Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the embodiment of the present invention.It should be understood that this
Locate described specific embodiment and be merely to illustrate and explain the present invention embodiment, is not intended to restrict the invention embodiment.
Fig. 1 is the structural schematic diagram of glass furnace provided in an embodiment of the present invention.As shown in Figure 1, shown glass furnace packet
Include: melting tank 1 and clarifying basin 2 are connected between the melting tank and clarifying basin by dog-hole LYD, arrow direction in Fig. 1
For the flow direction of glass metal, i.e. the glass metal of molten state flows into clarifying basin 2 by dog-hole LYD from melting tank 1.Fusing
One end opposite with dog-hole LYD is provided with feed opening in pond 1, and raw material is admitted to melting tank by the feed opening, by being located at
The first heating module heat effect in melting tank 1, the raw material is fused into glass metal in melting tank 1, clear in raw material
Clear agent starts to react, and the gas released starts to polymerize with the bubble in the glass metal of fusing, glass metal by dog-hole into
When entering clarifying basin, torrent collision occurs in dog-hole LYD and largely gathers for bubble in the gas and glass metal that clarifying agent releases
It closes, minute bubbles quickly become air pocket.Under the action of the second heating module being located in clarifying basin 2, bubble is gradually discharged
Glass metal, to realize the purpose of fining glass liquid.
