AIR SUPPLY/EXHAUST DEVICE FOR SINTERED ORE COOLING MACHINE

WIPO Patent Application WO/2023/157779

A1

The present invention provides an air supply/exhaust device for a sintered ore cooling machine, the air supply/exhaust device being capable of preventing leakage of a gas or dust from a sealed portion between a trough carriage and a hood to the outside of the system even in cases where a gap is formed between the trough carriage and the hood due to long-term deterioration or the like.　An air supply/exhaust device 3 for a sintered ore cooling machine 1 according to the present invention is used for a sintered ore cooling machine 1 which cools sintered ores 15 by causing a cooling gas to pass through layers of the sintered ores 15 stacked on a plurality of trough carriages 5 that are covered by a hood 13. This air supply/exhaust device 3 is provided with: a cooling gas pressure feed device 7 which feeds the cooling gas below the plurality of trough carriages 5; an exhaust gas suction device 9 for discharging the exhaust gas from a space covered by the hood 13 to the outside; and a control device 11 which controls at least one of the cooling gas pressure feed device 7 and the exhaust gas suction device 9 so that the flow rate of the cooling gas is lower than the flow rate of the exhaust gas.
