Description

Technical Field

[0001] This application relates to the field of nanomaterials technology, and in particular to a nanomaterials collection device. Background Technology

[0002] Nanomaterials (typically referring to materials with sizes ranging from 1 to 100 nanometers) exhibit broad application potential in various fields due to their unique physical, chemical, and biological properties, such as medical and biotechnology, energy, electronic and optoelectronic devices, environmental and pollution control, materials science and industry, and everyday consumer goods. Among these, metallic nanomaterials are mainly concentrated in several high-value-added fields, with demand showing a highly specialized trend, and particle size range closely related to application scenarios. Electro-explosion is a technique that uses a high-energy pulsed current to instantaneously act on a metal wire, causing it to undergo a phase transition explosion and generate nanoparticles. This method is widely used in the preparation of metallic, alloy, and compound nanomaterials due to its non-equilibrium process, high energy density, and strong controllability.

[0003] Traditional electro-explosion manufacturing equipment uses filaments, where metal materials are drawn into thin filaments and then electro-exploded to generate nanoparticles. However, due to the different properties of various metals, some metals cannot be made into filaments, making them unsuitable for traditional electro-explosion equipment for nanomaterial preparation, thus limiting the production of such metal nanomaterials. Traditional electro-explosion equipment collects the generated metal nanomaterials by filling a collection tank with liquid. However, some metal nanomaterials are prone to chemical reactions, corrosion, or agglomeration when collected in liquid, resulting in unsatisfactory collected nanomaterials.

[0004] Therefore, it is necessary to improve the traditional electro-explosion manufacturing equipment to solve the above problems. Summary of the Invention

Detailed Implementation

[0033] Before describing the embodiments in detail, it should be understood that this application is not limited to the detailed structures or element arrangements described below or in the accompanying drawings. This application can be implemented in other ways. Furthermore, it should be understood that the wording and terminology used herein are for descriptive purposes only and should not be construed as limiting. The terms "comprising," "including," "having," and similar expressions used herein mean to include the items listed thereafter, their equivalents, and other additional items. In particular, when describing "an element," this application does not limit the number of elements to one, but may include multiple elements.

[0034] Please also refer to Figures 1 to 3 As shown, this application provides a nanomaterial collection device 10, which can be used to manufacture and collect nanomaterials (such as metal nanopowders, metal oxides, or other compound nanopowders) by electro-explosion, without the need for liquid collection. Specifically, the nanomaterial collection device 10 includes a collection tank 12 and a clamping mechanism 14. The collection tank 12 is made of metal, for example. A collection cavity 16 is formed inside the collection tank 12, and a first electrode assembly 18 and a second electrode assembly 20 are provided inside the collection cavity 16 and electrically connected to an external power source. The first electrode assembly 18 and the second electrode assembly 20 are electrically connected via a metal target 22 to generate nanomaterials through electro-explosion. The clamping mechanism 14 is used to clamp and fix the metal target 22, which is electrically connected to the first electrode assembly 18 and the second electrode assembly 20, thereby realizing circuit conduction. This application provides a clamping mechanism 14 inside the collection tank 12 for clamping and fixing the metal target 22, so that the metal target 22 can be directly placed inside the collection tank 12 for reaction, realizing the dry collection of metal nanomaterials without the use of liquid. This effectively solves the problem that metal cannot be made into wire for electro-explosion, and the clamping mechanism 14 can be adapted to metal targets 22 of various shapes, thus broadening the application range.

[0035] In this embodiment, the clamping mechanism 14 is detachably connected to the first electrode assembly 18, and the clamping mechanism 14 is made of a conductive material, such as metal, so that the metal target 22 can be electrically connected to the first electrode assembly 18 through the clamping mechanism 14. The metal target 22 is electrically connected to the first electrode assembly 18 through the clamping mechanism 14, and the other end of the metal target 22 is in electrical contact with the second electrode assembly 20, thereby achieving circuit conduction. In this case, the clamping mechanism 14 simultaneously serves to clamp and fix the metal target 22 and provide electrical conduction.

