Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Reinigen von Behältern der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a device for cleaning containers of the type explained in the preamble of claim 1.
Die Erfindung findet besondere Anwendung bei der Reinigung von Flaschen oder anderen Getränkebehältern vor ihrer Befüllung mit Getränken. An den Reinigungsprozess für derartige Behälter werden hohe Anforderungen gestellt. Zum einen sollten die Behälter optisch sauber und glänzend sein, zum anderen sollten die Behälter vor der Befüllung in einen hygienisch einwandfreien Zustand gebracht werden, um eine Kontamination des Getränkes mit Mikroorganismen so weit wie möglich zu vermeiden. Beim Einsatz von Mehrwegbehältern muss weiterhin das Etikett oder dergleichen Kennzeichnungsmittel und die Klebstoffe zu ihrer Befestigung rückstandsfrei entfernt werden. Dieser anspruchsvolle Reinigungsprozess wird in einer Vielzahl von Reinigungsstationen durchgeführt, die der Behälter nacheinander durchlaufen muss. Derartige Reinigungsstationen enthalten beispielsweise Laugebehandlungen unterschiedlicher Ausgestaltung, und anschließend Spülbehandlungen, in denen lediglich Wasser als Reinigungsflüssigkeit verwendet wird. Üblicherweise wird zunächst mit warmem und anschließend mit kaltem Wasser gespült, wobei sich am Schluss noch eine Frischwasserspülung anschließt, die auch die letzten Verunreinigungen entfernt und den Behälter ggf. kühlt. Dementsprechend groß ist der Verbrauch an Reinigungsflüssigkeit, insbesondere der Wasserverbrauch, und Energie. Es hat deshalb nicht an Versuchen gefehlt, diese Ressourcen einzusparen. So hat man bisher das in Auffangbehältern aufgefangene Wasser der letzten Reinigungsstufe(n) kaskadenartig über ein Überlaufblech in Auffangbehälter vorangegangener Reinigungsstationen rückgeführt, so dass das relativ gering verschmutzte Wasser aus den letzten Reinigungsstationen die Reinigungsflüssigkeiten in den stromaufwärts liegenden Reinigungsstationen verdünnt. Auf diese Weise wird das relativ gesehen saubere Reinigungsmittel einer nachfolgenden Reinigungsstation nochmals in einer vorangegangenen Reinigungsstation verwendet, wo es eine weitere Schmutzfracht (Lauge) aufnehmen kann. Die bekannte Konstruktion wurde bisher für ein Spülen der Behälter eingesetzt, nachdem sie diverse Laugenbehandlungen durchlaufen haben. Das Prinzip der Wasserrückführung wurde sowohl zwischen einem nachfolgenden Kaltwasser-Auffangbecken und einem vorangegangenen Warmwasser-Auffangbecken als auch zwischen einem nachfolgenden Warmwasserbecken und einem zweiten vorangegangenen Warmwasserbecken eingesetzt. Nachteilig an dieser Ausgestaltung ist der relativ geringe Verdünnungsgrad, den das rückgeführte Wasser auf den stärker schmutzbefrachteten Wasservorrat im Auffangbehälter der vorangegangenen Reinigungsstation ausübt, da das rückgeführte Wasser immer mit dem gesamten Wasservolumen der vorangegangenen Reinigungsstation vermischt wird.The invention finds particular application in the cleaning of bottles or other beverage containers prior to their filling with beverages. At the cleaning process for such containers high demands are made. On the one hand, the containers should be visually clean and shiny, on the other hand, the containers should be brought to a hygienically perfect condition before filling in order to avoid contamination of the beverage with microorganisms as far as possible. When reusable containers are used, the label or the like marking agent and the adhesives for their attachment must also be removed without residue. This demanding cleaning process is carried out in a variety of cleaning stations, which must pass through the container in succession. Such cleaning stations include, for example, Laugebehandlungen different design, and then rinsing treatments in which only water is used as a cleaning liquid. Usually, first with warm and then rinsed with cold water, which is followed by a fresh water flush, which also removes the last impurities and possibly cools the container. Accordingly, the consumption of cleaning liquid, in particular water consumption, and energy is correspondingly high. There has been no lack of attempts to save these resources. So far, the trapped in collecting containers water of the last purification stage (s) has been cascaded over an overflow plate in collection container preceding cleaning stations, so that the relatively low polluted water from the last cleaning stations dilutes the cleaning liquids in the upstream cleaning stations. In this way, the relatively clean cleaner of a subsequent cleaning station is used again in a previous cleaning station, where it can accommodate a further pollution load (liquor). The known construction has hitherto been used for rinsing the containers after they have undergone various lye treatments. The principle of water recycling was both between a subsequent cold water catch basin and a previous hot water catch basin and between a subsequent hot water tank and a second previous Hot water tank used. A disadvantage of this embodiment is the relatively low degree of dilution that the recycled water exerts on the more heavily polluted water supply in the collecting container of the previous cleaning station, since the recirculated water is always mixed with the entire volume of water of the previous cleaning station.
