<p>The specification discloses a sealing apparatus for wind boxes at the ore supply side and ore discharge side of a DL type sintering machine, which is provided with a plurality of sealing members series-arranged in contact with the lower surface of a pallet in the sintering machine, and a seal chamber communicating with spaces between these sealing members. Each of the seal members consists of a rotatable rolls having radially projecting seal plates on the outer circumferential surface thereof. It may also consist of a roll having such radially projecting seal plates closely contacting the bottom surface of a pallet and the inner surface of a seal chamber, or a roll having flat seal plates the flat surfaces of which are pressed against the bottom surface of a pallet. Since an independent air extracting exhaust fan is provided in the seal chamber, the sealing performance can be further improved. According to this apparatus, the rate of generation of a sintering exhaust gas decreases, and electric power for a main fan and the processing costs for desulfurization and denitration apparatuses in the subsequent steps can be reduced.</p> |
