Kind Code:
A
Abstract:
The present invention relates to a sludge dryer with increased retention time, comprising a main body having a space formed therein for the insertion and drying of sludge; an input formed in the upper part of the main body to introduce the sludge into the main body from the outside; a plurality of drying plates that are installed vertically in a multistage manner to dry the sludge by receiving the sludge introduced by the input and retaining the sludge; a shaft installed in the vertical direction at the center of the main body and rotated by the power transmitted from a central motor; one or more moving scrapers installed in the radial direction on the respective drying plates, and having a plurality of movers that are connected to the shaft and obliquely coupled at a predetermined interval so that the sludge supplied to the drying plates is gradually moved to the central part or the outer peripheral part of the drying plates while rotating; drop grooves that are respectively formed in an alternating fashion in the central part and the outer peripheral part in the upper and lower drying plates that are installed in a multistage manner such that sludge moved to the central part or the outer peripheral part of the drying plates can be dropped to a lower stage by the movers; and a supply pipe connected to a heat source via a hot air pipe and installed at the lower side of each drying plate so as to supply heat to the respective drying plates.
