Description

Die Erfindung betrifft einen Konus-Schneckenmischer nach dem Oberbegriff des Patentanspruchs 1. Derartige Konus-Schneckenmischer sind in vielfältigen Ausführungsformen bekannt geworden. Allen bekannten Ausführungsformen ist gemeinsam, daß der Mischbehälter fest an einem Grundrahmen befestigt ist und daß der Mischbehälter nach oben durch einen Behälterdeckel abgeschlossen ist, wobei im Behälterdeckel der Dreh- und Schwenkantrieb für die Mischschnecke befestigt ist. In bekannter Weise münden vom Behälterdeckel aus vielfältige Einführungsöffnungen in den Mischbehälter, zum Beispiel die Leitungen für die Vakuum-Erzeugung, die Leitungen für die Beheizung des Behälterdeckels und dergleichen mehr, wobei eine Vielzahl von zusätzlichen Aggregaten auf dem Behälterdeckel befestigt sind.The invention relates to a cone screw mixer according to the preamble of claim 1. Cone screw mixers of this type have become known in various embodiments. All known embodiments have in common that the mixing container is fixedly attached to a base frame and that the mixing container is closed at the top by a container lid, the rotary and pivoting drive for the mixing screw being fastened in the container lid. In a known manner, diverse inlet openings, for example the lines for vacuum generation, the lines for heating the container lid and the like, open out from the container lid, with a large number of additional units being fastened to the container lid.

Bisher war es praktisch nicht möglich, den Mischbehälter eines derartigen Konus-Schneckenmischers auf befriedigende Art von innen zu reinigen. Bisher mußte man den unteren Auslauf entfernen, um von dort aus mit entsprechenden Reinigungs-Instrumenten in das Innere des Mischbehälters vorzudringen und um dort eine Reinigung zu versuchen, was wegen der unzugänglichen Raumverhältnisse nur ungenügend gelang.So far it has been practically impossible to clean the inside of the mixing container of such a cone screw mixer in a satisfactory manner. Previously, one had to remove the lower spout in order to penetrate into the interior of the mixing container with appropriate cleaning instruments and to try cleaning there, which was only insufficient due to the inaccessible space.

Ebenso war es bekannt, den Deckel vollständig abzubauen und nach oben hin abzuheben, was sehr umständlich und schwierig ist, denn es mußten dann sämtliche Zuleitungen für die auf dem Deckel befestigten Aggregate entfernt werden, um den Deckel vom Mischbehälter abheben zu können.It was also known to completely dismantle the lid and lift it upwards, which is very cumbersome and difficult, because then all supply lines for the units attached to the lid had to be removed in order to be able to lift the lid off the mixing container.

Bei großen Mischbehältern ist es ferner bekannt, im Mischbehälter ein Mannloch anzubringen, damit durch diese Reinigungsöffnung eine Person in das Innere des Mischbehälters gelangen kann, um dort die Reinigung vorzunehmen. Diese Art der Reinigung ist jedoch umständlich und unfallgefährlich.In the case of large mixing containers, it is also known to provide a manhole in the mixing container so that a person can get into the interior of the mixing container through this cleaning opening in order to carry out the cleaning there. However, this type of cleaning is cumbersome and dangerous.

Der Erfindung liegt die Aufgabe zugrunde, einen Konus-Schneckenmischer der eingangs genannten Art so weiterzubilden, daß sein Inneres leicht zugänglich gemacht werden kann.The invention has for its object to develop a cone screw mixer of the type mentioned so that its interior can be made easily accessible.

Zur Lösung der gestellten Aufgabe ist die Erfindung dadurch gekennzeichnet, daß der Behälterdeckel in dem Grundrahmen befestigt ist und mit dem Mischbehälter über Schnellverschlußelemente verbunden ist, und daß der Mischbehälter mit einer Hubeinrichtung vertikal verstellbar im Grundrahmen angeordnet ist.To achieve the object, the invention is characterized in that the container lid is fastened in the base frame and is connected to the mixing container by means of quick-release elements, and that the mixing container is arranged in the base frame in a vertically adjustable manner.

