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.
Claims10
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.
