Abstract
Description
Technical Field
[0001] This utility model relates to the field of submerged arc furnace technology, specifically a new type of large conductive copper tile for submerged arc furnaces. Background Technology
[0002] Large conductive copper tiles for submerged arc furnaces are mainly used to hold electrodes and transmit large currents, making them a key component in processes such as ferroalloy smelting. Their excellent conductivity and high-temperature resistance ensure stable operation and efficient smelting of the submerged arc furnace.
[0003] In the current use of conductive copper tiles, electrodes are usually directly inserted into one side of the conductive copper tile. Due to the high temperature in the electric arc furnace and the instability of the current inside the electrode, the electrode is prone to falling off or making poor contact during insertion, which affects the efficiency of use.
[0004] Therefore, those skilled in the art have provided a novel large conductive copper tile for submerged arc furnaces to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a new type of large conductive copper tile for electric arc furnaces to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A novel large conductive copper tile for a submerged arc furnace includes a copper tile body. A connecting sleeve is fixedly connected to the top of the copper tile body. The top of the connecting sleeve has an insertion interface. A limiting mechanism is provided on the outside of the connecting sleeve. The limiting mechanism includes a limiting hole, which is located on the inner wall of the connecting sleeve. A fixed chuck is inserted into the limiting hole. A push rod is connected through the middle of the fixed chuck. A telescopic spring is wobbly connected to the outside of the push rod. A locking block is fixedly connected to one end of the push rod, and a fixing member is threaded to the other end of the push rod. By installing the limiting mechanism, when the connecting joint is inserted into the insertion interface, rotating or pushing the fixing member causes the push rod to move the locking block into the limiting hole. The telescopic spring is compressed, and the locking block can fix the connecting joint, preventing it from loosening or falling off. Because the locking block and the push rod have a certain degree of elasticity, they can adapt to connecting joints of different sizes and shapes, thereby improving the stability and flexibility of the copper tile in use.
[0008] As a further embodiment of this utility model: a connecting connector is inserted into the inside of the plug interface, an electrode wire is fixedly connected to one side of the connecting connector, and a fixing ring is sleeved on the outside of the electrode wire. The plug interface, connecting connector, electrode wire, and fixing ring cooperate with each other to form a conductive connection system between the copper tile and the electrode. The use of the connecting connector can fix the electrode wire and prevent it from falling off during use, thus affecting the stability of the connection.
[0009] As a further improvement of this utility model: the copper tile body is provided with cooling pipes inside, the cooling pipes are distributed in a U-shape, a water inlet is opened on one side of the copper tile body, the internal pipe of the water inlet is connected to a sealing ring, and a sealing cover is rotatably connected inside the sealing ring. The U-shaped cooling pipe design allows the cooling water to circulate inside the copper tile body, thereby distributing the cooling effect more evenly and improving the cooling efficiency.
[0010] As a further improvement of this utility model: the cooling pipe is externally clamped with multiple clamping blocks, and a support plate is fixedly connected to one side of each clamping block. Through the cooperation of the clamping blocks and the support plate, the cooling pipe can be fixedly supported, preventing it from shifting or deforming due to vibration or temperature changes during operation, thereby enhancing the overall structural strength of the copper tile and improving its vibration and impact resistance.
[0011] As a further improvement of this utility model: an insulating block is fixedly connected to one side of the copper tile body, an installation block is fixedly connected to one side of the insulating block, and a fastening block is fixedly connected to one side of the installation block. Through the cooperation of the installation block and the fastening block, the insulating block can be fixedly connected to one side of the copper tile body, preventing the copper tile body from loosening and causing the insulating block to fall off, thereby causing electrical short circuit, leakage or other potential safety hazards.
[0012] As a further embodiment of this utility model: a connecting seat is fixedly connected to the bottom of the copper tile body, and a connecting port is opened on the surface of the connecting seat. A connecting block is inserted into the connecting port. The connecting seat serves as a fixing component at the bottom of the copper tile body, providing a stable foundation for the connection of the copper tile with other equipment or components. It ensures the correct position of the copper tile in the electric arc furnace and allows for reliable connection with other components.
[0013] As a further improvement of this utility model: a temperature detection block is sleeved on the outside of the connecting sleeve, and a pressure detection gauge is provided on the top of the temperature detection block. A protective layer is provided on the outside of the temperature detection block and the pressure detection gauge. By integrating temperature and pressure detection functions, the equipment can monitor and adjust the working parameters in real time, which can avoid equipment failure or safety accidents caused by excessive temperature and improve the overall safety of the equipment.
[0014] As a further improvement of this utility model: the top of the side of the copper tile body that contacts the electrode is provided with an anti-jamming chamfer, and connecting plates are fixedly connected to both sides of the copper tile body.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. By installing a limiting mechanism, when the connector is inserted into the socket, the push rod can be rotated or pushed to move the locking block into the limiting hole by rotating or pushing the fixing part. The telescopic spring is compressed, and the locking block can fix the connector, preventing the connector from loosening or falling off. Since the locking block and push rod have a certain degree of elasticity, they can adapt to connectors of different sizes and shapes, thereby improving the stability and flexibility of the copper tile in use.

A sealing cover 11 is rotatably connected inside the sealing ring 10. Multiple clips are clamped to the outside of the cooling pipes 8. A support plate 13 is fixedly connected to one side of each of the multiple snap-fit blocks 12. An insulating block 14 is fixedly connected to one side of the copper tile body 1. An mounting block 15 is fixedly connected to one side of the insulating block 14. A fastening block 16 is fixedly connected to one side of the mounting block 15.

The connecting joint 5 is then connected to the connecting sleeve 2 through the insertion interface 3, ensuring a stable connection between the electrode wire 6 and the copper tile body 1. The connecting joint 5 is inserted into the inside of the insertion interface 3. Through the cooperation between the push rod 403 and the telescopic spring 404, the electrode wire 6 is inserted into the inside of the insertion interface 3. The locking block 405 clamps and secures the connecting joint 5, while simultaneously introducing cooling water through the water inlet 9, allowing the added cooling water to flow through the cooling pipe 8 and form a circulating cooling system inside the copper tile body 1.

[0026] Example 2
[0027] Reference Figure 1-3This embodiment is based on the previous embodiment, but differs in that a connecting seat 17 is fixedly connected to the bottom of the copper tile body 1.

Connecting plates 24 are fixedly connected to both sides of the copper tile body 1. The copper tile body 1 serves as an electrode... The electrode system is a crucial conductive component that transfers current from the electrode to other parts of the submerged arc furnace, enabling the conversion and utilization of electrical energy. Temperature detection block 20 monitors the temperature of the copper tile body 1 in real time; if the temperature is too high, it may trigger an alarm or automatically shut down to prevent equipment damage. Pressure gauge 21 monitors the pressure exerted on the copper tile body 1, ensuring it operates within safe limits. The design of the protective layer 22 and connecting structure also contributes to heat dissipation and maintains equipment stability. Anti-jamming chamfer 23 effectively prevents the electrode shell protrusion from getting stuck on the upper edge of the copper tile, avoiding the risk of the copper tile slipping or the lifting lug breaking. Meanwhile, the connecting structures such as connecting seat 17, connecting block 19, and connecting plate 24 also ensure the stability and safety of the copper tile.
