Description

Die Erfindung betrifft eine Vakuumpresse zur kontinuierlichen Erzeugung von plastischen Massesträngen. Anwendungsgebiet der Erfindung ist insbesondere die Keramikindustrie.The invention relates to a vacuum press for the continuous production of plastic mass strands. The field of application of the invention is in particular the ceramic industry.

Die bekannten Vakuumpressen bestehen im allgemeinen aus einer Oberpresse oder auch Mischer sowie einer Unterpresse, wobei zwecks Vakuumierung der Masse eine Vakuumkammer zwischengeschaltet ist.The known vacuum presses generally consist of an upper press or also a mixer and a lower press, a vacuum chamber being interposed for the purpose of vacuuming the mass.

Zur Einhaltung einer hohen Massestrangqualität ist es erforderlich die Vakuumpresse relativ häufig zu reinigen, um z.B. verhärtete Masseeinschlüsse im Massestrang auszuschließen.To maintain a high mass strand quality, it is necessary to clean the vacuum press relatively often, e.g. to exclude hardened mass inclusions in the mass strand.

Nachteiligerweise ist die Reinigung der bekannten Vakuumpressen häufig aufwendig, da die mit Masse in Berührung kommenden Maschinenteile nur schwer oder erst nach einer gewissen Teildemontage der Vakuumpresse zugänglich sind. Bei einer bekannten Vakuumpresse ist für Reinigungsarbeiten die Vakuumkammer diagonal geteilt und der Preßzylinder der Unterpresse klappbar ausgebildet. Reinigungsmöglichkeiten der Oberpresse sind jedoch kaum gegeben.Disadvantageously, cleaning the known vacuum presses is often complex, since the machine parts that come into contact with the mass are difficult to access or can only be accessed after a certain partial dismantling of the vacuum press. In a known vacuum press, the vacuum chamber is divided diagonally for cleaning work and the press cylinder of the lower press is designed to be foldable. There are hardly any cleaning options for the upper press.

Bei einer anderen bekannt gewordenen Vakuumpresse sind in Höhe der Einräumerwalzen, die den Masseeinzug in die Preßschnecke unterstützen, seitliche Deckel vorgesehen. Eine wesentliche Verbesserung der Reinigungsmöglichkeiten wird durch diese Lösung allerdings nicht erreicht.In another vacuum press that has become known, lateral covers are provided at the level of the broaching rollers, which support the mass feed into the press screw. However, this solution does not significantly improve the cleaning options.

Weiterhin ist eine Vakuumpresse bekannt, bei der die Preßschnecken aus dem Preßzylindern herausziehbar sind. Hierdurch wird zwar eine gute Zugänglichkeit der masseberührenden Teile möglich, jedoch ist ein relativ hoher konstruktiver und fertigungstechnischer Aufwand erforderlich.Furthermore, a vacuum press is known in which the press screws can be pulled out of the press cylinders. As a result, good accessibility to the Parts that come into contact with the earth are possible, but a relatively high level of design and manufacturing complexity is required.

Ziel der Erfindung ist es eine schnelle umfassende Reinigung von Vakuumpressen zugewährleisten.The aim of the invention is to ensure rapid, comprehensive cleaning of vacuum presses.

Der Erfindung liegt die Aufgabe zugrunde, durch eine optimale Zugänglichkeit, der mit der Masse in Beruhrung kommenden Pressenteile eine effektive Reinigung der selben zu ermöglichen.The object of the invention is to enable the press parts coming into contact with the mass to be effectively cleaned by optimum accessibility.

