Description

Bei deT Verarbeitung .verschiedener Fördermittef in den bekannten zwei- oder mehrspindeligen Schraubenpumpen ist es vielfach notwendig, das Gut zum Zweck einer intensiven Beheizung, Kühlung oder sonstigen Durcharbeitürig, vor allem plastischer Massen, längere Zeit im Förderraum zu belassen.-Eine Verlängerung der Arbeitsschrauben' um ein Vielfaches ist meist nicht ausreichend und andererseits wegen der zu großen Durchbiegung technisch nicht möglich. Weiterhin würde der Platzbedarf erhebliche Ausmaße annehmen.In the case of deT processing .different conveying means in the known two or more spindle screw pumps, it is often necessary to use the good for Purpose of intensive heating, cooling or other work-through, above all plastic masses to be left in the conveying chamber for a longer period of time.-An extension of the Working screws' many times over is usually not sufficient and on the other hand technically not possible because of the excessive deflection. Furthermore, the space requirement would take on considerable proportions.

Die Erfindung löst das Problem der längeren Durcharbeitszeit mit einer einfachen Konstruktion,-in :dem die eingreifenden Seitenschrauben durch rückführende Kanäle im Gehäuse der Hauptschraube nachgeschaltet sind. Die Erfindung bietet damit die Möglichkeit, das Fördergut so zu führen, daß durch mehrfache Umkehr und Ausbreitung alle kleinsten Teilchen des Fördergutes mehrfach mit den Schraubengängen und der Gehäusewand in Berührung kommen. Weiterhin ist es möglich, die Pumpe so auszubilden, daß das Fördergut vom Eintritt bis zum Austritt an allseitig beheizten öder gekühlten Wänden entlang gleitet.The invention solves the problem of longer working hours with a simple construction, -in: which the engaging side screws by returning Channels in the housing of the main screw are connected downstream. The invention thus offers the possibility of guiding the conveyed material in such a way that by repeated reversals and spreading all the smallest particles of the conveyed material several times with the screw threads and the Come into contact with the housing wall. It is also possible to design the pump in such a way that that the conveyed goods are cooled on all sides heated or cooled from entry to exit Slides along walls.

Die Erfindung ist an Hand einiger Ausführungsbeispiele näher veranschaulicht.The invention is illustrated in more detail using a few exemplary embodiments.

Abb. i zeigt einen Längsschnitt durch eine Kapselpumpe mit zwei Arbeitsschrauben, Abb. 2 den dazugehörigen Querschnitt; Abb.3 stellt eine Pumpe mit drei Arbeitsschrauben in senkrechter Bauart im Längsschnitt dar; Abb.4 zeigt den dazugehörigen Seitenriß ohne Außenzylinder und Abb. 5 den dazugehörigen Querschnitt.Fig. I shows a longitudinal section through a capsule pump with two working screws, Fig. 2 shows the associated cross-section; Fig.3 shows a pump with three working screws in vertical design in longitudinal section; Fig.4 shows the corresponding side elevation without outer cylinder and Fig. 5 the corresponding cross-section.

Wie aus Abb. i ersichtlich, wird das Fördergut im Trichterraum a des_ Pumpengehäuses r vom Fördergewinde der Hauptschraube 2 erfaßt und mit Hilfe der leer .mitlaufenden Seitenschraube 3, die vom Trichterraum abgeschlossen ist, in den Raum b am anderen Ende der Hauptschraube 2 gefördert. Der Raum bist voll der Seitenschraube 3 abgeschlossen. Durch die Rücklaufleitung 4 wird das Gut vom Raum b der Seitenschraube 3 (an der Trichterseite) wieder zugeführt. Mit Hilfe der Hauptschraube 2, die kraftschlüssig mitläuft, wird das 'Fördergut in der Gehäusebohrung der Seitenschraube 3 vortransportiert und an der Austrittsöffnung c des Gehäuses i ausgestoßen.As can be seen from Fig. I, the conveyed material in the hopper space a des_ Pump housing r detected by the delivery thread of the main screw 2 and with the help of empty. rotating side screw 3, which is closed from the funnel space, in promoted the space b at the other end of the main screw 2. The room is full of Side screw 3 completed. Through the return line 4, the material is removed from the room b fed back to the side screw 3 (on the funnel side). With the help of the main screw 2, which runs with a force fit, is the 'conveyed goods in the housing bore of the side screw 3 transported forward and ejected at the outlet opening c of the housing i.

Nach Abb. 3 wird die im Trichterraum d des Pumpengehäuses 5 angefallene Fördermasse von der Hauptschraube 6 erfaßt und mit Hilfe der beiden dicht kämmenden leeren Seitenschrauben 7 und 8, die an der oberen Stirnseite gegen den Trichterraum abgeschlossen sind, -in den Ringraum e des Gehäuses 5 gefördert. Die §eiten--schrauben 7 und 8 sind ebenfalls vom Ringraum abgeschlossen. Durch Austrittsbohrung und Rücklaüfnut f am Umfang des Pumpengehäuses 5, die, durch den umhüllenden Zylinder 9 begrenzt, einen Kanal bildet, wird das Fördergut der Seitenschraube 7 radial an der Trichterseite zugeführt und durch die mitlaufende Hauptschraube 6 nach unten gefördert. Durch eine Bohrung und Rücklaufnut g, die durch eine weitere Querbohrung mit der Seitenschraube-8 verbunden ist, wird das Gut erneut zurückgeführt. Durch die mitlaufende Hauptschraube 6 werden dann die Massen an der Austrittsbohrung la im Gehäuse 5 und Außenzylinder 9 ausgestoßen. Damit ist das Fördergut vierfach umgelenkt und verformt. Es ist natürlich möglich, durch eine Vielzahl von Seitenschrauben eine vielfaclieVerarbeitung und eine beliebig lange Verweilzeit zu erzielen.According to Fig. 3, the accumulated in the funnel space d of the pump housing 5 is Conveyed mass detected by the main screw 6 and with the help of the two tightly intermeshing empty side screws 7 and 8 on the upper face against the funnel space are completed -in the annular space e of the housing 5 promoted. The sides - screw 7 and 8 are also closed off by the annulus. Through outlet bore and return groove f on the circumference of the pump housing 5, which, limited by the enveloping cylinder 9, forms a channel, the conveyed material of the side screw 7 is radial on the funnel side fed and promoted by the main screw 6 moving downwards. By a hole and return groove g, which is through another cross hole with the side screw-8 is connected, the goods are returned again. With the main screw running along 6 then the masses at the outlet hole la in the housing 5 and outer cylinder 9 ejected. The conveyed material is thus deflected and deformed four times. It is natural possible, a variety of processing and processing by a large number of side screws to achieve an arbitrarily long dwell time.
