Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
According to a first aspect of the present application, with reference to fig. 1 to 4, there is initially provided a tin bath ventilation device comprising: a main shunt tube 10, a secondary shunt tube 20, and a secondary damper 30. The main shunt pipe 10 is arranged at the lower part of the bottom of the tin bath, and the length of the main shunt pipe extends along the width direction of the tin bath. The plurality of secondary shunt tubes 20 are arranged along the width direction of the tin bath and are respectively communicated with the main shunt tube 10, and each secondary shunt tube 20 is provided with a plurality of air outlets 21 facing the bottom of the tin bath. A secondary air valve 30 for controlling air quantity is arranged at the position where each secondary shunt pipe 20 is communicated with the main shunt pipe 10. The air output of the plurality of secondary manifolds 20 is configured to: in the width direction of the groove bottom, the trend of the air output of the plurality of secondary shunt pipes 20 is consistent with the trend of the temperature of the groove bottom.
Utilize the molten tin bath ventilation unit of this application to when cooling down the molten tin bath tank bottom, the cooling air at first gets into main shunt tubes 10, and secondary blast gate 30 regulates and control the air output that gets into every secondary shunt tubes 20 by main shunt tubes 10 according to the temperature difference of molten tin bath tank bottom, makes the air output variation trend of many secondary shunt tubes 20 unanimous with the temperature variation trend on the tank bottom width direction, guarantees that the temperature is even on the molten tin bath tank bottom width direction.
When the temperature in the width direction is regulated, the opening degree of the secondary air valve 30 corresponding to the secondary shunt pipe 20 is regulated, so that the requirements of different cooling air in the width direction of the bottom of the tin bath can be met in a differentiated mode, the motion temperature field of tin liquid flow in the tin bath can be well matched, and different circulation flows are formed in the tin liquid in the tin bath, so that the purposes of cooling and enabling the temperature in the width direction to be uniform are achieved.
It should be noted that, the bottom outside of the tin bath bottom generally includes a layer of steel shell, and the cooling wind blows to the bottom, also is equivalent to blow to outside steel shell and cool down.
For example, in the width direction, if the temperature at the middle part of the bottom of the tin bath is too high, the temperature at the edge part is lower, the secondary air valve 30 can increase the air output of the secondary shunt pipe 20 at the middle part and decrease the air output of the secondary shunt pipe 20 at the edge part, so that the difference cooling control of different areas at the bottom of the tin bath is realized, the temperature at the bottom of the tin bath in the width direction is uniform, the thickness flattening uniformity of glass in the tin bath is further ensured, and the problem that the edge of the glass is warped can be effectively reduced. Similarly, if any local temperature at the bottom of the tin bath is too high or too low, the air outlet quantity of the secondary shunt pipe 20 in the corresponding area can be adjusted to be larger or smaller through the secondary air valve 30, so as to keep the temperature uniform.
