Description

Technical Field

[0001] This invention relates to the field of alloy powder preparation technology, specifically to an apparatus for preparing non-ferrous metal alloy powder. Background Technology

[0002] Many high-end manufacturing sectors now require non-ferrous metal alloy powders, and the quality requirements for these powders are becoming increasingly stringent. Several powder preparation methods are currently used, each with its own drawbacks; some powders are prone to oxidation, while others have irregular shapes, failing to meet the demands of high-end applications.

[0003] Centrifugal atomization powder production has a relatively good effect. It does not rely on high-pressure gas or high-pressure water. It only needs to open liquid outlet holes or pipes on the bottom and outer periphery of the cylinder. It relies on the centrifugal force of high-speed rotation to break the molten non-ferrous metal liquid into powder. However, because the centrifugal atomization device breaks the liquid filament by rotating, its crushing energy is limited. Therefore, it is mainly used to produce medium-coarse particle size, high sphericity, low oxygen fine powder. It is not suitable for making ultrafine powder and lacks a mechanism to cooperate with physical crushing. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a device for preparing non-ferrous metal alloy powders, which solves the problem that current centrifugal atomization equipment is unable to produce ultrafine powders.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a preparation device for non-ferrous metal alloy powder, comprising a tripod support on which a powder-making cylinder is mounted, and further comprising: a centrifugal atomizing component, the centrifugal atomizing component comprising a drive motor, a centrifugal cylinder connected to the drive motor, and a gas filling pump, the gas filling pump being responsible for delivering inert gas to the interior of the powder-making cylinder, the centrifugal cylinder having a plurality of annularly distributed liquid outlet holes near its bottom outer end, the outer side of the plurality of liquid outlet holes forming a liquid-splashing zone; and a droplet breaking component, the droplet breaking component comprising a first breaking ring and a second breaking ring disposed around the outer periphery of the liquid outlet holes. The first and second crushing rings each have multiple densely distributed helical teeth on their inner sides, which are responsible for colliding and crushing the ejected droplets; a driving component, which includes a driving source, is responsible for driving the first or second crushing ring to rotate in the opposite direction to the centrifuge cylinder; an alternating operation component, which includes a micro push rod, is responsible for driving the first and second crushing rings to reciprocate up and down. When the first and second crushing rings move to the liquid ejection zone, they enter a rotating state; when they move away from the liquid ejection zone, they switch to a stationary state, so that the centrifuged powder on the first or second crushing rings automatically falls off.

[0006] Preferably, a first driven toothed ring is fixedly connected to the outer wall of the first crushing ring, a second driven toothed ring is fixedly connected to the outer wall of the second crushing ring, a first drive plate is rotatably connected to the top of the first crushing ring, and a second drive plate is rotatably connected to the bottom of the second crushing ring.

[0007] Preferably, the driving component includes a geared motor, the output end of which is fixedly connected to a drive shaft, and the drive shaft is fitted with a first driving wheel that meshes with a first driven gear ring and a second driving wheel that meshes with a second driven gear ring.

[0008] Preferably, a drive disc is fixedly connected to the drive shaft, and multiple linkage rods are fixedly connected to the drive disc. Multiple drive holes corresponding to the linkage rods are opened on one side of both the first drive wheel and the second drive wheel.

[0009] Preferably, the linkage rod includes a fixed cylinder, and a top rod is slidably connected inside the fixed cylinder. A reset member is fixedly connected to the bottom of the top rod and the inner bottom of the fixed cylinder.

[0010] Preferably, the centrifuge cylinder is provided with a liquid pushing component, which includes a hydraulic rod. A sealing plate is fixedly connected to the bottom of the hydraulic rod. A squeezing plate is slidably connected inside the centrifuge cylinder. When the sealing plate descends, it touches the squeezing plate to squeeze the liquid.

[0011] Preferably, the squeezing plate has a vent hole, the bottom of the sealing plate is provided with a sealing gasket, and an annular plate is fixedly connected to the inner wall of the vent hole. When the sealing gasket descends, it abuts against the annular plate.

[0012] Preferably, a pull ring plate is fixedly connected to the squeezing plate, the pull ring plate has multiple air holes, and a push ring plate is slidably connected to the outer wall of the hydraulic rod.

[0013] Preferably, the push ring plate is slidably connected to the inside of the pull ring plate and is restricted to its internal movement, and a pressure relief valve is provided on the sealing plate.

[0014] Preferably, a flow control valve is provided inside the liquid outlet, and the flow control valve is electrically connected to a controller.

[0015] This invention provides an apparatus for preparing non-ferrous metal alloy powder. It has the following beneficial effects: 1. The present invention sets a first crushing ring on the inner wall of the powder making cylinder. When the droplets are pulled into tiny droplets, they will collide with the oblique teeth, automatically crushing and falling off. Since the droplets are thrown out at a high speed, the extended oblique teeth are exactly on the trajectory of the droplet tangent. The collision causes the droplets to be further crushed, thereby improving the fineness of the powder making in the centrifugal atomization equipment.

