Abstract

A radial rotary dryer improves drying efficiency for sludge and other substances, prevents clogging phenomenon, and is realized in a simple structure. The radial rotary dryer includes spaces formed by inner and outer drums and partitioned by a plurality of radial plates. The substances, which have been introduced through a drum inlet together with hot blowing air, sequentially move throughout all spaces and are dried during drum rotation. The substances are discharged through an opposite side of the inner drum. A lift plate is attached at one surface of each radial plate to improve the drying efficiency. Hammers are attached to an opposite surface of the radial plate to free-fall according to the rotation of the drum, thereby crushing the substances. The radial rotary dryer is useful to dry sewage sludge, food waste, or other industrial substances with the best drying efficiency, the minimum installation space, and a crushing function.

Claims2

Dependent claims

A radial rotary dryer used for multiple purposes in various industrial fields, the radial rotary dryer comprising:

a drum (200) which includes an outer drum (201), an inner drum (202) provided inside the outer drum (201), a radial plate (203) radially interposed between the outer and inner drums (201, 202), a lift plate (204) attached to one surface of the radial plate (203), a drum inlet-side plate (210) and a drum outlet-side plate (211) positioned at both ends of the outer drum (201),
wherein the outer drum (201), the inner drum (202), the radial plate (203), the drum inlet-side plate (210) and the drum outlet-side plate (211) form a plurality of radial dry spaces (208),
wherein the inner drum (202) includes a drum inlet (230) used to introduce substances into the inner drum (202), an input port (206) used to introduce the substances into one of the radial dry spaces (208), an output port (207) receiving the substances dried while passing through the radial dry spaces (208), a drum outlet (231) discharging the substances that has been dried, and separation plates (205) blocking the substances, which has been introduced through the drum inlet (230), from moving to the drum outlet (231).

Dependencies are inferred from the claim text.
