Description
Die Erfindung bezieht sich auf eine Flaschenreinigungsanlage der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a bottle cleaning system explained in the preamble of
Reinigungs- und/oder Entkeimungsanlagen für Gegenstände, insbesondere für Mehrwegflaschen und/oder andere Gefäße, arbeiten gewöhnlich mit mehreren Behandlungsstufen, in denen die Flaschen mit einer Lauge oder einer anderen Flüssigkeit bei unterschiedlichen Temperaturen behandelt werden, um beispielsweise Thermospannungen zu reduzieren oder Energie zu sparen, wenn unterschiedliche Reinigungsvorgänge bei unterschiedlichen Temperaturen optimal ablaufen. Bislang wurde für jede Behandlungsstufe eine eigene Heizung vorgesehen, wobei dafür bevorzugt dampfbeheizte Wärmetauscher eingesetzt wurden. Eine vorbestimmte Flüssigkeitsmenge der jeweiligen Behandlungsstufe wurde laufend oder im Intervall aus der Behandlungsstufe abgezogen und über den Wärmetauscher bei Bedarf nacherhitzt. Es ist weiterhin bekannt, zusätzlich für einen gewissen Wärmeaustausch zwischen der Behandlungsstufe mit der höchsten Temperatur und der oder einer der Behandlungsstufen mit geringerer Temperatur zu sorgen, was ebenfalls über einen zusätzlichen Wärmetauscher geschehen kann. Die bekannte Vorrichtung ist somit relativ geräteaufwendig aufgebaut.Articles cleaning and / or sanitizing equipment, especially for refillable bottles and / or other vessels, usually operate with multiple treatment stages in which the bottles are treated with a caustic or other liquid at different temperatures to reduce, for example, thermoelectric voltages or save energy if different cleaning processes at optimal temperatures run optimally. So far, a separate heating was provided for each treatment stage, preferably steam-heated heat exchangers were used for this purpose. A predetermined amount of liquid of the respective treatment stage was withdrawn continuously or at intervals from the treatment stage and reheated via the heat exchanger, if necessary. It is also known to additionally provide for a certain heat exchange between the treatment stage with the highest temperature and the one or the treatment stages at a lower temperature, which can also be done via an additional heat exchanger.

Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in
Die vorliegende Erfindung beruht auf der Erkenntnis, dass es ausreichend ist, nur eine der Behandlungsstufen durch einen konstruktiv aufwendigen, z.B. dampfbeheizten Wärmetauscher zu erwärmen, während die weiteren Behandlungsstufen, sofern sie bei der gleichen oder bei einer geringeren Temperatur wie die erste Behandlungsstufe arbeiten, durch die Flüssigkeit aus der ersten Behandlungsstufe erwärmt werden.

Die Bypassleitung 11 ist mit einem Bypassventil 12 und einem Differenzdruck-Manometer 13 verbunden, über das die Aufheizleistung eingestellt werden kann. Weiterhin ist ein zweites Differenzdruck-Manometer 14 vorgesehen, über das der Druckverlust des dampfbeheizten Wärmetauschers 7 gemessen werden kann.The emerging from the heat exchanger 7 line 5 leads to a
Die erste Behandlungsstufe 2 enthält weiterhin einen Nebenkreislauf 2.2, der eine Leitung 15 enthält, die abwärts der Pumpe 6 aus dem Hauptkreislauf 2.1 abzweigt und zurück in die erste Behandlungsstufe 2 führt. Dieser Nebenkreislauf 2.2 dient zur Versorgung von nicht dargestellten Spritzdüsen, die Lauge außen und gegebenenfalls auch innen an und in die Gegenstände bzw. Flaschen spritzen und somit die Reinigung mechanisch unterstützen.The first treatment stage 2 also contains a secondary circuit 2.2, which contains a
Auch die zweite Behandlungsstufe 3 enthält einen Haupt- und einen Nebenkreislauf 3.1 bzw. 3.2 für die Lauge. Der Hauptkreislauf 3.1 führt mit einer Leitung 16 aus der zweiten Behandlungsstufe 3 heraus, die über eine Pumpe 17 und ein Absperrventil 18 in den zweiten Wärmetauscher 10 führt und von dort über ein weiteres Absperrventil 19 zurück in die zweite Behandlungsstufe 3 gelangt. Der Hauptkreislauf 3.1 ist weiterhin mit einer Bypassleitung 20 versehen, in der sich ein Ventil 21 befindet, wobei die Bypassleitung 20 den Wärmetauscher 10 überbrückt.The
Der Nebenkreislauf 3.2 ist analog des Hauptkreislaufes 2.2 der ersten Behandlungsstufe 2 ausgebildet und enthält eine Leitung 22, die stromabwärts der Pumpe 17 jedoch vor dem Wärmetauscher 10 bzw. dem Absperrventil 18 aus der Leitung 16 abzweigt und zurück in die zweite Behandlungsstufe 3 zur Versorgung einer Spritzeinrichtung führt.The secondary circuit 3.2 is formed analogously to the main circuit 2.2 of the first treatment stage 2 and contains a
Auch die dritte Behandlungsstufe 4 weist einen Hauptkreislauf 4.1 und einen Nebenkreislauf 4.2 auf. Der Hauptkreislauf 4.1 weist eine Leitung auf, die mit einem ersten Leitungsstrang 23a aus der dritten Behandlungsstufe 4 ausmündet und über eine Pumpe 24 und ein Ventil 25 in den Hauptkreislauf 3.1 der zweiten Behandlungsstufe 3 an einer Stelle einmündet, die zwischen dem Ventil 18 und dem Wärmetauscher 10 liegt. Ein weiterer Leitungsstrang 23b mündet aus dem Hauptkreislauf 3.1 der zweiten Behandlungsstufe 3 an einer Stelle zwischen dem Ausgang des Wärmetauschers 10 und dem Ventil 19, wiederum über ein Ventil 26 aus und gelangt zurück in die dritte Behandlungsstufe 4. Auch hier ist eine Bypassleitung 27 mit einem Ventil 28 zur Überbrückung des Wärmetauschers 10 vorgesehen, wobei die Leitung 27 den Leitungsstrang 23a zwischen der Pumpe 24 und dem Ventil 25 mit dem Leitungsstrang 23b stromabwärts des Ventils 26 verbindet.The

