[0022] See also Figure 1 On the one hand, the embodiment of the present application provides a crucible rib 14, including a rib bottom 2 and a rib wall 1. The rib bottom 2 includes a first surface, and the rib wall 1 includes a second surface, the first surface abuts against the second surface, so that the rib bottom 2 and the rib wall 1 form a crucible rib 14, the first surface is provided with a first protrusion 4, along the first direction, a second protrusion 5 is provided on one side of the first protrusion 4, the first direction is perpendicular to the normal direction of the first surface, the second surface is provided with a first recessed portion 3, the first protrusion 4 and the first recessed portion 3 are clearance-matched, along the first direction, the first recessed portion 3 includes a third surface, the third surface is provided with a second recessed portion 6, and the second recessed portion 6 is used to accommodate the second protrusion 5.

[0023] The first surface may be the top wall surface of the side bottom 2 , and the second surface may be the bottom wall surface of the side wall 1 . When the first surface and the second surface are in contact with each other, the side bottom 2 and the side wall 1 enclose a space for accommodating the crucible 15 .

[0024] The first direction may be the direction shown by the X-axis in the figure, and the first direction may also be perpendicular to the axial direction of the wall 1 .

[0025] The first protrusion 4 cooperates with the first recess 3 to position the side wall 1 when the side wall 1 is installed. The second protrusion 5 cooperates with the second recess 6 to lock the side wall 1 so that the side wall 1 cannot be separated from the side bottom 2. Specifically, when the first protrusion 4 is inserted into the first recess 3, the side wall 1 is rotated so that the second protrusion 5 is inserted into the second recess 6. At this time, the first protrusion 4 cannot move out of the first recess 3 along the normal direction of the first surface.

[0026] By setting the side wall 1 and the side bottom 2 as a split structure, when one of the side wall 1 or the side bottom 2 is damaged, the side wall 1 and the side bottom 2 can be separated and the damaged component can be replaced, thereby reducing the use cost of the thermal device.

[0027] The side wall 1 can be fixed to the side bottom 2 by rotating the side wall 1, and the fixing is convenient and quick.

[0028] A high temperature resistant sealing gasket may be provided between the first surface and the second surface, which can, on the one hand, increase the sealing effect between the first surface and the second surface, and on the other hand, when the side bottom 2 and the side wall 1 are in contact, the sealing gasket is compressed and can generate an elastic restoring force, thereby reducing the risk of the second protrusion 5 escaping from the second recessed portion 6.

[0029] In some embodiments, around the circumference of the side wall 1 , the side bottom 2 is provided with a plurality of first protrusions 4 , and the side wall 1 is provided with a plurality of first recesses 3 .

[0030] Correspondingly, the second protruding portion 5 and the second recessed portion 6 are also provided in plurality.

[0031] The plurality of first protrusions 4 and the plurality of first recesses 3 are connected correspondingly, thereby increasing the connection strength between the side bottom 2 and the side wall 1 .

[0032] In some embodiments, along the first direction, the sum of the length of the first recessed portion 3 plus the length of the second recessed portion 6 is greater than or equal to the sum of the length of the first recessed portion 3 plus the length of the second recessed portion 6 .

[0033] The advantage of such an arrangement is that the first protruding portion 4 and the second protruding portion 5 can smoothly enter the first recessed portion 3 , thereby enabling the second protruding portion 5 to cooperate with the second recessed portion 6 .

[0034] See also Figure 2 On the other hand, the embodiment of the present application further provides a thermal field device, including a heat preservation chamber 7, a crucible side 14 and a crucible 15 in the above embodiment. The crucible side 14 is accommodated in the heat preservation chamber 7, and the crucible 15 is accommodated in the crucible side 14.

[0035] The heat preservation chamber 7 has a heat preservation effect, so that the crucible 15 therein can be in a high temperature environment.

[0036] The crucible side 14 is used to support the crucible 15 .

[0037] In some embodiments, a heating component 11 is further included, and the heating component 11 is used to heat the crucible 15 .

[0038] The heating component 11 can be selected from existing products, and its structure and working principle are well known to those skilled in the art, and will not be described in detail here. For example, the heating component 11 can be an electric heating device.

[0039] In some embodiments, the heating component 11 is disposed around the circumference of the crucible side 14 .

[0040] The heating component 11 is disposed around the circumference of the crucible side 14, so that the crucible 15 is heated more evenly, thereby improving the heating effect on the material.

[0041] In some embodiments, a guide channel 16 is further included. The guide channel 16 is disposed in the heat preservation chamber 7 and is used to add materials into the crucible 15 .

[0042] The material can be introduced into the crucible 15 through the guide channel 16, thereby reducing the risk of the material being scattered around when added.

[0043] The guide channel 16 can be detachably connected to the heat preservation chamber 7 . By removing the guide channel 16 , the opening of the heat preservation chamber 7 can be fully opened, so that the crucible 15 can be easily disassembled and assembled.

[0044] In some embodiments, the guide channel 16 is in a frustum shape, and the small diameter side of the guide channel 16 is close to the opening of the crucible 15 .

[0045] The large diameter side of the guide channel 16 is used for adding materials, and the small diameter side of the guide channel 16 is used for discharging materials.

[0046] The frustum-shaped guide channel 16 facilitates the addition of materials, and on the other hand allows the guide channel 16 to extend into the crucible 15, thereby reducing the risk of material scattering.

[0047] Furthermore, the guide channel 16 may also be in a prism shape, with the small end of the guide channel 16 close to the opening of the crucible 15 .

[0048] In some embodiments, the heat preservation chamber 7 is provided with a placement portion 12, the placement portion 12 is provided with a third recessed portion 13, and the peripheral wall of the third recessed portion 13 is an arc surface.

[0049] The third recessed portion 13 of the placement portion 12 is used to place the crucible side 14 , so that the crucible side 14 can be fixed in the heat preservation chamber 7 .

[0050] The peripheral wall of the third recessed portion 13 is an arc surface, which, on the one hand, enables the third recessed portion 13 to play a centering function, that is, when the crucible rib 14 is accommodated in the third recessed portion 13, the posture of the crucible rib 14 can be adjusted. On the other hand, the adaptability of the crucible rib 14 is increased, that is, the third recessed portion 13 can accommodate crucible ribs 14 of different sizes.

[0051] In some embodiments, the peripheral wall of the insulation cavity 7 includes a first cavity wall segment 8, a second cavity wall segment 9 and a third cavity wall segment 10 connected in sequence, the first cavity wall segment 8 is close to the bottom wall of the insulation cavity 7, and the diameters of the first cavity wall segment 8, the second cavity wall segment 9 and the third cavity wall segment 10 gradually decrease.

[0052] The advantage of such an arrangement is that, on the one hand, the external dimensions of the heat preservation chamber 7 can be more compact, reducing the space occupied by the thermal field device. On the other hand, the materials required for manufacturing the heat preservation chamber 7 are saved, thereby reducing the cost. On the other hand, a boss structure can be formed between two adjacent cavity wall sections, and the boss structure can be used to position the structure installed in the heat preservation chamber 7. For example, the heat preservation chamber 7 can be provided with a cover body 17 for closing the opening of the heat preservation chamber 7, and a boss structure can be formed between the second cavity wall section 9 and the third cavity wall section 10, and the boss structure can position the cover body 17 when the cover body 17 is covered on the opening of the heat preservation chamber 7.
