AI Technical Summary

Technical Problem

The existing flame furnaces lead to temperature and density differences in glass liquid during the melting of glass raw materials, forming convection, which reduces the homogenization and clarification temperature of glass liquid in the melting tank.

Method used

A glass furnace is designed, including a furnace and a heat recovery device. The furnace is equipped with a feeding area, a heating area, a homogenization area and a cooling area. The feeding platform is used to melt the glass raw materials and slowly flow into the furnace. The baffle and trough are set to avoid splashing, and the flow rate and depth of the glass liquid are controlled.

Benefits of technology

Through the design of the feeding platform, the convection of the glass liquid is avoided, the homogenization and clarification temperature of the glass liquid in the melting tank is increased, the homogenization and clarification capacity of the furnace is enhanced, and energy consumption is reduced.

Abstract

A glass melting furnace for preparing glass bottles relates to the technical field of glass melting furnaces and comprises a melting furnace and a heat recoverer. The smelting furnace is provided with an opening, and the heat recoverer is connected with the opening in a sealed mode. A feeding area, a heating area, a homogenizing area and a cooling area are sequentially arranged in the smelting furnace in the direction of an assembly line, the depth of molten glass in the feeding area, the depth of molten glass in the heating area and the depth of molten glass in the cooling area are the same and are all lower than the depth of molten glass in the homogenizing area, and a feeding port is formed in the side wall of the feeding area of the smelting furnace. A material receiving platform is arranged in the feeding area and matched with the feeding port, and raw materials enter the smelting furnace from the feeding port, are melted on the material receiving platform and then flow into the bottom of the feeding area in the smelting furnace. The material receiving platform is arranged for buffering the added glass raw materials, and the glass raw materials are melted on the material receiving platform and then enter the molten glass in the melting furnace in the form of high-temperature molten glass, so that the condition of convection in the furnace is avoided, and the homogenizing and clarifying temperature of the molten glass in the melting tank is increased.
