Description

Technical Field

[0001] This utility model relates to the field of heating tube technology, and in particular to an insulated and safe heating tube that isolates copper hoop creepage. Background Technology

[0002] As a universal heating element that efficiently converts electrical energy into heat energy, heating elements are widely used in industrial production (such as heating petrochemical pipelines and drying food processing), household appliances (such as auxiliary heating for electric water heaters and electric ovens), and special applications (such as insulation for data center server rooms and low-temperature preheating for portable outdoor equipment) due to their advantages of compact structure, rapid heating, and convenient temperature control. In practical applications, the electrical safety of heating elements is a core technical requirement, especially the insulation performance between the copper clamp (high-voltage end) and the metal shell, which directly affects the stability of equipment operation and personnel safety.

[0003] If the creepage distance between high-voltage components and accessible metal parts is insufficient, excessively high electric field strength can easily lead to "creeping phenomena": current is abnormally conducted along the insulating surface to the metal casing, causing the casing to become charged. This problem is particularly prominent in traditional heating tubes: on the one hand, traditional heating tubes rely directly on the gap between the casing and the copper clamp for insulation, and the creepage distance often fails to meet the standards for high-voltage scenarios or precision environments (such as the low-interference requirements of computer rooms); on the other hand, the heat generated by the heating tube during operation accelerates the aging and embrittlement of insulating components (such as ordinary plastic gaskets), further reducing the creepage distance. Insufficient creepage distance makes the metal casing charged, which can easily lead to electric shock to operators. Creeping phenomena may cause insulation breakdown, resulting in a short circuit between the copper clamp and the metal casing. In scenarios such as data centers and precision instrument heating, it may also interfere with the signal transmission and operational stability of core equipment. Utility Model Content

[0004] The purpose of this utility model is to propose an insulated and safe heating tube that isolates copper hoop creepage in order to solve the problem of insufficient creepage distance of existing heating tubes.

[0005] To achieve the above objectives, this utility model employs the following technology: an insulating and safe heating tube that isolates copper hoop creepage, comprising: The outer casing provides mechanical protection for the heating element; A heating mechanism, comprising an electric heating tube arranged along the axis of the outer shell mechanism, wherein the electric heating tube is provided with a plurality of copper hoops carrying high voltage, and wherein an insulating component for increasing the creepage distance between the copper hoops and the outer shell mechanism is detachably installed on the outer shell mechanism; A piping system capable of heating the fluid flowing inside it via an electric heating element.

[0006] As a further description of the above technical solution: the outer shell mechanism includes a shell, and a first end cover and a second end cover are respectively assembled at both ends of the shell by bolts.

[0007] As a further description of the above technical solution: the insulating component includes an insulating plate, on which a card holder for contacting the heating element is integrally formed, and a through hole is opened in the middle of the insulating plate. The material of the insulating component includes at least one of ceramic, plastic, high-temperature silicone, and mica sheet.

[0008] As a further description of the above technical solution: the number of insulating components matches the number of copper hoops, wherein the copper hoops are located inside the through holes of the insulating plate.

[0009] As a further description of the above technical solution: the housing is provided with mounting holes, and the insulating plate is detachably mounted on the housing by means of fixing bolts and mounting holes.

[0010] As a further description of the above technical solution: the housing is also equipped with a reinforcing member through the mounting hole, one end of the reinforcing member abuts against the heating tube, and the reinforcing member and the insulating member are arranged in an alternating manner in the axial direction of the housing.

[0011] As a further description of the above technical solution: the pipeline mechanism includes a conveying pipe, and one end of the conveying pipe is provided with a heating pipe that passes through the electric heating tube through a bend.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: By designing the insulating sheet, the risk of current being conducted along the insulating surface to the metal casing is eliminated, preventing electric shock accidents caused by a live casing. The insulating sheet can prevent insulation breakdown and short circuits caused by creepage, avoiding burnout of internal components (such as heating wires) and damage to the upstream power supply system, ensuring stable operation of the equipment. The insulating components can withstand high temperatures under heating conditions, reducing insulation aging and loss, extending the overall service life of the heater, and reducing maintenance and replacement frequency and costs.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-5 This embodiment provides an insulating safety heating tube that isolates copper hoop creepage, including a shell mechanism 10, a heating mechanism 20, and a pipeline mechanism 30. The shell mechanism 10 includes a shell 11, and the two ends of the shell 11 are respectively fitted with a first end cap 12 and a second end cap 13 by bolts. The heating mechanism 20 has an electric heating tube 21. The pipeline mechanism 30 can heat the fluid flowing inside the electric heating tube 21. The pipeline mechanism 30 includes a delivery pipe 31, and one end of the delivery pipe 31 is provided with a heating pipe 33 that passes through the electric heating tube 21 through a bend end 32.

