Description

Vorrichtung zur Abreinigung von durch umweltschädliche Medien kontaminierte Verkehrsflächen Device for cleaning traffic areas contaminated by environmentally harmful media
Die Erfindung betrifft eine Vorrichtung zur Abreinigung von durch umweltschädliche Medien, wie Schmiermittel, Kraftstoffe oder dergleichen kontaminierte Verkehrsflächen, bei der eine mit hohem Volumenstrom absaugbare Haube dicht über der zu reinigenden Verkehrsfläche verfahrbar ist und in der Haube eine oder mehrere um eine vertikale Achse rotierende, zur Verkehrsfläche gerichtete Sprühdüsen angeordnet sind.The invention relates to a device for cleaning traffic areas contaminated by environmentally harmful media, such as lubricants, fuels or the like, in which a hood that can be extracted with a high volume flow can be moved close above the traffic area to be cleaned and in the hood one or more rotating around a vertical axis, spray nozzles facing the traffic area are arranged.
Eine solche Vorrichtung ist aus der EP 0 318 074 A1 bekannt. Sie ist als verfahrbare Einheit konzipiert und wird als Anhänger zu einer Fahreinheit eingesetzt. Bei solchen Vorrichtungen wird eine mit Lösungs- und/oder Emulgiermittel in Wasser versetzte Reinigungsflüssigkeit verwendet, welche die Fähigkeit besitzt, die genannten umweltschädlichen Medien in Lösung oder in Emulsion zu bringen. Die Reinigungslösung wird unter Hochdruck in die dicht über den zu reinigenden Boden geführte Haube gebracht und durch zur Verkehrsfläche hin gerichtete rotierenden Sprühdüsen versprüht. Dabei soll der entstehende rückprallende mit den aufgenommenen Verunreinigungen benetzte Sprühnebel durch eine tangentiale Öffnung in der im wesentlichen runden Haube abgesaugt werden. Es zeigt sich in der Praxis, daß solche Vorrichtungen jedoch nur unzureichend Reinigungsergebnisse erzielen und einen hohen Flüssigkeitseinsatz erfordern. Insbesondere bei der Reinigung von sehr ebenen Flächen sind die Reinigungsergebnisse unbefriedigend, da es zu Abrissen des erforderlichen hohen Volumenstromes kommt. Diese Vorrichtungen saugen sich dabei sozusagen an der Fläche fest. Es können daher nicht ausreichend große Luftmengen angesaugt werden, die erst den erforderlichen hohen Volumenstrom und damit die hohen Strömungsgeschwindigkeiten möglich machen.Such a device is known from EP 0 318 074 A1. It is designed as a mobile unit and is used as a trailer for a driving unit. In the case of such devices, a cleaning liquid which has been mixed with water and a solvent and / or emulsifier is used and has the ability to dissolve or emulsify the environmentally harmful media mentioned. The cleaning solution is brought under high pressure into the hood, which is guided close to the floor to be cleaned, and sprayed by rotating spray nozzles facing the traffic area. The resulting rebounding spray mist wetted with the contaminants taken up is to be suctioned off through a tangential opening in the essentially round hood. It has been shown in practice that such devices, however, achieve insufficient cleaning results and require a high level of fluid consumption. The cleaning results are unsatisfactory, especially when cleaning very flat surfaces, since the required high volume flow is interrupted. These devices suck themselves on the surface, so to speak. Sufficiently large amounts of air cannot therefore be drawn in, which only make the required high volume flow and thus the high flow velocities possible.
Aus der EP 0 162 769 A1 ist eine stationär zu benutzende Vorrichtung mit einer absaugbaren Haube bekannt, in dessen Haubenwand eine Entlüftungsbohrung vorgesehen ist, um ein zu hohes Vakuum in der Haube zu vermeiden. Diese Vorrichtung arbeitet nicht mit Reinigungsflüssigkeiten und Spritzdüsen, sie ist daher nur dazu geeignet, oberflächige Abfallstoffe aufzunehmen.EP 0 162 769 A1 discloses a device to be used in a stationary manner with an extractable hood, in the hood wall of which a vent hole is provided in order to avoid excessive vacuum in the hood. This device does not work with cleaning fluids and spray nozzles, it is therefore only suitable for picking up surface waste.
