Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrode technology, specifically to a high-voltage resistant PTFE electrode structure. Background Technology
[0002] In industrial production, electrodes, as core components for energy conversion and signal transmission, are widely used in chemical, energy, and metallurgical fields. Electrodes used under high pressure and high temperature conditions face extremely harsh environmental challenges, and their performance stability directly determines the safety and efficiency of the production process. Existing electrode structures typically employ a single material or simple coating for protection, such as basic isolation achieved only through a metal shell or ordinary ceramic sleeve. However, ordinary protective layers are insufficient to withstand long-term high-pressure impacts and the penetration of corrosive media. Corrosive media can directly erode the core electrode, leading to damage, performance degradation, or even failure of the electrode core. Simultaneously, the significant differences in thermal expansion and contraction among components under high-temperature conditions, coupled with a lack of effective stress buffering structures, can easily cause problems such as coating peeling and sleeve cracking, further compromising the overall structural integrity of the electrode. Under high-pressure and high-temperature conditions, the electrode continuously generates heat. Existing electrodes often rely on a single heat dissipation component for heat dissipation, lacking a synergistic mechanism for heat conduction, heat storage, and temperature regulation. Heat tends to accumulate inside the electrode, accelerating the aging of the electrode core and surrounding components and potentially causing electrode performance parameters to drift, making it impossible to maintain a stable working state. Sudden temperature changes can further exacerbate stress damage between components, shortening the electrode's lifespan. Therefore, a high-pressure resistant PTFE-specific electrode structure is proposed. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a high-voltage resistant PTFE electrode structure, which solves the problem that high-voltage resistant PTFE electrodes cannot maintain a stable working state due to poor heat dissipation.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage resistant PTFE electrode structure, comprising an electrode body, wherein an electrode core is disposed within the cavity of the electrode body; The electrode body is equipped with a high-temperature resistant mechanism, which includes a high-temperature and high-pressure corrosion-resistant ceramic tube, an end cap, heat dissipation fins, and an inorganic adhesive layer. The electrode core is fitted with a high-temperature and high-pressure anti-corrosion ceramic tube, and an inorganic adhesive layer is coated between the high-temperature and high-pressure anti-corrosion ceramic tube and the electrode core. The inorganic adhesive layer is arranged in a honeycomb pattern.
[0005] Preferably, the end cap is welded to the front surface of the high-temperature and high-pressure corrosion-resistant ceramic tube; The heat dissipation fins are fixedly installed on the outer surface of the electrode body.
[0006] Preferably, the high-temperature resistant mechanism further includes a ceramic composite coating, which is applied to the outer surface of the inorganic adhesive layer and is arranged in a rectangular stacked manner.
[0007] Preferably, the high-temperature resistant mechanism further includes a thermally conductive silicone coating, which is applied to the outer surface of the ceramic composite coating.
[0008] Preferably, the high-temperature resistant mechanism further includes a phase change material composite coating, which is applied to the outer surface of the thermally conductive silicone coating and is arranged in a grid-like layered configuration.
[0009] Compared with the prior art, this utility model provides a high-voltage resistant PTFE electrode structure, which has the following beneficial effects: 1. This high-pressure resistant PTFE electrode structure uses a high-temperature, high-pressure corrosion-resistant ceramic tube to form an outer barrier against high-pressure corrosion. The rectangular layered ceramic composite coating extends the penetration path of corrosive media, and the honeycomb inorganic adhesive layer buffers thermal expansion and contraction stress and blocks heat transfer. Combined with end caps for dust prevention, the multi-layered structure works synergistically to significantly improve the structural stability of the electrode under high-pressure and high-temperature conditions, preventing the core component, the electrode core, from being corroded or damaged by pressure, and ensuring long-term reliable operation.
[0010] 2. This high-pressure resistant PTFE electrode structure features heat dissipation fins that increase the heat dissipation area of the electrode body to accelerate heat dissipation. The thermally conductive silicone coating quickly conducts heat from the inner layer to the outer layer. The grid-like layered phase change material composite coating absorbs and stores heat through phase change, releases heat, and regulates temperature. This closed-loop system of heat dissipation, heat conduction, and temperature regulation mitigates the impact of sudden temperature changes on the electrode core and other components, maintaining the electrode within a suitable temperature range and preventing performance degradation or structural failure due to overheating.

