Description
Die Erfindung betrifft eine Reinigungsstation für die Reinigung von, insbesondere länglichen, Schalungselementen, wie sie beispielsweise in Betonfertigteil-Anlagen eingesetzt werden. Die Reinigungsstation weist eine Einhausung, durch die eine Fördereinrichtung zum Transport der Schalungselemente verläuft, und eine Reinigungseinrichtung auf.The invention relates to a cleaning station for the cleaning of, in particular elongated, formwork elements, as used for example in precast concrete plants. The cleaning station has an enclosure, through which a conveyor for transporting the formwork elements extends, and a cleaning device.
Zur Herstellung von Platten, Decken, Wänden oder dergleichen Betonteilen ist es bekannt, eine der äußeren Geometrie des herzustellenden Betonteils entsprechende, meist kastenartige, Form aus einer Auflage und darauf individuell platzierbaren Schalungselementen bereitzustellen, in welcher der Beton ggf. zusammen mit Bewehrungselementen oder dergleichen eingebracht wird. Aus der
Hierfür ist eine Reinigungsstation der oben genannten Art bekannt, bei der die Schalungselemente auf einer Förderstrecke eine Reinigungskabine durchlaufen, in der feststehende und/oder rotierende Bürsten anhaftende Betonreste von den Schalungselementen entfernen. Beispielsweise sind an fest definierten Positionen angeordnete rotatorisch angetriebene Rundbürsten vorgesehen, die von oben, unten und seitlich die Schalungselemente beim Durchlauf durch den Schalungsreiniger mechanisch reinigen. Die Schwierigkeit besteht bei diesem Reinigungskonzept darin, dass die Verunreinigungen der Schalungselemente durch Betonanhaftungen so stark sind, dass die Bürsten die Verunreinigungen nur unzureichend lösen können. Außerdem verschleißen die Bürsten während der Reinigung stark und müssen deshalb mechanisch oder pneumatisch nachgestellt werden.For this purpose, a cleaning station of the above-mentioned type is known, in which the shuttering elements pass through a cleaning cabin on a conveying path, in which fixed and / or rotating brushes remove adhering concrete residues from the shuttering elements. For example, rotatably driven rotary brushes arranged at fixedly defined positions are provided which mechanically clean the formwork elements from above, below and laterally as they pass through the formwork cleaner. The difficulty with this cleaning concept is that the contamination of the formwork elements by concrete adhesions are so strong that the brushes the impurities insufficient to be able to solve. In addition, the brush wear severely during cleaning and must therefore be adjusted mechanically or pneumatically.
Aufgabe der vorliegenden Erfindung ist es demgegenüber eine verbesserte Reinigungsstation der oben genannten Art bereitzustellen, welche die Nachteile der bekannten Lösungen vermeidet.In contrast, the object of the present invention is to provide an improved cleaning station of the abovementioned type, which avoids the disadvantages of the known solutions.
Diese Aufgabe wird erfindungsgemäß im Wesentlichen durch eine Reinigungsstation mit den Merkmalen des Anspruchs 1 gelöst. Der Erfindung liegt dabei der Gedanke zugrunde, ein Reinigungssystem einzusetzen, bei dem die Reinigung durch einen Hochdruck-Flüssigkeitsstrahl erfolgt. Durch den hohen Druck der Reinigungsflüssigkeit platzen Verunreinigungen von der Oberfläche der Schalungselemente ab. Zusätzlich zum Nassreinigungssystem befindet sich ein Trocknungssystem in dem Schalungsreinigungssystem. Nach einer bevorzugten Ausführungsform weist die Reinigungseinrichtung wenigstens eine Reinigungsdüse auf, die über eine Leitung mit einer Quelle eines Reinigungsmediums verbunden ist, und in der Einhausung ist wenigstens eine Trocknungsdüse vorgesehen, die über eine Leitung mit einer Gasquelle verbunden ist. Das Reinigungssystem kann dabei nach einer Ausführungsform vollständig auf den Einsatz von Bürsten verzichten. Alternativ ist es auch möglich, zusätzlich zu der Reinigung mittels eines oder mehrerer Hochdruck-Flüssigkeitsstrahlen auch statische und/oder angetriebene Bürsten zu verwenden.This object is achieved according to the invention essentially by a cleaning station having the features of
Die Reinigungseinrichtung ist vorzugsweise mit mehreren Reinigungsdüsen versehen, die zueinander in unterschiedlichen Richtungen ausgerichtet sind. So kann ein Reinigungsmedium beispielsweise von oben, von unten, und von beiden Seiten aus verschiedenen Düsen auf das zu reinigende Schalungselemente gerichtet werden. Der Aufbau der Reinigungsstation ist vergleichsweise einfach, wenn eine oder mehrere Reinigungsdüsen starr in der Einhausung befestigt sind.The cleaning device is preferably provided with a plurality of cleaning nozzles, which are aligned with each other in different directions. Thus, for example, a cleaning medium can be directed from above, from below, and from both sides from different nozzles onto the formwork elements to be cleaned. The construction of the cleaning station is comparatively easy if one or more cleaning nozzles are rigidly mounted in the housing.
