Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of nanomaterial preparation devices, specifically relating to a multi-station dual continuous wire feeding nanopowder electro-explosion device. Background Technology
[0002] In the field of nanomaterial preparation, nanopowders, due to their unique physicochemical properties, have shown great application potential in many fields such as electronics, medicine, and catalysis. Therefore, the efficient preparation of nanopowders has become a research hotspot. Currently, the electro-explosion method is one of the important methods for preparing nanopowders. Its principle is to subject materials such as metal wires to instantaneous high-energy discharge in a specific chamber, causing the materials to rapidly evaporate and condense under extreme conditions such as high temperature and high pressure, thereby forming nanoscale powder materials.
[0003] However, existing electro-explosion chamber equipment suffers from numerous problems in the wire feeding and material handling stages. For example, most equipment uses a single wire feeding mechanism, resulting in slow and discontinuous feeding speeds and low production efficiency. In powder production, frequent shutdowns for wire replacement not only waste time but also affect the quality stability of the powder. Simultaneously, traditional feeding mechanisms cannot precisely control the feeding amount, leading to unstable material supply during electro-explosion and making it difficult to guarantee the uniformity of nanoparticle size and consistent yield. These problems limit the large-scale industrial application of electro-explosion for preparing nanoparticles and fail to meet the growing market demand for nanoparticles. Utility Model Content
[0004] The purpose of this invention is to provide a multi-station, dual-continuous wire feeding electro-explosion device for nanoparticles, which solves the problems of low wire feeding and material feeding efficiency and low powder production efficiency in existing electro-explosion chamber equipment.
[0005] The technical solution adopted in this utility model is a multi-station, dual-continuous wire feeding nanopowder electro-explosion device, including an electro-explosion chamber. One end of the electro-explosion chamber is connected to the electro-explosion chamber cover via a hinge, and the other end is welded to the outlet flange of the electro-explosion chamber. A gas distribution plate is installed inside the electro-explosion chamber cover. Two sets of insulating turntables are symmetrically arranged in the center of the electro-explosion chamber. The insulating turntables are connected to the insulating shaft via expansion sleeves. Each set of insulating turntables has 8 to 12 sets of wire clamping mechanisms circumferentially. Each set of insulating turntables is correspondingly provided with a wire feeding mechanism. An electro-explosion mechanism is provided on the insulating turntables.
[0006] The feature of this utility model is that,
[0007] The cover of the electric explosion chamber is equipped with multiple air inlets and two observation windows; each set of insulating turntables is equipped with a set of electrode interface, shaft interface and electrical interface; the electrode interface, shaft interface and electrical interface are respectively located in the electric explosion chamber.
[0008] An insulated shaft is installed at the shaft interface. This insulated shaft is supported by a sealing ring and two bearings, and is securely connected to the electric explosion chamber via bearing supports. The sealing ring uses a high-pressure resistant magnetohydrodynamic seal to ensure sealing performance and operational stability.
[0009] The wire clamping mechanism includes a clamping mechanism body fixed at one end to an insulating turntable. The clamping mechanism body is hollow inside, with a U-shaped groove at the upper end and a long through hole at the lower part. A movable plunger is installed inside the clamping mechanism body, and the bottom end of the movable plunger is fixed to an insulating spring. The lower end of the insulating spring is connected to the bottom of the clamping mechanism body. A rubber wheel is fixedly connected to the movable plunger. The rubber wheel is located outside the clamping mechanism body and can move up and down along the long through hole. A curved baffle is also installed on the electric explosion cavity. The curved baffle is used to roll the rubber wheel to achieve continuous wire feeding.
[0010] The wire feeding mechanism includes a wire feeder, and the wire feeder and the wire spool are respectively connected to a fixed support. The wire feeder has a guide tube at the wire outlet end, and the end of the guide tube is located near the U-shaped groove of the wire clamping mechanism body.
[0011] The end face of the curved baffle that contacts the rubber wheel is a convex curved surface, gradually bulging from both ends to the middle.
[0012] The electric detonation mechanism includes a high-voltage electrode and a grounding electrode set between two adjacent wire feeding mechanisms; the distance between the high-voltage electrode and the grounding electrode is equal to the distance between two adjacent wire clamping mechanisms; an isolation tube is sleeved on the high-voltage electrode, and a grounding tube is sleeved on the grounding electrode, with the isolation tube sleeved inside the grounding tube and fixed to the electrode interface.
