BUTT SEALING OF AGGLOMERATION OR ROASTING CONVEYER-TYPE MACHINE Russian patent published in 1994 - IPC

FIELD: metallurgy. SUBSTANCE: sealing has a sealing member in the form of movable plates 1, that are fixed on free ends of elastic levers 2. The levers are rigidly connected with frame 3 and form a parallelogram in longitudinal section of the sealing. Each plate 1 has rigidly fixed arch-shaped part 4 of a cylindrical pipe with longitudinal axis 5. Sealing plate 6, made in the form of a two-arms lever, is hinged to axis 5. One end of the lever has load 7 and free rests at wall 8 of a vacuum chamber of the machine. The other end of the lever of plate 6 is located inside of arch-shaped part 4 of the cylindrical pipe and has minimum clearance between its free end and the inner surface of the pipe, that makes it possible for it to move along the arch of circumference relatively to the pipe. Tightening tool 9 is set between sealing plate 1 and frame 3. Frame 3 has vertical movement mechanism 12. Sealing is fixed to metal structures by bolts 13. EFFECT: increase of hermetic sealing. 2 cl, 1 dwg
