Abstract

Es wird eine Vorrichtung (1) zum Homogenisieren und/oder Dispergieren fließfähiger, insbesondere flüssiger oder pastöser Stoffe als Stoffvorlage bereitgestellt, welche einen Behälter (2) für die Stoffvorlage und eine motorbetriebene Homogenisier- und/oder Dispergiereinrichtung (6) umfaßt. Die Stoffvorlage wird von einem Behälterauslaß (4) mittels einer Förderpumpe (5) zur Homogenisier- und/oder Dispergiereinrichtung (6) gefördert, welcher gegebenenfalls Eintragseinrichtung (9) für Additive in flüssiger oder pulvriger Form zugeordnet sind. Die Homogenisier- und/oder Dispergiereinrichtung (6) gestattet gegebenenfalls auslaßseitig eine Rückförderung in den Behälter (2). Nach der Erfindung ist die Förderpumpe (5) gesondert zur Homogenisier- und/oder Dispergiereinrichtung (6) angetrieben, und es ist ein Sensor (14), vorzugsweise ein Drucksensor, zwischen dem Pumpenauslaß und der Einlaßseite der Homogenisier- und/oder Dispergiereinrichtung (6) angeordnet. Der Sensor (14) steuert den gesonderten Antrieb (8) der Förderpumpe (5) variabel nach Maßgabe der Fließeigenschaften der Stoffvorlage und/oder entsprechender Prozeßparameter derart, daß die Produktstromführung zur Homogenisier- und/oder Dispergiereinrichtung (6) immer unter Vordruck erfolgt.

There is provided a device (1) for homogenizing and / or dispersing flowable, in particular liquid or pasty substances as a fabric master, which comprises a container (2) for the fabric master and a motorized homogenizer and / or disperser (6). The fabric feed is conveyed from a container outlet (4) by means of a feed pump (5) to the homogenizing and / or dispersing device (6), which optionally are assigned to feed means (9) for additives in liquid or powder form. The homogenizing and / or dispersing device (6) optionally permits discharge on the outlet side into the container (2). According to the invention, the feed pump (5) is driven separately to the homogenizing and / or dispersing device (6), and there is a sensor (14), preferably a pressure sensor, between the pump outlet and the inlet side of the homogenizing and / or dispersing device (6 ) arranged. The sensor (14) controls the separate drive (8) of the feed pump (5) variable according to the flow characteristics of the stock and / or corresponding process parameters such that the product flow to the homogenizing and / or dispersing (6) always takes place under pre-pressure.