[0017] In this embodiment, after power is applied, the heating element 21 of the heating mechanism 20 first converts electrical energy into heat energy. Then, the fluid to be heated enters the system through the delivery pipe 31 of the pipeline mechanism 30, is guided by the bent end 32, and flows into the heating pipe 33 that passes through the heating element 21. The fluid directly exchanges heat with the heating element 21 in the heating pipe 33, absorbs heat, and its temperature rises. Finally, the heated fluid is output to the target scene through the pipeline. At the same time, the shell 11 of the outer shell mechanism 10 and the first end cap 12 and the second end cap 13, which are bolted together at both ends, provide sealing protection and structural support for the internal heating and pipeline components, realize the sealing of the shell 11, prevent external dust and moisture from entering the interior and affecting the insulation performance of the components, and facilitate the later disassembly and maintenance of the internal components.

[0018] Specifically, the heating mechanism 20 includes an electric heating tube 21 arranged along the axis of the outer shell mechanism 10. Several copper hoops 22 with strong current are provided on the electric heating tube 21. An insulating component 23 for increasing the creepage distance between the copper hoops 22 and the outer shell mechanism 10 is detachably installed on the outer shell mechanism 10. The insulating component 23 includes an insulating plate 231. A card seat 232 that contacts the electric heating tube 21 is integrally formed on the insulating plate 231. A through hole 233 is opened in the middle of the insulating plate 231. An installation hole 14 is opened on the shell 11. The insulating plate 231 is detachably installed on the shell 11 by the cooperation of the fixing bolt 234 with the installation hole 14.

[0019] When the device is powered on, high voltage is conducted to the heating tube 21 through the copper hoop 22 in the heating mechanism 20. The internal heating element, such as the nickel-chromium alloy wire, converts electrical energy into heat energy to provide energy for subsequent fluid heating. Since the copper hoop 22 is highly charged, if it is too close to the metal shell 11, creepage may occur. At this time, the insulating part 23, which is detachably installed on the shell 11, plays a protective role: the insulating plate 231 is spaced between the highly charged copper hoop 22 and the shell mechanism 10, which physically increases the creepage distance between the two and blocks the path of current conduction from the copper hoop 22 along the insulating surface to the shell, avoiding the risk of electric shock caused by the shell being charged. The integrally formed card holder 232 is in close contact with the heating tube 21, which not only fixes the heating tube 21 to prevent vibration and displacement, but also further isolates the heat source from the shell through the insulating material, enhancing safety. The through hole 233 in the middle can be adapted to the internal wiring or pipe installation without damaging the insulation structure.

[0020] It should be noted that the number of insulating components 23 matches the number of copper hoops 22. The copper hoops 22 are located within the through holes 233 of the insulating plate 231. The insulating components 23 are made of at least one of the following materials: ceramic, plastic, high-temperature silicone, and mica. Each copper hoop 22 carrying a strong current can be protected by an independent insulating component 23, ensuring that the insulation protection between each copper hoop 22 and the shell 11 is complete. Ceramic / mica has excellent high-temperature resistance, high insulation strength, and good chemical stability, which can adapt to the high-temperature environment when the heating element 21 is working, avoiding the melting and carbonization of the insulation material due to high temperature. In addition to basic insulation, high-temperature silicone / heat-resistant plastic has a certain degree of elasticity or toughness, which can not only adapt to the assembly gap between the copper hoop 22 and the through hole 233, but also buffer the vibration and impact during the heating process. At the same time, it can withstand long-term high temperature without aging and cracking. This material selection can ensure that the insulating components 23 will not fail due to the high temperature and vibration of the heating element's working environment, maintain a stable insulation and anti-creep effect for a long time, and extend the service life of the entire heating element.

[0021] In this embodiment, a reinforcement member 24 is also mounted on the housing 11 through the mounting hole 14. One end of the reinforcement member 24 abuts against the heating element 21, and the reinforcement member 24 and the insulating element 23 are arranged in an alternating manner in the axial direction of the housing 11. The design of the reinforcement member 24 can counteract the displacement force caused by vibration and thermal expansion and contraction of the heating element during operation, prevent the heating element 21 and the copper hoop 22 connected to it from shifting position, and prevent the copper hoop 22 from shifting closer to the housing 11 or squeezing the insulating element 23, thereby ensuring that the preset creepage distance of the insulating element 23 is not damaged and maintaining a stable insulation protection effect.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