[0036] It should be noted that in some other embodiments, not shown in the figures, the conductivity of the clamping mechanism may not be limited. The clamping mechanism can be made of conductive material or non-conductive material. Specifically, the clamping mechanism can be fixedly disposed in the collection cavity. For example, the clamping mechanism can be fixedly connected to the inner wall of the collection tank through a fixing structure, and the clamping mechanism does not form a conductive path with the collection tank. The first electrode assembly includes a first electrode rod and a first electrode plate connected to the first electrode rod. The second electrode assembly includes a second electrode rod and a second electrode plate connected to the second electrode rod. After the clamping mechanism clamps and fixes the metal target, one end of the metal target abuts against the first electrode plate and is electrically connected, and the other end abuts against the second electrode plate and is electrically connected, thereby realizing circuit conduction. In this case, the clamping mechanism only plays the role of clamping and fixing the metal target and does not play the role of electrical conduction. Alternatively, in some other embodiments (not shown in the figures), the clamping mechanism can be mounted on the first electrode assembly or the second electrode assembly. In this case, the clamping mechanism can be made of insulating material. The first electrode assembly or the second electrode assembly only serves to support and fix the clamping mechanism and the metal target. After the clamping mechanism clamps and fixes the metal target, one end of the metal target is electrically connected to the first electrode assembly and the other end is electrically connected to the second electrode assembly. For example, the design of the first electrode plate and the second electrode plate described above can be used.

[0037] In this embodiment, the first electrode assembly 18 serves as either the anode or the cathode, and the second electrode assembly 20 serves as the other anode or cathode. The first electrode assembly 18 and the second electrode assembly 20 can be connected to the positive and negative terminals of a power supply, respectively. After the power is turned on, a high-pulse voltage is applied to the metal target 22, causing an electro-explosion on the metal target 22 and forming nanoparticles. In this embodiment, the first electrode assembly 18 is the cathode, and the second electrode assembly 20 is the anode.

[0038] The clamping mechanism 14 expands the range of electrically explosive metal materials that can be used. Optionally, the metal target 22 can take various shapes, such as rod, strip, or block. The clamping mechanism 14 of this application can securely clamp and fix the metal target 22 of various shapes. In this embodiment, the metal target 22 is a cylindrical rod. The clamping mechanism 14 can clamp one end of the metal target 22, and the other end of the metal target 22 abuts against the second electrode assembly 20.

[0039] In the illustrated embodiment, as Figure 1 As shown, the collection tank 12 is designed in a cylindrical shape, but this application does not limit the shape of the collection tank 12. In other embodiments, the collection tank 12 can also be designed in other shapes. The collection tank 12 has an axial direction x, and the collection tank 12 can be placed in the up-down direction when in use. In this case, the axial direction x is the up-down direction.

[0040] like Figure 2 and Figure 3As shown, the collection tank 12 includes a lid 26 and a tank body 24 connected vertically along the axial direction x. The tank body 24 has a top-opening structure. The lid 26 is detachably fitted onto the top opening of the tank body 24 and encloses the tank body 24 to form a collection cavity 16. For example, the lid 26 is threaded or snap-fitted to the top opening of the tank body 24, thereby achieving detachable fixation between the lid 26 and the tank body 24. Preferably, the diameter of the lid 26 is larger than the diameter of the tank body 24. The lid 26 has a bottom-opening structure. The radially inner sidewall of the lid 26 has an internal thread, and the radially outer sidewall of the top of the tank body 24 has an external thread. The internal and external threads are threadedly connected, allowing the lid 26 to be fitted onto the tank body 24 by a threaded connection. The snap-fit ​​connection can be similar to the rotating snap-fit ​​connection between the lid and the body of a pressure cooker, which will not be described in detail here.

