Fully electric melting kiln for glass bottle materials

Abstract

The invention relates to an electric kiln, and particularly relates to a fully electric melting kiln capable of melting glass bottle materials electrically. A kiln body is a vertical kiln, and the plane of the kiln body is hexagonal; six molybdenum electrodes at each layer are fixed on six corners of the kiln body in a shape like a Chinese character 'mi'; the molybdenum electrodes are in four layers up and down, and are supplied with power by a power supply system composed of three groups of three-phase transformers and two groups of single-phase transformers, and the power of supplied power and the power supplying modes can be adjusted. A low energy region at the middle part of the plane and the vertical surface of the fully electric melting kiln is changed into a high energy region, and the heat degree in the kiln body is uniform, air bubbles are few, stones cannot be formed, so that the fully electric melting kiln can be used for producing glass bottles and high-level glass liquid materials with high content of silicon dioxide and aluminum oxide; the material liquid product is high in quality, and is high in yield; the fully electric melting kiln is high in heat efficiency of the kiln body, is short in kiln-stopping overhauling time, is high in furnace temperature fluctuation adaptability, and saves electric energy.

Description

technical field [0001] The invention relates to an electric kiln, in particular to an all-electric melting kiln for glass bottle material. Background technique [0002] Compared with oil and gas furnaces, the use of electric melting furnaces to melt glass is an important way to increase production, reduce energy consumption and reduce smoke pollution. At room temperature, glass is an insulator, but after heating, the glass becomes a conductor after melting. Glass electrofusion is to introduce current into the glass liquid through electrodes, and the glass liquid between the two electrodes is generated under the action of alternating current after electrification. Heat Joule, so as to achieve the purpose of melting the glass and adjusting the temperature of the glass liquid. [0003] Depending on the chemical composition, there are many types of glass, such as high volatile component glass and dark colored glass. According to the different needs of life, there are many type...

Problems solved by technology

[0006] Therefore, the quality of molten glass produced by this traditional all-electric melting furnace is poor and the defective rate is high. The defective rate of glass bottles made of this kind of molten glass can reach 80%-90%. The kiln is also prone to stone formation, which shortens the life of the kiln body

At the same time, the fluctuation of kiln body charging is poor. If the design is designed to discharge 15T every 24 hours, it can only maintain the normal use of the electric melting kiln for about one year, and the difference can only be guaranteed to be ±3%. Once the power failure stops, it will take 16 hours to resume production -48 hours