Merkmal der vorliegenden Erfindung ist also, daß nun der Behälterdeckel fest mit dem Grundrahmen verbunden ist und der Mischbehälter über eine motorisch oder handbetätigbare Hubeinrichtung vertikal von dem fest im Grundrahmen gehaltenen Behälterdeckel absenkbar ist.A feature of the present invention is that the container lid is now firmly connected to the base frame and the mixing container can be lowered vertically from the container lid firmly held in the base frame by means of a motorized or manually operated lifting device.

Mit dieser Ausführungsform ergeben sich vielfältige Vorteile gegenüber den bekannten Anordnungen. Zunächst ist ein derartig absenkbarer Mischbehälter vor allem für Konus-Schneckenmischer verwendbar, die für Versuchszwecke (zum Mischen kleiner Chargen) vorgesehen sind. Mit dem vertikal absenkbaren Mischbehälter ist dann eine einfache Überprüfung des Versuchsergebnisses möglich, denn durch Lösen der Schnellverschlußelemente und Betätigung der Hubeinrichtung kann der Mischbehälter auf einfache Weise vom Behälterdeckel nach unten abgesenkt werden, und der Inhalt des Mischbehälters ist nun einer optischen Überprüfung einfach zugänglich.With this embodiment there are many advantages over the known arrangements. First of all, a mixing container that can be lowered in this way can be used above all for cone screw mixers which are intended for experimental purposes (for mixing small batches). A simple check of the test result is then possible with the vertically lowerable mixing container, because by loosening the quick-release elements and actuating the lifting device, the mixing container can easily be lowered from the container lid, and the contents of the mixing container are now easily accessible for visual inspection.

Die Reinigung geschieht genauso einfach, denn es kann sowohl eine Reinigung von oben erfolgen, als auch eine Reinigung von unten.Cleaning is just as easy, because it can be cleaned from above as well as from below.

In einer Weiterbildung der vorliegenden Erfindung ist es vorgesehen, daß der Mischbehälter in seiner abgesenkten Stellung in einer horizontalen Achse schwenkbar ausgebildet ist. Auf diese Weise ist es einfach möglich, den Behälterinhalt zu entfernen und die Reinigung des Mischbehälters wird hierdurch noch weiter erleichtert.In a further development of the present invention, it is provided that the mixing container is designed to be pivotable in a horizontal axis in its lowered position. In this way, it is easily possible to remove the contents of the container and cleaning of the mixing container is thereby made even easier.

Die erfindungsgemäße Hubeinrichtung zum Absenken des Mischbehälters kann auf verschiedene Weise ausgebildet sein.The lifting device according to the invention for lowering the mixing container can be designed in various ways.

Eine erste Ausführungsform sieht vor, daß am Grundrahmen eine vertikale Zahnstange befestigt ist, mit der ein über eine Handkurbel drehend angetriebenes Antriebsrad kämmt, welches Teil eines Hubgetriebes ist, welches mit dem Mischbehälter verbunden ist. Das Gehäuse des Hubgetriebes ist hierbei mit einer Anschweiß-Konsole verbunden, welche ihrerseits fest mit dem Außenumfang des Mischbehälters verbunden ist. Durch Drehung des Antriebsrades, z.B. über die Handkurbel oder über einen Elektromotor, verschiebt sich dann das Hubgetriebe längs der Zahnstange, wonach der Mischbehälter in gleicher Weise angehoben oder abgesenkt wird.A first embodiment provides that a vertical toothed rack is attached to the base frame, with which a drive wheel, which is driven in rotation via a hand crank, meshes, which is part of a lifting gear, which is connected to the mixing container. The housing of the lifting gear is connected to a welding bracket, which in turn is firmly connected to the outer circumference of the mixing container. By turning the drive wheel, e.g. The lifting gear then moves along the rack via the hand crank or via an electric motor, after which the mixing container is raised or lowered in the same way.

Eine derartige Ausführungsform mit einer einfachen Zahnstange wird man nur für leichte Mischbehälter bis zu einem Nutzinhalt von beispielsweise 50 1 verwenden, während man bei größeren Mischbehältern eine zweiseitige Hubeinrichtung verwendet, wo also bei einander gegenüberliegenden Seiten des Grundrahmens jeweils eine Zahnstange angeordnet ist, der jeweils eine Hubeinrichtung zugeorndet ist, die synchron über einen Handantrieb oder über einen Motorantrieb betätigt wird.Such an embodiment with a simple rack will only be used for light mixing containers up to a useful content of, for example, 50 liters, while for larger mixing containers a two-sided lifting device is used, where a rack is arranged on opposite sides of the base frame, each one Lifting device is assigned, which is operated synchronously via a manual drive or a motor drive.

