Glass electric melting furnace

Abstract

The invention relates to a glass electric melting furnace. A plurality of electrodes are arranged in a melting tank which is internally provided with temperature-measuring points and communicated with a clarifying tank, a plurality of carbon rods are arranged in the clarifying tank, a platinum forehearth is arranged at one end of the clarifying tank and communicated with a homogenizing platinum pot, and an uptake flue and a liquid flowing hole are arranged between the melting tank and the clarifying tank. Electric energy is fully utilized by the optimized arrangement of molybdenum electrodes,therefore, the energy consumption is greatly decreased and the energy consumption reaches smaller than 2 KWH / kg after improvement; impurities are effectively separated and the requirements on a clarifying process is met by arranging the uptake flue, the liquid flowing hole and the clarifying tank with steps; the requirements on a homogenizing process is met by arranging the homogenizing platinum pot internally provided with a platinum stirrer; and the energy consumption is effectively decreased and the clarification and homogenization qualities are improved by using a plurality of carbon rodswhich are evenly arranged above the clarifying tank as insulated electrodes.

Description

technical field [0001] The invention relates to an electric melting furnace, in particular to a glass electric melting furnace used for glass production. Background technique [0002] In the existing glass furnaces, gas and electric melting are generally used. The gas used has a low calorific value, which makes it easy for impurities to enter the glass products, and the control of emissions in the later stage is more troublesome. The quality control of the electric melting furnace is relatively easy, but the energy consumption is high, generally reaching 2.5KWH / kg, and the process requirements for clarification and homogenization are difficult to meet. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a glass electric melting furnace, which can reduce energy consumption and easily meet the technical requirements of clarification and homogenization. [0004] In order to solve the above technical problems, the techn...

Problems solved by technology

[0002] In the existing glass furnaces, two methods of gas and electric melting are generally used. The gas used has a lower calorific value, which makes it easy for impurities to enter the glass products, and the control of emissions in the later stage is more troublesome.

The quality control of the electric melting furnace is relatively easy, but the energy consumption is high, generally reaching 2.5KWH / kg, and the process requirements for clarification and homogenization are difficult to meet