Die Aufgabe der Erfindung besteht darin, eine Vorrichtung der eingangs genannten Art vorzuschlagen, deren Wirkungsgrad und erhöht deren Verbrauch an Reinigungsflüssigkeit erniedrigt ist gegenüber den aus dem Stand der Technik bekannten Vorrichtungen.The object of the invention is to propose a device of the type mentioned, the efficiency and increased consumption of cleaning fluid is reduced compared to the devices known from the prior art.
Gelöst wird die Erfindungsaufgabe mit einer Vorrichtung mit den Merk- malen des Anspruches 1. Durch die erfindungsgemäße Anordnung von Belüftungseiementen in der Haubenwand oder dem Haubendach, die sich bei zu hohen Unterdrücken selbsttätig zunehmend öffnen mit zunehmendem Unterdruck wird erreicht, daß bei zu dichter Anlage der Haube am zu reinigenden Untergrund zusätzlich Luft durch diese Belüftungselementen angesaugt wird, um den erforderlichen hohen Volumenstrom aufrecht zu erhalten. Damit wird sichergestellt, daß der mit Verunreinigungen benetzte Sprühnebel sofort und sicher aus der Haube abgeführt werden kann. Bei zu niedrigen Volumenströmen besteht die Gefahr, daß Tröpfchen dieses Sprühnebels wieder auf die zu reinigenden Flächen zurückfallen und da- mit den Reinigungseffekt negativ beeinflussen. Die Belüftungselemente, vorzugsweise Belüftungskiappen, können sowohl in den Seitenwänden und deren Verlängerung nach unten in Form einer Dichtungsschürze als auch im Dachbereich der Haube vorsehen werdenThe object of the invention is achieved with a device having the features of claim 1. The arrangement according to the invention of ventilation elements in the hood wall or the hood roof, which automatically open when the pressures are too high, increases with increasing vacuum, so that if the system is too tight, the Hood on the surface to be cleaned is additionally sucked in air through these ventilation elements in order to maintain the required high volume flow. This ensures that the spray mist wetted with contaminants can be removed immediately and safely from the hood. If the volume flows are too low, there is a risk that droplets of this spray will fall back onto the surfaces to be cleaned and thus have a negative effect on the cleaning effect. The ventilation elements, preferably ventilation valves, can be provided both in the side walls and their downward extension in the form of a sealing apron and in the roof area of the hood
Nach einer bevorzugten Ausführungsart der Erfindung öffnen sich die Belüftungskiappen ab einem Unterdruck der Haube, der größer als 100 mbar ist. Entsprechend der gewählten Federkennlinie der Öffnungsfeder der Belüftungskiappen öffnen sich diese Klappen zunehmend mit zunehmendem Unterdruck.According to a preferred embodiment of the invention, the ventilation valves open from a vacuum of the hood that is greater than 100 mbar. According to the selected spring characteristic of the opening spring of the ventilation valve, these valves open with increasing vacuum.
Nach einer weiteren bevorzugten Ausgestaltung der Erfindung wird vorgeschlagen, die Absaugung der Haube im Bereich ihrer hinteren unteren Kante in Fahrtrichtung gesehen vorzusehen. Zweckmäßigerweise liegt die Absaugung dabei gegenüber der oder den Belüftungskiappen.According to a further preferred embodiment of the invention, it is proposed to provide the suction of the hood in the area of its rear lower edge in the direction of travel. The suction is expediently located opposite the ventilation valve (s).
