Description

Technical Field

[0001] This utility model relates to the field of graphite electrodes, and in particular to a novel graphite electrode. Background Technology

[0002] Graphite electrodes are key components for energy conversion and material processing in high-temperature smelting processes. They are mainly used in the high-temperature smelting of steel, ferroalloys, industrial silicon, yellow phosphorus, corundum and other non-ferrous metals and chemical raw materials.

[0003] With the development of industrial technologies such as electric arc furnace steelmaking and high-temperature smelting, traditional electrode materials have been gradually replaced due to their inability to withstand high temperatures and insufficient conductivity. Graphite, on the other hand, has become an ideal electrode material due to its excellent high-temperature resistance (it can withstand temperatures above 2000℃), good conductivity, and chemical stability.

[0004] Graphite electrodes often need to be connected in series longitudinally during use. However, since commercially available graphite electrodes still use traditional bolts for fixing, frequent disassembly and assembly consume a lot of time for staff. A small number of electrodes use their own structure for locking, but the two contact surfaces cannot fully adhere in the locked state, leading to abnormal electrode resistance. Therefore, a novel graphite electrode is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel graphite electrode, which aims to improve the problems of complex disassembly and assembly processes and insufficient tight contact between the contact surfaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel graphite electrode includes an electrode body and a square shell. The electrode body has four L-shaped grooves on its exterior. Sliding rods are fixedly connected to both sides of the exterior of the square shell. A stop block is slidably connected to the exterior of the sliding rod, and an L-shaped hook is fixedly connected to the exterior of the stop block.

[0008] As a further description of the above technical solution:

[0009] The square shell has a toothed groove inside, and a round shaft is provided on the outside of the square shell. A spring is sleeved on the outside of the round shaft, and a gear is fixedly connected to one end of the round shaft near the toothed groove.

[0010] As a further description of the above technical solution:

[0011] Two racks are slidably connected inside the square shell, and the end of the rack away from the gear is fixedly connected to the outside of the abutment block.

[0012] As a further description of the above technical solution:

[0013] The gear and the rack mesh.

[0014] As a further description of the above technical solution:

[0015] The gear and the tooth groove engage.

[0016] As a further description of the above technical solution:

[0017] A rotating ring is fixedly connected to the end of the circular shaft away from the gear.

[0018] As a further description of the above technical solution:

[0019] The L-shaped hook is slidably connected to the inner wall of the L-shaped groove.

[0020] As a further description of the above technical solution:

[0021] One end of the spring abuts against the outside of the gear, and the other end of the spring abuts against the inner wall of the square shell.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the L-shaped hook can engage with the L-shaped groove to connect two graphite electrodes in series. The L-shaped hook can be released from the L-shaped groove to separate the two connected graphite electrodes, thus achieving the effect of quickly connecting and disconnecting graphite electrodes in series.

[0024] 2. In this utility model, the gear can be fixed by engaging the gear and the tooth groove. When the gear is pulled out of the tooth groove, it can rotate, which drives the two L-shaped hooks to move and tightly engage the two series-connected graphite electrodes, thus achieving the effect of maintaining the resistance value of the graphite electrodes stably.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-2 This utility model provides an embodiment of a novel graphite electrode, comprising an electrode body 1 and a square shell 3. The electrode body 1 has four L-shaped grooves 2 evenly distributed circumferentially along its exterior. This design facilitates engagement with L-shaped hooks 12. Slide rods 10 are fixedly connected to both sides of the square shell 3. The slide rods 10 are horizontally positioned and polished to reduce friction with the abutment blocks 11. Abutment blocks 11 are slidably connected to the outside of the slide rods 10. The abutment blocks 11 have through holes that match the slide rods 10, allowing them to slide freely. L-shaped hooks 12 are fixedly connected to the outside of the abutment blocks 11. The bending angle of the L-shaped hooks 12 is 90°, and their dimensions match the L-shaped grooves 2. The slide rods 10 not only prevent displacement of the abutment blocks 11 during sliding but also increase their stability. They also improve the stability of the L-shaped hooks 12, ensuring no shaking occurs during engagement.

[0033] Reference Figures 3-5 The square shell 3 has internal toothed grooves 4 arranged in a ring on the circumferential surface inside the shell 3. The grooves are involute-shaped, providing good meshing performance. A circular shaft 5 is mounted on the outside of the shell 3, with its axis perpendicular to the central axis of the shell 3. One end of the shaft 5 extends into the interior of the shell 3. A spring 7, a cylindrical helical compression spring, is fitted around the outside of the shaft 5, providing good elasticity and stability. A gear 6 is fixedly connected to the end of the shaft 5 near the toothed grooves 4. The tooth profile of the gear 6 matches the tooth profile of the toothed grooves 4. When the gear 6 engages in the toothed grooves 4, it is locked and cannot rotate; when it disengages from the toothed grooves 4, it can rotate freely.

