1. Apparatus for cleaning a liquid storage tank, comprising:
- a. a tube configured with a channel for conveying a liquid;
b. a shaft assembled within the tube and having a first axis;
c. a first housing assembled rotatably to the tube and caused to rotate around the first axis by the shaft;
d. a nozzle housing mounted to the first housing for being rotated by the shaft around a second axis that is substantially perpendicular to the first axis;
e. a plurality of radial nozzles formed through a periphery of the nozzle housing;
f. a plurality of downspray nozzles mounted to the first housing in a manner to rotate around the first axis, the downspray nozzles each residing substantially coplanar with the first axis;
g. wherein the radial nozzles and the downspray nozzles are in fluid communication with the liquid conveyed within the tube; and
h. wherein the first housing and the downspray nozzles rotate around the first axis and the nozzle housing and the plurality of radial nozzles rotate around the second axis.

Abstract
A rotary apparatus and method is provided for cleaning liquid storage tanks, particularly above ground tanks. The rotary cleaning apparatus includes a Tee housing that is rotated around a vertical axis and a nozzle housing mounted to the Tee housing for rotation around a horizontal axis, resulting in a 360° spherical spray pattern. A set of downspray nozzles is mounted to the Tee housing at an angle to the vertical axis to rotate with the housing and generate a conical spray pattern. In the preferred embodiment, the apparatus draws liquid stored in the tank through a filter and pumps the filtered liquid through the rotary cleaning apparatus.
