Abstract:
A compulsory mixer comprising:a mixing chamber having two opposite ends, an open top and a bottom defined from two horizontally disposed, parallel, and interfering cylindrical shapes generated from one of the opposite ends extending to the other of the opposite ends, the two horizontally disposed, parallel and interfering cylindrical shapes having axes extending parallel to and through the static mixing chamber; two centrally disposed, elongate, rectilinear discharge openings in the bottom of the mixing chamber, each opening extending from one of the opposite ends parallel to the axis of the horizontally disposed, parallel and interfering cylindrical shapes and defined from an end at the bottom of the static mixing chamber to the middle of the bottom of the mixing chamber whereby the two centrally disposed elongate rectilinear discharge openings form a substantially continuous opening along the bottom of the static mixing chamber from one end of the mixing chamber to the opposite end of the static mixing chamber; two mixing paddle systems, each system mounted for rotation about the axis; two eccentrically mounted, elongate, rectilinear gates positioned for rotational movement into and out of sealing relation to the centrally disposed, elongate, rectilinear discharge openings in the bottom of the mixing chamber; bearings at either end of the eccentrically mounted elongate rectilinear gates for permitting the gates to mount for rotation into and out of sealing relation relative to the mixing chamber; and, gate rotating means at the respective mixer chamber ends for moving the respective gates between sealing and dumping positions with respect to the mixing chamber bottom.
