Abstract
The utility model discloses a furnace door self-sealing device for a small and medium size bogie-hearth resistance furnace. The furnace door self-sealing device comprises a furnace door side sealing mechanism and a furnace door upper sealing mechanism. The furnace door side sealing mechanism abuts against one side of a driving oscillating bar through an oscillating bar spring which is mounted in a groove of a table top of a bogie. Under the condition that the middle of the driving oscillating bar is fixed by a fixing shaft, the top end on the other side of the driving oscillating bar transmits force to a furnace door side sealing cradle through a connecting rod, and accordingly the compressing movement and the loosening movement can be generated. Due to the fact that the position of one end of a furnace door upper sealing cradle is fixed by the fixing shaft, the middle is connected to a furnace door hanging bracket through a hanging bracket spring, and thus the furnace door upper sealing mechanism can be opened and closed conveniently. Ceramic fibers are arranged both on the inner side of the furnace door side sealing cradle and the inner side of the furnace door upper sealing cradle, so that the insulation effect is good. By means of the furnace door self-sealing device for the small and medium size bogie-hearth resistance furnace, the automatic sealing effect can be achieved, the automation level of the modern manufacturing industry is improved, and the mechanism has the advantages of being simple in structure, capable of effectively preventing the ceramic fibers from being abraded, long in service life, good in insulation effect, easy to maintain and the like.
