Die Erfindung bezieht sich gattungsgemäß auf eine Vorrichtung für die Reparatur und für das Endlosmachen von Förderbändern aus Gummi oder Kunststoff mit Pressenplatten, die Heizkanäle und Kühlkanäle aufweisen, wobei in den Heizkanälen elektrische Heizeinrichtungen angeordnet sind und in die Kühlkanäle ein Kühlmedium einleitbar ist. The invention relates generically to a device for the repair and the endless making of conveyor belts made of rubber or plastic with press plates that have heating channels and cooling channels, with the heating channels electrical heating devices are arranged and a cooling medium in the cooling channels can be initiated. Bei den (aus der Praxis) bekannten Vorrichtungen der beschriebenen Gattung und Zweckbestimmung ist das Kühlmedium Wasser. Es strömt durch die Kühlkanäle und nimmt die abzuführende Wärme im flüssigen Zustand als fühlbare Wärme auf. Um eine kurzzeitige Kühlung zu erreichen, wie es insbesondere bei Förderbändern aus Kunststoff angestrebt wird, ist eine große Kühlwassermenge erforderlich. Das gesamte angeschlossene Kühlsystem mit Kühlwasserzufluß, Kühlwasserabfluß sowie Kühlwasserpumpe ist entsprechend ausgelegt, was aufwendig ist und insbesondere dann stört, wenn die Vorrichtung in einem oberirdischen oder unterirdischen Abbaufeld von Kohle mit installierten Förderbändern, die der Reparatur oder des Endlosmachens bedürfen, eingesetzt werden muß. In the (from practice) known devices of the described The type and intended use of the cooling medium is water. It flows through the cooling channels and absorbs the heat to be dissipated in the liquid state as sensible heat. Around to achieve a short-term cooling, as is particularly the case with conveyor belts Plastic is sought, a large amount of cooling water is required. The entire connected cooling system with cooling water inflow, cooling water drain and cooling water pump is designed accordingly, which is expensive and particularly annoying when the device in an above-ground or underground coal mining field installed conveyor belts that need to be repaired or made endless, must be used. Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung einfacher und wirksamer zu kühlen. The invention is based on the object of a generic device easier and more effective to cool. Zur Lösung dieser Aufgabe lehrt die Erfindung, daß die Kühlkanäle zumindest einseitig (d. h. zumindest einendig) offen als Kanäle einer Verdampfungskühlung ausgeführt sind und in die offenen Kühlkanäle eine Zuführleitung für Verdampfungswasser eingeführt ist. To solve this problem, the invention teaches that the cooling channels open at least on one side (i.e. at least one end) as channels for evaporative cooling are executed and in the open cooling channels a feed line for evaporation water is introduced. Zumindest einseitig offen heißt, daß die Kanäle zumindest an einer Seite offen sind. Sie können aber auch beidseitig offen oder in ihrer abdeckenden Kanalwandung Bohrungen aufweisen, die mit der Atmosphäre kommunizieren und es ebenso wie ein offenes Ende oder wie die offenen Enden zulassen, daß bei der Verdampfungskühlung entstehender Dampf in die Atmosphäre entweicht. - Die Erfindung nutzt die Tatsache, daß für die Verdampfung von Wasser in erheblichem Maße Umwandlungswärme erforderlich ist, die bei einer erfindungsgemäßen Vorrichtung den Pressenplatten und dem Gut entzogen wird, was kurzzeitig eine sehr wirksame Kühlung ermöglicht.Open at least on one side means that the channels at least on one Side are open. But they can also be open on both sides or in their covering Canal wall Have holes that communicate with the atmosphere and it just like a open end or like the open ends allow in evaporative cooling resulting steam escapes into the atmosphere. - The invention takes advantage of the fact that a considerable amount of heat of conversion is required for the evaporation of water is that in a device according to the invention, the press plates and the material is withdrawn, which briefly enables very effective cooling. Dabei reichen sehr geringe Kühlwassermengen aus, nämlich nur etwa 0,2% der