Wide-body melting furnace for producing electronic display glass

Abstract

The invention provides a wide-body melting furnace for producing electronic display glass. The wide-body melting furnace comprises a melting furnace (1), the interior of the melting furnace (1) is divided into a feeding part (1a), a melting part (1b) and a clarifying part (1c) in the flowing direction of raw materials; a group of first heating electrodes (2) are symmetrically arranged on the tankwall of the melting part (1b); and a group of first oxygen-enriched gas guns (1e) are also symmetrically arranged on the tank wall of the melting part (1b); the wide-body melting furnace is characterized in that an opening (3) is formed in the bottom of the melting part (1b), a cover body (4) covering the opening (3) is arranged in the melting part (1b), a cavity (4c) communicated with the outsideis formed by the cover body (4) and the opening (3); and a group of second heating electrodes (5) distributed corresponding to the group of first heating electrodes (2) and a group of second oxygen-enriched gas guns (6) are arranged on the cover body (4). The melting furnace is simple in structure and convenient to modify, and the capacity of the melting furnace is improved by increasing the width of the melting furnace without changing heating process conditions.

Description

Technical field: [0001] The invention relates to the field of electronic display glass production, in particular to a wide-body melting furnace for electronic display glass production. Background technique: [0002] In the field of electronic display glass production, the melting furnace is composed of feeding part, melting part, clarifying part and other parts. The upper space above the molten glass and the lower part of the roof is the upper space, and there is a smoke exhaust port on the parapet. [0003] In order to meet the process requirements, the melting temperature of the molten glass is as high as 1680°C. Heaters (oxygen-enriched gas guns, heating electrodes) are used to melt the raw materials. The heaters are symmetrically installed on the wall of the melting furnace. On the surface, the heating electrode is submerged into the molten glass body, and is first heated with an oxygen-enriched gas gun, and then the heating electrode is used to continue heating after t...

AI Technical Summary

Problems solved by technology

There is also technology, in order to increase the melting capacity of the furnace, after increasing the width of the kiln body, a heating electrode is also installed on the bottom of the pool. First, it is difficult to replace the heating electrode due to the pressure of the glass melt; second, the current action path has changed. , the original operating environment is changed
