Abstract
Description
Die Erfindung betrifft eine Absaugeinrichtung für intermittierend anfallende Abgase nach dem Oberbe griff des Patentanspruchs 1.The invention relates to a suction device for intermittent exhaust gases after the Oberbe handle of claim 1.
Derartige Absaugeinrichtungen werden in der Regel kontinuierlich betrieben. Hier eine möglichst wirtschaftliche auf das intermittiernde Anfallen der Gase abgestellte Absaugeinrichtung zu schaffen, ist die Aufgabe der vorliegenden Erfindung.Such suction devices are usually operated continuously. Here one if possible economic on the intermittent incidence to create a suction device for the gases, is the object of the present invention.
Gelöst wird sie durch eine Ausgestaltung der gattungs gemäßen Einrichtung nach den kennzeichnenden Merkmalen des Patentanspruchs.It is solved by a design of the genus modern facility according to the characteristic features of the claim.
Ein Ausführungsbeispiel ist in der Zeichnung darge stellt und wird nachfolgend näher beschrieben.An embodiment is shown in the drawing represents and is described in more detail below.
Das Beispiel betrifft die Absaugung bei einer Druck gießmaschine, bei der aus Trennmitteln und thermischen Vorgängen stammende Nebel und Dämpfe abzusaugen sind.The example concerns suction at a pressure casting machine, in which from release agents and thermal Mists and vapors originating from operations must be extracted.
Die Absaugdüsen 1, 2 und 4 zur Erfassung der aus dem Formbereich und aus dem Gießkammer- und Ofenbereich entweichenden Dämpfe und Nebel können über die gesamte Breite der Maschinenplatten der Druckgießmaschine reichen.The suction nozzles 1 , 2 and 4 for detecting the vapors and mists escaping from the molding area and from the casting chamber and furnace area can extend over the entire width of the machine plates of the die casting machine.
Durch kleinflächige, schlitzartige Düsenöffnungen werden hohe Absaugluftgeschwindigkeiten erreicht, wodurch beim Absaugvorgang auch weiter entfernt befindliche Dampf- und Nebelschwaden angesaugt werden.Through small-area, slot-like nozzle openings high exhaust air speeds are achieved, which means even more distant during the suction process Steam and fog are drawn in.
Die Klappen 3 sperren die schlitzartigen Düsenöffnungen ab, solange keine Dampf- und Nebelschwaden abzusaugen sind. Die Klappen 3 können elektromotorisch, pneumatisch, hydraulisch oder mechanisch (z.B. über die Bewegung der beweglichen Maschinenplatte) gesteuert werden.The flaps 3 shut off the slot-like nozzle openings as long as no steam and fog are to be extracted. The flaps 3 can be controlled by an electric motor, pneumatically, hydraulically or mechanically (for example via the movement of the movable machine plate).
Zweck der Klappen 3 ist es, die absaugseitig hinter den Absaugdüsenöffnungen zum Absauggebläse befindlichen Hohlräume abzusperren, so daß dort ein wesentlicher Unterdruck entsteht.The purpose of the flaps 3 is to shut off the cavities located on the suction side behind the suction nozzle openings to the suction fan, so that a substantial negative pressure is created there.
Bei Öffnung der Klappen 3 wirken die zwischen Klappe und Absauggebläse unter Unterdruck stehenden Volumina als Akkumulatoren für die abzusaugenden Nebel- und Dampfschwaden. Zusätzlich verringern sie den Leistungs bedarf der als Axial- oder Radiallüfter ausgebildeten Absauggebläse während der Zeit der Absperrwirkung der Klappen 3.When the flaps 3 are opened, the volumes under vacuum between the flap and the suction fan act as accumulators for the mist and steam to be extracted. In addition, they reduce the power requirement of the exhaust fans, which are designed as axial or radial fans, during the period when the flaps 3 are shut off.
Die erfindungsgemäße Ausgestaltung ist sinnvoll, da die Absaugwirkung nur während etwa 10% des gesamten Arbeitszyklus der Druckgießmaschine benötigt wird, nämlich in der Zeit, in der Dampf- und Nebelschwaden beim Öffnen der Form, beim Einbringen des Trennmittels in die Form und bei Dosieren des Gießmetalls in die Gießkammer entstehen. Auch nachgeschaltete Filter können wegen der nur zeitanteilig geringen Beauf schlagung mit Luft, Nebel und Dämpfen bei ent sprechend großer Auslegung der Räume zwischen Ansaug gebläse und Filter kleiner dimensioniert werden. The configuration according to the invention makes sense because the suction effect only during about 10% of the total Duty cycle of the die casting machine is required namely in the time in the steam and fog wafts when opening the mold, when inserting the release agent into the mold and when dosing the casting metal into the Casting chamber arise. Downstream filters too can because of the only temporarily small Beauf striking with air, fog and vapors at ent accordingly large dimensioning of the spaces between intake fans and filters can be dimensioned smaller.
Die Verbindung der Absaugdüsen mit dem Absauggebläse kann über ortsfeste Verrohrungen 5 erfolgen.The connection of the suction nozzles to the suction fan can take place via fixed piping 5 .
Die Verbindung der Absaugdüse 2 auf der beweglichen Maschinenplatte mit dem Ansauggebläse kann über zusammenschiebbare Hosenrohre oder bewegliche Metall oder Kunststoffschläuche erfolgen.The connection of the suction nozzle 2 on the movable machine plate with the suction fan can be made via collapsible downpipes or movable metal or plastic hoses.
Die Absaugdüsen 1, 2 und 4 können so dimensioniert werden, daß gegenüber anderen Absaugsystemen, vor allem Hauben, die Behinderung des Aufspannbereichs bei Rüstvorgängen gering ist. Außerdem sind Auto matisierungsgeräte im Formtrennbereich nicht in ihren Bewegungen beeinträchtigt.The suction nozzles 1 , 2 and 4 can be dimensioned in such a way that, compared to other suction systems, especially hoods, there is little hindrance to the clamping area during set-up processes. In addition, automation devices in the mold release area are not impaired in their movements.
Absauganlagen solcher Ausführungen können außer an Druckgießmaschinen an Kunststoffspritzmaschinen, Kokillengießmaschinen, Schmiedepressen, Kunst stofformpressen oder ähnlichen Vorrichtungen horizontaler oder vertikaler Bauart eingesetzt werden.Extraction systems of such designs can also be used Die casting machines on plastic injection machines, Chill casting machines, forging presses, art fabric molding presses or similar devices horizontal or vertical design can be used.