bei flüssiger Kühlung erforderlichen Kühlwassermenge. Der entstehende Dampf kann in die Atmosphäre entweichen, da die Kühlkanäle in der beschriebenen Weise offen sind.Very small amounts of cooling water are sufficient, namely only approximately 0.2% of the amount of cooling water required for liquid cooling. The resulting steam can escape into the atmosphere, as the cooling channels in the manner described are open. Darin liegt keine Umweltbelastung, da nur reiner Wasserdampf in die Atmosphäre abgegeben wird.There is no environmental impact in this, as only pure water vapor enters the Atmosphere is given off. Im einzelnen bestehen im Rahmen der Erfindung verschiedene Möglichkeiten der weiteren Ausbildung und Gestaltung. So ist eine bevorzugte Ausführungsform der Erfindung dadurch gekennzeichnet, daß die Zuführleitungen sich über die gesamte Länge der Kühlkanäle erstrecken und über ihre Länge verteilt Kühlwasseraustrittsöffnungen aufweisen. Als Zuführleitungen können Schläuche eingesetzt werden, die die Temperatur der Pressenplatten aufnehmen, es kann aber auch mit Rohren gearbeitet werden. Jedenfalls empfiehlt es sich, in die Zuführleitungen eine Abschlußleitung anzuschließen, die ein Dosierventil aufweist. In particular, there are various possibilities within the scope of the invention further training and design. So a preferred embodiment is the Invention characterized in that the supply lines extend over the entire Extend the length of the cooling channels and cooling water outlet openings distributed over their length exhibit. Hoses can be used as feed lines to control the temperature the press plates, but you can also work with pipes. In any case it is advisable to connect a termination line to the supply lines, which has a metering valve. Damit können die Verdampfungswassermenge und folglich die Kühlleistung reguliert werden. Das Dosierventil kann in einen Regelkreis integriert sein.This allows the amount of evaporation water and consequently the cooling capacity be regulated. The metering valve can be integrated into a control circuit. Bei einer erfindungsgemäßen Vorrichtung können die Pressenplatten Heizkanäle und Kühlkanäle in abwechselnder Folge aufweisen. Es besteht aber auch die Möglichkeit, die Pressenplatten als Doppelplatten mit einerseits Heizkanälen und andererseits Kühlkanälen in unterschiedlichen Etagen auszuführen. Dazu können zwei Pressenplatten aufeinandergelegt, dazu kann aber auch eine Pressenplatte in unterschiedlichen Etagen mit einerseits Heizkanälen und andererseits Kühlkanälen versehen sein. In a device according to the invention, the press plates Have heating channels and cooling channels in an alternating sequence. But it also exists the possibility of using the press plates as double plates with heating channels on the one hand and on the other hand to run cooling channels in different floors. You can do this two press plates placed one on top of the other, but a press plate in different floors with heating ducts on the one hand and cooling ducts on the other be provided. Die erreichten Vorteile sind darin zu sehen, daß bei einer erfindungsgemäßen Vorrichtung eine sehr wirksame Kühlung wesentlich einfacher verwirklicht werden kann, als im Rahmen der bekannten Maßnahmen mit Flüssigkühlung. Wird die erfindungsgemäße Vorrichtung z. B. in einem oberirdischen oder unterirdischen Abbaufeld von Kohle eingesetzt, so kann das Kühlwasser für die Kühlung im allgemeinen in einem Kanister bereit gestellt werden, so daß besondere Anschlußleitungen an eine Brauchwasserversorgung nicht erforderlich sind. The advantages achieved are to be seen in the fact that in an inventive Device a very effective cooling can be realized much more easily can, as in the context of the known measures with liquid cooling. If the invention Device z. B. in an above-ground or underground coal mining field used, the cooling water for cooling can generally be in a canister are made available so that special connection lines to a service water supply are not required. Im folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung ausführlicher erläutert.
