Description

Diskontinuierlich arbeitende Misch- mid Knetmaschine für Kautschuk- und KunststoffmassenDiscontinuous mixing and kneading machine for rubber and plastic compounds

Die Erfindung "bezieht sich auf eine Heiz- und Kühlvorrichtung Ton diskontinuierlich, arbeitenden Misch- und Knetmaschinen für Kautschuk- und Kunststoff massen, mit einer einteiligen, im Maschinenständer auswechserbar angeordneten s lemniskatenförmigen Mischkammer.The invention "refers to a heating and cooling device clay discontinuously operating mixing and kneading machine for rubber and plastic masses, with a one-piece, in the machine stand auswechserbar s arranged lemniskatenförmigen mixing chamber.

Die "bekannten Heiz- und Kühlvorrichtungen dieser Art dienen dazus durch Wärmebeeinflussung einen günstigen Ablauf des Mischprozesses zu erreichen.The "known heating and cooling devices of this type are used in addition, by the influence of heat, a favorable expiry of the To achieve the mixing process.

Bei diesen Heiz- und Kühlvorrichtungen ist der Mischkammermantel als Hohlkörper ausgebildet« In diesem Hohlraum befindet sich eine im Abstand vom Mischkammermantel angeordnete und der Misehkammerform angepaßte Rohrleitung, welche mit Düsen versehen ist? aus denen das Heiz- bzw. Kühlmittel auf die äußere Mantelfläche der Mischkammer gespritzt wird, um diese nach Bedarf erwärmen oder kühlen zu können«, Da das Heiz- und Kühlmittel keinem Zwangsumlauf unterworfen ist, ist die gesamte Heizung oder Kühlung der Mischkammer schwierig beh.errsch.baro Die Polge ist, daß trotz der Kühlvorrieh.-tung örtliche Überh.itzungen in der Mischkammer auftreten können„In these heating and cooling devices, the mixing chamber jacket is designed as a hollow body. In this cavity there is a spaced apart from the mixing chamber jacket and pipeline adapted to the shape of the mixing chamber, which with Is provided with nozzles? from which the heating or cooling medium is based the outer jacket surface of the mixing chamber is injected in order to be able to heat or cool it as required «, Da das Heating and cooling medium is not subject to forced circulation, The entire heating or cooling of the mixing chamber is difficult to control. The main thing is that despite the cooling device Local overheating can occur in the mixing chamber be able"

Der Erfindung liegt die Aufgabe zugrunde, eine Heiz- und Kühlvorrichtung für diskontinuierlich arbeitende Misch- und Knetmaschinen zu schaffen! welche diesen Mangel der bekannten Einrichtung vermeidet.The invention is based on the object of creating a heating and cooling device for batchwise mixing and kneading machines! which this lack of known Establishment avoids.

Gelöst wird diese Aufgabe gemäß der Erfindung dadurch, daß mehrere im Mantel der Mischkammer axial verlaufende Durchflußbohrungen angeordnet sindj deren Mündungen auf beiden Mischkammerstirnflachen durch bogenförmige, mit Ausnehmungen versehene Leisten so überbrückt sind, daß die "Durchflußbohrungen nacheinander vom Heiz- bzw« Kühlmittel durchflossen werden.This object is achieved according to the invention in that several axially extending flow bores in the jacket of the mixing chamber their mouths are arranged on both mixing chamber faces by arched, recessed Bars are bridged so that the "flow bores are flowed through one after the other by the heating or coolant.

Die durch die Erfindung vorgeschlagene Anordnung der Durch— flußbohrungen gewährleistet überhaupt erst die Möglichkeit eines einfachen und besonders wirksamen Heiz- und Kühlmittelverlaufes an exponierten Stellen., wie im Mischkammer satt el der Mischkammer..The arrangement proposed by the invention of the through- Flow drilling guarantees the possibility of a simple and particularly effective heating and coolant flow in exposed places.

Zur thermischen Beherrschung des Misch- und Knet vor ganges in der Mischkammer einer diskontinuierlich arbeitenden Misch- und Knetmaschine ist der Kammermantel mit einer Heiz- oder Kühlvorrichtung versehen.For thermal control of the mixing and kneading process in the mixing chamber of a discontinuously working mixing and kneading machine, the chamber jacket is provided with a heating or cooling device.

Die Mischkammer 1 ist ungeteilt ausgeführt und als selbständiges Sinzelbauteil nach vorne herausziehbar angeordnet. Die Zuführ des Heiz- und Kühlmittels erfolgt durch eine Rohrleitung, die an eine im Sattel 2 axial verlaufende Zentralbohrung 3 an der Rückwandseite der Mischkammer 1 angeschlossen ist. Diese Zentralbohrung 3 weist, da insbesondere im Mischkammer satt el 2 sehr hohe !Temperaturen auftreten, einen wesentlich größeren Durehflußquersehnitt auf und dient als Zuführungsleitung für das Heiz- und Kühlmittel. Dieses verzweigt sich am Ende der Zentralbohrung 3 in einem linken und rechten Teil und durchfließt dann mehrere im Mantel 4 der Mischkammer 1 angeordnete, axial verlaufende und über den Kammerumfang verteilte Durchflußbohrungen 5, deren Durchflußguerschnitt entsprechend kleiner bemessen ist als der Querschnitt der Zentralbohrung 3» The mixing chamber 1 is designed to be undivided and is arranged as an independent single component so that it can be pulled out to the front. The heating and cooling agent is supplied through a pipeline which is connected to a central bore 3 running axially in the saddle 2 on the rear wall side of the mixing chamber 1. This central bore 3 has, since very high temperatures occur in particular in the mixing chamber satt el 2, a substantially larger flow cross section and serves as a supply line for the heating and cooling medium. This branches off at the end of the central bore 3 in a left and right part and then flows through several axially extending flow bores 5 arranged in the jacket 4 of the mixing chamber 1 and distributed over the chamber circumference, the flow cross section of which is correspondingly smaller than the cross section of the central bore 3 »

Die Mündungen dieser Durchflußbohrungen 5 sind durch an der vorderen und hinteren Stirnseite der Mischkammer 1 angeordnete kreisbogenförmige Leisten 6, die Ausnehmungen 7 aufweisen? abgedeckt. Die Ausnehmungen 7 dieser leisten 6 verbinden jeweils zwei benachbarte Durehflußbohrungen 5» Hierdurch entsteht ein mäanderförmiger Yerlauf des Heiz- und Kühlsystems ο ■ ' - 4 -The mouths of these flow bores 5 are arranged on the front and rear face of the mixing chamber 1 by circular arc-shaped strips 6 which have recesses 7 ? covered. The recesses 7 of these strips 6 each connect two adjacent through-flow bores 5 »This creates a meandering course of the heating and cooling system ο ■ '- 4 -
