Description
Die Erfindung bezeichnet eine Kühl- und Spülvorrichtung für Werkzeuge zur Bearbeitung von Gestein, vorzugsweise für in Diamantkernbohrgeräte eingesetzte Kernbohrkronen für Mauerwerk, Beton oder Gestein.The invention relates to a cooling and rinsing device for tools for machining Rock, preferably for core drill bits used in diamond core drilling machines Masonry, concrete or stone.
Bei Kühl- und Spülvorrichtungen für Werkzeuge oder Werkzeuggeräte im allgemeinen wird ein fluides Kühl- und Spülmittel wie Wasser in einem geschlossenen Spülkreislauf mit einem Sammelbehälter mittels einer Pumpe zumindest über Teile des Werkzeugs gefördert.In cooling and flushing devices for tools or tool devices in general a fluid coolant and flushing agent such as water in a closed flushing circuit with one Collection container conveyed by means of a pump at least over parts of the tool.
Nach der EP36814 beinhaltet die Kühl- und Spülvorrichtung für ein Werkzeug in Form einer Steinsäge mit einem über Kühl- und Spülmittel gekühlten Steinsägeblatt einen Sammelbehälter und einen, über ein Schwimmerventil angeschlossenen, Vorratsbehälter, welcher den Sammelbehälter automatisch nachfüllt. Diese Kühl- und Spülvorrichtung ohne Pumpe bildet keinen geschlossenen Spülkreislauf aus und benötigt daher zumindest diskontinuierlich eine Auffüllung von Kühl- und Spülmittel.According to EP36814, the cooling and rinsing device for a tool in the form of a Stone saw with a stone saw blade cooled with coolant and washing-up liquid and a storage tank connected via a float valve, which holds the Refills the collection container automatically. This cooling and rinsing device forms without a pump does not have a closed rinsing cycle and therefore needs one at least discontinuously Refill of coolant and detergent.
Nach der US3782501 beinhaltet die Kühl- und Spülvorrichtung für ein Werkzeuggerät innerhalb eines Sammelbehälters ein Schwimmerventil, welches in einem geschlossenen Kreislauf mit Vorratsbehälter, Pumpe und Filter für eine Kontrollschaltung den Kühl- bzw. Schmiermitteldurchfluss bestimmt und abhängig davon das Werkzeuggerät blockiert.According to US3782501, the cooling and rinsing device for a tool device a float valve inside a collecting tank, which is in a closed Circuit with reservoir, pump and filter for a control circuit for the cooling or Lubricant flow determined and depending on it blocked the tool.
Nach der EP0941828 weist eine Kühl- und Spülvorrichtung für in Diamantkernbohrgeräte eingesetzte Kernbohrkronen einen Sammelbehälter mit einer Saugpumpe und einen über eine Druckpumpe angeschlossenen Filter in einem geschlossenen Spülkreislauf auf. Der Sammelbehälter, welcher die gesamte Menge an Kühl- und Spülmittel aufnehmen muss, kann bei grösseren benötigten Mengen an Kühl- und Spülmittel aufgrund seines Volumens und seiner Masse nicht in allen Anwendungsfällen nahe dem Werkzeug angeordnet werden.According to EP0941828 has a cooling and rinsing device for in diamond core drilling machines used core drill bits a collecting container with a suction pump and one over a pressure pump connected filter in a closed flushing circuit. The Collection container, which has to hold the entire amount of coolant and detergent, can with larger amounts of coolant and detergent due to its volume and its mass can not be arranged near the tool in all applications.
Die Aufgabe der Erfindung besteht in der Realisierung einer Kühl- und Spülvorrichtung für Werkzeuge zur Bearbeitung von Gestein, deren Sammelbehälter auch bei grösseren benötigten Mengen an Kühl- und Spülmittel nahe am Werkzeug angeordnet werden kann. The object of the invention is to implement a cooling and rinsing device for Tools for processing stone, their collection containers even with larger ones required amounts of coolant and detergent can be arranged close to the tool.
Die Aufgabe wird im wesentlichen durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The task is essentially solved by the features of the independent claims. Advantageous further developments result from the subclaims.
