Description

Technical Field

[0001] This utility model relates to the field of anti-magnetic field devices, and in particular to an anti-magnetic field device for use in on-site lighting fixtures for electrolytic aluminum. Background Technology

[0002] In the electrolytic aluminum production process, the electrolytic cell operates using a powerful direct current, and its working environment contains a continuous and strong direct current magnetic field with an intensity of several Tesla. Traditional lighting fixtures generally suffer from severe magnetic interference in this environment, manifesting as flickering lights, unstable brightness, or even abnormal blackouts, seriously affecting production safety and operational efficiency.

[0003] Existing antimagnetic lamps mostly use simple metal shielding structures, which are insufficient in shielding low-frequency strong magnetic fields. Moreover, after prolonged operation, the shielding body overheats due to the eddy current effect, leading to a shortened lamp life or reduced luminous efficiency. Conventional heat dissipation solutions rely solely on air convection or a single air-cooling system, which is insufficient to meet the heat dissipation requirements of the magnetic shielding components during continuous operation, especially under high heat load conditions where the heat dissipation efficiency drops sharply.

[0004] To address the aforementioned issues, this patent proposes a specialized antimagnetic lamp that integrates multi-layer magnetic shielding, composite heat dissipation, and protective structures to ensure reliable lighting in industrial settings with strong magnetic fields, such as those used in aluminum electrolysis.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To achieve the above-mentioned utility model objectives, such as Figures 1-4 As shown, this utility model provides an anti-magnetic field device for on-site lighting fixtures in electrolytic aluminum production. It includes a mounting base 1, with multiple protective connecting brackets 2 connected to the outer upper end of the mounting base 1. A heat dissipation cylinder 3 is connected to the upper end of each protective connecting bracket 2, and a shielding lamp cover 4 is connected to the upper end of the heat dissipation cylinder 3. A light bulb 5 is connected inside the shielding lamp cover 4, and the light bulb 5 is connected to the inner wall of the lower end of the shielding lamp cover 4 via a connecting base. A protective mirror 6 is installed inside the upper end of the shielding lamp cover 4, and multiple shielding frames 7 are connected to the outside of the shielding lamp cover 4. In electrolytic aluminum production sites, a magnetic field is generated under the influence of strong direct current. The light bulb 5 used in electrolytic aluminum production sites is prone to flickering and extinguishing under the interference of this magnetic field. At this time, the light bulb 5 can be protected by the anti-magnetic field device. The magnetic field of the field is shielded to ensure stable lighting of the bulb 5. The bulb 5 is installed inside the shielding lamp cover 4 through the lamp holder, and is connected to the mounting base 1 through the heat sink 3 and multiple protective connecting brackets 2. It is installed inside the production workshop through the mounting base 1. The shielding lamp cover 4 is made of a material with high magnetic permeability, such as ferrite, permalloy, amorphous alloy, etc. When the bulb 5 is interfered with by the magnetic field, the shielding lamp cover 4 and multiple shielding brackets 7 can absorb and block the magnetic field, thereby shielding the magnetic field and ensuring stable lighting of the bulb 5. The multiple protective connecting brackets 2 are located outside the multiple air-cooled fan blades 11, which can protect the multiple air-cooled fan blades 11 and prevent the multiple air-cooled fan blades 11 from being interfered with or damaged during rotation.

[0025] Preferably, a motor slot 8 is provided at the lower end of the heat dissipation cylinder 3, and a heat dissipation motor 9 is installed inside the motor slot 8. A motor shaft 10 runs vertically through the central axis of the heat dissipation motor 9. The motor shaft 10 is rotatably connected inside the heat dissipation motor 9. Multiple air-cooling fan blades 11 are connected to the lower side of the outside of the motor shaft 10, and the multiple air-cooling fan blades 11 are located in the middle position between the multiple protective connecting frames 2. During the process of shielding the magnetic field by the shielding lamp cover 4 and the multiple shielding frames 7, the shielding lamp cover 4 and the multiple shielding frames 7 will generate heat. At this time, the heat dissipation motor 9 drives the multiple air-cooling fan blades 11 to rotate through the motor shaft 10, and the rotation of the multiple air-cooling fan blades 11 generates upward cooling air. The cooling air blows upward onto the outer wall of the shielding lamp cover 4 and the multiple shielding frames 7, thereby cooling the shielding lamp cover 4 and the multiple shielding frames 7, avoiding the generation of heat inside the shielding lamp cover 4 and affecting the operation of the bulb 5, and ensuring the stable illumination of the bulb 5.

