[0002] During the copper wire drawing process, intense frictional heat and deformation heat are generated between the copper wire and the drawing die, causing the temperature of the drawing fluid to rise sharply. High temperatures not only reduce the lubrication performance and cooling effect of the drawing fluid, accelerate its aging and the formation of mud (mainly composed of copper powder), but also affect the surface quality and dimensional accuracy of the copper wire, and shorten the service life of both the drawing fluid and the drawing die.

[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0027] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.
[0028] Reference Figures 1-8 This embodiment provides a drawing fluid supply device with circulating cooling and heating functions, which includes a liquid tank unit 100. The liquid tank unit 100 is provided with an isolation member 101, which separates the internal space of the liquid tank unit 100 to form a sedimentation chamber A1 and a discharge chamber A2.
[0029] This partitioned design allows the drawing fluid to first settle impurities in the settling chamber A1 before entering the discharge chamber A2 for further treatment. This can quickly separate large particles of impurities in the drawing fluid, avoid impurities interfering with temperature control and subsequent circulation, effectively improve the cleanliness of the drawing fluid, extend its service life, and the rationally divided chamber structure can adapt to the step-by-step needs of drawing fluid purification and circulation, taking into account both practicality and stability.
[0030] The liquid tank unit 100 is equipped with a heat exchange component 200 for changing the temperature of the drawing fluid. The drawing fluid flows sequentially through the first chamber A1 and the second chamber A2. The heat exchange component 200 can precisely adjust the temperature of the drawing fluid, ensuring that it is always within the optimal process range of 35℃ to 45℃, thus guaranteeing the lubrication and cooling effect and the quality of the copper wire.
[0031] The design of the drawing fluid flowing through two chambers in sequence enables step-by-step processing of "sedimentation + temperature control", which avoids unprecipitated impurities adhering to the surface of the heat exchange components and affecting the heat exchange efficiency. In addition, while ensuring that impurities are fully precipitated, the drawing fluid is uniformly temperature controlled, ensuring that the drawing fluid entering the subsequent circulation is both clean and at a suitable temperature, effectively improving production stability.
[0032] Specifically, at least two sets of liquid tank units 100 are arranged side by side, namely a primary liquid tank 100a and a secondary liquid tank 100b.
[0033] The two-stage series liquid tank design enables graded sedimentation and deep purification of the drawing fluid. The first-stage liquid tank 100a focuses on removing large particulate impurities, while the second-stage liquid tank 100b further traps fine particulate impurities. This dual purification can reduce the copper powder content by more than 50%, significantly improving the cleanliness of the drawing fluid. At the same time, the two-stage liquid tanks can work independently, facilitating maintenance without interrupting production, effectively improving production continuity, and meeting the needs of industrialized mass production.
[0034] Furthermore, the isolation components 101 are fixed in the middle of the primary liquid tank 100a and the secondary liquid tank 100b, respectively, serving as the primary isolation plate 101a and the secondary isolation plate 101b.
[0035] Fixing the isolation plate in the middle of the liquid tank allows the sedimentation chamber A1 and the discharge chamber A2 to form a reasonable volume ratio, ensuring that the sedimentation chamber A1 has enough space for impurities to settle, while the discharge chamber A2 can hold a sufficient amount of clean drawing liquid to meet the circulation requirements.
[0036] Furthermore, the plate-shaped isolation component 101 has a stable structure and good separation effect, which can accurately adapt to the graded treatment requirements of the two-stage liquid tank. At the same time, the isolation plate 101 can serve as the installation carrier for the heating element of the heat exchange component 200, effectively saving the internal space of the liquid tank. Moreover, it is made of corrosion-resistant steel plate and fixed by welding, which can avoid leakage caused by the corrosion of the wire drawing liquid, and further extend the overall service life of the equipment.
[0037] Furthermore, the sedimentation chamber A1 and the discharge chamber A2 in the primary liquid tank 100a are respectively the first sedimentation chamber A11 and the first discharge chamber A21, and the sedimentation chamber A1 and the discharge chamber A2 in the secondary liquid tank 100b are respectively the second sedimentation chamber A12 and the second discharge chamber A22.
[0038] Clearly distinguishing and naming the chambers of the two-stage liquid tank can clearly define the functional boundaries of each chamber, achieve precise positioning of the chamber functions, and ensure that the drawing fluid flows in an orderly manner in the order of "primary sedimentation - primary discharge - secondary sedimentation - secondary discharge". At the same time, it facilitates the targeted cleaning of impurities in each chamber by the staff, reduces the workload of maintenance, improves maintenance efficiency, and also provides convenience for subsequent pipeline connection and system debugging.
