Abstract
Description
Die Erfindung betrifft eine Extrudereinrichtung mit einem Doppelschneckenextruder mit zwei gleichsinnig drehenden und miteinander kämmenden Schnecken gemäß dem Oberbegriff von Anspruch 1. Die Erfindung betrifft desweiteren eine mit einer derartigen Extrudereinrichtung ausgestattete Compounder-Spritzgießmaschine.The invention relates to an extruder device with a twin-screw extruder with two co-rotating and intermeshing screws according to the preamble of claim 1. The invention further relates to a equipped with such an extruder compounder injection molding machine.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine weitere Extrudereinrichtung anzugeben, die trotz ihrer konstruktiven Ausgestaltung einen Druckaufbau am Materialaustrag ergibt, ohne dass es in der Extrudereinrichtung selbst zu einem signifikanten Rückstau kommt, wenn diese Extrudereinrichtung für spezielle Anwendungen verwendet wird.Based on this prior art, the present invention seeks to provide a further extruder device, which results despite its structural design, a pressure build-up at the material discharge, without it comes in the extruder itself to a significant backlog when this extruder device is used for special applications ,
Die Lösung dieser Aufgabe erfolgt durch eine Extrudereinrichtung mit den Merkmalen von Anspruch 1. Vorteilhafte Ausgestaltungen und Weiterentwicklungen finden sich in den Unteransprüchen.The solution of this object is achieved by an extruder device with the features of claim 1. Advantageous embodiments and further developments can be found in the subclaims.
Obwohl der Gangquerschnitt in der Austragsschnecke kleiner oder gleich ist wie der Gangquerschnitt bei der Schnecke des Doppelschneckenextruders, kann es gleichwohl nicht zu einem nennenswerten Rückstau bzw. einem nennenswerten Staudruck am vorderen Ende des Doppelschenckenextruders kommen, wenn dieser in geeigneter Weise unterfüttert betrieben wird. Je nach Anwendungsfall kann es nämlich erforderlich sein, dass der Doppelschneckenextruder mehr oder weniger stark unterfüttert betrieben wird. Dies bedeutet, dass die aktuelle Förderleistung des Doppelschneckenextruders deutlich kleiner ist als die konstruktiv mögliche maximale Förderleistung. Vorzugsweise soll die aktuelle Förderleistung 10% bis 50% der maximal möglichen Förderleistung betragen. Dies bedeutet, dass der Füllgrad in den Schneckengängen des Doppelschneckenextruders nur etwa 10% bis 30% beträgt, d. h. der Gangquerschnitt in den Schneckengängen des Doppelschneckenextruders ist nur zu etwa 10% bis 30% gefüllt. Dies gilt jedoch nur für diejenigen Zonen des Doppelschneckenextruders, in denen ein reiner Materialtransport erfolgt, und somit nicht für solche Bereiche, in denen Druck zum Überfahren von Mischzonen oder dergleichen aufgebaut werden muss. In diesen Bereichen liegt der Füllgrad deutlich höher und beträgt in der Regel sogar 100%.Although the passage cross-section in the discharge screw is less than or equal to the passage cross-section in the screw of the twin-screw extruder, it can nevertheless not come to a significant backwater or a significant back pressure at the front end of the twin-leg extruder, if it is operated underfed suitably. Depending on the application, it may in fact be necessary for the twin-screw extruder to be operated more or less underfed. This means that the current delivery rate of the twin-screw extruder is significantly smaller than the constructively possible maximum delivery rate. Preferably, the current capacity should be 10% to 50% of the maximum possible capacity. This means that the degree of filling in the screw flights of the twin-screw extruder is only about 10% to 30%, d. H. the passage cross-section in the flights of the twin-screw extruder is only about 10% to 30% full. However, this applies only to those zones of the twin-screw extruder in which a pure material transport takes place, and thus not for those areas in which pressure must be built up to drive over mixing zones or the like. In these areas, the degree of filling is significantly higher and is usually even 100%.
