[0026] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0027] It should be noted here that if Figure 4 As shown, the draft tube includes an outer draft tube 21 and an inner draft tube 22. Insulation felt is installed between the inner wall of the outer draft tube 21 and the outer wall of the inner draft tube 22 to ensure thermal insulation between the inner and outer draft tubes 22, prevent temperature loss in the inner draft tube 22, and ensure temperature stability and uniformity within the furnace. However, when the insulation felt is filled, it is prone to incomplete compaction, resulting in large gaps within the felt, which reduces the thermal insulation performance of the draft tube.

[0028] In order to solve the above technical problems, the guide tube insulation felt assembly component provided by the utility model is used to assemble the insulation felt inside the guide tube, which can effectively improve the compaction effect of the insulation felt on the inner wall of the outer guide tube 21, and ensure the insulation effect of the insulation felt on the guide tube, so as to avoid the problem of reduced thermal insulation performance of the guide tube.

[0029] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the guide tube insulation felt assembly assembly includes a first pressing member 11 for inserting into the outer guide tube 21, a first guide rod 12 connected to the first end of the first pressing member 11, and a first adjusting member 13 movably connected to the first guide rod 12. The first pressing member 11 extends along a predetermined direction, wherein the predetermined direction is the length direction of the guide tube (i.e. Figure 4 The first adjusting member 13 is adapted to move toward the first pressing member 11 along the length direction of the first guide rod 12 so that the first pressing member 11 compacts the thermal insulation felt onto the outer guide tube 21.

[0030] According to the guide tube insulation felt assembly assembly provided in this embodiment, after the insulation felt is installed into the outer guide tube 21 and the insulation felt needs to be compacted against the inner wall surface of the outer guide tube 21, the second end of the first pressing member 11 is inserted into the side of the insulation felt away from the outer guide tube 21 along the length direction of the guide tube, and the first guide rod 12 is abutted against the opening of the outer guide tube 21, and then the first adjusting member 13 is driven to make the first adjusting member 13 and the first pressing member 11 move toward each other along the length direction of the first guide rod 12, so as to utilize the first pressing member 11 to compact the insulation felt against the inner wall surface of the outer guide tube 21, thereby ensuring the compaction effect of the insulation felt on the inner wall surface of the outer guide tube 21, effectively improving the insulation effect of the insulation felt on the guide tube, and avoiding the problem of reduced thermal insulation performance of the guide tube.

[0031] Furthermore, because the first guide rod 12 abuts against the opening of the outer guide tube 21 and is connected to the first end of the first pressing member 11, the first end of the first pressing member 11 protrudes outside the opening of the outer guide tube 21. Consequently, when the first pressing member 11 is used to compact the insulation felt, it is only necessary to drive the first adjusting member 13 and the first pressing member 11 toward each other outside the opening of the outer guide tube 21. This effectively reduces the difficulty of assembling the insulation felt and improves the efficiency of installing the various components of the guide tube.

[0032] Furthermore, the inner guide tube 22 is generally installed inside the insulation felt after the insulation felt is assembled. However, due to the friction between the insulation felt and the outer wall of the inner guide tube 22, the assembly quality and assembly efficiency of the inner guide tube 22 are easily affected. In order to ensure the assembly quality and assembly efficiency of the inner guide tube 22, as shown in FIG. Figure 1 and Figure 2 As shown, the guide tube insulation felt assembly assembly also includes a first adapter 14, which is arranged in the middle of the first clamping member 11, and the first adapter 14 forms a first arc surface 141 on the side facing the first guide rod 12. The curved shape of the first arc surface 141 is adapted to the outer wall shape of the inner guide tube 22, so as to utilize the first arc surface 141 of the first adapter 14 to increase the contact area between the first clamping member 11 and the insulation felt, thereby further improving the compaction effect of the insulation felt on the inner wall surface of the outer guide tube 21.

