Description

Technical Field

[0001] The invention relates to the technical field of alloy powder preparation, in particular to a device for preparing multi-component spherical alloy powder. Background Art

[0002] In the field of preparation of multi-component spherical alloy powders, existing preparation devices usually use fixed atomizing nozzles and static guide structures to atomize molten metal liquid into powder. The basic working principle of these devices is to spray the molten metal liquid into tiny droplets through high-pressure gas and solidify into powder during cooling. However, this traditional preparation method has some significant defects:

[0003] First, since the atomizing nozzle and the guide structure are fixed, they cannot be dynamically adjusted according to the flow state of the molten metal liquid and the atomization requirements. This results in the molten metal liquid often being subjected to local excessive impact during the atomization process, resulting in droplet deformation and irregularly shaped particles. These defective particles not only affect the uniformity and quality of the alloy powder, but also reduce the recovery rate of fine powder and increase production costs.

[0004] Secondly, the air flow direction and the movement trajectory of the atomized liquid alloy in the existing device are often single, and cannot fully cover the molten liquid surface, which results in that part of the molten metal liquid cannot be effectively atomized, further affecting the preparation efficiency and quality of the alloy powder. At the same time, the single air flow direction may also lead to the formation of air flow dead corners and vortices, increasing the instability and uncertainty in the powder preparation process.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: Combination Figure 1-Figure 8 As shown, the present invention provides a technical solution: a preparation device for multi-component spherical alloy powder, the device comprising a main shell 1, the internal space of the shell 1 is designed to have an inner cavity, and a row of movable plates 2 are respectively arranged on both sides of the inner cavity, and these movable plates 2 are cleverly staggered to ensure that the alloy powder particles can be effectively shaped during the working process, and the top of each movable plate 2 is equipped with a shaping component 3, the function of these shaping components 3 is to promote the mutual collision between the alloy powder particles, so as to achieve the purpose of shaping;

[0029] The top of the shell 1 is designed with a feed port 11, which is specially used to receive the liquid alloy. In order to ensure that the liquid alloy can smoothly enter the shell 1, the feed port 11 is set at the top of the shell 1. At the bottom of the shell 1, a discharge port 12 is designed. The function of the discharge port 12 is to discharge the alloy powder particles that have been shaped. In order to achieve the atomization of the liquid alloy, an atomizing nozzle 13 is also specially arranged at the bottom of the feed port 11. The atomizing nozzle 13 can spray high-speed gas, and use the kinetic energy and shear force of the gas to atomize the liquid alloy into fine droplets. In the process of the liquid alloy falling, these fine droplets gradually cool and eventually form alloy powder particles;

[0030] The atomizing nozzle 13 is precisely mounted on the top inner wall of the housing 1, and is located directly below the feed port 11. In actual use, the atomizing nozzle 13 can spray gas. When the high-speed flowing gas contacts the surface of the liquid alloy, the liquid alloy is broken into fine droplets due to the extremely high kinetic energy and shear force of the gas, thereby completing the atomization of the liquid alloy. In order to further improve the atomization effect, the gas can be an inert gas, such as argon, helium, etc. Due to the chemical stability of the inert gas, they will not react chemically with the liquid alloy during the atomization process, thereby ensuring the purity of the liquid alloy during the atomization process;

[0031] The design of the shaping component 3 is very clever. It includes a semicircular plate 31 fixedly mounted on the top of the movable plate 2. A plurality of strong fixing rods 32 are fixedly connected to the side wall of the semicircular plate 31. Rectangular grooves 34 are formed around the outer walls of the fixing rods 32. The outer ends of the rectangular grooves 34 are fixedly connected to the mounting frame 35. The mounting frame 35 is provided with a connecting rod 36. The outer end of the connecting rod 36 is fixedly connected to an extension rod 37. The outer wall of the extension rod 37 is provided with a plurality of baffle rods 38. The function of the baffle rods 38 is to adjust the airflow and the motion trajectory of the atomized liquid alloy.