[0016] 2. This invention, by setting up a first crushing ring and a second crushing ring that can work alternately, and through the ingenious cooperation of the driving component and the alternating moving component, transmits power alternately. This allows the first crushing ring to automatically stop and move away from the liquid outlet when it loses power, while the second crushing ring moves closer to the liquid outlet and takes over from the first crushing ring to continue crushing the droplets. This eliminates the need to stop the machine, speeds up the powder production process, and improves work efficiency.

[0017] 3. This invention sets up a first crushing ring and a second crushing ring, one moving and one stationary. For example, when the first crushing ring is stationary, the second crushing ring rotates. When the first crushing ring is stationary, the powder adhering to the inner side of the inclined teeth automatically falls off, achieving the purpose of automatically cleaning the inner edge of the inclined teeth. When the working states are switched, the inclined teeth of the first and second crushing rings can be in a relative motion state, so that the powder falling on the top surface of the inclined teeth of the first crushing ring is automatically cleaned without manual cleaning, saving time and effort.

[0018] 4. By setting up hydraulic rods and squeezing plates, the sealing plate moves down and contacts the annular plate, creating a large pressure force that squeezes the liquid downwards. This solves the problem of the liquid sliding down too slowly under high-speed centrifugation, which not only improves the powdering efficiency but also ensures that the output volume is the same, thereby ensuring that the powder size is consistent and improving the powdering quality.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to the appendix. Figure 1 -Appendix Figure 4 This invention provides an apparatus for preparing non-ferrous metal alloy powder, including a tripod 1 with a powder-making cylinder 2 mounted on it, and further including: a centrifugal atomizing component 3, which includes a drive motor 31, a centrifugal cylinder 32 connected to the drive motor 31, and a gas filling pump. The gas filling pump is responsible for delivering inert gas to the interior of the powder-making cylinder 2. The centrifugal cylinder 32 has multiple annularly distributed liquid outlet holes 33 near its bottom outer end, forming a liquid-splashing zone outside the multiple liquid outlet holes 33; and a droplet breaking component 4, which includes a first breaking ring 41 and a second breaking ring 42 disposed around the liquid outlet holes 33. The inner side of each of the two breaking rings 42 is provided with multiple densely distributed oblique teeth, which are responsible for colliding and breaking the ejected droplets; the driving component 5 includes a driving source, which is responsible for driving the first breaking ring 41 or the second breaking ring 42 to rotate in the opposite direction to the centrifuge cylinder 32; the alternating operation component 6 includes a micro push rod 61, which is responsible for driving the first breaking ring 41 and the second breaking ring 42 to move up and down reciprocally. When the first breaking ring 41 and the second breaking ring 42 move to the liquid ejection zone, they enter the rotating state. When they move away from the liquid ejection zone, they switch to the stationary state, so that the centrifuged powder on the first breaking ring 41 or the second breaking ring 42 automatically falls off.

[0023] Please see the appendix Figure 1A sealing cover 8 is provided on the powder making cylinder 2, which is detachably connected to the powder making cylinder 2 by multiple bolts. The output end of the drive motor 31 is fixedly connected to the inner bottom surface of the centrifuge cylinder 32. The gas filling pump fills the powder making cylinder 2 with inert gas through the pipeline. The figure shows the pipe opening, which means that the pipeline is installed from here and kept in a sealed state. Then the content of inert gas inside is controlled to isolate the non-ferrous metal from oxygen and avoid oxidation.

[0024] During centrifugal atomization, the molten alloy powder liquid is first poured into the centrifuge cylinder 32, the sealing cap 8 is closed, and the drive motor 31 is turned on. The drive motor 31 drives the centrifuge cylinder 32 to rotate at high speed. Under the action of high-speed centrifugation, the liquid is thrown out tangentially from the liquid outlet 33. The high-speed centrifugal force pulls the liquid film into liquid filaments, and the liquid filaments are pulled into tiny liquid droplets until they become mist-like droplets, which then quickly lose temperature and fall off as powder.

[0025] The outlet hole 33 is equipped with a flow control valve, which is electrically connected to a controller.

[0026] Specifically, the flow control valve receives the control signal from the controller to achieve automatic flow regulation. Initially, the flow control valve can be closed until the rotation speed reaches the set speed, and then the flow control valve can be opened to make the liquid reach the set centrifugal speed and be thrown out, thus ensuring the centrifugal quality of the droplets.

