Abstract
A swing diffuser apparatus for gas diffuser systems for liquid treatment is disclosed in which an array of diffusers (50) is movable between a deeply submerged, essentially horizontal operating position, a shallowly submerged, essentially horizontal operating position, and a fully exposed, substantially upright position at the edge of the container for the liquid. An articulated hanger arm linkage (22, 24, 26, 30, 32, 52, 54) rotates the array to achieve these positions as the linkage folds and unfolds.
Claims12
A swing diffuser apparatus for gas diffuser systems of the type in which diffusers are submerged in a tank of liquids to be treated, said apparatus comprising:
- a rigid upper hanger arm;
- means for pivoting said upper hanger arm to or adjacent to said tank for movement in a generally upright plane;
- a rigid lower hanger arm;
- means for pivoting said lower arm to said upper arm for movement in said generally upright plane or a parallel plane;
- an array of gas diffusers pivotably connected to the lower portion of said lower hanger arm, said array having a substantially horizontal operating position when submerged in said liquids;
- and
- means cooperating with said upper hanger arm and said diffuser array for rotating said diffuser array from said substantially horizontal position to an upwardly extending servicing position above the surface of said liquids at the side of said tank, said rotating occurring as said upper hanger arm is pivoted to a servicing position extending upwardly from said means for pivoting said upper hanger arm.
