Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Schon in dem Buch

Figure imgb0001
Trockner und Trocknungsverfahren" von K. Kröll, Springer-Verlag 1959, Seite 37, wird hervorgehoben, daß das Trocknen in reinem Heißdampf besonders wirtschaftlich ist, weil dabei keine von außen kommende Luft angewärmt zu werden braucht. Zur Wirtschaftlichkeit tragen noch weitere Faktoren bei: die Abluftreinigung entfällt, weil keine Abluft vorhanden ist. Die im Abdampf enthaltene latente Wärme kann relativ einfach durch Kondensation zurückgewonnen werden. Wegen der geringen Dichte des Dampfes ist der Bedarf an elektrischer Energie für die Umwälzung des Trocknungsmediums etwa 1/3 niedriger als bei einem mit Heißluft betriebenen Trockner.Already in the book
Figure imgb0001
Dryer and drying process "by K. Kröll, Springer-Verlag 1959, page 37, emphasizes that drying in pure superheated steam is particularly economical because no air coming from outside needs to be warmed up. Other factors also contribute to economy: Exhaust air purification is eliminated because there is no exhaust air. The latent heat contained in the exhaust steam can be recovered relatively easily by condensation. Because of the low density of the steam, the electrical energy required to circulate the drying medium is about 1/3 lower than with one Hot air operated dryer.

Ein weiterer Vorteil, der sich speziell auf die Trocknung von Textilien bezieht, ist ebenfalls aus dem angegebenen Buch bekannt (Seite 177): man sagt der Heißdampftrocknung nach, sie schone die Ware, verleihe ihr einen guten Griff und lasse die Farben frisch und klar hervortreten.Another advantage that relates specifically to the drying of textiles is also known from the specified book (page 177): hot steam drying is said to protect the goods, give them a good grip and let the colors appear fresh and clear .

Die Heißdampftrocknung bietet sich nicht nur für Waren aus nativen Fasern an, sondern auch für solche, die aus synthetischen Fasern hergestellt sind. Hier kann mit Temperturen von 150 bis 300°C gearbeitet werden.Hot steam drying is not only suitable for goods made from native fibers, but also for those made from synthetic fibers. Temperatures from 150 to 300 ° C can be used here.

In der DE 35 11 950 A1, von der die Erfindung ausgeht, wird ein Heißdampftrockner beschrieben, dessen Gehäuse als gas- und dampfdichte Glocke ausgebildet ist. Die Warenbahn wird, z. B. mit Spannketten, durch Schlitze, die im Boden des Gehäuses angebracht sind, in dieses hinein- und wieder herausgeführt. Die Schlitze sind mit besonderen Abdichtungen versehen.DE 35 11 950 A1, from which the invention is based, describes a superheated steam dryer whose housing is designed as a gas- and vapor-tight bell. The web is z. B. with tension chains, through slots that are made in the bottom of the housing into and out of this. The slots are provided with special seals.

Es ist aber - wie schon in dem erwähnten Buch (Seite 103) genannt - in der Praxis nicht ganz einfach, Heißdampftrockner für durchlaufenden Betrieb, z. B. für Gewebebahnen, so dicht zu bauen, daß nirgends Luft eindringt. Probleme bereiten nicht nur die Schlitze für die warenführenden Spannketten, sondern z. B. auch Leitungen, die die Gehäusewand durchdringen, Türen oder Durchbrüche für Siebe.However, as already mentioned in the book mentioned (page 103), it is not very easy in practice to use superheated steam dryers for continuous operation, e.g. B. for fabric webs to build so tight that no air penetrates anywhere. Cause problems not only the slots for the tension chains, but e.g. B. also lines that penetrate the housing wall, doors or openings for screens.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 mit einfachen Mitteln so auszubilden, daß das Eindringen von Luft weitgehend unterdrückt wird.The invention has for its object to design a device according to the preamble of claim 1 with simple means so that the penetration of air is largely suppressed.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Auf diese Weise werden die kritischen Stellen, an denen Leckströme erfahrungsgemäß meistens auftreten, in den Boden des Gehäuses verlegt. Die übrigen Wandungen sind von Durchbrüchen völlig frei.This object is achieved according to the invention by the characterizing features of claim 1. In this way, the critical points, where experience has shown that leakage currents usually occur, are laid in the bottom of the housing. The other walls are completely free of breakthroughs.

