EINHEITLICHER, EINSTÜCKIGER, DREHBARER MISCHER UND ABGABEKOPF

摘要

The mixer and disperser head (1) comprises a cylindrical, tubular mixing chamber (3) having a plurality of equally angularly spaced discharge slots (7) through its periperal wall, a first plurality of impeller blades (11) rigidly connected to one axial end of the mixing chamber (3), a second plurality of impeller blades (27) rigidly connected to the other axial end of the other end of the mixing chamber (3), and a shaft (15) rigidly connected to the first plurality of impeller blades (11) coaxially with and situated quite outside the mixing chamber. The first (11) and second (27) pluralities of impeller blades being mirror-images of each other relatively off-set by an angle of 60 DEG about the rotational axis (5) of the mixer and disperser head (1). The first plurality of impeller blades (11) consists of three identical blades (17) angularly off-set by 120 DEG for each other. Each blade (17) comprising a portion (19) which is leading in the rotational direction (R) of the mixer and dispenser head (1) and a trailing portion (21) forming an inward obtuse angle with the leading portion (19). The leading portion (19) has a first part (23) lying in a plane perpendicular to the axis (5) of rotation and spaced from the one end of the mixing chamber (3) and a second part (24) bent inward about 90 DEG from the first part (23) and rigidly connected such as by welding (9) to the rim of said one end of the mixing chamber (3).