[0013] There is a gap between the cover of the electric explosion chamber and the gas distribution plate.
[0014] The beneficial effects of this invention are as follows: Compared with existing technologies for preparing nanoparticles using the electro-explosion method, this invention makes the following improvements in the explosion chamber and wire feeding mechanism:
[0015] First, the outer shell of the explosion chamber is designed to withstand working environmental pressures of 0.04 Pa to 1 MPa. Its structure includes multiple parts such as an air inlet, observation window, and electrode interface. The air inlet connects to a high-pressure gas tank to introduce protective gas, effectively preventing the metal wire from being oxidized during the electric explosion and ensuring the purity of the nanoparticles. The observation window allows operators to observe the electric explosion process in real time and adjust parameters promptly. The electrode interface allows for the stable installation of the high-voltage electrodes required for the electric explosion, ensuring a stable transmission of the strong pulse current to the metal wire. The insulated rotating shaft seal ensures the chamber's airtightness, preventing gas leakage and maintaining a stable electric explosion environment. The outlet flange connects to a separation device, facilitating the subsequent separation and collection of the generated nanoparticles.
[0016] Secondly, the wire feeding mechanism employs a unique design, using a servo motor to power the insulated rotating shaft, which in turn drives the wire spool to rotate via a tensioning sleeve. Two sets of electrodes are installed within the cavity for simultaneous electro-explosion, significantly improving production efficiency compared to traditional single-electrode electro-explosion methods. After electro-explosion, the wire spool drives the wire clamping mechanism to rotate. When the clamping mechanism passes the stop, the movable plunger is pressed down, creating a gap. The wire feeder then delivers the electro-explosion wire through a guide tube. Afterward, the clamping mechanism disengages from the curved stop and, under the action of an insulating spring, clamps the electro-explosion wire before feeding it into the electrode space. This precise wire feeding control ensures consistent wire length and position during each electro-explosion process, making the electro-explosion process more stable, effectively controlling the particle size distribution of nanoparticles, and obtaining uniform, high-quality nanoparticles.
[0017] Third, the wire clamping mechanism and the wire feeder work closely together. The wire clamping mechanism can firmly clamp metal wires of different materials and diameters, and has strong adaptability. The wire feeder can precisely control the wire feeding speed and amount according to a preset program. During the electro-explosion process, even if the metal wire experiences slight vibrations due to the electro-explosion, the wire feeding mechanism can quickly adjust to ensure that the metal wire is continuously and stably fed between the electrodes, reducing unstable factors during the electro-explosion process and further improving the preparation quality of nanoparticles.
[0018] Fourth, the explosion chamber has a compact overall structure and a rational layout of its components. The relative positions of the electrodes and the wire feeding mechanism have been optimized to ensure that the metal wire can fully absorb the energy of the strong pulse current at the moment of electro-explosion, thereby improving the efficiency of electro-explosion and reducing energy waste. At the same time, this compact design also reduces the overall size and production cost of the equipment, facilitating its installation, maintenance, and large-scale production applications.
