A thermal expansion adaptive sintering flue gas circulation hood

Abstract

The present invention relates to a sintering fume circulation hood with adaptive thermal expansion, comprising a fume hood track disposed on both sides of a sintering trolley. A plurality of interconnected fume hoods are disposed on the fume hood track, each of which is connected to a frame. The bottom of the frame is provided with wheels capable of rolling along the fume hood track. When the fume hoods thermally expand during the sintering process, the wheels of the individual fume hoods can roll along the fume hood track, causing the fume hoods to shift and adaptively offset deformation caused by thermal expansion. The interiors of the fume hoods are interconnected, with the front end of the foremost fume hood and the rear end of the rearmost fume hood both connected to end plates. Scrapers are hingedly connected to the bottoms of the end plates. Sealing assemblies are symmetrically disposed within the fume hoods, hermetically sealed to the sintering trolley. The present invention improves the airtightness of the sintering fume circulation hood and prevents fume leakage.
