Weiter umfasst die Flaschenreinigungsvorrichtung ein dem Warmwasserspritzbereich in der Flaschentransportrichtung nachgeordneten Frischwasserspritzbereich mit einer ersten Frischwasserspritzzone und einer zweiten Frischwasserspritzzone und einer unterhalb der ersten Frischwasserspritzzone und der zweiten Frischwasserspritzzone angeordneten Auffangvorrichtung. Zudem ist ein weiterer Überlauf zwischen der Auffangvorrichtung und dem Auffangbecken, dem die Auffangvorrichtung in der Flaschentransportrichtung nachgeordnet ist, vorgesehen, wobei der weitere Überlauf dazu ausgelegt ist, Wasser aus der Auffangvorrichtung heraus in die Wassertransportrichtung zu transportieren. Weiter umfasst die Flaschenreinigungsvorrichtung eine Wärmepumpe mit einem Verdampfer und einem Kondensator sowie einen geschlossenen Kühlkreislauf, in dem Kühlmedium von dem Verdampfer durch die Auffangvorrichtung, durch das oder die Auffangbecken zurück zu dem Verdampfer umläuft, wobei der Verdampfer dazu ausgelegt ist, das Kühlmedium in dem Kühlkreislauf abzukühlen. Zudem umfasst die Flaschenreinigungsvorrichtung einen Laugenkreislauf, in dem Lauge von dem Hauptlaugenbecken durch den Kondensator zurück in das Hauptlaugenbecken umläuft, wobei der Kondensator dazu ausgelegt ist, die Lauge zu erhitzen.The bottle cleaning device comprises a main caustic basin for receiving caustic and a hot water spraying area arranged downstream of the main caustic basin in a bottle transport direction. The hot water spraying area comprises a spraying zone and a collecting basin or, which is assigned to the spraying zone and is arranged below the spraying zone several spray zones arranged downstream in the bottle transport direction, each with an associated collecting basin arranged below the spray zone, with an overflow being provided between two collecting basins following one another in the bottle transport direction, which is designed to transport water out of the collecting basin in a water transport direction that the Bottle transport direction is opposite. The bottle cleaning device further comprises a fresh water spray area downstream of the hot water spray area in the bottle transport direction with a first fresh water spray zone and a second fresh water spray zone and a collecting device arranged below the first fresh water spray zone and the second fresh water spray zone. In addition, another overflow is provided between the collecting device and the collecting basin, after which the collecting device is arranged in the bottle transport direction, the further overflow being designed to transport water out of the collecting device in the water transport direction. The bottle cleaning device further comprises a heat pump with an evaporator and a condenser as well as a closed cooling circuit in which the cooling medium circulates from the evaporator through the collecting device, through the collecting basin (s) back to the evaporator, the evaporator being designed to convey the cooling medium in the cooling circuit to cool off. In addition, the bottle cleaning device comprises a caustic circuit in which caustic circulates from the main caustic basin through the condenser back into the main caustic basin, the condenser being designed to heat the caustic solution.

In dem Warmwasserspritzbereich kann eine Spritzzone mit einer Spritzwassertemperatur von 45 °C bis 65 °C vorgesehen sein. Sind mehrere Spritzzonen vorgesehen, so kann die Spritzwassertemperatur einer ersten Spritzzone in einem Bereich von 55 °C bis 60 °C liegen, insbesondere kann die Temperatur etwa 58 °C betragen, in einer zweiten Spritzzone in einem Bereich von 50 °C bis 55 °C liegen, insbesondere kann die Temperatur etwa 53 °C betragen, und in einer dritten Spritzzone in einem Bereich von 40 °C bis 45 °C, insbesondere kann die Temperatur 43 °C betragen. Bei den jeweiligen Spritzwassertemperaturen ist darauf zu achten, dass in den in der Flaschentransportrichtung aufeinanderfolgenden Spritzzonen die Spritzwassertemperatur abnimmt. In jeder der Spritzzonen kann mittels Düsen Wasser in die kopfüber transportierten Flaschen gespritzt werden, um eine Reinigung der Flaschen vorzunehmen.A spray zone with a spray water temperature of 45 ° C to 65 ° C can be provided in the hot water spray area. If several spray zones are provided, the spray water temperature of a first spray zone can be in a range from 55 ° C to 60 ° C, in particular the temperature can be around 58 ° C, in a second spray zone in a range from 50 ° C to 55 ° C In particular, the temperature can be about 53 ° C, and in a third spray zone in a range from 40 ° C to 45 ° C, in particular the temperature can be 43 ° C. With the respective spray water temperatures, it must be ensured that the spray water temperature decreases in the spray zones that follow one another in the bottle transport direction. In each of the spray zones, water can be sprayed into the bottles transported upside down by means of nozzles in order to clean the bottles.

Der Ausdruck "unterhalb angeordnet" bedeutet für den Warmwasserspritzbereich, dass das Auffangbecken sich in einer relativen Lage zu der Spritzzone befindet, so dass es durch die Düsen der Spritzzone ausgegebenes Wasser auffangen kann. Das in dem Auffangbecken aufgefangene Wasser sowie Wasser, das mittels eines Überlaufs eines in Flaschentransportrichtung nachfolgenden Auffangbeckens oder mittels des weiteren Überlaufs der in der Flaschentransportrichtung nachfolgenden Auffangvorrichtung in das Auffangbecken gelangt, wird derjenigen Spritzzone zugeführt, der das Auffangbecken zugeordnet ist. Ein der Spritzzone "zugeordnetes" Auffangbecken bedeutet, dass dieses Auffangbecken nur Wasser dieser Spritzzone auffängt. Somit kann das Auffangbecken oder können die Auffangbecken dafür vorgesehen sein, mittels Spritzdüsen ausgebrachtes Wasser aufzufangen und für nachfolgende Arbeitsprozesse zur Verfügung zu stellen. Dazu kann das in einem Auffangbecken aufgefangene Wasser jeweils über eine Zuleitung mit einer Pumpe den Spritzdüsen der jeweiligen Spritzzone zugeführt werden.The expression "arranged below" means for the hot water spraying area that the collecting basin is in a position relative to the spraying zone, so that it can collect water discharged through the nozzles of the spraying zone. The water collected in the collecting basin as well as water that reaches the collecting basin by means of an overflow of a collecting basin following in the bottle transport direction or by means of the further overflow of the collecting device following in the bottle transport direction is fed to the spray zone to which the collecting basin is assigned. A catch basin "assigned" to the spray zone means that this catch basin only catches water from this spray zone. The collecting basin or the collecting basins can thus be provided to collect water discharged by means of spray nozzles and to make it available for subsequent work processes. For this purpose, the water collected in a collecting basin can be fed to the spray nozzles of the respective spray zone via a feed line with a pump.

In dem Frischwasserspritzbereich sind die erste und die zweite Frischwasserspritzzone vorgesehen, wobei das Spritzwasser der ersten Frischwasserspritzzone eine Temperatur von etwa 35 °C und das Spritzwasser der zweiten Frischwasserspritzzone eine Temperatur von etwa 12 °C aufweisen kann. Für die zweite Frischwasserspritzzone kann reines Frischwasser verwendet werden, wohingegen für die erste Frischwasserspritzzone Wasser aus der Auffangvorrichtung verwendet werden kann.The first and second fresh water spray zones are provided in the fresh water spray area, the spray water of the first fresh water spray zone being at a temperature of around 35 ° C and the spray water of the second fresh water spray zone having a temperature of around 12 ° C. Pure fresh water can be used for the second fresh water spray zone, whereas water from the collecting device can be used for the first fresh water spray zone.

