Patent DE-3705814-A1 (DE)
Title: Dispersion apparatus
Inventor: BAUER MANFRED
IPC: B01F15/00
Filed: 1987-02-24
Abstract: A dispersion apparatus (1) is provided with a sleeve-like stator-shaft tube (2) in which is situated a drive shaft (4) connected to a drive (5). At the free end of the shaft tube (2), within a region of the shaft tube (2) furnished with side orifices (6), is situated a rotor (3) which is connected to the drive shaft (4). The drive shaft (4), before the point of connection to the rotor (3), is mounted in a bearing bushing (7). According to the invention, the drive shaft (4), starting from the bearing bushing (7), is conically tapering. As a result, a suction action otherwise appearing at high rotary speeds, in particular above 30000 1/min, is avoided by the liquid to be dispersed being transported up through the bearing bushing gap within the shaft tube (2). As a result, even very high rotary speeds can then be used and, as a result in turn, small-diameter rotors (3) and shaft tubes (2) can be employed. <IMAGE>
