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 and 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...

The invention relates to a continuous push type molybdenum electrode cooling water jacket, which includes an outer tube, an annular end plate, an annular tail plate and an annular intermediate plate. The inside of the outer tube is provided with a water inlet pipe, a water outlet pipe, an air inlet pipe, and an air outlet pipe. In the space between the end plate and the intermediate plate, the inside of the outer tube is provided with a hollow columnar partition plate and a hollow columnar intermediate shaft, and the outer tube, the partition plate and the intermediate shaft are all coaxially arranged from the outside in. The outer side wall of the intermediate shaft is equipped with a spiral cooling water channel, and the spiral cooling water channel and the intermediate shaft are molded integrally. An air buffer is formed between the partition plate and the outer tube, an end plate cooling water channel is arranged between the end plate and the intermediate shaft. The water inlet of the end plate cooling water channel is connected to the water outlet of the cooling water channel, and the water outlet of the end plate cooling water channel is connected to the water inlet of the water outlet pipe. The air buffer is also internally provided with a thermocouple detecting the end plate temperature. The continuous push type molybdenum electrode cooling water jacket provided by the invention has the advantages of good heat transfer, small deformation, corrosion resistance and long-term reliable operation, etc.
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 ...
