Embodiment

[0073] At the same time, three groups of experiments were carried out to verify the cooling effect of the continuous pushing type molybdenum electrode cooling water jacket of the present invention and the performance of different working modes. Figure 7 to Figure 9 are the structural schematic diagrams of the devices used in the three groups of experiments, which are only used for illustration purposes. Figure 7 The reference molybdenum electrode cooling water jacket used in the first group of experiments but did not draw its internal structure in detail, Figure 8 with Figure 9 The part from the middle plate to the tail plate of the molybdenum electrode cooling water jacket is not drawn.

[0074] The first group uses the molybdenum electrode cooling water jacket (model EH-15-2"-1600) produced by Horn Glass Industries.

[0075]The second group adopts the continuous push-type molybdenum electrode cooling water jacket described in the present invention, and is in the normal...

Abstract

The invention relates to a continuously pushable molybdenum electrode cooling water jacket, which comprises an outer tube, an annular end plate, an annular tail plate and an annular middle plate; Pipe, air outlet pipe; in the area between the end plate and the middle plate, a hollow cylindrical partition and a hollow cylindrical intermediate shaft are arranged inside the outer tube, and the outer tube, partition and intermediate shaft are all from the outside to the inside Coaxial setting; the outer wall of the intermediate shaft is provided with a spiral cooling channel, and the spiral cooling channel is integrally formed with the intermediate shaft; an air compartment is formed between the partition plate and the outer tube, and an end plate is provided between the end plate and the intermediate shaft Cooling water channel, the water inlet of the end plate cooling water channel is connected with the water outlet of the cooling water channel, and the water outlet of the end plate cooling water channel is connected with the water inlet of the water outlet pipe; a thermocouple for detecting the temperature of the end plate is also installed inside the air compartment. The invention has the advantages of good heat transfer, small deformation, corrosion resistance, long-term reliable operation and the like.

Description

technical field [0001] The invention relates to a cooling device, in particular to a molybdenum electrode cooling water jacket of a push-on type electric melting equipment. Background technique [0002] Glass in the molten state conducts electricity. The so-called glass electrofusion means that the current is introduced into the molten glass through the electrodes. After the electricity is applied, the molten glass between the electrodes generates Joule heat under the action of alternating current, so as to achieve the purpose of melting and temperature adjustment. Electric boosting refers to the application of glass electric melting as an auxiliary heating method in a glass tank furnace heated by traditional fuels (natural gas, heavy oil and petroleum coke powder, etc.). Generally, electric boosting is used to melt 10%-40% of the molten glass in the glass tank furnace. [0003] Electrode materials commonly used for glass electrofusion include graphite, molybdenum and tin ...