Erfindungsgemäß wird die gestellte Aufgabe dadurch gelöst, daß das Pressengehäuse aus verschwenkbaren Gehäuseelementen zusammengesetzt ist, die ihrerseits am Pressenrahmen angelenkt sind. Die horizontal klappbaren Zylinderhälften der Vorpresse sind über eine Flanschverbindung an einem gleichfalls horizontal schwenkbeweglich an einer U-förmigen Stütze des Pressenrahmens angeordneten Siebplattenhalter angeschlossen. Auf diesem ist anderenends eine Abdichtscheibe mit radialen und seitlichen Abdichtungsmitteln verschiebbar angeordnet. Die vertikal heb- und senkbare sowie horizontal schwenkbare Vakuumkammer ist über Schnellverschlüsse mit der Dichtscheibe lösbar verbunden. Die Verschwenkbarkeit der Vakuumkammer ist durch Gelenkverbindung mit der U-förmigen Stütze gewährleistet.According to the invention, the object is achieved in that the press housing is composed of pivotable housing elements which in turn are articulated on the press frame. The horizontally foldable cylinder halves of the pre-press are connected via a flange connection to a screen plate holder which is also pivotably horizontally arranged on a U-shaped support of the press frame. On the other end, a sealing washer with radial and lateral sealing means is slidably arranged. The vacuum chamber, which can be vertically raised and lowered and swiveled horizontally, is detachably connected to the sealing washer using quick-release fasteners. The pivoting of the vacuum chamber is guaranteed by a joint connection with the U-shaped support.

Die Vakuumkammer ist auf die Einfüllöffnung der Unterpresse aufgesetzt und mittels Schnellverschlüssen fixiert. Den Mischtrog von Unter- und Vorpresse bilden je zwei Gehauseelemente deren Innenwand der Kontur von Einräumer sowie Preßschnecke angepaßt und radial schwenkbar über vertikal verschiebbare Halterungen am Pressenrahmen angeschlossen sind.The vacuum chamber is placed on the filling opening of the lower press and fastened with quick-release fasteners. The mixing trough of the lower and the pre-press each form two housing elements, the inner wall of which is adapted to the contour of the scraper and the press screw and is connected to the press frame so that it can be pivoted radially via vertically displaceable brackets.

Diese besitzt ein radiales Abdichtelement 12 und stirnseitig ein zweites Abdichtelement 13, das die stirnseitige Abdichtung zur Vakuumkammer 1 gewährleistet. Diese ist mittels Schnellverschlüssen 14 an die Abdichtscheibe 6 anschließbar. Die Vakuumkammer 1 ist ihrerseits vertikal heb- und senkbar. ausgebildet, wozu ein zeichnerisch nicht dargestellter Exzenter dient. Durch die vertikale Bewegbarkeit der Vakuumkammer 1 wird eine Beschädigung der an der Unterseite der Vakuumkammer 1 angeordneten Dichtung beim Aufsetzen bzw. Abheben der Vakuumkammer 1 von der Zuführöffnung der Unterpresse vermieden. Für das horizontale Verschwenken besitzt die Vakuumkammer 1 Scharniere 15, die gleichfalls an der U-förmigen Stütze 7 angeschlossen sind.As can be seen from FIG. 1, the cylinder of the upper press is divided vertically into two cylinder halves 5.

Their dashed representation shows the cylinder halves 5 in the cleaning position.
At the end, the cylinder halves 5 have a flange part 4, which are detachably connected to the flange ring 8 of the screen plate holder 3 by means of quick-release fasteners known per se. For its part, the sieve plate holder 3 is also designed to be horizontally pivotable and is connected to a U-shaped support 7 of the press frame by means of a joint 16. A corresponding arrow shows the direction of rotation. The screen plate holder 3 shown in broken lines is in the cleaning position. On the side of the sieve plate holder 3 facing away from the flange ring 8, a sealing washer 6 is pushed on. This has a radial sealing element 12 and on the end face a second sealing element 13, which ensures the end seal on the vacuum chamber 1. This can be connected to the sealing disk 6 by means of quick fasteners 14. The vacuum chamber 1 can in turn be raised and lowered vertically. trained, for which purpose a cam, not shown, is used. The vertical mobility of the vacuum chamber 1 prevents damage to the seal arranged on the underside of the vacuum chamber 1 when the vacuum chamber 1 is placed or lifted off the feed opening of the lower press. For horizontal pivoting, the vacuum chamber 1 has hinges 15, which are also connected to the U-shaped support 7.
