Description

Technical Field

[0001] This utility model relates to the field of oxidation rod technology, specifically to an electrofused oxidation rod. Background Technology

[0002] High-purity electrofused oxide rods exhibit excellent alkali resistance and electrical insulation at high temperatures. They also possess high thermal expansion coefficients and thermal conductivity, resulting in good light transmittance. They are widely used as high-temperature heat-resistant materials. In the ceramics industry, they are used as raw materials for translucent ceramic crucibles and substrates. In the electrical materials and electrical fields, they are used as fillers in magnetic devices, insulating materials, and various carriers.

[0003] Chinese Patent No. CN202322855987.2 discloses a porous high-purity electrofused oxidation rod, relating to the field of oxidation rod technology. The rod includes a rod body and a protective assembly. The rod body has an internal through-hole, and a copper wire is installed inside the through-hole. The protective assembly, used for external buffering, protection, and heat dissipation, is located on the outside of the rod body. The protective assembly includes a mounting ring, a protective rod, heat dissipation holes, a buffer pad, and a protective mesh cover. The protective rod is mounted on the inner side of the mounting ring, and the inner side of the protective rod has heat dissipation holes. The buffer pad is installed on the inner wall of the protective rod, and the protective mesh cover is installed outside the heat dissipation holes. This porous high-purity electrofused oxidation rod provides external protection through the mounting ring and protective rod. The buffer pad, made of rubber, acts as a buffer between the protective rod and the rod body. The heat dissipation holes dissipate heat, and the protective mesh cover provides dust protection without affecting heat dissipation.

[0004] To enhance the protection of the oxidation rod, external protective components such as mounting rings, protective rods, and rubber buffer pads are arranged on the oxidation rod. Although these protective components can enhance the buffering, they increase the structural complexity, which leads to obstruction of the heat dissipation path. Especially in high-temperature environments, the heat dissipation efficiency is reduced. Furthermore, the rubber buffer pads in the protective components are prone to aging and cracking in long-term high-temperature environments, losing their buffering function and potentially releasing pollutants that affect electrical insulation performance. Therefore, it is urgent to design an electrofused oxidation rod to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an electrofused oxidation rod to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrofused oxidation rod, comprising a cylindrical shell, a rod body at the top of the cylindrical shell, a sealing member at the bottom of the cylindrical shell, the cylindrical shell comprising a cylindrical shell and a filler, a plurality of through holes on the outside of the cylindrical shell, the filler being inserted into the inside of the cylindrical shell, a plurality of insertion holes at one end of the filler, a head threadedly connected to one end of the cylindrical shell, and a plurality of threaded grooves corresponding to the insertion holes at one end of the head, a through hole on one side of the inner wall of the threaded groove, and a plurality of vent holes at one end of the head.

[0007] The rod body includes a sealing threaded plug, which is threadedly connected inside the threaded groove.

[0008] The sealing threaded plug has a rod attached to one end by bolts, and the rod is inserted into the through hole and the insertion hole in sequence.

[0009] The rod has a core rod inserted into one end, and a connecting wire is electrically connected to one end of the core rod.

[0010] The sealing component includes a cover, and a threaded post is integrally formed at the center of the outer wall on one side of the cover.

[0011] The cylindrical shell has a threaded portion at one end of its opening, and the threaded column is threaded inside the threaded portion.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes the through holes on the exterior of the shell and the vent holes at the ends to form a three-dimensional heat dissipation channel. Combined with the multi-interlocking design of the filler, it achieves efficient heat diffusion without external protective components. This structure avoids the blockage of heat dissipation paths by traditional protective mesh covers. Simultaneously, the honeycomb through-hole layout improves heat conduction uniformity, significantly increasing heat dissipation efficiency in high-temperature environments. This invention replaces the rubber buffer pad with a rigid connection between a sealing threaded plug and a threaded groove, completely eliminating the risk of high-temperature aging. The independent interlocking design of the core rod and connecting wires, along with the insulation of thermal stress by the oxide ceramic material of the filler, ensures stable electrical insulation performance and prevents contaminant release. The threaded post of the sealing component mates with the threaded part of the shell, combined with the bolt installation structure of the rod, enabling quick disassembly of components such as the ends and the rod. Compared to existing multi-layered protective structures, maintenance time is significantly reduced. The interlocking design of the filler, while ensuring structural strength, reduces overall density through the honeycomb through-holes, simultaneously accommodating the dual functions of core rod conductivity and shell heat dissipation, making it suitable for lightweight applications such as aerospace and high-power electronic devices.