Der Ausdruck "unterhalb angeordnet" bedeutet für die Frischwasserspritzzone, dass die Auffangvorrichtung sich in einer relativen Lage zu der ersten und der zweiten Frischwasserspritzzone befindet, so dass sie durch die Düsen der ersten und der zweiten Frischwasserspritzzone ausgegebenes Wasser auffangen kann. Das in der Auffangvorrichtung aufgefangene Wasser kann der ersten Frischwasserspritzzone zugeführt werden. Somit kann die Auffangvorrichtung dafür vorgesehen sein, mittels Spritzdüsen ausgebrachtes Wasser aufzufangen und für nachfolgende Arbeitsprozesse zur Verfügung zu stellen. Dazu kann das in der Auffangvorrichtung aufgefangene Wasser über eine Zuleitung mit einer Pumpe den Spritzdüsen der ersten Frischwasserspritzzone zugeführt werden. Das Wasser kann hierbei neben Wasser Zusätze, wie beispielsweise Lauge, umfassen. Das Frischwasser enthält keine Zusätze.The term "arranged below" means for the fresh water spray zone that the collecting device is in a relative position to the first and the second fresh water spray zone so that it can collect water dispensed through the nozzles of the first and the second fresh water spray zone. The water collected in the collecting device can be fed to the first fresh water spray zone. Thus, the collecting device can be provided to collect water discharged by means of spray nozzles and to make it available for subsequent work processes. For this purpose, the water collected in the collecting device can be fed to the spray nozzles of the first fresh water spray zone via a feed line with a pump. In addition to water, the water can include additives such as, for example, lye. The fresh water does not contain any additives.

Die Ausdrücke "Überlauf" und "weiterer Überlauf" werden verwendet, um eine Unterscheidung zwischen einem Überlauf zwischen zwei Auffangbecken bzw. einem Überlauf zwischen der Auffangvorrichtung und einem Auffangbecken zu ermöglichen.The terms "overflow" and "further overflow" are used to enable a distinction to be made between an overflow between two collecting basins and an overflow between the collecting device and a collecting basin.

Die Flaschentransportrichtung kann von dem Hauptlaugenbecken zu dem Warmwasserspritzbereich und zu dem Frischwasserspritzbereich verlaufen. In der Transportrichtung gesehen, kann vor dem Hauptlaugenbecken ein Vorweichbecken angeordnet sein.The bottle transport direction can be from the main caustic basin to the hot water spray area and to the fresh water spray area. Seen in the direction of transport, a pre-soaking basin can be arranged in front of the main caustic basin.

Die Wassertransportrichtung ergibt sich aus dem Volumenstrom des Wassers, der mittels des weiteren Überlaufs aus der Auffangvorrichtung in ein Auffangbecken gelangt bzw. wenn mehrere Auffangbecken vorhanden sind, dann noch mittels eines Überlaufs zwischen zwei aufeinanderfolgenden Auffangbecken, von Auffangbecken zu Auffangbecken gelangt. Durch die Anordnung des weiteren Überlaufs und eines oder mehrerer Überläufe gelangt somit Wasser aus dem Frischwasserspritzbereich in den Warmwasserspritzbereich.The direction of water transport results from the volume flow of the water, which reaches a collecting basin by means of the further overflow from the collecting device or, if there are several collecting basins, then still passing from collecting basin to collecting basin by means of an overflow between two consecutive collecting basins. Through the Arrangement of the further overflow and one or more overflows thus passes water from the fresh water spray area into the hot water spray area.

In bekannten Flaschenreinigungsvorrichtungen werden die Flaschen kopfüber durch mehrere Spritzzonen geführt, in denen sie mit Wasser mit abnehmender Schmutzkonzentration und Temperatur innen ausgespritzt werden. Am Ende werden die Flaschen mit kaltem Frischwasser ausgespritzt, um eine gewünschte Abgabetemperatur der Flaschen und eine vollständige Entfernung von Laugen- und Tensidresten in den gereinigten Flaschen sicherzustellen. Häufig sind dafür drei Spritzbalken für Frischwasser vorgesehen. Bei optimierter Düsengröße und optimal eingestelltem Spritzdruck werden je Flasche etwa dreimal 50 ml Frischwasser eingesetzt. Für eine Einsparung von Frischwasser kann Spülwasser aus der letzten Frischwasserspritzung wieder aufbereitet und in der vorletzten Spritzung wieder eingesetzt werden. Meist wird der Bedarf für die Ersetzung von Frischwasser aus dem Überlauf aus dem Warmwasserbereich abgezogen, z.B. etwa 1/3 des Überlaufs, und vor der letzten Spritzung wieder eingesetzt. Eine weitere Reduzierung des Frischwassereinsatzes ist jedoch nicht möglich, da die erforderliche Rückkühlung der Flaschen nicht erreicht werden kann.In known bottle washing devices, the bottles are passed upside down through several spray zones in which they are sprayed with water with decreasing dirt concentration and temperature inside. At the end, the bottles are sprayed with cold fresh water in order to ensure the desired dispensing temperature of the bottles and complete removal of lye and surfactant residues in the cleaned bottles. Often three spray bars are provided for fresh water for this purpose. With an optimized nozzle size and optimally set spray pressure, around three times 50 ml of fresh water are used per bottle. To save fresh water, rinsing water from the last fresh water spray can be reprocessed and used again in the penultimate spray. Usually, the need for the replacement of fresh water from the overflow is subtracted from the hot water area, e.g. about 1/3 of the overflow, and used again before the last spray. However, a further reduction in the use of fresh water is not possible, since the required recooling of the bottles cannot be achieved.

Durch die in der erfindungsgemäßen Flaschenreinigungsvorrichtung verwendete aktive Rücckühlung ist es möglich, zwei Spritzrohre mit aufbereitetem Wasser zu versorgen. Um zu verhindern, dass es durch den reduzierten Wasserdurchsatz in der Wassertransportrichtung zu einem Anstieg der Konzentration von Lauge und Tensiden in den Spritzzonen kommt (Verschleppung von Lauge und Tensiden in der Flaschentransportrichtung), wird das Wasser für die Aufbereitung nicht dem Warmwasserspritzbereich entnommen, sondern dem Frischwasserspritzbereich.The active back cooling used in the bottle washing device according to the invention makes it possible to supply two spray tubes with treated water. In order to prevent the reduced water throughput in the water transport direction from increasing the concentration of lye and surfactants in the spray zones (carryover of lye and surfactants in the bottle transport direction), the water for the treatment is not taken from the hot water spray area, but from the Fresh water splash area.

Die Flaschenreinigungsvorrichtung kann als Einendmaschine oder als Zweiendmaschine (auch Doppelendmaschine genannt) ausgebildet sein. In einer Einendmaschine sind im Allgemeinen die Aufgabe- und Abnahmeöffnung für die Flaschen an der gleichen Seite der Flaschenreinigungsvorrichtung vorgesehen. In einer Zweiendmaschine hingegen sind im Allgemeinen die Aufgabe- und Abnahmeöffnung für die Flaschen an verschiedenen Seiten der Flaschenreinigungsvorrichtung vorgesehen.The bottle cleaning device can be designed as a single-end machine or as a two-end machine (also called a double-end machine). In a single-end machine, the infeed and unloading openings for the bottles are generally provided on the same side of the bottle washer. In a two-end machine, on the other hand, the loading and unloading openings for the bottles are generally provided on different sides of the bottle washing device.