[0019] Fifth, due to the instantaneous release of a large amount of energy during the electrical explosion, high temperatures and heat are generated, accompanied by plasma impact and metal sputtering, making the contact area between the wire clamping mechanism and the metal wire extremely susceptible to ablation, wear, and even structural degradation. To improve the durability of the wire clamping mechanism, this invention coats the area in contact with the metal wire with a high-temperature resistant and impact-resistant ceramic film, which significantly enhances its resistance to ablation and electrothermal stability. This ceramic coating not only effectively isolates high-temperature heat and reduces metal adhesion, but also lowers the coefficient of friction and improves the smoothness of wire feeding.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0032] Example 1
[0033] The multi-station dual-continuous wire feeding nanopowder electro-explosion device provided by this utility model, such as Figure 1-8As shown, the entire electric explosion chamber comprises an electric explosion chamber cover 1, an electric explosion chamber body 7, and an electric explosion chamber body outlet flange 12. The electric explosion chamber cover 1 and the electric explosion chamber body 7 are connected by hinges 6, and the electric explosion chamber body 7 and the electric explosion chamber outlet flange 12 are fixed by welding. The electric explosion chamber cover 1 is provided with six air inlets 2 and two observation windows 3, and a gas distribution plate 4 is installed on the inner side for uniformly distributing the airflow. The electric explosion chamber body 7 has two electrode interfaces 13, one rotating shaft interface 8, and one electrical interface 11. The insulating rotating shaft 10 is connected to the chamber body through a sealing ring 9 and a bearing support 32. The chamber body is provided with two sets of insulating turntables 18, which are connected to the insulating rotating shaft 10 through a tightening sleeve 31. The turntables are equipped with 12 sets of wire clamping mechanisms. The wire clamping mechanism consists of a clamping mechanism body 19, a movable plunger 20, a rubber wheel 21, and an insulating spring 22. When the rubber wheel 21 on the movable plunger 20 is pressed down by the curved baffle 24, and the metal wire 23 is fed in, when it rotates to the fixed position, the movable plunger 20 fits tightly with the clamping mechanism body 19 to ensure the clamping of the metal wire. Two fixed supports 29 are welded inside the cavity. The wire feeder 27 is fixed to the fixed supports 29 by bolts. The wire spool 28 is installed through the wire spool quick-release handle 30, which facilitates the replacement of the metal wire and improves the convenience of operation. The insulating shaft 10 is set on the shaft interface 8. The insulating shaft 10 is connected to the electric explosion cavity 7 through the sealing ring 9 and two bearings set on the bearing support 32.
[0034] The wire clamping mechanism includes a clamping mechanism body 19 fixed at one end to an insulating turntable 18. The clamping mechanism body 19 is hollow inside, with a U-shaped groove at the upper end and a long through hole at the lower end. A movable plunger 20 is installed inside the clamping mechanism body 19. The bottom end of the movable plunger 20 is fixed to an insulating spring 22, and the lower end of the insulating spring 22 is connected to the bottom of the clamping mechanism body 19. A rubber wheel 21 is fixedly connected to the movable plunger 20. The rubber wheel 21 is located outside the clamping mechanism body 19 and can move up and down along the long through hole. A curved baffle 24 is also provided on the electric explosion cavity 7. The curved baffle 24 is used to roll the rubber wheel 21 to achieve continuous wire feeding. The end face of the curved baffle 24 that contacts the rubber wheel 21 is a convex curved surface, which gradually bulges from both ends to the middle.
[0035] The wire feeding mechanism includes a wire feeder 27, and the wire feeder 27 and the wire spool 28 are respectively connected to the fixed support 29. The wire feeder 27 is provided with a guide tube 26 at the wire outlet end, and the end of the guide tube 26 is located near the U-shaped groove of the wire clamping mechanism body.
[0036] Example 2
[0037] The difference from Example 1 is that,
[0038] The electric detonation mechanism includes a high-voltage electrode 17 and a grounding electrode 16 disposed between two adjacent wire feeding mechanisms; the distance between the high-voltage electrode 17 and the grounding electrode 16 is equal to the distance between two adjacent wire clamping mechanisms; an isolation tube 15 is sleeved on the high-voltage electrode 17, and a grounding tube 14 is sleeved on the grounding electrode 16; the isolation tube 15 is sleeved in the grounding tube 14 and fixed to the electrode interface 13.
[0039] Electrical interface 11 is used to power the wire feeding mechanism inside the cavity, and is also a reserved interface for inserting sensors.
[0040] Before starting the equipment, a wire reel 28, wound with enough metal wire 23 required for the electric explosion experiment, is installed on the fixed support 29 inside the electric explosion chamber 7, ensuring that the metal wire 23 can be smoothly fed out from the wire feeder 27. Then, the power is turned on, and the servo motor is connected to the insulating shaft 10 via a coupling, driving the insulating turntable 18 to rotate through the expansion sleeve 31. When the insulating turntable 18 rotates to the fixed position, the movable plunger 20 is pressed down by the curved baffle 24. As the wire feeder 27 operates, the metal wire 23 is continuously fed into the gap between the movable plunger 20 and the clamping mechanism body 19. Simultaneously, the insulating turntable 18 continues to rotate until it reaches the fixed position. At this point, under the action of the insulating spring 22, the gap between the movable plunger 20 and the clamping mechanism body 19 gradually narrows, ultimately clamping the metal wire 23 completely. Thanks to the clamping action of the wire clamping mechanism, the subsequent wires will be pulled by the previous wire clamping mechanism, ensuring that the wire 23 remains stable during the wire feeding process and preventing the wire from slipping off the movable plunger 20.
