Description
Technical Field
The utility model relates to the technical field of float plate glass production, in particular to a novel float tin bath outlet baffle curtain combined structure.
Background
The float tin bath is a thermal equipment for forming float plate glass, after molten glass enters the tin bath, forming processes of flattening, polishing, drawing Bao Huo thick and the like are completed on the molten glass surface to form a continuous glass strip, the glass strip enters an annealing kiln for annealing treatment through a tin bath outlet, and finally, the glass is optimally cut to form finished plate glass after reaching a cold end.
In the tin bath, glass floats on the molten tin, if the pressure of the protective atmosphere of the tin bath is low, oxygen easily permeates into the tin bath, and the molten tin is easily oxidized to generate tin oxide and has influence on the quality of the glass plate. In order to ensure the working condition of the tin bath, a reducing protective gas for preventing the oxidation of the tin liquid needs to be continuously introduced into the tin bath. In order to provide sufficient pressure for the reducing shield gas inside the tin bath to prevent oxygen outside the tin bath from penetrating into the tin bath and oxidizing the tin bath, it is necessary to seal the entire tin bath. Since the molten tin bath outlet is always drawn with a continuous glass ribbon, a certain amount of glass sheet passing space must be reserved, so the molten tin bath outlet also becomes a place where the molten tin bath protective gas flows out most, and if a large amount of protective gas escapes from the molten tin bath outlet along with the drawn glass, the molten tin bath pressure, the molten tin bath working condition and the quality of the glass ribbon are greatly influenced, so that the problem of sealing the molten tin bath outlet is particularly important.
Currently, several tin bath outlet baffles are installed above a tin bath outlet transition roller table in the float glass industry to form a tin bath outlet sealing structure. Most of the existing tin bath outlet blocking curtains are soft blocking curtains with all-metal material blocking curtains or glass fiber cloth as main bodies, and the blocking curtains have the following defects: the shielding curtain is made of a metal plate, after installation, the temperature difference exists in the space height of the outlet of the tin bath, the metal is heated unevenly and deformed seriously, the shielding curtain forms a bow shape with high two sides and low middle, and the shielding curtain forms a wave bend in the longitudinal direction, so that the sealing performance of the outlet of the tin bath is poor; if the height of the metal baffle is reduced for improving the sealing, the lower part in the middle of the baffle is easy to scrape against the glass plate to scratch the upper surface of the glass plate, and when the quality problem of scratch of the glass is found in cold end inspection, the glass of the whole annealing kiln is required to be scrapped, so that great loss is caused. And secondly, the soft curtain using the glass fiber cloth as a main body structure is easy to blow open by tin bath airflow due to the influence of tin bath pressure because the glass fiber cloth is light in weight, and cannot be sealed well.
