PURPOSE:To reduce the height of a discharge apparatus of particulate body while securing the possibility for continuous discharge of particulate body and maintaining the air- tightness of an air-tight chamber by providing a transporting device in the air-tight chamber at the bottom of an outlet of the particulate body in a vertical cooling furnace and providing a rotary valve to an outlet of a vertical cooling furnace for the particulate body. CONSTITUTION:A vibrational feeder 7 which is a transporting device capable of sending out particulate body continuously and at a fixed rate is provided to the inside of an air-tight chamber 6 at the bottom of the outlet of particulate body of a vertical cooling furnace 2 of the particulate body, and a rotary valve 1 is provided at the same time to the discharge part of the transporting device 7. The transporting capacity of the transporting device 7 is constituted to be controllable to less than the holding capacity of each chamber constituting the valve 1. Thus, the device can discharge continuously the particulate body while maintaining the air-tightness of the furnace 2. Accordingly, an apparatus for storing the particulate body temporarily is unnecessary. Since the rotary valve is used to maintain the air-tightness of the furnace 2 without using a double sealing valve, therefore, the height of the furnace is reduced, and the height of the whole apparatus of the furnace is reduced and the installation cost is saved. |
