Embodiment Construction
[0015] like figure 1 and 2 As shown, a wide-body melting furnace for the production of electronic display glass includes a melting furnace 1 whose width is twice that of the original melting furnace. twice the size of the kiln.
[0016] In the melting furnace 1, the melting furnace is divided into a feeding part 1a, a melting part 1b and a clarification part 1c along the raw material flow direction, and one end of the clarification part 1c is connected to the subsequent process. The parapet walls on both sides of the melting part 1b are provided with smoke outlets 1d, and a group of first oxygen-enriched gas guns 1e is perforated on the pool wall below each smoke outlet 1d. There are two rows of oxygen-enriched gas guns 1e, which are symmetrically distributed on the pool walls on both sides of the melting furnace. A group of first heating electrodes 2 are arranged on the pool walls below the first oxygen-enriched gas guns 1e. The electrodes 2 are divided into two rows, symm...

The invention provides a wide-body melting furnace for the production of electronic display glass, which includes a melting furnace (1), and the melting furnace (1) is divided into a feeding part (1a), a melting part (1b) and a The clarifying part (1c) is symmetrically provided with a group of first heating electrodes (2) on the pool wall of the melting part (1b), and also symmetrically provided with a group of first oxygen-enriched gas guns (1e), which are characterized in that: An opening (3) is provided on the pool bottom of the part (1b), and a cover (4) covering the opening (3) is provided in the melting part (1b), and the cover (4) and the opening 3 A cavity (4c) communicating with the outside is formed. On the cover (4), a set of second heating electrodes (5) corresponding to the distribution of the first heating electrodes (2) is provided, and a set of second oxygen-enriched Gas gun (6). The invention has simple structure and convenient refitting, and increases the capacity of the melting furnace by increasing the width of the melting furnace without changing the heating process condition.
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...
