[0027] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] See also Figures 1 to 8 As shown, this utility model provides a preparation device, which includes: a base 10; a container 20 mounted on the base 10, the container 20 having a reaction chamber, and at least one first hanging part 30 provided on the container 20; a stirring assembly 40 including a base 41 and a stirring part 42, the stirring part 42 being rotatably mounted on the base 41, and the stirring part 42 being made of a non-metallic material; a driving structure 50 drivingly connected to the stirring part 42 to drive the stirring part 42 to rotate relative to the base 41; and a lifting mechanism 60 including a lifting device 62, the lifting device 62 including at least one second hanging part 621, the first hanging part 30 and the second hanging part 621 forming a hanging cooperation.

[0029] In this embodiment, the drive structure 50 is driven to connect with the stirring part 42 to drive the stirring part 42 to rotate relative to the base 41. The stirring part 42 is used to stir the reactants in the reaction chamber. The first hanging part 30 and the second hanging part 621 can form a hanging engagement, thereby enabling the container 20 to be lifted from the base 10 and moved to other positions via the lifting mechanism 60. One of the first hanging part 30 and the second hanging part 621 is a lifting ring, and the other is a hook. Through the engagement of the first hanging part 30 and the second hanging part 621, the container 20 can be lifted and lowered before and after heating, avoiding direct handling of the container 20 under high temperature conditions and reducing the risk to operators. The stirring part 42 is made of non-metallic material, which has high chemical stability in high temperature and high oxygen environments and is not prone to reacting with oxygen to generate oxides. Compared with metallic materials, the stirring part 42 made of non-metallic material will not produce impurities such as metal oxides at high temperatures, avoiding contamination of the reactants and thus ensuring the purity and performance of the product.

[0030] In one embodiment, both the stirring part 42 and the container 20 are made of quartz, which makes the stirring part 42 have high chemical stability in high temperature and high oxygen environment and not easily react with oxygen to generate oxides. At the same time, it also makes the container 20 not only resistant to high temperature but also transparent, making it easy to observe the state of the material in the reaction chamber of the container 20.

[0031] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the stirring assembly 40 further includes a transmission part 43, which is mounted on the base 41 and is in transmission cooperation with the stirring part 42. The driving structure 50 is mounted on the base 10 and is drivingly connected to the transmission part 43.

[0032] With the above configuration, the stirring unit 42 can be rotated, thereby achieving a stirring effect. Furthermore, the rotational speed of the stirring unit 42 can be adjusted by changing the transmission ratio, thus achieving precise control of the stirring speed.

[0033] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the transmission part 43 includes a first mounting base 431, a first bearing 432, a transmission shaft 433, and a synchronous belt 434. The first bearing 432 is mounted on the first mounting base 431. The first end of the transmission shaft 433 is mounted inside the first bearing 432 and is connected to the stirring part 42. The second end of the transmission shaft 433 is fixedly sleeved with a first synchronous pulley 435. The drive structure 50 includes a drive motor 51 and a second synchronous pulley 52. ​​The second synchronous pulley 52 is disposed at the output end of the drive motor 51. The synchronous belt 434 is wound around the first synchronous pulley 435 and the second synchronous pulley 52.

[0034] In this embodiment, when the drive motor 51 starts, its output end begins to rotate, driving the second synchronous pulley 52 mounted thereon to rotate. As the second synchronous pulley 52 rotates, the synchronous belt 434, which is wound around the first synchronous pulley 435 and the second synchronous pulley 52, begins to run, driving the first synchronous pulley 435 to rotate. The rotation of the first synchronous pulley 435 is transmitted to the stirring unit 42 through the transmission shaft 433, thereby achieving stirring of the materials in the reaction chamber. This configuration not only reduces energy loss but also improves the stability and accuracy of the transmission.

[0035] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the transmission part 43 further includes a coupling 436 and a second bearing 47. The second bearing 47 is mounted on the base 41, and the stirring part 42 passes through the second bearing 47 so that the stirring part 42 can rotate relative to the base 41. The first end of the transmission shaft 433 is connected to the stirring part 42 through the coupling 436.

[0036] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the drive structure 50 further includes a connecting plate 53, an adjusting block 54, at least one first connecting member 55, an adjusting bolt 56, and two second connecting members 57.

The connecting plate 53 and the adjusting block 54 are both fixedly mounted at the mounting position 16. The connecting plate 53 is provided with at least one elongated hole 531, which extends along a first direction. The at least one elongated hole 531 and the at least one first connecting member 57 are connected to the drive motor 51. The connecting parts 55 are set one-to-one. The first connecting part 55 passes through the elongated hole 531 in sequence and is fixedly connected to the base 10. The adjusting block 54 is fixedly connected to the base 10 through two second connecting parts 57. One end of the adjusting bolt 56 passes through the adjusting block 54 and rotates with the adjusting block 54. The other end of the adjusting bolt 56 is threadedly connected to the end of the connecting plate 53 away from the hoisting mechanism 60. By rotating the adjusting bolt 56, the distance between the adjusting block 54 and the connecting plate 53 can be adjusted, thereby realizing the adjustment of the tension of the synchronous belt 434.

