Abstract

The invention belongs to the technical field of substrate glass manufacturing, and particularly discloses a platinum channel feeding top heating device which comprises a heat preservation cylinder, a top heater and a bottom heater which are connected in sequence from top to bottom, a liquid inlet hole is formed in the heat preservation cylinder, and an upper heating channel is formed in the top heater. The upper heating channel comprises a straight hole heating section and a taper hole heating section, and a lower heating channel is formed in the bottom heater; the straight hole heating section is communicated with a liquid inlet hole, and the taper hole heating section is communicated with the lower heating channel; a liquid level pipe for storing molten glass is arranged in the lower heating channel; and a plurality of heating grooves for winding heating wires are formed in the inner walls of the straight hole heating section, the taper hole heating section and the lower heating channel. According to the heating device, the liquid level in the liquid level pipe can be effectively heated, so that the viscosity of the liquid level pipe is close to that of internal glass fluid, the liquid level pipe participates in normal operation of a flow field environment, and formation of heterogeneous glass with increased viscosity is eliminated from the source.

Description

technical field [0001] The invention belongs to the technical field of substrate glass manufacturing and relates to a heating device for a platinum channel feeding top. Background technique [0002] The platinum channel plays an important role in the manufacturing process of the substrate glass. Due to the differences in the functional principles of different regions, the state of the designed molten glass inside the channel is also different, including the characteristics of the liquid surface, such as clarification. Due to the high-temperature clarification and bubble removal treatment of the molten glass, it is necessary to design a space above the liquid surface in the pipeline for the escape of bubbles; and there is also a liquid surface in the stirring tank area, which needs to be inserted A stirrer is used to achieve the homogenization of the glass liquid; in addition, there is another type that considers that the liquid level of the system needs to meet the connector...