Weitere vorteilhafte Merkmale der Erfindung sind Gegenstand der Ansprüche 2 bis 7.Further advantageous features of the invention are the subject of claims 2 to 7.

Die Zeichnung dient zur Erläuterung der Erfindung anhand eines vereinfacht dargestellten Ausführungsbeispiels.

  • Figur 1 zeigt eine Seitenansicht einer Vorrichtung gem. der Erfindung.
  • Figur 2 zeigt einen Querschnitt der Vorrichtung gem. Figur 1.

  • Figure 2 shows a cross section of the device according to. Figure 1

Ein Gehäuse 1 hat Stirnwände 2, 3, Seitenwände 4, 5, eine Decke 6 und einen Boden 7. Mit Ausnahme des Bodens 7 sind alle Wandungen 2 bis 6 von Öffnungen, Leitungsdurchführungen und dergleichen Durchbrechungen völlig frei. Die Decke 6 ist vorzugsweise beheizt, um Kondensation insbesondere im Aufheizstadium zu vermeiden. Das Gehäuse 1 ist hochgestellt, so daß zwischen dem Boden 7 und dem Hallenflur 8 ein Abstand besteht.A housing 1 has end walls 2, 3, side walls 4, 5, a ceiling 6 and a floor 7. With the exception of the floor 7, all the walls 2 to 6 are completely free of openings, cable bushings and similar openings. The ceiling 6 is preferably heated in order to avoid condensation, particularly in the heating stage. The housing 1 is raised so that there is a distance between the floor 7 and the hallway 8.

Das Gehäuse 1 umfaßt mehrere baukastenartig aneinandergereihte Kammern 9 bis 14. Die Stoßstellen der Wandungen benachbarter Kammern sind abgedichtet. Alle Wandungen sind mit einer Wärmedämmung versehen.The housing 1 comprises a plurality of chambers 9 to 14 lined up in a modular manner. The joints of the walls of adjacent chambers are sealed. All walls are provided with thermal insulation.

Zwei endlose, mit Kluppen und/oder Nadelleisten bestückte Spannketten 15, vorzugsweise in schmierungsfreier Ausführung, sind in vertikalen Ebenen über Umlenkrollen 16 geführt. Von einem Einlaufpult 17, bei dem eine Warenbahn 18 den Spannketten 15 zugeführt wird, laufen die warenführenden Kettentrume senkrecht nach oben durch einen im Boden 7 angebrachten Einlaufschlitz 19 in die Kammer 9 ein. Die Spannketten 15 durchlaufen an Kettenbahnen 20, die zwecks Anpassung an die Breite der Warenbahn 18 in Querrichtung verschieblich sind, das Gehäuse 1 in Längsrichtung und werden aus der Endkammer 14 senkrecht nach unten durch einen Auslaufschlitz 21 des Bodens 7 wieder herausgeführt. Nach Ablösung der behandelten , insbesondere getrockneten Warenbahn 18, die über eine Rolle 22 abgezogen wird, laufen die leeren Kettentrume von einem Auslaufständer 23 unter dem Boden 7 des Gehäuses 1 zum Einlaufpult 17 zurück.Two endless tension chains 15 equipped with clips and / or needle bars, preferably in a lubrication-free design, are guided in vertical planes over deflection rollers 16. From an inlet desk 17, in which a web 18 is fed to the tensioning chains 15, the chain strands leading the goods run vertically upwards through an inlet slot 19 in the bottom 7 into the chamber 9. The tension chains 15 pass through chain housing 20 in the longitudinal direction on chain tracks 20, which are displaceable in the transverse direction for the purpose of adaptation to the width of the material web 18, and are led out of the end chamber 14 vertically downwards through an outlet slot 21 of the bottom 7. After detachment of the treated, in particular dried, web of material 18, which is drawn off via a roller 22, the empty chain runs run back from an outlet stand 23 under the floor 7 of the housing 1 to the inlet desk 17.

Zwischen den einzelnen Kammer 9 bis 14 sind Trennwände angeordnet. Jede Trennwand ist mit einer Durchlaßöffnung für die Warenbahn 18, die Spannketten 15 und die Kettenbahnen 20 versehen.Partitions are arranged between the individual chambers 9 to 14. Each partition is provided with a passage opening for the web 18, the tension chains 15 and the chain tracks 20.

