Background
The radiant heat of the flame is transferred to the batch materials and molten glass within the glass tank and the flow of the molten glass within the melting tank is the basic principle of melting and homogenizing the tank. All technical measures for forced melting and improving the quality of the glass liquid are to obtain very large heat with the batch, improve the temperature of the glass liquid, strengthen the flow of the glass liquid and make the thermal convection of the glass liquid more reasonable and stable. The bubbling technology of the tank furnace is that gas is blown in from the bottom of the tank furnace near the hot spot to form bubbles, and along with the rising of the bubbles, the surrounding glass liquid flows upwards to form a mechanical circulating flow, and when the mechanical circulating flow is matched with a liquid spring area of the hot spot of the melting tank, the thermal convection system of the glass liquid is strengthened more strongly. When the bubbling process index is reasonable and the operation is normal, the formed intense and stable heat convection increases the heat absorption capacity of the surface glass liquid, and simultaneously promotes the heat transfer between all layers in the glass liquid, so that the overall temperature of the glass liquid is increased; meanwhile, each stage in the glass melting process is effectively guaranteed, and the glass melting can be successfully completed in each area, so that the glass melting quality is fundamentally guaranteed. Practice proves that at present, the bubbling modes of the domestic furnaces can all play roles of forced melting and promoting the uniformity of glass liquid, but the bubbling modes of different furnaces play roles to different degrees. How to make the bubbling technology of the tank furnace achieve better effects on improving the quality of glass liquid, increasing the melting capacity, reducing the energy consumption and the like.
Chinese patent application number CN201921149555.7 discloses an apparatus for producing flexible glass, comprising a continuous tank furnace and a forming tank arranged in sequence; the bottom of the forming tank is provided with a glass liquid outlet for generating glass plate roots, the side wall of the tail end of the continuous tank furnace is provided with a glass liquid discharge hole, and the side wall of the head end of the forming tank is correspondingly provided with a glass liquid inflow hole; the outer surface of the side wall of the tail end of the continuous tank furnace is vertically provided with a dovetail groove guide rail, the outer surface of the side wall of the head end of the forming tank is provided with a dovetail-shaped sliding block matched with the dovetail groove guide rail, and the forming tank is connected to the continuous tank furnace in a sliding manner; lifting mechanisms are symmetrically arranged at the bottom of the forming pond; a glass pair roller machine for drawing glass plate root is arranged below the forming pool.