[0041] In this embodiment, as Figure 3 As shown, the first electrode assembly 18 includes a first electrode rod 28, and the second electrode assembly 20 includes a second electrode rod 30 and an electrode plate 32. The first electrode rod 28 and the second electrode rod 30 are spaced apart. A clamping mechanism 14 is connected to the bottom end of the first electrode rod 28, and the electrode plate 32 is connected to the bottom end of the second electrode rod 30, for example, by bolts. The length of the first electrode rod 28 is less than the length of the second electrode rod 30, and both the first electrode rod 28 and the second electrode rod 30 are, for example, arranged along the axial direction x. Therefore, the electrode plate 32 is located below the clamping mechanism 14, and the position of the electrode plate 32 corresponds to the position of the clamping mechanism 14 in the axial direction x, so that the metal target 22 abuts against the electrode plate 32.

[0042] Please also refer to Figures 4 to 6As shown, the top ends of the first electrode rod 28 and the second electrode rod 30 are both connected to the cover 26. Specifically, a limiting member 34 is fixedly provided on one side of the cover 26 located in the collection chamber 16. The limiting member 34 is, for example, block-shaped. The first electrode rod 28 and the second electrode rod 30 pass through the limiting member 34 and the cover 26, respectively, and are fixedly connected to the limiting member 34. In the illustrated embodiment, the middle region of the cover 26 is provided with a first through hole 36 and a second through hole 38 penetrating the cover 26. The limiting member 34 is provided with a first fixing hole 40 and a second fixing hole 42. The top end of the first electrode rod 28 passes through the first fixing hole 40 and the first through hole 36 from bottom to top and extends out of the cover 26. The top end of the second electrode rod 30 passes through the second fixing hole 42 and the second through hole 38 from bottom to top and extends out of the cover 26. The first electrode rod 28 is fixedly connected to the first fixing hole 40, for example, by a threaded connection. The second electrode rod 30 is fixedly connected to the second fixing hole 42, for example, by a threaded connection. The limiting member 34 is fixedly connected to the cover 26, for example, by a screw, thereby limiting and fixing the first electrode assembly 18 and the second electrode assembly 20, preventing the first electrode assembly 18 and the second electrode assembly 20 from loosening due to excessive impact force during the electro-explosion process.

[0043] To enhance the airtightness of the collection tank 12, a first sealing ring 44 is provided at the connection between the cover 26 and the tank body 24, and a second sealing ring 46 is provided at the connection between the first electrode rod 28 and the first through hole 36 and the connection between the second electrode rod 30 and the second through hole 38, respectively. Preferably, a first receiving groove 48 is provided at the edge of the cover 26 on one side of the collection chamber 16, and the first sealing ring 44 is received in the first receiving groove 48; furthermore, the width of the first receiving groove 48 or the first sealing ring 44 is approximately the same as the thickness of the side wall of the tank body 24, and when the cover 26 is connected to the tank body 24, the top of the cover 26 abuts against the first sealing ring 44 to enhance airtightness. Two second sealing rings 46 are provided on one side of the cover 26 located in the collection chamber 16. Specifically, two second receiving grooves 50 are provided on the top surface of the limiting member 34. The two second receiving grooves 50 are respectively arranged around the first fixing hole 40 and the second fixing hole 42. That is, the first fixing hole 40 and the second fixing hole 42 are respectively connected to the corresponding second receiving grooves 50. The two second sealing rings 46 are respectively arranged around the first electrode rod 28 and the second electrode rod 30, and are respectively housed in the corresponding second receiving grooves 50. For example, the second sealing rings 46 are pressed between the second receiving grooves 50 and the cover 26, thereby achieving the sealing of the first through hole 36 and the second through hole 38 and enhancing the airtightness of the collection tank 12.

[0044] In the illustrated embodiment, as Figure 4 and Figure 5As shown, the first electrode assembly 18 includes a first conductive sleeve 52, and the second electrode assembly 20 includes a second conductive sleeve 54. The first conductive sleeve 52 is fitted over the portion of the first electrode rod 28 that extends beyond the cover 26, and the second conductive sleeve 54 is fitted over the portion of the second electrode rod 30 that extends beyond the cover 26. The first conductive sleeve 52 and the second conductive sleeve 54 are, for example, single-core aviation connectors for connecting electrical equipment, used to connect power supplies and equipment, ensuring stable current transmission, high reliability, and strong anti-interference capability, and can be connected to the anode and cathode via wires.

