Electric melting crucible kiln for drawing flexible glass

Abstract

The invention discloses an electric melting crucible kiln for flexible glass, and belongs to the technical field of melting furnaces. The electric melting crucible kiln comprises a kiln body; the kilnbody comprises a melting chamber, a clarifying chamber and a forming chamber which sequentially communicate with one another from front to back; a feeding port and an observation hole are formed in the upper end of the melting chamber; a discharging groove is formed in the lower end of the forming chamber; a temperature detection device and a heating device are arranged in each of the melting chamber, the clarifying chamber and the forming chamber, and a liquid flowing channel communicating the melting chamber with the clarifying chamber is arranged between the melting chamber and the clarifying chamber; a cooling channel is arranged above the liquid flow channel; a second thermocouple is arranged at the bottom of the liquid flow channel; an airflow isolation device is arranged between the clarifying chamber and the forming chamber. The temperature of molten glass is controllable and adjustable, conditions are created for drawing the flexible glass, the quality of the drawn flexible glass is guaranteed, resource saving is facilitated, efficient utilization of energy is achieved, and the electric melting crucible kiln has good practical value.

Description

technical field [0001] The invention belongs to the technical field of melting furnaces, and relates to a crucible furnace for manufacturing flexible glass, in particular to an electric melting crucible furnace for drawing flexible glass. Background technique [0002] Glass melting furnace is a kind of main thermal melting equipment for manufacturing glass. The design structure of glass furnace directly affects the glass forming and plays a key role in the quality of glass manufacturing. At the same time, the quality of the furnace also has an impact on the environment. Impact. The flexible glass itself is very thin and has good flexibility, which makes the flexible glass have very high requirements on the furnace during the melting stage. The existing flexible glass electric melting furnaces will have uneven glass temperature and large fluctuations in glass temperature during operation, which leads to unstable speed, uneven thickness, bubbles, etc. during the drawing proce...
