Abstract (en)
[origin: EP0693325A2] The workpieces (W) are moved through the cleaning process on an endless conveyor (12) passing through a cleaning chamber (18). High pressure air jets (30) in the chamber remove any loose debris from the workpieces with the return air flow passed back to the pump (34) via a mechanical filter (44) to remove particles. The cleaning chamber is divided into compartments by elastic bulkheads/shutters (20) to contain the debris. The contaminated air is collected and passed to the filter. Grease etc. can be loosened by steam jets in front of the air jets. Lost air is made up by a compressed air feed (48) between the filter and the pump. <IMAGE>
