Title: Mixer esp. for pharmaceuticals, cosmetics, etc. - having external drive mechanism
Inventor: HORNOFF LEONHARD
IPC: B01F7/00
Filed: 1974-11-02
Abstract: In the mixer system for a vessel, >=1 agitator, held at its lower end in a rotary bearing, executes two separate movements, namely rotation about its own axis and rotation around the long axis of the vessel. The novelty lies in the fact that the whole of the drive mechanism for the agitator lies below and outside the vessel. The agitator extends into the vessel in a self-supporting fashion from one entry point and is carried in a spherical bearing. The agitator is axially fixed by a mixer arm and its motion is defined by mixer arm and a toothed-wheel drive. The design reduces the powder-explosion hazard and the possibility of contamination of the prod. with lubricants and worn bearing matls. The vessel is stationary and need not be designed to with-stand shock press. The vessel is easily cleaned and the drive mechanism has low maintenance requirements. Feed pipes for the prod. can be attached to the vessel.
