.

Die Vorrichtung 1 ist in mehrere Trocknungszonen 7, 8, 9, 10 bzw. 11, 12, 13, 14 unterteilt, die in der genannten Reihenfolge vom Textilgut 3 nacheinander durchlaufen werden. Die Trocknungszonen 7, 9, 11 und 13 sind Aufblastrocknungszonen, in denen Heißluft in Form einer Konvektionsströmung mit der Ober- und Unterseite des Textilgutes in Berührung kommt. Die Trocknungszonen 8, 10, 12 und 14 sind Durchsaugetrocknungszonen, in denen das sich auf dem Transportband 4 bzw. 5 abstützende Textilgut von Heißluft durchströmt wird. Wie die Zeichung zeigt, folgen in Längsrichtung der Vorrichtung abwechselnd Aufblastrocknungszonen und Durchsaugetrocknungszonen aufeinander.The device 1 is divided into a plurality of drying zones 7, 8, 9, 10 and 11, 12, 13, 14, which are passed through in succession by the textile material 3. The drying zones 7, 9, 11 and 13 are inflation drying zones in which hot air in the form of a convection flow comes into contact with the top and bottom of the textile material. The drying zones 8, 10, 12 and 14 are suction drying zones in which the textile material supported on the conveyor belt 4 or 5 is flowed through by hot air. As the drawing shows, inflation drying zones and suction drying zones follow one another alternately in the longitudinal direction of the device.

Die Trocknungszonen 7 bis 10 der oberen Trocknungsetage liegen jeweils genau über den Trocknungszonen 11 bis 14 der unteren Trocknungsetage, wobei jeweils eine Aufblastrocknungszone und eine Durchsaugetrocknungszone einen Trocknungsabschnitt bilden und - wie anhand der Fig. 2 und 3 noch erläutert wird - einen gemeinsamen Ventilator aufweisen.The drying zones 7 to 10 of the upper drying level each lie exactly above the drying zones 11 to 14 of the lower drying level, an inflation drying zone and a suction drying zone forming a drying section and - as will be explained with reference to FIGS. 2 and 3 - have a common fan.

Die Aufblastrocknungszonen 7, 9, 11 und 13 sind gleichartig ausgebildet und besitzen oberhalb und unterhalb des das Textilgut 3 tragenden oberen Trums 4a, 5a des Transportbandes 4 bzw. 5 je eine Gruppe von mit Heißluft beaufschlagbaren, über die ganze Textilgutbreite reichenden Düsenkästen (obere Düsenkästen 15 und untere Düsenkästen 16). Diese Düsenkästen 15, 16 sind mit der Druckseite 17a eines den Heißluftstrom erzeugenden Ventilators 17 verbunden, wobei jedem Trocknungsabschnitt ein solcher Ventilator 17 zugeordnet ist. Vor der Ansaugseite 17b oder der Druckseite 17a des Ventilators ist außerdem noch ein geeigneter Wärmetauscher 18 bzw. 19 zur Aufheizung des Heißluftstromes angeordnet.The inflation drying zones 7, 9, 11 and 13 are of the same design and each have a group of nozzle boxes (upper nozzle boxes) which can be acted upon by hot air and extend over the entire width of the textile material, above and below the upper run 4a, 5a of the conveyor belt 4 or 5 15 and lower nozzle boxes 16). These nozzle boxes 15, 16 are connected to the pressure side 17a of a fan 17 which generates the hot air flow, such a fan 17 being associated with each drying section. A suitable heat exchanger 18 or 19 for heating the hot air flow is also arranged in front of the suction side 17b or the pressure side 17a of the fan.

Auch die Durchsaugetrocknungszonen 8, 10, 12, 14 sind gleichartig ausgeführt. In jeder Durchsaugetrocknungszone ist unter dem oberen Trum 4a bzw. 5a des Transportbandes 4 bzw. 5 ein über die ganze Textilgutbreite reichender Unterdruckkasten 20 angeordnet, der beispielsweise eine perforierte Oberseite 20a besitzt. In jedem Trocknungsabschnitt ist der Unterdruckkasten 20 an die Saugseite 17b des dort vorhandenen einzigen Ventilators 17 angeschlossen. Auf diese Weise ist in jedem Trocknungsabschnitt (z. B. in dem aus den Trocknungszonen 7 und 14 bestehenden Abschnitt) für die Aufblastrocknungszone und für die Durchsaugetrocknungszone nur ein einziger, gemeinsamer Umluftventilator erforderlich.The suction drying zones 8, 10, 12, 14 are also designed in the same way. In each suction drying zone, under the upper run 4a or 5a of the conveyor belt 4 or 5, there is a vacuum box 20 which extends over the entire width of the fabric and which, for example, has a perforated upper side 20a. In each drying section, the vacuum box 20 is connected to the suction side 17b of the single fan 17 present there. In this way, in each drying section (e.g. in the section consisting of drying zones 7 and 14) only a single, common air circulation fan is required for the inflation drying zone and for the suction drying zone.

Wie insbesondere Fig: 1 erkennen läßt, können beliebig viele Trocknungsabschnitte (enthaltend jeweils zwei übereinander angeordnete Trocknungszonen mit unterschiedlicher Luftführung) hintereinander angeordnet werden. Dies ermöglicht eine rationelle Fertigung von Trocknern unterschiedlicher Größe und Leistung.As can be seen in particular in FIG. 1, any number of drying sections (each containing two drying zones arranged one above the other with different air flow) can be arranged one behind the other. This enables rational production of dryers of different sizes and performance.

Die Luftführung dürfte nach den obigen Erläuterungen verständlich sein. Sie ist in den Fig. 2 und 3 zusätzlich durch die gestrichelten Pfeile 21 verdeutlicht.The air flow should be understandable according to the explanations above. It is additionally illustrated in FIGS. 2 and 3 by the dashed arrows 21.
