Abstract
The invention relates to a dispersion tool (4) that can be cleaned more easily. For this purpose, the dispersion rotor (8) is arranged on the dispersion tool (4) axially moveable between the working position in the shaft tube (5) and the cleaning position outside the shaft tube (5), the dispersion rotor (8), in the cleaning position, being preferably completely arranged outside the shaft tube (5) and therefore being more easily cleanable.
Claims25
A dispersion tool (4) with a shaft tube (5) and a rotor shaft (6) rotatable in the shaft tube (5), wherein a dispersion rotor (8) is arranged on a free end (7) of the rotor shaft (6) such that the dispersion rotor (8) is drivable by the rotor shaft (6), wherein, the rotor shaft (6) is axially displaceable relative to the shaft tube (5) to displace the dispersion rotor (8) between a working position located inside the shaft tube (5) and a cleaning position located outside the shaft tube (5) wherein, a radial bearing (12) is located between the rotor shaft (6) and the shaft tube (5), and, wherein, the rotor shaft (6) has a reduced-diameter section which is axially aligned with the radial bearing (12), with the dispersing rotor (8) being in the cleaning position, to define a flushing gap (14) between the reduced-diameter section of the rotor shaft (6) and the radial bearing (12).
A dispersion device (1) comprising:
- a drive unit (3) having a power unit (2);
- and
- a dispersion tool (4) mounted to the drive unit (3), the dispersion tool (4) including a shaft tube (5) and a rotor shaft (6) rotatable in the shaft tube (5), wherein a dispersion rotor (8) is arranged on a free end of the rotor shaft (6) such that the dispersion rotor (8) is drivable by the rotor shaft (6), wherein, the rotor shaft is axially displaceable relative to the shaft tube (5) to displace the dispersion rotor (8) between a working position located inside the shaft tube (5) and a cleaning position located outside the shaft tube (5),
- wherein, the drive unit (3) is equipped with a magnet (35) to create a magnetic coupling between the drive unit (3) and the rotor shaft (6) to allow turning torque from the power unit (2) to be transmitted to the rotor shaft (6).