[0032] A first slide groove 39 is provided on the surface of the connecting rod 36, and a slide rod 310 is slidably connected in the first slide groove 39. The slide rod 310 can be rotatably mounted on the mounting frame 35, so that the slide rod 310 can slide freely on the connecting rod 36. A sleeve rod 311 is rotatably connected to the inner side end of the connecting rod 36, and the sleeve rod 311 is connected to the rotating rod 33 through a thread. This design allows the sleeve rod 311 to flexibly cooperate with the rotating rod 33, thereby realizing precise motion control;

[0033] A servo motor 312 is fixedly installed inside the semicircular plate 31, and an output end of the servo motor 312 is fixedly connected to a driving bevel gear 313. One end of the rotating rod 33 extends into the semicircular plate 31 and is fixedly connected to a driven bevel gear 314 meshing with the driving bevel gear 313. By turning on the servo motor 312, the driving bevel gear 313 can be driven to rotate synchronously. When the driving bevel gear 313 rotates, it will drive the meshing driven bevel gear 314 to rotate synchronously, so that the driven bevel gear 314 drives the rotating rod 33 to rotate synchronously;

[0034] When the rotating rod 33 rotates, it drives the sleeve rod 311 to move back and forth, so that the sleeve rod 311 drives the connecting rod 36 and the extension rod 37 to swing back and forth with the slide rod 310 on the mounting frame 35 as the axis. This reciprocating swing further drives the baffle rod 38 on the extension rod 37 to swing back and forth. In this way, the angle between the extension rod 37, the baffle rod 38 and the atomizing nozzle 13 can be continuously changed, thereby realizing precise control of the airflow and the motion trajectory of the atomized liquid alloy.

[0035] The shape of the baffle rod 38 should be optimized according to the airflow direction and the movement trajectory of the atomized liquid alloy. For example, a streamlined design can be adopted to reduce airflow resistance, or a multi-prism shape can be adopted to increase the airflow dispersion effect. The arrangement of the baffle rod 38 should ensure that the airflow and the atomized liquid alloy can be evenly distributed on the entire fixed rod 32, the extension rod 37, and the baffle rod 38 to avoid local excessive impact or airflow dead corners;

[0036] In practical applications, by arranging a plurality of fixed rods 32, extension rods 37, and baffle rods 38 below the atomizing nozzle 13, the quality and performance of the alloy powder can be significantly improved. These fixed rods 32, extension rods 37, and baffle rods 38 can effectively reduce the generation of defects such as satellite balls and dumbbell shapes, and improve the fine powder recovery rate and the uniformity of the powder. Through this carefully designed shaping component 3, the movement trajectory of the airflow and the liquid alloy during the atomization process can be accurately controlled, thereby obtaining high-quality alloy powder;

[0037] On both sides of the inner wall of the shell 1, support frames 315 are fixedly installed, and these support frames 315 are rotatably connected to the installation shafts 316. The inner ends of the installation shafts 316 are fixedly connected to the driving gears 318, and the outer ends of the installation shafts 316 are connected through synchronous belt transmission parts 327. One end of one of the installation shafts 316 is provided with a driving motor 317, and the driving gear 318 is rotatably connected to the connecting rod 319 at a position deviating from the center of the circle. The other end of the connecting rod 319 is rotatably connected to the first driving rod 320, and the first driving rod 320 is connected to the bottom of the movable plate 2. One side of the driving gear 318 is provided with a swing rod 324 rotatably installed on the inner wall of the shell 1, and the surface of the swing rod 324 A second slide slot 325 is provided, and the other end of the swing rod 324 is rotatably connected to the second driving rod 326. The second driving rod 326 is connected to the middle position of the movable plate 2. The top of the support frame 315 is rotatably connected to a driven gear 321 meshing with the driving gear 318. The axis of the driven gear 321 is fixedly connected to the rotating rod 322. The other end of the rotating rod 322 is rotatably connected to the control block 323. The control block 323 is slidably installed in the second slide slot 325. By turning on the driving motor 317, the installation shaft 316 is driven to rotate synchronously. The installation shaft 316 drives the installation shaft 316 on the other side to rotate synchronously through the synchronous belt pulley transmission member 327. The installation shaft 316 drives the driving gear The wheels 318 rotate synchronously, the driving gear 318 drives the connecting rod 319 to move back and forth, and the connecting rod 319 cooperates with the first driving rod 320 to drive the movable plate 2, the semicircular plate 31, and the fixed rod 32 to swing back and forth with the second driving rod 326 as the axis. At the same time, the driving gear 318 drives the driven gear 321 to rotate synchronously when it rotates. When the driven gear 321 drives the rotating rod 322 and the control block 323 to rotate synchronously, the control block 323 slides back and forth in the second sliding groove 325 during the rotation process, which in turn drives the swing rod 324 to swing back and forth with one end as the axis, and the swing rod 324 drives the second driving rod 326, the movable plate 2, the semicircular plate 31, and the fixed rod 32 at the other end to swing back and forth. Move up and down, so that the fixed rod 32, the extension rod 37, and the baffle rod 38 can also move up and down. This continuous adjustment allows the positional relationship between the fixed rod 32, the extension rod 37, the baffle rod 38 and the atomizing nozzle 13 to be adjusted. The gas ejected from the atomizing nozzle 13 contacts and collides with the fixed rod 32, the extension rod 37, and the baffle rod 38 in the form of atomized liquid alloy. The high-speed airflow changes direction and decays in speed when it hits the fixed rod 32, the extension rod 37, and the baffle rod 38. These changes form airflow branches in multiple directions. These branch airflows can impact the molten liquid surface more evenly. In this way, droplet deformation and the generation of irregularly shaped particles caused by local excessive impact can be reduced.

