Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tungsten wire drawing production technology, specifically relating to a dual ultrasonic alkaline cleaning device for tungsten wire surface treatment. Background Technology
[0002] In the process of producing electroplated brass wire by drawing tungsten wire, surface treatment is required before electroplating to remove graphite emulsion impurities, oil stains, and oxide scale remaining on the surface of the tungsten wire from previous processes. Currently, chemical degreasing is commonly used. Chemical degreasing utilizes the saponification and emulsification effects of alkaline solutions on the surface of the tungsten wire to remove oil, but its treatment effect is not ideal. Based on chemical degreasing, electrode plates are added to the solution for electrolytic degreasing. In addition to the above effects, it also has an electrochemical effect. During electrolytic degreasing, regardless of whether the part is used as the cathode or anode, a large amount of gas is released from the surface. This gas is easily adsorbed on the surface of the oil film, tearing the oil film into small oil droplets and carrying them to the liquid surface. At the same time, the gas stirs the solution, causing the solution near the surface of the part to be constantly renewed, accelerating the degreasing process. Compared with chemical degreasing, electrolytic degreasing is faster and more thorough. However, with process improvements, the efficiency and effect of electrolytic degreasing still cannot meet production requirements. Summary of the Invention
[0003] This invention addresses the shortcomings of existing electrolytic and chemical degreasing methods for tungsten wire surface treatment, which fail to effectively remove impurities and have low efficiency. It provides a dual-ultrasonic alkaline cleaning device for tungsten wire surface treatment. This device simultaneously electrolytically treats the tungsten wire in an alkaline solution while emitting ultrasonic waves into the solution. The high-frequency ultrasonic waves create vacuum cavities in the solution, drawing in gas to form bubbles. The shock waves generated by the bursting of these bubbles under pressure then impact and peel away the oil stains on the tungsten wire surface, achieving a clean surface and effectively improving the quality and efficiency of tungsten wire surface treatment.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A dual ultrasonic alkaline cleaning device for tungsten wire surface treatment includes two cleaning tanks connected end to end. Each cleaning tank has a storage tank below it, and a circulation pipeline is provided between each cleaning tank and the corresponding storage tank. The circulation pipeline allows the solution to circulate between the storage tank and the cleaning tank.
[0006] Each of the cleaning tanks is provided with two first partitions, and two overflow plates are provided between the two first partitions. Each overflow plate has multiple overflow grooves on its upper side. An ultrasonic device is provided between the two overflow plates, and at least two electrode plates are fixedly provided between the two overflow plates. The electrode plates in the two cleaning tanks are respectively connected to the positive and negative terminals of the power supply. The electrode plates are located above the ultrasonic device. The ultrasonic device is used to emit ultrasonic waves into the solution in the cleaning tank. The anode and cathode plates are used to electrolytically degrease the surface of the tungsten wire. The ultrasonic equipment is used to accelerate the surface treatment efficiency of the tungsten wire and ensure the surface treatment effect.
[0007] Preferably, each cleaning tank is provided with a second partition at both ends, and two first partitions are located between the two second partitions. Both the first and second partitions are provided with strip-shaped holes, through which tungsten wires pass to the solution area.
[0008] A rotating shaft is provided between adjacent first and second partitions. Multiple guide wheels are rotatably mounted on the rotating shaft. Each guide wheel corresponds to a multiple overflow groove. The tungsten wire is guided, lifted and transported through the guide wheels.
[0009] Multiple limiting plates are fixedly installed on opposite sides of the two overflow plates. Each limiting plate has a through groove on its upper side. The through groove corresponds to the overflow groove, and the overflow groove covers the corresponding through groove. The solution overflows from the through groove and then flows out through the overflow groove, effectively extending and ensuring that the solution submerges the tungsten wire.
[0010] Preferably, there is a gap between the ultrasonic device and the inner bottom surface of the cleaning tank, and a gap between the electrode plate and the ultrasonic device, to ensure the diffusion of current and ultrasonic waves in the solution and their contact with the solution.
[0011] Preferably, the circulation pipeline includes an inlet pipe, an outlet pipe, and an overflow pipe. The inner diameter of the inlet pipe is larger than that of the outlet pipe. One end of the inlet pipe is connected to the lower part of the storage tank, and the other end is connected between two overflow plates in the corresponding cleaning tank. One end of the outlet pipe is connected to the upper part of the storage tank, and the other end is connected between two overflow plates in the corresponding cleaning tank. One end of the overflow pipe is connected to the upper part of the storage tank, and the other end is connected between an adjacent first partition and an overflow plate in the corresponding cleaning tank. The solution enters the cleaning tank from the inlet pipe and flows back to the storage tank from the outlet pipe. Since the inflow is greater than the outflow, the solution overflows from the overflow tank and flows into the storage tank through the overflow pipe.