Für ein optimales Reinigungsergebnis wird es jedoch bevorzugt, wenn zumindest einzelne Reinigungsdüsen in ihrer Ausrichtung einstellbar sind. Alternativ oder zusätzlich hierzu kann die Reinigungseinrichtung auch eine oder mehrere bewegbare Reinigungsdüsen aufweisen. Bewegbare Reinigungsdüsen können dabei durch den Druck des Reinigungsmediums in Bewegung versetzt werden, beispielsweise auf einer Kreisbahn, oder diese können durch einen externen Antrieb bewegt werden.For an optimal cleaning result, however, it is preferred if at least individual cleaning nozzles are adjustable in their orientation. Alternatively or additionally, the cleaning device may also have one or more movable cleaning nozzles. Movable cleaning nozzles can be set in motion by the pressure of the cleaning medium, for example on a circular path, or they can be moved by an external drive.
Es hat sich für die Reinigung von Schalungselementen einer Betonfertigteil-Anlage als besonders zweckmäßig erwiesen, wenn wenigstens eine Reinigungsdüse eine Fächerdüse ist. Mit einer solchen Fächerdüse lassen sich die Flächen von Schalungselementen rasch und gründlich reinigen. Alternativ oder zusätzlich ist wenigstens eine Reinigungsdüse eine Vollstrahldüse. Mit einer Vollstrahldüse lassen sich beispielsweise Bereiche eines Schalungselements, in denen Betonreste besonders stark anhaften, einer intensiveren Reinigung unterziehen.It has proved to be particularly useful for the cleaning of formwork elements of a precast concrete plant when at least one cleaning nozzle is a fan nozzle. With such a fan nozzle, the surfaces of formwork elements can be cleaned quickly and thoroughly. Alternatively or additionally, at least one cleaning nozzle is a full-jet nozzle. With a full-jet nozzle, for example, areas of a formwork element in which concrete residues adhere particularly strongly can be subjected to a more intensive cleaning.
Die Quelle des Reinigungsmediums weist beispielsweise eine Pumpe mit einer Förderleistung von wenigstens 20 l/min, insbesondere zwischen 25 l/min und 50 l/min, und einem Druck von wenigstens 10 bar, insbesondere zwischen 15 bar und 120 bar, aufweist. Vorzugsweise sind die Förderleistung und/oder der Druck regulierbar.The source of the cleaning medium has, for example, a pump with a delivery rate of at least 20 l / min, in particular between 25 l / min and 50 l / min, and a pressure of at least 10 bar, in particular between 15 bar and 120 bar. Preferably, the delivery rate and / or the pressure are adjustable.
Nach einer bevorzugten Ausführungsform wird das Reinigungsmedium in einem geschlossenen Kreislauf in der Reinigungsstation geführt. Hierzu kann die Quelle des Reinigungsmediums mit einem Reservoir verbunden sein, das mit einer Sammelleitung zum Ableiten von aus der wenigstens einen Reinigungsdüse austretendem Reinigungsmedium verbunden ist. Die Füllmenge des Flüssigkeitsreservoirs kann zweckmäßigerweise etwa 100 l bis etwa 150 l betragen.According to a preferred embodiment, the cleaning medium is guided in a closed circuit in the cleaning station. For this purpose, the source of the cleaning medium may be connected to a reservoir, which is connected to a manifold for discharging emerging from the at least one cleaning nozzle cleaning medium. The filling amount of the liquid reservoir may conveniently be about 100 l to about 150 l.
Um die Reinigungsdüsen vor Verstopfung zu schützen, kann dem Flüssigkeitsreservoir wenigstens eine Filtereinrichtung zugeordnet sein. Eine solche Filtereinrichtung kann der Sammelleitung nachgeschaltet vor dem Reservoir angeordnet sein und/oder zwischen dem Reservoir und der Pumpe oder auch der Pumpe nachgeschaltet vorgesehen sein. Zweckmäßigerweise ist die Filtereinrichtung mit mehrstufigen Filtern versehen, um zunächst gröbere Betonreste von dem Reinigungsmedium abzutrennen und anschließend das Reinigungsmedium weiter zu filtern. Für einen kontinuierlichen Betrieb der Reinigungsstation ist beispielsweise eine Filtration bis zu einer Partikelgröße von etwa 25 µm sinnvoll.In order to protect the cleaning nozzles from clogging, at least one filter device can be assigned to the liquid reservoir. Such a filter device may be arranged downstream of the reservoir before the reservoir and / or provided downstream between the reservoir and the pump or also the pump. The filter device is expediently provided with multi-stage filters in order first to separate coarser concrete residues from the cleaning medium and then to further filter the cleaning medium. For a continuous operation of the cleaning station, for example, a filtration up to a particle size of about 25 microns makes sense.
