Abstract
Sealing apparatus of wind boxes at both the ore charge and discharge sides of a Dwight-Lloyd sintering machine provides a plurality of seal members disposed in series in close contact with the bottom surface of pallets of the sintering machine, and a seal chamber communicating with a space provided between these seal members. The seal members are rotatable rolls having seal plates projectingly installed radially on the outer periphery thereof, and may be rolls with these seal plates held in close contact with the bottom surface of the pallets and the inner surface of the seal chamber, or may be flat seal plates with their flat surface firmly pressed against the bottom surface of the pallets. In the seal chamber is mounted an independent exhaust fan for the removal of air, further improving sealing performance. According to the apparatus, it is possible to decrease the amount of sintering exhaust gas, power consumption of main induced fan, and processing costs at subsequent desulfurization and denitrification equipment.