[0012] Preferably, the inlet pipe is equipped with a delivery pump and a filter. The filter is located on one side of the outlet end of the delivery pump. The delivery pump ensures the circulation of liquid flow, and the filter separates impurities in the solution.
[0013] Each outlet pipe is equipped with a valve to regulate the flow rate, thereby controlling the liquid level of the solution in the cleaning tank.
[0014] Preferably, the electrode plate adopts a mesh plate structure, with one of the two cleaning tanks having an anode plate and the other having a cathode plate. The electrode plates in each cleaning tank are arranged alternately to effectively increase the contact area between the electrode plate and the solution and ensure the electrolysis effect.
[0015] A dual-ultrasonic alkaline cleaning method for tungsten wire surface treatment, implemented using the aforementioned dual-ultrasonic alkaline cleaning device for tungsten wire surface treatment, includes the following steps:
[0016] Step 1: Tungsten wires pass through the cleaning tank via strip-shaped holes, with the spacing between two adjacent tungsten wires set to 8-12mm;
[0017] Step 2: Start the transfer pump, and the alkaline solution circulates between the cleaning tank and the storage tank through the circulation pipeline;
[0018] The alkaline solution level in the cleaning tank should be at least 0.5 cm higher than the tungsten wire;
[0019] Step 3: Apply electricity to the electrode plates and adjust the current density in the cleaning tank to 5-20 A / dm³. 2 ;
[0020] Simultaneously, power is supplied to the ultrasonic device, with the current controlled at 1.5-3A, to emit ultrasonic waves of 30-40KHZ into the alkaline solution;
[0021] The linear speed is controlled at 24.5-25.5 m / min.
[0022] Preferably, in step two, the alkaline solution is a sodium hydroxide solution with a concentration of 30-100 g / L and a pH value of 10-14. The cleaning tank between the two overflow plates is heated so that the temperature of the alkaline solution in the cleaning tank is 50-70°C.
[0023] The beneficial effects of this utility model through the above technical solution are as follows:
[0024] 1. This utility model sets up two sets of cleaning tanks to perform surface treatment on tungsten wires, effectively ensuring the surface treatment effect of tungsten wires. After the tungsten wires are treated in the previous cleaning tank, they directly enter the next cleaning tank to avoid oxidation. On this basis, they are treated again to prevent the surface of the treated tungsten wires from coming into contact with air again and oxidizing, and to prevent impurities such as oil and graphite emulsion from combining with the tungsten wires again, increasing the processing difficulty and affecting the efficiency of tungsten wire surface treatment.
[0025] 2. This utility model places electrode plates in an alkaline solution, and places electrode plates in two cleaning tanks as cathode and anode plates for the electrolysis reaction, respectively. The solution and tungsten wire form an electrolysis circuit, which effectively ensures the electrolysis effect and increases the contact area between the tungsten wire and the solution.
[0026] 3. This utility model uses a mesh plate structure to electrolyze the surface of the tungsten wire, further increasing the contact area between the plate and the solution and improving the electrolysis effect.
[0027] 4. This utility model uses an ultrasonic device installed in the cleaning tank. When ultrasonic waves propagate in the solution, they can form a cavity inside the solution. This cavity is in a vacuum state, and the gas in the solution will enter the vacuum cavity to form bubbles. When the bubbles are formed, they will burst under pressure and generate a powerful shock wave. The shock wave is used to impact and peel off the oil and impurities on the surface of the tungsten wire, effectively improving the cleaning effect of the tungsten wire surface.
[0028] 5. This utility model, by setting up two sequentially connected cleaning tanks, continuously treats the surface of the tungsten wire, effectively ensuring the treatment effect of the tungsten wire surface. After the first cleaning tank roughly treats the surface of the tungsten wire, most of the surface oil and dirt are removed, while the remaining parts are loosened. After the tungsten wire leaves the first cleaning tank, it directly enters the second cleaning tank. The electrolysis, ultrasonic waves, and alkaline solution in the second cleaning tank ensure a thorough cleaning of the tungsten wire surface, resulting in better surface treatment quality and avoiding the problem of uncoated nickel layers when plating the tungsten wire surface later, thus improving production efficiency.

