Embodiment Construction
[0018] like Figure 1-4 As shown, a double melting part wide body melting furnace for electronic display glass production includes a melting furnace 1, the width of the melting furnace 1 is twice that of the original melting furnace, that is, the melting area of the melting furnace 1 Twice as the original melting furnace.
[0019] The furnace 1 is divided into a feeding part 1a, a melting part 1b and a clarification part 1c along the flow direction of the raw material, and one end of the clarification part 1c is connected to the subsequent process. A first dome 1e is bridged over the pool wall of the feeding part 1a, and a second dome 1f is bridged over the pool wall of the clarification part 1c.
[0020] A group of first heating electrodes 2 are symmetrically arranged on the pool wall of the melting part 1 b , and a group of first burners 10 are also arranged symmetrically on the pool wall above the group of first heating electrodes 2 . The set of first heating electrodes...

The invention discloses a double-melting-part wide-body melting furnace for producing electronic display glass. The double-melting-part wide-body melting furnace comprises a melting furnace (1), wherein the interior of a melting furnace (1) is divided into a feeding part (1a), a melting part (1b) and a clarifying part (1c); a group of first heating electrodes (2) and a group of first burners (1e)are symmetrically arranged on the tank wall of the melting part (1b). The double-melting-part wide-body melting furnace is characterized in that an opening (3) is formed in the bottom of the melting part (1b), a corresponding enclosure wall (4) is arranged on the opening (3), second heating electrodes (5) correspondingly matched with the first heating electrodes (2) and second combustors (6) corresponding to the first combustors (1e) are arranged on the enclosure wall (4); and a third arch top (7) is bridged between the enclosure wall (4) and the melting part (1b). The disclosed melting furnace is simple in structure and convenient to use, the capacity of the melting furnace is improved under the condition that the heating process is not changed, maintenance is convenient, and surplus heatin the cavity is convenient to dissipate.
Description
Technical field: [0001] The invention relates to the field of electronic display glass production, in particular to a double-melting part wide-body melting furnace for electronic display glass production. Background technique: [0002] In the field of electronic display glass (TFT-LCD glass) manufacturing, the melting furnace consists of a feeding part, a melting part, a clarifying part and other parts. The vertical cross-section includes the bottom of the pool, the pool wall, the parapet, and the top. The parapet is equipped with smoke exhaust The mouth, the pool bottom and the pool wall need to be air-cooled. The pool bottom and pool wall are used to hold the glass melt. The upper space is between the glass melt plane and the top of the feeding part, and between the glass melt plane and the top of the melting part. For the combustion space, the whole furnace is suspended and fixed. In order to meet the process requirements, the melting temperature of the molten glass is a...
