ABSTRACT:
An apparatus for cleaning the interior of storage tanks of the type used for storing large volumes of crude oil wherein hydrocarbon sludge accumulates with the passage of time. The apparatus comprises a crude oil circulator having rotatable nozzles positioned within the tank, a gear member externally disposed on an outer surface of a hollow rotor, and a worm gear operatively connected to the gear member. A drive shaft is connected, through a valve opening in the tank wall, to a motor unit. Upon failure of the worm gear, the worm gear is removed from the tank through the valve opening, replaced or repaired, and reintroduced into the tank through the valve opening.