[0041] Example 3
[0042] Specifically, such as Figure 3-4As shown, during operation, the insulating shaft 10 is driven to rotate by a servo motor. The insulating shaft 10 drives each wire clamping mechanism to rotate. Before the metal wire 23 is pulled out from the wire spool 28 and fed into the wire feeder 27 and then sent to the designated position via the guide tube 26, the wire clamping mechanism rotates with the insulating shaft 10 to a fixed position. The rubber wheel 21 contacts the curved baffle 24, causing the movable plunger 20 to be pressed down and no longer in contact with the clamping mechanism body 19. Then the metal wire 23 overlaps on the movable plunger 20. Afterward, the rotating mechanism drives the insulating shaft 10 to continue rotating, causing the rubber wheel 21 to disengage from the curved baffle 24 and the movable plunger 20 to contact with the clamping mechanism body 19. Thus, the metal wire 23 is pressed tightly in the wire clamping mechanism. As the insulating shaft 10 rotates, the wire feeding mechanism and the wire clamping mechanism repeat the above operation, so that the metal wire 23 can be fixed in sections on each wire clamping mechanism. In use, the metal wire 23 between two adjacent wire clamping mechanisms is continuously electro-exploded. Since it is clamped and fixed in segments, the subsequent metal wire 23 will not be detached from the wire clamping mechanism after electro-explosion, thus achieving stable and continuous wire feeding. As the mechanism is simple to operate and has high wire feeding efficiency, it can greatly increase the number of continuous electro-explosions and automatically and continuously produce ultrafine powder, realizing the mass production of ultrafine powder.
[0043] It should be noted that by setting different numbers of wire clamping mechanisms, the length of the metal wire 23 between adjacent wire clamping mechanisms can be adjusted accordingly, thereby adjusting the length of the metal wire 23 consumed each time it is electrically detonated. When the clamping mechanism passes through the curved baffle 24, the gap between the movable plunger 20 and the clamping mechanism body 19 changes from small to large and then back to small, thus achieving the effect of electrically detonating metal wires 23 of different diameters.
[0044] It should also be noted that the insulating shaft 10, the insulating turntable 18 and the wire clamping mechanism can all be made of insulating plastic, but are not limited to this. They can also be made of other solid insulating materials with the same effect, such as rubber and ceramics. No specific limitation is made here.
[0045] Example 4
[0046] like Figure 4As shown, the multi-station dual-continuous wire feeding nanopowder electro-explosion device provided by this invention includes an electro-explosion mechanism, a wire feeding mechanism, and a wire clamping mechanism. The electro-explosion mechanism consists of a high-voltage electrode 17 and a grounding electrode 16, with the distance between the high-voltage electrode 17 and the grounding electrode 16 equal to the distance between two adjacent wire clamping mechanisms. During the electro-explosion process, the electrode and the metal wire 23 do not directly contact each other. Current is discharged through the air gap between the electrode and the metal wire 23, thus achieving current conduction and significantly reducing electrode erosion. Simultaneously, because the electro-explosion process uses a large current, the metal wire undergoes melting, vaporization, and plasmaization, releasing a large amount of heat energy. Prolonged operation may lead to erosion at the contact point between the wire clamping mechanism and the metal wire. To prevent this problem, this invention coats the contact surface between the clamping mechanism and the metal wire 23—namely, the contact surface between the movable plunger 20 and the clamping mechanism body 19—with a high-temperature resistant ceramic coating 33, effectively improving the heat resistance of the clamping mechanism and preventing erosion.
[0047] It should be noted that coating the contact surface between the movable plunger 20 and the clamping mechanism body 19 with a ceramic layer is an effective method to prevent the clamping mechanism from being ablated during the electric explosion. Boron nitride (BN) or aluminum oxide (Al2O3) coatings are recommended, but not limited to these. Other solid insulating materials with the same effect can also be used, and no specific limitation is made here.
[0048] Example 5
[0049] This utility model's multi-station dual-continuous wire feeding nanopowder electro-explosion device internally includes two sets of wire feeding mechanisms, wire clamping mechanisms, and electro-explosion mechanisms. These components can operate synchronously, such as... Figure 2 As shown.