[0039] The first discharge chamber A21 is connected to the second sedimentation chamber A12. The connection between the two chambers enables the orderly flow of the drawing liquid between the two liquid tanks, allowing the drawing liquid purified by the first sedimentation to smoothly enter the second liquid tank for further treatment. This avoids the mixing of the clean drawing liquid in the first liquid tank with the untreated impurity-containing drawing liquid, thus ensuring the purification effect.
[0040] Meanwhile, the flow can be completed without additional power, which simplifies the system structure, reduces energy consumption, and ensures that most impurities have been removed from the drawing liquid entering the secondary liquid tank 100b, providing a good foundation for secondary sedimentation and subsequent temperature control, and further improving the overall processing effect.
[0041] The heating element of the heat exchange assembly 200 includes a heating rod 201, which is fixedly installed inside the primary isolation plate 101a and the secondary isolation plate 101b. The heating rod 201 can quickly preheat the drawing fluid, ensuring that the equipment can start smoothly in the low temperature environment of -35℃ in northern winters. At the same time, it can achieve uniform heating of the drawing fluid, maintain its suitable viscosity, effectively expand the application range of the equipment, and adapt to different climate conditions in the north and south. Fixing the heating rod inside the isolation plate, thanks to the advantage of the isolation plate being located in the middle of the liquid tank, can make the heating heat evenly diffuse to the entire liquid tank, avoid local overheating that causes the drawing fluid to age, and balance the heating effect and the service life of the drawing fluid.
[0042] Furthermore, there is a height difference between the primary isolation plate 101a and the secondary isolation plate 101b and the top of the primary liquid tank 100a and the secondary liquid tank 100b, and an overflow port B is formed at the top of the primary isolation plate 101a and the secondary isolation plate 101b. The overflow port B connects the first sedimentation chamber A11 and the first discharge chamber A21, as well as the second sedimentation chamber A12 and the second discharge chamber A22.
[0043] Overflow port B relies on the height difference to form a natural overflow, requiring no additional power. It can achieve flow by relying on the liquid level difference of the drawing fluid itself. This not only avoids the sedimented impurities being agitated again, ensuring sufficient sedimentation, but also further separates impurities floating on the surface during the overflow process, improving the cleanliness of the drawing fluid. At the same time, the structure is simple and easy to maintain, which can effectively reduce the system failure rate and improve the stability and reliability of equipment operation.
[0044] The first discharge chamber A21 and the second sedimentation chamber A12 are connected by a filter tube 102. The filter tube 102 can achieve further filtration during the flow of the drawing liquid, effectively intercepting a small amount of fine particulate impurities remaining in the drawing liquid in the first discharge chamber, and further improving the cleanliness of the drawing liquid. At the same time, as a flow channel for the drawing liquid between the two liquid tanks, its structural design can ensure smooth flow, avoid leakage or stagnation of the drawing liquid, provide a guarantee for the continuous operation of graded purification, and take into account both filtration effect and flow stability.
[0045] The filter tube 102 includes a horizontal connecting tube 102a and a first vertical tube 102b and a second vertical tube 102c that are vertically connected at both ends. The top openings of the first vertical tube 102b and the second vertical tube 102c are respectively located in the first discharge chamber A21 and the second sedimentation chamber A12. The combination structure of "horizontal connecting tube + vertical tube" can realize vertical liquid extraction and horizontal flow of the drawing liquid, effectively prevent impurities at the bottom of the discharge chamber from being sucked into the filter tube, and at the same time facilitate the control of the flow rate of the drawing liquid.
[0046] The design of the top openings of the first vertical pipe 102b and the second vertical pipe 102c allows for priority extraction of clean drawing fluid from the upper part of the discharge chamber, reducing the entry of impurities. At the same time, it facilitates the observation of the flow status of the drawing fluid by the staff, and allows for quick troubleshooting and handling if blockage occurs. The structure is simple and practical, reducing the difficulty of maintenance.
[0047] In this embodiment, the length of the first vertical pipe 102b is greater than that of the second vertical pipe 102c, and a one-way valve 102a-1 is fixed in the middle of the horizontal connecting pipe 102a. The first vertical pipe 102b being longer than the second vertical pipe 102c can form a liquid level difference of 20cm to 25cm. The natural filtration and flow of the drawing liquid can be achieved by relying on gravity, without the need for an additional pump. This can save energy and reduce consumption, and also avoid the agitation of impurities caused by forced drive, ensuring continuous and stable filtration.
[0048] The one-way valve 102a-1 can effectively prevent the drawing fluid in the secondary liquid tank 100b from flowing back to the primary liquid tank 100a, avoiding contamination of the deeply purified drawing fluid, ensuring that the two-stage purification effect is not lost, and the one-way valve has a simple structure and low failure rate, which can further reduce equipment maintenance costs.