[0045] In the illustrated embodiments, please also refer to Figure 1 and Figure 2 As shown, the cover 26 is equipped with an inlet structure and an outlet structure communicating with the collection chamber 16. The inlet structure is used to connect to an external gas source to fill the collection chamber 16 with gas, and the outlet structure is used to discharge gas. For example, the instantaneous high voltage generated during an electric explosion will drive some gas and powder to be discharged through the outlet structure, preventing excessive pressure inside the collection tank 12. Different types of atmospheres can be introduced into the collection chamber 16 according to actual needs, such as argon + oxygen / nitrogen / methane, etc. For example, argon + oxygen can generate oxides. For example, during use, a protective gas can be introduced into the collection chamber 16 through the inlet structure, so that the original gas in the collection chamber 16 is discharged through the outlet structure, thus making the collection chamber 16 contain only protective gas such as argon; when it is necessary to prepare metal oxides or other compound powders, oxygen or other reactive gases and argon can be introduced into the collection chamber 16.

[0046] Furthermore, such as Figure 4 and Figure 5 As shown, the air intake structure includes an air intake nozzle 56 and a first air hole 58, and the air outlet structure includes an air outlet nozzle 60 and a second air hole 62. The first air hole 58 and the second air hole 62 are disposed through the cover 26. The air intake nozzle 56 is located outside the cover 26 and installed in the first air hole 58, and the air outlet nozzle 60 is located outside the cover 26 and installed in the second air hole 62.

[0047] In the illustrated embodiments, please also refer to Figure 8 and Figure 9 As shown, the clamping mechanism 14 includes a fixed base 64 and a movable member. The fixed base 64 is fixedly mounted on the first electrode assembly 18 and has a first clamping surface 66. The movable member is movably connected to the fixed base 64 and has a second clamping surface 68. A clamping space 70 for clamping the metal target 22 is formed between the first clamping surface 66 and the second clamping surface 68. The electrode plate 32 is located below the clamping space 70 to facilitate contact with the bottom end of the metal target 22 to form electrical contact.

[0048] The movable component can move between a first position and a second position relative to the fixed base 64. When the movable component is in the first position, the second clamping surface 68 is close to the first clamping surface 66 and can cooperate with the first clamping surface 66 to clamp the metal target 22. When the movable component is in the second position, the second clamping surface 68 is away from the first clamping surface 66 to open the clamping space 70. At this time, the metal target 22 can be placed into the clamping space 70 or removed from the clamping space 70.

[0049] Specifically, please also refer to Figure 8 As shown, the fixing base 64 includes a connecting portion 72 and a first clamping portion 74 and a mounting portion 76 connected to one side of the connecting portion 72 and spaced apart. The fixing base 64 is U-shaped, with the U-shaped opening facing the second electrode rod 30. A movable space 78 is formed between the first clamping portion 74 and the mounting portion 76, and a first clamping surface 66 is formed on the side of the first clamping portion 74 located in the movable space 78. The movable component includes a lead screw 80 and a second clamping portion 82. The mounting portion 76 has a screw hole 84 communicating with the movable space 78. The lead screw 80 is threaded into the screw hole 84, and both ends of the lead screw 80 extend out of the screw hole 84. The second clamping portion 82 is located in the movable space 78 and connected to the end of the lead screw 80 that extends into the movable space 78. The second clamping surface 68 is formed on the side of the second clamping portion 82 opposite to the first clamping surface 66.

[0050] Preferably, such as Figure 9 As shown, the second clamping part 82 has a connecting hole 86 on the side opposite to the second clamping surface 68. The second clamping part 82 is rotatably connected to the lead screw 80 through the connecting hole 86, so that the second clamping part 82 does not rotate when the lead screw 80 rotates, that is, the second clamping part 82 does not rotate with the lead screw 80, so that the second clamping surface 68 can always maintain the best clamping direction, and the second clamping part 82 can better perform the clamping action and increase the clamping stability. The other end of the lead screw 80 extending out of the mounting part 76 is fixedly connected to a rotating head 88, so that the user can rotate the lead screw 80 by rotating the rotating head 88, which brings convenience to the user.

