Description

Technical Field

[0001] The utility model relates to the field of conductive trolleys, in particular to a conductive trolley for efficient power transmission of a graphitization furnace. Background Technique

[0002] A graphitization furnace is an industrial electric furnace mainly used for high-temperature heat treatment of carbon materials to convert them into graphite materials. During the graphitization process, non-graphitic carbon in the carbon materials is converted into graphitic carbon, thereby improving the electrical conductivity, thermal conductivity, corrosion resistance, lubricity and other properties of the materials.

[0003] Graphitization furnaces are commonly used in the production of products such as graphite electrodes, graphite crucibles, and special graphite, and are widely used in fields such as metallurgy, chemical industry, electronics, and new energy. A conductive trolley is a mobile device for conducting current. During the production process of a graphitization furnace, the conductive trolley is an important device for realizing power transmission.

[0004] However, when the existing conductive trolley is in use, it is not convenient to detect the temperature, current, and voltage of the conductive components in the conductive trolley. When the temperature, current, and voltage of the conductive components in the conductive trolley are abnormal, it is not conducive to timely discovery, which is not convenient for the safe and normal use of the conductive trolley and is not conducive to the use of the graphitization furnace.

[0005] Therefore, we propose a conductive trolley for efficient power transmission of a graphitization furnace. Content of the Utility Model

When the data information detected by the current sensor 12, the temperature sensor 13 and the voltage sensor 14 exceeds the preset value range on the PLC controller 15, the PLC controller 15 will turn on the buzzer alarm 16. When in use, it is convenient to detect the temperature, current and voltage of the conductive rod 10 in the main body 6 of the conductive trolley. If the temperature, current and voltage of the conductive rod 10 in the main body 6 of the conductive trolley are abnormal, it helps to timely detect the abnormality of the temperature, current and voltage of the conductive rod 10, so as to safely and normally use the main body 6 of the conductive trolley and the conductive rod 10, and helps to use the graphitization furnace.

[0033] Wherein, a conductive clip 11 is clamped on the outer side of the outer circumferential surface of the conductive rod 10 at one end far from the current sensor 12. A power transmission line electrically connected to an external graphitization furnace is installed on one side of the conductive clip 11 far from the main body 6 of the conductive trolley. One end of the conductive rod 10 far from the conductive clip 11 corresponds to the circuit interface of the external graphitization furnace. The conductive clip 11 helps to connect between the conductive rod 10 and the circuit interface of the external graphitization furnace; the current sensor 12 is electrically connected to the PLC controller 15, the temperature sensor 13 is electrically connected to the PLC controller 15, the voltage sensor 14 is electrically connected to the PLC controller 15, and the PLC controller 15 is electrically connected to the buzzer alarm 16. The PLC controller 15 helps to control the buzzer alarm 16.

[0034] The lower end of the current sensor 12 is in contact with the corresponding position on the conductive rod 10, the lower end of the temperature sensor 13 is in contact with the corresponding position on the conductive rod 10, and the lower end of the voltage sensor 14 is in contact with the corresponding position on the conductive rod 10. The temperature sensor 13 can detect the temperature on the conductive rod 10; a display screen 17 is installed in the middle of the surface of the main body 6 of the conductive trolley on the side close to the PLC controller 15.

The electric sliders 5 are slidably connected to the corresponding guide rails 4 in the horizontal direction. The guide rails 4 help to limit the electric sliders 5 and facilitate the stable movement of the electric sliders 5; connecting plates 7 are fixed on both sides of the middle of the lower surface of the main body 6 of the conductive trolley. A number of limiting wheels 8 are rotatably installed at intervals in the horizontal direction between the opposite surfaces of the connecting plates 7. A matching limiting groove 9 is provided on the middle of the upper surface of the fixing plate 3 corresponding to the limiting wheels 8. The connecting plates 7 help to limit the limiting wheels 8 and facilitate the use of the limiting wheels 8; mounting plates 1 are fixed on both side surfaces of the fixing plate 3. The mounting plates 1 are in a horizontal state. Bolts 2 are inserted vertically and threadedly in the middle of both ends of the mounting plates 1. The bolts 2 are in a vertical state and penetrate through the upper surface and the lower surface of the corresponding positions on the mounting plates 1. The bolts 2 can install and limit the mounting plates 1 and facilitate the use of the mounting plates 1.

[0036] The working principle of the present utility model is as follows: During use, the lower surface of the mounting plate 1 is aligned with the position in the external graphitization furnace where installation is required, such that the lower surface of the mounting plate 1 and the position in the external graphitization furnace where installation is required are in a matching and fitting state. Further, the mounting plate 1 and the position in the external graphitization furnace where installation is required are installed through bolts 2. The bolts 2 can fix and limit the mounting plate 1, facilitating the stable use of the mounting plate 1. The mounting plate 1 can support and limit the fixed plate 3 and various components assembled on the fixed plate 3, contributing to the stable use of the fixed plate 3 and various components assembled on the fixed plate 3.

[0037] When it is necessary to convert non-graphitic carbon in carbonaceous materials into graphitic carbon, the non-graphitic carbon is placed into the external graphitization furnace. Further, electricity is supplied to the graphitization furnace. When electricity needs to be supplied to the graphitization furnace, the electric slider 5 on the guide rail 4 is opened. The fixed plate 3 can limit the electric slider 5 through the guide rail 4, facilitating the stable movement of the electric slider 5. When the electric slider 5 moves, it can drive the conductive trolley body 6 to move away from the conductive clamp 11. When the conductive trolley body 6 moves, it can drive the conductive rod 10 to move horizontally. After the end of the conductive rod 10 away from the conductive clamp 11 is brought into contact connection with the circuit interface of the external graphitization furnace, the power transmission line, conductive clamp 11, conductive rod 10, and the circuit interface in the graphitization furnace are in a connected state, facilitating the supply of electricity to the graphitization furnace and contributing to the use of the graphitization furnace.

The current sensor 12, temperature sensor 13, and voltage sensor 14 can transmit the detected data information to the display screen 17. The display screen 17 can display the data information detected by the current sensor 12, temperature sensor 13, and voltage sensor 14, facilitating the observation of the data information detected by the current sensor 12, temperature sensor 13, and voltage sensor 14. The current sensor 12, temperature sensor 13, and voltage sensor 14 can transmit the detected data information to the PLC controller 15. When the data information detected by the current sensor 12, temperature sensor 13, and voltage sensor 14 exceeds the preset value range on the PLC controller 15, the PLC controller 15 will turn on the buzzer alarm 16. In the state where the buzzer alarm 16 is turned on, the buzzer alarm 16 can remind the staff, facilitating the staff to promptly discover abnormalities in the current, temperature, or voltage on the conductive rod 10 and contributing to the use of the conductive rod 10.

[0039] During the use process, in order to facilitate the detection of the temperature, current, and voltage of the conductive rod 10 in the conductive trolley body 6. When the temperature, current, and voltage of the conductive rod 10 in the conductive trolley body 6 are abnormal, it helps to promptly discover the abnormalities in the temperature, current, and voltage of the conductive rod 10, so as to safely and normally use the conductive trolley body 6 and the conductive rod 10, and helps to use the graphitization furnace.