Die Flaschenreinigungsvorrichtung kann weiter einen zusätzlichen Wärmetauscher umfassen, der dem Kondensator nachgeschaltet ist und der dazu ausgelegt ist, die Lauge zu erhitzen. Der zusätzliche Wärmetauscher kann mit Dampf oder Heißwasser beheizt werden. Wenn eine Erhitzung der Lauge durch den Kondensator nicht ausreichend ist, kann mit dem zusätzlichen Wärmetauscher die Lauge auf die gewünschte Temperatur gebracht werden.The bottle washing device can further comprise an additional heat exchanger which is connected downstream of the condenser and which is designed to heat the liquor. The additional heat exchanger can be heated with steam or hot water. If the heating of the liquor by the condenser is not sufficient, the liquor can be brought to the desired temperature with the additional heat exchanger.

Die Flaschenreinigungsvorrichtung kann weiter einen Kreislauf umfassen, der durch den Verdampfer, einen Verdichter, den Kondensator und eine Entspannungsdrossel zurück zu dem Verdampfer verläuft. Der Verdichter und die Entspannungsdrossel können Teile der Flaschenreinigungsvorrichtung sein.The bottle washer may further comprise a circuit that runs through the evaporator, a compressor, the condenser and an expansion throttle back to the evaporator. The compressor and the expansion throttle can be parts of the bottle washing device.

Die Flaschenreinigungsvorrichtung kann weiter ein Vorweichbecken umfassen. Die Temperatur der Vorweiche kann zwischen 35 °C - 45 °C betragen. Die Flaschen können in die Vorweiche des Vorweichbeckens eingetaucht werden, damit an den Flaschen anhaftender Schmutz gelöst wird.The bottle washing device can further comprise a presoak basin. The temperature of the pre-soak can be between 35 ° C - 45 ° C. The bottles can be immersed in the pre-soak in the pre-soaking basin so that dirt adhering to the bottles is loosened.

Zwischen dem Auffangbecken, das in der Flaschentransportrichtung dem Hauptlaugenbecken nachfolgt, und dem Vorweichbecken kann ein zusätzlicher Überlauf vorgesehen sein, der dazu ausgelegt ist, Wasser aus diesem Auffangbecken dem Vorweichbecken zuzuführen.An additional overflow can be provided between the collecting basin, which follows the main caustic basin in the bottle transport direction, and the pre-soaking basin, which is designed to supply water from this collecting basin to the pre-soaking basin.

Die Flaschenreinigungsvorrichtung kann eine Nachlaugenvorrichtung umfassen, die in der Flaschentransportrichtung dem Hauptlaugenbecken nachgeordnet ist.The bottle cleaning device can comprise a post-lye device which is arranged downstream of the main caustic basin in the bottle transport direction.

Die Nachlaugenvorrichtung kann ein Nachlaugenbecken umfassen. In das Nachlaugenbecken können die Flaschen eingetaucht werden, bevor sie in den Warmwasserspritzbereich gelangen. Die Nachlauge kann eine Temperatur in einem Bereich von 60 °C bis 65 °C aufweisen.The post-leach device may comprise a post-leach basin. The bottles can be immersed in the post-lye basin before they enter the hot water spray area. The post-caustic solution can have a temperature in a range from 60 ° C to 65 ° C.

Die Nachlaugenvorrichtung kann weiter eine Nachlaugenspritzzone umfassen, wobei das Nachlaugenbecken der Nachlaugenspritzzone zugeordnet und unterhalb dieser angeordnet ist. In der Nachlaugenspritzzone kann mittels Düse Wasser aus dem Nachlaugenbecken auf die Flaschen gespritzt werden. Der Ausdruck "unterhalb dieser angeordnet" bedeutet für den Nachlaugenspritzbereich, dass das Nachlaugenbecken sich in einer relativen Lage zu der Nachlaugenspritzzone befindet, so dass es durch die Düsen der Spritzzone ausgegebenes Wasser auffangen kann. Das in dem Nachlaugenbecken aufgefangene Wasser sowie Wasser, das mittels eines Überlaufs eines in Flaschentransportrichtung nachfolgenden Auffangbeckens in das Nachlaugenbecken gelangt, wird der Nachlaugenspritzzone zugeführt, der das Nachlaugenbecken zugeordnet ist. Ein der Nachlaugenspritzzone "zugeordnetes" Nachlaugenbecken bedeutet, dass dieses Nachlaugenbecken nur Wasser der Nachlaugenspritzzone auffängt. Das Wasser kann hierbei neben Wasser Zusätze, wie beispielsweise Lauge, umfassen.The post-lye device can further comprise a post-caustic spray zone, wherein the post-caustic basin is assigned to the post-caustic spray zone and is arranged below it. In the post-caustic spray zone, water from the post-caustic basin can be sprayed onto the bottles using a nozzle. The expression "arranged below this" means for the post-caustic spray area that the post-caustic basin is in a position relative to the post-caustic spray zone so that it can collect water dispensed through the nozzles of the spray zone. The water collected in the post-caustic basin and water that reaches the post-caustic basin by means of an overflow from a collecting basin following in the bottle transport direction is fed to the post-caustic spray zone to which the post-caustic basin is assigned. A post-caustic basin "assigned" to the post-caustic spray zone means that this post-caustic basin only catches water from the post-caustic spray zone. In addition to water, the water can include additives such as, for example, lye.

Zwischen dem Auffangbecken, das in der Flaschentransportrichtung dem Nachlaugenbecken nachfolgt, und dem Nachlaugenbecken kann ein weiterer Überlauf vorgesehen sein, der dazu ausgelegt ist, Wasser aus diesem Auffangbecken dem Nachlaugenbecken zuzuführen. Der Ausdruck "weiterer Überlauf" wird verwendet, um diesen Überlauf von anderen Überläufen der Flaschenreinigungsvorrichtung unterscheiden zu können.A further overflow can be provided between the collecting basin, which follows the secondary caustic basin in the bottle transport direction, and the secondary caustic basin, which is designed to supply water from this collecting basin to the secondary caustic basin. The The term "further overflow" is used to distinguish this overflow from other overflows of the bottle washer.

Zwischen dem Nachlaugenbecken und dem Vorweichbecken kann ein zusätzlicher Überlauf vorgesehen sein, der dazu ausgelegt ist, Nachlauge aus dem Nachlaugenbecken dem Vorweichbecken zuzuführen.An additional overflow can be provided between the post-caustic basin and the pre-soak basin, which is designed to supply post-caustic solution from the post-caustic basin to the pre-soak basin.

Die Flaschenreinigungsvorrichtung kann weiter eine Überschwallvorrichtung umfassen. Die Überschwallvorrichtung kann in der Flaschentransportrichtung nach dem Hauptlaugenbecken angeordnet sein. Nachdem die Flaschen aus dem Hauptlaugenbecken ausgetaucht sind, können durch die Überschwallung Etiketten bzw. Etikettenreste von den Flaschen gelöst werden.The bottle washing device can further comprise an overflow device. The overflow device can be arranged after the main caustic basin in the bottle transport direction. After the bottles have been removed from the main caustic basin, labels or label remnants can be detached from the bottles as a result of the overflow.