Statt des hier vorgeschlagenen Zahnstangen-Antriebes ist in einer zweiten Ausführungsform vorgesehen, die Hubeinrichtung als motorisch angetriebene Drehspindel auszubilden, die mit einer fest mit dem Mischbehälter verbundenen Spindelmutter kämmt.Instead of the rack and pinion drive proposed here, it is provided in a second embodiment to design the lifting device as a motor-driven rotating spindle which meshes with a spindle nut which is firmly connected to the mixing container.

Eine weitere Ausführungsform sieht vor, daß der Mischbehälter in dem Grundrahmen über eine Windeneinrichtung anhebbar und absenkbar ist, wobei die Windeneinrichtung in bekannter Weise mit einem Klinkengesperre ausgebildet ist oder auch selbsthemmend ausgebildet ist.A further embodiment provides that the mixing container can be raised and lowered in the base frame by means of a winch device, the winch device being designed in a known manner with a ratchet mechanism or also being designed to be self-locking.

Neben derartigen mechanischen Hubvorrichtungen ist es nach dem Erfindungsgedanken der vorliegenden Erfindung auch vorgesehen, eine derartige Hubeinrichtung entweder als pneumatisch betätigten Hubzylinder oder auch als hydraulisch betätigten Hubzylinder auszubilden.In addition to such mechanical lifting devices, it is also provided according to the inventive concept of the present invention to design such a lifting device either as a pneumatically operated lifting cylinder or also as a hydraulically operated lifting cylinder.

Weitere Merkmale der Erfindung sind Gegenstand der übrigen Unteransprüche.Further features of the invention are the subject of the remaining subclaims.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

Alle in den Unterlagen offenbarten Angaben und Merkmale, insbesondere die in den Zeichnungen dargestellte, räumliche Ausbildung werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All of the information and features disclosed in the documents, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are new to the prior art, individually or in combination.

Im folgenden wird die Erfindung anhand von mehrere Ausführungswege darstellenden Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere erfindungswesentliche Merkmale und Vorteile der Erfindung hervor.In the following, the invention will be explained in more detail with reference to drawings showing several possible embodiments. Further features and advantages of the invention which are essential to the invention emerge from the drawings and their description.

Es zeigen:

  • Figur 1: schematisiert gezeichnete Seitenansicht eines Konus-Schneckenmischers in Betriebsstellung,
  • Figur 2: eine um 90° gedrehte Seitenansicht im Vergleich zu Figur 1,
  • Figur 3: die gleiche Darstellung wie Figur 1 mit abgesenktem Mischbehälter,
  • Figur 4: eine weitere Ausführungsform eines Konus-Schneckenmischers.
Show it:
  • FIG. 1: schematically drawn side view of a cone screw mixer in the operating position,
  • FIG. 2: a side view rotated by 90 ° compared to FIG. 1,
  • FIG. 3: the same representation as FIG. 1 with the mixing container lowered,
  • Figure 4: a further embodiment of a cone screw mixer.

In Figur 1 ist der Behälterdeckel 4 des Konus-Schneckenmischers fest an der Oberseite eines Grundrahmens 5 mit Hilfe von nicht näher dargestellten Verschraubungen befestigt. An der Oberseite des Behälterdeckels 4 ist der zweifache Antrieb 1 für den Dreh- und Schwenkantrieb des Schwenkarmes 2 (vergleiche Figur 3) vorgesehen.In Figure 1, the container lid 4 of the conical screw mixer is fixedly attached to the top of a base frame 5 by means of screw connections, not shown. At the top of the container lid 4, the double drive 1 is provided for the rotary and swivel drive of the swivel arm 2 (see FIG. 3).

