Description

Knetpumpe Es ist schon bei Knetpumpen vorgeschlagen worden, was aber nicht zum Stande der Technik gehört, das zu behandelnde Gut unter gleichzeitigem Fortpumpen gegen hohe Drücke durch besondere Eingriffsverhältnisse von Schnecken in einem dichtschließenden Gehäuse durchzukneten. Bei diesen Vorrichtungen sind die beiden Schnecken in gleicher Weise ausgebildet, und zwar so, daß die Gewindegänge stark divergent mit gleichbleibender Steigung jeder Wendelfiäche geschnitten sind und daß am Ende die Schnekken miteinander kaspelpumpenartigen Eingriff zeigen.Kneading pump It has already been suggested for kneading pumps, but what does not belong to the state of the art, the goods to be treated under the same time Pumping against high pressures due to the special meshing conditions of screws Knead in a tightly fitting housing. These devices are the two screws formed in the same way, in such a way that the threads are cut strongly divergent with a constant slope of each spiral surface and that at the end the screws show a cartridge pump-like engagement with one another.

Unter Verwendung von so ausgebildeten Schnecken, die aber erfindungsgemäß in grundsätzlich neuer Weise zusammenarbeiten, nämlich derart, daß das Gut von den Gängen einer Hauptspindel durch dichtschließende Flankenspalten in einen oder mehrere Gänge einer Nebenspindel übergepreßt wird, wurde eine neue Knetpumpe ausgebildet, die den Vorzug hat, zwangsläufig alle Teile des handlungsgutes durch fortlaufende enge Flankenspalten hindurchzupressen und hindurchzuscheren. Die-Knetpumpe nach vorliegender Erfindung besteht aus mehreren teils rechts- und teils linksgängigen Schnekken, die breitgängig mit zusammenlaufenden Wendelflächen gleichbleibender Steigung geschnitten sind und schraubenpumpenförmigen Eingriff besitzen, wobei die Hauptspindel vom Eintritts- zum Austrittsende abnehmendes, die damit dichtkämmende Nebenspindel vom Eintritts- zum Austrittsende entsprechend zunehmendes Gangvolumen besitzt. Using screws designed in this way, but according to the invention to work together in a fundamentally new way, namely in such a way that the goods of the Threads of a main spindle through tightly closing flank gaps in one or more Gears of a secondary spindle are pressed over, a new kneading pump was designed, which has the preference, inevitably, all parts of the merchandise through continuous to press through narrow gaps in the flank and shear through. Die-kneading pump after The present invention consists of several partly right-handed and partly left-handed Snails, which are more consistent with wide-threading with converging helical surfaces Pitch are cut and have screw pump-shaped engagement, the Main spindle decreasing from the inlet to the outlet end, the one that meshes closely with it Secondary spindle from entry to exit end correspondingly increasing passage volume owns.

Selbstverständlich können statt einer Hauptspindel oder einer Nebenspindel auch jeweils deren mehrere vorhanden sein, ohne daß sich dadurch in der Wirkungsweise der Schnecken etwas ändert.Of course, instead of a main spindle or an auxiliary spindle several of them may also be present without affecting the mode of operation the snail changes something.

Abb. 1 zeigt eine Knetpumpe mit einer Haupt- und einer Nebenspindel im Längsschnitt, Abb. 2 und 3 im Querschnitt. Fig. 1 shows a kneading pump with a main and a secondary spindle in longitudinal section, Fig. 2 and 3 in cross section.

Die Hauptspindel a und die Nebenspindel b sind drehbar im Gehäuse c gelagert, das die Schraubenspindeln umhüllt. The main spindle a and the secondary spindle b are rotatable in the housing c stored, which envelops the screw spindles.

Wie ersichtlich, nehmen von links nach rechts die Nutbreiten d des Gewindes der Hauptspindel ab, während sie bei der Nebenspindel zunehmen. Das Fördermittel gelangt bei A in die Gewindenuten der Hauptspindel, da die erste Nut am Eintritt frei ist. In die Gewindenuten der Nebenspindel kann am Eintritt kein Fördermittel gelangen, weil die Gewindenuten dieser Spindel vom Gehäuse umschlossen sind und weil außerdem die Nut an der Stirnseite z. B. durch eine Platte g abgeschlossen ist. Aus den Gewindenuten der Hauptspindel kann kein, Fördermittel zum Austritt D gelangen, weil die Nuten durch das Gehäuse am Umfang und an der Stirnseite abgeschlossen sind. As can be seen, the groove widths d des take from left to right Thread of the main spindle, while they increase in the secondary spindle. The funding at A enters the thread grooves of the main spindle because the first groove is at the entrance free is. No conveying means can enter the thread grooves of the secondary spindle get because the thread grooves of this spindle are enclosed by the housing and because also the groove on the front side z. B. completed by a plate g is. No funding can come from the thread grooves of the main spindle to the Exit D get because the grooves through the housing on the circumference and on the face Are completed.

Das ganze Fördermittel, das bei A in die Gewindenuten der Hauptspindel eintritt, wird bei der Drehung der beiden Spindeln nach der Austrittsseite befördert. Da die Gewindenuten dabei immer enger werden, twird das Fördermittel unter Druck durch die Flankenspalte s-s in die Gewindenuten der Nebenspindel und von hier aus zum Austritt gefördert. Um die Flankenspaltes-s von einem Kleinstwert beliebig während des Betriebes vergrößern zu können, wodurch der Druck in den Nuten der Hauptspindel beliebig herabgesetzt werden kann, wird die Nebenspindel durch die Stellmutter h nach links verschoben. Am Austritt D kann noch eine Lochplattei oder ein Regelventil angebracht werden, wodurch vor dem Austritt das Fördergut zusätzlich auf Druck gebracht und nochmals geknetet wird. All of the conveyance that goes into the thread grooves of the main spindle at A enters, is conveyed to the exit side when the two spindles rotate. Since the thread grooves are getting narrower and tighter, the conveying means is under pressure through the flank gap s-s into the thread grooves of the secondary spindle and from here funded to leave. Around the flank gap -s from a minimum value arbitrarily during of operation to increase the pressure in the grooves of the main spindle can be reduced as desired, the secondary spindle is adjusted by the adjusting nut h shifted to the left. A perforated plate or a control valve can also be installed at outlet D. be attached, whereby the conveyed material is additionally put under pressure before exiting and knead again.

Die in der vorliegenden Erfindung beanspruchte Vorrichtung soll zur Bearbeitung knetbarer Massen, z. B. in der keramischen und Kautschukindustrie, verwendet werden. The device claimed in the present invention is intended to Processing of kneadable masses, e.g. B. used in the ceramic and rubber industries will.
