Description
Die Erfindung betrifft einen Mischer zum Mischen kontinuierlich fließender Flüssigkeiten oder einer Flüssigkeit mit einem Pulver gemäß dem Oberbegriff des Patentanspruchs.The invention relates to a mixer for mixing continuously flowing liquids or a liquid with a powder according to the preamble of the claim.
Ein derartiger Mischer ist aus der CA-PS 6 77 401 bekannt, wobei die konstruktive Gestaltung speziell auf den Anwendungszweck, d. h. die Herstellung von Polyvinylalkohol abgestellt ist. Hierbei wird eine nicht viskose Flüssigkeit mit einer viskosen Flüssigkeit gemischt, wobei ein kontinuierlicher Film gebildet wird. Eine rotierende Verteilvorrichtung teilt den Film in einzelne Tropfen, die auf einen gebildeten Film auftreffen. Die Flüssigkeit überläuft den Überlauf, ohne daß eine Verwirbelung auftritt, so daß die Mischung allenfalls für die speziellen Flüssigkeiten ausreichend ist.Such a mixer is known from CA-PS 6 77 401, the structural design being specific the purpose of use, d. H. the production of polyvinyl alcohol has been stopped. This becomes a non-viscous one Liquid mixed with a viscous liquid to form a continuous film. A rotating one Distribution device divides the film into individual drops that hit a formed film. the Liquid overflows the overflow without turbulence occurring, so that the mixture is at best for the special liquids is sufficient.
Bisher war es aber außerordentlich schwer. Pulver in Flüssigkeiten aufzulösen bzw. zu mischen infolge des Auftretens von Pulverklumpen und Schwierigkeiten in der Durchflußmenge bzw. dem Durchfluß usw. ohne Rücksicht auf Ansatz und Mischertyp, so daß es unmöglich war, eine einstufige Auflösung mit optimalen Bedingungen aufrechtzuerhalten.So far it has been extremely difficult. Powder in Dissolve or mix liquids due to the appearance of powder lumps and difficulties in the flow rate or the flow rate etc. regardless of approach and mixer type, so that it is impossible was to maintain a one-step dissolution with optimal conditions.
Zur Mischung von festen Materialien mit Flüssigkeiten ist ein Mischer der eingangs genannten Art aus der BE-PS 7 46 374 bekannt. Bei diesem Mischer befindet sich der Überlaufkonus für die Flüssigkeit unterhalb eines Zugabetrichters mit einem Verteiler für das zu vermischende feste Gut. Der rotierende Verteiler wirft das feste Gut auf die Oberfläche der in dem Überlaufkonus befindlichen Flüssigkeit, so daß die Vermischung dort erfolgt. Durch diese Art der Aufbringung ist eine einwandfreie Mischung insbesondere aber Lösung bzw. Reaktion nicht gewährleistet, da die Mengenverhältnisse schlecht aufeinander abzustimmen sind und andererseits die Berührungszeit durch die Nähe des Überlaufs verhältnismäßig kurz ist A mixer of the type mentioned at the beginning is known from BE-PS 7 46 374 for mixing solid materials with liquids. In this mixer, the overflow cone for the liquid is located below an addition funnel with a distributor for the solid material to be mixed. The rotating distributor throws the solid material onto the surface of the liquid in the overflow cone, so that mixing takes place there. This type of application does not guarantee perfect mixing, in particular solution or reaction, since the proportions are difficult to match and, on the other hand, the contact time is relatively short due to the proximity of the overflow
s Einstufige Vermischungen sind auch mit den üblichen Niischern, bei denen unterhalb eines Mischtanks oder -trichtere ein rotierender Mischtisch vorgesehen ht (US-PS 26 41 453 und DE-PS 9 27 685) optimal nicht zu erreichen, zumal auch hier der Nachteil besteht, daß dass One-stage mixes are also possible with the usual Niischern, with those below a mixing tank or -trichtere a rotating mixing table provided (US-PS 26 41 453 and DE-PS 9 27 685) optimally not too achieve, especially since there is also the disadvantage that the
ίο tatsächliche Mischungsverhältnis nicht immer bei einstufiger Mischung den Sollanforderungen entsprichtίο the actual mixing ratio does not always correspond to the target requirements in the case of single-stage mixing
Die Aufgabe der Erfindung besteht daher darin, einen Mischer zu schaffen, in dem die Auflösung bzw. Mischung von Pulver und Flüssigkeit oder FlüssigkeitenThe object of the invention is therefore to provide a To create mixer in which the dissolution or mixture of powder and liquid or liquids kontinuierlich durchgeführt werden kann.can be carried out continuously.
Gelöst wird diese Aufgabe durch die im Anspruch angegebenen Merkmale. Erreichbar sind dadurch die folgenden Vorteile: This problem is solved by the features specified in the claim. The following advantages can be achieved in this way:
1. zur selben Zeit mit der Inbetriebnahme fließt eine gleichmäßige Lösung kontinuierlich in konstanter Durchflußmenge ohne zwischengeschaltete Einrichtungen aus, 1. at the same time as the start-up, a uniform solution flows out continuously at a constant flow rate without any intermediate devices,
2. Strahlmischung und Auflösung finden während des kontinuierlichen Herabfließens der Flüssigkeit statt, ohne daß Unterschiede in der Durchflußmenge und dem Durchfluß bestehen und die Mischung, Lösung und Reaktion erfolgt extrem schnell durch die Filmbildung der Flüssigkeit in dem Überlaufkonus. 2. Jet mixing and dissolution take place during the continuous downward flow of the liquid instead of without differences in the flow rate and the flow and the mixture, Solution and reaction take place extremely quickly due to the film formation of the liquid in the overflow cone.
Die Erfindung soll nun anhand der Zeichnung, die eine Ausführungsform darstellt, erläutert werden.The invention will now be explained with reference to the drawing, which shows an embodiment.
