Description

Technical Field

[0001] This invention relates to the field of magnetic powder core processing equipment, and more particularly to an aerosol generator. Background Technology

[0002] Metal powder cores, as a novel type of soft magnetic material, are widely used in inductors, reactors, and transformers, serving as an indispensable product in electronic materials. With the development of electronic devices towards higher frequencies and smaller sizes, the requirements for metal powder cores are also increasing. Like soft magnetic products, metal powder cores are also developing towards lower losses and higher saturation magnetic induction. Metal powder cores are obtained by insulating and coating metal powder, followed by high-pressure pressing and high-temperature heat treatment.

[0003] There are many methods for preparing metal magnetic powder, but the main ones are mechanical crushing, water atomization and gas atomization. Among them, the metal powder prepared by mechanical crushing and water atomization methods has irregular shape and good formability, but the surface of the metal magnetic powder is not easy to be coated with a film, the eddy current loss is high and the oxygen content is high.

[0004] When preparing magnetic powder cores using gas atomization, it is necessary to weigh the magnetic powder alloy according to the formula ratio in the early stage, and then melt it in a smelting furnace to form magnetic powder alloy molten steel. The magnetic powder alloy molten steel is then added into the atomizer. The atomizer uses high-speed airflow to impact the column of magnetic powder alloy molten steel and break it into tiny droplets. Subsequently, the tiny droplets are cooled and solidified into magnetic powder alloy solid particles.

[0005] However, existing aerosol generators cannot adjust the particle size of the prepared magnetic powder alloy solid particles as needed. Summary of the Invention

The ejected gas impacts and breaks up the molten magnetic alloy steel column, breaking it into tiny magnetic alloy droplets. These tiny droplets rapidly cool and solidify into fine magnetic alloy solid particles.

[0011] Preferably, the airflow regulating mechanism further includes: a reversible motor, whose power output shaft is fixedly connected to the top surface of the rotating disk; and a mounting plate, which is fixedly sleeved on the surface of the reversible motor, with one end of which is fixedly connected to the inner wall of the movable cylinder.

[0012] Preferably, the bottom surface of the hollow base is equidistantly equipped with electric actuators of the same number as the fixed cylinders, and the extension end of each electric actuator is fixedly connected to a connecting plate, which is fixedly sleeved on the surface of the movable cylinder.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] The aerosol generator of this invention comprises a cylinder, a hollow base, an air inlet pipe, multiple fixed cylinders, multiple movable cylinders, and multiple airflow regulating mechanisms. When molten magnetic alloy steel passes through the liquid passage of the hollow base, gas is introduced into the hollow base via the air inlet pipe. The gas inside the hollow base is then ejected by the movable cylinders. The ejected gas impacts and breaks up the molten magnetic alloy steel column into tiny magnetic alloy droplets. These tiny droplets rapidly cool and solidify into fine magnetic alloy solid particles. The airflow regulating mechanisms adjust the flow rate and velocity of the gas ejected through the movable cylinders. The flow rate and velocity affect the atomization of the liquid and the formation of particles; higher flow rates and velocities facilitate the formation of fine, spherical magnetic alloy solid particles. The flexible gas... The flow rate regulation method can improve the atomization effect. By setting up a fixed disk, a rotating disk, a rotating ring, and a forward and reverse motor, when the forward and reverse motor is running, the through groove on the rotating disk is connected to the first or second through hole. At the same time, the rotating disk and the connecting rod drive the rotating ring to rotate, thereby causing multiple baffles to open or close. When multiple baffles are open, the amount of gas ejected through the movable cylinder increases, and the diameter of the ejected gas is also smaller. The smaller diameter of the ejected gas can generate more liquid surface area, promoting better atomization and particle formation, thus facilitating the production of fine, spherical magnetic powder alloy solid particles. When multiple baffles are closed, the amount of gas ejected through the movable cylinder decreases, and the diameter of the ejected gas is also larger, thus facilitating the production of larger magnetic powder alloy solid particles.

[0030] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0031] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figures 1-5 As shown, an aerosol generator includes a cylinder 100, a hollow base 200, an air inlet pipe 210, multiple fixed cylinders 230, multiple movable cylinders 240, and multiple airflow regulating mechanisms 400.

