Abstract
Description
Die Erfindung bezieht sich auf eine Durchlauftrocknungsanlage, insbesondere zur thermischen Aushärtung von Lacken oder Klebstoffen an Kraftfahrzeugkarosserieteilen, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a continuous drying plant, in particular for the thermal curing of paints or adhesives on motor vehicle body parts, according to the preamble of patent claim 1.

Aufgabe der Erfindung ist es, eine Durchlauftrocknungsanlage der eingangs genannten Art zu schaffen, die eine deutlich erhöhte Energieeffizienz unter Vermeidung unzulässiger Wärmespannungen an den die Anlage durchlaufenden Bauteilen, also insbesondere den lackierten oder klebstoffbeschichteten Kraftfahrzeugkarosserieteilen, aufweist.The object of the invention is to provide a continuous drying plant of the type mentioned, which has a significantly increased energy efficiency while avoiding inadmissible thermal stresses on the system passing through the components, ie in particular the painted or adhesive-coated motor vehicle body parts.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 gekennzeichnete Durchlauftrocknungsanlage gelöst.This object is achieved by the characterized in claim 1 continuous drying plant.
Erfindungsgemäß wird durch die stufenweise Erwärmung und Abkühlung längs separater Aufwärm- und Abkühlzonen in Verbindung mit einer zwangsluftgesteuerten Wärmeübertragung von den einzelnen Kühlzonen jeweils gezielt zu den temperaturmäßig entsprechenden Heizzonen eine hocheffiziente Energienutzung des in den Bauteilen, also insbesondere den Kraftfahrzeugkarosserieteilen auslassseitig der Trocknungskammer enthaltenen Wärmepotenzials zum sukzessiven Aufheizen der Bauteile auf Trocknungstemperatur erreicht, mit dem Ergebnis, dass die erfindungsgemäße Trocknungsanlage unter Einhaltung eines zur Vermeidung unzulässiger Thermospannungen erforderlichen Temperaturprofils mit einem deutlich reduzierten Wärmebedarf arbeitet.According to the invention, by the stepwise heating and cooling along separate heating and cooling zones in connection with a forced air-controlled heat transfer from the individual cooling zones specifically targeted to the corresponding heating zones a highly efficient energy use of the heat potential contained in the components, ie in particular the motor vehicle body parts outlet side of the drying chamber for successive Heating of the components reached to drying temperature, with the result that the drying plant according to the invention works in compliance with a required to avoid impermissible thermal stresses temperature profile with a significantly reduced heat demand.
In besonders bevorzugter Ausgestaltung der Erfindung erfolgt die Wärmeübertragung von den einzelnen Kühl- an die entsprechenden Heizzonen unter Zwischenschaltung eines Wärmetauschers, wodurch zwar ein geringfügig verlustbehafteter Wärmetransport in Kauf genommen, aber wirksam verhindert wird, dass die in der Heizzonenluft enthaltenen Lösungsmittel- oder sonstige Stoffe in die Kühlstrecke gelangen und eine dort vorhandene Reinluftatmosphäre verunreinigen.In a particularly preferred embodiment of the invention, the heat transfer from the individual cooling takes place to the corresponding heating zones with the interposition of a heat exchanger, which admittedly a slightly lossy heat transport accepted, but effectively prevents the contained in the Heizzonenluft solvent or other substances in enter the cooling section and contaminate an existing clean air atmosphere.
Die den Heizzonen durch die Zwangsluftströmung zugeführte Wärmemenge ist, wie bevorzugt, auf einfache Weise durch eine entsprechende Regelung des für die Zwangslufterzeugung ohnehin benötigten Gebläses regulierbar, und ferner ist zum Ausgleich des auch bei der erfindungsgemäßen Trocknungsanlage noch verbleibenden Wärmebedarfs vorzugsweise zumindest ein Zusatzbrenner im Zuge der Zwangsluftzufuhr zu den Heizzonen angeordnet.The amount of heat supplied to the heating zones by the forced air flow is, as preferred, easily regulated by a corresponding control of the blower required anyway for the forced air generation, and further is at least one auxiliary burner in the course of the still remaining heat demand also in the drying system according to the invention Forced air supply to the heating zones arranged.
Die Erfindung wird nunmehr an Hand eines Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert. Diese zeigt in ihrer einzigen Figur eine einfindungsgemäß ausgebildete Durchlauflufttrocknungsanlage für lackierte Kraftfahrzeugkarosserien in stark schematisierter Darstellung.The invention will now be described with reference to an embodiment in conjunction with the drawings. This shows in its single figure a Einfindungsgemäß trained continuous air drying system for painted motor vehicle bodies in a highly schematic representation.
