Abrégé

A drier apparatus includes a cylindrical chamber in which a pair of screw conveyers each including a tubular shaft in which heat medium is able to flow, and carrier blades arranged on an outer surface of the tubular shaft is housed, a motor for rotating the screw conveyers, an input path connected to the cylindrical chamber at a proximal end of each of the screw conveyers, and an output path connected to the cylindrical chamber at a distal end of each of the screw conveyers. The input path and the output path include a device for opening and closing a path. Each of the screw conveyers includes a pair of tubular shafts arranged substantially in parallel with each other, and a plurality of semicircular carrier blades such that the carrier blades form a part of an imaginary spiral plane about the tubular shaft on an outer surface of the tubular shaft, the carrier blade being partially made of a material having a resistance to abrasion.

Provided is a drying device which is capable of efficiently and stably drying an object to be dried and has conveyance blades with excellent durability. A drying device 10 is equipped with: a cylindrical housing 7 which houses a pair of screw conveyors 100 that each have conveyance blades 8y on the outer periphery of a tubular shaft body 90y allowing a heat carrier to flow therethrough; a motor 11 which causes the screw conveyors 100 to rotate; an input path 7a which is provided so as to be continuous with the cylindrical housing 7 on the leader 100a side of the screw conveyors 100; and a discharge path 7b which is provided so as to be continuous with the cylindrical housing 7 on the end 100b side of the screw conveyors 100. The input path 7a and the discharge path 7b are provided with path opening/closing means 30, 40, respectively. The screw conveyors 100 are equipped with: a pair of tubular shaft bodies 90y which are arranged substantially parallel to each other; and a plurality of semicircular conveyance blades 8y which are mounted on the outer periphery of each of the tubular shaft bodies 90y so as to form a portion of the virtual spiral surface about the tubular shaft body 90y, the conveyance blades 8y being partially formed from an abrasion-resistant material.

A screw conveyor includes a plurality of shafts rotatable in a common imaginary plane, and a plurality of blades arranged on each of the shafts in an axial direction of the shafts such that the blades define a part of an imaginary spiral around the shafts, each of the blades being semicircular in shape when viewed in an axial direction of the shafts, a distance S being longer than a length D, but shorter than 2D, wherein “S” indicates a distance between outer surfaces of two shafts located adjacent to each other, and “D” indicates a length by which the blades extend from outer surfaces of the shafts.
