Description

Beschickungsvorrichtung für Löse-, Emulgier- und Rührvorrichtungen In der chemischen Industrie und in den verwandten Industrien werden in großem Umfauge Lösungen, Emulsionen und Suspensionen mittels rasch laufender Zerteilungsmaschinen mit oder ohne Aufnahmebebälter hergestellt.Loading device for dissolving, emulsifying and stirring devices In the chemical industry and in allied industries are used extensively Solutions, emulsions and suspensions by means of rapidly running dividing machines manufactured with or without receptacle.

Diese Maschinen bestehen aus konischen oder ebenen Reibkörpern, die so angeordnet sind, daß zwischen ihnen sehr enge Spalte entstehen, oder sie sind als Schleudervorrichtungen ausgebildet, in denen Schleuderscheiben mit kreisringförmig angeordneten Zähnen oder unterbrochenlen Flügeln sich mit geringem radialem Spiel an stillstehtenden Gegenzähnen oder Flügeln vorbeibewegen, so daß die zu behandelnde Flüssigkeit ständig in einzelne Flüssigkeitsfäden zerteilt wird.These machines consist of conical or flat friction bodies that are arranged so that very narrow gaps arise between them, or they are designed as centrifugal devices, in which centrifugal discs with circular ring arranged teeth or interrupted wings with little radial play move past stationary opposing teeth or wings so that the to be treated Liquid is constantly broken up into individual threads of liquid.

Auch sind Mischvorrichtungen bekannt, die mit Zahnradp. umpen über Aufnahmebehälter im Kreislauf arbeiten. Die Beschickung der Maschinen vorgenannter Arten macht keine Schwierigkeiten, solange es sich um das Mischen von Flüssigkeiten oder solchen handelt, in denen fein verteilte, pulverförmige Stoffe zugesetzt werden. Diese treten jedoch sofort auf, wenn Flüssigkeiten mit plastischen gelatineartigen Körpern gemischt werden sollen. Die vorliegende Erfindung betrifft eine Vorrichtung, mit welcher derartige plastische Massen in den genannten Maschinen verarbeitet werden können. Mixing devices are also known, which with Zahnradp. umpen over Work receptacle in a cycle. The loading of the machines mentioned above Species makes no problem as long as it involves mixing liquids or those in which finely divided, powdery substances are added. However, these occur immediately when liquids containing plastic gelatinous Bodies to be mixed. The present invention relates to a device with which such plastic masses are processed in the machines mentioned can.

Die Vorrichtung besteht aus einer an sich bekannten langsam laufenden Zahnradpumpe a mit einem darüber befestigten Aufgabetrichter b. Mit dieser Vorrichtung ist vorerst der gewünschte Effekt'nicht zu erzielen, da die plastischen Massen in dem Trichter hängenbleiben ;und- von den Zahnrädern c c der Zahnradpumple a nicht erfaßt und gefördert werden können. The device consists of a known slow-running Gear pump a with a hopper attached above it b. With this device the desired effect cannot be achieved for the time being because the plastic masses in get stuck in the funnel; and- of the gears c c of the gear pump a not can be recorded and promoted.