Beim Betrieb der Vorrichtung 1, beispielsweise zum Reinigen von Flaschen, wird der Hauptkreislauf 2.1 der ersten Behandlungsstufe 2 und die Leistungsfähigkeit des dampfbeheizten, ersten Wärmetauschers 7 so eingestellt, dass die Temperatur des Laugenbades in der ersten Behandlungsstufe 2 auf die erforderliche Temperatur, beispielsweise 81°C, gebracht und gehalten wird. Dazu kann es gegebenenfalls notwendig sein, die Temperatur im Hauptkreislauf 2.1 über die Betriebstemperatur der ersten Behandlungsstufe 2 zu erhöhen, beispielsweise auf 95°C. Diese Temperatur wird dann gehalten, beispielsweise über eine Steuerung der Pumpleistung der Pumpe 6 und/oder über das Öffnen und Schließen der Bypassleitung 11. Dabei wird bevorzugt ein kontinuierlicher Volumenstrom aufrechterhalten, was über das Bypass-Ventil 12 gewährleistet wird, wobei je nach Auslegung/Leistungsbedarf zwischen 30 - 50 % des Umwälzvolumens der 1. Behandlungsstufe 2 über den ersten Wärmetauscher 7 geleitet und hinter den Wärmetauscher 7 mit der Lauge aus der Bypassleitung 11 vermischt wird, so dass eine Temperatur von 95°C gehalten werden kann.During operation of the
Gleichzeitig wird durch die Lauge der Behandlungsstufe 2 im Wärmetauscher 10 die Lauge der Behandlungsstufe 3 und die Lauge der Behandlungsstufe 4 erwärmt, wobei durch die erhöhte Temperatur im Hauptkreislauf 2.1 der ersten Behandlungsstufe die Lauge in den nachfolgenden Behandlungsstufen 3, 4 ebenfalls auf 81 bzw. 80°C bzw. jede darunter liegende Temperatur eingestellt werden kann. Dies erfolgt wiederum über die Leistung der Pumpen 17 bzw. 24, die Zuführregelung über die der Bypassleitungen 20, 27 und/oder die vollständige Abkopplung der Hauptkreisläufe 3.1 bzw. 4.1 vom Wärmetauscher 10 über die Ventile 18, 19, 25 und 26.At the same time, the liquor of the
In Abwandlung des beschriebenen und gezeichneten Ausführungsbeispiels können lediglich zwei oder mehr als drei Behandlungsstufen vorgesehen sein. Die Nebenkreisläufe können bei allen bzw. bei ausgewählten Behandlungsstufen entfallen, wenn eine mechanische Reinigung nicht mehr erforderlich ist.

Der erste Wärmetauscher kann außer durch Dampf selbstverständlich auch durch andere geeignete Medien wie z.B. Heißwasser oder Thermalöl beheizt werden.In a modification of the described and illustrated embodiment only two or more than three treatment stages may be provided. The secondary circuits can be omitted at all or at selected stages of treatment, if a mechanical cleaning is no longer required.
