1. A heat exchange device for a powder and granular material, which comprises:
a casing having an elongated structure that extends horizontally; supports supporting the casing; front and rear ports respectively configured to supply a powder and granular material into and out of the casing, the front and rear ports being arranged at front and rear ends of the casing; two hollow shafts each haying an axis and holes extending radially from the axis, the two hollow shafts being rotatably supported within the casing and extending in parallel from the front end to the rear end of the casing, and the two hollow shafts rotating in opposite directions relative to each other within the casing; a plurality of heat exchangers joined to each hollow shaft at predetermined intervals along each hollow shaft, each plurality of heat exchangers being in fluid communication respectively with a corresponding hollow shaft of the two hollow shafts by the holes of the corresponding hollow shaft, and the plurality of heat exchangers rotating together with each corresponding hollow shaft within the casing: each of the plurality of heat exchangers comprising:
opposing plates having plate surfaces joined together into a hollow disk-shaped heat exchanger including two cutout recess parts respectively arranged at two symmetrical positions about the common axis of each hollow disk-shaped heat exchanger, each cutout recess part extending from a circumferential edge of the hollow disk-shaped heat exchanger toward the common axis of the hollow disk-shaped heat exchanger,the plate surfaces of the opposing plates being joined together and forming two wedges each having wedge-shaped plate surfaces extending between the two cutout recess parts, the wedge-shaped surfaces pressing the powder and granular material by rotation of the hollow disk-shaped heat exchanger, the wedge-shaped plate surfaces having a gradually increasing distance between the plate surfaces relative to the common axis of the hollow disk-shaped heat exchanger from a starting side edge of one of the two cutout recess parts to an ending side edge of another of the two cutout recess parts in the rotating direction and along the circumferential edge of the hollow disk-shaped heat exchanger, and each hollow disk-shaped heat exchanger further including:
a projection smoothly and circumferentially bulging toward the common axis of the corresponding hollow shaft and outwardly from an interior of each hollow disk-shaped heat exchanger,the projection having an opening located at a center of each hollow disk-shaped heat exchanger receiving the corresponding hollow shaft and the opening having a peripheral edge extending about the circumference of the corresponding hollow shaft and abutting a peripheral edge of a cylindrical sleeve, andthe peripheral edge of the opening of each hollow disk-shaped heat exchanger and the cylindrical sleeve being secured to the corresponding hollow shaft and each other about the circumference of the shaft; and cylindrical sleeves arranged around each hollow shaft and having the peripheral edge extending about the circumference of each hollow shaft, each cylindrical sleeve being interposed between neighboring hollow disk-shaped heat exchangers arranged along a length of each hollow shaft and being joined to the projections of the neighboring hollow disk-shaped heat exchangers and to the corresponding hollow shaft, wherein the two cutout recesses of the plurality of disk-shaped heat exchangers disposed on each hollow shaft are identically arranged along each hollow shaft relative to the axial direction and the rotating direction of each hollow shaft when viewed along the axial direction of each hollow shaft, and wherein the two hollow shafts rotate in opposite directions with portions of the hollow disk-shaped heat exchangers above each hollow shaft moving toward each other and portions of the plurality of hollow disk-shaped heat exchangers below each hollow shaft moving away from each other. |
