Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0033] It's important to know that this atomizer tray is an auxiliary device for the atomizer, and the atomizer is typically placed and fixed in the center of the tray. Specifically, the solidified fine powder after atomization is carried along the inner wall of the atomizing chamber by the airflow from the bottom to the top. The atomizer tray mainly provides a vertically downward auxiliary airflow to form an air wall, thereby preventing the cooled, solidified fine powder from adhering to the molten metal droplets, forming satellite powder and irregularly shaped powder, thus improving the sphericity and flowability of the powder.

[0034] like Figures 1 to 6 As shown, this application provides a split-type atomizer tray, including an upper cover assembly 1 and a lower cover assembly 2; the upper cover assembly 1 includes an upper cover body 11 and a retaining ring 12; the upper cover body 11 is provided with at least two air inlet channels 113, the air inlet 112 of the air inlet channel 113 is protruding from the top of the upper cover body 11, and the air outlet 111 of the air inlet channel 113 is located at the bottom of the upper cover body 11; the retaining ring 12 is located at the bottom of the upper cover body 11 and is connected to the air outlet. The upper cover assembly 1 and the lower cover assembly 2 are detachably connected; the lower cover assembly 2 includes a lower cover body 21 and a rectifier ring 22; the fixing ring 12 abuts against the lower cover body 21, and the rectifier ring 22 is embedded in the upper cover assembly 1 and forms a gas chamber with the upper cover assembly 1; the gas chamber is connected to the air inlet channel 113; the lower cover body 21 is also provided with a plurality of nozzles 215, which are evenly arranged circumferentially and located in the gas chamber.

[0035] Furthermore, such as Figure 2As shown, the upper cover assembly 1 is provided with at least two air inlet channels 113 for multi-channel diversion. After mixing in the gas chamber, a uniform air curtain is output through the nozzle 215 to avoid unilateral airflow bias and ensure uniform gas distribution. The air inlet channel 113 has a raised air inlet 112 structure at the top of the upper cover assembly 1, which facilitates connection to the gas source pipeline and raises the position of the air inlet 112 to prevent liquid backflow. The fixing ring 12 abuts against the mounting groove 114 of the lower cover body 21 and forms a closed gas chamber with it to maintain the overall structural stability and prevent gas leakage. At the same time, it positions and fixes the relative positions of the upper cover assembly 1 and the lower cover assembly 2. Preferably, the diameter of the upper cover body 11 is larger than the diameter of the fixing ring 12, and the diameter of the fixing ring 12 is equal to the diameter of the lower cover body 21, forming a tight end face. The sealing contact ensures assembly accuracy and prevents gas leakage from the connection between the upper and lower covers. The gas outlet 111 is located at the bottom of the upper cover assembly 1 and close to the fixing ring 12, so that the gas is directly guided to the gas chamber. The rectifier ring 22 is fitted into the upper cover body 11 and forms a sealed gas chamber with it, providing a stable diffusion space for the airflow. Through the cooperation of the annular rectifier ring 22 with the gas chamber, the gas is buffered and pressure equalized in this chamber, eliminating turbulence and ensuring that the gas is evenly distributed to each nozzle 215. The multiple nozzles 215 are evenly distributed circumferentially and are directly impacted by the rectified airflow, shearing the liquid into tiny droplets and generating a vertically downward air curtain. This prevents the cooled and solidified fine powder from adhering to the molten metal droplets, forming satellite powder and irregular powder, thereby improving the sphericity and flowability of the powder.

