SEALING ASSEMBLY FOR THERMAL TREATMENT OVENS USING AN ATMOSPHERIC GAS CONTAINING GASEOUS HYDROGEN.

摘要

CLOSURE DEVICE (3) PROVIDED FOR AN ENTRY AND / OR DEPARTURE OF AN AREA OF A THERMOTRAINING OVEN USING A GAS ATMOSPHERE CONTAINING HYDROGEN, TO PERFORM A THERMOTTRATION AS HEAT HEATING, OR HEAT HEATING COFFEE DEFORMATION ETC. UNDER A STATE IN WHICH AN OXIDE FILM IS NOT FORMED ON THE SURFACE OF A METAL BAND, PRESSING A ROTARY ROLLER (6) ON A FLEXIBLE PAD (5) FIXED TO THE SURFACE OF A CLOSING PLATE (4) AND METAL BAND (S), TO CLOSE HERMETICALLY WITH REGARD TO OUTDOOR AIR, A FLEXIBLE PIECE (9) IS DISPOSED, IN A HOLE WITH OUTPUT (2B), DRILLED IN A POSITION THAT CORRESPOND TO BOTH SIDE EDGES OF FLEXIBLE PAD (FLEXIBLE PAD 5) ), ON A SIDE PLATE (2A) OF THE OVEN WALL (2), AND A MOBILE FLEXIBLE MECHANISM (10) PRESS THIS FLEXIBLE PLATE (9) TOWARDS THE SIDE FLEXIBLE PAD SURFACE (5). IN ADDITION, WHEN AT LEAST TWO SLIDING DISCS (7) OVERLOADS ONE OVER THE OTHER IN A ROLLER AXLE (6A), BETWEEN THE SIDE PLATE (2A) OF THE OVEN WALL (2), TO WHICH THE FLEXIBLE ROTARY ROLLER IS COUPLED (6), AND A MAIN BODY (6C) OF THE FLEXIBLE ROTARY ROLLER (6) IN THE AXIAL DIRECTION FROM THE SIDE OF THE MAIN BODY OF THE ROLLER (6C), AND A FLEXIBLE DISK (8) ARE COUPLED IN CONTACT OF MUTUAL SURFACE, THE COEFFICIENT OF DYNAMIC FRICTION BETWEEN THESE SLIDING DISCS, (7) OVERLOADS BETWEEN THE EXISTING ELEMENTS OF THE MAIN BODY OF THE ROLLER (6C), REGARDING THE SIDE PLATE (2A) OF THE OVEN WALL (2) IS SELECTED TO BE FROM THE MINING VALUE.