Über und unter der Warenbahn 18 sind in den Kammern 9 bis 14 Düsenkästen 24, 25 angeordnet, die in Figur 1 der Übersichtlichkeit halber nur in der Kammer 12 angedeutet sind. Sie sind auf der Seite, die der Warenbahn 18 zugekehrt ist, mit durch Pfeile 26 angedeuteten Düsenöffnungen zum Aufblasen von Dampf auf die Warenbahn 18 versehen. Jeder Düsenkasten 24, 25 ist von mehreren Rückströmkanälen 27 durchsetzt, die - verglichen mit den Düsenöffnungen 26 - einen großen Querschnitt haben und sich von der Unterseite zur Oberseite des Düsenkastens 24, 25 erstrecken.Above and below the web 18, nozzle boxes 24, 25 are arranged in the chambers 9 to 14, which are only indicated in the chamber 12 in FIG. 1 for the sake of clarity. They are provided on the side facing the web 18 with nozzle openings indicated by arrows 26 for inflating steam onto the web 18. Each nozzle box 24, 25 is penetrated by a plurality of backflow channels 27 which - compared to the nozzle openings 26 - have a large cross section and extend from the underside to the top of the nozzle box 24, 25.

Einströmseitig steht jeder Düsenkasten 24, 25 in offener Verbindung mit einem senkrechten Schacht 28, der nach außen von der Seitenwand 4 begrenzt ist. Die Düsenkästen 24, 25 sind von einem Sammelraum 29 umgeben, der durch eine waagerechte Zwischendecke 30 von einem dem Boden 7 benachbarten, in den Schacht 28 einmündenden Strömungskanal 31 getrennt ist.On the inflow side, each nozzle box 24, 25 is in open connection with a vertical shaft 28 which is delimited from the outside by the side wall 4. The nozzle boxes 24, 25 are surrounded by a collecting space 29, which is separated by a horizontal false ceiling 30 from a flow channel 31 adjacent to the floor 7 and opening into the shaft 28.

In der Nähe der dem Schacht 28 gegenübertiegenden Seitenwand 5 ist ein Radialgebläse 32 angeordnet, welches über eine den Boden 7 durchdringende Welle 33 mit einem unter dem Boden 7 angeordneten Antriebsmotor 34 gekoppelt ist. Das Gebläse 32 steht saugseitig über einen Ansaugtrichter 35, der am Rand einer Öffnung des Zwischenbodens 30 befestigt ist, mit dem Sammelraum 29 in Verbindung. Nach dem Radialgebläse 32 ist in dem Strömungskanal 31 ein Sieb 37 angeordnet, welches durch einen Schlitz des Bodens 7 herausnehmbar ist, z. B. zum Zweck der Reinigung.In the vicinity of the side wall 5 opposite the shaft 28, a radial fan 32 is arranged, which is driven by a shaft 33 penetrating the bottom 7 is coupled to a drive motor 34 arranged under the floor 7. The blower 32 is connected to the collecting space 29 on the suction side via an intake funnel 35 which is attached to the edge of an opening of the intermediate floor 30. After the radial fan 32, a sieve 37 is arranged in the flow channel 31, which can be removed through a slot in the bottom 7, for. B. for the purpose of cleaning.

In dem Strömungskanal 31 ist ein Heizregister 38 angeordnet, das an Leitungen 39 zum Zuführen und Abführen eines Heizmediums angeschlossen ist. Die Leitungen 39 sind durch den Boden 7 hindurchgeführt.A heating register 38 is arranged in the flow channel 31 and is connected to lines 39 for supplying and discharging a heating medium. The lines 39 are passed through the bottom 7.

In die Einlaufkammer 9 mündet eine den Boden 7 durchdringende Leitung 40 zum Einblasen von Dampf, z. B. bei reiner Thermobehandlung trocknener Warenbahnen oder beim Anfahren eines Trockners. Beiderseits des Einlaufschlitzes 19 und des Auslaufschlitzes 21 sind Saugkästen 41 angeordnet, deren der Warenbahn 18 zugekehrte Wand mit nicht gezeichneten Saugöffnungen versehen ist. Die Saugkästen 41 sind durch nicht dargestellte Rohrleitungen mit einer Einrichtung zur Wärmerückgewinnung verbunden, z. B. mit einer Kondensationseinrichtung.In the inlet chamber 9 opens a line 40 penetrating the bottom 7 for blowing steam, z. B. with pure thermal treatment of dry webs or when starting a dryer. Suction boxes 41 are arranged on both sides of the inlet slot 19 and the outlet slot 21, the wall of which facing the web 18 is provided with suction openings (not shown). The suction boxes 41 are connected by pipes, not shown, to a device for heat recovery, for. B. with a condensation device.