[0036] Specifically, an external air source enters the air intake channel 113 through the protruding air inlet 112 and is injected into the gas chamber through the air outlet 111. Within the chamber, the gas is regulated by the rectifier ring 22, and after pressure equalization, it acts evenly on the nozzle 215 area. High-pressure gas is ejected at high speed from the nozzle 215, shearing the liquid (such as a medicinal liquid) flowing through the nozzle 215 and breaking it into atomized particles. In other words, the combination of multiple air intake channels 113, the rectifier ring 22, and the uniform nozzle 215 optimizes airflow utilization, resulting in fine and uniform atomized particles, achieving a stable, efficient, and easy-to-maintain auxiliary airflow function. The fixing ring 12 abuts against the lower cover body 21, and the rectifier ring 22 is embedded in the upper cover body 11, thus forming a double seal, enhancing structural stability while ensuring airtightness. The airflow parameters can be adjusted to adapt to media of different viscosities by replacing the rectifier ring 22 or the fixing ring 12 with different specifications. Furthermore, the upper cover assembly 1 and the lower cover assembly 2 are detachably connected, facilitating the cleaning of solidified powder.

[0037] It is important to know that the number of rotations of nozzle 215 is set to (1-5) rotations, including but not limited to (1-5) rotations; the spacing between adjacent air rings is (10-30) mm, and the number of nozzles 215 is between (10-30). The air output is jointly controlled by the pressure of the pressure reducing valve and the diameter of nozzle 215; the diameter of nozzle 215 is controlled within (1-15) mm; the included angle of the centerline of the angled nozzle 215 is within (20-70)°, that is, the axial direction of the annular air hole 221 forms a preset angle with the radial direction of the rectifier ring 22; the flow ratio of auxiliary airflow to atomized airflow needs to be greater than 0.7 to ensure smooth and uniform airflow distribution and avoid airflow turbulence or excessively strong local airflow.

[0038] In this embodiment, the protruding air inlet 112 is provided with an internal hexagonal blind hole for supporting quick replacement of straight or bent converters. It can be adapted to 304 stainless steel metal hose (high temperature resistance 800℃, burst pressure 5MPa) to achieve safe delivery of inert gas in high temperature smelting environment. The front end of the pre-installed metal hose is connected to a stainless steel pressure reducing valve and a pressure regulating system. The air inlet pressure can then be controlled to stabilize within the range of (0.5-1.8)MPa by adjusting the valve stem stroke, effectively suppressing the influence of pressure fluctuations on the main atomizing cone.

[0039] In this embodiment, as Figure 2 As shown, the sidewall of the rectifying ring 22 has multiple annular air holes 221 evenly distributed circumferentially, and the gas chamber is connected to the air intake channel 113 through the annular air holes 221. The annular air holes 221, evenly distributed circumferentially along the rectifying ring 22, divert the gas from the air intake channel 113 to different areas of the gas chamber in multiple directions, preventing concentrated airflow from impacting a portion of the nozzles 215, ensuring uniform pressure distribution within the chamber, and improving the gas-liquid contact efficiency. In other words, the design of adding annular air holes 221 to the sidewall of the rectifying ring 22 further optimizes the gas flow path and uniformity.

[0040] In this embodiment, the diameter of the rectifier ring 22 is smaller than the diameter of the lower cover body 21, forming an annular buffer zone at the edge of the gas chamber, so that the airflow is fully pressure-equalized before reaching the nozzle 215, avoiding uneven airflow distribution caused by positional differences in the circumferential nozzle 215; that is, an annular gap is formed between the outer peripheral wall of the rectifier ring 22 and the inner peripheral wall of the fixed ring 12, the annular air hole 221 communicates with the annular gap, and the air intake channel 113 communicates with the gas chamber through the annular gap, forming a continuous airflow channel.

[0041] Furthermore, the gas in the intake channel 113 first enters the annular gap, and then flows radially into the gas chamber through the annular air hole 221, forming a staged flow from the annular gap to the annular air hole 221 to the gas chamber, rather than being directly injected into the gas chamber. This disperses the airflow evenly along the circumference, avoiding single-point high-pressure impacts and preventing uneven chamber pressure caused by direct airflow injection. This gap acts as a buffer space, where the airflow decelerates and pressurizes, forming a stable air cushion that provides a balanced air source for the subsequent annular air hole 221 and nozzle 215. Preferably, the gas enters the chamber at a tangential angle through the annular air hole 221, forming a swirling flow upon contact with the liquid, thus improving shear efficiency. It is known that the flow guidance of the annular gap reduces pressure loss compared to the direct injection design, resulting in a higher atomization flow rate at the same input pressure.

