Tin bath ventilation device, tin bath cooling system and tin bath

Abstract

The invention provides a tin bath ventilation device, a tin bath cooling system and a tin bath. The tin bath ventilation device comprises a main shunting pipe, a plurality of secondary shunting pipes, a secondary air valve and the like. The main shunting pipe is arranged at the bottom of the tin bath, the length of the main shunting pipe extends along the width direction of the tin bath. The multiple secondary shunting pipes are arranged in the width direction of the tin bath and communicate with the main shunting pipe, and each secondary shunting pipe is provided with a plurality of air outlet holes facing the bottom of the tin bath. The secondary air valve for controlling the air volume is arranged at the communication part of each secondary shunting pipe and the main shunting pipe. The air outlet amount of the multiple secondary shunting pipes is configured in the mode that in the width direction of the groove bottom, the change trend of the air outlet amount of the multiple secondary shunting pipes is consistent with the temperature change trend of the groove bottom. According to the technical scheme, it is effectively guaranteed that the temperature in the width direction of the tin bath bottom is uniform.

Description

technical field [0001] The present application relates to the technical field of glass manufacturing, in particular to a tin bath ventilation device, a tin bath cooling system and a tin bath. Background technique [0002] As one of the three thermal equipments in float glass manufacturing, tin bath is the core equipment for glass forming. In float glass manufacturing, how to protect the safe operation of tin bath is very important. Due to the high temperature of the tin liquid in the tin bath, the high-temperature tin liquid penetrates into the bottom plate through the gaps between the bricks, which is very corrosive to the bottom plate and the bolts welded on the bottom plate, and poses a huge threat to the safety of the tin channel steel structure. After tinning, the bottom plate must be cooled continuously to ensure normal production. [0003] Because the temperature at the edge of the bottom of the tin bath loses relatively quickly, the temperature at the edge of the bo...

AI Technical Summary

Problems solved by technology

[0003] Due to the relatively fast loss of temperature at the edge of the tin bath bottom plate, the temperature at the edge of the tin bath bottom plate is lower than that in the center, resulting in uneven temperature in the width direction of the tin bath bottom plate

The uneven temperature in the width direction of the bottom plate of the tin bath may cause the thickness of the middle and edge of the glass to be inconsistent, and may also warp the edge of the glass, affecting the quality of the glass

In the existing technology, the overall air cooling method is often used for cooling, which cannot solve the problem of uneven temperature