Detailed Implementation
[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0040] like Figures 1-9 As shown, this embodiment provides a dual ultrasonic alkaline cleaning device for tungsten wire surface treatment, including two cleaning tanks 1 connected end to end. Each cleaning tank 1 has a storage tank 2 below it. The storage tank 2 contains an alkaline solution with a pH value of 10-14 and a concentration of 30-100 g / L. The temperature is maintained at 50-70℃. Specifically, the alkaline solution is a sodium hydroxide solution made by mixing sodium hydroxide and pure water. The alkaline solution can saponify and emulsify the oil on the surface of the tungsten wire, absorbing it. In this process, some graphite emulsion or oxide scale and other impurities on the surface of the tungsten wire are removed. A circulation pipeline is provided between each cleaning tank 1 and the corresponding storage tank 2. A delivery pump 15 and a filter 16 are provided on the circulation pipeline. In actual use, the delivery pump 15 circulates the solution between the storage tank 2 and the cleaning tank 1 through the circulation pipeline. On the one hand, it ensures effective contact between the solution and the tungsten wire. On the other hand, the filter 16 removes impurities in the solution, ensuring the reaction effect between the solution delivered to the cleaning tank 1 and the oil on the surface of the tungsten wire.
[0041] Each of the cleaning tanks 1 is provided with two first partitions 3, and two overflow plates 4 are provided between the two first partitions 3. The two overflow plates 4 and the side wall of the cleaning tank 1 together form an electrolytic reaction space. The adjacent first partitions 3 and overflow plates 4, together with the inner wall of the cleaning tank 1, form an overflow space. That is, the two overflow spaces are located at the two ends of the corresponding electrolytic reaction space. The two first partitions 3 of each cleaning tank 1 are sequentially divided into overflow space-electrolytic reaction space-overflow space. Each overflow plate 4 has multiple overflow channels 5 on its upper side. When the solution level in the electrolytic reaction space rises to a certain height, it flows from the overflow channels 5 at both ends to the overflow space.
[0042] The circulation pipeline includes an inlet pipe 12, an outlet pipe 13, and an overflow pipe 14. The inner diameter of the inlet pipe 12 is larger than that of the outlet pipe 13. One end of the inlet pipe 12 is connected to the lower part of the storage tank 2, and the other end is connected to the two overflow plates 4 in the corresponding cleaning tank 1. That is, the inlet pipe 12 connects the storage tank 2 and the electrolytic reaction space. A transfer pump 15 and a filter 16 are installed on the inlet pipe 12. The filter 16 is located on one side of the outlet end of the transfer pump 15. The filter 16 is a precision chemical liquid filter of model JF-2004. The solution in the storage tank 2 is transported to the filter 16 by the transfer pump 15. After the solid impurities are separated by the filter 16, the solution is transported to the cleaning tank 1 through the inlet pipe 12, that is, to the electrolytic reaction space. One end of the outlet pipe 13 is connected to the upper part of the storage tank 2, and the other end is connected to the corresponding cleaning tank 1. Between the two overflow plates 4 in the washing tank 1, i.e., the outlet pipe 13 connects the storage tank 2 and the electrolysis reaction space. The solution in the electrolysis reaction space flows back to the storage tank 2 through the outlet pipe 13. Since the diameter of the inlet pipe 12 is larger than the inner diameter of the outlet pipe 13, the solution level in the electrolysis reaction space gradually rises and comes into contact with the tungsten wire passing through the electrolysis reaction space, reacting with the oil on the surface of the tungsten wire. At the same time, during the circulation process, impurities on the surface of the tungsten wire are washed away. When the solution level rises to the height of the overflow tank 5, it flows out of the electrolysis reaction space from the overflow tank 5 and enters the overflow space. One end of the overflow pipe 14 connects to the upper part of the storage tank 2, and the other end connects to the adjacent first partition 3 and the overflow plate 4 in the corresponding washing tank 1. That is, the overflow pipe 14 connects the storage tank 2 and the overflow space. The solution in the overflow space flows into the storage tank 2 through the overflow pipe 14.
[0043] Each of the liquid outlet pipes 13 is equipped with a valve to regulate the flow rate of the liquid outlet pipe 13. By adjusting the valve opening, the liquid level in the electrolysis reaction space is adjusted to ensure that the tungsten wire is immersed in the solution.
