Description

Die Erfindung betrifft eine Mischvorrichtung zum gleichmäßigen Verteilen eines fließfähigen Mischgutes in einem durch eine Mischkammer fließenden Strömungsmittel, in welchem stehende Wellen erzeugt werden. The invention relates to a mixing device for uniform distribution a flowable material to be mixed in a fluid flowing through a mixing chamber, in which standing waves are generated.

Es ist eine Einrichtung zur mechanischen Schwingungsbehandlung eines Gutes mit Schall- oder Ultraschallstrahlen bekannt, die zwei Schwingkörper aufweist, von denen einer mit einer Mikrometerschraube verstellt werden kann, um in dem Behandlungsraum stehende Wellen zu erzeugen. Bei dieser Einrichtung ist es erforderlich, die Schwingungsenergie dem Behandlungsgut über elektro-akustische Wandler zuzuführen. It is a device for mechanical vibration treatment of a Good known with sonic or ultrasonic beams, which has two oscillating bodies, one of which can be adjusted with a micrometer screw to put in the treatment room to generate standing waves. With this device it is necessary to reduce the vibration energy to be fed to the material to be treated via electro-acoustic transducers.

Es ist weiter bekannt, daß beim Durchleiten von mit Wasserdampf und Kohlenstaub vermischter Luft durch eine 4,5 mm weite Glasröhre bei einem Druck von 600 Torr Hochfrequenzschwingungen der Luftsäule an dem Auftreten periodischer Kohlenstaubringe beobachtet werden. Bei dieser Anordnung wird demnach ein Unterdruck zum Durchführen des Gemisches durch die Glasröhre angelegt. It is also known that when passing through with steam and Coal dust of mixed air through a 4.5 mm wide glass tube at a pressure of 600 Torr high frequency vibrations of the air column on the appearance of periodic coal dust rings to be observed. With this arrangement, therefore, a negative pressure is required to perform of the mixture applied through the glass tube.

Die Erfindung bezweckt eine Mischvorrichtung, mit der ein Mischgut in einem Strömungsmittel homogen und in feiner Dispersion verteilt werden kann. Mit bekannten Vorrichtungen für diesen Zweck lassen sich entweder nur ungenügend feine Dispersionen herstellen, oder der Durchsatz ist beschränkt. The invention aims at a mixing device with which a material to be mixed can be distributed homogeneously and in fine dispersion in a fluid. With known devices for this purpose can either only inadequate produce fine dispersions or throughput is limited.

Die Erfindung bezweckt deshalb eine Mischvorrichtung mit einer Druckquelle, die keine beweglichen Teile aufweist und mit hohem Wirkungsgrad eine homogene Dispersion eines Mischgutes in einem Strömungsmittel bewirken kann. The invention therefore aims at a mixing device with a pressure source, which has no moving parts and a homogeneous dispersion with high efficiency a mixture in a fluid can cause.

Bei einer Mischvorrichtung nach der Erfindung ist der Durchmesser der Mischkammer größer als der Durchmesser der in diese zentral einmündenden Einlaßleitung für das unter Druck stehende Strömungsmittel, die zur Einlaßleitung koaxiale Auslaßleitung endigt scharfkantig in der gegenüber der Mündung der Einlaßleitung angeordneten verstellbaren Stirnwand der Mischkammer, und eine Ansaugleitung für das Mischgut mündet nahe der Mündungsstelle der Einlaßleitung in die Mischkammer in einem spitzen Winkel zur Achse derselben konvergierend. In a mixing device according to the invention, the diameter is the mixing chamber is larger than the diameter of the inlet line opening into it centrally for the pressurized fluid, the outlet line coaxial with the inlet line ends with sharp edges in the opposite of the mouth of the inlet line arranged adjustable end wall of the mixing chamber, and a suction line for the mix opens near the point of opening of the inlet line in the mixing chamber in a pointed Angle converging to the axis thereof.

Hierdurch lassen sich durch Verstellen der auslaßseitigen Stirnwand der Mischkammer stehende Wellen in dem die Mischkammer durchsetzenden Strömungsmittel erhalten. Die Mischkammer bildet eine Erweiterung der das Strömungsmittel unter Druck durchsetzenden Leitung und daher eine Unterdruckquelle, die das Mischgut durch eine Ansaugleitung einsaugt, wobei das Mischgut in dem Strömungsmittel unter den beschriebenen Voraussetzungen homogen und fein dispergiert wird. Es wird angenommen, daß die stehenden Wellen in dem Strömungsmittel in der Mischkammer durch Reflexion an der auslaßseitigen Stirnwand erreicht werden, wobei festgestellt wurde, daß die scharfkantige Einmündung des Auslasses in diese Stirnwand von Bedeutung ist. Die in die Mischkammer konvergierend aufeinander zu eingeleiteten Strömungen aus dem Strömungsmittel und dem Mischgut durchqueren die durch die stehenden Wellen erzeugten Verdichtungs-und Verdünnungsräume und werden dabei völlig gemischt, so daß eine homogene Dispersion das auslaßseitige Ende der Mischkammer erreicht. In this way, by adjusting the end wall on the outlet side the mixing chamber standing waves in the fluid passing through the mixing chamber obtain. The mixing chamber forms an extension of the fluid below Pressure penetrating line and therefore a source of negative pressure that the mix through sucked in a suction line, wherein the mix in the fluid under the described requirements is homogeneously and finely dispersed. It is believed, that the standing waves in the fluid in the mixing chamber are by reflection be reached at the outlet end wall, it was found that the sharp-edged confluence of the outlet in this end wall is important. the into the mixing chamber converging towards one another to introduced currents from the Fluid and the mix traverse the generated by the standing waves Compression and dilution spaces and are completely mixed, so that one homogeneous dispersion reaches the outlet end of the mixing chamber.

