Description

Technical Field

[0001] This invention belongs to the field of furnace technology, specifically a high-pressure floating zone furnace for anisotropic UCM superconducting materials and its control method. Background Technology

[0002] The high-pressure floating zone furnace for anisotropic UCM superconducting materials is an advanced device specifically designed for growing high-melting-point, complex-structure superconducting materials. It achieves stable control of the molten zone through vertical optical path focusing heating, eliminating the need for a crucible. Its core parameters include a maximum growth temperature of 3000℃, a material growth chamber pressure of 300 bar, and 10⁻⁻⁶ bar. 5 The mbar high vacuum environment supports independent control of multiple gas atmospheres and can accurately simulate the material growth process under extreme conditions. This equipment is widely used in superconducting materials (such as nickel oxide and lanthanide copper oxide), magnetic materials, thermoelectric materials and quantum materials. It provides key technical support for the study of high-temperature superconducting mechanisms, topological states and strongly correlated electron systems. It is the core equipment for preparing high-quality single crystal samples and helps to break through the electromagnetic performance limits of traditional materials.

[0003] After the material growth is completed, the slag in the existing high-pressure floating zone furnace tends to accumulate in the furnace cavity, which requires manual removal and cleaning using tools. This method is not only labor-intensive and inefficient, but also easily damages precision components. Moreover, the cleaning effect is affected by the operator's skill level, and it is difficult to guarantee thorough cleaning. Summary of the Invention

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Example 1, by Figures 1 to 7The present invention includes a base plate 1, on the top of which a high-pressure floating zone furnace body 2 is fixedly mounted. The base plate 1 is supported by the ground to ensure the overall stability of the furnace. A support frame 4 is fixedly mounted on the rear side of the top of the high-pressure floating zone furnace body 2. An external hinged door 3 and a sliding door 7 are respectively movably mounted on the front and rear ends of the high-pressure floating zone furnace body 2. Opening the external hinged door 3 and the sliding door 7 can open the high-pressure floating zone furnace body 2. A connecting frame 5 is fixedly mounted on the top of the support frame 4. A servo motor 6 is fixedly mounted on one side of the connecting frame 5. The servo motor 6 can output rotational power accurately and stably. A push plate 9 and a rotating ring 10 are provided between the sliding door 7 and the support frame 4. The push plate 9 can move to push out slag. A dust-free brush 8 is fixedly mounted on the surface of the rotating ring 10. The dust-free brush 8 can clean the dust on the furnace wall, and its surface will not be covered with dust. A transmission component is provided at the output end of the servo motor 6. The transmission component is connected to the push plate 9 and the dust-free brush 8. When the servo motor 6 is running, it can drive the push plate 9 to move horizontally through the transmission component and drive the dust-free brush 8 to move and rotate.

[0035] After the high-pressure floating zone furnace body 2 completes the processing of the heterogeneous UCM superconducting material, the operator opens the outer door 3 and the sliding door 7; the operator controls the servo motor 6 to drive the transmission component to operate, and when the transmission component operates, it drives the push plate 9 to move into the interior of the high-pressure floating zone furnace body 2 to push the slag out from the outer door 3.

[0036] At the same time, the transmission component will also drive the dust-free brush 8 to rotate, so that the dust-free brush 8 will rotate and clean the slag and ash remaining on its inner wall while moving inside the high-pressure floating zone furnace body 2; this allows the high-pressure floating zone furnace to quickly and conveniently push out the slag accumulated in the furnace and clean the slag and ash attached to the inner wall without manual intervention, thereby reducing the workload of operators, improving work efficiency, and having an effective cleaning effect.

[0037] In Embodiment 2, based on Embodiment 1, the transmission assembly includes a drive shaft 14 fixedly installed at the output end of the servo motor 6. The surface of the drive shaft 14 is rotatably connected to the support frame 4 via an upper bearing 15. The upper bearing 15 enables the rotational positioning of the drive shaft 14. One end of the drive shaft 14 extends through to the other side of the support frame 4 and is fixedly mounted with an upper sprocket 16. One side of the upper sprocket 16 is rotatably connected to the support frame 4 via a rotating frame 17, so that the upper sprocket 16 can rotate on the rotating frame 17, thereby improving the stability of the rotational transmission of the upper sprocket 14.

[0038] Below the upper sprocket 16 is a lower sprocket 18. A chain 30 is meshed between the lower sprocket 18 and the upper sprocket 16. The chain 30 can transmit the power of the upper sprocket 16 to the lower sprocket 18. A sleeve 19 is fixedly installed in the middle of the lower sprocket 18. The surface of the sleeve 19 is rotatably connected to the support frame 4 through the middle bearing 20 to ensure the stability of the rotational transmission of the sleeve 19. A transmission rod 21 is movably inserted inside the sleeve 19, so that the sleeve 19 can drive the transmission rod 21 to rotate while the transmission rod 21 can move inside the sleeve 19.