[0044] Multiple limiting plates 10 are fixedly installed on opposite sides of the two overflow plates 4. Each limiting plate 10 has a through groove 11 on its upper side. The through groove 11 corresponds one-to-one with the overflow groove 5, and the overflow groove 5 covers the corresponding through groove 11. When the solution level in the electrolysis reaction space rises to the bottom of the through groove 11, it flows out through the through groove 11 to the overflow groove 5 and then enters the overflow space. The limiting plate 10 is fixedly connected to the corresponding overflow plate 4 by bolts. Thus, limiting plates of different through groove 11 sizes can be replaced as needed to adjust the flow rate of the solution flowing out of the electrolysis reaction space from the through groove 11. On the other hand, the through groove 11 ensures that the tungsten wire is aligned with the middle of the overflow groove 5 and guides the tungsten wire.
[0045] At least two electrode plates 7 are fixedly installed between the two overflow plates 4. The electrode plates in each cleaning tank 1 are arranged alternately, and the distance between two adjacent electrode plates in the same cleaning tank 1 is at least 2 cm. By setting multiple electrode plates 7, the difference between the current entering the cleaning tank 1 and the current on the electrode plate 7 is reduced, thereby further ensuring the uniform current distribution in the cleaning tank 1 and ensuring the electrolytic cleaning effect on the surface of the tungsten wire. The electrode plates 7 in the two cleaning tanks 1 are respectively connected to the positive and negative terminals of the power supply. The electrode plates serving as the positive and negative terminals are connected to the tungsten wire through the solution, and the electrode plates are electrically connected to the power supply, thus forming a current loop. The power supply supplies power to the electrode plates. Electrolytic treatment of the tungsten filament surface is achieved. Under electrolytic conditions, the polarization of the electrodes reduces the surface tension of the oil and solution, increasing the wettability of the solution on the tungsten filament surface. This reduces the adhesion between the oil film and the metal, making it easier for the oil to peel off and disperse into the solution for emulsification and removal. Simultaneously, a large amount of gas is released from the tungsten filament surface during electrolysis. This gas is adsorbed onto the oil film surface, tearing the oil film into small droplets that are carried to the liquid surface, thus separating the oil from the tungsten filament. The gas also stirs the solution, continuously renewing the solution near the tungsten filament surface and accelerating the degreasing process. In actual electrolysis, the electrolytic current density is maintained at 5-20 A / dm³. 2 .
[0046] An ultrasonic device 6 is installed between the two overflow plates 4. The ultrasonic device 6 uses an X6 ultrasonic generator manufactured by Zhangjiagang Huwei Electronics Co., Ltd. The ultrasonic device 6 is used to emit ultrasonic waves into the solution in the cleaning tank 1. Ultrasonic waves are high-frequency sound waves with a frequency greater than 20KHZ. When they propagate in the solution, they can form cavities inside the solution. These cavities are in a vacuum state, and the gas in the solution will enter the vacuum cavities to form bubbles. When the bubbles are formed, they burst under pressure, generating a powerful shock wave. Ultrasonic degreasing uses the "cavitation" effect to impact and peel off the oil stains on the metal surface to achieve the purpose of cleaning the surface. In actual use, the ultrasonic current is controlled at 1.5A-3A, and the ultrasonic frequency is controlled at 30KHZ-40KHZ.
[0047] The electrode plate 7 is located above the ultrasonic device 6, and there is a gap between the electrode plate 7 and the ultrasonic device 6. The electrode plate 7 adopts a mesh plate structure. The electrode plate 7 in one of the two cleaning tanks 1 is an anode plate, and the electrode plate 7 in the other cleaning tank 1 is a cathode plate. There is a gap between the ultrasonic device 6 and the inner bottom surface of the cleaning tank 1 to ensure the diffusion of the ultrasonic waves emitted by the ultrasonic device 6 in the solution, while ensuring sufficient and effective contact between the electrode plate and the solution.
[0048] An electric heating tube (not shown in the figure) is provided between the two overflow plates 4 in each of the cleaning tanks 1 to heat the alkaline solution in the cleaning tank 1 and keep its temperature at 50-70°C. The electric heating tube is arranged around the ultrasonic device 6, and there is a gap between the electrolytic heating tube and the ultrasonic device. The electrolytic heating tube is located below the electrode plate, and an anti-corrosion layer is provided on the outside of the electrolytic heating tube. The anti-corrosion layer is made of titanium.
