Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for glass furnaces, specifically relating to an anti-oxidation and fracture structure for a fluxing electrode. Background Technology

[0002] In addition to directly heating the glass raw materials with high-temperature flames, glass furnaces also need to use fluxing electrodes to achieve electric heating fluxing in order to accelerate glass melting, enhance glass melt convection, and improve glass melt uniformity. This involves inserting rod-shaped fluxing electrodes into the glass melt and using the resistance heat generated when current passes through the electrodes and the glass melt to heat the glass melt, causing it to heat up and melt rapidly.

[0003] The fluxing electrodes used in glass furnaces are mostly molybdenum electrodes, as shown in the instruction manual. Figure 1 As shown, a water-cooled jacket 2 surrounds the molybdenum electrode 1 and is horizontally inserted into the electrode brick holes on the side wall 3 of the glass furnace. The water-cooled jacket is fixedly connected to the side wall of the glass furnace via a flange 4. One end of the molybdenum electrode extends into the furnace to heat the molten glass, while the other end is located outside the furnace for connection to a power source. The water-cooled jacket is used to circulate cooling water to reduce the temperature of the molybdenum electrode, preventing oxidation and corrosion of the portion of the molybdenum electrode located outside the furnace due to high temperature and exposure to an oxygen-rich environment. However, the portion of the molybdenum electrode located inside the furnace is still subject to oxidation and corrosion due to heating requirements. Specifically, before the molybdenum electrode, in conjunction with the glass furnace, heats the glass raw material inside the furnace, causing the glass raw material to melt and form molten glass that submerges the molybdenum electrode inside the furnace, the molybdenum electrode inside the furnace will be briefly exposed to a high-temperature oxygen-rich environment. During this stage, although the molybdenum electrode will undergo some degree of oxidation and corrosion, this will not significantly shorten its service life and is considered normal wear and tear. However, after the molybdenum electrode is submerged in the furnace by molten glass, air bubbles easily form on its surface, especially at the inner end of the electrode brick hole. Because there are gaps between the molybdenum electrode surface and the electrode brick hole at this location, and because the molten glass cools down and becomes less fluid as it flows into these gaps due to proximity to the furnace sidewalls and water jacket, the gaps remain filled with air for extended periods. This results in the molybdenum electrode within these gaps being continuously exposed to a high-temperature, oxygen-rich environment, leading to more severe oxidation and corrosion compared to other parts of the electrode. The resulting pitting from oxidation weakens the structural strength of the molybdenum electrode in these gaps, making it prone to breakage under gravity. This significantly shortens the lifespan of the molybdenum electrode. Therefore, to extend the lifespan of the molybdenum electrode, reduce its replacement frequency, and thus lower glass production costs and improve efficiency, it is necessary to overcome the problem of molybdenum electrodes easily breaking at the inner end of the electrode brick hole due to oxidation and corrosion. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide an anti-oxidation fracture structure for fluxing electrodes, which solves the technical problem that fluxing electrodes are prone to fracture at the inner end of the electrode brick hole due to oxidation and corrosion, thereby achieving the effect of reducing glass production costs and improving production efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An anti-oxidation and fracture structure for a fluxing electrode includes a molybdenum electrode. A water-cooling jacket is fitted over the molybdenum electrode and is laterally inserted into an electrode brick hole on the side wall of a glass furnace. One end of the molybdenum electrode is located inside the glass furnace as a heating end, and the other end is located outside the glass furnace as a wiring end. The water-cooling jacket is slidably fitted with the electrode brick hole and can slide axially. A push-pull drive mechanism is provided outside the glass furnace, which is connected to the water-cooling jacket and can drive the water-cooling jacket to slide axially.

[0007] Furthermore, the molybdenum electrode is rotatably coupled with the water-cooling jacket, and the push-pull drive mechanism is equipped with a rotary drive mechanism that can be driven to move synchronously with the water-cooling jacket. The rotary drive mechanism is connected to the terminal block and can drive the molybdenum electrode to rotate.

[0008] Furthermore, a vertical electrode plate is fixedly provided at the heating end. The surface area of ​​the electrode plate is larger than the cross-sectional area of ​​the molybdenum electrode, and the electrode plate is electrically connected to the molybdenum electrode.