In einer ersten Ausführungsform kann die Auffangvorrichtung aus einem Becken bestehen. Das Spritzwasser der ersten und das Spritzwasser der zweiten Frischwasserspritzzone werden durch dieses eine Becken aufgefangen. D.h. für die erste und die zweite Frischwasserspritzzone ist ein einziges gemeinsames Becken vorgesehen. Das aufgefangene Wasser wird der ersten Frischwasserspritzzone zugeführt, wohingegen die zweite Frischwasserspritzzone mit reinem Frischwasser versorgt wird. Die erste Frischwasserspritzzone bringt, da ihr aufgefangenes Wasser aus der Auffangvorrichtung zugeführt wird, kein reines Frischwasser auf die Behälter auf; das durch die erste Frischwasserspritzzone ausgebrachte Wasser kann neben reinem Frischwasser, das durch die zweite Frischwasserspritzzone ausgebracht wird und in die Auffangvorrichtung gelangt, Zusätze, wie beispielsweise Lauge, umfassen. Die erste Frischwasserspritzzone stellt also eine sogenannte erste Frischwasserspritzzone dar, die nicht mit reinem Frischwasser versorgt wird.In a first embodiment, the collecting device can consist of a basin. The spray water from the first and the spray water from the second fresh water spray zone are caught by this one basin. This means that a single common basin is provided for the first and second fresh water spray zones. The collected water is fed to the first fresh water spray zone, whereas the second fresh water spray zone is supplied with pure fresh water. The first fresh water spray zone does not apply pure fresh water to the containers, since the water it collects is supplied from the collecting device; the water discharged through the first fresh water spray zone can include additives such as, for example, lye, in addition to pure fresh water which is discharged through the second fresh water spray zone and reaches the collecting device. The first fresh water spray zone thus represents a so-called first fresh water spray zone which is not supplied with pure fresh water.

In einer anderen Ausführungsform kann die Auffangvorrichtung aus einem ersten Becken und einem zweiten Becken bestehen, wobei das erste Becken unterhalb der ersten Frischwasserspritzzone und das zweite Becken unterhalb der zweiten Frischwasserspritzzone angeordnet sind und wobei der weitere Überlauf zwischen dem Auffangbecken, dem die Auffangvorrichtung in der Flaschentransportrichtung nachfolgt, und dem ersten Becken der Auffangvorrichtung vorgesehen ist. D.h. für die erste und die zweite Frischwasserspritzzone ist jeweils ein Becken vorgesehen. Durch die Verwendung der zwei Becken kann der Frischwasserbedarf der Flaschenreinigungsvorrichtung um bis zu 50 % reduziert werden.In another embodiment, the collecting device can consist of a first basin and a second basin, the first basin being arranged below the first fresh water spray zone and the second basin below the second fresh water spray zone and the further overflow being between the collecting basin to which the collecting device is located in the bottle transport direction follows, and the first basin of the collecting device is provided. This means that a basin is provided for each of the first and second fresh water spray zones. By using the two basins, the fresh water requirement of the bottle washer can be reduced by up to 50%.

Des Weiteren ist eine Wasseraufbereitungsvorrichtung vorgesehen, die dazu ausgelegt ist, Wasser der Auffangvorrichtung aufzubereiten und das aufbereitete Wasser der ersten Frischwasserspritzzone zuzuführen. Die Wasseraufbereitungsvorrichtung kann für eine Abscheidung von Partikeln, Neutralisation, Abscheidung von Tensiden und/oder Hygienisierung vorgesehen sein.Furthermore, a water treatment device is provided which is designed to treat water from the collecting device and to supply the treated water to the first fresh water spray zone. The water treatment device can be provided for separating particles, neutralizing, separating surfactants and / or sanitizing.

Figure 1 shows a block diagram of a first embodiment of a bottle washing device 1, which comprises a pre-soaking basin 2, a main caustic basin 3, an overflow device 4, a hot water spray area 41 with three different spray zones 5, 6, 7 and a fresh water spray area 42 with a first fresh water spray zone 8 and a second fresh water spray zone 9 .

Der Flaschenreinigungsvorrichtung 1 können zu reinigende Flaschen mittels eines Förderbands (nicht dargestellt) zugeführt werden. Diese Flaschen können in Flaschenzellen eines Flaschenträgers eingebracht werden, der dazu dient, die Flaschen durch die Flaschenreinigungsvorrichtung 1 zu transportieren. Die Flaschen werden dem Vorweichbecken 2 zugeführt und in die Vorweichlauge eingetaucht. In dem Vorweichbecken 2 können eine Vorreinigung zum Ablösen von anhaftendem Schmutz und ein Anwärmen der Flaschen erfolgen. Das Vorweichbecken 2 kann eine Temperatur von etwa 35°C - 45 °C aufweisen.Bottles to be cleaned can be fed to the bottle cleaning device 1 by means of a conveyor belt (not shown). These bottles can be placed in the bottle cells of a bottle carrier which is used to transport the bottles through the bottle cleaning device 1. The bottles are fed to the pre-soaking basin 2 and immersed in the pre-soaking liquor. In the pre-soaking basin 2, pre-cleaning to detach adhering dirt and heating of the bottles can take place. The pre-soaking basin 2 can have a temperature of approximately 35.degree. C.-45.degree.

Die Flaschen können dann aus dem Vorweichbecken 2 ausgetaucht werden, so dass die Flüssigkeit aus den Flaschen auslaufen kann. Dann werden die Flaschen dem Hauptlaugenbecken 3 zugeführt und in die Lauge eingetaucht. Die Lauge des Hauptlaugenbeckens 3 kann eine Temperatur von etwa 70 °C - 85 °C oder von etwa 78 °C - 80 °C aufweisen. Die im Hauptlaugenbecken 3 von den Flaschen abgelösten Etiketten werden durch eine aufgezwungene Strömung in dem Hauptlaugenbecken 3 gezielt abgeschieden und so aus der Lauge entfernt, um eine Verunreinigung klein zu halten. Eine Überschwallung der Flaschen mittels der Überschwallungsvorrichtung 4, nachdem die Flaschen aus dem Hauptlaugenbecken 3 ausgetaucht wurden, trägt auch dazu bei.The bottles can then be immersed from the pre-soaking basin 2 so that the liquid can run out of the bottles. Then the bottles are fed to the main caustic basin 3 and immersed in the caustic. The liquor in the main liquor basin 3 can have a temperature of approximately 70 ° C.-85 ° C. or approximately 78 ° C.-80 ° C. The labels detached from the bottles in the main caustic basin 3 are deliberately deposited by a forced flow in the main caustic basin 3 and thus removed from the caustic in order to keep contamination to a minimum. A flooding of the bottles by means of the flooding device 4 after the bottles have been removed from the main caustic basin 3 also contributes to this.

Dann können die Flaschen kopfüber die drei unterschiedlichen Spritzzonen 5, 6, 7 des Warmwasserspritzbereichs 41 durchlaufen, in denen mittels Spritzdüsen 10 das Flascheninnere ausgespritzt wird und/oder die Flaschen von außen überschüttet werden.Then the bottles can run upside down through the three different spray zones 5, 6, 7 of the hot water spray area 41, in which the inside of the bottle is sprayed out by means of spray nozzles 10 and / or the bottles are showered over from the outside.

Das Spritzwasser der ersten Spritzzone 5 kann eine Temperatur von 55 °C bis 60 °C aufweisen, insbesondere kann die Temperatur etwa 58 °C betragen, in der zweiten Spritzzone 6 kann die Temperatur des Spritzwassers in einem Bereich von 50 °C bis 55 °C liegen, insbesondere kann die Temperatur etwa 53 °C betragen, und in der dritten Spritzzone 7 kann die Spritzwassertemperatur in einem Bereich von 40 °C bis 45 °C liegen, insbesondere kann die Temperatur 43 °C betragen. Bei den jeweiligen Spritzwassertemperaturen ist darauf zu achten, dass in den drei in der Flaschentransportrichtung aufeinanderfolgenden Spritzzonen 5, 6, 7 die Spritzwassertemperatur abnimmt.The spray water of the first spray zone 5 can have a temperature of 55 ° C to 60 ° C, in particular the temperature can be around 58 ° C, in the second spray zone 6 the temperature of the spray water can be in a range from 50 ° C to 55 ° C In particular, the temperature can be about 53 ° C, and in the third spray zone 7 the spray water temperature can be in a range from 40 ° C to 45 ° C, in particular the temperature can be 43 ° C. For the respective spray water temperatures, it must be ensured that the spray water temperature decreases in the three spray zones 5, 6, 7 that follow one another in the bottle transport direction.

