Its stable operation directly affects the efficiency and quality of the entire industrial production. The electrode connection structure is the key part connecting the external power supply and the graphite heating field. Its performance also has a profound impact on the working state of the industrial furnace.

[0003] The traditional graphite heating field electrode connection structure of industrial furnaces is often simple in design and lacks flexibility. It usually adopts a relatively fixed connection method. The installation and disassembly between the electrodes and the connecting parts are extremely inconvenient. During long-term use, the electrodes are easily damaged or their performance degraded due to the influence of harsh working environments such as high temperature and current shock, and need to be replaced regularly. However, when replacing electrodes, the traditional connection structure requires a complex disassembly process, such as removing a large number of auxiliary fixing devices, carefully separating the electrodes and connecting lines, etc., and when reinstalling the new electrodes, it is necessary to accurately adjust the electrode position and connection tightness. A little carelessness may lead to poor electrode contact, affecting the heating effect and even causing safety accidents.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1:

[0024] Combine Figure 1-2The electrode connection structure for the graphite heating field of an industrial furnace shown in the figure includes an industrial furnace main body 1. The industrial furnace main body 1 serves as the basic framework of the entire industrial equipment. Its internal cavity has a specific spatial layout and structural design. On the inner wall of the cavity, a number of groups of graphite heating fields 2 are fixedly arranged through a stable and precise installation process. These graphite heating fields 2 are distributed in a specific arrangement according to the heating needs and process requirements of the industrial furnace. They are the key parts for realizing material heating treatment and can generate a high-temperature environment when powered on to meet the temperature conditions of various process operations such as material heating, smelting, and heat treatment in different industrial production processes. On the outer wall of the industrial furnace main body 1, several carefully planned and arranged The dry group electrode fixing component 3 is to ensure that it can stably and reliably assume the fixing and supporting functions of the subsequent electrode component 4. The electrode fixing component 3 is fixed with a matching electrode component 4 in a highly adaptive manner. This matching relationship is constructed based on multiple factors such as precise size design, mechanical structure association and electrical connection characteristics. One end of the electrode component 4 is tightly and efficiently connected to the graphite heating field 2 through a special connection method, thereby constructing a complete power transmission path, so that the external power supply can smoothly transmit electric energy to the graphite heating field 2, providing continuous and stable power support for its normal operation, thereby ensuring that the heating operation of the entire industrial furnace can be carried out in an orderly and efficient manner.

[0025] In this embodiment, the Figure 3 The electrode fixing assembly 3 shown plays an extremely critical supporting and connecting role in the entire electrode connection structure, and its specific composition is as follows: First, there is the flange 301, which is fixed on the outer wall of the industrial furnace body 1 in an extremely stable manner. During the installation process, the flange 301 and the outer wall of the industrial furnace body 1 are connected by high-strength means, such as using multiple high-strength bolts evenly distributed and tightened to ensure that the flange 301 can withstand greater pressure without loosening. On top of the flange 301, there is an insulating tube 302, the material of which has excellent insulation properties and can effectively prevent current from flowing in the electrode fixing assembly. 3 to prevent leakage or short circuit from occurring inside, thereby ensuring the electrical safety of the entire electrode connection structure. A locking wrench 303 is provided at the end of the insulating tube 302. When the electrode assembly 4 needs to be fixed or disassembled, the operator can rotate the locking wrench 303 to utilize its internal threaded structure or locking structure to achieve a tight connection or separation with the electrode assembly 4. The locking wrench 303 is flexible in rotation and has a certain resistance adjustment function. While ensuring that the electrode assembly 4 is firmly fixed, it is also easy to unlock when replacement is required, thereby providing a powerful operating tool support for rapid replacement.

[0026] In this embodiment, the Figure 4The electrode assembly 4 shown includes an electrode gasket tube 401, which is tightly sleeved inside the insulating tube 302. The matching accuracy between the two is extremely high, and the gap is controlled within a very small range to ensure that the electrode gasket tube 401 can be stable in the insulating tube 302 without shaking. There is an exquisite mechanical linkage matching relationship between the locking wrench 303 and the electrode gasket tube 401. A connector 402 is provided at one end of the electrode gasket tube 401. The shape and size of the connector 402 are carefully designed. It can achieve seamless docking with the graphite heating field 2 to ensure that electrical energy can be efficiently conducted from the electrode rod 404 to the graphite heating field 2, and has good sealing and stability at the connection part to prevent heat loss and current leakage. A fixing part 403 is provided at the other end of the electrode gasket tube 401, and an electrode rod 404 is provided in the cavity of the electrode gasket tube 401. A first locking bolt 405 for fixing the electrode rod 404 is provided on the fixing part 403. A second locking bolt 406 is also provided on one side of the power cord, and the second locking bolt 406 is used to ensure the reliability of its fixation when the power cord is subsequently connected.

[0027] In this embodiment, a sealing rubber ring 5 is carefully arranged at the connection between the insulating tube 302 and the electrode gasket tube 401. The sealing rubber ring 5 is made of a rubber material with excellent high temperature resistance, wear resistance and good elastic recovery performance, and can operate stably for a long time in the complex and harsh working environment of the industrial furnace. At the same time, the good elastic performance of the sealing rubber ring 5 can also compensate to a certain extent for the dimensional changes between the insulating tube 302 and the electrode gasket tube 401 due to thermal expansion and contraction. During the operation of the industrial furnace, due to the large temperature fluctuations, it can always maintain close contact with the two, maintain the stability of the sealing effect, and ensure the internal vacuum environment of the industrial furnace.

[0028] In this embodiment, a limiting protrusion 407 is provided on the outer wall of the electrode gasket tube 401. In terms of material, the limiting protrusion 407 is made of relatively high-strength material to withstand the frequent reciprocating motion of the electrode gasket tube 401 in the insulating tube 302 and the possible friction and collision. Functionally, the limiting protrusion 407 plays a crucial role in positioning and preventing it from being over-inserted or dislodged, thereby ensuring the reliability and stability of the connection between the electrode assembly 4 and the graphite heating field 21.

[0029] In this embodiment, a shrink tube 408 is provided between the electrode pad tube 401 and the fixing member 403 to avoid hard pulling due to some special reasons when the external power line is subsequently connected, thereby further ensuring the electrical safety of the electrode connection structure.
