Die Erfindung betrifft eine Vorrichtung zum Homogenisieren von Flüssigkeiten oder verflüssigten Stoffen, bei der die Flüssigkeit zwischen zwei gegeneinander gepreßten Flächen hindurchgedrückt wird, wobei die eine der beiden Flächen eine rotierende Bewegung ausführt, so daß die Flüssigkeit zwischen den beiden Flächen zerrieben wird. Bei den bekannten Homogenisierapparaten läuft nun dieThe invention relates to a device for homogenizing liquids or liquefied liquids Substances in which the liquid is pressed through between two surfaces pressed against one another, one of the both surfaces executes a rotating movement, so that the liquid between the both surfaces is rubbed. With the known homogenizers, the

As a result, grooves very soon form in the friction surfaces, and the consequence of this is that the homogenization becomes imperfect.

Um diesen Übelstand zu beseitigen, ist bei dem Homogenisierapparat nach vorliegender Erfindung die rotierende Fläche exzentrischIn order to eliminate this drawback, the homogenizer according to the present invention Invention the rotating surface is eccentric

ao gegen die andere Reibfläche geführt, derart, daß erstere bei der Drehung um ihre Achse in beständig sich ändernden Kurven gegen die letztere läuft. Auf diese Weise wird erreicht, daß eine völlig gleichmäßige Abnutzung der beiden Reibflächen stattfindet und die Bildung von Rillen in denselben verhindert wird. In der Zeichnung ist die Vorrichtung in beispielsweiser Ausführungsform im Längsschnitt dargestellt. Sie besteht aus einem Gestell a, an welches ein Rohrstück b angeschlossen ist, in das der Homogenisierkörper c eingesetzt ist. In dem Gestell ist eine Spindel d = gelagert, die mit dem Homogenisierkörper e derart verbunden ist, daß letzterer zur Mittelachse der Spindel versetzt ist. Um die Spindelao against the other friction surface in such a way that the former runs against the latter in constantly changing curves when it rotates about its axis. In this way it is achieved that a completely uniform wear of the two friction surfaces takes place and the formation of grooves in the same is prevented. In the drawing, the device is shown in an exemplary embodiment in longitudinal section. It consists of a frame a to which a pipe section b is connected, into which the homogenizing body c is inserted. A spindle d = is mounted in the frame and is connected to the homogenizing body e in such a way that the latter is offset from the central axis of the spindle. To the spindle

Claims

Patent Claims:

a guide bushing f is arranged through which the spindle passes freely and whose wall thickness is from one side to the opposite! Side gradually decreases. The spindle d is set in rotation by the pulley g in that it is carried along by a web engaging in the spindle. The pulley is also connected to the gear h . The latter is in engagement with the gear i, which is seated on the shaft m and which is connected to the gear k . The gear wheel I , which meshes with the wheel k, is attached to the guide sleeve f . The homogenizing body β is pressed against the body c with the aid of a screw bolt η. The liquid enters through the pipe section b and drains through the pipe socket 0 .

By rotating the drive disk g , the homogenizing body e is set in rotating motion. Through the intermediary of the gear mechanism h, i, k, I , the guide bushing f is also rotated in such a way that the speed of rotation of the latter is about half that of the spindle d . As a result, the homogenizing body e runs against the body c in curves that are constantly changing, there is a continued displacement of the two bodies against each other.

I. Device for homogenizing liquids or liquefied substances,

in which the liquid is pressed through between a stationary and a rotating surface pressed against it, characterized in that the spindle (d) of the rotating body (e) is guided eccentrically.

2. Apparatus according to claim i, characterized in that an eccentric guide bush (f) is arranged around the spindle (d) of the rotating homogenizing body (e) , the rotational speed of which is different from that of the spindle (d).

3. Apparatus according to claim 1 and 2, characterized in that the homogenizing body (e) is offset to the central axis of the spindle (d).