Danach durchlaufen die Flaschen kopfüber den Frischwasserspritzbereich 42, wobei das Spritzwasser der ersten Frischwasserspritzzone 8 eine Temperatur in einem Bereich von 32 °C bis 38 °C aufweist, insbesondere beträgt die Temperatur etwa 35 °C, und das Spritzwasser der zweiten Frischwasserspritzzone 9 eine Temperatur in einem Bereich von 10 °C bis 14 °C aufweist, insbesondere beträgt die Temperatur etwa 12 °C.The bottles then run through the fresh water spray area 42 upside down, the spray water of the first fresh water spray zone 8 having a temperature in a range from 32 ° C to 38 ° C, in particular the temperature is about 35 ° C, and the spray water of the second fresh water spray zone 9 has a temperature in has a range from 10 ° C to 14 ° C, in particular the temperature is about 12 ° C.

Durch die in den drei aufeinanderfolgenden Spritzzonen 5, 6, 7 und die in der ersten 8 und der zweiten Frischwasserspritzzone 9 abnehmende Temperatur des Spritzwassers erfolgt eine allmähliche Abkühlung der Flaschen. Dadurch werden Spannungen in dem Material der Flaschen minimiert, und die Flaschen sind derart auch auf eine nachfolgende Kaltabfüllung vorbereitet.As a result of the temperature of the spray water decreasing in the three successive spray zones 5, 6, 7 and in the first 8 and the second fresh water spray zone 9, the bottles are gradually cooled. This minimizes stresses in the material of the bottles, and the bottles are also prepared for subsequent cold filling.

Der ersten 5, der zweiten 6 und der dritten Spritzzone 7 sind entsprechend ein erstes 11, ein zweites 12 und ein drittes Auffangbecken 13 zugeordnet, wobei die Auffangbecken 11, 12, 13 jeweils unterhalb der entsprechenden Spritzzone 5, 6, 7 angeordnet sind. Die Auffangbecken 11, 12, 13 dienen dazu, das auf die Flaschen aufgebrachte Spritzwasser aufzufangen und für nachfolgende Abspritzprozesse zur Verfügung zu stellen. Dazu wird das aufgefangene Wasser jeweils über eine Zuleitung mit einer Pumpe 36 den Spritzdüsen 10 der jeweiligen Spritzzonen 5, 6, 7 zugeführt.The first 5, the second 6 and the third spray zone 7 are assigned a first 11, a second 12 and a third collecting basin 13, the collecting basins 11, 12, 13 each being arranged below the corresponding spray zone 5, 6, 7. The collecting basins 11, 12, 13 serve to collect the spray water applied to the bottles and make it available for subsequent spraying processes. For this purpose, the collected water is fed to the spray nozzles 10 of the respective spray zones 5, 6, 7 via a feed line with a pump 36.

Unterhalb der ersten 8 und der zweiten Frischwasserspritzzone 9 ist die Auffangvorrichtung 14, 15 angeordnet, die in der gezeigten Ausführungsform ein erstes Becken 14 und ein zweites Becken 15 umfasst, die dazu dienen, das auf die Flaschen aufgebrachte Spritzwasser aus der ersten 8 bzw. der zweiten Frischwasserspritzzone 9 aufzufangen. Aus dem ersten 14 und dem zweiten Becken 15 wird Wasser abgeleitet und zusammen einer Wasseraufbereitungsvorrichtung 16 zugeführt. Nach der Aufbereitung wird das Wasser als Spritzwasser in der ersten Frischwasserspritzzone 8 verwendet. In der Aufbereitung des Wassers können eine Abscheidung von Partikeln, eine Neutralisation, eine Abscheidung von Tensiden und/oder eine Hygienisierung erforderlich sein. Da das nichtaufbereitete Wasser dem Frischwasserspritzbereich entnommen wird, können möglicherweise die Partikelabscheidung und Hygienisierungsmaßnahmen entfallen, da in der zweiten Frischwasserspritzzone 9 die Flaschen mit Frischwasser klargespült werden.The collecting device 14, 15 is arranged below the first 8 and the second fresh water spray zone 9, which in the embodiment shown comprises a first basin 14 and a second basin 15, which serve to collect the spray water from the first 8 and the second basin 15, respectively second fresh water spray zone 9 to catch. Water is diverted from the first 14 and the second basin 15 and fed together to a water treatment device 16. After the treatment, the water is used as spray water in the first fresh water spray zone 8. Separation of particles, neutralization, separation of surfactants and / or sanitation may be necessary in the treatment of the water. As the untreated water goes to the fresh water splash area is removed, the particle separation and sanitation measures can possibly be omitted, since the bottles are rinsed clear with fresh water in the second fresh water spray zone 9.

In der Figur 1 ist der unterschiedlichen Menge von verwendetem Spritzwasser vereinfacht dadurch Rechnung getragen, dass in der ersten, zweiten und dritten Spritzzone jeweils drei Düsen 10 dargestellt sind, in der ersten Frischwasserspritzzone 8 nur zwei Düsen 10 und in der zweiten Frischwasserspritzzone 9 nur eine Düse.In the Figure 1 the different amounts of spray water used are taken into account in a simplified manner in that three nozzles 10 are shown in each of the first, second and third spray zones, only two nozzles 10 in the first fresh water spray zone 8 and only one nozzle in the second fresh water spray zone 9.

Aus dem Stand der Technik ist bekannt, eine Flaschenreinigungsmaschine kaskadenförmig aufzubauen, so dass eingespeistes Wasser von einem Auffangbecken zum nächsten Auffangbecken überlaufen und somit auch dort als Spritzwasser verwendet werden kann. Am Anfang einer derartigen Kaskade wird vorzugsweise Frischwasser eingespeist.It is known from the prior art to build up a bottle washing machine in a cascade shape, so that water fed in can overflow from one collecting basin to the next collecting basin and can thus also be used there as splash water. Fresh water is preferably fed in at the beginning of such a cascade.

In der hier beschriebenen Flaschenreinigungsvorrichtung 1 käme es in einem solchen kaskadenartigen Aufbau durch die beschriebene Reduktion der erforderlichen zugeführten Frischwassermenge in der zweiten Frischwasserspritzzone 9 ohne weitere Maßnahmen zu einem Temperaturanstieg in dem nachfolgenden ersten Becken 14 und den nachfolgenden Auffangbecken 11, 12, 13.In the bottle cleaning device 1 described here, in such a cascade-like structure, the described reduction in the required fresh water quantity supplied in the second fresh water spray zone 9 would lead to a temperature increase in the following first basin 14 and the following collecting basins 11, 12, 13 without further measures.