[0049] The heat exchange assembly 200 also includes a cooling tank 202, a cooling pipe 203 and a refrigerator 204. The cooling pipe 203 is independently arranged on the circumferential inner wall of the primary liquid tank 100a and the secondary liquid tank 100b.
[0050] The cooling assembly has high overall cooling efficiency, which can quickly cool the high-temperature drawing fluid to the optimal process range of 35℃~45℃, effectively delaying the aging of the drawing fluid. The cooling pipes 203 are independently arranged on the inner wall of the two-stage liquid tank, which can increase the contact area between the cooling pipes 203 and the drawing fluid, realize staged cooling, avoid uneven cooling caused by excessive single-stage cooling load, effectively reduce liquid temperature fluctuation, improve temperature control accuracy, and the independent arrangement of cooling pipes facilitates individual maintenance and replacement, reducing maintenance workload.
[0051] The inlets of both sets of cooling pipes 203 are connected to the liquid inlet pipe 203a, and the outlets are connected to the liquid outlet pipe 203b. This centralized connection method can realize the centralized supply and recovery of cooling water, ensuring that the cooling water flow and pressure in the cooling pipes of the two-stage liquid tanks are consistent, thereby making the cooling effect of the drawing fluid in the two-stage liquid tanks uniform and ensuring the temperature stability of the drawing fluid; at the same time, it can simplify the pipeline connection, reduce the risk of pipeline leakage, provide convenience for system debugging and daily maintenance, and improve the reliability of equipment operation.
[0052] Furthermore, the liquid outlet pipe 203b is also connected to the inlet of the internal pipeline of the chiller 204, and the outlet of the internal pipeline of the chiller 204 is also connected to the drain pipe 204a. The chiller can quickly cool down the cooling water that has heated up after absorbing the heat of the drawing liquid, ensuring that the cooling water always maintains a good cooling effect. Its rated cooling capacity of 30kW can meet the cooling needs under high temperature and high load conditions.
[0053] Meanwhile, this pipeline connection method enables closed-loop recycling of cooling water, eliminating the need for frequent replenishment of new cooling water. This not only saves water resources but also prevents excessively high cooling water temperatures from affecting the temperature control accuracy of the drawing fluid, ensuring stable cooling performance.
[0054] Furthermore, a water supply pump 202a is fixed on the cooling tank 202. The inlet of the water supply pump 202a is connected to a liquid extraction pipe 202a-1, and the outlet is connected to an inlet pipe 203a. The water supply pump 202a provides stable power for the closed-loop circulation of cooling water, ensuring smooth flow of cooling water from the cooling tank 202 to the cooling pipe 203 and the refrigerator 204, and the flow rate is controllable, effectively improving cooling efficiency. The cooperative design of the liquid extraction pipe 202a-1 and the inlet pipe 203a allows the liquid extraction pipe 202a-1 to extend into the interior of the cooling tank 202, fully extracting cooling water and avoiding residual cooling water in the cooling tank 202, further improving the utilization rate of cooling water and balancing power supply and resource conservation.
[0055] The cooling box 202 is divided by a partition plate 202b, which separates the internal chambers of the cooling box 202 to form a stationary chamber B1 and a discharge chamber B2. The liquid extraction pipe 202a-1 extends below the liquid level of the coolant in the stationary chamber B1, and the liquid discharge pipe 204a is located above the liquid level of the coolant in the discharge chamber B2.
[0056] The compartmentalized design allows the cooling water returning from the chiller 204 to first settle in the discharge chamber B2 before flowing into the settling chamber B1 through the connecting hole. This process helps to settle impurities and eliminate air bubbles, effectively purifying the cooling water, preventing impurities from clogging the cooling pipe 203, and extending the service life of the cooling pipe 203. At the same time, eliminating air bubbles can improve the heat exchange efficiency of the cooling pipe 203, ensuring stable cooling performance and providing a guarantee for overall temperature control.
[0057] The partition plate 202b has a connecting hole 202b-1 in the middle. The connecting hole enables the flow of cooling water between the discharge chamber B2 and the stationary chamber B1, allowing the purified cooling water to smoothly enter the stationary chamber B1 for the water supply pump to draw and circulate, ensuring the continuity of cooling water circulation.
[0058] The connecting hole 202b-1 is located in the middle of the partition plate, which can effectively control the flow rate of cooling water and prevent the sedimented impurities from being stirred up again due to excessive flow rate. At the same time, it ensures that the cooling water discharged into the cavity B2 can flow into the settling cavity B1 slowly and evenly, so as to fully realize the sedimentation of impurities and the elimination of air bubbles, and further improve the cleanliness of cooling water.