Der Schwenkarm 2 wird hierbei um eine vertikale Achse drehend angetrieben, während die am äußeren schwenkbaren Ende des Schwenkarmes 2 gelagerte Mischschnecke 3 um ihre Längsachse ebenfalls drehend angetrieben wird. Auf diese Weise führt die Mischschnecke 3 eine Bewegung parallel zur Innenwandung des konischen Mischbehälters 6 aus.The swivel arm 2 is in this case driven in rotation about a vertical axis, while the mixing screw 3 mounted on the outer pivotable end of the swivel arm 2 is also driven in rotation around its longitudinal axis. In this way, the mixing screw 3 executes a movement parallel to the inner wall of the conical mixing container 6.

In nicht näher dargestellter Weise sind auf dem Behälterdeckel 4 noch weitere Aggregate angeordnet, wie z.B. Zuleitungen für die Beheizung des Behälterdeckels, Vakuumleitungen, Filter und dergleichen.In a manner not shown, further units are arranged on the container lid 4, e.g. Supply lines for heating the container lid, vacuum lines, filters and the like.

Im gezeigten Ausführungsbeispiel ist der Mischbehälter 6 über Schnellverschlußelemente 7 leicht lösbar mit dem Behälterdeckel 4 verbunden.In the exemplary embodiment shown, the mixing container 6 is connected to the container lid 4 in an easily detachable manner via quick-release elements 7.

In einer bevorzugten Ausführungsform besteht jedes Schnellverschlußelement aus einem schwenkbar am Außenumfang des Mischbehälters 6 gelagerten Spannbügel, an dessen oberem Ende eine Gewindebohrung angebracht ist, in der eine Klemmschraube sitzt. Das bolzenseitige Ende der Klemmschraube drückt hierbei in gespanntem Zustand des Schnellverschlußelementes 7 auf die Oberseite des Behälterdeckels 4. Zum Lösen dieses Schnellverschlußelementes 7 wird die Spannschraube zunächst um einige Umdrehungen gelöst, wonach sie außer Eingriff mit dem Behälterdeckel 4 kommt und der Spannbügel kann dann vom Behälterdeckel weggeschwenkt werden, wodurch die Verbindung zwischen dem-Mischbehälter 6 und dem Behälterdeckel 4 aufgehoben ist.In a preferred embodiment, each quick-release element consists of a swivel bracket which is pivotably mounted on the outer circumference of the mixing container 6 and at the upper end of which a threaded bore is made in which a clamping screw is seated. The bolt-side end of the clamping screw presses in the tensioned state of the quick release element 7 on the top of the container lid 4. To release this quick release element 7, the clamping screw is first loosened by a few turns, after which it disengages from the container lid 4 and the clamping bracket can then be removed from the container lid be pivoted away, whereby the connection between the mixing container 6 and the container lid 4 is broken.

Zur Absenkung des Mischbehälters 6 in die in Figur 3 gezeigte Stellung ist eine Hubeinrichtung 8 vorgesehen, die in einem bevorzugten Ausführungsbeispiel aus einem Hubgetriebe 17 besteht, dessen Antriebsrad über eine Handkurbel 12 drehend angetrieben ist, und wobei dieses nicht näher dargestellte Antriebsrad mit der Verzahnung einer vertikalen Zahnstange 11 kämmt, welche fest im Grundrahmen 5 befestigt ist.In order to lower the mixing container 6 into the position shown in FIG. 3, a lifting device 8 is provided, which in a preferred embodiment consists of a lifting gear 17, the drive wheel of which is driven in rotation by means of a hand crank 12, and this drive wheel (not shown in more detail) with the teeth of one combs vertical rack 11 which is fixedly attached to the base frame 5.

Das Gehäuse des Hubgetriebes 17 ist mit einer Anschweiß- konsole 10 verbunden, welche ihrerseits fest mit dem Außenumfang des Mischbehälters 6 verbunden ist.The housing of the lifting gear 17 is connected to a welding bracket 10, which in turn is firmly connected to the outer circumference of the mixing container 6.

