[0056] In summary, when one of the metal rods 2034 is smelted in the heating coil 204, the other metal rods 2034 are all located in the annular heat-insulating shell 2035, and the adjacent metal rods 2034 are blocked by the heat-insulating vertical plate 2036. At this time, the annular shielding plate 2032 is located inside the annular heat-insulating shell 2035 to shield and insulate the metal rods 2034 from above. After the smelting of the metal rods 2034 is completed, the rotating replacement component 201 and the lifting component 202 are used to drive the installation disk 2034 to rotate. 31 rotates. During the lifting and lowering process of the mounting disc 2031, the heat insulating vertical plate 2036 and the annular baffle plate 2032 move upward for a certain distance.

The top seat 2025 moves upward, driving the mounting disc 2031 and the metal material rod 2034 set thereon to move upward and be located above the heating coil 204. Then, the rotating replacement component 201 is used to rotate the mounting disc 2031, and the new metal material rod 2034 is located above the heating coil 204. The telescopic rod 2023 inside the lifting cylinder 2021 is extended, driving the metal material rod 2034 to move downward and be re-located in the heating coil 204, and the metal material rod 2034 is melted and processed.

[0061] In this embodiment, preferably, by using the rotating replacement component 201, after the previous metal material rod 2034 is smelted, the mounting disc 2031 can be rotated to change the position of the metal material rod 2034, so that the new metal material rod 2034 can be re-positioned in the heating coil 204 for smelting and processing, thereby reducing the trouble of manual replacement. The rotating replacement component 201 for changing the angle of the mounting disc 2031 includes:

[0062] The mounting shaft 2011 mounted on the upper surface of the mounting disc 2031 and rotatably connected to the top seat 2025 does not affect the rotation of the mounting shaft 2011 and the linear gear 2012.

The driving motor box 2014 consists of a heat-insulating shell and a driving motor, and will not be affected by the heating coil 204 .

[0064] In summary, when in use, multiple metal rods 2034 are installed in the rod holder 2033, one of the metal rods 2034 is located in the heating coil 204, the metal rod 2034 is smelted and processed, and the inert gas is converted into a high-speed airflow by the inert gas nozzle 102 to atomize the molten metal. After the smelting of this metal rod 2034 is completed, the telescopic rod 2023 in the lifting cylinder 2021 drives the mounting disc 2031 to move upward and separate from the heating coil 204, driving the motor box 2014 to work, driving the rotating gear 2013 to rotate, and the linear gear 2012 meshing with it rotates, driving the mounting disc 2031 to rotate. The new metal material rod 2034 is positioned above the heating coil 204, the drive motor box 2014 stops working, the mounting disc 2031 stops rotating, the telescopic rod 2023 inside the lifting cylinder 2021 extends out to drive the mounting disc 2031 and the metal material rod 2034 to move downward and be positioned in the heating coil 204, and the lifting cylinder 2021 stops working, thereby realizing automatic replacement of the metal material rod 2034. During the replacement process of the metal material rod 2034, the atomizing powder making equipment will not be shut down, thus reducing the shutdown cost, and there will be no leakage of inert gas due to the shutdown for replacing the material rod, thus increasing the safety of the entire powder making equipment and improving the powder making efficiency.

[0065] Embodiment 2

[0066] Reference Figure 7 , which is the second embodiment of the present invention.

[0067] In this embodiment, preferably, a pressurizing component 400 for pressurizing the inert gas is provided on the left side of the smelting furnace 101. By providing the pressurizing component 400, the initially introduced inert gas can be temporarily stored, and the internal space of the pressurizing box 401 can be changed to increase the internal pressure, so that the gas can reach the pressure for atomizing the molten metal at the moment of final discharge, and the situation that the inert gas pressure is insufficient at the beginning and the atomization effect of the molten metal will not be affected, the powder making quality is improved, and the pressurization process is safe and stable. The pressurizing component 400 includes:

[0068] A booster box 401 is located on the left side of the smelting furnace 101, and an air inlet pipe 402 is arranged between the booster box 401. A horizontal plate 403 supporting the booster box 401 is arranged on the surface of the booster box 401, and the horizontal plate 403 is fixed on the outer surface of the smelting furnace 101;

[0069] The piston plate 404 is located inside the boost box 401, and a driving screw 405 is installed on the upper surface of the piston plate 404. The lower end of the driving screw 405 is rotatably connected to the piston plate 404, and the upper end of the driving screw 405 passes through the boost box 401 and is exposed to the outside. A handwheel 406 is provided at the upper end of the driving screw 405, and the handwheel 406 can be replaced with an electric drive structure as needed. The left side of the boost box 401 is connected to the air pipe, and valves are provided on the air pipe and the air inlet pipe 402.

[0070] In summary, when in use, the inert gas supply system connected to the atomizing powder making equipment is connected. At the moment the inert gas supply system is turned on, the pressure of the inert gas discharged at the beginning is transmitted to the metal solution, and the gas pressure may be insufficient, which has a poor effect on the atomization of the metal solution and affects the powder making quality. Therefore, in order to maintain sufficient inert gas pressure, the inert gas provided by the inert gas supply system first enters the boosting box 401 through the air pipe, and the valve on the air inlet pipe 402 is closed to prevent the inert gas from being discharged when it does not reach sufficient pressure. At the same time, the driving screw 405 can be rotated to drive the piston plate 404 to move downward, thereby reducing the internal space of the boosting box 401 and increasing the pressure. When the pressure is sufficient, the valve on the air inlet pipe 402 is opened, and the pressure of the inert gas discharged instantly from the boosting box 401 is sufficient to meet the requirements of the atomization of the metal solution, thereby improving the atomization powder making quality of the molten metal.

A spherical seat 310 is provided on the inner circumferential surface of the annular guide rail 302 to support the lower end of the scraper rod 309, so as to support and fix the scraper rod 309.

[0078] In summary, when fine powder is discharged, the rotating motor 307 works, driving the rotating gear 308 to rotate, and driving the gear ring 306 meshing therewith to rotate. The gear ring 306 is installed on the annular sleeve 305, and the annular sleeve 305 drives the annular guide rail 302 to rotate. The supporting sleeve 303 supports the annular guide rail 302 without affecting the rotation of the annular guide rail 302. The rotation of the annular guide rail 302 drives the scraper rod 309 arranged on the inner surface to rotate against the inner wall of the atomizing tower 100, and the fine powder attached to the inner wall of the atomizing tower 100 is scraped off or accumulated while rotating, thereby increasing the overall weight of the accumulated fine powder.