Eine derart bekannte Vorrichtung ist in der
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Reinigen von Behältern bereitzustellen, die eine effektivere Ausnutzung der eingesetzten Reinigungsflüssigkeit bietet.The invention has for its object to provide a device for cleaning containers, which offers a more effective use of the cleaning fluid used.
Die Aufgabe wird durch die im Anspruch 1 beschriebene Vorrichtung und durch das im Anspruch 8 beschriebene Verfahren gelöst.The object is achieved by the device described in claim 1 and by the method described in
Die erfindungsgemäße Rückführung der "saubereren" Reinigungsflüssigkeit eines nachfolgenden Reinigungsvorgangs direkt in die Zufuhrleitung zum Spritzen der Behälter in einem vorherigen Reinigungsvorgang führt zu einem wesentlich stärkeren Verdünnungsgrad der Reinigungsflüssigkeit, da die Volumenmengen in der Zufuhrleitung wesentlich geringer sind als es der gesamten im Umlauf befindlichen Menge an Reinigungsflüssigkeit in dieser Reinigungsstation entspricht; d. h. die zum Abspritzen der Behälter verwendete Reinigungsflüssigkeit im vorangegangenen Reinigungsprozess ist immer "sauberer" als die in dieser Reinigungsstation umgewälzte Reinigungsflüssigkeit. Dadurch kann z. B. die aus einer vorangegangenen Laugebehandlung verbliebene Alkalität besser abgebaut und die Behälter nach einer Warmwasserbehandlung effektiver gekühlt werden.The recycling of the "cleaner" cleaning liquid of a subsequent cleaning process according to the invention directly into the supply line for spraying the containers in a previous cleaning process leads to a much greater degree of dilution of the cleaning liquid, since the volumes in the supply line are substantially less than the total amount circulating Cleaning fluid in this cleaning station corresponds; d. H. the cleaning liquid used for spraying the containers in the previous cleaning process is always "cleaner" than the cleaning liquid circulated in this cleaning station. As a result, z. B. the remaining from a previous leaching treatment alkalinity degraded better and the containers are cooled more effectively after a hot water treatment.
Dies betrifft besonders Reinigungsstationen, die einen Auffangbehälter für benutzte Reinigungsflüssigkeit aufweisen, aus der die Reinigungsflüssigkeit zum Abspritzen der Behälter kontinuierlich entnommen wird und in der die Reinigungsflüssigkeit nach dem Abspritzen wieder gesammelt wird. Diese Auffangbehälter haben ein relativ großes Aufnahmevolumen, so dass sich bei der erfindungsgemäßen Rückführung in die Zufuhrleitung der prozentuale Anteil der verdünnenden, sauberen Reinigungsflüssigkeit aus dem nachfolgenden Reinigungsprozess in Bezug auf den Volumenanteil der im vorherigen Reinigungsprozess umgewälzten Reinigungsflüssigkeit besonders stark erhöht.This particularly relates to cleaning stations, which have a collecting container for used cleaning liquid from which the cleaning liquid for spraying the container is removed continuously and in which the cleaning liquid is collected again after the spraying. These collecting containers have a relatively large receiving volume, so that the proportion of the diluting, clean cleaning liquid from the subsequent cleaning process with respect to the volume fraction of the cleaning liquid circulated in the previous cleaning process is increased particularly strongly during the inventive return to the supply line.
Die Rückführleitung mündet bevorzugt über einen Überlauf, der eine Sammelwirkung entfaltet.The return line preferably opens via an overflow, which unfolds a collecting effect.
Durch die stromaufwärts der Pumpe einmündende Rückführleitung wird eine gleichmäßige Vermischung sichergestellt.The return line leading to the pump ensures uniform mixing.
Ein Filter stellt sicher, dass Grobschmutz aus dem Auffangbehälter abgefiltert werden kann.A filter ensures that coarse dirt can be filtered out of the collecting container.