[0009] Furthermore, the heating end extends to form a connecting section with external threads. The connecting section passes through the electrode plate and is threaded with an anti-loosening nut. A stepped surface facing the electrode plate is formed between the connecting section and the molybdenum electrode. The electrode plate abuts against the stepped surface and the anti-loosening nut, respectively.

[0010] Furthermore, the push-pull drive mechanism includes a guide rail, a slider, and a push-pull drive assembly. The slider is slidably mounted on the guide rail and can be driven by the push-pull drive assembly to slide along the guide rail. The slider is connected to the water cooling jacket to drive the water cooling jacket to move axially.

[0011] Furthermore, the push-pull drive assembly is a linear motor or a motor-driven rolling resistance screw.

[0012] Furthermore, there are two guide rails arranged in parallel and spaced apart, with a mounting bracket installed between the two sliders and connected to each slider respectively, and the water cooling jacket is connected to the mounting bracket.

[0013] Furthermore, the water-cooling jacket is detachably connected to the mounting bracket via clamps.

[0014] Furthermore, the rotary drive mechanism includes a rotary motor and a drive wheel. The drive wheel is synchronously rotated and sleeved outside the terminal. The rotary motor is mounted on the mounting bracket and is connected to the drive wheel for driving the molybdenum electrode to rotate.

[0015] Furthermore, the guide rail is mounted on the support plate, and a lifting support frame is provided below the support plate to make the height of the support plate adjustable.

[0016] Furthermore, there are at least two lifting support frames, each comprising two intersecting and rotatably connected support rods, the upper ends of which are rotatably connected to a support plate, so that the support height of the lifting support frame can be changed by adjusting the included angle of the two intersecting support rods.

[0017] Furthermore, the support plate protrudes downward to form connecting lugs that correspond one-to-one with the support rods. The upper end of the support rod has a locking bolt that runs horizontally through and is rotatably engaged. The locking bolt is threaded to the shaft hole of the corresponding connecting lug. The support rod is located between the head of the locking bolt and the connecting lug, so that the support rod can be clamped and the support height of the lifting support frame can be locked by turning the locking bolt.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The anti-oxidation and fracture structure for the fluxing electrode described in this utility model features a push-pull drive mechanism installed outside the glass furnace. This mechanism drives the water-cooling jacket to move the molybdenum electrode axially back and forth, disturbing the molten glass. This not only allows the molten glass to enter the gap between the inner end of the electrode brick hole and the molybdenum electrode, eliminating air and reducing the degree of oxidation and corrosion of the molybdenum electrode at the inner end of the electrode brick hole, but also, compared to the molten glass submerging the molybdenum electrode as the liquid level rises, the disturbed molten glass can more quickly envelop the molybdenum electrode and reduce the possibility of air bubbles on the surface of the molybdenum electrode. This effectively solves the problem of molybdenum electrodes easily breaking at the inner end of the electrode brick hole due to oxidation and corrosion, which helps to extend the service life of the molybdenum electrode, reduce the replacement frequency of the molybdenum electrode, and thus reduce production costs and improve production efficiency.

[0020] 2. The anti-oxidation and fracture structure of the fluxing electrode described in this utility model has an electrode plate fixedly installed at the heating end of the rod-shaped molybdenum electrode. This not only increases the contact area between the fluxing electrode and the glass raw material or molten glass, thereby improving the heating and fluxing effect, but also enhances the disturbance effect on the molten glass when the molybdenum electrode moves back and forth with the help of the electrode plate. This promotes the molten glass to fill the gaps more quickly and avoids the formation of bubbles on the surface of the molybdenum electrode. In addition, it can also enhance the flow of molten glass and promote the homogenization and heat circulation of molten glass.

