Description

Technical Field

[0001] The present invention relates to the technical field of high temperature material processing, and in particular to a high temperature furnace designed for graphitized fiber processing, aiming to achieve a processing environment with a target temperature of 3000° C. while ensuring operational safety and equipment stability. Background Art

[0002] The processing of graphitized fiber requires an extremely high temperature environment, usually up to 3000°C, which poses a severe challenge to the heating materials, insulation materials and the structural design of the entire furnace. Traditionally, considering the conductivity of graphite, the use of high-voltage power distribution can theoretically achieve rapid heating, but it greatly increases the risk of electric shock and the difficulty of operation, posing a serious threat to the safety of users. Summary of the invention

[0003] To solve the above problems, the present invention proposes an innovative solution, which adopts a safe voltage power supply system of ≤36V, while ensuring the high temperature required for graphitization processing, significantly improving the safety performance of the equipment.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A graphitized fiber processing furnace, comprising a furnace body, a heating system, and a power supply and current distribution system;

[0006] Heating system: A heating resistor is provided in the upper part of the furnace body, and a 380V transformer is used to reduce the input voltage to 30-40V. This voltage range is far lower than the human safety voltage limit, effectively avoiding the risk of electric shock;

[0007] Power supply and current distribution system: The 380V transformer is connected to both ends of the heating resistor through an insulated wire, and the insulated wire is safely introduced into the furnace through an opening on the stainless steel plate in the middle of the furnace body.

[0008] Furthermore, the furnace body is made of high-strength carbon steel material, which has good high temperature resistance and mechanical strength, ensuring long-term stable operation in a high temperature environment.

[0009] Furthermore, the high power required by the heating resistor and the maximum secondary current are 8000A. To ensure the safety and efficiency of current transmission, 16 high-load-carrying cables are used to share the high current to ensure its long-term stable operation in a high-temperature environment.

[0010] Beneficial effects of the present invention:

[0011] It not only realizes the high temperature environment required for graphitized fiber processing, but also significantly improves the operational safety and running stability of the equipment by adopting safe voltage power supply and efficient current distribution system, providing a strong guarantee for the high-quality production of graphitized fibers.

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0014] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0015] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0016] In the description of the embodiments of the present invention, "plurality" means at least 2.

[0017] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] Example:

[0019] A graphitized fiber processing furnace,

[0020] Furnace body structure: The main body of the furnace 10 is made of high-strength carbon steel material, which has good high temperature resistance and mechanical strength, ensuring long-term stable operation in a high temperature environment.

[0021] Heating system: Heating resistors 20 are arranged in the upper part of the furnace body. These resistors are connected to the power supply through circuits. In order to meet the requirements of safe voltage, a 380V transformer is used to reduce the input voltage to 30-40V (preferred value). This voltage range is far lower than the safety voltage limit of the human body, effectively avoiding the risk of electric shock.

[0022] Power supply and current distribution system: The transformer 30 is connected to both ends of the heating resistor 20 through the insulated wires 40. These wires are safely introduced into the furnace through the openings on the stainless steel plate 11 in the middle of the furnace body 10. Considering the high power required by the heating resistor, the secondary current can reach a maximum of 8000A. In order to ensure the safety and efficiency of current transmission, 16 high-load-carrying cables are used to share this large current. Each cable is carefully designed and selected to ensure its long-term stable operation in a high-temperature environment.

[0023] Innovation:

[0024] Safe voltage application: For the first time, a safe voltage of ≤36V is used in the graphitized fiber processing furnace to supply power, which revolutionizes the risk of electric shock during operation and improves the safety of equipment use.

[0025] Efficient current distribution: Sharing high current through 16 cables not only ensures heating efficiency, but also effectively reduces the load of a single cable and extends the service life of the equipment.

[0026] Comprehensive material and design optimization: The comprehensive optimization of the furnace structure and heating system ensures that the equipment can operate stably and safely even under extremely high temperature conditions.

[0027] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
