Abstract

The invention discloses an indirect cooling and direct cooling combined electrode water jacket, which belongs to the technical fields of glass melting devices and inorganic material high-temperature electric melting technologies and mainly solves the problem that the conventional direct cooling type or indirect cooling type molybdenum electrode protection device cannot protect a molybdenum electrode well. The indirect cooling and direct cooling combined electrode water jacket is mainly characterized by comprising a water jacket shell, and a direct cooling water jacket water inlet pipe, a direct cooling water jacket water outlet pipe, a direct cooling water collector, a direct cooling water jacket water baffle and a temperature measuring device which are arranged in the water jacket shell, wherein the direct cooling water jacket water inlet pipe is provided with spray holes; the inner side part of the water jacket shell is provided with a closed indirect cooling cavity, an indirect cooling water jacket water outlet and an indirect cooling water jacket water inlet pipe; the closed indirect cooling cavity is formed by an indirect cooling cavity rear baffle, an indirect cooling cavity front baffle, an indirect cooling cavity inner wall pipe and the water jacket shell; and the indirect cooling water jacket water outlet and the indirect cooling water jacket water inlet pipe are connected with the indirect cooling cavity. The indirect cooling and direct cooling combined electrode water jacket has the characteristics of effectively protecting the molybdenum electrode, reducing oxidation of the molybdenum electrode, cooling the wall of a melting furnace and prolonging the service life of the melting furnace, and is mainly used for optical glass melting furnaces or other electrode protection water jackets of electrodes, heated by the molybdenum electrode.

Description

technical field [0001] The invention belongs to the technical field of glass melting and high-temperature electrofusion of inorganic materials. Specifically, it relates to a molybdenum electrode protection water jacket which adopts a combination of indirect cooling and direct cooling, which is suitable for molybdenum electrode protection of high temperature melting glass or inorganic materials. Background technique [0002] The all-electric melting technology of glass is more and more widely used, and the matching molybdenum electrode protection technology is becoming more and more important. In a furnace that uses molybdenum electrodes to melt glass, the service life of the molybdenum electrodes directly affects the service life and product quality of the furnace. Improper molybdenum electrode protection technology often causes accidents such as electrode oxidation and fracture. Seriously affect the quality of glass products and increase the cost.

Problems solved by technology

The advantage is that it has a good cooling effect on the furnace wall around the electrode, especially on the front end of the water jacket, which is beneficial to reduce the brick erosion at the electrode hole; the disadvantage is that the cooling effect on the molybdenum electrode is poor, resulting in the molybdenum electrode High temperature and severe oxidation

Often due to the poor cooling effect of the electrode, the protection fails and the molybdenum electrode breaks.
