SCALE DISCHARGE DEVICE

Disclosed is a scale discharging device. According to an embodiment of the present invention, the scale discharging device comprises: a hollow suction member extending in a width direction of a steel sheet and provided with a suction port for suctioning a scale and a foreign material at a position opposite to a surface of the steel sheet; a dust collector for suctioning and collecting scale and foreign material flowing into the suction member; a cylindrical suction inducement roll rotatably installed in the outside of the suction member with the suction member accommodated therein, rotating while being in contact with the surface of the steel sheet to which an outer surface is transferred, and having a plurality of through-holes to allow for inflow of the scale and foreign material around a circumference; and a diaphragm extending from the suction port of the suction member toward an inner surface of a suction inducement roll, and limiting a suction area of suction inducement roll through-holes by partitioning a space between the suction member and the suction inducement roll inner surface. Therefore, the present invention is capable of easily discharging the scale and floating foreign materials transferred along a surface of the steel sheet. 스케일 배출장치를 개시한다. 본 발명의 실시 예에 따른 스케일 배출장치는 강판의 폭방향으로 길게 연장되며 강판의 표면과 대향하는 위치에 스케일과 이물을 흡입하는 흡입구가 마련된 중공의 흡입부재; 흡입부재로 유입되는 스케일과 이물을 흡입해 집진하는 집진기; 흡입부재를 내부에 수용한 상태로 흡입부재 외측에 회전 가능하게 설치되고, 외면이 이송되는 강판의 표면에 접한 상태로 회전하며, 둘레에 스케일과 이물 유입을 위한 다수의 통공이 형성된 원통형 흡입유도롤; 및 흡입부재의 흡입구로부터 흡입유도롤 내면 쪽으로 연장되며, 흡입부재와 흡입유도롤 내면 사이의 공간을 구획해 흡입유도롤 통공들의 흡입영역을 한정하는 격막을 포함한다.