[0027] Furthermore, to improve the degree of droplet breakage, a ring of oblique teeth is set on the inner wall of the powder-making cylinder 2. When the droplets are pulled into tiny droplets, they will collide with the oblique teeth, automatically crush them and fall off. Since the droplets that have just been thrown out are moving very fast, the extended oblique teeth are exactly on the trajectory of the droplet tangent. The collision causes the droplets to be further crushed, thereby improving the fineness of the powder making in the centrifugal atomization equipment.

[0028] Specifically, the two layers of oblique teeth are at the same height and are ideally in contact with each other, while the first crushing ring 41 and the second crushing ring 42 are in a sliding seal relationship, making it difficult for powder to enter the outside of the first crushing ring 41 and the second crushing ring 42. When there is metal powder falling on the lower oblique teeth, the upper oblique teeth can push and clean this part of the powder when they rotate, thereby achieving the purpose of automatic cleaning of powder at multiple locations.

[0029] Please see the appendix Figure 4 The outer wall of the first crushing ring 41 is fixedly connected to a first driven toothed ring 43, the outer wall of the second crushing ring 42 is fixedly connected to a second driven toothed ring 44, the top of the first crushing ring 41 is rotatably connected to a first drive plate 62, and the bottom of the second crushing ring 42 is rotatably connected to a second drive plate 63.

[0030] By pulling the first drive plate 62 and the second drive plate 63, the first crushing ring 41 and the second crushing ring 42 can be lowered, so that the second crushing ring 42 moves to the position of the first crushing ring 41 and continues to crush the droplets, while the first crushing ring 41 remains stationary, and the powder attached to it loses centrifugal force and falls automatically.

[0031] Please see the appendix Figure 3 -Appendix Figure 5 The drive component 5 includes a geared motor 51, the output end of which is fixedly connected to a drive shaft 52. The drive shaft 52 is fitted with a first drive wheel 53 that meshes with the first driven gear ring 43 and a second drive wheel 54 that meshes with the second driven gear ring 44.

[0032] Please see the appendix Figure 6 -Appendix Figure 7 A drive disc 55 is fixedly connected to the drive shaft 52, and multiple linkage rods 56 are fixedly connected to the drive disc 55. Multiple drive holes 57 corresponding to the linkage rods 56 are opened on one side of the first drive wheel 53 and the second drive wheel 54.

[0033] Initially, the first crushing ring 41 begins to rotate. At this time, the lower linkage rod 56 enters the drive hole 57 of the first drive wheel 53. After the reduction motor 51 is turned on, it will drive the drive shaft 52 to rotate. The drive shaft 52 drives the drive disc 55 to rotate. By using the linkage rod 56 and the drive hole 57, power is transmitted to the first drive wheel 53. The first drive wheel 53 drives the first driven gear ring 43 to rotate, so that the first crushing ring 41 can rotate at the set speed. After a period of time, the first drive plate 62 and the second drive plate 63 descend, causing the second drive wheel 54 to move down. The drive hole 57 on it is inserted into the linkage rod 56, and the second drive wheel 54 begins to rotate, smoothly transmitting power to the second crushing ring 42 to continue crushing the droplets. At the same time, the drive hole 57 of the first drive wheel 53 separates from the corresponding linkage rod 56, losing transmission, causing the second crushing ring 42 to stop rotating quickly. Under the action of losing centrifugal force, the powder attached to the inner side of the helical teeth automatically falls off.

[0034] The linkage rod 56 includes a fixed cylinder 561, and a push rod 562 is slidably connected inside the fixed cylinder 561. A reset element, which is a reset spring, is fixedly connected to the bottom of the push rod 562 and the inner bottom of the fixed cylinder 561.

[0035] To ensure that the linkage rod 56 can be smoothly inserted into the drive hole 57, when the push rod touches the first drive wheel 53 or the second drive wheel 54, if it does not directly enter the drive hole 57, the push rod will automatically retract until it enters the drive hole 57 and is driven by the drive disc 55 to complete the power transmission.

[0036] Example 2 differs from Example 1 in that the following technical features are added: a liquid pushing component 7 is provided inside the centrifuge cylinder 32. The liquid pushing component 7 includes a hydraulic rod 71. A sealing plate 72 is fixedly connected to the bottom of the hydraulic rod 71. A pressure limiting valve is provided on the sealing plate 72. A liquid squeezing plate 73 is slidably connected inside the centrifuge cylinder 32. When the sealing plate 72 descends, it touches the liquid squeezing plate 73 to squeeze the liquid.

[0037] The squeezing plate 73 has a vent hole 74, and the bottom of the sealing plate 72 is provided with a sealing gasket. The inner wall of the vent hole 74 is fixedly connected to an annular plate 75. When the sealing gasket descends, it abuts against the annular plate 75, making the area below the squeezing plate 73 a sealed environment.

