Description

Technical Field

[0001] This utility model relates to the field of graphite electrode rod technology, specifically to a high-strength graphite electrode rod. Background Technology

[0002] Graphite electrode plates are installed in storage batteries and used as the positive and negative electrodes. Graphite electrodes are mainly made from petroleum coke and needle coke as raw materials and coal tar pitch as a binder. They are manufactured through calcination, batching, kneading, molding, roasting, graphitization, and machining. They are conductors that release electrical energy in the form of an electric arc to heat and melt the furnace charge in an electric arc furnace. According to their quality indicators, they can be divided into ordinary power, high power, and ultra-high power. Graphite electrodes mainly include four categories: ordinary power graphite electrodes, anti-oxidation coated graphite electrodes, high power graphite electrodes, and ultra-high power graphite electrodes.

[0003] For existing graphite electrode protection applications, such as the high-strength graphite electrode rod disclosed in publication (announcement) number CN215818678U, there are certain shortcomings, specifically as follows: 1. The protective layer is simple and cannot provide adequate protection during transportation; 2. The lack of a buffer and shock absorption protection structure means that when the graphite electrode is hit, the impact force is not buffered and damped, causing wear on the surface of the graphite electrode or damage to the internal cracks. This results in problems such as breakage or low arc efficiency during resistor use.

[0004] Therefore, a high-strength graphite electrode rod is needed. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a high-strength graphite electrode rod, aiming to improve and solve the technical problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength graphite electrode rod, comprising an inner protective sleeve fitted over the graphite electrode rod body. The inner protective sleeve has open ends, and snap-fit ​​bases are evenly distributed circumferentially on the outer side of each open end. The open ends are closed by a cover plate, and the cover plate has evenly distributed circumferentially distributed claws that engage with the snap-fit ​​bases. The cover plate seals the inner protective sleeve, thus protecting both ends of the graphite electrode rod body. A fixing plate is evenly distributed circumferentially on the outer side of the inner protective sleeve. The surface of the protective sleeve is uniformly provided with screw holes, and a nut base is threaded onto the screw holes. A limit shaft is provided on the top of the nut base. A protective tube is sleeved on the outside of the inner protective sleeve. Limit bases are evenly distributed circumferentially inside the protective tube. The limit shaft is movably inserted into the inside of the limit base, and the limit base is provided with a structure to prevent the limit shaft from sliding out. A buffer spring is sleeved on the outside of the limit shaft. The buffer spring abuts between the limit base and the nut base, so that when the protective tube is impacted, the elasticity of the buffer spring can play a role in buffering and shock absorption.

[0007] Preferably, a shock-absorbing buffer layer is provided between the inner protective sleeve and the graphite electrode rod body.

[0008] Preferably, the limiting bases are arranged in several circles along the axial direction of the protective tube.

[0009] Preferably, the outer circumference of the protective tube is uniformly distributed with support blocks.

[0010] Preferably, the snap-fit ​​base has an opening at the end of the snap-fit ​​claw in the insertion direction, and the snap-fit ​​claw is held in place by the opening to facilitate the disassembly and installation of the cover plate.

[0011] Preferably, the shock-absorbing buffer layer is made of soft rubber.

[0012] In summary, this utility model provides a high-strength graphite electrode rod, which employs an inner protective sleeve fitted over the graphite electrode rod body. The outer surface of the inner protective sleeve has evenly distributed elongated heat dissipation holes. Snap-fit ​​bases are evenly distributed on both sides of the inner protective sleeve, and cover plates are sealed and installed on both sides. The cover plates have evenly distributed circumferential claws that engage with the snap-fit ​​bases, achieving a sealed installation of the inner protective sleeve through the cover plates, thus providing better protection for the graphite electrode rod body. The limiting shaft is movably inserted into the limiting base. The bottom of the limiting base is set as limiting plate one, and the top of the limiting shaft is set as limiting plate two. Limiting plate two limits the installation of limiting plate one, preventing the limiting shaft from moving out of the limiting base. When the protective tube one is impacted or squeezed by pressure, the limiting shaft slides inside the limiting base, and the elastic buffering effect of buffer spring one plays the role of impact buffering and shock absorption of the protective tube one, thus realizing the protection of the internal graphite electrode rod body.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figures 1 to 6 As shown: This invention relates to a high-strength graphite electrode rod, which addresses the shortcomings of existing technologies such as a single protective layer for graphite electrodes, insufficient protective strength, and inadequate buffering and shock absorption, resulting in scratches and internal cracks on the outer surface of the graphite electrode, thus affecting its normal power supply.

