CLEANING EQUIPMENT FOR THE CLEANING OF TANKS

摘要

Within the foodstuffs, the pharmaceutical and corresponding industries, it is of the utmost importance that the insides of tanks and the equipment existing herein can be held completely clean without the risk of undesired bacterial growth, cross-contamination etc. Equipment for the cleaning of tanks comprises a submerged pipe with a nozzle head mounted on the bottom, through which nozzles cleaning fluid is sprayed from below and upwards, while at the same time the nozzles are rotated and turned around inside the tank. In order to ensure an effective cleaning of this submerged equipment, according to the invention this equipment is configured so that cleaning fluid is constantly led out over the pipe (7) which extends down into the tank. This leading-out (18, 19, 22) is effected partly via a channel (17) in the bearing bush (15) for the pipe (7) in the housing (4) for the formation of a film of fluid (19) on the pipe (7), and partly via a channel (16) or a separate nozzle (20) in the housing (4) for the formation of a cleaning jet (18, 22) directed towards the pipe (7).
