Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing and processing technology, and in particular to water-cooling equipment for manufacturing high-temperature resistant electric heating cables for heavy oil extraction. Background Technology

[0002] The production of mineral-insulated cables requires a rigorous process to ensure product performance meets standards. First, the copper strip, which serves as the raw material for the outer sheath, undergoes strict cleaning to remove surface oil, impurities, and other contaminants, laying the foundation for subsequent processing. After cleaning, the copper strip enters the longitudinal wrapping process, where it is processed into a tubular structure using specialized equipment, forming the prototype of the cable's outer copper sheath. Subsequently, professional welding techniques are used to seal the joints, ensuring the integrity and airtightness of the copper sheath and preventing leakage of insulation materials or the entry of external impurities in subsequent processes. Next, magnesium oxide powder is filled into the copper sheath. The magnesium oxide powder must be filled evenly to ensure that the internal space of the copper tube is completely filled. Its core function is to serve as an insulating material for the internal battery core, isolating the battery core from the outer copper sheath, while also possessing good heat resistance and thermal conductivity. After filling, the filled copper cable is rolled to adjust the outer diameter and structural density of the cable to meet the design standards. After rolling, an annealing process is required, using high-temperature heating and slow cooling to eliminate the internal stress generated during cable processing, improve the mechanical properties and flexibility of the copper material, and enhance the overall stability of the cable. After the annealing process, the cable needs to be cooled in a water-cooling device to quickly reduce the cable temperature to a suitable range for subsequent processing. Finally, it is rolled to form a finished mineral-insulated cable that meets the specifications. In the production process of mineral-insulated cables, the cooling process after annealing is crucial. Currently, the industry generally uses water cooling. The specific operation of this cooling method is to pass the high-temperature cable through a square box filled with water, and the temperature is reduced by the heat exchange between the water flow and the surface of the cable. However, this water-cooling method has obvious drawbacks in practical applications. On the one hand, to ensure the cooling effect, water needs to be continuously supplied into the square box. However, since the cables need to enter and exit through the holes at both ends of the box, the water will continuously overflow from these holes, resulting in a large waste of water resources and increasing the water resource costs of production. On the other hand, a large amount of moisture will remain on the outside of the copper cables after water cooling. If this residual moisture is not removed in time and thoroughly, it will have an adverse effect on subsequent processing steps. For example, in subsequent rolling, packaging, or other surface treatment processes, residual moisture may cause oxidation, corrosion, and other problems on the surface of the cables, affecting product quality. At the same time, moisture may also affect the normal operation of processing equipment, increase equipment maintenance costs, and reduce production efficiency.

[0003] In summary, how to achieve cooling after cable annealing and improve the cooling effect has become an urgent problem for researchers in this field. Utility Model Content

[0005] Furthermore, the water spraying mechanism includes: a water pump installed on the water pumping pipe, and multiple spaced-apart branch pipes installed on the portion of the water pumping pipe above the copper cable. Each branch pipe is connected to a water spraying ring, and the copper cable passes through the center of the water spraying ring.

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0014] See Figure 1 This embodiment is a water-cooled device for manufacturing high-temperature resistant electric heating cables for heavy oil extraction. It includes a support frame 1, a cooling box 2, a water spraying mechanism 3, a circulating water tank 4, and a drying mechanism 5. The cooling box 2 is fixedly installed on the support frame 1. The circulating water tank 4 is located in a cool and ventilated place away from the cooling box 2. The water spraying mechanism 3 is installed on the cooling box 2 and is connected to the circulating water tank 4. The water spraying mechanism 3 draws out cold water from the circulating water tank 4 and sprays it onto the copper cables inside the cooling box 2 to cool them down. A return water pipe 6 is installed at the bottom of the cooling box 2. The other end of the return water pipe 6 is connected to the inside of the circulating water tank 4. A heat sink 7 is installed on the return water pipe 6. The drying mechanism 5 is installed on the support frame 1. The drying mechanism 5 is located below the heat sink 7 and draws in the air below it. The output part of the drying mechanism 5 is located on the left side of the cooling box 2 and blows air onto the cooled copper cables.

