An energy-saving multi-stage leak-board glass kiln device

Abstract

An energy-saving multi-stage drainboard glass kiln device, including a melting chamber, a heat preservation chamber, a shell layer and a temperature control system, characterized in that a first-stage drainboard is installed in the center of the bottom of the melting chamber, and the heat preservation chamber is located at the bottom of the melting chamber Directly below, a secondary leakage plate is installed in the center of the bottom of the heat preservation chamber, and there is a layer of air between the shell layer, the melting chamber and the heat preservation chamber. The beneficial effects of the present invention are: ①Excellent heat preservation effect, energy saving and environmental protection; ②The internal temperature of the kiln is uniform, and the product performance is improved; ③The impurity content in the primary silk is greatly reduced, the primary silk forming rate is increased, and the product performance is more stable.

Description

technical field [0001] The invention relates to a kiln device, in particular to an energy-saving multi-stage drainboard glass kiln device. Background technique [0002] Glass microfiber products play an extremely important role in national life. This kind of glass clinker is used as raw material, melted and drawn, and then flame-blown into cotton-like glass microfibers with an average diameter of 0.5-4μm. It is mainly used for the production of inorganic Raw materials such as high-temperature filter paper, glass fiber separators for lead-acid batteries, and thermal insulation products. With the continuous expansion of the application field of glass microfibers, the quality requirements for glass microfibers in the industry are gradually increasing. However, the current glass microfiber production process often has the disadvantages of a poor silk-forming rate and impurities in the silk. In the production process, it has to be adjusted for a long time to screen out pure silk...

AI Technical Summary

Problems solved by technology

However, the glass liquid inside the kiln of this design is not easy to be completely discharged, and some glass liquid will remain in the kiln at the end, which not only causes waste of raw materials, but also reduces the service life of the kiln.

[0006] The U.S. Patent No. US005613994A provides a furnace body structure, which solves the problem that the refractory materials of the current kiln need to be frequently replaced and overhauled to stop the furnace or stop production, which greatly improves the service life of the kiln and simplifies the process. Furnace maintenance means

However, problems such as impurities in molten glass in the furnace cannot be handled well, resulting in poor glass fiber forming performance and poor fiber quality.

[0007] Most of the existing glass furnaces have problems of low energy utilization rate, uneven temperature of molten glass and a small amount of impurities in the primary filament, resulting in low filament formation rate and unstable product quality.