[0051] Furthermore, a first clamping groove 90 is recessed at the center of the first clamping surface 66, and a second clamping groove 92 is recessed at the center of the second clamping surface 68. Both the first clamping groove 90 and the second clamping groove 92 extend along the axial direction x, and the second clamping groove 92 corresponds to the position of the first clamping groove 90. The first clamping groove 90 and the second clamping groove 92 can be designed to fit the shape of the metal target 22 to increase the contact area between the clamping surface and the metal target 22, making the force on the metal target 22 more uniform and the clamping more stable.

[0052] By rotating the lead screw 80, the second clamping part 82 can be controlled to move laterally within the active space 78, thereby enabling the second clamping part 82 to move closer to the first clamping part 74 and cooperate with the first clamping part 74 to clamp the metal target 22, or the second clamping part 82 to move away from the first clamping part 74 to open the clamping space 70.

[0053] More specifically, please also refer to Figure 7 As shown, the clamping mechanism 14 also includes a conductive connector 94. The fixing seat 64 is detachably fixed to the connector 94, for example, by screws. The bottom end of the first electrode rod 28 is provided with a mounting seat 96, which is square, for example, to facilitate installation. The connector 94 is provided with at least one first fixing structure 98, and the mounting seat 96 is provided with at least one second fixing structure 100. The first fixing structure 98 and the second fixing structure 100 are detachably fixed, for example, by bolts, thereby connecting and fixing the connector 94 to the mounting seat 96, and thus fixing the clamping mechanism 14 relative to the first electrode rod 28 via the connector 94. Preferably, multiple first fixing structures 98 and second fixing structures 100 are provided. For example, both the first fixing structure 98 and the second fixing structure 100 are hole structures. Multiple hole structures are arranged at intervals along the axial direction x. Different first fixing structures 98 are connected to different second fixing structures 100 to realize the adjustment of the vertical position of the connector 94, that is, the adjustment of the vertical position of the clamping mechanism 14, and thus the adjustment of the vertical position of the metal target 22. This allows the position of the clamping mechanism 14 to be appropriately adjusted according to the length of the metal target 22, so that the bottom end of the metal target 22 can better abut against the electrode plate 32 to achieve electrical contact.

[0054] In this embodiment, as Figure 7 As shown, the connector 94 is T-shaped and includes a first part 102 and a second part 104 that are connected. The first part 102 is arranged horizontally and the second part 104 is arranged vertically. The connecting part 72 is detachably and fixedly connected to the first part 102. The first fixing structure 98 is arranged on the second part 104 to avoid interference with the fixing seat 64 during the installation of the fixing structure, and at the same time facilitates the installation and connection of the first fixing structure 98 and the second fixing structure 100.

[0055] It should be understood that, in other embodiments, the vertical position adjustment of the connector 94 can also be achieved in other ways. For example, the connector 94 is provided with a first sliding structure, and the mounting base 96 is provided with a second sliding structure. The first sliding structure and the second sliding structure are slidably connected, thereby realizing the vertical position adjustment of the connector 94, the clamping mechanism 14 and the metal target 22.

[0056] In summary, this application provides a nanomaterial collection device, including a collection tank and a clamping mechanism. A collection cavity is formed within the collection tank, and a first electrode assembly and a second electrode assembly, electrically connected to an external power source, are disposed within the collection cavity. The first and second electrode assemblies are electrically connected via a metal target to generate nanomaterials through an electro-explosion. The clamping mechanism is used to clamp and fix the metal target. This application, by providing a clamping mechanism within the collection tank to hold and fix the metal target, allows the metal target to be directly placed within the collection tank for reaction, achieving dry collection of metal nanomaterials without the need for liquids. This effectively solves the problem that metals cannot be made into wires for electro-explosion, and the clamping mechanism can adapt to metal targets of various shapes, broadening its application range.

[0057] The concepts described herein may be implemented in other forms without departing from their spirit and characteristics. The specific embodiments disclosed should be considered illustrative rather than restrictive. Therefore, the scope of this application is determined by the appended claims, and not by the preceding description.
