A fluid-agitating tank assembly (1) comprising a tank (10), filled in use with a fluid, in particular a fluid with particles, and agitator means (11), housed in the tank (10) so as to be immersed in use at least partly in the fluid and supported by the tank (10) in a rotatable manner about an axis (D); the agitator means (11) comprise:
- a double helix (26) housed in an upper volume (27) of the tank (10) and acting in use on the fluid to transform unidirectional rotation of the agitator means (11) about the axis (D) into a bidirectional movement of the fluid in the tank (10) towards bottom and top portions (13, 14) of the tank (10), and
- at least one rotary blade (28, 28') projecting transversally from the axis (D), housed in a bottom volume (29) of the tank (10) and rotating in use about the axis (D) to move the fluid towards at least one lateral outlet (25) of the tank (10);
the tank assembly (1) further comprises at least one fixed blade (30) housed in the tank (10) and adapted to at least in part decouple from one another the fluid motions in the top and bottom volumes (27, 29) of the tank (10). |
