Description

Die Erfindung betrifft eine .Maschine zur Herstellung eines einwandfreien vollständig luft- und strukturfreien Massehubels, insbesondere Solche für Porzellan und elektrotechnische Spezialmassen. Die Herstellung eines derartigen Massevollhubels ist mit den bereits vorhandenen Vakuumstrangpressen, Schlagmaschinen und Kammerfilterprzssen nicht möglich. Die derzeit gezogenen Massevollhubel weisen durch den Schneckenvorschub der Strangpresse Strukturbildung im Strang und auch im gebrannten Stück auf.The invention relates to a .Maschine for producing a perfect Completely air- and structure-free mass lifting device, especially those for porcelain and electrotechnical special masses. The manufacture of such a fully-fledged mass hoist is with the existing vacuum extrusion presses, impact machines and chamber filter presses not possible. The currently drawn full mass lifters point through the screw feed the extrusion press structure formation in the strand and also in the fired piece.

Diese Fehler und Erscheinungen werden bei der vorgeschlagenen Maschine beseitigt. Die derzeitige Arbeitsweise wird durch die Maschine besonders vereinfacht und erfolgt in zwei Arbeitsgängen, und zwar erstens in Abfiltern und zweitens mit Ausstoßen des Hubels.These errors and phenomena will occur in the proposed machine eliminated. The current way of working is particularly simplified by the machine and takes place in two steps, firstly in filtering and secondly with Ejection of the hub.

Die Erfindung ist in der Zeichnung beispielsweise dargestellt.The invention is shown in the drawing, for example.

Beim ersten Arbeitsgang wird erfindungsgemäß die Gegendruckplatte b an den Filterzylinder a angeschraubt.According to the invention, the counter-pressure plate is used in the first working step b screwed to the filter cylinder a.

Der Filterzylinder a ist durch einen abgedichteten Boden c durch die angebrachte Vakuumpumpe V entlüftet. Auf dem Massezuflußrohr d befindet sich ein gerillter Kolbenkopf e (mit Wasserabflußbohrungen versehen), in welchem der Siebblechtopf f sitzt und auf diesem das Filtertuch g befestigt ist, welches von dem Masseabatreifer h, der von dem Getriebemotor G stetig gedreht wird, von anhaftender Masse frei gehalten wird. Mittels einer Kolbenpumpe K wird durch den Zulaufschlauch -rre in den vorderen Teil des Filterzylinders a flüssiger Masseschlicker gepumpt. Durch den so entstandenen Druck und auf der Gegenseite durch das Vakuum, welches mit der Vakuumpumpe h erzeugt wird, kommt ein beschleunigtes Abfiltern zustande. Den Gegendruck regelt ein hydraulischer Kolben i, der mit dem Massezuflußrohr d verbunden ist. Nach Beendigung der Abfilterung wird der gesamte Filterkolben zurückgezogen und durch eine Druckplatte ersetzt. Danach wird die Gegendruckplatte b entfernt und das gewünschte Mundstück n aufgesetzt. Daraufhin wird mit dem hydraulischen Kolben i der Hubel gezogen.The filter cylinder a is vented through a sealed base c by the attached vacuum pump V. On the mass inflow pipe d is a grooved piston head e (provided with water drainage holes), in which the sheet metal pot f sits and on this the filter cloth g is attached, which is free of adhering mass by the mass removal gripper h, which is continuously rotated by the gear motor G is held. By means of a piston pump K, liquid mass slip is pumped through the inlet hose -rre into the front part of the filter cylinder a. The resulting pressure and, on the other hand, the vacuum that is generated with the vacuum pump h, accelerates the filtering process. The counter pressure is regulated by a hydraulic piston i, which is connected to the mass inflow pipe d. When the filtering process is complete, the entire filter flask is withdrawn and replaced by a pressure plate. Then the counter-pressure plate b is removed and the desired mouthpiece n is put on. The hydraulic piston i then pulls the hub.

Nach Beendigung dieses Arbeitsvorganges wird der Mundsfückverschlußkopf I, welcher ein Herausdeücken der Masse während des Filterns verhindert, aufgesetzt.After completion of this process, the mouthpiece closure head I, which prevents the mass from being pushed out during the filtering, is put on.