[0016] In Example 1: The technical structure adopted in this utility model is as follows: It includes an inner protective sleeve 1 that is fitted over the graphite electrode rod body. Both ends of the inner protective sleeve 1 are open structures. Snap-fit ​​bases 2 are evenly distributed circumferentially on the outer side of the open structures. The open structures are closed by a cover plate 3. Claws 4 are evenly distributed circumferentially on the cover plate 3, and the claws 4 snap-fit ​​with the snap-fit ​​bases 2. The cover plate 3 closes the inner protective sleeve 1, thus protecting both ends of the graphite electrode rod body. Fixing plates 5 are evenly distributed circumferentially on the outer side of the inner protective sleeve 1. Screw holes 6 are evenly distributed on the surface of the fixing plates 5, and threads are installed on the screw holes 6. The device includes a nut base 7, with a limiting shaft 11 at its top. A protective tube 12 is sleeved on the outside of the inner protective sleeve 1. Limiting bases 13 are evenly distributed circumferentially inside the protective tube 12. The limiting shaft 11 is movably inserted into the inside of the limiting base 13, and the limiting base 13 is provided with a structure to prevent the limiting shaft 11 from sliding out. A buffer spring 14 is sleeved on the outside of the limiting shaft 11. The buffer spring 14 abuts between the limiting base 13 and the nut base 7, so that when the protective tube 12 is impacted, the elastic action of the buffer spring 14 can play a role in buffering and shock absorption.

[0017] Specifically, the inner protective sleeve 1 is fitted over the graphite electrode rod body. The outer surface of the inner protective sleeve 1 is provided with elongated heat dissipation holes 21. The two sides of the inner protective sleeve 1 are evenly distributed with snap-fit ​​bases 2. The two sides of the inner protective sleeve 1 are sealed with cover plates 3. The cover plates 3 are evenly distributed with claws 4 around their circumference. The claws 4 are snap-fitted with the snap-fit ​​bases 2 to achieve the sealing installation of the inner protective sleeve 1 through the cover plates 3, so as to better protect the graphite electrode rod body. The inner protective sleeve 1 has evenly distributed fixing plates 5 on its outer surface. A protective tube 12 is sleeved on the outer surface of the inner protective sleeve 1. Limiting bases 13 are evenly distributed circumferentially inside the protective tube 12. Screw holes 6 are evenly distributed on the surface of the fixing plates 5. Nut bases 7 are threaded onto the screw holes 6. A limiting shaft 11 is provided on the top of the nut base 7. A buffer spring 14 is sleeved on the outer surface of the limiting shaft 11. The limiting shaft 11 is movably inserted into the limiting base 13. The limiting base 13... The bottom is set with a limiting plate 22, and the top of the limiting shaft 11 is set with a limiting plate 23. The limiting plate 23 limits the installation of the limiting plate 22 to prevent the limiting shaft 11 from moving out of the limiting base 13. When the protective tube 12 is impacted or squeezed by pressure, the limiting shaft 11 slides inside the limiting base 13, and the elastic buffering effect of the buffer spring 14 plays a role in buffering and shock absorption of the impact of the protective tube 12, thus realizing the protection of the internal graphite electrode rod body.

[0018] In at least one embodiment, to further protect and dampen the graphite electrode rod body, a shock-absorbing buffer layer 15 is provided between the inner protective sleeve 1 and the graphite electrode rod body. The shock-absorbing buffer layer 15 serves to prevent wear between the graphite electrode rod body and the inner protective sleeve 1, and to further buffer and protect the graphite electrode rod body.

[0019] In at least one embodiment, to achieve a buffer protection installation of the graphite electrode rod body, the limiting base 13 is arranged in several circles along the axial direction of the protective tube 12.

[0020] Specifically, a limiting base 13 is set inside the protective tube 12. The limiting base 13 is installed with the fixing plate 5 on the inner protective sleeve 1 through the nut base 7, the limiting shaft 11, and the fixing plate 5. The structure of this patent can use a protective tube 12 with a length slightly larger than the length of the graphite electrode rod body. The protective tube 12 is an integral structure. This structure can achieve quick installation and strong integrity. By setting three rings of limiting base 13 at equal intervals in the front, back and middle parts inside the protective tube 12, the limiting base 13 is installed on the upper part of the screw hole 6, so that the protective tube 12 can be installed on the outside of the graphite electrode rod body, which plays a buffer protection role. The protective tube 12 can also be segmented and sleeved on the outside of the graphite electrode rod body. The protective tube 12 has several rings of limiting bases 13 arranged in an array at both ends along its axial direction. The limiting bases 13 are installed on the upper part of the screw hole 6. The limiting shaft 11 slides inside the limiting base 13, and the elastic buffering effect of the buffer spring 14 plays a role in buffering and shock absorption of the protective tube 12, thus achieving the protection of the internal graphite electrode rod body.

[0021] In Example 2: In order to ensure that the graphite electrode rod body can be stably placed after protective installation, and at the same time to further improve the protective strength of the protective tube 12, support blocks 16 are evenly distributed around the outer circumference of the protective tube 12.

[0022] In at least one embodiment, the snap-fit ​​base 2 has an opening 17 at the insertion end of the snap claw 4. The snap claw 4 is pressed downward through the opening 17, so that the snap claw 4 is disengaged from the snap-fit ​​base 2 for snap-fit ​​installation, so that the cover plate 3 can be disassembled and installed. After the inner protective sleeve 1 protects the graphite electrode rod body, the graphite electrode rod body can be easily and quickly removed.

[0023] In at least one embodiment, in order to protect the surface of the graphite electrode rod body, avoid scratches, and further improve the shock absorption and buffering effect, the shock absorption and buffering layer 15 is made of soft rubber.

[0024] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
