Description

Technical Field

[0001] The utility model relates to the technical field of graphitization furnaces, in particular to an automatic power supply and transmission integrated system. Background Art

[0002] With the development of economy and the continuous changes in energy structure, AC graphitization furnaces are increasingly used in industrial production.

[0003] AC graphitization furnaces operate intermittently. A single production cycle involves loading, powering on, cooling, unloading, and overhauling, taking a total of 12 to 15 days, with powering on for only 3 to 5 days. Generally, one transformer can be used to power 5 to 7 furnaces of the same specifications, forming a furnace group, which is a production unit. During production, the transformer operates continuously, and the furnaces rotate. Typically, one furnace in a furnace group is energized, while the others are loading, cooling, loading and unloading, or undergoing overhaul. After one furnace completes operation, power is supplied to the next. A track is typically laid in front of each furnace group, and conductive equipment travels on the track, connecting the furnace head electrode to the busbar (aluminum busbar) of the furnace to be put into operation as needed. After heating is completed, the conductive equipment disconnects the furnace head electrode from the busbar and moves to the next furnace to be operated to connect the furnace head electrode and busbar.

[0004] Traditional power transmission technology for graphitization furnaces typically requires extensive manual intervention, which can lead to the following issues: Low efficiency: The need for manual operation limits the efficiency of the entire power transmission process. High instability: Errors or oversights in manual operation can affect the stability of the power supply. High safety hazards: Improper manual operation can cause safety issues such as short circuits and overloads. High maintenance costs: The need for regular maintenance and inspections results in high maintenance costs.

[0005] In order to solve the above technical problems, the present utility model designs an integrated system for automatic power supply and transmission. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and examples:

[0024] like Figure 1 and Figure 2As shown, an integrated system for automatic power supply and transmission is characterized by comprising a graphitization furnace 1, an aluminum bar 2, a material suction overhead crane 3, a conductive device 4, a rectifier transformer 5, a voltage-regulating transformer 6, a rectifier cabinet 7, and a control room 8. The graphitization furnace 1 is connected to the aluminum bar 2 via the conductive device 4. The ends of the aluminum bar 2 are connected to the rectifier transformer 5 and the voltage-regulating transformer 6. The rectifier cabinet 7 is connected to the rectifier transformer 5. The rectifier transformer 5, the voltage-regulating transformer 6, and the rectifier cabinet 7 are all connected to an oil-air cooler. The control room 8 comprises a controller 81 and a display screen 82. The material suction overhead crane 3, the rectifier transformer 5, and the voltage-regulating transformer 6 are all controlled by the controller 81. The graphitization furnace 1 is composed of multiple furnace groups. The aluminum bars 2 on both sides of the graphitization furnace 1 are gathered into a row and then connected to the rectifier transformer 5.

[0025] Oil-air coolers are a common transformer cooling method. They utilize air flow to remove heat from the transformer, thereby maintaining the transformer's operating temperature within a reasonable range. This cooling method can effectively increase the transformer's power capacity and service life. In power systems, transformers generate significant amounts of heat. If not dissipated promptly, the equipment can overheat, affecting performance and even causing damage.

[0026] The rectifier transformer 5 is equipped with a transformer oil-air cooler 51, and the voltage-regulating transformer 6 is equipped with a voltage-regulating oil-air cooler 61. This is because these two transformers have different functions and different load requirements. The rectifier transformer 5 is responsible for converting AC power into DC power, while the voltage-regulating transformer 6 is responsible for adjusting the voltage level. Their oil-air coolers can be customized according to their respective operating characteristics and load conditions to achieve the best cooling effect. In addition, the rectifier cabinet oil-air cooler 71 is connected to the rectifier cabinet 7. This is because the rectifier cabinet 7 itself also needs to dissipate heat, especially when it contains multiple rectifier units or other heat-generating components. The electronic components in the rectifier cabinet also generate heat during operation, so additional cooling facilities are required to ensure their normal operation.