Die Belüftungskiappen können auch an der schürzenartigen Dichtung vorgesehen sein. Anhand eines abgebildeten Ausführungsbeispieles wird die Erfindung im folgenden näher erläutert. Es zeigen:The ventilation valve can also be provided on the skirt-like seal. The invention is explained in more detail below on the basis of an illustrated exemplary embodiment. Show it:

Die vorzugsweise in Fahrtrichtung A zu bewegende Haube 1 wird dicht über eine zu reinigende Fläche 6 bzw. 6' geführt. Zur ausreichenden Abdichtung weist diese Haube 1 an der Unterseite ihrer Seitenwände 12 umlaufend eine elastische Dichtung 3 auf. Durch die Sprühdüsen 7, deren Rotationsarme mit der Ziffer 71 bezeichnet sind, wird unter hohem Druck Reinigungsflüssigkeit gegen die zu reinigenden Flächen 6 bzw. 6' ge- sprüht. Eine Absaugung des rückprallenden Sprühnebels erfolgt über die kanalartige Öffnung 14 an der hinteren Kante der Haube 1. Der Absaugkanal ist mit der Ziffer 2 bezeichnet. Die Absaugung erfolgt mit hohem Volumenstrom. Aufgrund des Unterdruckes in der Haube wird Luft zwischen den Flächen 6 bzw. 6' und den Dichtungen 3 angesaugt. Um einen nicht zu hohen Unterdruck in der Haube 1 entstehen zu lassen, der zu einer Festsaugung der Haube 1 am Untergrund führen könnte, sind in der Haubenwand 12 federnd beaufschlagte Belüftungskiappen 4 vorgesehen, die sich ab vorherbestimmten Unterdruckverhältnissen in der Haube entgegen dem Druck der Schließfeder 5 öffnen. Bevorzugt sollen sich diese Belüftungskiappen 4 ab einem Unterdruck in der Haube 1 größer 100 mbar mit zunehmendem Druck zunehmend öffnen. Aufgrund der Abstimmung mit den Federkennlinien wird dadurch ein allmähliches Öffnen der Belüftungskiappen 4 erreicht, so daß eine Vergleichsmäßigung des Volumenstromes durch die Haube hindurch zur Absaugung gewährleistet wird.The hood 1, which is preferably to be moved in the direction of travel A, is guided tightly over a surface 6 or 6 'to be cleaned. For sufficient sealing, this hood 1 has an elastic seal 3 all around on the underside of its side walls 12. The spray nozzles 7, the rotation arms of which are designated by the number 71, are used to spray cleaning liquid against the surfaces 6 or 6 ′ to be cleaned under high pressure. The rebounding spray is extracted via the channel-like opening 14 at the rear edge of the hood 1. The suction channel is designated by the number 2. The extraction takes place with a high volume flow. Due to the negative pressure in the hood, air is sucked in between the surfaces 6 and 6 'and the seals 3. In order not to create a too high negative pressure in the hood 1, which could lead to the hood 1 being sucked tightly onto the subsurface, resiliently actuated ventilation plugs 4 are provided in the hood wall 12, which counteract the pressure of the closing spring from predetermined vacuum conditions in the hood 5 open. From a vacuum in the hood 1 greater than 100 mbar, these ventilation valves 4 should preferably open increasingly with increasing pressure. Due to the coordination with the spring characteristics, a gradual opening of the ventilation valve 4 is achieved, so that an equalization of the volume flow through the hood is ensured for suction.
Je nach Haubengröße, Fahrgeschwindigkeit und möglichen Absaugkapazitäten sind diese Öffnungsunterdrücke festzulegen. Die Rotationsbereiche der Sprühdüsen 7 sind durch Schürzen 8 seitlich abgeschirmt, um zu erreichen, daß die Sprühnebel entsprechend gerichtete auf kürzestem Wege zum Absaugkanal 2 bzw. der Eintrittsöffnung 14 geführt werden. Die Versorgung der Sprühdüsen 7 erfolgt über die rotierende Wasserzuführung 72 in dem Haubendach 11. Zugehörige Antriebseinheiten sind nicht dargestellt. Depending on the hood size, driving speed and possible suction capacities, these opening pressures must be specified. The areas of rotation of the spray nozzles 7 are shielded laterally by aprons 8 in order to ensure that the spray mist is directed in the shortest possible way to the suction channel 2 or the inlet opening 14. The spray nozzles 7 are supplied via the rotating water supply 72 in the hood roof 11. Associated drive units are not shown.
