Description

Technical Field

[0001] This utility model relates to the technical field of copper rod processing equipment, and in particular to an oxygen-free silver-containing copper rod processing device. Background Technology

[0002] Oxygen-free silver-containing copper rods are made from high-purity electrolytic copper as the base material, with the addition of a specific proportion of silver. They are manufactured through oxygen-free smelting, continuous casting, and rolling processes. Their core characteristic is extremely low oxygen content, effectively preventing the impact of oxidation impurities on conductivity. Therefore, they are mainly used in high-end wires and cables, electronic connectors, and other fields. During the processing of oxygen-free silver-containing copper rods, the lead rod needs to be pulled out of the crystallizer and cooled by natural heat dissipation or forced air cooling. Natural heat dissipation is inefficient, affecting production speed; while forced air cooling is more efficient, the airflow is easily affected by environmental interference, leading to uneven radial and axial cooling rates during the cooling process. This uneven cooling can cause internal stress concentration, coarse or uneven grain structure, and may lead to oxidation or defects on the surface of the rod, ultimately affecting the performance of the oxygen-free silver-containing copper rod. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a highly efficient and uniformly cooled oxygen-free silver-containing copper rod processing device.

[0004] This utility model discloses an oxygen-free silver-containing copper rod processing device, comprising a housing, cooling air rings, temperature monitoring components, a blower, a refrigeration unit, and a controller. Both ends of the housing have openings for the copper rod to pass through. Several cooling air rings are arranged inside the housing along the direction of the copper rod's travel. Each cooling air ring includes an annular air cavity surrounding the copper rod, with evenly distributed air outlets on the inner circumference of the annular air cavity. Each cooling air ring is connected to an independent air inlet pipe, and each air inlet pipe is equipped with an air inlet regulating valve. Monitoring components are installed in the area corresponding to each cooling air ring inside the housing. All air inlet pipes converge and connect to a distributor, which is connected to the output end of the refrigeration unit.

Detailed Implementation

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Reference Figures 1-3This embodiment provides an oxygen-free silver-containing copper rod processing device, including a housing 1, cooling air rings 2, temperature monitoring components 3, a blower 4, a refrigeration unit 5, and a controller 6. The housing 1 has openings 11 at both ends for the copper rod to pass through, providing a continuous passage for the copper rod. Inside the housing 1, several cooling air rings 2 are arranged along the direction of the copper rod's travel. Each cooling air ring 2 includes an annular air cavity 21 surrounding the copper rod, with evenly distributed air outlets 22 on the inner circumference of the annular air cavity 21. This surrounding design ensures that airflow is evenly distributed to the surface of the copper rod from all sides, thus avoiding uneven radial and axial cooling caused by unilateral or asymmetrical cooling methods. Each cooling air ring 2 is connected to an independent air inlet pipe 23, and each air inlet pipe 23 is equipped with an air inlet regulating valve 24, allowing for independent and precise control of the cooling intensity of each air ring. Temperature monitoring components 3 are installed in the area corresponding to each cooling air ring 2 within the housing 1 to monitor the surface temperature of the copper rod or the ambient temperature in that area in real time. The intake duct 23 ultimately connects to a distributor 7, which is connected to the output of the refrigeration unit 5 to distribute the cooled air to each branch. The output of the blower 4 is connected to the input of the refrigeration unit 5, providing power for the cooling airflow. The controller 6 is connected to the intake regulating valve 24, the temperature monitoring device 3, the refrigeration unit 5, and the blower 4, forming a closed-loop control system. During operation, based on the temperature data fed back by the temperature monitoring device 3, the controller 6 can dynamically adjust the opening of the intake regulating valve 24 of the corresponding cooling air ring 2, the airflow of the blower 4, and the cooling power of the refrigeration unit 5, thereby achieving precise and adaptive control of the copper rod cooling process. This ensures that the temperature change of the copper rod is gradual and uniform during the cooling process, preventing defects in the copper rod caused by uneven cooling, and improving the finished product quality and performance consistency of the oxygen-free silver-containing copper rod.

[0017] Specifically, the air outlet 22 of the cooling air ring 2 is set to be inclined at an angle relative to the radial direction of the copper rod. This inclined air outlet design means that when the cooling airflow impacts the surface of the copper rod, it not only has a radial cooling component, but also generates a tangential component along the axial direction of the copper rod. This tangential airflow can sweep away trace oxides or impurities that may be attached to the surface of the copper rod, while promoting the flow of air in the boundary layer of the copper rod surface, breaking the stagnant air film, and enhancing the heat exchange efficiency. The inclination angle can be set according to process requirements, preferably in the range of 10 degrees to 60 degrees, in order to balance the axial blowing force and the radial cooling effect.

[0018] Furthermore, along the direction of travel of the copper rod, the inclination angles of the air outlets 22 of the different cooling air rings 2 are set to be different; this method allows different airflow action modes to be used in different cooling stages to adapt to different process requirements; for example, in the initial cooling zone when the copper rod just enters the housing 1, a smaller inclination angle can be set to focus on stronger radial cooling to quickly reduce the surface temperature; in the intermediate cooling zone, a medium inclination angle can be set to balance cooling and purging; in the final cooling zone near the outlet, a larger inclination angle can be set to focus more on using axial airflow for final finishing and surface cleaning; through the gradient angle design, the cooling process is made more in line with the actual temperature drop and microstructure changes of the copper rod, which can optimize the overall cooling path and further improve cooling uniformity and product quality.

