Abstract

A tank washing system comprising three rows (16, 20, 21) of jet nozzles each row connected to a supply pipe (14) extending across the tank, and means (17, 18, 22, 24, 23, 25) for progressively rotating each supply pipe such that nozzles (16) swing forwardly and upwardly towards nozzles (20) which then take over and swing forwardly towards nozzles (21) which then continue to swing forwardly and upwardly. Thus, washing medium fed to the pipes (14) is directed in a wide footprint, at the tank bottom (12) and generates a surge or wave which sweeps along the tank bottom from one end to the other and entrains settled solids therein.