[0042] It is clear that gas preferentially fills the annular gap to quickly establish system pressure; then, the airflow is continuously and stably injected into the chamber through the annular air holes 221 to maintain the atomization pressure of the nozzles 215. The annular air holes 221 act as flow control valves to regulate the amount and direction of gas entering the chamber. The annular gap ensures that gas enters the annular air holes 221 evenly, causing all nozzles 215 to experience consistent force, forming an annular air wall that covers the downward path of the condensed powder on the inner wall of the atomization chamber, resulting in a more concentrated particle size distribution. Even if individual nozzles 215 are temporarily blocked, the "air reservoir" effect of the annular gap can quickly replenish gas through other annular air holes 221, preventing atomization interruption.

[0043] In this embodiment, as Figure 3 As shown, the fixing ring 12 has a first sealing groove 121 on its end face facing the lower cover body 21, and a second sealing groove 211 is provided on the upper surface of the lower cover body 21 at a corresponding position. Preferably, the first sealing groove 121 and the second sealing groove 211 are usually annular grooves with a depth slightly greater than the diameter of the sealing ring cross section. When the upper cover assembly 1 is assembled with the lower cover assembly 2, the first sealing groove 121 and the second sealing groove 211 form a first sealing cavity. A first sealing ring is provided in the first sealing cavity. Preferably, the first sealing ring can be an O-ring fluororubber sealing ring, which is inserted into the internal thread blind hole with an internal hexagonal bolt to achieve the airtightness and low leakage rate of the assembly.

[0044] The double-groove structure acts as a guide when the upper cover assembly 1 and the lower cover assembly 2 are pressed together, preventing misalignment or extrusion of the sealing ring. Subsequently, the first sealing ring expands radially under the pressure of the upper and lower groove walls, simultaneously sealing the axial and radial micro-gaps between the fixing ring 12 and the lower cover body 21. When the pressure inside the gas chamber increases, the first sealing ring further deforms to enhance the seal, preventing high-pressure gas leakage. Furthermore, because this sealing structure is located on the side of the annular gap away from the gas chamber, it directly blocks the airflow from the gas chamber → the gap between the fixing ring 12 and the lower cover body 21 → to the external environment, preventing gas leakage. In other words, the double-sealing groove and sealing ring design between the fixing ring 12 and the lower cover body 21 further enhances the airtightness and assembly stability of the atomizer tray.

[0045] In this embodiment, as Figure 3 As shown, the upper cover body 11 is perforated by a first flow guide baffle 13, which is flush with the fixing ring 12 and located within the gas chamber. Furthermore, the first flow guide baffle 13 extends downwards from the top of the gas chamber and is flush with the end face of the fixing ring 12, dividing the chamber into multiple fan-shaped regions. This allows the airflow to enter through the annular air hole 221 and flow along the baffle, breaking the random vortices caused by free gas diffusion and forming an ordered axial and tangential composite flow. The height of the first flow guide baffle 13 is flush with the fixing ring 12, ensuring that the air pressure in each fan-shaped region is established synchronously. This guides the airflow to turn and flow horizontally towards the nozzle 215, enhancing the gas-liquid shear angle and preventing uneven atomization of the nozzle 215 due to local low-pressure areas. In other words, the first flow guide baffle 13 added to the upper cover body 11 further optimizes the flow field distribution within the gas chamber, significantly improving airflow uniformity and energy utilization through its synergistic effect with the fixing ring 12.

