Description
Technical Field
The invention relates to the technical field of manufacturing of float glass, in particular to a sealing device for a platinum channel flashboard of electronic display glass.
Background
With the development of electronic display glass, the float process for manufacturing large-format ultrathin glass has become a necessary way. In the traditional float process, after the raw materials are melted in a melting furnace, molten glass flows into a tin bath from a liquid flow channel with a rectangular section for forming; the liquid flowing channel is provided with a flashboard for controlling the flow rate of the glass liquid so as to control the thickness of the flat glass. On the fluid channel, a gap is reserved between the flashboard and the top cover of the fluid channel in order to ensure the activity of the flashboard. In the liquid flow channel, the glass liquid is in a state of not filling the groove, and a sealing mode of the upper surface of the top cover can be adopted, for example, patent application with the patent number of 201510476395.7 and the patent name of a liquid flow channel flashboard sealing device. However, when the molten glass in the liquid flowing channel is in a full groove state, the structure cannot meet the use requirement, and the molten glass can overflow from a gap between the flashboard and the top cover of the transition channel.
In order to improve the product quality, a glass liquid stirring process is specially added before the glass liquid flows into a tin bath forming process, so that the number of bubbles in the glass liquid is reduced, and the uniformity of the glass liquid is improved.
In the stirring process, the stirring device consists of a stirring barrel, a stirring rod, a stirring barrel cover plate, a liquid inlet, a liquid outlet, a liquid discharging port, an electric heater and the like, wherein the stirring barrel and the stirring rod are vertically arranged, and the stirring rod is made of platinum materials and rotates slowly (1-15 rpm) so as to prevent bubbles in refractory materials from penetrating glass liquid and slow down the corrosion of the glass liquid on the wall of the stirring barrel.
The liquid outlet of the platinum channel is of a circular section, the liquid inlet of the tin bath is of a rectangular section, and a transition channel with gradually changed section is additionally arranged between the platinum channel and the tin bath for glass liquid to circulate. When manufacturing large-format ultrathin glass by using a float process, a flashboard is arranged on the transition channel and is used for controlling the flow rate of molten glass. Because of the structure and the pressure of the platinum channel, the liquid outlet and the transition channel of the platinum channel are in a full groove state, glass liquid can overflow from a gap between the flashboard and the top cover of the transition channel, and the upper surface sealing mode is not suitable.
