Abstract

An arrangement for intensifying the mixing of material comprises a mixing tool worm unit.

Description

Diese Erfindung betrifft eine Vorrichtung zur Homogenisierung von Stoffgemischen.This invention relates to a device for homogenizing mixtures of substances.

Stand der TechnikState of the art

Mischer, speziell Tellermischer verkörpern einen hohen Stand der Technik (1). Zahlreiche Erfindungen zur Intensivierung des Mischprozesses beruhen auf einer zusätzlichen Verwirblung des Mischgutes. Die dazu bekannten Verfahren arbeiten mit Wirblerantriebsachsen und Wirblerbewegungen, die achsparallel zur Hauptantriebsachse stehen (2).Mixers, especially plate mixers, embody a high level of technology ( 1 ). Numerous inventions for intensifying the mixing process are based on an additional swirling of the mixture. The methods known for this work with vortex drive axes and vortex movements that are axially parallel to the main drive axis ( 2 ).

Nachteile des Standes der TechnikDisadvantages of the prior art

Die bekannten vertikalen Wirbler bringen eine Verkürzung der Mischzeit im Gegensatz zum konventionellen Mischer mit festen Mischwerkzeuge mit sich. Durch die Drehbewegung der Wirblerwerkzeuge erfolgt eine zusätzliche Durchmischung der einzelnen Medien aber nur in der horizontalen Ebene, so daß sich Bereiche ausbilden, in denen eine nur sehr mangelhafte Durchmischung des Gutes stattfindet.In contrast, the well-known vertical whirlers reduce the mixing time to the conventional mixer with fixed mixing tools. Through the Rotational movement of the swirler tools results in additional mixing of the individual media but only in the horizontal plane, so that areas form in for which there is only a very poor mixing of the goods.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es, durch die zusätzlichen Wirblerwerkzeuge den Mischprozeß zu intensivieren und die Mischzeit zu verkürzen. Diese Aufgabe wird durch die Vorrichtung mit den Merkmalen des Anspruches 1 gelöst.The object of the invention is the by the additional swirler tools Intensify the mixing process and shorten the mixing time. This task is accomplished by solved the device with the features of claim 1.

Vorteile der ErfindungAdvantages of the invention

  • - Gründliche Vermengung des Mischgutes in zwei benachbarten Ebenen (horizontal und vertikal) (3).- Thorough mixing of the mix in two adjacent levels (horizontal and vertical) ( 3 ).
  • - Vermeidung von Zonen mangelhafter Gemischhomogenisierung durch stetige Förderung des Mischgutes.- Avoid zones of poor mixture homogenization through constant Promotion of the mixed material.
  • - Durch einen abschaltbaren Schneckenantrieb ist gleichzeitig herkömmlicher Betrieb möglich, da durch die geringe Fläche einer Schnecke ein gutes Vorbeifließen des Gutes auch bei stillstehender Schnecke gewährleistet ist.- With a worm drive that can be switched off, it is also conventional operation possible because the small area of a snail allows the Good things are guaranteed even when the screw is at a standstill.
  • - Ein homogenes Gemisch wird in einer kürzeren Zeit erreicht.- A homogeneous mixture is achieved in a shorter time.
  • - Nachträgliche Montage der Wirblerkomponente mit geringem Aufwand in bereits ausgeführte konventionelle Tellermischer möglich.- Subsequent installation of the vortex component with little effort in already Executed conventional plate mixers possible.
Ausführungsbeschreibung der ErfindungEmbodiment description of the invention

Der Wirbler besteht aus einem Tragrahmen, an dem alle notwendigen Komponenten befestigt sind. Dieser Tragrahmen kann somit nachträglich in den Tellermischer eingebaut werden. Der Tragrahmen dient gleichzeitig zur Aufnahme der Abstreifer für die Innen- und Außenwand. Der Abstand des Außenrahmens von Innen- und Außenwand muß so gewählt werden, daß ein Verklemmen nicht möglich ist (Korngröße beachten).The swirler consists of a support frame on which all necessary components are attached are attached. This support frame can thus be retrofitted in the plate mixer to be built in. The support frame also serves to hold the wipers for the inner and outer wall. The distance of the outer frame from inside and The outer wall must be selected so that jamming is not possible (grain size note).

Als Antrieb dient wahlweise ein separater Elektromotor oder ein Getriebe. Bei mehr als einer Schnecke ist eine gegenläufige Drehrichtung sinnvoll. Je nach Mischgut eignen sich insbesondere die folgenden Schneckengrundformen: Vollschnecke, Bandschnecke und Paddelschnecke (Fig. 3).A separate electric motor or a gearbox is used as the drive. If there is more than one screw, an opposite direction of rotation makes sense. Depending on the mix, the following basic screw shapes are particularly suitable: full screw, belt screw and paddle screw ( Fig. 3).

Um einen gleichmäßigen Transport des Mischgutes in radialer Richtung zu gewährleisten, sollten auf einer Schneckenwelle zwei Schneckenwendel mit gegenläufiger Steigung angebracht sein (Fig. 4).In order to ensure a uniform transport of the mix in the radial direction, two worm coils with opposing pitch should be attached to a worm shaft ( Fig. 4).

Fig. 1 stellt den Einbau eines solchen Wirblers in der Vorderansicht dar, wobei (1) den Wirbler zeigt, (2) die vorhandenen Mischwerkzeuge im Tellermischer und (3) den Mischtrog des Mischers. Fig. 1 shows the installation of such a swirler in the front view, ( 1 ) showing the swirler, ( 2 ) the existing mixing tools in the plate mixer and ( 3 ) the mixing trough of the mixer.

Fig. 2 stellt die Draufsicht auf den in einen Tellermischer eingebauten Wirbler dar. Fig. 2 shows the top view of the built-in a plate mixer swirler.