An Hand der Figur wird die Erfindung beispielsweise erläutert. The invention is explained by way of example with the aid of the figure.

Die Figur zeigt einen Schnitt durch eine Mischkammer mit einer verstellbaren ebenen Stirnfläche nach der Erfindung. The figure shows a section through a mixing chamber with an adjustable one flat end face according to the invention.

Die Vorrichtung nach der Erfindung weist eine Mischkammer 1 auf, die eine Bohrung in einem Block 2 sein kann. Die Einlaßleitung 3 mündet in der Einlaßfläche 4 in die Mischkammer 1. Diese Einlaßfläche kann, wie in der Figur dargestellt, konisch oder eben sein. The device according to the invention has a mixing chamber 1, which can be a hole in a block 2. The inlet line 3 opens into the inlet surface 4 into the mixing chamber 1. This inlet surface can, as shown in the figure, be conical or just be.

Die Auslaßleitung 6 endigt in der Kammer 10 gegenüber der Einlaßleitung 3 und ist koaxial zu dieser angeordnet. Die Auslaßleitung6 bildet mit der Stirnfläche 7 der Mischkammer einen scharfen Rand. Der Durchmesser der Auslaßleitung 6 ist größer als der Durchmesser der Einlaßleitung 3. The outlet line 6 ends in the chamber 10 opposite the inlet line 3 and is arranged coaxially to this. The outlet conduit 6 forms with the end face 7 of the mixing chamber has a sharp edge. The diameter of the outlet pipe 6 is larger than the diameter of the inlet pipe 3.

Eine Ansaugleitung oder Zuleitung 5 mündet in die Mischkammer 1 neben der Mündung der Einlaßleitung 3 in dieselbe. Die Achse der Ansaugleitung 5 schneidet die Achse der Einlaßleitung 3 und der Mischkammer 1 in einem spitzen Winkel, so daß das Strömungsmittel und das Mischgut in konvergierenden Strömen zusammengeführt werden.A suction line or supply line 5 opens into the mixing chamber 1 next to it the mouth of the inlet line 3 in the same. The axis of the suction line 5 intersects the axis of the inlet line 3 and the mixing chamber 1 at an acute angle, so that the fluid and the mix are brought together in converging streams will.

Die axiale Länge der Mischkammer kann dadurch eingestellt werden, daß die Auslaßleitung sich in einem Stopfen 9 befindet, der verstellbar angeordnet ist. Der Stopfen 9 wird im Betrieb durch Drehen so lange verstellt, bis sich stehende Wellen in der Mischkammer ausbilden. Durch das Verändern der Einstellung des Stopfens 9 wird ein maximaler Unterdruck in der Ansaugleitung 5 erzeugt. Es wurde gefunden, daß dieser maximale Unterdruck von der Erzeugung stehender Wellen in der Mischkammer 1 abhängt, die einzig und allein durch den Strömungsmittelstrom durch die Druckeinlaßleitung 3, die Mischkammer 1 und die Auslaßleitung 6 bewirkt wird. Die Frequenz der stehenden Wellen in der Mischkammer 1 kann in derselben Art wie eine Posaune durch Bewegung ihres Schiebers eingestellt werden. The axial length of the mixing chamber can be adjusted by that the outlet line is located in a plug 9 which is arranged to be adjustable is. The stopper 9 is adjusted during operation by turning until it stops Form waves in the mixing chamber. By changing the setting of the plug 9, a maximum negative pressure is generated in the suction line 5. It was found, that this maximum negative pressure from the generation of standing waves in the mixing chamber 1 depends solely on the flow of fluid through the pressure inlet line 3, the mixing chamber 1 and the outlet line 6 is effected. The frequency of the standing Waves in the mixing chamber 1 can move in the same way as a trumpet their slider can be adjusted.

Die stehenden Wellen der gewünschten Frequenz können durch mechanische piezoelektrische oder elektromagnetische Schwingungserzeuger 10 und 11 verstärkt werden. Diese Schwingungserzeuger sollen nahe den Einmündungen der Leitungen 3 und 5 in die Mischkammer angeordnet sein und Resonanzschwingungen in den Strömungsmittelströmen erzeugen. The standing waves of the desired frequency can be created by mechanical piezoelectric or electromagnetic vibrators 10 and 11 amplified will. This vibration generator should be close to the junctions of the lines 3 and 5 be arranged in the mixing chamber and resonance vibrations in the fluid flows produce.

Eine praktische Einrichtung zum Verstellen des Stopfens, wie es in der Figur dargestellt ist, besteht aus einem Außengewinde auf dem Stopfen und einem Innengewinde in dem Block 2, der die Mischkammer umgibt. Durch Drehen wird der Stopfen 9 in dem Block verschoben. A practical device for adjusting the plug, as shown in of the figure consists of an external thread on the plug and one Internal thread in the block 2 surrounding the mixing chamber. Turning the stopper 9 moved in the block.