[0021] 3. The anti-oxidation and fracture structure for the fluxing electrode described in this utility model is equipped with a push-pull drive mechanism mounted on a support plate with a lifting support frame below. A water-cooling jacket is detachably connected to the mounting frame by a clamp. The water-cooling jacket can be separated from the mounting frame by loosening the clamp. When the push-pull drive mechanism is connected to push and pull other molybdenum electrodes, the height of the support plate can be adjusted by the lifting support frame so that the height of the guide rail and slider can be adapted to the molybdenum electrodes at different positions on the side wall of the glass furnace, which is beneficial to improving practicality and reducing the cost of use.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Example:

[0029] Please see Figure 2 and Figure 4 An anti-oxidation and fracture structure for a fluxing electrode includes a molybdenum electrode 1, an outer sleeve of which is fitted with a water-cooling jacket 2. The water-cooling jacket 2 is laterally inserted into an electrode brick hole on the side wall 3 of a glass furnace. There is a gap between the inner end of the water-cooling jacket 2 and the inner end of the electrode brick hole to avoid direct contact between the water-cooling jacket 2 and the high-temperature molten glass and to reduce the influence of the water-cooling jacket 2 on the inner end temperature of the molybdenum electrode 1 and the furnace temperature. One end of the molybdenum electrode 1 is located inside the glass furnace as a heating end 5, and the other end is located outside the glass furnace as a wiring end 6. The water-cooling jacket 2 is slidably fitted with the electrode brick hole and can slide axially. A push-pull drive mechanism 7 is provided outside the glass furnace, which is connected to the water-cooling jacket 2 and can drive the water-cooling jacket 2 to slide axially.

[0030] The anti-oxidation and fracture structure for the fluxing electrode described in this utility model, during use, causes the push-pull drive mechanism 7 to drive the water-cooled jacket 2 to slide axially and push the rod-shaped molybdenum electrode 1 into the furnace. The heating end 5 moves away from the electrode brick hole in the glass furnace and reaches a preset position, such as... Figure 3As shown, the molybdenum electrode 1 is then activated to heat the glass raw material in the glass furnace. When the molten glass is about to submerge the molybdenum electrode 1, the push-pull drive mechanism 7 drives the water-cooled jacket 2 to slide axially and pull the molybdenum electrode 1 out of the furnace. The heating end 5 moves away from the electrode brick hole in the glass furnace. Then, the push-pull drive mechanism 7 pushes the molybdenum electrode 1 into the furnace, and the heating end 5 moves away from the electrode brick hole in the glass furnace and reaches the preset position, such as... Figure 2 As shown, the push-pull drive mechanism 7 repeatedly pushes and pulls the molybdenum electrode 1 until the molten glass completely submerges the molybdenum electrode 1 and the electrode brick hole. Due to the limited fluidity and certain viscosity of the molten glass, it easily adheres to the molybdenum electrode 1. When the molybdenum electrode 1 moves back and forth, it not only disturbs the molten glass along the axial direction of the molybdenum electrode 1, causing the molten glass to enter the gap between the inner end of the electrode brick hole and the molybdenum electrode 1, but also causes the molten glass near the molybdenum electrode 1 to surge upward to a certain extent due to the flow lag. This accelerates the molten glass from enveloping the molybdenum electrode 1 and prevents air bubbles from appearing on the surface of the molybdenum electrode 1. The heating end 5 finally stops at the preset position to continue heating in conjunction with the glass furnace. In this embodiment, the length of the molybdenum electrode 1 extending into the furnace is 150 mm, the push-pull stroke of the molybdenum electrode 1 is 50-100 mm each time, the frequency is 2-4 times per minute, and the duration is 30 minutes. Trial experiments show that these parameters can make the air removal rate in the electrode brick hole exceed 95%, and reduce the oxidation erosion rate of the molybdenum electrode 1 at the electrode brick hole by 80%.

[0031] The anti-oxidation and fracture structure for the fluxing electrode of this utility model involves inserting the water-cooling jacket 2 into the electrode brick hole on the side wall 3 of the glass furnace. The water-cooling jacket 2 is not fixed, allowing it to remain in the electrode brick hole and slide axially. A push-pull drive mechanism 7 is installed outside the glass furnace, driving the water-cooling jacket 2 to move the molybdenum electrode 1 axially. In use, the movement begins when the molten glass is about to submerge the molybdenum electrode 1 or just submerges it, causing the molybdenum electrode 1 to move back and forth axially, disturbing the molten glass. This not only encourages the molten glass to enter the inner end of the electrode brick hole and interact with the molybdenum electrode... The gap between electrodes 1 eliminates air, reducing the degree of oxidation and corrosion of the molybdenum electrode 1 at the inner end of the electrode brick hole. Compared to the molten glass submerging the molybdenum electrode 1 as the liquid level rises, the disturbed molten glass can wrap around the molybdenum electrode 1 more quickly and reduce the possibility of air bubbles on the surface of the molybdenum electrode 1. Therefore, this invention can effectively solve the problem that the molybdenum electrode 1 is prone to breakage at the inner end of the electrode brick hole due to oxidation and corrosion, which is beneficial to extending the service life of the molybdenum electrode 1, reducing the replacement frequency of the molybdenum electrode 1, thereby reducing production costs and improving production efficiency.

