The invention relates to an emergency
discharge device for a roughening furnace and a
discharge method. According to the device, an overturning device is arranged at a position which is connected with an outlet end of a
heating furnace; when in a normal working state, the device is used as a transition roll table; in an emergency
discharge state, the device is started; according to the principle, normal temperature production water with a certain pressure is sprayed to the surface of hot glass discharged from the furnace under the
emergency condition; when meeting water, the hot glass can be quenched and broken, at the moment, the broken glass is still a
whole body, the glass continues moving forwards along the roll table and collides with a baffle arranged on the device, then the glass is thoroughly broken into fragments under the effect of an
impact force, and the fragments are scattered in a broken glass collecting trolley. The hot glass which is discharged from the furnace under the
emergency condition can be impacted and broken automatically, manual glass breaking operation is replaced, workers are prevented from acting with
confusion when the hot glass is discharged from the furnace under the
emergency condition, the glass is prevented from being adhered to the furnace, the labor is saved, and the efficiency is improved.
