The present invention relates to an electric
heat transfer fluid multi-stage horizontal disc dryer, and more specifically, to a technology for an electric
heat transfer fluid multi-stage horizontal disc dryer that can improve
drying efficiency by increasing the contact area with
livestock manure or
sludge by allowing the
heat transfer fluid to circulate widely through the discs used in the device for
drying livestock manure or
sludge. The present invention, as a technical means for solving the above problem, may be configured to include a disk body having a hollow interior, a plurality of blades provided on the outer circumferential side of the disk body, a heat transfer guide surface configured to divide the hollow portion of the disk body into inner and outer sides while having one side open, a first partition extending from the inner side of the disk body through the opening of the heat transfer guide surface to the center and coupled to the outer circumference of a shaft, a partition section comprising a second partition extending from the inner side of the heat transfer guide surface to the center and coupled between a heat transfer outflow hole and a heat transfer inflow hole formed on the outer circumference of the shaft, and a side plate configured in a plate shape corresponding to the hollow portion of the disk body, having a
coupling hole formed in the center through which a shaft passes, and
coupling such that the inner side faces the longitudinal ends of the heat transfer guide surface and the partition section while sealing both sides of the hollow portion of the disk body. A
sludge dryer equipped with a multi-stage horizontal disk according to the present invention comprises a main body portion having a receiving space formed therein for receiving sludge, a shaft provided along the longitudinal direction in the receiving space, and a disk provided in the circumferential direction of the shaft, wherein the shaft is configured with a first flow path and a second flow path while the hollow interior is divided by a partition wall, and in the circumferential direction, a heat transfer outlet is formed in the first flow path divided by the partition wall and a heat transfer inlet is formed in the second flow path; and the disk comprises a disk main body having a hollow interior, a plurality of blades provided on the circumferential outer side of the disk main body, a heat transfer guide surface configured to divide the hollow portion of the disk main body into inner and outer sides while having one side open, a first partition extending from the inner side of the disk main body through the opening of the heat transfer guide surface to the center and coupled to the outer circumferential surface of the shaft, and a component formed on the outer circumferential surface of the shaft extending from the inner side of the heat transfer guide surface to the center. It may be configured to include a partition section consisting of a second partition connected between a
heat flow outlet and a
heat flow inlet, and a side plate configured in a plate shape corresponding to the hollow portion of the disk body, with a connecting hole formed in the center through which a shaft passes, thereby sealing both sides of the hollow portion of the disk body and connecting such that the inner surface faces the
heat flow guide surface and both longitudinal ends of the partition section.