Die Zufuhr von Frischwasser zum Ersatz des durch die Behälter aus der Reinigungsanlage geschleppten Reinigungsmittelanteils bzw. sonstiger Verluste erfolgt bevorzugt wiederum über die Rückführung von bereits benutzter Reinigungsflüssigkeit aus dem letzten Spülgang.The supply of fresh water to replace the carried by the container from the cleaning equipment detergent or other losses is preferably carried out again on the return of already used cleaning liquid from the last rinse.
Die Erfindung ist in jedem Reinigungssystem anwendbar, bei dem mehrere Reinigungsstationen vorgesehen sind, die die gleiche Art von Reinigungsflüssigkeit einsetzen.The invention is applicable in any cleaning system in which a plurality of cleaning stations are provided, which use the same type of cleaning liquid.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der einzigen Zeichnung näher erläutert, die in stark schematisierter Darstellung ein Schema der erfindungsgemäßen Vorrichtung zeigt.An embodiment of the invention will be explained in more detail with reference to the single drawing, which shows in a highly schematic representation of a scheme of the device according to the invention.

Beim Betrieb der erfindungsgemäßen Vorrichtung 1 werden die Behälter 2 durch die Vorrichtung 1 geschleust, so dass sie zunächst in die erste Reinigungsstation 4.1 eintreten und dort mit Reinigungsflüssigkeit aus dem Auffangbehälter 5.1 behandelt werden. Dann treten die Behälter nach und nach durch die zweite, dritte und vierte Reinigungsstation 4.2 bis 4.4 hindurch, in denen sie jeweils mit dem Reinigungsmittel aus dem zugeordneten Auffangbehälter 5.2 bis 5.4 behandelt werden, das jeweils über die zugeordnete Zufuhrleitung 6.2 bis 6.4 der zugeordneten Spritzeinrichtung 7.2 bis 7.4 (bewirkt durch die Pumpen 10.2 bis 10.4) zugeführt wird. Anschließend gelangen die Behälter 2 in die im dargestellten Ausführungsbeispiel letzte Reinigungsstation 4.5, in der sie mit einem Schwall frisch zugeführten Reinigungsmittel, im dargestellten Ausführungsbeispiel mit einem Frischwasserschwall über die Zufuhrleitung 6.5 und die Düse 9 klargespült werden. Das hier von den Behältern 2 wieder abtropfende Reinigungsmittel gelangt über die Rinne 13, die Mündung 14.1 und die Rückführleitung 12.1 in die Zuführleitung 6.4 der vorangegangenen Reinigungsstation 4.4 und verdünnt das dort durch die Pumpe 10.4 aus dem Auffangbehälter 5.4 abgesaugte Reinigungsmittel. Das Reinigungsmittel läuft über die Behälter 2 und tropft wieder in den Auffangbehälter 5.4. Steigt der Pegel im Auffangbehälter 5.4 der vierten Reinigungsstation 4.4 bis zum Überlauf 14.2 an, so wird das Reinigungsmittel aus dem Auffangbehälter 5.4 über die Rückführleitung 12.2 in die Zufuhrleitung 6.3 der vorangegangenen Reinigungsstation 4.3 rückgeführt und gelangt dort in den Reinigungsmittelstrom, der durch die Pumpe 10.3 aus dem Auffangbehälter 5.3 der dritten Reinigungsstation 14.3 abgesaugt wird. Das auf diese Weise verdünnte Reinigungsmittel gelangt dann in die Spritzeinrichtung 7.3 und wird über die Behälter 2 geleitet. Anschließend tropft die Reinigungsflüssigkeit wieder in den Auffangbehälter 5.3.During operation of the device 1 according to the invention, the containers 2 are passed through the device 1, so that they first enter the first cleaning station 4.1 and are treated there with cleaning liquid from the collecting container 5.1. Then, the containers gradually pass through the second, third and fourth cleaning stations 4.2 to 4.4, in which they are each treated with the cleaning agent from the associated collecting container 5.2 to 5.4, respectively via the associated supply line 6.2 to 6.4 of the associated sprayer 7.2 to 7.4 (effected by the pumps 10.2 to 10.4) is supplied. Subsequently, the containers 2 reach the cleaning station 4.5 in the illustrated embodiment, in which they are rinsed clean with a surge of freshly supplied detergent, in the illustrated embodiment with a fresh water surge on the supply line 6.5 and the