Das Reinigungsmedium kann eine Reinigungsflüssigkeit und/oder ein Schüttgut aufweisen. So kann das Reinigungsmedium beispielsweise eine Flüssigkeit, wie Wasser, sein oder eine Emulsion aus Wasser und Öl oder eine Suspension. Das Reinigungsmedium kann zusätzlich Feststoffe enthalten, die zumindest auf anhaftende Betonreste einen abrasiven Effekt haben.The cleaning medium may comprise a cleaning liquid and / or a bulk material. For example, the cleaning medium may be a liquid such as water or an emulsion of water and oil or a suspension. The cleaning medium may additionally contain solids which have an abrasive effect at least on adhering concrete residues.
Für einige Anwendungszwecke kann es vorteilhaft sein, wenn innerhalb oder außerhalb der Einhausung eine Einrichtung zum Klimatisieren des Reinigungsmediums und/oder des Trocknungsgases vorgesehen ist. Eine Klimatisierung dieser Medien kann eine Temperierung und, insbesondere hinsichtlich des Trocknungsgases, die Veränderung des Feuchtigkeitsgehalts bedeuten. So kann beispielsweise die Beaufschlagung der Schalungselemente mit erwärmtem Reinigungsmedium und/oder erwärmtem Trocknungsgas den Trocknungsvorgang verkürzen.For some applications, it may be advantageous if a device for conditioning the cleaning medium and / or the drying gas is provided inside or outside the housing. Air conditioning of these media can mean a temperature control and, in particular with regard to the drying gas, the change in the moisture content. For example, the loading of the formwork elements with heated cleaning medium and / or heated drying gas can shorten the drying process.
Die wenigstens eine Trocknungsdüse kann als eine Öffnung in der mit der Gasquelle verbundenen Leitung vorgesehen sein. Die Leitung kann beispielsweise im Bereich der Schalungselemente kleine Luftaustrittsöffnungen aufweisen, durch die die Luft ausströmt. Vorzugsweise weist die Gasquelle einen Luftverdichter, beispielsweise einen Seitenkanalverdichter, mit einer Luftförderleistung von wenigstens 5.000 l/min, insbesondere zwischen 7.500 l/min und 12.000 l/min, auf. Zum Beispiel besteht das Trocknungssystem aus einem Luftverdichter, der aus der Umgebung Luft ansaugt. Durch die Verdichtung hat die Luft typischerweise eine Temperatur größer als 60° C. Die Luft kann gefiltert und durch eine Leitung zu den Schalungselementen auf der Fördereinrichtung geführt werden.The at least one drying nozzle may be provided as an opening in the conduit connected to the gas source. For example, in the area of the formwork elements, the line can have small air outlet openings through which the air flows. The gas source preferably has an air compressor, for example a side channel compressor, with an air delivery capacity of at least 5,000 l / min, in particular between 7,500 l / min and 12,000 l / min, on. For example, the drying system consists of an air compressor that draws air from the environment. Due to the compression, the air typically has a temperature greater than 60 ° C. The air can be filtered and passed through a line to the formwork elements on the conveyor.
Nach einer bevorzugten Ausführungsform sind die wenigstens eine Trocknungsdüse und der Luftverdichter derart aufeinander abgestimmt, dass das aus der wenigstens einen Trocknungsdüse austretende Gas eine Geschwindigkeit von wenigstens 50 m/s, insbesondere zwischen 80 m/s und 200 m/s, zum Beispiel etwa 100 m/s, aufweist.According to a preferred embodiment, the at least one drying nozzle and the air compressor are coordinated such that the gas emerging from the at least one drying nozzle has a speed of at least 50 m / s, in particular between 80 m / s and 200 m / s, for example about 100 m / s.