[0049] Each cleaning tank 1 is provided with a second partition 8 at both ends, and two first partitions 3 are located between the two second partitions 8. Both the first partitions 3 and the second partitions 8 are provided with strip holes 9 for tungsten wires to pass through.
[0050] A rotating shaft is provided between adjacent first partition 3 and second partition 8. Multiple guide wheels are rotatably mounted on the rotating shaft. Each guide wheel corresponds to a multiple overflow groove 5. That is, after the tungsten wire passes through the guide wheel, it passes through the overflow space, the electrolysis reaction space, and then passes through the guide wheel again. This effectively ensures the height of the tungsten wire and the spacing between multiple tungsten wires, and avoids interference between adjacent tungsten wires.
[0051] A method for surface treatment of tungsten wire, implemented using a dual ultrasonic alkaline cleaning device for tungsten wire surface treatment as described above, includes the following steps:
[0052] Step 1: Tungsten wires pass through the cleaning tank via strip-shaped holes, with the spacing between two adjacent tungsten wires set to 8-12mm;
[0053] Preferably, the spacing between two adjacent tungsten wires in step one is 10 mm;
[0054] Step 2: Start the transfer pump, and the alkaline solution circulates between the cleaning tank and the storage tank through the circulation pipeline;
[0055] The alkaline solution level in the cleaning tank should be at least 0.5 cm higher than the tungsten wire;
[0056] In step two, the alkaline solution is a sodium hydroxide solution with a concentration of 30-100 g / L and a pH value of 10-14. The cleaning tank between the two overflow plates 4 is heated so that the temperature of the alkaline solution in the cleaning tank is 50-70℃.
[0057] Step 3: Apply electricity to the electrode plates and adjust the current density in the cleaning tank to 5-20 A / dm³. 2 ;
[0058] Simultaneously, power is supplied to the ultrasonic device, with the current controlled at 1.5-3A, to emit ultrasonic waves of 30-40KHZ into the alkaline solution;
[0059] The linear speed is controlled at 24.5-25.5 m / min;
[0060] Preferably, the linear velocity in step three is controlled at 25 m / min.
[0061] In use, the tungsten wire is set as follows: the tungsten wire passes through the strip hole 9 on the second partition 8 to reach the guide wheel. The guide wheel ensures the spacing between multiple parallel tungsten wires. Then, the tungsten wire passes through the strip hole 9 on the first partition 3 to enter the overflow space. It passes through the overflow groove 5 on the overflow plate 4 and the through groove 11 on the limiting plate 10 to enter the electrolysis reaction space. After passing through another overflow plate 4 to reach another overflow space, it passes through the guide wheel again to ensure the spacing between the tungsten wires. At this time, the tungsten wire passes through a cleaning tank 1, and then passes through another cleaning tank 1 again (the same process as above).
[0062] Tungsten Wire Surface Treatment: Pump 15 delivers the alkaline solution from storage tank 2 through filter 16 and inlet pipe 12 to the electrolysis reaction space. The solution then flows back into storage tank 2 from outlet pipe 13. Since the inner diameter of outlet pipe 13 is smaller than that of inlet pipe 12, the solution level in the electrolysis reaction space gradually rises. When the level reaches the position of the through-tank 11, the solution flows from through-tank 11 through overflow tank 5 to the overflow space. At this point, the solution submerges the tungsten wire. If the solution cannot completely submerge the tungsten wire, the liquid level can be further adjusted by adjusting the valve opening on outlet pipe 13 (i.e., the flow rate of inlet pipe 12 at this time). The flow rate of the liquid in the electrolysis reaction space is the flow rate of the liquid outlet pipe 13 and the flow rate of the solution between the bottom of the multiple through tanks 11 and the liquid surface. If the flow rate of the liquid outlet pipe 13 is reduced, the liquid level will rise again, and the flow rate of the solution discharged from the through tanks 11 will increase, thus maintaining the circulation and dynamic balance of the solution in the electrolysis reaction space. This ensures that the tungsten wire is immersed in the solution. Then, the electrode plate 7 and the ultrasonic device 6 are energized simultaneously to perform surface treatment on the conveyed tungsten wire. During this process, some of the grease that is separated out is absorbed by the solution, while the remaining solid impurities are separated by the filter 16 as the solution circulates, effectively ensuring the effect and efficiency of the tungsten wire surface treatment.
