Abstract
Description
Technical Field

[0002] The purpose of the rare earth alloy performance testing doping device is to introduce unique electronic structure characteristics by doping rare earth elements, thereby accurately detecting and evaluating the performance changes of rare earth alloys in magnetic, electrical, and optical aspects, and providing key data support for material research and development and application.
[0003] Existing devices require a step-by-step process for doping and performance testing of rare earth alloys, resulting in a lengthy experimental cycle. This lengthy cycle is due to the physical isolation between the melting vessel and the testing unit. After the rare earth alloy is melted, the sample needs to be transferred from the melting vessel to the testing unit for performance testing. However, this transfer process is not carried out in a completely sealed or protected environment, making the sample susceptible to contamination during the transfer. Contamination not only affects the composition and performance of the rare earth alloy but also interferes with subsequent performance testing results, reducing the accuracy of the testing.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figure 1 - Figure 6This utility model provides an embodiment: a rare earth alloy performance testing doping device, including a testing platform 1, a material conveying module, a rotating module, and an integrated testing module; the material conveying module includes a first support 2 disposed on the upper end of the testing platform 1, a rotating motor 3 disposed on the side end of the first support 2, a storage cavity 4 for storing rare earth is opened in the first support 2, a bearing seat 5 is disposed on one inner wall of the storage cavity 4, a rotating shaft 6 is rotatably connected in the bearing seat 5, an auger blade 7 is disposed on the outer wall of the rotating shaft 6, one end of the rotating shaft 6 is connected to the rotating motor 3, and a discharge port 8 is opened at the bottom of the storage cavity 4; the rotating module includes a turntable 9 disposed in the testing platform 1, a support 10 is rotatably connected to the lower end of the turntable 9, a rotating motor 11 is disposed on the outer wall of the support 10, and the rotating motor 11 is connected to the turntable 9 through a transmission structure;The integrated detection module includes a heating unit and a detection cooling unit. The heating unit includes a crucible rack 12 mounted on the upper end of the turntable 9, on which a quartz melting crucible 13 adapted to the discharge port 8 is mounted. A high-temperature heater 14 is mounted on the lower side of the quartz melting crucible 13. The detection cooling unit includes a second support 15 and a third support 16 mounted on the upper end of the detection platform 1. A transparent protective frame 17 is mounted on the lower end of the second support 15, and a laser spectral probe 18 is mounted inside the protective frame 17. A spray structure is mounted on the lower end of the third support 16, and the spray structure is connected to an external liquid nitrogen source through a pipe. The first support 2 serves as the input... The supporting structure of the material module provides an installation base for the rotary motor 3 and the storage cavity 4. The rotary motor 3 provides power for the rotation of the rotating shaft 6. When the rotary motor 3 starts, it drives the rotating shaft 6 to rotate, thereby causing the auger blades 7 to rotate. The rotation of the auger blades 7 transports the rare earth material in the storage cavity 4 out through the discharge port 8 at the bottom of the storage cavity 4, achieving stable transportation of the rare earth material. The discharge port 8 is the channel for the rare earth material to be output from the storage cavity 4, accurately transporting the rare earth material to the quartz melting crucible 13, thereby fusing it with the alloy in the quartz melting crucible 13. The turntable 9 serves as a platform supporting the quartz melting crucible 13, rotating... Driven by motor 11, the crucible rotates to operate the quartz melting crucible 13 at different positions. Crucible rack 12 is used to fix the quartz melting crucible 13, ensuring its stability during heating and testing. The quartz melting crucible 13 contains rare earth materials fed from outlet 8 and melts the rare earth materials and alloys under the action of high-temperature heater 14, preparing for subsequent performance testing. High-temperature heater 14 provides a high-temperature environment for the quartz melting crucible 13, enabling the rare earth materials to reach the melting temperature and achieving the preparation of rare earth alloys. Second bracket 15 serves as a protective frame for frame 17 and laser. The laser spectrometer 18 provides mounting support, and the protective frame 17 is made of transparent material, which protects the laser spectrometer 18 from external environmental influences while allowing it to clearly detect the rare earth alloy inside the quartz melting crucible 13. The laser spectrometer 18 detects the composition and properties of the rare earth alloy inside the quartz melting crucible 13 by emitting laser light and analyzing the reflected spectrum. The third bracket 16 provides mounting support for the spray structure, which is connected to an external liquid nitrogen source via a pipe. After detection, liquid nitrogen is sprayed onto the rare earth alloy inside the quartz melting crucible 13 for rapid cooling.