[0038] Specifically, a pull ring plate is fixedly connected to the squeezing plate 73, and multiple air holes (not shown in the figure) are opened on the pull ring plate. A push ring plate 76 is slidably connected to the outer wall of the hydraulic rod 71. The push ring plate 76 is slidably connected to the inside of the pull ring plate 77 and is confined inside it. When the hydraulic rod 71 is in the retracted state, the hydraulic rod 71 carries the push ring plate 76 to rise. Subsequently, it will also carry the squeezing plate 73 to rise through the pull ring plate 77, so that after each press is completed, the squeezing plate 73 can rise to the highest position.

[0039] Initially, the squeezing plate 73 is close to the inner top of the centrifuge cylinder 32. The sealing plate 72 has a vent hole 74. During centrifugation, the liquid is discharged normally from the liquid outlet 33 and centrifuged and atomized. After a period of time, the hydraulic rod 71 is opened, and the sealing plate 72 moves down to contact the annular plate 75, so that a large pressure is formed, squeezing the liquid downward and thus solving the problem of the liquid sliding down too slowly under high-speed centrifugation.

[0040] Specifically, the inner wall of the powder-making cylinder 2 is fixedly connected with multiple buckles (which are made of high-temperature resistant elastic metal). Initially, the buckles can support the squeezing plate 73, suspending it near the inner top of the centrifuge cylinder 32. When the hydraulic rod 71 is started, it first lowers the sealing plate 72, then breaks through the elastic force of the buckles, and finally moves the squeezing plate 73 down.

[0041] Working principle of the invention: First stage of crushing: During centrifugal atomization, the molten alloy powder liquid is first poured into the centrifuge cylinder 32, and the sealing cover 8 is covered. The gas filling pump fills the powder making cylinder 2 with inert gas through the pipeline and controls the content of inert gas inside to isolate the non-ferrous metal from contact with oxygen. Then the drive motor 31 is turned on, and the drive motor 31 drives the centrifuge cylinder 32 to rotate at high speed. Under the action of high-speed centrifugation, the liquid is thrown out from the liquid outlet 33 along the tangential. The high-speed centrifugal force pulls the liquid film into liquid filaments, and the liquid filaments are then pulled into tiny liquid droplets. Secondary crushing stage: The linkage rod 56 located below enters the drive hole 57 of the first drive wheel 53. After the reduction motor 51 is turned on, it will drive the drive shaft 52 to rotate. The drive shaft 52 drives the drive disc 55 to rotate. By using the linkage rod 56 and the drive hole 57, the power is transmitted to the first drive wheel 53. The first drive wheel 53 drives the first driven gear ring 43 to rotate, so that the first crushing ring 41 can rotate at the set speed. When the droplets are pulled into tiny droplets, they will collide with the helical teeth, automatically crush them and fall off. Because the droplets that have just been thrown out are very fast, the extended helical teeth are exactly on the trajectory of the droplet tangent. The collision causes the droplets to be further crushed, improving the fineness of the powder produced by the centrifugal atomization equipment. Exchange phase: The micro push rod 61 is activated, causing it to descend along with the first drive plate 62 and the second drive plate 63. Then, the second drive wheel 54 moves down, and its drive hole 57 is inserted into the linkage rod 56. The second drive wheel 54 is forced to rotate and transmits power smoothly to the second crushing ring 42 through the second driven tooth ring 44 to continue crushing the droplets. At the same time, the drive hole 57 of the first drive wheel 53 separates from the corresponding linkage rod 56, losing transmission. This causes the second crushing ring 42 to stop rotating quickly. Under the action of losing centrifugal force, the powder adhering to the inner side of the inclined teeth automatically falls off, completing the purpose of automatically cleaning the inner edge of the inclined teeth. During the liquid pushing stage: The squeezing plate 73 is located near the inner top of the centrifuge cylinder 32. The sealing plate 72 has a vent hole 74. During centrifugation, the liquid is discharged normally from the liquid outlet 33 for centrifugal atomization. During the exchange process, the flow control valve is closed and the hydraulic rod 71 is opened. The sealing plate 72 moves down and comes into contact with the annular plate 75, which creates a large pressure force, squeezing the liquid downward. Some gas is released from the pressure relief valve. When the hydraulic rod 71 is in the retracted state, the hydraulic rod 71 carries the push ring plate upward through the sealing plate 72. Subsequently, it will carry the squeezing plate 73 upward through the pull ring plate, so that after each downward press is completed, the squeezing plate 73 can rise to the highest point. Then the flow control valve is opened again. Repeated exchange stage: Subsequently, the micro push rod 61 can be activated again to extend it, pushing the first drive plate 62 and the second drive plate 63 to rise. At this time, the first crushing ring 41 rotates, the second crushing ring 42 is stationary, and the helical teeth on the first crushing ring 41 automatically contact the helical teeth on the second crushing ring 42 during rotation, completing the automatic cleaning of residual metal powder on the top surface.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
