A glass production device

Abstract

The present invention relates to the field of glass manufacturing, and discloses a glass production device. The glass production device includes a feeding device and an overflow tank, and the outlet of the feeding device opens toward a groove of the overflow tank, so The glass solution uniformly distributed along the length direction of the groove of the overflow tank can be injected into the groove of the overflow tank. The glass production device provided by the invention can produce glass with a uniform thickness distribution under the conditions of reducing the processing difficulty of the overflow tank and avoiding the stress of the glass exceeding the standard.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to a glass production device. Background technique [0002] In the production of overflow down-draw flat glass, the glass solution is injected into the L pipe from the feed pipe, and enters the overflow tank from one end of the overflow tank through the L tube. When the glass solution in the overflow tank accumulates to a certain extent, the glass solution flows from The overflow tank overflows along the edge, and flows downward along the outer surface of the overflow tank, gathers and bonds together at the bottom, and then undergoes annealing and other processes to form flat glass. Since the surface of the overflowing glass solution is always in contact with air, the flat glass produced by the overflow down-draw method has a smooth outer surface. [0003] However, in this production process, since the glass solution is injected from one end of the overflow tank, and the glass so...

Problems solved by technology

[0005] Although the above measures can change the thickness distribution of the flat glass, there are still some local problems where the extreme difference exceeds the standard; at the same time, due to the temperature adjustment in the process, the local temperature of the flat glass changes, thus forming inside the finished flat glass. Excessive stress

In terms of equipment adjustment of the overflow tank, in order to solve the problem of thickness, the design of the overflow tank is complicated, which incidentally increases the difficulty of the processing of the overflow tank