[0024] Please see Figure 3 and Figure 6In this embodiment, the transmission structure includes a drive gear 19 mounted on the outer wall of the output shaft of the rotary motor 3. A main shaft 20 is located at the lower end of the turntable 9. The main shaft 20 is connected to the support 10 via bearings. A driven gear 21 is located on the outer wall of the main shaft 20. The drive gear 19 meshes with the driven gear 21. The spray structure includes a retaining ring 22 fixed to the lower end of the third bracket 16. A cooling pipe 23 is located inside the retaining ring 22, and a cooling nozzle 24 is located at the outlet of the cooling pipe 23. The drive gear 19, mounted on the outer wall of the output shaft of the rotary motor 3, is the power source for the transmission structure. When the rotary motor 3 starts, the drive gear 19 rotates accordingly. Power is transmitted through gear meshing. The main shaft 20 is connected to the support 10 through bearings to ensure the stability of the main shaft 20 during rotation. The driven gear 21 is set on the outer wall of the main shaft 20 and meshes with the driving gear 19. When the driving gear 19 rotates, the driven gear 21 drives the main shaft 20 to rotate under the action of gear meshing, thereby realizing the power transmission from the rotary motor 3 to the turntable 9. The retaining ring 22 is used to fix and support the cooling pipe 23. Liquid nitrogen flows inside the cooling pipe 23 and is transported to the cooling nozzle 24 through the pipeline. The cooling nozzle 24 is responsible for spraying the liquid nitrogen evenly on the rare earth alloy in the form of a spray, thereby quickly reducing the temperature of the rare earth alloy.
[0025] Please see Figure 1 , Figure 2 and Figure 4In this embodiment, the inner wall of the storage cavity 4 is provided with an inclined plate 28, the lowest point of which is higher than the highest point of the auger blade 7. The second support 15 and the third support 16 are detachably connected to the testing platform 1 by bolts, and their heights are adjustable. The upper surface of the turntable 9 is provided with a positioning groove 25, and the bottom of the crucible rack 12 is provided with a positioning protrusion 26 that matches the positioning groove 25. The positioning protrusion 26 is inserted into the positioning groove 25. The lower end of the testing platform 1 is provided with a support leg 27, and the bottom of the support leg 27 is provided with a rubber pad. The storage cavity 4 is a space for storing rare earth materials, and its inner wall is specially provided with an inclined plate 28. The inclined plate 28 allows the rare earth materials in the storage cavity 4 to flow more smoothly and avoid accumulation. The lowest point of the inclined plate 28 is carefully set higher than the highest point of the auger blade 7. This design ensures that the auger blade 7 can rotate smoothly. Rare earth materials are effectively transported from the bottom of the storage chamber 4 without being obstructed by the inclined plate 28. The second bracket 15 and the third bracket 16 are detachably connected to the testing table 1 by bolts. This connection method facilitates the installation and disassembly of the second bracket 15 and the third bracket 16, and also makes it easy to maintain and replace the second bracket 15 and the third bracket 16. At the same time, the height of the second bracket 15 and the third bracket 16 is adjustable, and the height can be adjusted according to different testing needs. The positioning groove 25 enables the crucible rack 12 to be accurately positioned on the turntable 9. When the crucible rack 12 is placed on the turntable 9, the positioning protrusion 26 will insert into the positioning groove 25 to achieve a stable connection between the crucible rack 12 and the turntable 9. The bottom of the support leg 27 is also equipped with a rubber pad. The rubber pad has good elasticity and anti-slip performance, which can effectively reduce the vibration generated by the testing table 1 during use.
[0026] Working principle: First, rare earth materials are placed in storage chamber 4. The inclined plate 28 on the inner wall of storage chamber 4 ensures that the rare earth materials can flow smoothly. The rotary motor 3 is started. The rotation of the rotary motor 3 drives the rotating shaft 6 to rotate. The auger blades 7 rotate accordingly, and the rare earth materials in storage chamber 4 are stably transported from the discharge port 8 to the quartz melting crucible 13 to fuse with the alloy in the quartz melting crucible 13. Then, the rotary motor 11 is started. The rotary motor 11 drives the drive gear 19 to rotate. Through gear meshing, the power is transmitted to the driven gear 21, which in turn drives the main shaft 20 and the turntable 9 to rotate.
[0027] Next, the high-temperature heater 14 provides a high-temperature environment for the quartz melting crucible 13, so that the rare earth materials and alloys reach the melting temperature and the rare earth alloy is prepared. After melting, the laser spectral probe 18 under the second support 15 emits a laser and analyzes the reflected spectrum to detect the composition and properties of the rare earth alloy in the quartz melting crucible 13. After the detection is completed, the turntable 9 rotates. At this time, the spray structure under the third support 16 starts to work. Liquid nitrogen is transported to the cooling nozzle 24 through the cooling pipe 23 and sprayed evenly on the rare earth alloy in the form of a spray to cool it quickly.
[0028] Through the above steps, rare earth is stably transported using the feeding module, achieving precise mixing with the alloy. The rotating and integrated detection modules work together to provide a high-temperature melting environment and rapid cooling. Compared with traditional methods, this shortens the detection cycle and improves accuracy. It solves the problem that existing devices are prone to contamination during sample transfer due to the physical isolation between the melting container and the detection unit, resulting in long experimental cycles and reduced accuracy for rare earth alloy doping and performance testing.
