A method and apparatus for cleaning the interior of storage tanks of the type used for storing large volumes of liquids, such as crude oil, wherein hydrocarbon sludge accumulates with the passage of time, such apparatus comprising a hollow housing, liquid agitation means including a plurality of nozzled outlet jets laterally rotatably mounted on the housing in fluid communication with the hollow interior thereof, connecting means comprising an independently rotatable tubular casing rotatably mounted on the housing in fluid communication with the interior thereof, the tubular casing having a kelly mounted therein and being operatively connected with the nozzled outlet jets, and multi-joint support pipe means rotatably joined to the connecting means in fluid communication with the interior of the tubular casing. With this construction, an appropriate pump means may be provided for forcing a liquid, such as crude oil through the multi-joint support pipe means into the hollow housing and out of the hollow housing through the nozzled outlet jets and indexing power means may suitably be provided and operatively rotatably connected to the laterally rotatable outlet jets for their rotation at a predetermined rate independent of the rate of flow of liquid through the nozzled outlet jets. |
