[0002] In the production of substrate glass, the furnace is a crucial piece of equipment, and the electrode bricks, as the core component of the furnace, play a decisive role in heating and melting the molten glass. Electrode bricks are typically composed of several small electrodes joined together and connected by reinforcing bars. During long-term operation, the molten glass inside the furnace continuously erodes the electrode bricks.

[0003] As glass electric melting furnaces are used for longer periods, the electrode bricks become increasingly eroded, leading to a continuous decrease in their heating power. Stable heating power is crucial for maintaining the molten glass and ensuring the continuity of the production process; insufficient heating power directly impacts glass quality and production efficiency.

The heating mechanism includes an electrode brick, a support assembly, and a propulsion assembly. A slot is formed on the side of the furnace body, and the electrode brick is slidably disposed in the slot. The support assembly and the propulsion assembly are both fixedly connected to the furnace body, and the support assembly is located at the bottom port of the slot, abutting against the electrode brick.

[0007] According to one embodiment of the present invention, the upper electrode layer includes upper small electrodes, upper electrode connecting steel bars, upper water-cooling plates, and upper electrode layer wiring circuits. The upper small electrodes are arranged in a matrix, and each upper small electrode has an upper through hole on its side.

The lower electrode connecting steel bar is inserted through the lower through hole. The lower water-cooling plate is fixedly installed on the side of the lower small electrode. The lower electrode wiring circuit is electrically connected to the lower small electrode.

[0009] According to one embodiment of this utility model, the propulsion assembly includes a propulsion sleeve, a propulsion bracket, and a propulsion rod. The propulsion sleeve is fixedly connected to the electrode brick, the propulsion bracket is fixedly connected to the furnace body, the propulsion rod is mateably connected to the propulsion bracket, and the propulsion rod is rotatably connected to the propulsion sleeve.

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0025] like Figures 1 to 5As shown, an electrode brick structure for a substrate glass melting furnace includes a furnace body 1 and an oxy-fuel combustion system. The oxy-fuel combustion system includes an oxygen supply mechanism for supplying oxygen to the furnace body 1 and a heating mechanism 2 for heating the furnace body 1. The heating mechanism 2 includes an electrode brick 3, a support assembly 4, and a propulsion assembly 5. A slot 6 is provided on the side of the furnace body 1. The electrode brick 3 is slidably disposed in the slot 6. The support assembly 4 and the propulsion assembly 5 are both fixedly connected to the furnace body 1. The support assembly 4 is located at the bottom port of the slot 6 and abuts against the electrode brick 3. The propulsion assembly 5 is used to push the electrode brick 3 to slide in the slot 6.

[0026] The electrode brick 3 includes an upper electrode layer 7 and a lower electrode layer 8, which are arranged longitudinally in the slot 6. The upper electrode layer 7 is located above the lower electrode layer 8, and the lower electrode layer 8 abuts against the support component 4. The upper electrode layer 7 includes upper small electrodes 9, upper electrode connecting steel bars 10, upper water-cooling plate 11, and upper electrode layer wiring circuit 12. Several upper small electrodes 9 are arranged in a matrix. Each upper small electrode 9 has an upper through hole 13 on its side. The upper electrode connecting steel bars 10 are inserted through the upper through hole 13. The upper water-cooling plate 11 is fixedly installed on the side of the upper small electrode 9. The upper electrode layer wiring circuit 12 is electrically connected to the upper small electrode 9. The lower electrode layer 8 includes a lower small electrode 14, a lower electrode connecting steel bar 15, a lower water-cooling plate 16, and a lower electrode wiring circuit 17. The lower small electrodes 14 are arranged in a matrix, and each lower small electrode 14 has a lower through hole 18 on its side. The lower electrode connecting steel bar 15 is inserted through the lower through hole 18. The lower water-cooling plate 16 is fixedly installed on the side of the lower small electrode 14. The lower electrode wiring circuit 17 is electrically connected to the lower small electrode 14.

[0027] During the operation of the substrate glass melting furnace, the oxygen supply mechanism provides sufficient combustion gas to the heating mechanism 2. After the electrode bricks 3 in the heating mechanism 2 are energized, the upper small electrode 9 and the lower small electrode 14 are connected to the power supply through their respective electrode wiring circuits. They utilize the principle of heat generation through resistance to heat the furnace body 1, bringing the molten glass to the required melting temperature. As the molten glass erodes the electrode bricks 3, the heating power of the electrode bricks 3 decreases. At this time, the propulsion component 5 pushes the electrode bricks 3 to slide within the slot 6, allowing the electrode bricks 3 to continue to penetrate deeper into the furnace, maintaining good contact with the molten glass and ensuring sufficient applied power. The support component 4 provides support below the electrode bricks 3, ensuring their smooth movement.

