Detachable optical glass successive melting furnace

Abstract

The invention, which relates to a detachable optical glass successive melting furnace and belongs to the technical field of optical glass melting devices, mainly solves the problem that the present melting furnaces highly lead to the aging of platinum vessels which further results in the damage of the platinum vessels, the blowing out of furnaces and long maintenance time. The detachable optical glass successive melting furnace is characterized by comprising successively connected parts of a fusing-section smelting furnace, a heating-section smelting furnace, a clarification-section smelting furnace, a cooling-section pipeline and a working-section smelting furnace, wherein the fusing-section smelting furnace, the heating-section smelting furnace and the clarification-section smelting furnace are connected by connecting pipes; the fusing-section smelting furnace, the heating-section smelting furnace, the clarification-section smelting furnace and the working-section smelting furnace are all equipped with an independent heating device; and the connection pipelines connecting the fusing-section smelting furnace, the heating-section smelting furnace and the clarification-section smelting furnace and the cooling-section pipeline are all provided with a flow control device. The detachable optical glass successive melting furnace provided by the invention has the summing effect of minimizing the container expansion, reduces the crucible damage, is convenient for maintenance, raises the smelting furnace production efficiency, and is mainly used in optical glass successive melting furnaces which can be split and assembled.

Description

technical field [0001] The invention belongs to the technical field of optical glass melting devices. It specifically relates to a continuous melting furnace for optical glass which is suitable for continuous melting of optical glass and can be disassembled for assembly. Background technique [0002] A common optical glass continuous melting furnace is composed of a melting part 1, a heating part 2, a clarifying part 3, a cooling part 4, and a working part 5, and the working part 5 is provided with a leakage pipe 6. All parts are connected through corresponding pipes to complete the flow of glass from the melting part to the working part in sequence. During the flow process, glass defects such as bubbles and streaks in the molten glass are gradually removed to obtain high-quality and high-performance optical products. [0003] Since the optical glass is connected to the various parts of the furnace through pipes, the furnace will be deformed due to the expansion effect duri...
