the preamble of
Chargenmischer zum Mischen fester oder plastischer fliessfähiger Stoffe oder Schüttgüter sind als allgemein bekannt anzusehen. Die US-A-4043540 offenbart einen kippbaren Paddelmischer mit, in einem Trog umlaufenden, spiralförmigen Mischelementen. Eine vergleichbare Konstruktion findet sich ebenfalls in den US-PS-4509860 und US-PS-3273863. Sie sind vor allem für trockenes Mischgut geeignet.Batch mixer for mixing solid or plastic flowable Substances or bulk goods are generally known. The US-A-4043540 discloses a tiltable paddle mixer with, in a trough surrounding spiral mixing elements. A comparable one Construction is also found in US-PS-4509860 and US-PS-3273863. They are particularly suitable for dry mix.
Ein Rührwerk zum Mischen von Futtermitteln nach DD-PS-262961 zeigt eine Mischtrommel mit einem horizontal angeordneten Rührwerk, an dem senkrecht stehende und gerade ausgebildete Rührwerksarmsegmente angeordnet sind, die an ihren Enden Mischleisten tragen. Mittig sind zwischen den Segmenten plattenförmige Zusatzmischwerkzeuge lösbar befestigt.A stirrer for mixing feed according to DD-PS-262961 shows a mixing drum with a horizontally arranged agitator the vertical and straight trained agitator arm segments are arranged, which carry mixing strips at their ends. Plate-shaped additional mixing tools are in the middle between the segments releasably attached.
Aus der CH-A-648767 ist ein Mischaggregat mit einem zylindrischen Mischbehälter bekannt. In diesem ist längsaxial und nahezu horizontal eine drehbare Mischerwelle angeordnet, an der Gruppen von Mischerarmen mit daran befindlichen Mischblechen befestigt sind. Die Wirkrichtung der Mischbleche ist gruppenweise entgegengesetzt.From CH-A-648767 is a mixing unit with a cylindrical Mixing container known. In this is longitudinal axial and almost horizontal a rotatable mixer shaft arranged on the groups of Mixer arms with attached mixing plates are attached. The direction of action of the mixing plates is opposite in groups.
Beim gegebenen Stand der Technik sind die Durchmesser-Längen-Verhältnisse der Mischbehälter sehr verschieden von eins. Es ist ebenso bekannt, derartige Mischer durch untenliegende Klappen schnell zu entleeren Solche Bodenklappen können über die gesamte Mischerlänge reichen und sind auch mit einer selbstsperrenden (gegen selbsttätiges Öffnen) Betätigung ausgerüstet. Given the state of the art, the diameter-length ratios are the mixing tank very different from one. It is also known to have such mixers through bottom flaps can be emptied quickly Mixer lengths are sufficient and are also available with a self-locking (against automatic opening) actuation equipped.
Für eine möglichst rückstandsarme Entleerung von Futtermischgut wurde bereits vorgeschlagen, geteilte Entleerklappen (Bodenklappen) vorzusehen. Der Tangentenwinkel soll hierbei grösser als der Schüttgutwinkel sein, was grosse Klappen erfordert. Zudem ist eine Luftabreinigung und eine aufwendige Oberflächenbehandlung des Mischerinnenraumes erforderlich.For a residue-free emptying of feed mix has already been proposed to split emptying flaps (Bottom flaps). The tangent angle should be here be larger than the bulk angle, which requires large flaps. In addition, there is air cleaning and a complex surface treatment of the mixer interior is required.
Hierzu wird weiterhin in der EP-A-142003 ein Betonmischer mit geteilten Bodenklappen offenbart, wobei der Betätigungsmechanismus für diese Doppelklappen kompliziert ist und die Drehpunkte der Klappen hoch angesetzt sind, was entsprechend grosse Klappenabmessungen bewirkt. Zur Kraftverstellung ist ein aufwendiges Unterlegen von Blechen erforderlich.For this purpose, a concrete mixer with divided parts is also used in EP-A-142003 Bottom flaps disclosed, the actuating mechanism for these double flaps is complicated and the pivot points of the Flaps are set high, which corresponds to large flap dimensions causes. To adjust the force is a complex underlay of sheets required.
Jede Klappe weist eine horizontale Klappenschmalseite, welche bei geschlossener Öffnungsklappe, wie z.B. im Fig. 3 gezeigt, sich an eine dazu passende Gegenschräge an der Gehäuseöffnung anlegt. Wenn die beiden Klappen, wie in Fig. 4 gezeigt, in einer Schliessstellung liegen, wird diese mit einer Dichtungsleiste, die am Gehäuse und der Gegenschräge benachbart angeordnet ist, gesichert. Die Dichtungsleiste ist in eine Nut eingelassen, die mittels zwei Schrauben an jeder Klappe befestigt ist, so dass gegenseitiges Verschieben bzw. Reibungen der Platten ausgeschlossen sind. Dieses Vorgehen ist zeitaufwendig.Each flap has a horizontal narrow flap side, which at closed opening flap, e.g. shown in Fig. 3 itself creates a matching counter bevel at the housing opening. If the two flaps, as shown in Fig. 4, in one Closed position, this is with a sealing strip, which is arranged adjacent to the housing and the counter slope, secured. The sealing strip is embedded in a groove that is attached to each flap by means of two screws, so that mutual Moving or friction of the plates excluded are. This is time consuming.