[0032] Please see Figure 2 and Figure 4A vertical electrode plate 8 is fixedly provided at the heating end 5. The surface area of ​​the electrode plate 8 is larger than the cross-sectional area of ​​the molybdenum electrode 1, and the electrode plate 8 is electrically connected to the molybdenum electrode 1. In this way, the electrode plate 8 is fixedly provided at the heating end 5 of the rod-shaped molybdenum electrode 1, which not only increases the contact area between the fluxing electrode and the glass raw material or glass melt, thereby improving the heating and fluxing effect, but also increases the disturbance effect on the glass melt when the molybdenum electrode 1 moves back and forth with the help of the electrode plate 8, thereby promoting the glass melt to fill the gaps more quickly and avoiding the appearance of bubbles on the surface of the molybdenum electrode 1. In addition, it can also enhance the flow of the glass melt, promote the homogenization of the glass melt and the heat flow circulation. In practice, the electrode plate 8 can be a circular molybdenum plate or a square molybdenum plate, and the conductive connection between the electrode plate 8 and the molybdenum electrode 1 can be welding or threaded conductive connection.

[0033] Please see Figure 2 and Figure 4 The heating end 5 extends to form a connecting section 9 with external threads. The connecting section 9 passes through the electrode plate 8 and is threadedly connected to an anti-loosening nut 10. A stepped surface facing the electrode plate 8 is formed between the connecting section 9 and the molybdenum electrode 1. The electrode plate 8 abuts against the stepped surface and the anti-loosening nut 10 respectively. In this way, the molybdenum electrode 1 and the electrode plate 8 are designed separately, which is convenient for processing, manufacturing and transportation. The rod-shaped molybdenum electrode 1 is connected to the electrode plate 8 through the connecting section 9 and the anti-loosening nut 10. The connection is not only stable and reliable, but also easy to install, disassemble and replace.

[0034] In implementation, the push-pull drive mechanism 7 can employ linear drive elements such as electric actuators and cylinders. Please refer to [link / reference]. Figure 2 and Figure 4 In this embodiment, the push-pull drive mechanism 7 includes a guide rail 11, a slider 12, and a push-pull drive assembly (not shown in the figure). The slider 12 is slidably disposed on the guide rail 11 and can be driven by the push-pull drive assembly to slide along the guide rail 11. The slider 12 is connected to the water cooling jacket 2 to drive the water cooling jacket 2 to move axially. The push-pull drive assembly adopts a linear motor or a motor-driven rolling resistance screw. In this way, compared with directly using linear drive elements such as electric actuators and cylinders, the push-pull drive mechanism 7 composed of the guide rail 11, slider 12, and push-pull drive assembly provides a more stable driving force and facilitates more accurate control of the push-pull distance.

[0035] Please see Figure 4 There are two guide rails 11 arranged in parallel and spaced apart. The mounting bracket 13 is located between the two sliders 12 and is connected to the two sliders 12 respectively. The water cooling jacket 2 is connected to the mounting bracket 13. In this way, the two guide rails 11 guide the movement of the water cooling jacket 2, making it more stable and reliable.

[0036] Please see Figure 3 and Figure 4The water-cooled jacket 2 is detachably connected to the mounting bracket 13 via clamp 14. This facilitates the connection, fixation, and separation of the water-cooled jacket 2 and the mounting bracket 13. In use, when the push-pull drive mechanism 7 moves the molybdenum electrode 1 back and forth through the water-cooled jacket 2, allowing the molten glass to enter the gap between the inner end of the electrode brick hole and the molybdenum electrode 1 and expel air, the water-cooled jacket 2 is fixed to the side wall 3 of the glass furnace via flange 4. The clamp 14 is loosened to separate the water-cooled jacket 2 from the mounting bracket 13. The push-pull drive mechanism 7 can continue to connect and push other molybdenum electrodes 1, which is beneficial to improving practicality and reducing usage costs. In this embodiment, the clamp 14 is a semi-circular clamp 14, which is adapted to the shape of the water-cooled jacket 2.

