Description

Technical Field

[0001] The utility model relates to the technical field of glass manufacturing, in particular to a tin bath dispersing device. Background Art

[0002] During the float glass forming process, the stable atmosphere and tank pressure of the tin tank can greatly reduce the contamination of tin liquid, which is crucial to reducing glass forming defects. However, since the glass is easily brought into the tin tank during the melting process, or the oxygen that penetrates when the tin tank is not sealed well, it causes great damage to the atmosphere in the tank, and the impurities such as oxides or sulfides produced will adhere to the tank wall, top cover and tin liquid if they are not removed in time. When the conditions in the tank change, such as the fluctuation of tank pressure or temperature, the accumulated impurities will cause the glass to have forming defects such as dripping or tin staining.

[0003] In the related art, ordinary float glass generally only has 2-3 pairs of diffusers in the high temperature zone and medium temperature zone of the tin bath, while ultra-thin electronic glass has diffusers installed in the high temperature zone and low temperature zone of the tin bath due to the need for molding atmosphere, which can be as many as 10 pairs or more. When all the diffusers are turned on, the pressure and atmosphere of the tin bath are greatly affected. At the same time, the exhaust gas directly discharged by the diffuser in the related art will also pollute the environment. Based on this, the existing technology still needs to be improved.
