Float glass melting furnace with contraction type clarification area

Abstract

The present invention provides a float glass melting furnace with a contraction type clarification zone. The float glass melting furnace comprises a clarification zone and a neck which are sequentially distributed along the front-back direction, the clarification zone comprises a contraction section, the rear end of the contraction section communicates with the front end of the neck, the distance between the two side walls of the contraction section is gradually reduced from front to back, the arch span of the arch of the contraction section is gradually reduced from front to back, the central angle of the arch of the contraction section is a set central angle from front to back, and a rear gable wall is arranged at the rear end of the arch. The float glass melting furnace is long in service life and low in energy consumption, and produced glass is high in quality.

Description

technical field [0001] The invention relates to a float glass melting furnace, in particular to a float glass melting furnace with a shrinking clarification zone. Background technique [0002] After years of development, the structure of the float glass melting furnace has been basically fixed. like figure 1 As shown, the main body of the float glass melting furnace in the prior art mainly includes the melting part, the regenerator, the small furnace, the neck 2, the cooling part and other parts. The melting part is further divided into two parts, the melting zone and the clarification zone. Float glass melting furnaces in the prior art have the following defects: [0003] 1. As the kiln width decreases sharply at the corner from clarification zone 1 to neck 2, the pool wall bricks at this place are severely washed by the glass liquid, which affects the life of the kiln; [0004] 2. There are two dead angles at the end of the clarification zone 1, causing a large amount ...

AI Technical Summary

Problems solved by technology

[0003] 1. As the kiln width decreases sharply at the corner from clarification zone 1 to neck 2, the pool wall bricks at this place are severely washed by the glass liquid, which affects the life of the kiln;

[0004] 2. There are two dead angles at the end of the clarification zone 1, causing a large amount of glass liquid to flow slowly and affecting the quality of the glass;

[0005] 3. The upper space of the clarification zone 1 is relatively large, resulting in a large amount of heat dissipation in the space of the glass melting furnace, which in turn leads to high energy consumption;

[0006] 4. The area of ​​the rear gable 112 is relatively large, causing a large amount of alkali vapor to condense on the rear gable 112, and then fall into the glass liquid, seriously affecting the quality of the glass
