Abstract
Material treatment apparatus includes a vibrating conveyor and a gas flow system for fluidizing particles on the conveyor as they move through the treatment zone. Containment structure extends along the length of each side of the treatment zone and includes a side wall surface portion affixed to and movable with the conveyor and a cooperating fixed structure with an edge closely adjacent but spaced from the surface portion that defines an elongated orifice extending along each side of the treatment zone. Gas flows through each orifice and downwardly along each side wall surface towards the treatment zone and provides effective containment action that prevents particles on the conveyor from passing laterally from the treatment zone.
Claims10
A material treatment system comprising
- a conveyor having a transport surface for transporting particulate material through a treatment zone,
- a drive for imparting vertical reciprocatory motion to said transport surface,
- a gas flow system for fluidizing particles on the transport surface as they move through said treatment zone,
- said conveyor including side wall structure extending along the opposed sides of said treatment zone throughout the length thereof,
- each said conveyor side wall structure including an inwardly facing vertical surface portion that extends the length of said treatment zone and is mounted for vertical reciprocatory motion with said conveyor transport surface,
- fixed edge structure closely adjacent each said inwardly facing vertical surface portion that defines an elongated orifice between said fixed edge structure and said vertical surface portion, and
- means for flowing gas through each said orifice and vertically downwardly along each said vertical side wall portion for containing particulate material within said treatment zone.
