Abstract
Description
Vorrichtung zum Absaugen von staubhaltigen und aerosolhaltigen, von einer mit Kühlschmierstoffen betreibbaren Werkzeugmaschine kommenden GasgemischenDevice for suction of dusty and aerosol-containing, operated by a coolant Machine tool coming gas mixtures
TECHNISCHES GEBIETTECHNICAL TERRITORY
Die Erfindung betrifft eine Vorrichtung, mit der die beim Betrieb einer mit Kühlschmierstoffen betriebenen Werkzeugmaschine entstehenden staubhaltigen und aerosolhaltigen Gasgemische abgesaugt werden können. Bei solchen Gasgemischen kann es unter ungünstigen Verhältnissen zu einem Brand, einer Verpuffung oder einer Explosion kommen.The invention relates to a device with which the operated with cooling lubricants Machine tool that contains dust and aerosol Gas mixtures can be extracted. With such gas mixtures, it can be under unfavorable conditions fire, explosion, or explosion.
STAND DER TECHNIKSTATE OF TECHNOLOGY
Bei der Zerspanung metallischer Werkstoffe und ähnlichen Bearbeitungsvorgängen können Werkzeugmaschinen eingesetzt werden, die mit Kühlschmierstoffen betrieben werden. Die dabei entstehenden Stäube, Nebel, Dämpfe, Gase, Rauche und gegebenenfalls Späne stellen eine äußerst problematische Verschmutzungs- und Schadstoffbelastung der die Werkzeugmaschine umgebenden Luft dar. Daher ist eine Absaugung und Filtrierung dieser die Werkzeugmaschine umgebenden Luft erforderlich.When machining metallic materials and the like machining operations can machine tools are used with cooling lubricants operate. The resulting dusts, mists, vapors, gases, Smoke and chips if necessary pose an extremely problematic Pollution and pollution of the machine tool surrounding air. Therefore, suction and filtration of this is the Machine tool surrounding air required.
Um den Verschmutzungsbereich möglichst gering zu halten, ist es bekannt, Werkzeugmaschinen mit einer Umhausung zu versehen. Von der Umhausung führt eine Abgasleitung zu einem Ölabscheider. In dem Ölabscheider werden Ölbestandteile und sonstige Partikel aus der Luft herausgefiltert und die Ölbestandteile wieder in den Kühlschmiermittelkreislauf der Werkzeugmaschine zurückgeführt . Aus dem Ölabscheider kann die von Öl und Stäuben und dergleichen Schadstoffen gereinigte Luft ins Freie abgeführt werden.To keep the pollution area as small as possible To keep it is known to machine tools with an enclosure to provide. Leading from the enclosure an exhaust pipe to an oil separator. In the oil separator become oil components and other particles filtered out of the air and the oil components back into the coolant circuit of the machine tool. Out the oil separator can that of oil and dusts and Such pollutants cleaned air are discharged outdoors.
Aus der
DARSTELLUNG DER ERFINDUNGPRESENTATION THE INVENTION
Ausgehend von diesem vorbekannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine verbesserte Druckentlastung im Zusammenhang mit dem Betrieb von Werkzeugmaschinen der eingangs genannten Art anzugeben.Based on this previously known State of the art, the invention has for its object a improved pressure relief in connection with the operation of To specify machine tools of the type mentioned.
Diese Erfindung ist durch die Merkmale des Anspruchs 1 gegeben. Sinnvolle Weiterbildungen der Erfindung sind Gegenstand von sich daran anschließenden weiteren Ansprüchen.This invention is through the features of claim 1 given. Useful developments of the invention are the subject of subsequent claims.
Die Erfindung beinhaltet, dass Druckentlastungseinrichtungen auch eingangsseitig und/oder ausgangsseitig des im Absaugsystem einer mit Kühlschmierstoffen betriebenen Werkzeugmaschine vorhandenen Ölabscheiders vorgesehen werden. Damit wird verhindert, dass die bei einem sehr plötzlichen Druckanstieg innerhalb der Umhausung der Werkzeugmaschine entstehenden Druckwellen sich durch die Absaugleitung hindurch in den Ölabscheider fortpflanzen und im Ölabscheider beträchtliche Schäden verursachen können. Diese Druckwellen werden durch die vor dem Ölabscheider vorhandene Druckentlastungseinrichtung aufgefangen und gefahrlos abgebaut. Für den Fall, dass beim Betrieb der Werkzeugmaschine in dem Ölabscheider eine Explosion oder eine Verpuffung auftritt, kann auch ausgangsseitig des Ölabscheiders eine entsprechende Druckentlastungseinrichtung vorgesehen werden. Die in diesem Falle im Ölabscheider entstehende Druckwelle kann damit nicht den ausgangsseitig des Ölabscheiders vorhandenen Saugventilator beschädigen. Außerdem kann diese Druckwelle sich auch nicht in Gegenrichtung in die Umhausung der Werkzeugmaschine hineinbewegen, da sie von der eingangsseitig des Ölabscheiders vorhandenen Druckentlastungseinrichtung aufgefangen und abgebaut werden kann.The invention includes pressure relief devices also on the input side and / or output side of the in the suction system one with cooling lubricants operated machine tool existing oil separator are provided. This prevents the in the event of a very sudden increase in pressure Pressure waves arising within the housing of the machine tool propagate through the suction line into the oil separator and in the oil separator considerable Cause damage can. These pressure waves are caused by the pressure relief device in front of the oil separator caught and dismantled safely. In the event that during operation the machine tool in the oil separator an explosion or deflagration can also occur on the outlet side of the oil separator a corresponding pressure relief device can be provided. The in this case in the oil separator The resulting pressure wave cannot reach the output side of the oil separator Damage the existing suction fan. Besides, can this pressure wave also does not move in the opposite direction into the housing the machine tool as it moves from the input side of the oil separator existing pressure relief device collected and dismantled can be.
Als Druckentlastungseinrichtung kann ein an sich bekannter Bersttopf mit einer schwenkbaren Druckentlastungsklappe vorgesehen werden. Als Druckentlastungseinrichtungen können auch eine Berstscheibe oder Druckentlastungsventile wie beispielsweise Tellerventile vorgesehen werden.Can be used as a pressure relief device a bursting pot known per se with a swiveling pressure relief flap be provided. Can also be used as pressure relief devices a rupture disc or pressure relief valves such as Poppet valves are provided.
Weitere Ausgestaltungen und Vorteile der Erfindung auch im Zusammenhang mit der Ausbildung einer einen Bersttopf aufweisenden Druckentlastungseinrichtung sind den in den Ansprüchen ferner aufgeführten Merkmalen sowie dem in der Zeichnung dargestellten Ausführungsbeispiel zu entnehmen.Further configurations and advantages the invention also in connection with the formation of a Bursting pressure relief device are those in the claims also listed Features and the embodiment shown in the drawing refer to.
