Abstract
A reduced size tank cleaning machine that has an impeller rotated by an inlet stream is disclosed. The impeller turns a shaft connected to a sealed planetary gear train that causes the tank cleaning machine to rotate about an axis, and this rotation causes a set of nozzles to rotate about a second axis. The fluid from the inlet stream exists through a port located between the impeller and the gear train and through the spray nozzles. Thus, the planetary gear train drives the tank cleaning machine about a first axis and a second axis. The design disclosed is preferably constructed so that it can be inserted into an opening that is about three inches (3.00'=76.2 mm) in diameter. Methods of cleaning vessels are also disclosed.