Mit Drehung der Handkurbel 12 kann daher der Mischbehälter 6 in seine untere, abgesenkte Stellung nach Figur 3 gebracht werden. Es ist nun eine einfache Reinigung möglich, denn man kann den Inhalt des Mischbehälters von oben her optisch kontrollieren und die Reinigung erfolgt von oben, wobei dann bei geöffnetem Auslauf 9 die Reinigungsflüssigkeit entfernt werden kann.By rotating the hand crank 12, the mixing container 6 can therefore be brought into its lower, lowered position according to FIG. 3. Simple cleaning is now possible because the contents of the mixing container can be checked optically from above and cleaning takes place from above, the cleaning liquid then being able to be removed when the outlet 9 is open.

In einer Weiterbildung der vorliegenden Erfindung ist es zusätzlich vorgesehen, daß zwischen dem Gehäuse des Hubgetriebes 17 und der Anschweißkonsole 10 ein Schwenklager 16 vorgesehen ist, so daß in der abgesenkten Stellung der Mischbehälter 6 um die Schwenkachse 15 verschwenkbar ist. Voraussetzung hierbei ist, daß er soweit abgesenkt werden kann, daß die Mischschnecke 3 ein Verschwenken in der Schwenkachse 15 nicht behindert.In a development of the present invention, it is additionally provided that a pivot bearing 16 is provided between the housing of the lifting gear 17 and the welding bracket 10, so that the mixing container 6 can be pivoted about the pivot axis 15 in the lowered position. The prerequisite here is that it can be lowered so far that the mixing screw 3 does not hinder pivoting in the pivot axis 15.

In der Figur 2 sind die gleichen Teile mit den gleichen Bezugszeichen versehen.In Figure 2, the same parts are provided with the same reference numerals.

Die Figur 4 zeigt ein abgewandeltes Ausführungsbeispiel, das sich von dem vorher beschriebenen Ausführungsbeispiel dadurch unterscheidet, daß die Hubeinrichtung 18 aus einer über einen Motor 13 drehend angetriebenen Spindel 14 besteht, die mit einer nicht näher dargestellten Spindelmutter kämmt, die fest mit dem Mischbehälter 6 verbunden ist. Ansonsten gelten für die funktionell gleichen Teile die gleichen Bezugszahlen.FIG. 4 shows a modified exemplary embodiment, which differs from the previously described exemplary embodiment in that the lifting device 18 consists of a spindle 14 which is driven in rotation by a motor 13 and which meshes with a spindle nut (not shown in more detail) which is fixedly connected to the mixing container 6 is. Otherwise, the same reference numbers apply to the functionally identical parts.

Statt der hier beschriebenen, einseitig angeordneten Hubeinrichtungen 8,18 können selbstverständlich auch zweiseitig im Grundrahmen 5 befestigte Hubeinrichtungen vorgesehen werden; derartige Hubeinrichtungen werden vor allem für Mischbehälter mit größerem Nutzvolumen verwendet.Instead of the lifting devices 8, 18 arranged here on one side, lifting devices which are fastened on two sides in the base frame 5 can of course also be provided; Such lifting devices are used primarily for mixing containers with a larger usable volume.

Neben der Ausbildung der Schnellverschlußelemente 17 als Schwenkklammerschrauben ist es in einer Alternative vorgesehen, derartige Schnellverschlußelemente als bekannte Kniehebelverschlüsse auszubilden.In addition to the design of the quick-release fastener elements 17 as swivel clamp screws, it is provided in an alternative to design such quick-release fastener elements as known toggle lever fasteners.

Eine weitere Möglichkeit der lösbaren Verbindung zwischen Behälterdeckel 4 und Mischbehälter 6 ergibt sich durch Ausbildung dieses Schnellverschlußelementes 6 als Bajonettverschluß. In diesem Fall sind sowohl am Behälterdeckel als auch an der Außenseite des Mischbehälters radial auswärts stehende Lappen vorgesehen, die in Schließstellung genau übereinanderliegen und mit einem von außen her aufschiebbaren und mit einem Steilgewinde versehenen und damit aufdrehbaren Klemmring zusammengehalten werden.Another possibility of the detachable connection between the container lid 4 and the mixing container 6 results from the design of this quick-locking element 6 as a bayonet fitting. In this case, both on the container lid as well as on the outside of the mixing container radially outward-standing tabs which are exactly one above the other in the closed position and are held together with a clamping ring which can be pushed on from the outside and provided with a steep thread and thus rotated.
