Technical Field

The invention relates to the technical field of float glass manufacturing, in particular to a float electronic glass tin bath runner transition bath.

Background

When manufacturing float glass, various raw materials are melted at high temperature in a kiln to form molten glass, then the molten glass enters a tin bath, is spread and formed under the drawing of an edge roller, passes through a transition roller table, enters an annealing kiln, and is cooled and annealed. For ordinary float glass, the temperature of the glass liquid entering the tin bath through the narrow flow channel is about 1000 ℃, the viscosity of the glass liquid is low, and the glass liquid is easy to flatten and form in the tin bath.

Electronic glass requires higher thermal stability, high softening point and mechanical strength of glass, and usually alumina is added, the higher the proportion of the alumina is, the higher the melting temperature is, the higher the viscosity is, the melting temperature in a kiln is about 100 ℃ higher than that of common glass, and the forming temperature is also dozens of degrees to more than one hundred degrees higher. After glass liquid enters the tin bath through the flow channel, the glass liquid is easy to accumulate at the entrance of the tin bath, so that the edge roller is difficult to pull, and the glass is difficult to flatten and form in the tin bath due to high viscosity.

In order to facilitate the flattening and forming of the molten glass in the tin bath, the temperature of a high-temperature section of the tin bath is generally raised, on one hand, the energy consumption is increased after the temperature is raised, on the other hand, after the temperature is raised, equipment such as heating equipment and a bath body edge roller needs to use higher-grade materials, the cost investment is increased, the equipment is operated in a high-temperature state for a long time, and the probability of failure is increased.

Disclosure of Invention

The invention aims to provide a float electronic glass tin bath flow channel transition bath which can increase the width of glass liquid entering a tin bath, is convenient for an edge roller to flatten and form, and can heat and regulate the temperature of the glass liquid in the transition bath to stabilize the viscosity of the glass liquid.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a float electronic glass molten tin bath runner transition groove is arranged between a molten glass runner and a molten tin bath, the inlet of the transition groove is connected with the molten glass runner, and the outlet of the transition groove is connected with the molten tin bath; the transition groove comprises an upper groove body and a lower groove body, the lower groove body comprises a refractory brick groove body layer, a lower heat-insulating layer wraps the exterior of the refractory brick groove body layer, and an electric heater is clamped between the refractory brick groove body layer and the lower heat-insulating layer; the upper tank body comprises an upper sealing cover which covers the lower tank body, and an upper heat-insulating layer is arranged on the periphery of the upper sealing cover;

two molten glass width adjusting flashboards are vertically and symmetrically arranged in the transition groove and can horizontally move along the width direction of the transition groove.

Furthermore, a glass liquid flow regulating flashboard is arranged in the glass liquid flow channel.

The beneficial effect of the invention is that,

the transition groove is added, so that the length of the high-temperature section of the tin groove is greatly shortened, or the high-temperature section is almost not existed, the energy consumption is reduced, the service life of equipment is prolonged, and the one-time investment is reduced.

And secondly, the width of the molten glass entering the tin bath is increased, so that the edge roller is convenient to flatten and form.

And thirdly, heating and controlling the temperature of the glass liquid in the transition groove to stabilize the viscosity of the glass liquid entering the tin bath, thereby facilitating stable forming.

Fourthly, the effective width of the transition groove can be adjusted through the glass liquid width adjusting flashboard, and the width of the glass belt can be adjusted conveniently.
