Abstract
Blank washer for cleaning individual sheet metal blanks with a drawing compound liquid suitable for press operations which employs pressurized liquid vortex diffuser means to replace conventional scrubbing brushes. An enclosure with air knives at entrance and exit to the blank washer provides closed loop recirculating of both air and cleaning liquid, which is filtered and repumped to plenum chambers feeding individual vortex diffuser cylindrical outlets which discharge liquid vortexes in close proximity to the passing sheet metal.
