Abstract

The device comprises a tube (1) with a housing (2) arranged thereon and consisting of housing parts (8a, 8b), a bore (3) for the feeding of the liquid, a bore (4) for monitoring leak-tightness, an interior wall section (5) with recesses (6) for packing rings (28, 29), and a shoulder (7). A shaft (9) consists of lower and upper shaft sections (10, 12), the lower shaft section (10) possessing a longitudinal bore (11) with a first transverse bore (13) provided in a recess (13a) and a second transverse bore (14) in a nozzle head (15), in which nozzle head a nozzle device (16) is provided with a perforated nozzle (17). The upper shaft section (12) is mounted in ball bearings (19, 20) which are held at a distance by a sleeve (21). The ball bearing (19) is held in position by the shoulder (7) and a shaft extension (18), and the ball bearing (20) is held in position by a first retaining ring (23), which can be inserted into a first annular groove (22), and by a second retaining ring (25) which can be fitted into a second annular groove (24). An elongate groove (27) is provided at the shaft end (26). <IMAGE>

Description

Es sind Mischvorrichtungen bekannt, bei denen in einer Rohrleitung fließenden Flüssigkeiten über ein System von mehreren Lochdüsen eine andere Flüssigkeit (beispielsweise Farbstoff) zugemischt wird.Mixing devices are known in which liquids flowing in a pipeline a system of several perforated nozzles other liquid (e.g. dye) is admixed.

Speziell bei hochviskosen Flüssig­ keiten besteht die Möglichkeit, daß eine oder mehrere Düsen verstopfen und dadurch die Mischqualität beeinträchtigt wird, selbst wenn durch eine Dosierpumpe die gleiche Flüssigkeitsmenge durch die noch offenen Düsen zugemischt wird.Especially for highly viscous liquids There is a possibility that an or several nozzles clog and thereby the mixing quality is affected, even if by a Dosing pump the same amount of liquid is mixed in through the still open nozzles.

Die vorliegende Erfindung vermeidet diesen Nachteil dadurch, daß nur eine Düse verwendet wird, die in der Rohrleitung rotiert und dadurch die zugemischte Flüssigkeit gleichmäßig verteilt. Eine Verstopfungsgefahr ist praktisch nicht mehr gegeben, da dann der Druck der Dosierpumpe so hoch steigt, bis die Düse wieder frei wird.The present invention avoids this Disadvantage in that only one nozzle is used that rotates in the pipeline and thereby the mixed liquid evenly distributed. There is practically no longer any risk of constipation given, because then the pressure of the metering pump rises until the nozzle is free again.

Fig. 1 zeigt eine Ausführung dieser Erfindung. Durch die Rohrleitung 1 fließt die Hauptflüssigkeit. Die zugemischte Flüssigkeit wird durch die Bohrung 2 im Gehäuse 3 zugeführt und fließt von dort über die Bohrung 4 in der Welle 5 durch die in dem Düsenkopf 6 angebrachte Lochdüse 7. Die Welle 5 ist im Gehäuse 3 durch die Lager 8 und 9 drehbar gelagert und wird über das Wellenende 10 von einem Motor angetrieben. Zwischen den beiden Dichtungen 11 und 12 auf der Welle 5 befindet sich eine Öffnung 13, sie dient zur Kontrolle der Dichtigkeit und kann auch als Zufuhr von Schmiermitteln für die Dichtungen benutzt werden. Fig. 1 shows an embodiment of this invention. The main liquid flows through the pipeline 1 . The admixed liquid is supplied through the bore 2 in the housing 3 and flows from there through the bore 4 in the shaft 5 through the perforated nozzle 7 arranged in the nozzle head 6 . The shaft 5 is rotatably supported in the housing 3 by the bearings 8 and 9 and is driven by a motor via the shaft end 10 . Between the two seals 11 and 12 on the shaft 5 there is an opening 13 , which serves to check the tightness and can also be used as a supply of lubricants for the seals.

Fig. 2 zeigt eine Ausführung der Erfindung, bei der anstelle der Lochdüse 7 ein Düsenventil 17 angeordnet ist. Eine Feder 18 drückt das Düsenventil 17 bei abgestellter Fördermenge auf den Ventilsitz 19 und verhindert gleichzeitig, daß die Hauptflüssigkeit in die Bohrung 4 der Welle 5 gelangen kann. Je stärker die Kraft der Feder 18 ist, um so größer muß der Druck der zugemischten Flüssigkeit sein und um so besser ist die Verteilung der zugemischten Flüssigkeit in der Hauptflüssigkeit. FIG. 2 shows an embodiment of the invention in which a nozzle valve 17 is arranged instead of the perforated nozzle 7 . A spring 18 presses the nozzle valve 17 on the valve seat 19 when the delivery quantity is stopped and at the same time prevents the main liquid from getting into the bore 4 of the shaft 5 . The stronger the force of the spring 18 , the greater the pressure of the mixed liquid must be and the better the distribution of the mixed liquid in the main liquid.