[0033] At the same time, because the first curved surface 141 of the first adapter 14 is adapted to the outer wall of the inner flow guide tube 22, when the first pressing member 11 drives the first adapter 14 to compact the insulation felt, the first adapter 14 can press the inner wall of the insulation felt into a curved surface that adapts to the outer wall of the inner flow guide tube 22, thereby forming an installation space inside the insulation felt for the inner flow guide tube 22. The inner flow guide tube 22 can then be inserted into the installation space inside the insulation felt to complete the assembly of the inner flow guide tube 22. The adaptable curved surface can reduce friction between the inner flow guide tube 22 and the insulation felt, thereby improving the assembly efficiency and quality of the inner flow guide tube 22 inside the insulation felt.

[0034] Preferably, in order to ensure that the curved shape of the first arc surface 141 is adapted to the shape of the outer wall surface of the inner guide tube 22, the arc surface radius of the first adapter 14 is equal to the outer wall radius of the inner guide tube 22, so as to ensure that the inner wall surface of the thermal insulation felt after compaction is equal to the radius of the inner guide tube 22, thereby ensuring that when the inner guide tube 22 is installed inside the thermal insulation felt, the inner wall surface of the thermal insulation felt can abut against the outer wall surface of the inner guide tube 22, thereby ensuring the thermal insulation effect of the thermal insulation felt on the inner guide tube 22.

[0035] Furthermore, a clearance fit is formed between the outer wall of the inner guide tube 22 and the inner wall of the insulation felt, further improving the assembly efficiency of the inner guide tube 22 when the inner guide tube 22 is installed inside the insulation felt. The insulation felt itself has a certain degree of resilience. When the inner guide tube 22 is installed, the insulation felt expands within a certain space and then abuts against the outer wall of the inner guide tube 22, thereby achieving the insulation effect of the insulation felt on the inner guide tube 22.

[0036] In this embodiment, in order to facilitate the rapid installation and disassembly between the first adapter 14 and the first clamping member 11, the first adapter 14 and the first clamping member 11 are detachably connected, so that the first adapter 14 with different curvature specifications can be replaced according to the inner diameter of the outer guide tube 21, further ensuring the insulation effect of the insulation felt on the inner guide tube 22.

[0037] Specifically, the first clamping member 11 is formed with a plug-in hole. After the first adapter 14 is inserted into the plug-in hole, the self-locking screw is screwed into the first clamping member 11 and the first adapter 14 from the side of the first clamping member 11 away from the first guide rod 12 to fix the first adapter 14 to the first clamping member 11, thereby threading the first adapter 14 to the first clamping member 11.

[0038] In the process of compacting the thermal insulation felt, the first adjusting member 13 and the first pressing member 11 need to cooperate to compact the thermal insulation felt. In order to facilitate the operation of the first adjusting member 13 and the first pressing member 11, as shown in FIG. Figure 1 and Figure 2 As shown, the first guide rod 12 is a threaded guide rod, the first adjusting member 13 is formed with an internal thread, and the first adjusting member 13 is threadedly connected to the threaded guide rod.

[0039] It can be understood that by rotating the first adjusting member 13 in the direction of the first pressing member 11, the first adjusting member 13 and the first pressing member 11 can be moved toward each other to make the first adjusting member 13 abut against the outer wall surface of the outer guide tube 21; then continue to rotate the first adjusting member 13 in the direction of the first pressing member 11, so that the first pressing member 11 moves toward the first adjusting member 13, and ensure that the first adjusting member 13 is abutted against the outer wall surface of the outer guide tube 21, thereby utilizing the cooperation of the first adjusting member 13 and the first pressing member 11 to achieve the compaction operation of the thermal insulation felt.

[0040] Since it is only necessary to operate the first adjusting member 13 outside the outer guide tube 21 during the entire process of compacting the thermal insulation felt, the compacting operation of the guide tube thermal insulation felt assembly on the thermal insulation felt is simplified.