[0034] Reference Figures 3-5Inside the square shell 3, two racks 9 are slidably connected, located on either side of the gear 6 and meshing with it. The end of each rack 9 furthest from the gear 6 is fixedly connected to the outside of the abutment block 11, and the length of the rack 9 is aligned with the length of the slide rod 10. The square shell 3 has a guide rail adapted to the rack 9, allowing it to slide smoothly within the shell. This design makes the rack 9 more stable during adjustment; the square shell 3 provides support for the rack 9, and the gear 6 adjusts the position of the abutment block 11 simultaneously with the position of the rack 9.

[0035] Reference Figures 3-5 Gear 6 and rack 9 mesh, with gear 6 having the same module and rack 9 having the same pressure angle. This allows rack 9 to move synchronously and in opposite directions when gear 6 rotates. This meshing transmission method enables precise control of the movement distance of the stop block 11 and L-shaped hook 12.

[0036] Reference Figures 3-5 Gear 6 engages with tooth groove 4, and gear 6 is locked by tooth groove 4 when engaged. The depth and width of tooth groove 4 are matched with the tooth thickness and tooth height of gear 6 to ensure reliability and stability during engagement. When gear 6 engages with tooth groove 4, it can effectively prevent gear 6 from rotating, thereby locking the position of stop block 11 and L-shaped hook 12.

[0037] Reference Figures 1-4 A rotating ring 8 is fixedly connected to the end of the round shaft 5 away from the gear 6. The outer diameter of the rotating ring 8 is larger than that of the round shaft 5, and its outer surface is provided with anti-slip texture to increase friction and facilitate the operator's grip and rotation. When it is necessary to rotate the round shaft 5, the rotating ring 8 can be rotated. Because the surface of the round shaft 5 is smooth and has no force-bearing point, while the rotating ring 8 provides a part that is easy to apply force, making the operation more convenient.

[0038] Reference Figures 1-2 The L-shaped hook 12 is slidably connected to the inner wall of the L-shaped groove 2. A certain gap is left between the outer wall of the L-shaped hook 12 and the inner wall of the L-shaped groove 2 to ensure that the L-shaped hook 12 can slide freely in the L-shaped groove 2. The end of the L-shaped hook 12 is chamfered to facilitate its smooth sliding into the L-shaped groove 2.

[0039] Reference Figure 4 One end of spring 7 abuts against the outside of gear 6, and the other end abuts against the inner wall of the square shell 3. Spring 7 is always in a compressed state, providing an inward pressure to gear 6. When the rotating ring 8 is pulled to move gear 6 out of the tooth groove 4, spring 7 is further compressed, storing elastic potential energy; after the rotating ring 8 is released, spring 7 needs to reset, giving gear 6 an inward pressure, pressing it back into the tooth groove 4, thus achieving automatic locking of gear 6.

[0040] Working Principle: When two electrode bodies 1 need to be connected in series longitudinally, first place the two electrode bodies 1 head to head, ensuring that their axes coincide. Then, attach the square shell 3 to the outside of the electrode body 1, so that the L-shaped hook 12 abuts against the inner wall of the L-shaped groove 2. At this time, pull up the rotating ring 8, which will compress the spring 7, and the gear 6 will slide out of the tooth groove 4, releasing the locking state of the gear 6. Rotate the rotating ring 8, and the round shaft 5 will rotate accordingly, driving the gear 6 to rotate. Since the gear 6 meshes with the rack 9, the rotation of the gear 6 will cause the two racks 9 to move synchronously in opposite directions, thereby driving the abutment 11 and the L-shaped hook 12 to slide on the slide rod 10. When the L-shaped hook 12 slides into the bent part of the L-shaped groove 2, continue to rotate the rotating ring 8 until the two L-shaped hooks 12 and the L-shaped groove 2 are completely locked, at which point the contact surfaces of the two electrode bodies 1 are tightly fitted. This can stabilize the resistance value of the electrode body 1 and prevent excessive energy waste due to poor contact during the operation of the electrode body 1. When disassembly is required, simply pull up the rotating ring 8 again and rotate the rotating ring 8 to disengage the L-shaped hook 12 from the L-shaped groove 2, and the square shell 3 can be removed.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