Auch die einmalige Füllung der Zahnradpumpela mit Flüssigkeit oder auch mit der plastischen Masse selbst bringt keine Abhilfe, da zwischen den einzelnen aufggebenen Masseteilen wieder Luft hindurch treten kann, die ein Ansaugen der Masse selbst verhindert. Erfindungsgemäß wird nun der Aufgabetrichter b mit einem Kragen versehen, der einen Hohlraum e zwischen sich und dem Trichter frei läßt. Die Mischmaschine f selbst wird nun zunächst mit der dünnflüssigen Komponente, z. B. Wasser, gefüllt und in Tatigkeit gesetzt. Durch die Rohrleitung g wird nun ein Teil dieser Komponente in den Hohlraum e abgeführt und bildet in dem Trichter b einen Flüssigkeitsschleier k, der das Anhängen der plastischen Masse an der TriNterwandung verhütet, indem er die aufgegebenen Stücke den Zahnrädern c zuspült. Durch diese Maßnahme werden die Zahnlücken der Zahnradpumpe a dauernd mit Flüssigkeit gefüllt und die Pumpe abgedichtet, so daß sie in der Lage ist, eine kräftige Saugwirkung auf solche Masseteile auszuäben, die sich in der Saugöffnung i der Pumpe festsetzen. Diese Saugwirkung würde nicht genügen, um Brokt ken, die unregelmäßig geformt und größer sind als die Saugöffnung i, in die Pumpe@ hineinzuziehen, wenn nicht bei Verstopfung der Öffnung 1 die in den Trichter geförderte Flüssigkeit über diesen Brocken aufstauen und eine hermetische Abdichtung bewirken würde. Also the one-time filling of the gear pump with liquid or even with the plastic mass itself does not bring any remedy, since between the individual abandoned parts of the mass air can pass through, which causes a suction of the mass prevented himself. According to the invention, the feed hopper b is now provided with a collar provided, which leaves a cavity e between itself and the funnel. The mixer f itself is now first with the thin component, z. B. water filled and put into action. Part of this component is now through the pipeline g discharged into the cavity e and forms a liquid curtain in the funnel b k, which prevents the plastic mass from sticking to the triangle wall by he flushes the abandoned pieces to the gears c. Through this measure will be the gaps between the teeth of the gear pump a are permanently filled with liquid and the pump is sealed so that it is able to generate a powerful suction ausäben those mass parts that get stuck in the suction opening i of the pump. This suction would not be sufficient to remove broken pieces that are irregularly shaped and are larger than the suction opening i, to be drawn into the pump @, if not at Blockage of opening 1, the liquid conveyed into the funnel via this Damming up chunks and creating a hermetic seal.

Hierdurch ist es möglich, einzelne Brocken in die Pumpe mit Sicherheit hineinzuziehen, deren Querschnitt wesentlich größer als der der Saugöffnung i ist. Die von der Pumpe geförderte plastische Masse wird dann durch eine Rohrleitung k dem Mischer J zugeführt, und zwar zweckmäßig durch eine oder mchrere Öffnungen l, wo sie in Strangform austritt und durch die vorbeilaufenden Zähne in des Mischers in kleine Teile zerrissen und hierdurch vorzerkleinert wird. Die weitere Lölsung oder Emulgierung erfolgt an sich in bekannter Weise. Es ist natürlich auch mög@ lich, -den Ringraum e aus einer fremden Flüssigkeitsquelle durch das Absperrorgan fl zu speisen.This makes it possible to get individual chunks into the pump with certainty pull in, the cross-section of which is significantly larger than that of the suction opening i. The plastic mass delivered by the pump is then passed through a pipe k fed to the mixer J, expediently through one or more openings l, where it emerges in strand form and through the passing teeth into the mixer is torn into small pieces and thereby pre-shredded. The further solution or emulsification takes place in a known manner. It is of course also possible @ Lich, -the annulus e from a foreign source of liquid through the shut-off device fl to dine.

In der Praxis hat sich ergeben, daß in dem als Kegel ausgebildeten Trichter b die - Flüssigkeitsschicht h in starke Rotation gerät. In practice it has been found that in the designed as a cone Funnel b the - liquid layer h is in strong rotation.

Hierdurch bildet sich ein Strudel, durch den Luft in die Pumpe eingesaugt wird. Um dies zu vermeiden, wird der Aufgabetrichter zweckmäßig mit unrundem Querschnitt ausgeführt. This creates a vortex through which air is sucked into the pump will. In order to avoid this, the feed hopper is expediently provided with a non-circular cross-section executed.

Die Vorrichtung kann auch zur zusammenarbeit mit beliebigen anderen Mischmasschinen als der auf der Zeichnung dargestellten verwendet werden. The device can also work with any other Mixing machines other than the one shown in the drawing can be used.