[0015] In this embodiment, the cooling box 2 is supported by the bracket 1. First, the copper cable is passed through the interior of the cooling box 2 from right to left, and then through the inner side of the spray section of the water spray mechanism 3. Then, the left end of the copper cable passes through the entire cooling box 2 and enters the subsequent rolling traction equipment, thereby pulling the copper cable to move in a straight line inside the cooling box 2. After the annealing process, the high-temperature copper cable enters the interior of the cooling box 2. At the same time, the operator manually activates the water spray mechanism 3 to draw out the cold water in the circulating water tank 4 and spray the copper cable in a ring to achieve water cooling. The sprayed water flows to the bottom of the inner side of the cooling box 2, and then flows back into the circulating water tank 4 through the return water pipe 6. Furthermore, the operator manually activates the drying mechanism 5 to draw airflow below the heat sink 7, allowing the heat sink 7 to cool the high-temperature water flow inside the return water pipe 6. The cooled water then flows back into the circulating water tank 4. The circulating water tank 4 has a large area and is located in a cool and ventilated place, ensuring that the water inside maintains a low temperature, thus maintaining the annealing effect on the high-temperature copper cables. At the same time, the drying mechanism 5 blows the drawn hot air onto the outside of the copper cables output from the cooling box 2 to dry them and remove water stains. This achieves the advantages of the device in cooling copper cables with circulating water, avoiding water overflow and waste, saving water, and drying the cooled copper cables for subsequent processing.

[0016] Please see Figure 1 , Figure 4 The water spraying mechanism 3 includes a water pump 31, a water pumping pipe 32, a diversion pipe 33, and water spraying rings 34 arranged at equal intervals. The water pump 31 is fixedly installed on the cooling box 2. The input end of the water pump 31 is connected to the interior of the circulating water tank 4 through the water pumping pipe 32. The output end of the water pump 31 is fixedly connected to the diversion pipe 33. The water spraying rings 34 are arranged at equal intervals inside the cooling box 2, and the top of the water spraying rings 34 extends through to the top of the cooling box 2 and is connected and fixed to the diversion pipe 33. The water spraying rings 34 are sleeved on the outside of the copper cable that has been quenched and entered the interior of the cooling box 2.

[0017] In this embodiment, the operator manually starts the water pump 31 to extract the cold water inside the circulating water tank 4 through the water pumping pipe 32, and then diverts it through the diversion pipe 33 to the inside of the spray ring 34. The spray ring 34 sprays water to fully cover the outside of the copper cable passing through it.

[0018] Please see Figure 1 , Figure 4 The water spray ring 34 has annularly distributed water spray holes 341 inside, which are arranged in annularly and vertically facing the outside of the copper cable.

[0019] In this invention, the water jets sprayed from the ring-shaped water jet holes 341 fully cover the outer side of the copper cable, ensuring a cooling effect.

[0020] Please see Figure 2 , Figure 3 The air drying mechanism 5 includes an exhaust fan 51, a connecting pipe 52, and a blower ring 53. The exhaust fan 51 is fixedly installed on the bracket 1 and is located below the heat sink 7. One end of the connecting pipe 52 is connected to the output end of the exhaust fan 51, and the other end of the connecting pipe 52 is connected and fixed to the blower ring 53. The blower ring 53 is sleeved on the outside of the copper cable output after cooling.

[0021] In this invention, the airflow below the heat sink 7 is drawn by manually starting the exhaust fan 51 and blown into the air blowing ring 53 through the connecting pipe 52. The air blowing ring 53 blows on the outer surface of the copper cable passing through it to achieve drying.

[0022] Please see Figure 2 The blower ring 53 has blower holes 531 arranged in a ring and converging to the right. With the converging arrangement of the blower holes 531, when the copper cable is pulled from right to left, the air blown out by the blower holes 531 can blow the water on the surface of the copper cable in the opposite direction, resulting in a better drying effect.

[0023] Please see Figure 1 The heat sink 7 has an internal cavity that communicates with the inside of the return water pipe 6. The bottom of the heat sink 7 is fixedly connected to a heat dissipation fin 71. The high-temperature water flow that returns passes through the internal cavity of the heat sink 7 and works with the heat dissipation fin 71 to dissipate heat. The exhaust fan 51 at the bottom draws the airflow at the bottom, which improves the contact efficiency between the heat dissipation fin 71 and the air and improves the heat dissipation effect.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