Die Flaschenreinigungsvorrichtung 1 weist einen Überlauf 17 zwischen dem ersten Becken 14 und dem dritten Auffangbecken 13 auf, einen Überlauf 18 zwischen dem dritten 13 und dem zweiten Auffangbecken 12 und einen Überlauf 19 zwischen dem zweiten 12 und dem ersten Auffangbecken 11. Der Überlauf 20 des ersten Auffangbeckens 11 ist mit dem Vorweichbecken 2 verbunden. In den einzelnen Überläufen 17, 18, 19, 20 können Filter für eine Filterung des überlaufenden Wassers vorgesehen sein. Die Überläufe 17, 18, 19, 20 können durch Überlaufventile 37 mit Wasser versorgt werden.The bottle washing device 1 has an overflow 17 between the first basin 14 and the third collecting basin 13, an overflow 18 between the third 13 and the second collecting basin 12 and an overflow 19 between the second 12 and the first collecting basin 11. The overflow 20 of the first The collecting basin 11 is connected to the pre-soaking basin 2. Filters for filtering the overflowing water can be provided in the individual overflows 17, 18, 19, 20. The overflows 17, 18, 19, 20 can be supplied with water through overflow valves 37.

Zwischen dem zweiten Becken 15 und dem ersten Becken 14 ist keine Verbindung durch einen Überlauf vorgesehen. Wie oben beschrieben wird jeweils Wasser aus dem ersten 14 und dem zweiten Becken 15 abgeleitet und zusammen der Wasseraufbereitungsvorrichtung 16 zugeführt.No connection through an overflow is provided between the second basin 15 and the first basin 14. As described above, water is diverted from the first 14 and the second basin 15 and fed together to the water treatment device 16.

Um dem Wärmeüberschuss, der durch die reduzierte Zufuhr von Frischwasser entsteht, Rechnung zu tragen, ist eine aktive Kühlung des Wassers in dem ersten Becken 14, dem dritten 13, dem zweiten 12 und dem ersten Auffangbecken 11 vorgesehen, die jeweils mit Wärmetauschern ausgestattet sind und hintereinander geschaltet von einem Kühlmedium in einem Kühlkreislauf 21 durchströmt werden. Mittels dieses Kühlkreislaufs 21 kann dem Wasser in dem ersten Becken 14, dem dritten 13, dem zweiten 12 und dem ersten Auffangbecken 11 die Wärmemenge entzogen werden, die zuvor durch den höheren Frischwasserdurchsatz des kaskadenförmigen Aufbaus einer Flaschenreinigungsmaschine des Stands der Technik abgeführt wurde.In order to take account of the excess heat that arises from the reduced supply of fresh water, active cooling of the water is provided in the first basin 14, the third 13, the second 12 and the first collecting basin 11, which are each equipped with heat exchangers and connected in series, a cooling medium in a cooling circuit 21 flows through it. By means of this cooling circuit 21, the water in the first basin 14, the third 13, the second 12 and the first collecting basin 11 can Amount of heat are withdrawn that was previously dissipated by the higher fresh water throughput of the cascade structure of a bottle washing machine of the prior art.

Das Kühlmedium in dem Kühlkreislauf 21 wird im Gleichstrom zur Fließrichtung des Wassers, d.h. der Wassertransportrichtung, das durch die Überläufe 17, 18, 19, 20 fließt, gefahren.The cooling medium in the cooling circuit 21 is driven in cocurrent to the flow direction of the water, i.e. the water transport direction flowing through the overflows 17, 18, 19, 20.

Das erwärmte Kühlmedium, das das erste Auffangbecken 11 verlässt, wird einem ersten Eingang 24 eines Verdampfers 22 einer Wärmepumpe 23 zugeführt. Das Kühlmedium kann eine Temperatur in einem Bereich von 57 °C bis 63 °C aufweisen, insbesondere kann die Temperatur etwa 60 °C betragen. In dem Verdampfer 22 wird das Kühlmedium zurückgekühlt und verlässt den Verdampfer 22 durch einen ersten Ausgang 25. Das Kühlmedium kann dann eine Temperatur in einem Bereich von 38 °C bis 42 °C aufweisen, insbesondere kann die Temperatur etwa 40 °C betragen. Von dort gelangt das Kühlmedium durch den Kühlkreislauf 21 zu dem ersten Becken 14, wo dann eine Kühlung des Wassers in dem ersten Becken 14 durch Wärmeaufnahme des Kühlmediums erfolgt. Dementsprechend erfolgt jeweils eine Abkühlung des Wassers in dem dritten 13, dem zweiten 12 und dem ersten Auffangbecken 11, durch die Kühlkreislauf 21 ebenfalls verläuft.The heated cooling medium that leaves the first collecting basin 11 is fed to a first inlet 24 of an evaporator 22 of a heat pump 23. The cooling medium can have a temperature in a range from 57.degree. C. to 63.degree. C., in particular the temperature can be approximately 60.degree. The cooling medium is cooled back in the evaporator 22 and leaves the evaporator 22 through a first outlet 25. The cooling medium can then have a temperature in a range from 38.degree. C. to 42.degree. C., in particular the temperature can be approximately 40.degree. From there, the cooling medium passes through the cooling circuit 21 to the first basin 14, where the water in the first basin 14 is then cooled by absorbing heat from the cooling medium. The water is correspondingly cooled in the third 13, the second 12 and the first collecting basin 11, through which the cooling circuit 21 also runs.

Als Kondensator 28 der Wärmepumpe 23 fungiert ein Laugenwärmetauscher, der einem zusätzlichen Wärmetauscher 29 des Hauptlaugenbeckens 3 vorgeschaltet ist. Aus dem Hauptlaugenbecken 3 wird Lauge einem ersten Eingang 30 des Kondensators 28 zugeführt, die durch das Eintauchen der Flaschenträger mit den Flaschenzellen und den Flaschen abgekühlt wird und dadurch kühler ist als die vorgesehene Temperatur des Hauptlaugenbeckens 3. Diese kühlere Lauge kann eine Temperatur von etwa 74 °C aufweisen. Im Kondensator 28 erfolgt eine Aufheizung der Lauge, die den Kondensator 28 durch einen ersten Ausgang 31 verlässt. Die aufgeheizte Lauge kann eine Temperatur von etwa 76 °C aufweisen. Wird durch die Aufheizung der Lauge in dem Kondensator 28 bereits die gewünschte Temperatur des Hauptlaugenbeckens 3 erreicht, so ist keine weitere Aufheizung der Lauge durch den zusätzlichen Wärmetauscher 29 in dem Hauptlaugenbecken 3 erforderlich. Der zusätzliche Wärmetauscher 29 kann mit Dampf oder Heißwasser beheizt werden. Wenn eine Erhitzung der Lauge für das Hauptlaugenbecken 3 durch den Kondensator 28 nicht ausreichend ist, kann mit dem zusätzlichen Wärmetauscher 29 die Lauge auf die gewünschte Temperatur gebracht werden.A lye heat exchanger, which is connected upstream of an additional heat exchanger 29 of the main caustic basin 3, functions as the condenser 28 of the heat pump 23. From the main caustic basin 3, caustic is supplied to a first inlet 30 of the condenser 28, which is cooled by the immersion of the bottle carriers with the bottle cells and the bottles and is therefore cooler than the intended temperature of the main caustic basin 3 ° C. The liquor is heated in the condenser 28 and leaves the condenser 28 through a first outlet 31. The heated liquor can have a temperature of about 76 ° C. If the desired temperature of the main caustic basin 3 is already reached by heating the caustic in the condenser 28, no further heating of the caustic by the additional heat exchanger 29 in the main caustic basin 3 is necessary. The additional heat exchanger 29 can be heated with steam or hot water. If the heating of the caustic solution for the main caustic basin 3 by the condenser 28 is not sufficient, the caustic solution can be brought to the desired temperature with the additional heat exchanger 29.

