Description

Technical Field

[0001] The utility model belongs to the field of cable processing, and more specifically relates to high-temperature resistant cable vulcanizing equipment. Background Art

[0002] With the increasing emphasis on renewable energy utilization and the continuous development of photovoltaic power generation technology, the requirements for cables are becoming increasingly stringent, especially for applications in high-temperature environments. High-temperature resistant photovoltaic cables require the use of heat-resistant materials, such as specialized insulation and conductor materials. Common insulation materials include fluoroplastics and silicone rubber, while conductor materials are typically copper or aluminum. Advanced manufacturing processes and equipment are also required to ensure material stability and electrical performance during cable manufacturing. For example, specialized extrusion processes, heating treatments, and vulcanization treatments are employed to ensure cable reliability and stability in high-temperature environments.

[0003] A vulcanizing pipe is a device used to vulcanize rubber products with steam. An improvement on the traditional vulcanizing tank, it is a cylindrical container with a convex head. As a pressure vessel that requires frequent opening, the steam pressure during rubber vulcanization generally does not exceed 1 MPa gauge, and the temperature is below approximately 180°C. The vulcanizing pipe is subject to alternating loads, and cracks often develop at the feed opening. During operation, the internal pressure must be completely relieved before the feed opening can be opened. To ensure this, a pressure relief and feed opening interlocking device must be installed to prevent accidents caused by opening the feed opening before full pressure relief.

[0004] Existing vulcanization pipes have a single function: to vulcanize the rubber on the cable surface using steam. The treatment effect on the cable surface varies depending on the composition of the steam. Water vapor alone can easily oxidize the iron inside the cable, thereby degrading cable performance.

[0005] For example, the patent document with Chinese patent application number: CN201010567431.8 and publication date: August 17, 2011, discloses a high-temperature, low-pressure steam continuous vulcanization device for rubber wires and cables, which inputs low-pressure steam of 0.4 MPa or less into the vulcanization pipeline, and at the same time, short-circuit heats each vulcanization pipe in the vulcanization section of the vulcanization pipeline; the high-temperature, low-pressure steam continuous vulcanization device for rubber wires and cables includes a vulcanization section, which is composed of a plurality of vulcanization pipes connected together, and the vulcanization pipe is composed of a high-temperature resistant stainless steel seamless pipe 7, an asbestos insulation layer 8 wrapped around the outer periphery of the steel pipe 7, and an insulation fixing layer 9 fixed to the outer periphery of the asbestos insulation layer 8, a temperature reflecting layer 10 is provided between the steel pipe 7 and the asbestos insulation layer 8, a cavity is provided between the steel pipe 7 and the temperature reflecting layer 10, an electric heating pipe 11 is provided in the cavity, and the material of the insulation fixing layer 9 is aluminum alloy.

[0006] For example, the patent document with Chinese patent application number: CN202010890310.0 and publication date: November 6, 2020, discloses a steam vulcanization process for power cables. The cable conductor is released and enters the steam vulcanization device through a first wire pulling device. After the cable conductor completes steam vulcanization cross-linking, it is guided by a second wire pulling device and wound on the take-up roller.

[0007] Both of the above solutions use a single steam vulcanization method to treat the rubber on the surface of the cable, but the vulcanization effect is not ideal. Summary of the Invention

[0030] The following describes in detail exemplary embodiments of the present invention. Although these exemplary embodiments are described in sufficient detail to enable those skilled in the art to implement the present invention, it should be understood that other embodiments may be implemented and various changes may be made to the present invention without departing from the spirit and scope of the present invention. The following more detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but is merely for illustration and does not limit the description of the features and characteristics of the present invention, in order to propose the best way to perform the present invention and to enable those skilled in the art to implement the present invention. Therefore, the scope of the present invention is limited only by the appended claims.

[0031] Example 1

[0032] A high-temperature resistant cable vulcanizing equipment is used for vulcanizing cables to improve the surface quality of the cables. The specific structure and technical effects are described in detail below.

[0033] like Figure 1 As shown, the vulcanization equipment includes a vulcanization pipeline 1, a solution bottle 7, an argon gas delivery pipe 8, and a steam delivery pipe 9. The vulcanization pipeline 1 is provided with an inlet 4 and a discharge port 13 at each end. The vulcanization pipeline 1 is connected to a vulcanization gas delivery pipe. The argon gas delivery pipe 8 and the steam delivery pipe 9 are connected to external argon and steam sources, respectively. The solution bottle 7 is connected to the argon gas delivery pipe 8 on one side and to the vulcanization gas delivery pipe on the other side. The steam delivery pipe 9 is connected to the vulcanization gas delivery pipe. A fixed bracket 2 is mounted on a base at the bottom of the vulcanization pipeline 1.

[0034] By improving the structure of the vulcanizing gas conveying device of the vulcanizing pipeline, different types of solutions can be added to the solution bottle 7 for special cable surface materials, mixed with argon and steam, and then input into the vulcanizing pipeline 1 to perform vulcanization on the cable. Compared with single steam vulcanization, the vulcanization effect of the cable can be effectively improved, and the processing quality of the cable can be guaranteed.

[0035] In this embodiment, the solution in solution bottle 7 is an ethanol solution containing tetramethyl isopropyl titanate. Argon gas passes through the solution and mixes with steam before entering the vulcanization pipe 1. A feed port 4 feeds titanium dioxide powder into the vulcanization pipe 1. During the vulcanization process, the tetramethyl isopropyl titanate decomposes due to heat within the vulcanization pipe, forming a rubber and titanium dioxide composite coating on the cable surface, improving the cable's heat resistance and insulation properties.

[0036] In addition, a heating device 3 is provided in the vulcanization pipeline 1 . At the same time, a temperature measuring device 5 is installed on the vulcanization pipeline 1 , which can accurately control the temperature in the vulcanization pipeline, thereby improving the vulcanization effect.

[0037] The vulcanization pipeline 1 is connected to a drain pipe 10 for relieving pressure. A safety valve 11 is also installed on the vulcanization pipeline 1 and connected to a backup drain pipe 6. The safety valve 11 ensures stable pressure within the vulcanization pipeline 1, preventing accidents. If the drain pipe 10 becomes clogged, the backup drain pipe 6 can relieve pressure, ensuring normal production.

[0038] Flow valves are installed at the feed port 4 and the discharge port 13 to achieve controllable adjustment of the material inlet and outlet volume. A pressure measuring device 12 is installed on the vulcanization pipeline 1, and the flow valves at the feed port 4 and the discharge port 13 are electrically connected to the pressure measuring device 12. This ensures that the feed port and the discharge port are opened only after the pressure is completely relieved, thus avoiding safety accidents.

[0039] In this embodiment, each device of the vulcanization equipment is electrically connected to a central control device 14 installed on the vulcanization pipeline 1. The central control device 14 adopts existing mature equipment such as a computer or a PLC controller, which belongs to the existing technology known to those skilled in the art and will not be described in detail here.

[0040] In summary, the high-temperature resistant cable vulcanizing equipment of this embodiment can effectively improve the vulcanization effect of the rubber on the cable surface and ensure the processing quality of the cable by improving the structure of the vulcanizing equipment.
