Bottom discharging method and device for glass melting furnace

According to the method, molten glass is contained in a glass melting pool, the bottom of the glass melting pool is provided with a first channel used for guiding out the molten glass, the first channel and a tubular structure form a discharging channel of the molten glass, a first power source supplies power to start a first induction coil so as to heat a discharging pipe, the power of the first power source is adjusted, and the discharging pipe is opened; a second temperature sensor measures the temperature T5 of the auxiliary electrode, when the temperature T5 is smaller than the liquidus temperature TL, a third power source supplies power to the auxiliary electrode and the discharging pipe, the auxiliary electrode and the discharging pipe serve as two electrodes, and the auxiliary electrode and the discharging pipe serve as two electrodes; molten glass in a discharging channel between the two discharging pipes generates joule heat under the action of current, the glass in the discharging pipes is melted a