Die Lauge wird in dem Kondensator 28 durch Wärmeabgabe eines Mediums erhitzt, das durch einen zweiten Eingang 32 in den Kondensator gelangt und dort verflüssigt wird. Das Medium verlässt den Kondensator 28 durch einen zweiten Ausgang 33; dort kann das Medium eine Temperatur in einem Bereich von 78 °C bis 82 °C aufweisen, insbesondere kann die Temperatur etwa 80 °C betragen. Das Medium passiert eine Entspannungsdrossel 34 und gelangt durch einen zweiten Eingang 26 in den Verdampfer 22. Nach dem Passieren der Entspannungsdrossel kann das Medium eine Temperatur in einem Bereich von 33 °C bis 38 °C aufweisen, insbesondere kann die Temperatur etwa 35 °C betragen. Das Medium verlässt den Verdampfer 22 über einen zweiten Ausgang 27 und passiert einen Verdichter 35, bevor es über den zweiten Eingang 32 wieder in den Kondensator 28 gelangt.The lye is heated in the condenser 28 by the release of heat from a medium which enters the condenser through a second inlet 32 and is liquefied there. The medium leaves the condenser 28 through a second outlet 33; there the medium can have a temperature in a range from 78.degree. C. to 82.degree. C., in particular the temperature can be about 80.degree. The medium passes an expansion throttle 34 and arrives through a second inlet 26 into the evaporator 22. After passing the expansion throttle, the medium can have a temperature in a range from 33.degree. C. to 38.degree. C., in particular the temperature can be approximately 35.degree. The medium leaves the evaporator 22 via a second outlet 27 and passes a compressor 35 before it reaches the condenser 28 again via the second inlet 32.

Wenn die Flaschen die Flaschenreinigungsvorrichtung 1 passiert haben, können die gereinigten Flaschen aus den Flaschenzellen des Flaschenträgers entfernt und mit einem Abgabeband abtransportiert werden, beispielsweise hin zu einer Füllvorrichtung.When the bottles have passed the bottle cleaning device 1, the cleaned bottles can be removed from the bottle cells of the bottle carrier and transported away with a delivery belt, for example to a filling device.

Figur 2 zeigt ein Blockdiagramm einer zweiten Ausführungsform einer Flaschenreinigungsvorrichtung 38. Diese zweite Ausführungsform der Flaschenreinigungsvorrichtung 38 unterscheidet sich von der ersten Ausführungsform der Flaschenreinigungsvorrichtung 1 dadurch, dass für die erste 8 und die zweite Frischwasserspritzzone 9 nur ein Becken 39 vorgesehen ist statt zwei Becken. Figure 2 shows a block diagram of a second embodiment of a bottle washing device 38. This second embodiment of the bottle washing device 38 differs from the first embodiment of the bottle washing device 1 in that only one basin 39 is provided for the first 8 and the second fresh water spray zone 9 instead of two basins.

Die Flaschenreinigungsvorrichtung 38 weist einen Überlauf 40 zwischen dem einen Becken 39 und dem dritten Auffangbecken 13 auf. Des Weiteren weist diese Flaschenreinigungsvorrichtung 38 wie die erste Ausführungsform einen Überlauf 18 zwischen dem dritten 13 und dem zweiten Auffangbecken 12 und einen Überlauf 19 zwischen dem zweiten 12 und dem ersten Auffangbecken 11. Der Überlauf 20 des ersten Auffangbeckens 11 ist mit dem Vorweichbecken 2 verbunden. In den einzelnen Überläufen 40, 18, 19, 20 können Filter für eine Filterung des überlaufenden Wassers vorgesehen sein.The bottle washing device 38 has an overflow 40 between the one basin 39 and the third collecting basin 13. Furthermore, like the first embodiment, this bottle washing device 38 has an overflow 18 between the third 13 and second catch basin 12 and an overflow 19 between the second 12 and first catch basin 11. The overflow 20 of the first catch basin 11 is connected to the pre-soaking basin 2. Filters for filtering the overflowing water can be provided in the individual overflows 40, 18, 19, 20.

Aus dem einen Becken 39 wird aufgefangenes Wasser abgeleitet und einer Wasseraufbereitungsvorrichtung 16 zugeführt. Nach der Aufbereitung wird das Wasser als Spritzwasser in der ersten Frischwasserspritzzone 8 verwendet. In der Aufbereitung des Wassers können eine Abscheidung von Partikeln, eine Neutralisation, eine Abscheidung von Tensiden und/oder eine Hygienisierung erforderlich sein. Da das nichtaufbereitete Wasser der Frischwasserspritzzone entnommen wird, können möglicherweise die Partikelabscheidung und Hygienisierungsmaßnahmen entfallen, da in der zweiten Frischwasserspritzzone 9 die Flaschen mit Frischwasser klargespült werden.Collected water is diverted from one basin 39 and fed to a water treatment device 16. After the treatment, the water is used as spray water in the first fresh water spray zone 8. Separation of particles, neutralization, separation of surfactants and / or sanitation may be necessary in the treatment of the water. Since the unprocessed water is taken from the fresh water spray zone, particle separation and sanitation measures can possibly be dispensed with, since the bottles are rinsed clear with fresh water in the second fresh water spray zone 9.

Um dem Wärmeüberschuss, der durch die reduzierte Zufuhr von Frischwasser entsteht, Rechnung zu tragen, ist auch in der zweiten Ausführungsform der Flaschenreinigungsvorrichtung 38 eine aktive Kühlung vorgesehen, mittels der das Wasser in dem einen Becken 39, dem dritten 13, dem zweiten 12 und dem ersten Auffangbecken 11 gekühlt werden kann. Das eine Becken 39 und die drei Auffangbecken 11, 12, 13 sind jeweils mit Wärmetauschern ausgestattet und werden hintereinander geschaltet von einem Kühlmedium in einem Kühlkreislauf 21 durchströmt. Mittels dieses Kühlkreislaufs 21 kann dem Wasser in dem einen Becken 39 und in den drei Auffangbecken 11, 12, 13 die Wärmemenge entzogen werden, die zuvor durch den höheren Frischwasserdurchsatz des kaskadenförmigen Aufbaus einer Flaschenreinigungsmaschine des Stands der Technik abgeführt wurde.In order to take account of the excess heat that arises from the reduced supply of fresh water, active cooling is also provided in the second embodiment of the bottle washing device 38, by means of which the water in the one basin 39, the third 13, the second 12 and the first catch basin 11 can be cooled. The one basin 39 and the three collecting basins 11, 12, 13 are each equipped with heat exchangers and are connected in series by a cooling medium in a cooling circuit 21 flows through. By means of this cooling circuit 21, the amount of heat can be withdrawn from the water in the one basin 39 and in the three collecting basins 11, 12, 13 that was previously dissipated by the higher fresh water throughput of the cascade-like structure of a prior art bottle washing machine.

Das Kühlmedium in dem Kühlkreislauf 21 wird im Gleichstrom zur Fließrichtung des Wassers, das durch die Überläufe 40, 18, 19, 20 fließt, gefahren.The cooling medium in the cooling circuit 21 is driven in cocurrent to the direction of flow of the water flowing through the overflows 40, 18, 19, 20.

