A glass melting and heating device

Abstract

The invention relates to the technical field of glass melting equipment and discloses a device for melting and uniformly heating glass. The device comprises a melting furnace, wherein the melting furnace is divided into a vibrating chamber and a melting chamber by a first separating plate; a hollow screw post is connected with the top of the vibrating chamber; the upper end of the screw post is penetrated through the top of the melting furnace and is formed into an exhaust duct; a screw pitch on the upper part of the screw post is more than the screw pitch on the lower part; an air vent is formed on the upper part of the screw post; a second separating plate is arranged in the vibrating chamber; the second separating plate is in sliding connection with an inner wall of the vibrating chamber; an air box is formed between the second separating plate and the first separating plate; an air inlet channel is arranged on a side wall of the air box; the lower end of the screw post is penetrated through the second separating plate and is connected with a ring; rotating teeth are arranged on the outer periphery of the ring; a through hole is formed on the first separating plate; a hollow ball is arranged at the upper end of the through hole; an air inlet is formed on the hollow ball; a hollow vibrating sheet which is hinged with the hollow ball is arranged in the melting chamber. The device provided by the invention can balance the temperature of the molten glass and can increase the quality of the molten glass.

Description

Technical field [0001] The invention relates to the technical field of glass melting equipment, in particular to a glass melting soaking device. Background technique [0002] The production process of the glass bottle is mainly to mix the glass raw materials according to the appropriate ratio, put them into the melting furnace for high temperature melting, and then introduce the molten glass into the glass bottle forming mold for blow molding, and finally put the formed glass bottle into Annealing in the annealing furnace eliminates the internal stress of the glass bottle and enhances the hardness of the glass bottle. [0003] Most of the existing glass melting furnaces heat the furnace by installing a heating device below the furnace, and heat and melt the glass raw materials through convection or radiation heat transfer. Because the heating source is below the furnace, during the heating process, the temperature of the lower part of the molten glass is higher, while the temperat...

AI Technical Summary

Problems solved by technology

Since the heating source is below the furnace, during the heating process, the temperature of the lower part of the molten glass is higher, while the temperature of the upper part is lower, which makes the temperature of the molten glass in the furnace uneven, and the concentration of the molten glass is uneven, resulting in the mold being used. During liquid blow molding, because the part with higher temperature in the molten glass flows faster and has better ductility than the part with lower temperature, the thickness of the bottle body is uneven after the glass bottle is formed, or the bottle body cracks and leaks during the blowing process. etc., produce defective products, waste production raw materials and production labor