[0037] See also Figures 1 to 8As shown, in one embodiment of the present invention, the hoisting mechanism 60 further includes a second mounting base 61, which is rotatably mounted on the base 10. The second mounting base 61 includes a first mounting body 611 and a second mounting body 612 connected to each other. A connecting seat 11 is provided on the base 10. The first mounting body 611 is rotatably connected to the connecting seat 11. Along the first direction, the second mounting body 612 has a first end and a second end that are arranged opposite to each other. Both the first end and the second end of the second mounting body 612 are provided with fixed pulleys 70. The hoisting mechanism 60 further includes a power unit 63 and a hoisting rope 64. The power unit 63 is mounted on the first mounting body 611. The first end of the hoisting rope 64 is connected to the power unit 63. The power unit 63 is used to release and retract the hoisting rope 64. The hoisting rope 64 is wound around two fixed pulleys 70 in sequence. The second end of the hoisting rope 64 is connected to the lifting device 62.

[0038] In this embodiment, the second mounting base 61 is composed of a first mounting section 611 and a second mounting section 612 connected together. Through the cooperation of a fixed pulley 70 and a lifting rope 64, the lifting operation of the container 20 becomes more flexible and precise. The first mounting section 611 is rotatably connected to the connecting seat 11 on the base 10, allowing the second mounting base 61 to rotate in multiple directions, providing a wider range of lifting angles. The power unit 63 is mounted on the first mounting section 611. By controlling the release and retraction of the lifting rope 64, the lifting device 62 can move vertically, which improves the applicability of the preparation device, reduces manual intervention, lowers labor intensity, and enhances safety.

[0039] In one embodiment, the power unit 63 adopts a small household hoist from the prior art, the specific structure of which will not be described in detail here.

[0040] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the second end of the suspension rope 64 is provided with a hook 641, the mounting frame 622 is provided with a connecting ring 624 and a connecting rope 623, one end of the connecting rope 623 is connected to the mounting frame 622, the second end of the connecting rope 623 is connected to the second hanging part 621, and the second end of the suspension rope 64 is hung in the connecting ring 624 through the hook 641.

[0041] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the lifting device 62 further includes a mounting frame 622, which is connected to the second end of the lifting rope 64, and the second hanging part 621 is mounted on the mounting frame 622.

[0042] In this embodiment, the installation frame 622 increases the load-bearing capacity of the lifting device 62, enabling the lifting mechanism 60 to stably support and move the heavier container 20, thus ensuring the stability of the container 20 during the lifting process.

[0043] See also Figures 1 to 8 As shown, in one embodiment of the present invention, there are at least two second hanging parts 621 and at least two first hanging parts 30. The mounting frame 622 has a first end and a second end that are arranged opposite to each other. At least one second hanging part 621 is provided at both the first end and the second end of the mounting frame 622. At least one first hanging part 30 is provided on both the first side and the second side of the container 20. At least two first hanging parts 30 and at least two second hanging parts 621 are arranged in a one-to-one correspondence.

[0044] Through the above settings, on the one hand, multi-point support can be achieved for the container 20 during the hoisting process. This not only improves the stability of the container 20 during the hoisting process, but also enables more precise control of the position of the container 20, preventing the container 20 from tilting or shifting during hoisting. On the other hand, the one-to-one correspondence between at least two first hanging parts 30 and at least two second hanging parts 621 ensures that the weight of the container 20 can be evenly distributed during hoisting, reducing the risk of deformation or damage to the container 20 due to excessive force at a single point.

The base 10 includes a frame 12 and a support structure 13 provided on the frame 12. The overlapping structure 80 overlaps with the support structure 13.

[0046] In this embodiment, the cooperation between the overlapping structure 80 and the support structure 13 enables the container 20 to be stably positioned on the support structure 13 of the base 10 during the heating process. In addition, compared with the support method that directly contacts the inner wall or bottom of the container 20, the overlapping structure 80 at the top of the container 20 can reduce the pressure on the vulnerable parts of the container 20, avoid the risk of damage or breakage caused by uneven stress on the container 20, and extend the service life of the container 20.

[0047] See also Figures 1 to 8 As shown, in one embodiment of the present invention, the overlapping structure 80 includes at least two overlapping parts 81. Along the first direction, the container 20 has a first side and a second side arranged opposite to each other.

The support structure 13 includes at least two support parts 131, and the at least two support parts 131 are arranged in a one-to-one correspondence with the at least two overlapping parts 81.

[0048] The above settings enhance the stability of container 20 and ensure multi-point contact during placement to evenly distribute the weight of container 20 and avoid tilting or instability that may result from single-point force.

[0049] In one embodiment, the support body 131 is provided with a groove, and the overlapping body 81 is adapted to the groove so that the overlapping body 81 can be inserted into the groove.

[0051] In this embodiment, the through hole provided on the connecting structure 90 allows the stirring part 42 to pass through and enter the reaction chamber to stir the materials inside the reaction chamber, dissipating the heat inside the materials and preventing the materials from sintering due to excessively high temperatures inside the reaction chamber. The connecting structure 90 enables the connection between the container 20 and the stirring part 42.
