Abstract
A device for the heat treatment of bulk material comprising a horizontal trough-shaped container having a driven shaft extending longitudinally therethrough on which shaft are mounted radially extending arms on which are provided mixing tools and heat exchange plates removably suspended in the container between the mixing tools. A heating or cooling medium can be passed through the plates to heat or cool the bulk material.
Claims14
Apparatus for the heat treatment of bulk material, comprising:
- a generally horizontally extending trough-shaped container;
- a driven shaft extending longitudinally through and being mounted for rotation with respect to said container;
- a plurality of arms operatively secured to and extending generally radially outwardly from said shaft for rotation therewith, said arms having means for mixing bulk material within said container;
- a plurality of separate heat exchanger plates positioned within said container between said radially extending arms, and means mounted on side walls of said container for mounting each of said plates so that each plate is individually removable independently of each other and of said shaft, the cross-sectional configuration of said heat exchanger plates generally conforming to the internal configuration of said trough-shaped container, with each plate being formed with cutouts aligned with interfering parts within said container, including said shaft.
A heat exchange apparatus for the heat treatment of bulk material, comprising:
- a generally horizontally extending trough-shaped container;
- a driven shaft extending longitudinally through and being mounted for rotation with respect to said container;
- a plurality of arms extending generally radially outwardly from said shaft and having means for mixing bulk material within said container during rotation of said shaft;
- a plurality of heat exchanger plates separately mounted within said container between said radially extending arms so as to be individually removable independently of each other and said shaft, a hood generally closing the upper portion of said trough-shaped container and having therein at least one inlet and one outlet for process gas, said hood being provided with flow control means for directing the process gas from said inlet in a generally transverse path through said container to said outlet.
A heat exchange apparatus for the heat treatment of bulk material, comprising:
- a generally horizontally extending trough-shaped container;
- a driven shaft extending longitudinally through and being mounted for rotation with respect to said container;
- a plurality of arms extending generally radially outwardly from said shaft and having means for mixing bulk material within said container during rotation of said shaft;
- a plurality of heat exchanger plates separately mounted within said container between said radially extending arms so as to be individually removable independently of each other and said shaft, wherein said container has generally vertically extending side walls and a bottom, and each of said heat exchanger plates includes generally vertically extending peripheral side walls closely adjacent said vertically extending walls of said container, a slot extending from the bottom upwardly to immediately above said shaft to facilitate assembly without removal of said shaft, and lower remaining peripheral wall portions adjacent the container bottom and including a cut out portion providing an axial flow passage for bulk material, and a mechanical mixing head extending through said container into the bulk material axial flow passage radially opposite an adjacent heat exchanger plate, and power means for rotating said mixing head.