[0027] The control room 8 is the command center of the entire system. It sends instructions to the suction crane 3 and other equipment through an automated control system such as a PLC. It also collects data from sensing devices, such as temperature, pressure, etc., for real-time monitoring and adjustment.

[0028] like Figure 3As shown, the aluminum bar 2 is a multi-piece aluminum bar, and the multi-piece aluminum bar is connected to an aluminum bar connector 21 at the bottom. The graphitization furnace 1 is provided with an electrode end 11, and the electrode end 11 is connected to the external graphite aluminum bar connector 12 after integration. Multi-piece aluminum bars have better heat dissipation performance than a single large aluminum bar. Due to the high thermal conductivity of aluminum, multi-piece aluminum bars can increase the heat dissipation area and speed up the heat conduction speed, thereby effectively reducing the temperature of the aluminum bar itself and preventing overheating. The function of the aluminum bar connector 21 and the graphite aluminum bar connector 12 is to connect the multi-piece aluminum bars to form a continuous conductive path. After the electrode end 11 is connected to the external graphite aluminum bar connector 12 after integration, it ensures that the current flows smoothly from the aluminum bar to the graphitization furnace 1. This connection method not only ensures good electrical conductivity, but also facilitates heat dissipation and improves the reliability of the system.

[0029] like Figure 4 As shown, the conductive device 4 is a conductive trolley equipped with two electrical connection plates, which are respectively connected to the aluminum bar connector 21 and the graphite aluminum bar connector 12. The conductive trolley can move on a track, which means that it can move with the position of the graphitization furnace 1 to ensure that it always maintains good contact with the graphitization furnace.

[0030] A drainage trough 10 is provided below the graphitization furnace 1. During operation of the graphitization furnace, condensed water or other liquids, such as coolant or process wastewater, may be generated. The drainage trough 10 can collect these liquids to prevent them from dripping directly onto the ground and causing environmental pollution or equipment corrosion.

[0031] The rectifier transformer 5 , the voltage regulating transformer 6 , the rectifier cabinet 7 and the controller 81 are connected via cables or busbars.

[0032] like Figure 5 As shown, the aluminum busbar 2 is connected to the conductive head 22. Copper flexible material 23 is used to connect the conductive head 22 to the rectifier transformer 5 and to the rectifier cabinet 7. The flexible material 23 exhibits a certain degree of flexibility and ductility, allowing it to adapt to relative displacement between devices, reducing the effects of mechanical stress on the connection and lowering the risk of loosening or breaking the connection due to vibration or thermal expansion. The flexible material 23 can withstand repeated bending and stretching, making it suitable for frequent operation or high-vibration environments and resistant to fatigue damage.

[0033] The AC power provided by the external power grid is first stepped down by a rectifier transformer 5 before entering a rectifier cabinet 7. Rectifier components within the rectifier cabinet 7 convert the AC power into DC power. A voltage-regulating transformer 6 adjusts the output voltage based on the actual needs of the graphitization furnace 1, ensuring a stable voltage supply to the graphitization furnace 1. The two power connection boards of the conductive device 4 are connected to the aluminum busbar connector 21 and the graphite aluminum busbar connector 12, respectively. The power is then transmitted to the various furnace heads of the graphitization furnace 1 via the aluminum busbar 2 and the conductive device 4. A material-collecting overhead crane 3 is installed above the graphitization furnace to facilitate the entry of raw materials into the furnace and the removal of finished products.

[0034] The control room 8 can control and monitor the power supply process to achieve accurate power supply to the products in the graphitization furnace.

[0035] This system can control the power of the graphitization furnace remotely or through pre-set settings, eliminating the need for on-site personnel supervision and achieving the effect of a dark factory. The system's main control equipment includes the material suction overhead crane 3, conductive equipment 4, rectifier transformer 5, voltage regulating transformer 6, rectifier cabinet 7, etc., and relies on various sensing devices such as temperature sensors, oil pressure sensors, limit switches, synchronous valves, and sequence valves to achieve precise power supply to the products in the graphitization furnace.

[0036] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
