Device for dispersing or homogenizing with a magnetic coupling drive for rotors in a chamber

摘要

A device (1) that is used to disperse or homogenize according to the flow-through principle, that includes at least one tool having a rotor (2) and a stator (3), expediently, several tools of this type that are arranged in an axial manner behind one another, that are arranged in a chamber (4) through which a medium that is to be treated flows. The rotor(s) is/are driven by a motor (6) via a magnetic coupling (5) and the magnetic coupling (5) has a stationary separating can (9) between a drive-sided, rotationally-driven drive coupling part (7) and a driven coupling part (8), such that expensive cooled shaft seals can be avoided. The drive coupling part (7) that is on the drive side engages in a recess-shaped or hollow cylindrical driven coupling part (8) that is on the driven side and the separating can (9) is arranged between the coupling parts. As a result, the driven coupling part (8) and the separating can are cooled by the medium that is processed.

1. Device (1) for dispersion or homogenization according to a continuous-flow principle, comprising at least one tool having at least two coaxial rotors (2) each provided with an associated stator (3) arranged within a chamber (4) carrying a flow of a medium to be processed, bearings for the rotors are arranged in the chamber (4) and the rotors (2) are driven by a magnetic coupling (5), the magnetic coupling (5) has a stationary separating can (9) closing the chamber (4) in a coupling region between a drive-side rotationally-driven drive coupling part (7) and a driven coupling part (8), the drive-side drive coupling part (7) engages as a magnetic carrier into a recessed or hollow of the driven-side coupling part (8), the separating can (9) is arranged between the two coupling parts and the outer driven-side coupling part (8) carries or is connected to a drive shaft (10) located in the chamber (4) for the rotors (2),and the bearings (11) for the rotors carried by the drive shaft (10) are arranged within the chamber (4) carrying a flow of the medium adjacent to the rotors (2), and at least one of the coaxial rotors is supported in a cantilevered manner with respect to one of the bearings.