[0019] Reference Figure 4 The refrigeration unit 5 includes a compressor 51, a condenser 52, a throttling element 53, and an evaporator 54. These components are connected sequentially through refrigeration pipes to form a closed-loop refrigeration circuit. The compressor 51 compresses low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas. The high-temperature, high-pressure gas releases heat to the ambient medium in the condenser 52 and condenses into a high-pressure liquid. The high-pressure liquid is throttled and depressurized by the throttling element 53, becoming a low-temperature, low-pressure gas-liquid mixture. This mixture absorbs heat from the air supplied by the blower 4 in the evaporator 54 and evaporates into a low-temperature, low-pressure gas, thereby cooling the air. The cooled air is then transported to the distributor 7, and the evaporated refrigerant gas is drawn back into the compressor 51, completing the cycle. This active refrigeration method can provide a stable and temperature-controllable cooling medium, overcome the influence of ambient temperature fluctuations on the cooling effect, and ensure the stability and repeatability of the cooling process.

[0020] To ensure the cleanliness of the cooling air and prevent impurities from entering the refrigeration system or clogging the air outlet 22 of the cooling air ring 2, a filter assembly 8 is installed on the pipeline between the blower 4 and the refrigeration unit 5; refer to Figure 5The filter assembly 8 includes a filter cylinder 81, filter elements 82, and a first cover 83. The two ends of the filter cylinder 81 are sealed to the input end of the refrigeration unit 5 and the output end of the blower 4 via flanges or other means, ensuring that all airflow passes through the filter cylinder 81. Several filter elements 82 are arranged axially inside the filter cylinder 81. The filter elements 82 can be arranged in stages, such as a preliminary coarse filter and subsequent high-efficiency or medium-efficiency filters, to capture dust particles of different sizes in layers. A first operating port 84 corresponding to the position of the filter element 82 is opened on the side wall of the filter cylinder 81. The first cover 83 is movably installed on the first operating port 84 by bolts or a quick-opening mechanism and is equipped with a sealing ring to ensure airtightness. When it is necessary to replace or clean the filter element 82, simply open the first cover 83 for operation, making maintenance very convenient. The filter element 82 can be of various types, such as non-woven fabric, metal mesh, or activated carbon composite filter element, to adapt to different ambient air quality requirements.

[0021] Considering that the air cooled by the refrigeration unit 5 may carry moisture, directly blowing it onto the high-temperature copper rod could cause uncontrollable condensation due to localized overcooling or humidity changes. Therefore, a drying component 9 is also installed on the pipeline between the refrigeration unit 5 and the distributor 7; see reference. Figure 6 The drying assembly 9 includes a drying cylinder 91, a desiccant 92, and a second cover 93. The two ends of the drying cylinder 91 are respectively sealed to the output pipe of the refrigeration unit 5 and the input pipe of the distributor 7 to ensure that all airflow passes through the drying cylinder 91. The drying cylinder 91 is filled with a desiccant 92, such as silica gel, molecular sieve, or activated alumina, to adsorb moisture in the air and lower the dew point temperature of the cooling air. The side wall of the drying cylinder 91 is provided with a second operating port 94 for filling and replacing the desiccant 92. The second cover 93 is movably installed at the second operating port 94 and is provided with a sealing ring, which makes it easy to replace the desiccant 92 and ensures the continuity of the drying effect.

[0022] To ensure that the copper rod remains centered when passing through the housing 1 and to prevent it from swinging and coming into contact or rubbing against the cooling fan ring 2 or other internal components, guide positioning components 10 are provided inside the openings 11 at both ends of the housing 1. The guide positioning components 10 include several guide rollers 101 evenly distributed along the circumference of the copper rod. The guide rollers 101 are fixedly installed to the housing 1 by brackets. Their wheel surfaces are made of a material that is resistant to high temperatures and does not easily scratch the copper rod, and they form rolling contact with the outer wall of the copper rod. When the copper rod passes through, the guide rollers 101 rotate accordingly, which not only provides radial constraint and positioning for the copper rod, but also minimizes frictional resistance and potential damage to the surface of the copper rod.

[0023] To reduce heat exchange between the inside and outside of the enclosure 1, improve the stability of cooling efficiency, and reduce energy consumption, an insulation layer 12 is laid on the inner wall of the enclosure 1. The insulation layer 12 is made of a material with low thermal conductivity, such as rock wool, glass wool, polyurethane foam, or ceramic fiber blanket. The insulation layer 12 can block heat conduction between the cooling environment inside the enclosure 1 and the higher ambient temperature outside, maintain the temperature field stability of the cooling area inside the enclosure 1, prevent external heat from intruding and affecting the cooling effect, and also reduce the load on the refrigeration unit 5, thus achieving energy saving.

[0024] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
