Agitator device

A non-close-clearance agitator device with respect to a vessel wall comprising:

• at least one agitation shaft, which in at least one operational state rotates about an agitation axis of the agitator device;
• and
• at least one outer agitation blade which is held on the agitation shaft and which in at least one section is implemented so as to be arm-shaped,
• a first outer agitation blade hub, a further outer agitation blade hub, a first bar and a second bar,
• wherein
• the outer agitation blade has an average width, which is a largest average expanse of the outer agitation blade perpendicular to the agitation axis,
• the outer agitation blade has at least one further section which is adjacent to the section and in which the outer agitation blade is implemented so as to be wider than in the section, the further section has an average width which exceeds an average width of the section by a factor of at least 2,
• the further section in relation to at least one operational position is arranged in a lower region of the agitator device, and
• the outer agitation blade in the section is connected to the first outer agitation blade hub by means of the first bar and the outer agitation blade in the further section is connected to the further outer agitation blade hub by means of the second bar.
