Abstract

The invention relates to a mixer for generating a flow of liquid, comprising a stationary body, an axially extending drive shaft protruding from said stationary body, a propeller, and a clamping sleeve assembly configured to interconnect the drive shaft and the propeller with each other in order to transmit a rotational motion. The clamping sleeve assembly has an axial clamping length, the clamping sleeve assembly comprising an inner clamping sleeve (7) and an outer clamping sleeve (8), wherein the inner clamping sleeve (7) has the shape of a tubular wall (9) having an inner surface (10) abutting the drive shaft and an outer surface (11) abutting the outer clamping sleeve (8) and wherein the outer clamping sleeve (8) has the shape of a tubular wall (12) having an inner surface (13) abutting the inner clamping sleeve (7) and an outer surface (14) abutting the propeller. The mixer is characterized in that both the inner surface (13) of the outer clamping sleeve (8) and the outer surface (11) of the inner clamping sleeve (7) are cylindrical along the axial clamping length, the inner surface (10) of the inner clamping sleeve (7), along the axial clamping length, having the shape of a truncated cone diverging towards a first end of the inner clamping sleeve (7), wherein the outer diameter of the inner clamping sleeve (7) is less than the inner diameter of the outer clamping sleeve (8) when both are unloaded, and wherein the tubular wall (9) of the inner clamping sleeve (7) comprises a slot (15) extending along the entire axial length of the inner clamping sleeve (7) and the tubular wall (12) of the outer clamping sleeve (8) comprises a slot (16) extending along the entire axial length of the outer clamping sleeve (8).
