玻璃基板熔炉

Glass substrate smelting furnace

Abstract

本发明公开了一种玻璃基板熔炉,包括熔炉本体(5),所述熔炉本体向前延伸出有预熔池(1),该预熔池的前侧胸墙上对称开设有两个加料口(2),在左右两侧胸墙上分别开设有烧枪口(3),并且在前侧胸墙上方还开设有一个排烟口(4),通过在熔炉本体的前侧上增设预熔池,可以将配合料首先通过烧枪口进行高温预熔,经过加热预熔后的玻璃液流到熔炉本体的熔化池内只需少量的能量就可以明显提高熔化质量,同时由于加料口设置于预熔池的前侧胸墙上,堆积的配合料形成的料山对于熔炉本体的温度影响就会减小甚至被抵消,料山仅在预熔池内波动,不会影响熔炉本体的熔化池的温度,保证工艺稳定性,为产品质量提供一个良好的基础。
The invention discloses a glass substrate smelting furnace which comprises a smelting furnace body (5). The smelting furnace body extends forwards to form a pre-smelting pond (1). Two feed inlets (2) are symmetrically formed in a front breast wall of the pre-smelting pond. A left breast wall and a right breast wall are each provided with a burning lance (3), and a smoke outlet (4) is further formed in the upper portion of the front breast wall. The pre-smelting pond is additionally arranged on the front side of the smelting furnace body, batch can be pre-smelted at high temperature firstly through the burning lances, and heated and pre-smelted liquid glass flows into a smelting pond of the smelting furnace body and only needs little energy to obviously improve smelting quality; meanwhile, the feed inlets are formed in the front breast wall of the pre-smelting pond, temperature influences of a material pile formed by the accumulated batch on the smelting furnace body can be reduced or even eliminated, and the material pile only fluctuates in the pre-smelting pond and does not affect the temperature of the smelting pond of the smelting furnace body. Process stability is guaranteed, and a good foundation is provided for product quality.