Das erwärmte Kühlmedium, das das erste Auffangbecken 11 verlässt, wird einem ersten Eingang 24 eines Verdampfers 22 einer Wärmepumpe 23 zugeführt. Das Kühlmedium kann eine Temperatur von etwa 60 °C aufweisen. In dem Verdampfer 22 wird das Kühlmedium zurückgekühlt und verlässt den Verdampfer 22 durch einen ersten Ausgang 25. Das Kühlmedium kann dann eine Temperatur in einem Bereich von 38 °C bis 42 °C aufweisen, insbesondere kann die Temperatur etwa 40 °C betragen. Von dort gelangt das Kühlmedium durch den Kühlkreislauf 21 zu dem einen Becken 39, wo dann eine Kühlung des Wassers in dem einen Becken 39, dem dritten 13, dem zweiten 12 und dem ersten Auffangbecken 11 erfolgt.The heated cooling medium that leaves the first collecting basin 11 is fed to a first inlet 24 of an evaporator 22 of a heat pump 23. The cooling medium can have a temperature of approximately 60 ° C. The cooling medium is cooled back in the evaporator 22 and leaves the evaporator 22 through a first outlet 25. The cooling medium can then have a temperature in a range from 38.degree. C. to 42.degree. C., in particular the temperature can be approximately 40.degree. From there, the cooling medium passes through the cooling circuit 21 to one basin 39, where the water is then cooled in one basin 39, the third 13, the second 12 and the first collecting basin 11.

Figur 3 zeigt eine dritte Ausführungsform einer Flaschenreinigungsvorrichtung 44, die der in der Figur 1 gezeigten ersten Ausführungsform der Flaschenreinigungsvorrichtung 1 entspricht, bis auf die erste Spritzzone 5 und dem zugehörigen Auffangbecken 11. In der dritten Ausführungsform umfasst die Flaschenreinigungsvorrichtung 44 eine dem Hauptlaugenbecken 3 in der Flaschentransportrichtung nachfolgende Nachlaugenspritzzone 46, in der Flüssigkeit aus einem Nachlaugenbecken 47 mittels einer Zuleitung mit einer Pumpe 36 den Spritzdüsen 10 der Nachlaugenspritzzone 47 zugeführt wird. Das Nachlaugenbecken 47 ist unterhalb der Nachlaugenspritzzone 46 angeordnet. Der Ausdruck "unterhalb angeordnet" bedeutet, dass sich das Nachlaugenbecken 47 in einer relativen Lage zu der Nachlaugenspritzzone 46 befindet, so dass es durch die Düsen 10 ausgegebenes Wasser auffangen kann. Die Nachlauge kann eine Temperatur in einem Bereich von 60 °C bis 65 °C aufweisen. Figure 3 FIG. 13 shows a third embodiment of a bottle washer 44 similar to that in FIG Figure 1 The first embodiment shown corresponds to the bottle cleaning device 1, with the exception of the first spray zone 5 and the associated collecting basin 11. In the third embodiment, the bottle cleaning device 44 comprises a post-caustic spray zone 46 following the main caustic basin 3 in the bottle transport direction, in which liquid from a post-caustic basin 47 by means of a feed line a pump 36 is fed to the spray nozzles 10 of the post-caustic spray zone 47. The post-caustic basin 47 is arranged below the post-caustic spray zone 46. The term “arranged below” means that the post-caustic basin 47 is in a position relative to the post-caustic spray zone 46 so that it can collect water dispensed through the nozzles 10. The post-caustic solution can have a temperature in a range from 60 ° C to 65 ° C.

Die Flüssigkeit aus dem Nachlaugenbecken 47 kann mittels der Spritzdüsen 10 auf und/oder in vorbeigeführte Flaschen gespritzt werden. In einer nicht dargestellten weiteren Ausführungsform der Flaschenreinigungsvorrichtung kann vorgesehen sein, dass die Flaschen in das Nachlaugenbecken 47 eingetaucht werden, ohne dass eine Spritzung erfolgt. In diesem Falle können die vorgesehenen Spritzdüsen 10 und die Zuleitung mit der Pumpe 36 entfallen; sie können aber auch vorgesehen sein, um beispielsweise abhängig vom gerade behandelten Flaschentyp eine auswählbare Alternative zur Verfügung stellen zu können.The liquid from the post-lye basin 47 can be sprayed onto and / or into bottles guided past by means of the spray nozzles 10. In a further embodiment of the bottle cleaning device, not shown, it can be provided that the bottles are immersed in the post-lye basin 47 without spraying. In this case, the spray nozzles 10 provided and the feed line with the pump 36 can be omitted; however, they can also be provided in order, for example, to be able to provide a selectable alternative depending on the type of bottle being treated.

Zwischen dem zweiten Auffangbecken 12 und dem Nachlaugenbecken 47 ist ein weiterer Überlauf 48 vorgesehen, der dazu ausgelegt ist, Wasser aus diesem Auffangbecken 12 demA further overflow 48 is provided between the second catch basin 12 and the post-lye basin 47, which is designed to collect water from this catch basin 12

Der zusätzliche Überlauf 49 zwischen dem Nachlaugenbecken 47 und dem Vorweichbecken 2 ist dazu ausgelegt, Nachlauge aus dem Nachlaugenbecken 47 dem Vorweichbecken 2 zuzuführen.To supply post-lye basin 47. The additional overflow 49 between the post-lye basin 47 and the pre-soaking basin 2 is designed to supply post-lye from the post-lye basin 47 to the pre-soaking basin 2.

Um dem Wärmeüberschuss, der durch die reduzierte Zufuhr von Frischwasser entsteht, Rechnung zu tragen, ist in der dritten Ausführungsform eine aktive Kühlung des Wassers in dem ersten Becken 14, dem dritten 13, dem zweiten 12 und dem Nachlaugenbecken 47 vorgesehen, die jeweils mit Wärmetauschern ausgestattet sind und hintereinander geschaltet von einem Kühlmedium in einem Kühlkreislauf 21 durchströmt werden. Mittels dieses Kühlkreislaufs 21 kann dem Wasser in dem ersten Becken 14, dem dritten 13, dem zweiten 12 und dem Nachlaugenbecken 47 die Wärmemenge entzogen werden, die zuvor durch den höheren Frischwasserdurchsatz des kaskadenförmigen Aufbaus einer Flaschenreinigungsmaschine des Stands der Technik abgeführt wurde.In order to take account of the excess heat that arises from the reduced supply of fresh water, active cooling of the water in the first basin 14, the third 13, the second 12 and the post-lye basin 47 is provided in the third embodiment, each with heat exchangers are equipped and connected one behind the other through which a cooling medium flows in a cooling circuit 21. By means of this cooling circuit 21, the amount of heat can be withdrawn from the water in the first basin 14, the third 13, the second 12 and the post-lye basin 47, which was previously dissipated by the higher fresh water throughput of the cascading structure of a prior art bottle washer.

Das Kühlmedium in dem Kühlkreislauf 21 wird im Gleichstrom zur Fließrichtung des Wassers, d.h. der Wassertransportrichtung, das durch die Überläufe 17, 18, 48, 49 fließt, gefahren.The cooling medium in the cooling circuit 21 is driven in cocurrent to the direction of flow of the water, i.e. the direction of water transport that flows through the overflows 17, 18, 48, 49.

Figur 4 zeigt eine vierte Ausführungsform einer Flaschenreinigungsvorrichtung 50, die im Wesentlichen der dritten Ausführungsform entspricht, wobei aber für die erste 8 und die zweite Frischwasserspritzzone 9 nur ein Becken 39 vorgesehen ist statt zwei Becken. Figure 4 shows a fourth embodiment of a bottle washing device 50, which essentially corresponds to the third embodiment, but with only one basin 39 instead of two basins being provided for the first 8 and the second fresh water spray zone 9.