[0034] A guide pipe 130 is installed through the top surface of the cylinder 100, and an intermediate liner 140 is installed on the top surface of the guide pipe 130. Multiple L-shaped plates are equidistantly arranged on the side of the cylinder 100. The L-shaped plates are installed on the side of the cylinder 100 by bolts, and a support leg 110 is fixedly connected to the bottom surface of the L-shaped plate. A discharge pipe 101 is installed on the bottom surface of the cylinder 100, and a sealing cap 102 is threadedly connected to the discharge pipe 101.

[0035] The hollow seat 200 is circular in shape. The center of the hollow seat 200 is the liquid passage. The bottom surface of the hollow seat 200 is inclined. The top of the hollow seat 200 is connected to the guide pipe 130. The liquid passage of the hollow seat 200 is connected to the guide pipe 130.

[0036] One end of the air inlet pipe 210 is fixedly connected to and communicates with the hollow seat 200, and the other end of the air inlet pipe 210 extends outside the cylinder 100.

[0037] Multiple fixed cylinders 230 are fixedly connected to and communicate with the hollow base 200, and the multiple fixed cylinders 230 are equidistantly arranged on the hollow base 200; the number of movable cylinders 240 is the same as that of the fixed cylinders 230, and the multiple movable cylinders 240 are slidably connected to the multiple fixed cylinders 230 respectively.

[0038] Multiple airflow regulating mechanisms 400 are respectively installed in multiple movable cylinders 240. The airflow regulating mechanism 400 is used to regulate the jet speed of the gas ejected through the movable cylinder 240.

[0039] Specifically, when molten magnetic powder alloy steel passes through the liquid passage of the hollow base 200, air is introduced into the air inlet pipe 210. The air inlet pipe 210 delivers gas into the hollow base 200. The gas inside the hollow base 200 enters the movable cylinder 240 through the fixed cylinder 230, and is then ejected by the movable cylinder 240. The ejected gas impacts and breaks up the column of molten magnetic powder alloy steel into tiny magnetic powder alloy droplets. These tiny droplets rapidly cool and solidify into fine, spherical magnetic powder alloy solid particles. The flow rate and velocity of the gas ejected through the movable cylinder 240 can be adjusted by the airflow regulating mechanism 400. The gas flow affects the atomization of the liquid and the formation of particles. The higher the gas flow rate and velocity, the easier it is to produce fine, spherical magnetic powder alloy solid particles. Flexible gas flow rate adjustment can promote atomization.

[0040] like Figures 7-10 As shown, the airflow regulating mechanism 400 includes a fixed disk 410, a rotating disk 420, a rotating ring 430, a fixed ring 440, a forward and reverse motor 450, and a mounting plate 451.

[0041] The fixed plate 410 is fixedly connected to the inner wall of the movable cylinder 240. Multiple sets of first through holes 411 and multiple sets of second through holes 412 are opened through the fixed plate 410. The number of sets of first through holes 411 is the same as the number of sets of second through holes 412. The number of second through holes 412 in a set is greater than the number of first through holes 411 in a set. The diameter of the first through holes 411 is greater than the diameter of the second through holes 412. The total cross-sectional area of ​​a set of first through holes 411 is greater than the total cross-sectional area of ​​a set of second through holes 412.

[0042] The rotating disk 420 is located above the fixed disk 410 and is rotatably connected to the inner wall of the movable cylinder 240. Multiple through slots 421 are provided on the rotating disk 420. The number of through slots 421 is the same as the number of sets of the first through holes 411. Multiple connecting rods 422 are installed on the top surface of the rotating disk 420.

[0043] The bottom surface of the rotating ring 430 is fixedly connected to multiple connecting rods 422; multiple strip-shaped grooves 431 are opened on the bottom surface of the rotating ring 430, and a first shaft 432 is slidably connected in the grooves 431. A baffle 433 is installed on the first shaft 432; when the multiple baffles 433 are closed, a circular air passage is formed between the multiple baffles 433; when the multiple baffles 433 are opened, an irregular air passage is formed in the area enclosed by the multiple baffles 433. The cross-sectional area of ​​the irregular air passage is larger than that of the circular air passage, and the irregular air passage is similar to a saw blade shape.

[0044] The fixed ring 440 is rotatably connected to the inner wall of the rotating ring 430. Multiple fixed rods 441 are installed on the top surface of the fixed ring 440. The other end of the fixed rods 441 is fixedly connected to the inner wall of the movable cylinder 240. The bottom surface of the fixed ring 440 is equipped with the same number of second shafts 442 as the baffles 433. The second shafts 442 pass through the baffles 433 and are rotatably connected to them.

