Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Trockenofendeckel des Trockenofens eine Absaugeinrichtung aufweist, mittels der feuchte Luft aus dem oberen Bereich des Trockenofens absaugbar ist. Hierdurch kann während des Entfeuchtungs- bzw. Trocknungsvorgangs Feuchtigkeit aus dem Innenraum des Trockenofens entfernt werden, so dass die Werkstücke besser als bei Trockenöfen gemäß dem Stand der Technik getrocknet werden können. Die Absaugung der feuchten Luft erfolgt im oberen Bereich des Trockenofens und damit mit einem hohen Wirkungsgrad, da sich dort die im Trockenofen befindliche feuchte Luft sammelt.These Task is inventively characterized solved, that the drying oven lid of the drying oven a suction device by means of the moist air from the upper portion of the drying oven is sucked. This can be during the Dehumidification or drying process Moisture from the interior of the drying oven, so that the workpieces are better as in drying ovens according to the state the technology can be dried. The extraction of moist air takes place in the upper part of the drying oven and thus with a high efficiency, since there in the drying oven collecting moist air.
In einer vorteilhaften Weiterbildung der Erfindung ist die Absaugeinrichtung in Form einer zum Innenraum des Trockenofens offenen deckelfesten Absaugrohrhaube ausgebildet. Eine derartige Absaugrohrhaube ist in einfacher Weise herstellbar, wobei darüber hinaus die Integration einer solchen Absaugrohrhaube in den Deckel ohne großen Aufwand bewerkstelligt werden kann.In An advantageous development of the invention is the suction device in the form of a lid open to the interior of the drying oven Extraction hood formed. Such a suction hood is can be produced in a simple manner, in addition to the integration Such a suction hood in the lid without much effort can be accomplished.
Wenn sich die Absaugrohrhaube etwa in Längsrichtung des Trockenofendeckels erstreckt, kann über die gesamte Längserstreckung des Trockenofens gleichmäßig die Feuchtigkeit aus dem oberen Bereich des Innenraums des Trockenofens abgesaugt werden. Hierbei sollte sich die Absaugrohrhaube etwa über die gesamte Längserstreckung des Trockenofendeckels bzw. des Trockenofens erstrecken.If the suction hood about in the longitudinal direction of the dry oven lid can extend over the entire longitudinal extent of the drying oven evenly Moisture is extracted from the upper area of the interior of the drying oven become. Here, the suction hood should be about the entire longitudinal extension of the Trockenofendeckels or the drying oven extend.
Für die gleichmäßige Absaugung der feuchten Luft aus dem oberen Bereich des Innenraums des Trockenofens ist es zweckmäßig, wenn die Absaugrohrhaube in Breitenrichtung des Trockenofendeckels bzw. des Trockenofens gesehen etwa mittig angeordnet ist.For uniform suction the moist air from the upper area of the interior of the drying oven it is useful if the suction hood in the width direction of the dry oven lid or of the drying oven is arranged approximately centrally.
Zweckmäßigerweise ist die Absaugrohrhaube an ein trockenofenfestes Anschlussrohr angeschlossen, durch das hindurch die feuchte Luft absaugbar ist. Gemäß einer weiteren vorteilhaften Ausführungsform des erfindungsgemäßen Trockenofendeckels ist bzw. sind zwischen der deckelfesten Absaugrohrhaube und dem trockenofenfesten Anschlussrohr zumindest ein, vorzugsweise mehrere Verbindungsrohre angeordnet, durch das bzw. die hindurch die feuchte Luft aus der Absaugrohrhaube zum Anschlussrohr führbar ist.Conveniently, If the extraction hood is connected to a dry kiln-proof connection pipe, through which the moist air is sucked. According to one further advantageous embodiment the dry oven lid according to the invention is or are between the cover-resistant suction hood and the Dry kiln fixed connection pipe at least one, preferably a plurality of connecting pipes arranged through which or through the humid air from the Extraction hood can be guided to the connection pipe.
Die Verbindungsrohre sind zweckmäßigerweise flexibel ausgestaltet, so dass ihre Abmessung in Breitenrichtung des Trockenofendeckels entsprechend dem Hub des Trockenofendeckels zwischen seiner Betriebs- und seiner Ruhestellung veränderbar ist.The Connecting pipes are expediently flexibly configured so that its dimension in the width direction dry oven lid according to the stroke of the dry oven lid changeable between his operating and his rest position is.
