Exhaust belt type cooler blast device

The utility model relates to an exhaust belt type blower device of a cooling machine, which is used for rebuilding the cooling equipment of sintered ore. The utility model is mainly composed of a centrifugal blower (18), an air pipe (16), air boxes (9), side sealing device sealing devices, end sealing devices, etc. The blower (18) and the air pipe (16) is communicated with each other by a special pipe (17); 6 to 20 air boxes (9) are continuously arranged in a cooling section which is under an upper trolley (12) of a belt type cooling machine; the air boxes (9) and the air pipe (16) are communicated with each together by a branch pipe (8); each 3 to 5 air boxes (9) is provided with a blower (18). When the blast device is compared with an exhaust device, the temperature of the sintered ore can fall to less than 150 DEG C from 200 DEG C.