[0045] The power output shaft of the reversible motor 450 is fixedly connected to the top surface of the rotating disk 420; the mounting plate 451 is fixedly sleeved on the surface of the reversible motor 450, and one end of the mounting plate 451 is fixedly connected to the inner wall of the movable cylinder 240.

[0046] Specifically, when the forward and reverse motor 450 is running, its power output shaft will drive the rotating disk 420 to rotate, so that the through groove 421 on the rotating disk 420 is connected to the first through hole 411 or the second through hole 412; and when the rotating disk 420 rotates, it will drive the rotating ring 430 to rotate through the connecting rod 422, thereby causing the first shaft 432 to move in the slide groove 431, thereby causing the baffle 433 to rotate, so that multiple baffles 433 can be opened or closed.

[0047] When the multiple baffles 433 are unfolded, the through groove 421 on the rotating disk 420 is connected to the second through hole 412. At this time, the cross-sectional area of ​​the air passage formed by the multiple baffles 433 is larger, the amount of gas ejected through the movable cylinder 240 increases, and the orifice diameter of the ejected gas is also smaller. The smaller orifice diameter of the ejected gas can generate more liquid surface area, promoting better atomization and particle formation, thus facilitating the production of smaller magnetic powder alloy solid particles. When the multiple baffles 433 are closed, the through groove 421 on the rotating disk 420 is connected to the first through hole 411. At this time, the cross-sectional area of ​​the circular air passage between the multiple baffles 433 is smaller, the amount of gas ejected through the movable cylinder 240 decreases, and the orifice diameter of the ejected gas is also larger, thus facilitating the production of larger magnetic powder alloy solid particles.

[0048] When using an atomizer to pulverize magnetic alloy steel: the magnetic alloy steel in the crucible is added into the tundish 140, and the magnetic alloy steel in the tundish 140 enters the guide pipe 130. The guide pipe 130 guides the magnetic alloy steel in the form of a liquid column to the liquid passage of the hollow seat 200.

[0049] When the molten magnetic powder alloy steel column passes through the liquid passage of the hollow seat 200, nitrogen gas is introduced into the air inlet pipe 210. The air inlet pipe 210 delivers the gas into the hollow seat 200. The gas in the hollow seat 200 enters the movable cylinder 240 through the fixed cylinder 230, and then the movable cylinder 240 ejects the gas. The ejected gas impacts and breaks the molten magnetic powder alloy steel column into tiny magnetic powder alloy droplets. The tiny magnetic powder alloy droplets cool rapidly and solidify into fine, spherical magnetic powder alloy solid particles. Under the influence of gravity, the fine, spherical magnetic powder alloy solid particles fall into the discharge pipe 101 of the cylinder 100.

[0050] Depending on the required particle size of the magnetic powder alloy solid particles, before pulverizing the magnetic powder alloy molten steel, a forward and reverse motor 450 can be started, causing the power output shaft of the forward and reverse motor 450 to drive the rotating disk 420 to rotate, so that the through groove 421 on the rotating disk 420 is connected to the first through hole 411 or the second through hole 412; and when the rotating disk 420 rotates, it will drive the rotating ring 430 to rotate through the connecting rod 422, thereby causing the first shaft 432 to move in the sliding groove 431, thereby causing the baffle 433 to rotate, so that multiple baffles 433 can be opened or closed.

[0051] When the multiple baffles 433 are unfolded, the through groove 421 on the rotating disk 420 connects with the second through hole 412. At this time, the cross-sectional area of ​​the air passage formed by the multiple baffles 433 is larger, the amount of gas ejected through the movable cylinder 240 increases, and the orifice diameter of the ejected gas is also smaller. The smaller orifice diameter of the ejected gas can generate more liquid surface area, promoting better atomization and particle formation, thus facilitating the production of magnetic powder alloy solid particles with smaller particle size. When the multiple baffles 433 are closed, the through groove 421 on the rotating disk 420 connects with the first through hole 411. At this time, the cross-sectional area of ​​the circular air passage between the multiple baffles 433 is smaller, the amount of gas ejected through the movable cylinder 240 decreases, and the orifice diameter of the ejected gas is also larger, thus facilitating the production of magnetic powder alloy solid particles with larger particle size.

