Description

[Technical field]

[0001] The present invention relates to the technical field of slag removers, particularly to air-cooled dry slag removers. [Background technology]

[0002] In an air-cooled dry slag remover, high-temperature slag falls continuously onto the slag remover conveyor, which moves at a slow speed to gradually cool the slag as it is transported. An intake fan is installed at the discharge port, and a limited amount of cold air enters the slag remover in the reverse direction to exchange heat with the high-temperature slag, thereby cooling the slag. The air temperature after cooling rises and enters the furnace body to promote combustion.

[0003] Most conventional air-cooled dry slag removers are equipped with an air suction device at the discharge port, which generates dust when sucking in air and discharging the material. In addition, because the air suction position is on the underside of the conveyor, some of the dust is blown onto the conveyor and adheres to and accumulates on the conveying surface, affecting the use of the conveyor. Furthermore, when discharging the material, it is necessary to clean the conveyor using a vibration device, but because of the air suction device, a lot of dust can fly up during cleaning.
