Swinging agitator for a gypsum calcining apparatus and the like

DETAILED DESCRIPTION The present invention provides for an agitation mechanism for a gypsum processing apparatus which includes a housing having a bottom wall, and at least one side wall.
The housing can be constructed and arranged to receive and process gypsum-based products.
A fluidization mechanism can be provided for delivering fluid to the gypsum-based products.
An agitator frame having a similarly shaped cross-section to the cross-section of the housing is provided and positioned adjacent the bottom wall of the housing.
The agitator frame is pivotally connected internally to the housing for reciprocating movement between first and second positions.
The agitation mechanism is operable for preventing channeling of the fluid through the gypsum, ensuring good fluidization, and preventing gypsum product from collecting adjacent the bottom wall of the housing.
The agitation mechanism can include a plurality of agitation members connected to the frame for agitating the gypsum product adjacent the bottom wall when the agitator frame moves.
The agitation mechanism can also include at least one pivotal support arm for pivotally connecting the frame to the apparatus.
The agitation mechanism can be used in a fluidized stucco cooler utilizing water injection.
The agitation mechanism can be used in a fluidized bed stucco cooler utilizing cooling coils.
Further, the agitation mechanism can also be used in a post-stucco treatment retention device.
A method is provided for agitating gypsum based material in a processing housing.
The gypsum based material is delivered to the housing, and an agitation mechanism having a frame with agitation members attached thereto is positioned adjacent the bottom wall of the housing.
The agitation mechanism is moved between first and second positions to agitate the fluidized material in the housing to prevent material from coagulating near the bottom of the housing and to prevent fluid channeling and dead zones of non fluidized gypsum.
Other applications of the present invention will become apparent to those skilled in the art when the following description of the best mode contemplated for practicing the invention is read in conjunction with the accompanying drawings