[0052] Example 2

[0053] like Figures 3-6 As shown, while other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the bottom surface of the hollow base 200 is equidistantly equipped with electric push rods 250 in the same number as the fixed cylinder 230, and the extension end of the electric push rod 250 is fixedly connected to a connecting plate 251, which is fixedly sleeved on the surface of the movable cylinder 240.

[0054] Before atomizing the magnetic powder alloy steel: by activating multiple electric actuators 250, the extension ends of the electric actuators 250 drive the connecting plate 251 to move, thereby adjusting the position of the movable cylinder 240. Then, the lower ends of the multiple movable cylinders 240 are adjusted to different heights, so that the multiple movable cylinders 240 are evenly distributed in a spiral shape.

[0055] When atomizing molten magnetic powder alloy steel, as the molten magnetic powder alloy steel passes through the liquid passage of the hollow seat 200, the gas ejected from multiple movable cylinders 240 directly acts on the molten magnetic powder alloy steel column, thereby atomizing the molten magnetic powder alloy steel and breaking the molten magnetic powder alloy steel column into numerous tiny magnetic powder alloy droplets. Since the multiple movable cylinders 240 are evenly distributed in a spiral shape, the gas at different heights can block the splashing magnetic powder alloy droplets, effectively preventing the magnetic powder alloy droplets from flowing back or spraying back, forming adhesion or blockage.

[0056] Furthermore, since the movable cylinder 240 is set at an angle, when the lower end of the movable cylinder 240 is at a different position, the distance between the lower end of the multiple movable cylinders 240 and the magnetic powder alloy steel liquid column will also be different. This results in different impact and crushing capabilities of the gas ejected from the multiple movable cylinders 240 on the magnetic powder alloy steel liquid column. The closer the lower end of the movable cylinder 240 is to the magnetic powder alloy steel liquid column, the stronger the impact and crushing capability of the gas, and the smaller the particle size of the generated magnetic powder alloy solid particles.

[0057] Example 3

[0058] like Figures 1-6 As shown, while other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that the aerosol generator also includes multiple air valves 220, a rotating seat 300, an internal gear ring 301, an annular groove 302, multiple air nozzles 303, and a drive mechanism 120.

[0059] Multiple air valves 220 are equidistantly mounted on the outer wall of the hollow seat 200, and all air valves 220 communicate with the interior of the hollow seat 200. A rotating seat 300 is sleeved on the outer wall of the hollow seat 200, and the rotating seat 300 is rotatably connected to the hollow seat 200 and the cylinder 100. The rotating seat 300 has a cavity structure. An internal gear ring 301 is mounted on the portion of the rotating seat 300 located above the hollow seat 200. An annular groove 302 is formed on the inner wall of the rotating seat 300, and all air valves 220 pass through the annular groove 302. Multiple air nozzles 303 are equidistantly mounted on the bottom surface of the rotating seat 300, and the air nozzles 303 communicate with the interior of the rotating seat 300.

[0060] Specifically, when the air valve 220 is opened, the gas inside the hollow cylinder will enter the rotating seat 300 through the air valve 220 and the annular groove 302, and the gas inside the rotating seat 300 will be discharged through multiple air nozzles 303.

[0061] The drive mechanism 120 is installed on the inner bottom surface of the cylinder 100, and is used to drive the internal gear ring 301 to rotate. The drive mechanism 120 includes a drive motor 121 and a gear 122. The drive motor 121 is installed on the inner bottom surface of the cylinder 100; the gear 122 is fixedly sleeved on the power output shaft surface of the drive motor 121, and the gear 122 meshes with the internal gear ring 301.

[0062] When atomizing molten magnetic powder alloy steel: By opening multiple air valves 220, the gas inside the hollow cylinder enters the rotating seat 300 through the air valves 220 and the annular groove 302. The gas inside the rotating seat 300 is discharged through multiple air nozzles 303, and the gas discharged from the air nozzles 303 forms an air column. At the same time, by starting the drive motor 121, the power output shaft of the drive motor 121 drives the gear 122 to rotate, which in turn meshes and drives the internal gear ring 301 to rotate, which in turn drives the rotating seat 300 to rotate, which in turn drives the multiple air nozzles 303 to rotate. The multiple air nozzles 303 also spray air when rotating, so that the multiple air columns form an annular gas wall. This annular gas wall can block splashing magnetic powder alloy droplets and prevent the magnetic powder alloy droplets from falling and sticking to the inner wall of the cylinder 100.