[0059] Furthermore, the bottom of the second discharge chamber A22 of the secondary liquid tank 100b is connected to the lubrication point inside the copper wire drawing machine 300 via the liquid supply pipe 301. The second discharge chamber A22 is the final chamber after the drawing liquid has completed the classification sedimentation, deep purification and precise temperature control. The drawing liquid at the bottom of it is the cleanest and has the most uniform temperature, and it can effectively prevent floating dust and impurities at the top of the chamber from entering the liquid supply pipe.
[0060] By directly connecting the liquid supply pipe 301 to the lubrication point 300 of the copper wire drawing machine, clean and appropriately temperatured drawing fluid can be precisely supplied to the parts that require lubrication and cooling, directly improving the lubrication and cooling effect during the copper wire drawing process, reducing problems such as scratches on the copper wire surface and dimensional deviations, and effectively improving product quality.
[0061] The waste liquid pool of the copper wire drawing machine 300 is connected to the top of the first sedimentation chamber A11 of the primary liquid tank 100a through the return liquid pipe 302. The return liquid pipe 302 is connected to the top of the first sedimentation chamber A11 of the primary liquid tank 100a, which allows the waste wire drawing liquid to flow slowly into the sedimentation chamber after use, avoiding excessive impact force that agitates the already settled impurities. At the same time, it facilitates the waste wire drawing liquid to settle fully in the sedimentation chamber, laying the foundation for subsequent graded purification.
[0062] The connection design with the waste liquid pool enables rapid recycling of waste drawing liquid, avoiding waste and environmental pollution. At the same time, it allows the waste drawing liquid to enter the purification process in a timely manner, achieving recycling and effectively reducing production costs.
[0063] The height of the outlet of the return pipe 302 is lower than the height of the inlet connected to the waste liquid tank, forming an inclined angle, the angle of which is not less than 5°.
[0064] This inclined design creates a gravity gradient, allowing the waste drawing fluid to flow back by gravity, reducing the power consumption for fluid return. It also effectively prevents copper powder impurities from depositing in the pipeline, thus preventing pipeline blockage. In this embodiment, the inclination angle α is not less than 5°, preferably 5° to 10°, which ensures smooth fluid return, further improves fluid return efficiency, and guarantees the continuity of waste drawing fluid recycling.
[0065] A supply pump 301a is connected to the supply pipe 301, and a return pump 302a is connected to the return pipe 302. The supply pump 301a is a gear pump, which can provide stable supply pressure, ensure uniform supply of liquid to each lubrication point, effectively avoid the decrease in lubrication and cooling effect caused by insufficient supply and unstable pressure, and improve production stability. The return pump 302a can help improve the return efficiency, avoid the problem of insufficient gravity flow and poor return when the waste drawing liquid volume is large or the pipeline is long. Combined with the gravity flow design, it can take into account both energy saving and efficiency, and further improve the system circulation stability.
[0066] In addition, the device is equipped with a temperature controller. The detection end of the temperature controller extends into the second discharge chamber A22 of the secondary liquid tank 100b, and the control end is electrically connected to the heating rod 201 and the refrigerator 204 respectively.
[0067] Furthermore, the temperature controller can monitor the temperature of the drawing fluid in real time and automatically adjust the temperature. When the temperature is higher than 45°C, the chiller 204 is activated to cool the fluid, and when the temperature is lower than 35°C, the heating rod 201 is activated to heat the fluid, ensuring that the temperature of the drawing fluid is always stable within the optimal process range, thereby improving the dimensional accuracy and surface quality of the product.
[0068] The detection end is located in the second discharge chamber A22 of the secondary liquid tank 100b, because this is the final stage before the drawing fluid enters the copper drawing machine 300. Temperature detection is more accurate, and it can also avoid the aging of the drawing fluid and wear of the equipment caused by excessively high or low temperatures, thus extending the service life of the equipment and the drawing fluid.
[0069] Furthermore, drain valves are provided at the bottom of the first sedimentation chamber A11 of the primary liquid tank 100a and the bottom of the second sedimentation chamber A12 of the secondary liquid tank 100b. The design of the drain valves facilitates the targeted cleaning of impurities in each sedimentation chamber by the staff. When copper powder accumulates to 15cm-20cm in the first sedimentation chamber A11, the corresponding inlet valve can be closed and the drain valve opened for separate cleaning. At this time, the system can continue to operate normally relying on the secondary liquid tank 100b without interrupting production. The sediment cleaning cycle of the secondary liquid tank 100b is about three times that of the primary liquid tank 100a. This modular cleaning design can significantly improve maintenance efficiency, reduce maintenance costs, and at the same time avoid excessive accumulation of impurities that may affect the sedimentation effect, ensuring long-term stable operation of the equipment.
[0070] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