[0026] Preferably, a pump chamber 12 is provided on the upper side of the motor slot 8. The pump chamber 12 is located in the middle of the interior of the heat sink 3, and the upper end of the motor shaft 10 passes through the pump chamber 12. A spiral blade 13 is connected to the upper outer side of the motor shaft 10 and is rotatably connected to the interior of the pump chamber 12. Multiple heat dissipation fins 14 are connected to the lower outer side of the pump chamber 12 and are connected to the exterior of the heat sink 3. The connection between the heat dissipation fins 14 and the pump chamber 12 is located below the spiral blade 13. A liquid guide plate 15 is connected to the upper inner side of the heat dissipation fins 14, and an opening is left between the liquid guide plate 15 and the inner wall of the end of the heat dissipation fins 14 away from the heat sink 3. A heat absorption pipe 16 is connected to the upper end of the heat dissipation fins 14 near the heat sink 3. The heat absorption pipe 16 is located inside the shielding frame 7, and the other end of the heat absorption pipe 16 is connected to the upper outer side of the pump chamber 12. The cooling motor 9 drives multiple air-cooled fan blades 11 through the motor shaft 10. While rotating, the cooling motor 9 can drive the spiral blades 13 to rotate inside the pump chamber 12 via the motor shaft 10. Since the pump chamber 12, the cooling fins 14 and the heat absorption pipe 16 are all equipped with coolant, and the coolant inside the heat absorption pipe 16 can absorb the heat generated inside the shielding lamp cover 4 and the shielding frame 7, when the spiral blades 13 rotate inside the pump chamber 12, the spiral blades 13 drive the coolant inside the pump chamber 12 to flow downward, draw in the coolant inside the heat absorption pipe 16, and squeeze the coolant inside the lower side of the pump chamber 12 into the side of the cooling fins 14 near the heat sink 3. The coolant entering the cooling fins 14 flows away from the heat sink 3 under the obstruction of the liquid guide plate 15, and is cooled by the cooling fins 14 in the process. Finally, it flows back into the heat absorption pipe 16 through the cooling fins 14 on the upper side of the liquid guide plate 15 for circulation.

[0027] The coolant circulates within the pump chamber 12, heat dissipation fins 14, and heat absorption pipe 16 under the rotation of the spiral blades 13. During the flow, the coolant absorbs heat and cools the shielding lamp cover 4 and shielding frame 7. Then, it dissipates heat inside the heat dissipation fins 14. The heat dissipation fins 14 are also blown by cooling air, which improves the heat dissipation efficiency. This allows the anti-magnetic field device to be both air-cooled and water-cooled. The air cooling can also assist the water cooling in heat dissipation, improving the heat dissipation efficiency and ensuring the stable operation of the anti-magnetic field device and the stable illumination of the bulb 5.

[0028] The system employs a combination of air cooling and water cooling. The cooling motor 9 drives the air-cooled fan blades 11 to generate cooling airflow. At the same time, the spiral blades 13 push the coolant to circulate in the pump chamber 12, the heat dissipation fins 14, and the heat absorption pipes 16, achieving efficient heat exchange and preventing the shielding lamp cover 4 from overheating and affecting the lifespan of the bulb 5 and the stability of the lighting.

[0029] Multiple protective connecting brackets 2 serve as both support structures to fix the lighting fixtures and to protect the air-cooled fan blades 11 from external interference or mechanical damage, ensuring the long-term reliable operation of the device in harsh industrial environments.

[0030] Driven by the spiral blades 13, the coolant forms a forced circulation. The heat absorption pipe 16 absorbs heat inside the shielding frame 7 and dissipates heat quickly through the heat dissipation fins 14. Combined with air cooling, the overall heat dissipation performance is significantly improved, maintaining the stable operating temperature of the bulb 5 and the shielding cover 4.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
