An object of the present invention is to provide a disk-type screen dewatering device capable of excellent dehydration efficiency and preventing clogging of screen gaps by a rotating disk ring structure that rotates 360° while simplifying a power transmission mechanism. That is, the present invention is installed in the gas (1), the dehydration drum 10 in which the dehydration chamber 11 is formed; Containing; a transfer screw 20 installed in the dehydration chamber 11 and provided to be rotated by the driving unit 21, wherein the dehydration drum 10 includes a plurality of fixed disks fixed to the body 1 A plurality of rotating disk rings 16 installed between the ring 14 and the fixed disk ring 14 and rotated by 360°, and the spinning chamber while rotating on the inner circumference of the rotating disk ring 16 and the fixed disk ring 14 (11) It is characterized by consisting of a scraper bar (18) provided to remove the bottom sediment. The use of the disk-type screen dehydration device has the advantage that dehydration efficiency is highly improved, and in particular, the sediment at the bottom of the dehydration chamber is continuously removed by the scraper bar that rotates together with the transfer screw, so that the clogging of the fine screen gap is prevented even during long-time operation. have.