Im Boden 7 sind auch Einstiegluken 42 angebracht, ggbf. auch Durchführungen für in der Zeichnung nicht dargestellte Meßgeräte, wie Pyrometer oder Feuchtemeßgeräte.In the floor 7 there are also access hatches 42, if necessary. also bushings for measuring devices not shown in the drawing, such as pyrometers or moisture measuring devices.

Bei einer anderen, in der Zeichnung nicht dargestellten Ausführung der Erfindung ist statt des Heizregisters 38 ein Gasbrenner als Erhitzer vorgesehen. In diesem Falle sind die Leitungen für Gas und Verbrennungsluft in entsprechender Weise durch den Boden 7 hindurchgeführt.In another embodiment of the invention, not shown in the drawing, a gas burner is provided as the heater instead of the heating register 38. In this case, the lines for gas and combustion air are passed through the floor 7 in a corresponding manner.

Im Trocknungsbetrieb wird der Vorrichtung lediglich in der Anfahrphase über die Leitung 40 Heißdampf zugeführt, um die vorhandene Luft zu verdrängen. Durch die Trocknung der Warenbahn 18 wird fortwährend neuer Dampf erzeugt. In jeder einzelnen Kammer 9 bis 14 wird der Dampf durch ein Gebläse 32 umgewälzt und durch ein Heizregister 38 auf der vorgeschriebenen Temperatur gehalten. Der Dampf wird durch die Düsen 26 auf die Warenbahn 18 aufgeblasen und gelangt durch die Rückströmkanäle 27 oder die zwischen benachbarten Düsenkästen 24, 25 bestehenden Zwischenräume in den Sammelraum 29. Der Dampf erzeugt in dem gesamten Innenraum des Gehäuses 1 einen Überdruck. In dem Schacht 28 und dem Strömungskanal 31, d. h. insbesondere in der Nähe des Bodens 7, in dem die Durchführungen der Wellen 33, der Leitungen 39, 40, das Sieb 37, die Einstiegluke 42 und ggbf. weitere Durchführungen angebracht sind, ist der Überdruck relativ hoch. Aber auch in den Bereichen, die saugseitig mit den Gebläsen 32 in Verbindung stehen, stellt sich relativ zur Atmosphäre ein geringer Überdruck ein. Überschußdampf entweicht durch den Einlaufschlitz 19 und den Auslaufschlitz 21, wird durch die Saugkästen 41 abgezogen und z. B. einer Kondensationseinrichtung zwecks Wärmerückgewinnung zugeführt. Die abgezogene Dampfmenge entspricht im stationären Betrieb genau der Dampfmenge, die beim Trocknen aus der Warenbahn 18 ausgetrieben wird.In the drying mode, the device is supplied with superheated steam via line 40 only in the start-up phase in order to displace the existing air. The drying of the web 18 continuously generates new steam. In each individual chamber 9 to 14, the steam is circulated by a fan 32 and kept at the prescribed temperature by a heating register 38. Of the Steam is blown onto the material web 18 through the nozzles 26 and reaches the collecting space 29 through the return flow channels 27 or through the gaps existing between adjacent nozzle boxes 24, 25. The steam generates an overpressure in the entire interior of the housing 1. In the shaft 28 and the flow channel 31, ie in particular in the vicinity of the bottom 7, in which the passages of the shafts 33, the lines 39, 40, the sieve 37, the entry hatch 42 and possibly. more bushings are installed, the pressure is relatively high. But even in the areas that are connected to the blowers 32 on the suction side, a slight excess pressure is established relative to the atmosphere. Excess steam escapes through the inlet slot 19 and the outlet slot 21, is drawn off through the suction boxes 41 and z. B. a condensation device for heat recovery. The amount of steam withdrawn in stationary operation corresponds exactly to the amount of steam that is expelled from the web 18 during drying.

Ein zusätzlicher Vorteil der Erfindung besteht darin, daß die glatten, von Durchbrüchen freien Wandungen sehr einfach herzustellen und daher besonders kostengünstig sind.An additional advantage of the invention is that the smooth, breakthrough-free walls are very easy to manufacture and are therefore particularly inexpensive.