Durch die Ausgestaltung der Extrudereinrichtung mit wenigstens einem erfindungsgemäßen Einschneckenextruder-Element wird gleichwohl erreicht, dass am vorderen Ende des Einschneckenextruder-Elements ein Druck erzielt werden kann, wie er von dem Doppelschneckenextruder allein unter gleichen Betriebsbedingungen nicht erzielbar ist. Vielmehr wird der Wirkungsgrad beim Druckaufbau durch das Einschneckensystem signifikant erhöht. Die vom Antrieb in den gleichsinnig drehenden Doppelschneckenextruder eingebrachte Energie wird real nur zu etwa 8–10% in Druckaufbau umgesetzt. Dieser Wirkungsgrad wird durch die Erfindung mehr als verdoppelt.The design of the extruder device with at least one Einschneckenextruder element according to the invention is nevertheless achieved that at the front end of the Einschneckenextruder element, a pressure can be achieved, as he of the twin-screw extruder alone below same operating conditions is not achievable. Rather, the efficiency in the pressure build-up is significantly increased by the single-screw system. The introduced by the drive in the co-rotating twin-screw extruder energy is actually converted only about 8-10% in pressure build-up. This efficiency is more than doubled by the invention.
In vorteilhafter Weise kann der Gangquerschnitt der Austragsschnecke in Richtung der Austragsöffnung der Extrudereinrichtung abnehmen. Die Schnecken des Doppelschneckenextruders können anstelle von jeweils einem Schneckengang auch jeweils zwei oder mehr Schneckengänge aufweisen, wobei in einem solchen Falle der Gangquerschnitt der Austragsschnecke gleich oder kleiner ist wie die Summe der Gangquerschnitte der Schneckengänge bei einer Schnecke des Doppelschneckenextruders. Ebenso kann die Austragsschnecke anstelle von einem Schneckengang zwei oder mehr Schneckengänge aufweisen, wobei dann die Summe der Gangquerschnitte der Schneckengänge der Austragsschnecke gleich oder kleiner ist wie der Gangquerschnitt bei einer Schnecke des Doppelschneckenextruders. Die beiden vorgenannten Ausführungsformen können auch miteinander kombiniert werden, d. h. sowohl bei der Austragsschnecke als auch bei den Schnecken des Doppelschneckenextruders können mehrere Schneckengänge vorgesehen werden, wobei die Anzahl der Schneckengänge bei der Austragsschnecke einerseits und bei den Schnecken des Doppelschneckenextruders andererseits unterschiedlich sein kann. Eine einfache konstruktive Ausgestaltung ergibt sich, wenn der Kerndurchmesser der Austragsschnecke an der dem Doppelschneckenextruder zugewandten Ende der Austragsschnecke gleich groß ist wie der Kerndurchmesser einer Schnecke des Doppelschneckenextruders. In diesem Fall wird der Kerndurchmesser der Schnecke des Doppelschneckenextruders unverändert „fortgeführt”.Advantageously, the passage cross-section of the discharge screw can decrease in the direction of the discharge opening of the extruder device. The worms of the twin-screw extruder can also have two or more worm threads instead of one worm thread in each case, in which case the cross section of the discharge screw is equal to or smaller than the sum of the cross sections of the worm threads in a worm of the twin-screw extruder. Likewise, the discharge screw may have two or more flights instead of one flight, in which case the sum of the passage cross sections of the flights of the discharge screw is equal to or smaller than the passage cross section in a screw of the twin screw extruder. The two aforementioned embodiments can also be combined with each other, d. H. Several screw flights can be provided both in the discharge screw and in the screws of the twin-screw extruder, with the number of screw flights on the discharge screw on the one hand and on the screws of the twin-screw extruder on the other hand being different. A simple structural embodiment results when the core diameter of the discharge screw at the end of the discharge screw facing the twin-screw extruder is the same size as the core diameter of a screw of the twin-screw extruder. In this case, the core diameter of the screw of the twin-screw extruder is "continued" unchanged.
