Description

Technical Field

[0001] This application relates to the technical field of submerged arc furnace transformers, and specifically provides a transformer for submerged arc furnaces. Background Art

[0002] A submerged arc furnace is also known as an electric arc furnace or a resistance furnace. It is mainly used for reducing and smelting raw materials such as ores, carbonaceous reducing agents, and solvents. Existing submerged arc furnace transformers generate a large amount of heat during operation. To ensure the use effect of the transformer, currently, heat sinks are mostly used for heat dissipation treatment.

[0003] For example, the patent with the application number CN202121795617.9 specifically discloses a submerged arc furnace transformer for electrofused magnesia. This submerged arc furnace transformer drives the coolant through the first heat dissipation pipe and the connecting pipe by the first water pump box to cool the first heat sink and the second heat sink on one side. The second heat sink cools the voltage transformation device, preventing the burning of the submerged arc furnace transformer caused by the poor heat dissipation effect of the original heat dissipation structure of the submerged arc furnace transformer using an axial flow fan, resulting in large current or insufficient cooling. It improves the quality and reliability of the submerged arc furnace transformer, and such a water-cooled cooling effect is better than that of forced air cooling, improving the service life and safety of the submerged arc furnace transformer.

[0004] During the use of the above patent, the transformer is cooled by heat sinks and water-cooling methods to achieve the purpose of transformer heat dissipation. However, when the above solution is used, it is not convenient to clean the heat sinks. During the long-term use of the transformer, dust and dirt will inevitably accumulate on the heat sinks.

Therefore, it is necessary to design a transformer for a submerged arc furnace to solve the above problems.

[0030] The moving mechanism 3 includes a fixing frame 301 provided on the transformer main body 1 and having an open end at one end, connecting blocks 302 symmetrically fixedly installed on both side surfaces of the transformer main body 1 and inserted into the fixing frame 301, a screw rod 303 rotatably connected to one side of the top of the fixing frame 301, two groups of guide rods 304 symmetrically fixedly installed on the top of the fixing frame 301, a movable frame 305 threadedly connected to the surface of the screw rod 303 and having the same shape as the fixing frame 301, and a motor 306 fixedly installed on one side of the bottom of the fixing frame 301.

[0031] Such as Figure 1 And Figure 2As shown in the figure, the heat dissipation mechanism 2 further includes mounting plates 202 symmetrically and fixedly installed on both sides of the transformer body 1 and located above the heat sinks 201, and a plurality of heat dissipation fans 203 provided on the mounting plates 202. Among them, a plurality of through holes are formed through the mounting plates 202, and the heat dissipation fans 203 are installed in the through holes;

[0032] As Figure 2 shown in the figure, two support beams 101 are symmetrically and fixedly installed at the bottom of the transformer body 1, and baffle plates 102 sleeved outside the heat sinks 201 are symmetrically and fixedly installed on both sides of the transformer body 1;

[0033] Working principle:

[0034] First, by placing the fixing frame 301 on the support beam 101 and moving the fixing frame 301 so that its end is inserted into the slot in the connection block 302, and then turning the hand-tightening bolt to fix the fixing frame 301, the purpose of installing the cleaning component 4 is achieved. Conversely, it can be disassembled to facilitate regular maintenance of the cleaning component 4;

[0035] Secondly, during the use of the transformer body 1, the heat is transferred to the outside through the heat sinks 201 for heat dissipation, and at the same time, the heat dissipation fans 203 are used to blow air to quickly cool down the heat sinks 201, so as to achieve the effect of dissipating heat from the transformer body 1;

[0036] Finally, when cleaning the heat sink 201, the motor 306 drives the screw 303 to rotate, causing the movable frame 305 to drive the two fixing plates 4011 to move upward along the surface of the guide rod 304. At the same time, the pump body 4022 extracts the cleaning agent in the liquid storage tank 4021 and inputs it into the atomizing nozzle 4024 through the connecting pipe 4023 for atomizing and spraying. As the fixing plate 4011 moves, the surface of the heat sink 201 is evenly sprayed with the cleaning agent. At the same time, the transformer body 1 is shielded and protected by the baffle plate 102 to prevent the cleaning agent from accidentally entering the inside of the transformer body 1. After moving above the heat sink 201, the spraying and movement stop. After the cleaning agent dissolves the stubborn stains, the motor 306 drives the screw 303 to reverse again, causing the fixing plate 4011 to move downward. At the same time, the electromagnet 4016 is energized and repels the magnet sheet on the moving plate 4014 with the same pole, causing the moving plate 4014 to drive the cleaning cotton plate 4015 to move into contact with the heat sink 201. As the fixing plate 4011 moves, the heat sink 201 is wiped by the cleaning cotton plate 4015. After moving to the bottom of the heat sink 201, the movement stops. At the same time, the electromagnet 4016 changes the magnetic pole to adsorb the moving plate 4014, causing the cleaning cotton plate 4015 to move into the housing 4013. Then, the heat sink 201 is quickly dried by the blowing of the heat dissipation fan 203. Therefore, the effect of cleaning the dust and stains attached to the surface of the heat sink 201 is achieved. After cleaning, the fixing plate 4011 can be detached, and the housing 4013 is moved to drive the limit slider 4012 to separate from the fixing plate 4011 to clean and maintain the cleaning cotton plate 4015.

[0037] It should be noted that: to ensure safety, when cleaning and maintaining the heat sink 201, the power supply of the transformer body 1 can be cut off and grounded to avoid any potential safety risks. In addition, the motor 306, the electromagnet 4016, and the pump body 4022 in this device are all controlled externally to achieve an automated effect, which is well-known prior art to those skilled in the art and will not be elaborated here. In addition, the electrical components of this device are powered by an external power supply, separate from the power supply of the transformer body 1.

[0038] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
