APPARATUS FOR EXHAUSTING EXPLOSIVE GAS IN THE ANNEALING FURNACE

摘要

The present invention due to the abnormal operation of the inside of the annealing detect its pressure is issued if the small explosions and relates to an automatic door release device for an explosion of the internal pressure induced by annealing in order to prevent the equipment accident led to a large explosion, by automatically opening the exit door, at the discharge side of the upper end of the annealing furnace 1, in the annealing (1) and a cylindrical port (60) formed therethrough; Is built into the unit casing 25 is formed in a disk-shaped outer pressure absorbing plate 26 and fixed to the lower end of the annealing furnace 1, that is through-absorbing plate to the vertical axis 28 of the cylindrical port 60; As the absorbing plate rack gear formed on the vertical axis (28) (27) and coarse pinion gear gear coupling 40 is fixed to the center, one side of the fixed and the other side a horizontal bevel gear 29 is a driven pinion gear (33) a fixed horizontal rotation bar 30 and; The horizontal bevel gear 29 and bevel gear coupling the vertical gear 22 is fixed to the upper end of the combined rotary shaft 21 round the opening and closing door to open and close the cylinder port 60, 20, and; That the driven pinion gear 33 and the gear rack guide coupling gear (41a) is fixed to the formed guides (41) constituted by a sliding vertical shaft 34 is installed so as to project to one side upper surface of the unit case 25, provides an automatic door system for the explosion pressure inside the annealing induced emissions of claim.
