<p>The smoke removal vent device comprising a curved panel (6) arranged in the extension of similar panels made fixedly integral by their longitudinal edges on two sloping tuyere sides (1), is capable of being moved vertically, by the action of at least an actuator (7), while remaining horizontal. Said device comprises two articulated symmetrical assemblies (2), each integral with one of said tuyere sides (1) and said curved panels (6) not far from one of the longitudinal edges (60) thereof, articulated via horizontal pivots (31, 32, 411, 413, 430) parallel to said longitudinal edges (60), enabling, under the actuator (7) vertical thrust, said curved panel (6) to be vertically and linearly raised.</p> |