[0038] In the embodiment of the present invention, by starting the driving motor 317, the motor can drive the installation shaft 316 to rotate synchronously. The installation shaft 316 further drives the installation shaft 316 on the other side to rotate synchronously through the action of the synchronous belt pulley transmission member 327. As the installation shaft 316 rotates, the driving gear 318 also starts to rotate synchronously. The driving gear 318 is connected to the connecting rod 319, so that the connecting rod 319 can move back and forth. The connecting rod 319 drives the movable plate 2, the semicircular plate 31, and the fixed rod 32 to swing back and forth with the second driving rod 326 as the axis by cooperating with the action of the first driving rod 320. At the same time, the driving gear 318 will also drive the driven gear 321 to rotate synchronously during the rotation process. The driven gear 321 is connected to the rotating rod 322 and the control block 323, so that they can rotate synchronously. The control block 323 is located in the second slide groove during the rotation process. 325, reciprocating sliding, thereby driving the swing rod 324 to swing back and forth with one end as the axis, the other end of the swing rod 324 is connected to the second driving rod 326, the movable plate 2, the semicircular plate 31, and the fixed rod 32, so that these components can move up and down, and this up and down movement can further drive the fixed rod 32, the extension rod 37, and the baffle rod 38 to move up and down, thereby continuously adjusting the positional relationship between them and the atomizing nozzle 13, such adjustment enables the gas ejected from the atomizing nozzle 13 to contact and collide with the fixed rod 32, the extension rod 37, and the baffle rod 38 in the form of atomized liquid alloy, and when the high-speed airflow hits the fixed rod 32, the extension rod 37, and the baffle rod 38, the direction changes and the speed decays, forming airflow branches in multiple directions, and these branch airflows can impact the molten liquid surface more evenly, effectively reducing the droplet deformation and the generation of irregular-shaped particles caused by local excessive impact,

[0039] Next, by starting the servo motor 312, the motor can drive the active bevel gear 313 to rotate synchronously, and the active bevel gear 313 is meshed with the driven bevel gear 314, so that the driven bevel gear 314 can also rotate synchronously, and the driven bevel gear 314 is connected to the rotating rod 33, so that the rotating rod 33 can drive the sleeve rod 311 to reciprocate when rotating, and the sleeve rod 311 reciprocates through the connecting rod 36 and the extension rod 37, with the slide rod 310 on the mounting frame 35 as the axis, thereby driving the baffle rod 38 on the extension rod 37 to reciprocate, and this reciprocating swing can continuously change the angle between the extension rod 37, the baffle rod 38 and the atomizing nozzle 13, thereby optimizing the airflow direction and the atomizing liquid In order to reduce the airflow resistance, the baffle rod 38 can be streamlined, or can be a polygonal prism to increase the airflow dispersion effect. The arrangement of the baffle rod 38 should ensure that the airflow and the atomized liquid alloy can be evenly distributed on the entire fixed rod 32, the extension rod 37, and the baffle rod 38 to avoid local excessive impact or airflow dead corners. In practical applications, by arranging a number of fixed rods 32, extension rods 37, and baffle rods 38 under the atomizing nozzle 13, the quality and performance of the alloy powder can be significantly improved. These fixed rods 32, extension rods 37, and baffle rods 38 can effectively reduce the generation of defects such as satellite balls and dumbbell shapes, and improve the fine powder recovery rate and the uniformity of the powder.