[0013] 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.
[0014] Please see Figure 1-3 This utility model provides a new technical solution: a high-pressure resistant PTFE special electrode structure, including an electrode body 1: as the main structural support, the electrode body 1 contains an electrode core 5, and at the same time provides an installation foundation for the high-temperature resistant mechanism, ensuring the overall structural stability, and resisting the direct impact of the external environment on the internal components. It is the core skeleton for realizing the overall shape and function of the electrode.
[0015] High-temperature and high-pressure corrosion-resistant ceramic tube 2: It is sleeved outside the electrode core 5. With the high temperature resistance, high pressure resistance and chemical inertness of the ceramic material, it forms the first protective barrier, which isolates the electrode core 5 from the erosion of high temperature, high pressure and corrosive media under complex working conditions, and ensures the stability of the core components.
[0016] End cap 3: Fixed to the front surface of high temperature and high pressure anti-corrosion ceramic tube 2, it plays a sealing and protective role, which can prevent dust, liquid and other impurities from entering the interior of the ceramic tube, while enhancing the structural strength of the end of the ceramic tube and preventing the end from being damaged due to pressure or temperature changes.
[0017] Heat dissipation fins 4: Installed on the outer surface of the electrode body 1, they increase the contact area with air, accelerate the dissipation of heat generated during electrode operation, prevent heat accumulation that could lead to excessively high temperatures in the electrode body and internal components, and maintain the electrode operating within a suitable temperature range.
[0018] Electrode core 5: Located inside the cavity of electrode body 1, it is a key component for the electrode to realize its core functions, such as signal transmission and conductivity. It directly participates in the conversion and transmission of electrical signals or energy, and its performance stability determines the overall working efficiency and accuracy of the electrode.
[0019] Inorganic adhesive layer 6: It is honeycomb-shaped and connected between the high-temperature and high-pressure anti-corrosion ceramic tube 2 and the electrode core 5. It not only achieves tight bonding and fixation between the two, but also absorbs the stress generated by vibration or thermal expansion and contraction due to the honeycomb structure, while also assisting in heat conduction.
[0020] Ceramic composite coating 7: Connected to the outer surface of inorganic adhesive layer 6, ceramic composite coating 7 is in the form of rectangular stacked layers, which further enhances high temperature resistance and corrosion resistance. The stacked structure can extend the penetration path of corrosive media, improve the protection time, and at the same time help to disperse heat, and work with other components to improve the high temperature resistance effect.
[0021] Thermally conductive silicone coating 8: Covered on the outer surface of ceramic composite coating 7, it utilizes the excellent thermal conductivity of thermally conductive silicone to quickly transfer the heat from the inside to the outside layer to subsequent heat dissipation components, reducing heat retention between coatings and improving overall heat dissipation efficiency.
[0022] Phase change material composite coating 9: It is connected in a grid pattern on the outer surface of thermally conductive silicone coating 8. The phase change material can store heat through heat absorption and phase change, and release heat when the temperature fluctuates, so as to play a role in temperature regulation, maintain the temperature stability of the environment around the electrode, and mitigate the impact of sudden temperature changes on the component.
[0023] This high-pressure resistant PTFE electrode structure achieves high-pressure and high-temperature resistance through the synergistic effect of multiple high-temperature resistant mechanisms: the phase change material composite coating first absorbs external heat and disperses it through the grid structure; the thermally conductive silicone coating efficiently conducts heat to the ceramic composite coating; the rectangular stacked structure enhances thermal barrier and pressure resistance; the honeycomb structure of the inorganic adhesive layer further buffers pressure and blocks heat transfer to the electrode core; the heat dissipation fins help the electrode body dissipate excess heat; and the high-temperature, high-pressure corrosion-resistant ceramic tube and end cap form an outer protective layer, jointly ensuring the stable operation of the electrode core under high-pressure conditions.