[0050] The specific operation steps of the multi-station dual continuous wire feeding method for electro-explosion of nanopowders are as follows:
[0051] Step 1: Install the wire spool with sufficient metal wire wound onto the fixed support inside the electric explosion chamber, and ensure that the metal wire can be smoothly fed out from the wire feeder;
[0052] Step 2: Turn on the power. The servo motor is connected to the insulating shaft through a coupling and drives the insulating turntable to rotate through the expansion sleeve. When the insulating turntable rotates to the fixed position of the curved baffle, the movable plunger is pressed down by the curved baffle. As the wire feeder runs, the metal wire is continuously fed into the gap between the movable plunger and the clamping mechanism body. At the same time, the insulating turntable continues to rotate, and the movable plunger completely clamps the metal wire under the action of the insulating spring.
[0053] Step 3: Electro-explode the metal wires between two adjacent wire clamping mechanisms using the grounding electrode and the high-voltage electrode.
[0054] The insulating rotating shaft 10 drives two sets of insulating turntables 18 to rotate synchronously via the expansion sleeve 31, thereby ensuring the coordination of the wire feeding and electro-explosion processes. To make the electro-explosion chamber 7 smaller and more compact, the wire feeding mechanism, wire clamping mechanism, and electro-explosion mechanism of the device all adopt a centrally symmetrical layout, distributed around the center point of the electro-explosion chamber 7. This design not only effectively reduces the overall size of the equipment and saves space, but also optimizes the coordination between various mechanisms, significantly improving the electro-explosion efficiency. Through this ingenious structural arrangement, the electro-explosion process becomes smoother, reducing unnecessary fluctuations and improving the stability and electro-explosion efficiency of the entire system, thereby greatly improving the production efficiency of nanopowders.
[0055] Example 6
[0056] The specific operating steps of the multi-station, dual-continuous wire feeding method for electro-explosion of nanopowders of this utility model are as follows:
[0057] The metal wires 23 with a diameter ranging from 0.2 to 1 mm, used to prepare the ultrafine powder, are cleaned and wound onto the wire reel 28. The electric explosion chamber cover 1 is then closed to seal it. The vacuum pump is turned on, and the gas pressure inside the electric explosion chamber 7 is reduced to below 200 Pa through the outlet flange 12. The outlet valve is then closed, and the inlet valve is opened, allowing argon gas to be introduced through the inlet 2 on the electric explosion chamber cover 1 to raise the gas pressure inside the electric explosion chamber 7 to 0.8 atmospheres. The inlet valve is then closed. The wire feeding unit is then started, continuously feeding the metal wires 23 from the wire reel 28 between the high-voltage electrode 17 and the grounding electrode 16. When the metal wire 23 is delivered between the two electrodes, a voltage of 9-15KV is applied to the high-voltage electrode 17. The high-voltage electrode 17 and the ground electrode 16 achieve an electric explosion by air gap breakdown between the two electrodes and the metal wire 23. Thus, the metal wire 23 undergoes solid heating, melting, liquefaction, vaporization, and explosive diffusion in a very short time, forming plasma and settling into ultrafine powder.
[0058] After the electro-explosion is completed, the outlet valve is opened and protective gas is simultaneously introduced into the electro-explosion chamber to ensure that the ultrafine powder formed by the electro-explosion can be smoothly discharged from the chamber before proceeding to the next step. For this purpose, a gas distribution plate is installed on the cover of the electro-explosion chamber to promote uniform airflow distribution. To verify the effect of the gas distribution plate in promoting uniform airflow distribution within the electro-explosion chamber, this embodiment uses Fluent software for simulation. Figure 9 The figure shows the airflow trajectory distribution within the reactor without a gas distribution plate, where Velocity Magnitude represents the velocity amplitude. It can be observed from the figure that the airflow exhibits a significant non-uniform distribution within the reactor, with localized eddies. This non-uniform flow field distribution leads to turbulent trajectories of the electrically explosive particles, reducing particle discharge efficiency. Figure 10The image shows the airflow trajectory distribution after the addition of the gas distribution plate, where Velocity Magnitude represents the velocity amplitude. A comparison clearly shows that the gas distribution plate significantly improves the flow field characteristics within the electric explosion cavity. The distribution plate redistributes the incoming airflow, creating a more uniform flow field distribution.