[0028] By setting the propulsion component 5, when the electrode brick 3's heating power decreases due to erosion, the electrode brick 3 can be further pushed into the furnace to maintain effective contact with the molten glass, continuously provide sufficient heating power, ensure the stable operation of the glass furnace, and avoid affecting the quality and efficiency of glass production due to insufficient power.

[0029] The electrode brick 3 consists of an upper electrode layer 7 and a lower electrode layer 8, both of which are arranged in a matrix of small electrodes and fixed by connecting steel bars. This structure enhances the overall strength and stability of the electrode brick 3. Meanwhile, the upper water-cooling plate 11 and the lower water-cooling plate 16 cool the upper electrode layer 7 and the lower electrode layer 8 respectively, reducing the operating temperature of the electrode brick 3, decreasing the erosion rate caused by high temperatures, and thus extending the service life of the electrode brick 3.

[0030] The matrix arrangement of the upper small electrode 9 and the lower small electrode 14 makes the heating area more extensive and uniform, which can effectively improve the uniformity of the glass melt heating, which is conducive to improving the melting quality of the glass and reducing defects caused by uneven heating inside the glass.

[0031] According to one embodiment of this utility model, the propulsion assembly 5 includes a propulsion sleeve 19, a propulsion bracket 20, and a propulsion rod 21. The propulsion sleeve 19 is fixedly connected to the electrode brick 3, the propulsion bracket 20 is fixedly connected to the furnace body 1, the propulsion rod 21 is mated with the propulsion bracket 20, and the propulsion rod 21 is rotatably mated with the propulsion sleeve 19. The side of the propulsion rod 21 is provided with external threads, and the propulsion bracket 20 has a threaded hole 22 that is threadedly mated with the propulsion rod 21. The propulsion assembly 5 also includes a handwheel 23, which is coaxially fixedly connected to the propulsion rod 21.

[0032] When the handwheel 23 is turned, it drives the push rod 21 to rotate coaxially. Since the push support 20 is fixed to the furnace body 1, the push rod 21 moves axially under the action of the thread. The push sleeve 19 is fixedly connected to the electrode brick 3. The movement of the push rod 21 pushes the push sleeve 19, thereby driving the electrode brick 3 to slide in the slot 6, realizing the advancement of the electrode brick 3.

[0033] According to one embodiment of the present invention, the heating mechanism 2 includes a protective cover 24, a cover plate 25 and a handle 26. The protective cover 24 is fixedly connected to the furnace body 1, and the electrode brick 3, the support assembly 4 and the propulsion assembly 5 are all located inside the protective cover 24. The cover plate 25 is hinged to the side of the protective cover 24, and the handle 26 is fixedly connected to the cover plate 25.

[0034] When maintenance or repair of internal components is required, simply pull handle 26 to open cover 25; during normal operation, close cover 25 to ensure the internal components are in a relatively enclosed and safe environment. The protective cover 24 prevents operators from accidentally coming into contact with high-temperature, electrically charged components such as electrode bricks 3, ensuring personnel safety. At the same time, cover 25 and handle 26 facilitate daily maintenance and repair work, improving the maintainability of the equipment.

[0035] According to one embodiment of the present invention, the support assembly 4 includes a support frame 27 and a rotating roller 28. The support frame 27 is fixedly connected to the furnace body 1. The support frame 27 has a rotating groove 29. Several rotating rollers 28 are arranged horizontally and rotated in the rotating groove 29.

[0036] During the advancement of electrode brick 3, the gravity of electrode brick 3 acts on rotating roller 28. Rotating roller 28 rotates around its own axis under the frictional force of electrode brick 3, providing rolling support for the advancement of electrode brick 3. The arrangement of rotating roller 28 transforms the sliding friction between electrode brick 3 and support frame 27 into rolling friction, greatly reducing the frictional force during electrode brick 3 advancement, making the advancement of electrode brick 3 smoother, reducing wear on electrode brick 3 and support assembly 4 during advancement, and extending the service life of the equipment. Simultaneously, the transverse arrangement of multiple rotating rollers 28 can evenly support electrode brick 3, ensuring the stability of electrode brick 3 during advancement.

[0037] According to one embodiment of the present invention, the oxygen supply mechanism includes an oxygen generator and a conveying pipe. An air inlet 30 is provided on the top of the furnace body 1. One end of the conveying pipe is connected to the oxygen generator, and the other end of the conveying pipe is connected to the air inlet 30.

[0038] The oxygen generator produces high-purity oxygen, which is delivered to the air inlet 30 at the top of the furnace body 1 through a pipeline. The oxygen enters the furnace through the air inlet 30, allowing for more complete combustion, increasing flame temperature, and enhancing the heating efficiency of the glass melting furnace. This helps improve the melting quality and production efficiency of the glass. Simultaneously, it reduces the emission of pollutants such as nitrogen oxides from combustion products, resulting in significant environmental benefits.

[0039] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
