Description

Technical Field

[0001] This utility model relates to the field of upward continuous casting technology, specifically a cooling device for an upward continuous casting unit. Background Technology

[0002] Oxygen-free copper rods are typically produced using the upward continuous casting method, which offers advantages such as high production efficiency and good production continuity. An upward continuous casting machine generally consists of a raw copper melting furnace, an upward continuous casting crystallizer, and a copper rod winding device. The upward continuous casting crystallizer uses vacuum negative pressure to draw molten copper from the melting furnace, and then a cooling device cools the solution inside the crystallizer, causing the molten copper to crystallize into solid copper, thus obtaining long, bright oxygen-free copper rods.

[0003] In existing technologies, circulating cooling typically uses a single cooling pipe spirally wound around the crystallizer. As the coolant continues to flow within the single pipe, the heat it absorbs accumulates continuously. As the heat dissipation path gradually lengthens due to the spiral winding, the cooling capacity of the coolant at the rear end is significantly reduced, making it difficult to cool the crystallizer evenly and efficiently, ultimately resulting in low overall cooling efficiency.

This addresses the problem that as the coolant continues to flow in a single pipe, the heat absorbed by it accumulates, and the heat dissipation path gradually lengthens due to spiral winding, resulting in a significant decrease in the cooling capacity of the coolant at the rear end, making it difficult to uniformly and efficiently cool the crystallizer, ultimately leading to low overall cooling efficiency.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-6This utility model discloses a cooling device for an upward continuous casting unit, including a crystallizer 1, and further including: a cooling pipe 2 sleeved on the crystallizer 1, the cooling pipe 2 being divided into multiple cooling chambers 3 by multiple partitions, a circulation device fixedly installed on the surface of the crystallizer 1, the circulation device being connected to each cooling chamber 3 by multiple connecting pipes 4 respectively; and a cooling continuous device inserted into the cooling pipe 2, the cooling continuous device being adapted to the number of cooling chambers 3, the cooling continuous device being used to extend the cooling effect of the coolant in the cooling chambers 3.

[0023] Specifically, the circulation device includes a water tank 5, a water pump 6, a water collection box 7, a return water pipe 8, and a refrigeration component. The water tank 5 is fixedly mounted on the surface of the crystallizer 1 by a bracket. The connecting pipe 4 is connected to the water tank 5 through a regulating valve. The refrigeration component is located inside the water tank 5. The water pump 6 is fixedly mounted on the surface of the water tank 5, and the outlet of the water pump 6 is connected to the water tank 5. The water collection box 7 is ring-shaped and fits onto the surface of the crystallizer 1. The water collection box 7 is fixedly connected to the bottom end of the cooling pipe 2. Each cooling chamber 3 is connected to the water collection box 7. One end of the return water pipe 8 is fixedly connected to the water collection box 7, and the other end of the return water pipe 8 is fixedly connected to the water inlet of the water pump 6.

[0024] In this embodiment, the water pump 6 is started, so that the coolant in the water tank 5 enters each cooling chamber 3 through multiple connecting pipes 4. The coolant in the cooling chamber 3 cools the solution in the crystallizer 1. After passing through the cooling chamber 3, the coolant enters the water collection box 7. Then, the water pump 6 pumps the coolant in the water collection box 7 back into the water tank 5 through the return water pipe 8 for cooling, thus achieving the effect of circulating cooling.

[0025] Specifically, the refrigeration component includes a heat exchange coil 9 and a stirring mechanism. The heat exchange coil 9 is fixedly installed inside the water tank 5. The heat exchange coil 9 is spiral-shaped and connected to an external refrigeration unit. The stirring mechanism is installed inside the heat exchange coil 9.

[0026] Specifically, the stirring mechanism includes a drive motor 10, a rotating rod 11, and a stirring blade 12. The rotating rod 11 is located inside the water tank 5, the stirring blade 12 is fixedly mounted on the surface of the rotating rod 11, the drive motor 10 is fixedly mounted on the outside of the water tank 5, and one end of the rotating rod 11 is fixedly connected to the output shaft of the drive motor 10.

