COOLING APPARATUS FOR WING OF SCREW CONVEYER OF CARBONIZATION FURNACE OF WOOD CHIP

摘要

The present invention relates to a cooling device for a screw conveyor blade of a waste wood carbonization furnace. In the screw conveyor for stirring and transporting waste wood installed in the carbonization furnace, a tubular screw shaft having a channel (1a) through which cooling water can flow is formed. In the main surface of 1), the spiral screw blades 2 are formed as independent blades 2 in units of a pitch of 360 degrees, and inside the blades 2, a water chamber 2a through which cooling water can be introduced is formed. Cooling water circulated to the water passage 91a of 1) enters the water chamber 2a of the wing 2 through the water passage 1b formed on the main surface of the shaft 1, and the blade of the screw conveyor It is to prevent deformation.
