Discharge device of glass melting furnace and method thereof

Abstract

The invention discloses a discharge device of a glass melting furnace and a method thereof. The device comprises a siphon pipe, a connecting pipe and an evacuating device, wherein the siphon pipe spans the furnace wall above the glass melting furnace; a liquid inlet end of the siphon pipe is immersed below a liquid level of glass melt in the glass melting furnace, while a liquid outlet end is positioned outside the glass melting furnace in the using process; the horizontal position of the liquid outlet end is lower than that of the liquid inlet end; the liquid outlet end is communicated with the evacuating device through the connecting pipe; and the connecting pipe is melted and disconnected with the liquid outlet end when the high temperature glass melt flows in the connecting pipe. The discharge device ensures that the glass melt is discharged from the top of the glass melting furnace by utilizing a siphon principle, and only needs replacing a connecting pipe with low price in the continuous operation each time; the siphon pipe cannot be subjected to the erosion-corrosion of the glass melt to prolong the service life, so the production cost is reduced; and the discharge device is positioned on the top of the glass melting furnace and completes the discharge process in the siphon mode, so the leakage of the glass melt can be avoided.

Description

technical field [0001] The invention relates to the field of glass melting furnace manufacturing, in particular to a glass melting furnace discharge device and method. Background technique [0002] The glass melting process can be divided into electric heating melting technology and oil gas combustion heating melting technology. Flexible, the most advanced glass melting technology at present. [0003] At present, low-melting glass is being widely used, and the requirements for its output have increased significantly. When preparing low-melting point glass, the melting temperature is required to be high, and it contains more highly corrosive elements. Because metal element oxide materials with low melting point and non-metal element oxide materials with low melting point, such as lead oxide, phosphorus pentoxide, etc., are usually more corrosive at high temperatures exceeding 1000 degrees Celsius, so electric heating and melting When manufacturing glass with a high content...
