Description

Es sind bereits Knetpumpen bekanntgeworden, ihtllicil Schraubenpunpen, bei welchen das Fördergut von der Hauptspindel mit abnehmendem Gangvolumen durch die Gewindeflanken in die NebensI'indel mit zunehmendem Gangvolumen gepreßt wurde (s. Patentschrift 682 787). Kneading pumps have already become known, ihtllicil screw pumps, in which the material to be conveyed by the main spindle with decreasing aisle volume the thread flanks were pressed into the secondary spindle with increasing thread volume (see patent 682,787).

Da es praktisch nicht möglich ist, das Gangvoiurnen bis auf den Wert Null zu verringern, so ergab sich bei diesen Knetpumpen der Nachteil einer stoßweisen Förderung. Außerdem erwiesen sich die zahntechnisch notwendigen Flankenspiele für manche Fälle als zu groß. Since it is not practically possible, the gang voiurnen up to the value To reduce zero, these kneading pumps had the disadvantage of being intermittent Advancement. In addition, the backlash that is necessary for dental technology has proven to be some cases as too big.

Beide Nachteile werden durch vorliegende Erfindung beseitigt. Hiernach wird das Fördergut zunächst durch eine Pumpe bekannter Bauart, z. B. eine Schraubenpumpe, auf Druck gebracht und wird dann von abgeschlossenen Druckraum einer l-lau;>tspindel mit planparallelen Kämmen in den Raum einer mit ihr kämmenden Nebenspindel gedrückt. Damit ergibt sich eine vollkommen gleichmäßige Förderung durch beliebig enge Spalte und außerdem werden evtl. im Fördergut vorhandene körnige Bestandteile zermahlen. Both disadvantages are eliminated by the present invention. After that the material to be conveyed is first carried out by a pump of a known type, e.g. B. a screw pump, brought to pressure and is then from the closed pressure chamber of a lau;> tspindel pressed with plane-parallel combs into the space of an auxiliary spindle that meshes with it. This results in a completely uniform conveyance through any narrow gap and in addition, any granular components that may be present in the conveyed material are ground up.

In Fig. I ist ein Längsschnitt durch die Feinknetpumpe und in Fig. 2 ein Querschnitt durch diese dargestellt. Das Fördergut tritt in den Saugraum a ein und wird von der Hauptspindel b und der Nebenspindel c der Schraubenpumpe in den abgeschlossenen Druckraum d der Hauptspindel e der Feinknetpumpe gefördert. Von hier aus wird es durch die axialen und radialen Spalte der Gewindekämme in den Raum f der Nebenspindel g gefördert, von wo es ins Freie tritt oder unter Druck weitergeführt wird. In Fig. I is a longitudinal section through the fine kneading pump and in Fig. 2 shows a cross section through this. The conveyed material enters the suction chamber a a and is driven by the main spindle b and the sub spindle c of the screw pump in promoted the closed pressure chamber d of the main spindle e of the fine kneading pump. From here it is through the axial and radial gaps of the thread crests into the Space f of the secondary spindle g promoted, from where it emerges into the open or under pressure is continued.

Durch eineAusgleichleitungh können die Spindeln mit Hilfe des Fördergutes vom -Äxialschul) entlastet werden. The spindles can be adjusted with the aid of the conveyed material through an equalization line from the -Äxialschul) are relieved.

Durch ein Regelorgan i vor der Feinknetpumpe mit Rücklauf zum Saugraum kann der Druck vor derselben und damit die Fördermenge geändert werden. Ferner wird damit eine Vormischung des Fördergutes erreicht. By a control element i in front of the fine kneading pump with return to the suction chamber the pressure before the same and thus the flow rate can be changed. Furthermore, so that a premixing of the conveyed material is achieved.

Durch ein- oder beidseitig angebrachte Stellstiicke k kann der Radialspalt und damit Qualität und Fördermenge verändert werden. The radial gap can be opened by adjusting pieces k attached on one or both sides and thus quality and delivery rate are changed.

Durch eine schwach konische Ausfiihrung der 1 ndkämme 1, m, der Knetpumpe oder sämtlicher Kämme kann ein gegenseitiger Axialschub zwischen den Spindeln aufgenommen werden. Through a slightly conical design of the 1 nd combs 1, m, of the kneading pump or a mutual axial thrust between the spindles can be absorbed by all of the combs will.

PATENTANSPROCE: 1. Feinknetpumpe, gekennzeichnet durch zwei oder mehrere planparallel dicht ineinander kämmende Spindeln (e, g), die in getrennten Räumen (d,f) laufen und nur durch ihre axialen und radialenSpalte in Verbindung stehen, durch welche mit Hilfe einer Pumpe, z. B. einer Schraubenpumpe (h, c). das zu knetende Fördergut gepreßt wird. PATENTANSPROCE: 1. Fine kneading pump, identified by two or several spindles (e, g) meshing closely with one another plane-parallel and in separate Spaces (d, f) run and only communicate through their axial and radial gaps stand through which with the help of a pump, e.g. B. a screw pump (h, c). the to be kneaded conveyed is pressed.
