Abstract:
An auto-aspirating rotational dispersion device for gases and liquids comprising a hollow shaft (2) for gas suction rotatable in a first direction; gas channels (3, 3â€², 3â€³, 3â€²â€³) communicating with said hollow shaft (2) and extending outwardly therefrom and having a cross-section which increases in size in a direction from the hollow shaft (2), and a circumferentially positioned gas channel opening (4) at an end of each of said gas channels (3, 3â€², 3â€³, 3â€²â€³) and oriented in a second direction opposite the rotatable first direction of the hollow shaft (2); a lower cover disk (6) provided below said channels (3, 3â€², 3â€³, 3â€²â€³) and attached to an outer wall of the hollow shaft (2) and an annular upper cover disk (5) provided above said gas channels (3, 3â€², 3â€³, 3â€²â€³) and surrounding said hollow shaft (2) concentrically and forming an annular gap (7) with the outer wall of the hollow shaft (2); said upper cover disk (5), lower cover disk (6) and gas channels (3, 3â€², 3â€³, 3â€²â€³) forming compartments (8), said upper and lower cover disks (5,6) having respective outer radial peripheries, said gas channel openings (4) being positioned radially beyond the respective outer radial peripheries of said upper and lower cover disks (5,6) wherein when said device is rotated a gas to be dispersed flows in separate fashion from a liquid through the hollow shaft (2) over gas channels (3, 3â€², 3â€³, 3â€²â€³) to said circumferentially positioned gas channel openings (4) and liquid is sucked into said compartments (8) such that an intermixture of gas and liquid occurs outside of the dispersion device (1) in the area of the gas channel openings (4).