[0037] In addition, in this embodiment, the molybdenum electrode 1 is designed to rotate with the water-cooling jacket 2. A rotary drive mechanism (not shown in the figure) is provided on the push-pull drive mechanism 7. The rotary drive mechanism can be driven by the push-pull drive mechanism 7 to move axially synchronously with the water-cooling jacket 2. The rotary drive mechanism is connected to the terminal 6 and can drive the molybdenum electrode 1 to rotate. Specifically, the molybdenum electrode 1 is not fixed in the water-cooling jacket 2, and a lubricating coating with good thermal conductivity (such as high-purity graphite and hexagonal boron nitride) is provided on the inner wall of the water-cooling jacket 2 and the surface of the shaft section where the molybdenum electrode 1 and the water-cooling jacket 2 mate. This reduces the relative rotational wear between the molybdenum electrode 1 and the water-cooling jacket 2 while ensuring the cooling effect of the water-cooling jacket 2 on the molybdenum electrode. The rotary drive mechanism includes a rotary... The rotating motor and drive wheel are synchronously mounted on the outside of the terminal 6. The rotating motor is mounted on the mounting bracket 13 and connected to the drive wheel. Specifically, it can adopt a gear drive or belt drive structure to drive the molybdenum electrode 1 to rotate. In this way, when the molten glass formed by the melting of the glass raw material is about to submerge the molybdenum electrode 1, and the push-pull drive mechanism 7 repeatedly pushes and pulls the molybdenum electrode 1, the rotating drive mechanism can also drive the molybdenum electrode 1 to reciprocate within a certain angle range without affecting the electrical connection of the terminal 6. This allows the molten glass to wrap around the molybdenum electrode 1 more quickly and avoids the formation of bubbles on the surface of the molybdenum electrode 1, thereby further reducing the degree of oxidation and corrosion of the molybdenum electrode 1 and extending the service life of the molybdenum electrode 1.

[0038] Please see Figure 3 and Figure 4 The guide rail 11 is set on the support plate 15, and the support plate 15 is provided with a lifting support frame 16 below it so that the height of the support plate 15 is adjustable. In this way, when the clamp 14 is loosened to separate the water cooling jacket 2 from the mounting frame 13, and the push-pull drive mechanism 7 is connected to push and pull other molybdenum electrodes 1, the height of the support plate 15 can be adjusted by the lifting support frame 16 so that the height of the guide rail 11 and the slider 12 can be adapted to the molybdenum electrodes 1 at different positions on the side wall 3 of the glass furnace, which is beneficial to improving practicality and reducing the cost of use.

[0039] Please see Figure 2 and Figure 3There are at least two lifting support frames 16. Each lifting support frame 16 includes two cross-connected and rotatably linked support rods 17. The upper ends of the support rods 17 are rotatably connected to the support plate 15 so that the support height of the lifting support frame 16 can be changed by adjusting the included angle of the two cross-connected support rods 17. In this way, compared with lifting using components such as telescopic rods and cylinders, the lifting support frame 16 uses two cross-connected and rotatably linked support rods 17, which is not only simple in structure but also has a lower cost.

[0040] Please see Figure 2 and Figure 3 The support plate 15 protrudes downward to form connecting lugs 18 that correspond one-to-one with the support rod 17. The upper end of the support rod 17 has a locking bolt 19 that passes through laterally and is rotatably engaged. The locking bolt 19 is threadedly connected to the shaft hole of the corresponding connecting lug 18. The support rod 17 is located between the head of the locking bolt 19 and the connecting lug 18, so that the support rod 17 can be clamped and the support height of the lifting support frame 16 can be locked by turning the locking bolt 19. In this way, the locking bolt 19 serves as both a rotating shaft for rotatable connection and a height lock, making the structure of the lifting support frame 16 simpler and more practical.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