[0027] In this embodiment, a low-temperature refrigerant is delivered to the heat exchange coil 9 by an external refrigeration unit. The heat exchange coil 9 cools the coolant inside the water tank 5. Then, the drive motor 10 is started, and the output shaft of the drive motor 10 drives the rotating rod 11 to rotate. The rotating rod 11 drives the stirring blade 12 to stir the coolant in the water tank 5, so that the coolant can fully contact the heat exchange coil 9 and improve the cooling effect of the coolant.

[0028] Specifically, the cooling device includes a cooling box 13 and a semiconductor cooling chip 14. The cooling box 13 is fixedly inserted into the cooling cavity 3. Both sides of the cooling box 13 are provided with connecting holes, and the cooling cavity 3 communicates with the connecting holes. The semiconductor cooling chip 14 is fixedly disposed on the surface of the cooling box 13.

[0029] In this embodiment, when the coolant flows into the middle of the cooling chamber 3, the coolant enters through the connecting hole on one side of the cooling box 13. Then, the semiconductor cooling chip 14 cools the coolant that has entered the cooling box 13 again, and then it flows out through the connecting hole on the other side, thereby stabilizing the temperature of the coolant and ensuring the uniform heat dissipation effect.

[0030] Specifically, multiple guide plates 15 are fixedly installed inside the refrigeration box 13, and two adjacent guide plates 15 are arranged crosswise. The guide plates 15 are used to divide the flow channels inside the refrigeration box 13 into an S-shape.

[0031] In this embodiment, the flow channel inside the cooling box 13 is divided into an S-shape by the guide plate 15 inside the cooling box 13, thereby extending the flow path of the coolant inside the cooling box 13 and thus improving the cooling effect.

[0032] Specifically, a heat-conducting plate 16 is fixedly disposed on the surface of the semiconductor cooling chip 14, and a heat sink 17 is fixedly disposed on the surface of the heat-conducting plate 16, with multiple heat sinks 17 arranged in an array.

[0033] In this embodiment, the heat-conducting plate 16 is fixedly disposed at the hot end of the thermoelectric cooler 14. The heat-conducting plate 16 conducts the heat on the thermoelectric cooler 14 to the heat sink 17, and the heat sink 17 dissipates the heat, thereby improving the cooling effect of the thermoelectric cooler 14.

[0034] The working principle and usage process of this utility model are as follows: During use, the lower end of the crystallizer 1 is immersed in the molten copper in the holding furnace, and its upper end is connected to a vacuum pump. After the air inside the crystallizer 1 is removed to create a negative pressure, the molten copper is slowly drawn into the crystallizer 1 under the influence of the negative pressure. To cool the solution inside the crystallizer 1, a low-temperature refrigerant is supplied to the heat exchange coil 9 through an external refrigeration unit. The heat exchange coil 9 cools the coolant inside the water tank 5. Then, the water pump 6 is started, allowing the coolant in the water tank 5 to enter each cooling chamber 3 through multiple connecting pipes 4. The coolant in the cooling chamber 3 cools the solution inside the crystallizer 1, causing the molten copper to cool. The coolant quickly solidifies into solid copper on its inner wall. As the traction mechanism operates, the solidified copper is continuously pulled upward to form a continuous oxygen-free copper rod. After passing through the cooling chamber 3, the coolant enters the water collection box 7. Then, the water pump 6 pumps the coolant in the water collection box 7 back into the water tank 5 through the return water pipe 8 for cooling, achieving a circulating cooling effect. When the coolant flows into the middle of the cooling chamber 3, it enters through the connecting hole on one side of the cooling box 13. Then, the semiconductor cooling chip 14 cools the coolant that has entered the cooling box 13 again, and then it flows out through the connecting hole on the other side, thereby stabilizing the temperature of the coolant and ensuring a uniform heat dissipation effect.