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.

[0016] Please see Figures 1-4 This utility model provides a technical solution: an electrofused oxidation rod, including a cylindrical shell 1, a rod body 2 at the top of the cylindrical shell 1, and a sealing member 3 at the bottom of the cylindrical shell 1. The cylindrical shell 1 includes a cylindrical shell 4 and a filler 15. The cylindrical shell 4 serves as the main load-bearing structure, and multiple through holes 10 on its exterior form a honeycomb-shaped heat dissipation channel to enhance heat diffusion efficiency. Under high-temperature conditions, heat is radiated and convected outward through the surface of the cylindrical shell 4 and the through holes 10. The filler 15 is inserted into the interior of the cylindrical shell 4, and its insertion hole 16 is used to accommodate the rod body 12 and fix the core rod 13. The filler 15 is made of oxide ceramic material, which isolates thermal stress. The outer shell 4 has multiple through holes 10. The filler 15 is inserted into the inner shell 4. One end of the filler 15 has multiple insertion holes 16. One end of the shell 4 is threadedly connected to the end head 5. The end head 5 is threadedly connected to the shell 4. Its thread groove 6 is aligned with the insertion hole 8 to ensure that the rod 12 is accurately inserted. Multiple vent holes 7 on the surface of the end head 5 and the through holes 10 of the shell 4 form a three-dimensional heat dissipation network. High-temperature gas is quickly discharged through the vent holes 7 to avoid heat accumulation. In addition, one end of the end head 5 has multiple thread grooves 6 corresponding to the insertion holes 16. One side of the inner wall of the thread groove 6 has an insertion hole 8. One end of the end head 5 has multiple vent holes 7. The outer shell 4 has honeycomb-shaped through holes 10 to form a three-dimensional heat dissipation channel, which, together with the vent holes 7 of the end head 5, constitutes an airflow circulation system to achieve efficient heat exchange without the interference of the mesh cover.

[0017] The rod component 2 includes a sealing threaded plug 11, which is threadedly embedded into the threaded groove 6 of the end 5 to achieve airtight sealing, replacing the traditional rubber buffer pad and avoiding high-temperature aging problems. The sealing threaded plug 11 is threaded inside the threaded groove 6, and a rod 12 is bolted to one end of the sealing threaded plug 11. The rod 12 is fixed to the end of the sealing threaded plug 11 by bolts and passes through the insertion hole 8 and the insertion hole 16 in sequence to form a rigid support. The core rod 13 inserted inside is connected to an external power source through the connecting wire 14. The heat generated when the current passes through the core rod 13 is conducted to the shell 4 for heat dissipation through the rod 12. The rod 12 is inserted into the insertion hole 8 and the insertion hole 16 in sequence, and the core rod 13 is inserted into one end of the rod 12. The core rod 13 is electrically connected to the connecting wire 14 at one end of the core rod 13.

[0018] The sealing component 3 includes a cover 17, with a threaded post 18 integrally formed at the center of one side of the outer wall of the cover 17. A threaded part 9 is provided at one end of the opening of the cylinder shell 4. The cover 17 is screwed into the threaded part 9 at the bottom of the cylinder shell 4 through the integrally formed threaded post 18 to achieve bottom sealing. This design supports quick disassembly, making it easy to clean the dust inside the cylinder shell 4 or replace the filler 15. The threaded post 18 is threaded inside the threaded part 9.

[0019] Working principle: Electrical energy is transmitted to the core rod 13 through the connecting wire 14, and then introduced into the electro-fusion oxidation system through the rod body 12. The high temperature generated during operation is evenly distributed to the shell 4 by the filler 15. The honeycomb through holes 10 and the vent holes 7 form a convection heat dissipation channel. The oxide ceramic material of the filler 15 also ensures electrical insulation.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