Die Kühl- und Spülvorrichtung weist ein Kühl- und Spülmittel in einem geschlossenen Sammelbehälter auf, welcher über eine Saugpumpe zur Erzeugung eines Unterdrucks mit der Atmosphäre verbundenen ist und einem geschlossenen Spülkreislauf vom Sammelbehälter durch einen über eine Druckpumpe zur Erzeugung des Spülkreislaufs angeschlossenen Filter zur Reinigung des Kühl- und Spülmittels und durch ein dem Werkzeug zugeordnetes Auffangmittel zum Sammeln des vom Werkzeug zurückfliessenden verunreinigten Kühl- und Spülmittels mit einer Saugleitung zurück zum Sammelbehälter. Im wesentlichen ist dieser Spülkreislauf mit einem Vorratskreislauf kombiniert, bei welchem Kühl- und Spülmittel, vermittelt durch die mit dem Sammelbehälter verbundene Saugpumpe und den im Spülkreislauf über dem Auffangmittel und der Saugleitung auf Grund des Strömungswiderstands gegenüber der Atmosphäre ausgebildeten Unterdruck zum Aufsaugen des Kühl- und Spülmittels, von einem offenen Vorratsbehälter in den Sammelbehälter gesaugt wird, wenn ein im Sammelbehälter angeordnetes Schwimmerventil zur Regelung des Füllstandes geöffnet ist. Das Kühl- und Spülmittel des Vorratskreislaufs gelangt gemeinsam mit dem Kühl- und Spülmittel des Spülkreislaufes durch die Druckpumpe in den Filter und fliesst über einen Filterkonzentratabfluss am unteren Ende des Filters als verschmutztes Kühl- und Spülmittel zurück in den Vorratsbehälter.The cooling and flushing device has a coolant and flushing agent in a closed one Collection container, which with a suction pump to generate a vacuum is connected to the atmosphere and a closed flushing circuit from the collection container by one connected via a pressure pump to generate the flushing circuit Filters for cleaning the coolant and dishwashing liquid and through one assigned to the tool Collecting agent for collecting the contaminated material flowing back from the tool Coolant and flushing agent with a suction line back to the collection container. In essence it is this rinsing circuit combines with a supply circuit in which coolant and detergent, mediated by the suction pump connected to the collection container and in the rinsing circuit above the catchment and the suction line due to the flow resistance vacuum developed to absorb the cooling and Detergent is sucked into the collection container from an open storage container when a float valve arranged in the collecting tank for regulating the fill level is open. The coolant and flushing agent in the supply circuit arrive together with the Coolant and flushing agent of the flushing circuit through the pressure pump into the filter and overflows a filter concentrate drain at the bottom of the filter as a dirty cooling and Detergent back into the storage container.
Bei völlig geöffnetem Schwimmerventil überwiegt der Zufluss aus dem Vorratsbehälter den Abfluss in den Vorratsbehälter und gleicht somit fehlendes Kühl- und Spülmittel im Spülkreislauf aus. Bei geschlossenem Schwimmerventil überwiegt der Abfluss in den Vorratsbehälter den Zufluss aus dem Vorratsbehälter und entfernt somit überschüssiges Kühl- und Spülmittel aus dem Spülkreislauf. Durch den kombinierten Vorratskreislauf kann der Sammelbehälter sehr klein ausgeführt und somit nahe am Werkzeug angeordnet werden, wodurch das Aufsaugen des Kühl- und Spülmittels über das Auffangmittel verbessert wird, bzw. können bei gleichem Sammelbehälter grössere Mengen an Kühl- und Spülmittel verwendet werden.When the float valve is fully open, the inflow from the reservoir predominates Drain into the reservoir and thus compensates for the lack of coolant and detergent in the Rinsing cycle off. When the float valve is closed, the outflow predominates in the Storage container the inflow from the storage container and thus removes excess Coolant and flushing agent from the flushing circuit. Thanks to the combined supply cycle the collection container is made very small and thus arranged close to the tool be, so that the suction of the coolant and flushing agent through the collecting agent is improved, or larger quantities of cooling and Detergent can be used.
Vorteilhaft ist ein zu kühlendes Werkzeuggerät zwischen Filter und Werkzeug in den Spülkreislauf integriert.A tool device to be cooled between filter and tool in the is advantageous Integrated rinsing circuit.
Vorteilhaft sind die Saugpumpe und die Druckpumpe durch einen gemeinsamen Antrieb kombiniert, welcher weiter vorteilhaft mit dem Antrieb des Werkzeuggerätes kombiniert ist. The suction pump and the pressure pump are advantageous due to a common drive combined, which is further advantageously combined with the drive of the tool device.
Vorteilhaft beinhaltet das Werkzeuggerät den Sammelbehälter und weiter vorteilhaft den Vorratsbehälter, wobei weiter vorteilhaft das Werkzeuggerät als Kernbohrgerät ausgeführt ist.The tool device advantageously contains the collecting container and further advantageously the Storage container, with the tool device also advantageously being designed as a core drilling device is.
Vorteilhaft ist der Sammelbehälter schwimmbar auf dem Kühl- und Spülmittel des Vorratsbehälters ausgeführt, wodurch nur ein sehr geringer Unterdruck zur Förderung des Vorratskreislaufs notwendig ist.The collecting container is advantageously floatable on the coolant and flushing agent of the storage container executed, whereby only a very low negative pressure to promote the supply cycle necessary is.
Vorteilhaft ist das Auffangmittel als ein, eine Kernbohrkrone koaxial im Inneren radial dichtend aufnehmender, einseitig axial offener und am Rand axial gegen eine Fläche dichtender Torus mit einem Anschluss für eine Saugleitung ausgeführt.The collecting means is advantageous as a, a core drill bit coaxially inside radially sealing, axially open on one side and axially against a surface at the edge sealing torus with a connection for a suction line.