Wird im Auffangbehälter 5.3 der vorgegebene Höchststand erreicht, so gelangt das Reinigungsmittel aus dem Auffangbehälter 5.3 in die Rückführleitung 12.3 und wird von dieser in die Zufuhrleitung 6.2 der zweiten, vorangegangenen Reinigungsstation 4.2 eingespeist, gelangt dort in den Reinigungsmittelstrom, der durch die Pumpe 10.2 aus dem Auffangbehälter 5.2 der zweiten Reinigungsstation 14.2 abgesaugt wird und dann in die Spritzeinrichtung 7.2 und wird über die Behälter 2 geleitet. Anschließend tropft die Reinigungsflüssigkeit wieder in den Auffangbehälter 5.2. Wird der Pegel im zweiten Auffangbehälter 4.2 überschritten, kann Reinigungsmittel über den Überlauf 14.4 und die Leitung 15 abgezogen werden.If the predetermined maximum level is reached in the collecting container 5.3, the cleaning agent passes from the collecting container 5.3 in the return line 12.3 and is fed by this in the supply line 6.2 of the second, previous cleaning station 4.2, where it passes into the detergent stream, by the pump 10.2 from the Collecting container 5.2 of the second cleaning station 14.2 is sucked off and then into the sprayer 7.2 and is passed through the container 2. Then the cleaning liquid drips back into the collecting container 5.2. If the level in the second collecting container 4.2 is exceeded, cleaning agent can be removed via the overflow 14.4 and the
Da das Volumen der Zufuhrleitung 6 wesentlich geringer ist als das Volumen des zugeordneten Auffangbehälters 5, kann durch die hier einmündende Rückführleitung eine wesentlich effektivere Vermischung bzw. Verdünnung mit einem höheren Verhältnisfaktor stattfinden, als dies beispielsweise der Fall wäre, wenn zwischen den Auffangbehältern untereinander ein Überlauf bestehen würde. Da normalerweise das Reinigungsmittel aus der nachfolgenden Reinigungsstufe nicht so stark verschmutzt bzw. nicht so stark mit der Reinigungslauge belastet ist wie das Reinigungsmittel aus der vorangegangenen Reinigungsstation, wird durch die Rückführung über die Rückführleitung eine Aufbesserung, d.h. Verdünnung, der Reinigungsflüssigkeit der vorangegangenen Reinigungsstufe erreicht.Since the volume of the supply line 6 is substantially smaller than the volume of the associated
Werden die Auffangbehälter 5 und die Rinne 13, wie in
Im praktischen Versuch wurden Mischungsverhältnisse von 1 : 5, d.h. ein Teil "bessere" Reinigungsflüssigkeit aus einer nachfolgenden Reinigungsstufe auf fünf Teile der von der Pumpe 10 angesaugten Reinigungsflüssigkeit einer vorangegangenen Reinigungsstufe, erreicht.In practical experiment, mixing ratios of 1: 5, i. a part of "better" cleaning liquid from a subsequent cleaning stage on five parts of sucked by the
Praktische Versuche wurden mit folgenden Betriebsparametern durchgeführt:
Es wurde festgestellt, dass durch die erfindungsgemäße Ausgestaltung die Behälter besser gekühlt und der Alkalitätsabbau optimiert wurde. Eine überschlägige Berechnung mittels Wärmemengenberechnung ergibt eine Reduzierung der Spritzungstemperatur um ca. 2 °C. Die Behälter wurden dadurch mit einer kälteren und weniger alkalischen Flüssigkeit ausgespritzt.It was found that the container was cooled better and the degradation of alkalinity was optimized by the inventive design. An approximate calculation by means of heat quantity calculation results in a reduction of the spraying temperature by approx. 2 ° C. The containers were thereby ejected with a colder and less alkaline liquid.
In Abwandlung des beschriebenen und gezeichneten Ausführungsbeispiels kann die Erfindung auch bei anderen Reinigungseinrichtungen eingesetzt werden, bei denen Reinigungsflüssigkeit optimal ausgenutzt werden soll. Je nach Behälterart und Reinigungsaufgabe können andere Düsenanordnungen oder andere Düsenkombinationen oder andere Konstruktionen von Spritzeinrichtungen vorgesehen sein.In a modification of the described and illustrated embodiment, the invention can also be used in other cleaning devices in which cleaning liquid should be optimally utilized. Depending on the container type and cleaning task, other nozzle arrangements or other nozzle combinations or other constructions of injection devices may be provided.
