Abstract

Mixer comprising an underframe and a motor-driven shaft, on which the mixing element is mounted and enters the mixing vessel through the bottom is modified thus: the underframe carries a plate below the bottom of the vessel to which the motor is fixed by means of a flange; the inner edge of the bottom of the vessel has a machined surface parallel to the surface of the plate; a seal is provided in the opening in the bottom of the vessel, consisting of a bush extending through the opening with a bore which is of greater cross section than that of the drive shaft, and having a radial flange at its upper end, which extends over and is supported on the machined inner surface of the bottom of the vessel; a fixed shaft seal ring mounted near the upper end of the bush, and a seal ring supported on and able to rotate round the shaft, the under surface of which is in smooth contact with the upper surface of the fixed seal ring; a spring pressing the rotatable seal ring against the fixed seal ring; a device for causing the rotatable seal ring to revolve simultaneously with the shaft.