[0046] In this embodiment, as Figure 6As shown, the lower cover body 21 has a second flow guide baffle 216 extending through it. The second flow guide baffle 216 is connected to the first flow guide baffle 13 and is located outside the gas chamber. Furthermore, the height of the second guide baffle 216 is 100-400mm to adapt to different atomizing media; the height of the initial atomization area of ​​the atomizing cone is generally (50-200)mm. Setting the second guide baffle 216 can effectively prevent the initial atomized powder from sticking with the fine powder, while reducing the influence of the auxiliary airflow on the main atomizing airflow; specifically, the distance between the auxiliary airflow and the guide tube is (600-2000)mm (depending on the air pressure), and the inner and outer diameters of the auxiliary airflow are determined according to the position of the atomizer. Generally, the inner diameter is (100-200)mm and the outer diameter is (250-400)mm. By setting the second guide baffle 216, the particle collision area can be moved down by (500-1200)mm, and the powder at the subsequent height has basically solidified into a spherical shape and is no longer affected by the fine powder. That is, by setting the second guide baffle 216, the auxiliary airflow interference is blocked, the secondary airflow is prevented from disturbing the main atomization zone, and the powder sphericity is optimized.

[0047] In this embodiment, as Figure 2 As shown, the first flow guide baffle 13 has a third sealing groove 131 on its end face facing the lower cover body 21, and the lower cover body 21 has a fourth sealing groove 214 at the corresponding position; wherein the third sealing groove 131 and the fourth sealing groove 214 provide a fixing base groove for the second sealing ring, constraining the radial deformation direction of the sealing ring; when the first flow guide baffle 13 is assembled with the second flow guide baffle 216, the third sealing groove 131 and the fourth sealing groove 214 form a second sealing cavity to prevent the second sealing ring from moving axially, and the second sealing ring is provided in the second sealing cavity; preferably, the second sealing ring can be a fluororubber or metal-coated ring to adapt to the requirements of metal atomization or sterilization; to further improve the airtightness and flow field stability of the atomizer, especially suitable for high-pressure and high-precision atomization scenarios.

[0048] In this embodiment, as Figure 5 As shown, the lower cover body 21 is provided with a first partition 212. The first partition 212 is close to the first flow guide baffle 13 and is spaced apart from the nozzle 215. The first flow guide baffle 13 first coarsely adjusts the direction of the fluid, guiding the airflow towards the nozzle 215 to avoid direct impact on the nozzle 215 and causing turbulence. The first partition 212 is further refined to form a progressive flow guide structure. The distance between the first partition 212 and the first flow guide baffle 13 avoids direct impact of the fluid on the nozzle 215, reducing noise or wear.

[0049] In this embodiment, as Figure 5As shown, the lower cover body 21 is also provided with a second partition 213. The nozzle 215 is provided between the second partition 213 and the first partition 212 to reduce turbulence interference and ensure injection accuracy. It is also positioned close to the rectifier ring 22 to limit fluid disturbance around the nozzle 215 and ensure stable injection direction. The airflow disperses after impacting the first guide baffle 13, and some airflow is blocked by the first partition 212 and redirected towards the nozzle 215. Because the second partition 213 is high and the annular seam is closed by the ring, the airflow can only be ejected through the nozzle 215, forming a high-speed, concentrated airflow. The rectifier ring 22 further stabilizes the direction of the ejected airflow and reduces turbulence.

[0050] In this embodiment, as Figure 2 As shown, the height of the first baffle 212 is less than the height of the second baffle 213, forming a stepped height difference. The lower first baffle 212 allows some fluid to pass through, while the remaining fluid is blocked by the higher second baffle 213, forming a two-stage flow guide. This is used to separate fluids with different flow rates or pressures, and can form a precise airflow barrier, reducing the height of the particle collision zone.

[0051] It is understood that the baffle can control the opening and closing state of the nozzle 215 or the annular gap by placing or removing the stainless steel ring, thus achieving diversified air output methods. Specifically, when placing the ring, it fills the gap between the first baffle 212 / second baffle 213 and the rectifier ring 22, closing the annular gap and forcing the airflow to pass only through the nozzle 215 for concentrated spraying. When removing the ring, it opens the annular gap, allowing the airflow to pass through both the nozzle 215 and the annular gap simultaneously for dispersed flow. In other words, through the above-mentioned double baffle setup, the backflow path of fine metal powder is effectively blocked, significantly reducing unintended collisions between molten powders.