[0039] An upper gear 35 is fixedly mounted on the surface of the sleeve 19 near the end of the servo motor 6. The lower part of the upper gear 35 is meshed with a lower gear 22, so that the upper gear 35 can drive the lower gear 22 to rotate. A threaded sleeve 23 is fixedly mounted inside the lower gear 22. The threaded sleeve 23 is rotatably connected to the support frame 4 through the lower bearing 29, so that the threaded sleeve 23 can rotate within the lower bearing 29 to ensure the stability of the rotation of the threaded sleeve 23. A lead screw 24 is threadedly connected inside the threaded sleeve 23. The rotation of the threaded sleeve 23 can drive the lead screw 24 to translate. A support arm 25 is rotatably mounted on one end of the transmission rod 21, so that the transmission rod 21 and the support arm 25 can rotate relative to each other. One end of the lead screw 24 is fixedly connected to the support arm 25, so that when the lead screw 24 moves, it can drive the transmission rod 21 to move through the support arm 25.

[0040] A sliding sleeve 26 is fixedly installed at the bottom of the support arm 25. A sliding rod 27 is movably inserted inside the sliding sleeve 26, so that the sliding sleeve 26 can move on the surface of the sliding rod 27 to limit the movement trajectory of the support arm 25. One end of the sliding rod 27 is fixedly connected to the support frame 4, and the other end of the sliding rod 27 is fixedly connected to the support frame 4 through the fixing frame 28 to ensure the stability of the sliding rod 27.

[0041] The operator controls the servo motor 6 to drive the drive shaft 14 to rotate. When the drive shaft 14 rotates, it drives the upper sprocket 16 to rotate. When the upper sprocket 16 rotates, it drives the lower sprocket 18 to rotate through the chain 30. When the lower sprocket 18 rotates, it drives the upper gear 35 to rotate through the sleeve 19. When the upper gear 35 rotates, it drives the thread sleeve 23 to rotate through the lower gear 22. When the thread sleeve 23 rotates, it drives the lead screw 24 to move. When the lead screw 24 moves, it drives the sliding sleeve 26 to move on the surface of the sliding rod 27 through the support arm 25, which increases the stability of the lead screw 24 when it moves.

[0042] At the same time, the support arm 25 will also push the transmission rod 21 to translate along the inside of the sleeve 19, and when the sleeve 19 rotates, it will also drive the transmission rod 21 to rotate, so that the transmission rod 21 can move while rotating.

[0043] In Example 3, based on Example 1, the other end of the lead screw 24 is fixedly mounted with a mounting head 34 via a connector 33, and the other end of the transmission rod 21 is fixedly mounted with a rotating shaft 31. The surface of the rotating shaft 31 is rotatably connected to the connector 33 via a bearing seat 32. The bearing seat 32 can achieve rotational positioning of the rotating shaft 31 to improve the stability of the rotational transmission of the transmission rod 21. A first gear 36 is fixedly mounted on one end of the rotating shaft 31. A second gear 38 is meshed with the lower part of the first gear 36. A connecting ring 37 is fixedly mounted on the middle part of the second gear 38, so that the first gear 36 can drive the connecting ring 37 to rotate through the second gear 38.

[0044] A rotating sleeve 12 is fixedly installed on one side of the connecting ring 37, and the rotating sleeve 12 is rotatably installed on the surface of the mounting head 34, so that the rotating sleeve 12 can rotate on the mounting head 34. One side of the mounting head 34 is fixedly connected to the push plate 9, and the surface of the rotating sleeve 12 is fixedly connected to the rotating ring 10 through four support rods 13. Four vacuum cleaners 11 are fixedly installed inside the rotating ring 10. The vacuum cleaners 11 can suck up the dust. The suction end of the four vacuum cleaners 11 is fixedly connected to the rotating ring 10. The rotating ring 10 has a hollow structure, and several suction ports are opened on the circumferential surface of the rotating ring 10, through which dust can be sucked in.

[0045] When the lead screw 24 moves, it will also drive the push plate 9 and the dust-free brush 8 into the interior of the high-pressure floating zone furnace body 2 through the connector 33 and the mounting head 34, so that the push plate 9 pushes the slag out from the outer door 3 inside the high-pressure floating zone furnace body 2.

[0046] When the transmission rod 21 rotates, it also drives the first gear 36 to rotate via the rotating shaft 31. When the first gear 36 rotates, it drives the connecting ring 37 to rotate via the second gear 38. When the connecting ring 37 rotates, it drives the rotating ring 10 to rotate via the rotating sleeve 12 and the four support rods 13. When the rotating ring 10 rotates, it drives the dust-free brush 8 to rotate, so that the dust-free brush 8 moves inside the high-pressure floating zone furnace body 2 and rotates to clean the slag and ash remaining on its inner wall. The four vacuum cleaners 11 suck up the dust that has been swept up through the suction port on the circumference of the rotating ring 10, thereby improving the cleaning effect.