[0040] Working principle of the preparation device for multi-component spherical alloy powder:

[0041] Step 1: First, liquid alloy is injected into the housing 1 through the feed port 11. During the injection of the liquid alloy, gas is simultaneously charged into the atomizing chamber through the atomizing nozzle 13. The gas atomizes the liquid alloy. The atomized liquid alloy gradually cools down during the falling process and forms alloy powder particles.

[0042] Step 2, turn on the driving motor 317 at the same time to drive the installation shaft 316 to rotate synchronously, the installation shaft 316 drives the installation shaft 316 on the other side to rotate synchronously through the synchronous belt pulley transmission member 327, the installation shaft 316 drives the driving gear 318 to rotate synchronously, the driving gear 318 drives the connecting rod 319 to move back and forth, so that the connecting rod 319 cooperates with the first driving rod 320 to drive the movable plate 2, the semicircular plate 31, and the fixed rod 32 to swing back and forth with the second driving rod 326 as the axis. At the same time, the driving gear 318 drives the driven gear 321 to rotate synchronously when rotating, and the driven gear 321 drives the rotating rod 322 and the control block 323 to rotate synchronously, and the control block 323 is located in the second slide groove 325 during the rotation process. Reciprocating sliding, thereby driving the swing The rod 324 reciprocates with one end as the axis, thereby driving the second driving rod 326, the movable plate 2, the semicircular plate 31, and the fixed rod 32 at the other end to move up and down, thereby driving the fixed rod 32, the extension rod 37, and the baffle rod 38 to move up and down, and then continuously adjusting the positional relationship with the atomizing nozzle 13, so that the gas sprayed by the atomizing nozzle 13 to atomize the liquid alloy contacts and collides with the fixed rod 32, the extension rod 37, and the baffle rod 38, and the high-speed airflow changes direction and decays in speed when hitting the fixed rod 32, the extension rod 37, and the baffle rod 38, forming airflow branches in multiple directions, and these branch airflows can impact the molten liquid surface more evenly, reducing the droplet deformation and irregular particle generation caused by local excessive impact;

[0043] Step three, then turn on the servo motor 312 to drive the active bevel gear 313 to rotate synchronously, the active bevel gear 313 drives the meshing driven bevel gear 314 to rotate synchronously, the driven bevel gear 314 drives the rotating rod 33 to rotate synchronously, and the rotating rod 33 drives the sleeve rod 311 to move back and forth when rotating, so that the sleeve rod 311 drives the connecting rod 36 and the extension rod 37 to swing back and forth with the slide rod 310 on the mounting frame 35 as the axis, and then drives the baffle rod 38 on the extension rod 37 to swing back and forth, thereby continuously changing the angle between the extension rod 37, the baffle rod 38 and the atomizing nozzle 13, and the shape of the baffle rod 38 should be optimized according to the airflow direction and the motion trajectory of the atomized liquid alloy. For example, a streamlined design can be used to reduce airflow resistance, or a multi-prism shape can be used to increase the airflow dispersion effect. The arrangement of the baffle rod 38 should ensure that the airflow and the atomized liquid alloy can be evenly distributed on the entire fixed rod 32, the extension rod 37, and the baffle rod 38 to avoid local excessive impact or airflow dead corners. In practical applications, the quality and performance of the alloy powder can be significantly improved by arranging a number of fixed rods 32, extension rods 37, and baffle rods 38 under the atomizing nozzle 13. These fixed rods 32, extension rods 37, and baffle rods 38 can effectively reduce the generation of defects such as satellite balls and dumbbell shapes, and improve the fine powder recovery rate and the uniformity of the powder.