Die Fördereinrichtung kann ein angetriebenes, insbesondere umlaufendes, Fördermittel aufweisen, das zumindest teilweise aus einem magnetisierbaren Material besteht. Beispielsweise ist das Fördermittel eine Kette und/oder ein Band. Das Fördermittel kann selbst aus einem magnetisierbaren Material bestehen oder Glieder aus einem magnetisierbaren Material aufweisen. Auf diese Weise ist es mit besonders einfachen Mitteln möglich, Schalungselemente durch Magnetkraft auf dem Fördermittel zu fixieren. Die Schalungselemente sind üblicherweise mit so starken Magneten versehen, dass diese während der Herstellung von Betonfertigteilen, d.h. beispielsweise auch während der Verdichtung durch Rüttler, nicht auf der Auflage verrutschen. Entsprechend ist es auch möglich, die Schalungselemente ausschließlich durch Magnetkraft an dem Fördermittel so zu befestigen, dass das Reinigungsmedium die Schalungselemente nicht von dem Fördermittel löst.The conveyor may have a driven, in particular rotating, conveying means, which consists at least partially of a magnetizable material. For example, the conveyor is a chain and / or a belt. The conveyor may itself consist of a magnetizable material or comprise members of a magnetizable material. In this way it is possible with particularly simple means to fix formwork elements by magnetic force on the conveyor. The shuttering elements are usually provided with magnets of such strength that they are used during the manufacture of prefabricated concrete parts, i. For example, even during compaction by vibrator, do not slip on the support. Accordingly, it is also possible to fix the formwork elements exclusively by magnetic force on the conveyor so that the cleaning medium does not release the formwork elements from the conveyor.
Es hat sich als zweckmäßig erwiesen, wenn die Fördereinrichtung eine durch die Einhausung verlaufende Rollenbahn aufweist. Eine solche Rollenbahn ermöglicht es, auch vergleichsweise lange Schalungselemente mit geringem Kraftaufwand zu bewegen, insbesondere der Reinigungsstation zuzuführen bzw. durch diese herauszuführen.It has proved to be expedient if the conveyor has a roller conveyor running through the housing. Such a roller conveyor makes it possible, even comparatively long formwork elements with little effort to move, in particular to supply the cleaning station or lead out through this.
Die Reinigungsstation kann eine eigene Steuerung aufweisen, über die der Antrieb der Fördereinrichtung, die Pumpe für das Reinigungsmedium und/oder der Verdichter für das Trocknungsgas gesteuert werden. Diese Steuerung kann auch Bestandteil der Steuerung einer Betonfertigteil-Anlage sein. Um bei in einer Betonfertigteil-Anlage im kontinuierlichen Betrieb anfallenden unterschiedlichen Größen von Schalungselementen eine effiziente und zügige Reinigung sicherzustellen, kann die Reinigungsstation innerhalb und/oder außerhalb der Einhausung der Fördereinrichtung zugeordnete Sensoren aufweisen, die mit der Steuerung der Fördereinrichtung verbunden sind. Derartige Sensoren können beispielsweise eine Reflexion-Lichtschranke oder ein induktiver Schalter sein. Derartige Sensoren können detektieren, ob in der Reinigungsstation ein Schalungselement vorhanden ist und wie groß dieses ist. Entsprechend lassen sich die Fördereinrichtung, die Pumpe für das Reinigungsmedium und/oder der Verdichter für das Trocknungsgas ansteuern.The cleaning station may have its own control over which the drive of the conveyor, the pump for the cleaning medium and / or the compressor for the drying gas are controlled. This control can also be part of the control of a precast concrete plant. In order to ensure efficient and rapid cleaning in the case of different sizes of formwork elements occurring in a precast concrete plant in continuous operation, the cleaning station may have sensors assigned within and / or outside the housing of the conveyor, which sensors are connected to the control of the conveyor. Such sensors may be, for example, a reflection light barrier or an inductive switch. Such sensors can detect whether a formwork element is present in the cleaning station and how large it is. Accordingly, the conveyor, the pump for the cleaning medium and / or the compressor for the drying gas can be controlled.
Vor der erneuten Verwendung der Schalungselemente in einer Betonfertigteil-Anlage kann es erforderlich sein, die Schalungselemente mit einem Trennmittel, beispielsweise Öl, zu benetzen. Hierzu kann die Reinigungsstation in Förderrichtung stromabwärts der wenigstens einen Trocknungsdüse eine Trennmittelsprüheinrichtung aufweisen.Before reuse of the formwork elements in a precast concrete plant, it may be necessary to wet the formwork elements with a release agent, such as oil. For this purpose, the cleaning station downstream of the at least one drying nozzle may have a release agent spraying device in the conveying direction.
Die Reinigungsstation kann auch ein Gerät zur Ultraschallreinigung in oder an der Kabine aufweisen. So ist beispielsweise innerhalb oder außerhalb der Einhausung eine Einrichtung zur Erzeugung und Übertragung von Ultraschall vorgesehen.The cleaning station can also have a device for ultrasonic cleaning in or on the cabin. Thus, for example, a device for generating and transmitting ultrasound is provided inside or outside the enclosure.
