Appl. No.:

8/101594

Inventors:

Daniel J. Bein - Waukesha WI

Assignee:

Oven Systems, Inc. - Milwaukee WI

International Classification:

F26B 1900

US Classification:

34424

Abstract:

A system for drying municipal sludge to reduce its moisture content and harmful pathogens to a level suitable for direct land application includes a cellular conveyor belt defining pockets which are filled with moist sludge and which is carried through multiple runs in a drying chamber over heat conducting supporting pans in a manner causing inversion of the sludge filled belt for at least one of the runs. Heated drying air is supplied directly to the sludge from above along each run and indirectly by conduction to the sludge from the supporting pans below along each run to provide uniform and rapid drying with maximum efficiency.

Abstract:

A quick disconnect supply riser for the nozzles of a can washing apparatus includes a bayonet connector and a riser support which provide inherent nozzle alignment when the risers are locked in connected position. Operator access to the capped opposite ends of the risers allows easy disconnection and reconnection via convenient openings in one side wall of the housing. The demountable connectors are attached to riser supply manifolds adjacent the opposite side wall thereby eliminating a large amount of excess piping.