Wenn dem trockenofenfesten Anschlussrohr ein Trockner zugeordnet ist, der in Strömungsrichtung der feuchten Luft stromab der Öffnungsflächen der Verbindungsrohre zum Anschlussrohr angeordnet und mittels dem die feuchte Luft entfeuchtbar ist, kann die derart entfeuchtete Luft einem heißen Zufuhrtrockenluftstrom zum Trockenofen zugeführt werden, wodurch der Energieverbrauch für den Betrieb des Trockenofens erheblich reduziert werden kann.If the dry kiln fixed connection pipe is assigned a dryer, in the flow direction the moist air downstream of the opening surfaces of the Connecting pipes arranged to the connecting pipe and by means of the moist air is dehumidified, the dehumidified air can one hot Feed dry air flow to be fed to the drying oven, reducing energy consumption for the Operation of the drying oven can be significantly reduced.
Bei einem erfindungsgemäßen Verfahren zum Be- und Entlüften eines zwischen einem Flussmittelbad und einem Zinkbad einer Verzinkungsanlage angeordneten Trockenofens, dessen Innenraum mittels eines verstellbaren Trockenofendeckels abdeck- und freigebbar ist, wird feuchte Luft durch den den Trockenofen abdeckenden Trockenofendeckel hindurch aus dem oberen Bereich des Trockenofens abgesaugt. Während des Trocknungsvorgangs, d. h. im Betrieb des Trockenofens, wird hierdurch der Innenraum des Trockenofens entfeuchtet, mit der Folge, dass die im Trockenofen behandelten Werkstücke nach Beendigung der Entfeuchtung bzw. der Trocknung erheblich weniger mit Feuchtigkeit behaftet sind als bei aus dem Stand der Technik bekannten Verfahren.at a method according to the invention for Ventilation one between a flux bath and a zinc bath of a galvanizing plant arranged drying oven whose interior by means of an adjustable Trockenofendeckels is coverable and releasable, is humid air through the dry oven lid covering the drying oven aspirated from the top of the drying oven. During the Drying process, d. H. in the operation of the drying oven, thereby the interior of the drying oven dehumidifies, with the result that the workpieces treated in the drying oven after completion of the dehumidification or the drying are significantly less affected by moisture as in known from the prior art method.
Vorteilhaft wird hierbei die feuchte Luft durch eine deckelfeste Absaugrohrhaube und Verbindungsrohre hindurch in ein trockenofenfestes Anschlussrohr abgesaugt.Advantageous Here, the moist air through a cover-resistant suction hood and connecting pipes through into a dry oven fixed connection pipe aspirated.
Um den Trockenofendeckel mit einem geringen technischkonstruktiven Aufwand aus seiner Ruhe in seine Betriebsstellung und umgekehrt verfahren zu können, ist es zweckmäßig, wenn die Länge der Verbindungsrohre bei der Verstellung des Trockenofendeckels an die jeweilige Position des Trockenofendeckels und damit an den Abstand zwischen der deckelfesten Absaugrohrhaube einerseits und dem trockenofenfesten Anschlussrohr andererseits angepasst wird, was möglich ist, wenn die Verbindungsrohre in ausreichender Weise flexibel und in ihrer Längenabmessung veränderbar gestaltet sind.Around the dry oven lid with a low technical design Expense from his rest in his operating position and vice versa to be able to proceed it is useful if the length the connecting pipes during the adjustment of the drying oven lid to the respective position of the dry oven lid and thus to the Distance between the lid-resistant suction hood on the one hand and adapted to the dry kiln fixed connection pipe on the other hand, what possible is when the connecting pipes sufficiently flexible and in their length dimension variable are designed.
Um den Energieverbrauch bei der Trocknung zu reduzieren, wird vorgeschlagen, dass die aus dem oberen Bereich des Trockenofens abgesaugte feuchte Luft stromab der Verbindungsrohre entfeuchtet und nach ihrer Entfeuchtung einem Zufuhrtrockenluftstrom zum Trockenofen zugeführt wird.Around to reduce the energy consumption during drying, it is suggested that sucked from the upper area of the drying oven moist Air downstream of the connecting pipes dehumidified and after their dehumidification a feed dry air stream is supplied to the drying oven.