[0041] It should be noted here that the compacting operation of the insulation felt by the guide tube insulation felt assembly component is not limited to the above-mentioned operation method. The first guide rod 12 can also be a straight rod, and the first adjusting member 13 is slidably arranged on the first guide rod 12. When the first pressing member 11 is required to compact the insulation felt, the first adjusting member 13 can be pushed toward the outer wall of the outer guide tube 21, and the first adjusting member 13 can be manually pressed against the outer wall of the outer guide tube 21, and then the first guide rod 12 is pulled to drive the first pressing member 11 to compact the insulation felt.

[0042] Among them, the first clamping member 11 and the first adapter member 14 are both made of rigid materials to ensure that the first clamping member 11 and the first adapter member 14 will not produce excessive deformation under a force of a certain intensity, thereby ensuring that the first clamping member 11 and the first adapter member 14 can compress the thermal insulation felt, and ensure that the shape of the thermal insulation felt after being compressed can match the inner guide tube 22, while avoiding damage to the first clamping member 11 and the first clamping plate.

[0043] For example, the first pressing member 11 and the first adapter member 14 are both plate-shaped structures made of stainless steel. Of course, both can also be made of other rigid materials, which can be selected according to actual conditions.

[0044] In another embodiment of the present invention, Figure 2 As shown, the guide tube insulation felt assembly also includes a second pressing member 15. The first end of the second pressing member 15 is connected to the first guide rod 12. The second pressing member 15 is located between the first adjusting member 13 and the first pressing member 11. The area of ​​the second pressing member 15 facing the first pressing member 11 is larger than the area of ​​the first adjusting member 13 facing the first pressing member 11. Furthermore, the second pressing member 15 can be used to increase the contact area between the first adjusting member 13 and the outer wall of the outer guide tube 21, thereby dispersing the pressing pressure of the first adjusting member 13 on the outer wall of the outer guide tube 21 and reducing local stress concentration. This prevents deformation and damage to the outer guide tube 21 caused by excessive pressure applied by the first adjusting member 13 when the first pressing member 11 compacts the insulation felt. The second pressing member 15 is preferably made of the same material as the first pressing member 11 and is formed into a plate-like structure.

[0045] Preferably, the shape of the first pressing member 11 is adapted to the shape of the inner wall of the outer guide tube 21, and the shape of the second pressing member 15 is adapted to the outer wall of the outer guide tube 21, so as to ensure the compaction effect of the thermal insulation felt by the coordinated movement between the first pressing member 11 and the second pressing member 15.

[0046] Furthermore, a buffer layer is provided on the side of the second pressing member 15 facing the first pressing member 11. When the second pressing member 15 presses the outer wall of the outer guide tube 21, the buffer layer reduces the impact force of the second pressing member on the outer wall of the outer guide tube 21, further preventing the outer guide tube 21 from deforming due to impact when it contacts the second pressing member 15. The buffer layer also reduces the impact vibration generated when the second pressing member 15 contacts the outer guide tube 21, thereby reducing the propagation of impact noise.

[0047] Preferably, the buffer layer is preferably a buffer pad such as a rubber pad or a silicone pad, so as to utilize the elasticity and shock resistance of the buffer pad to ensure absorption and dispersion of impact force and ensure the service life of the buffer pad.

[0048] Furthermore, the outer guide tube 21 and the inner guide tube 22 are usually provided with two openings to guide the melt flow and control heat conduction. The uniform arrangement of the insulation felt inside the outer guide tube 21 and the inner guide tube 22 can improve the stability of the temperature field inside the guide tube, thereby ensuring the growth quality and efficiency of the single crystal. In order to ensure that the insulation felt assembly of the guide tube can evenly compact the insulation felt at the two openings of the outer guide tube 21, such as Figure 3 As shown, the draft tube insulation blanket assembly further includes a second guide rod 17 and a second adjustment member 18. The second guide rod 17 is connected to the second end of the first pressing member 11. The distance between the first guide rod 12 and the second guide rod 17 is equal to the length of the outer draft tube 21. The second adjustment member 18 is rotatably connected to the second guide rod 17 and is adapted to move toward the second pressing member 15.

[0049] It is understood that when the insulation felt assembly of the guide tube compacts the insulation felt against the inner wall of the outer guide tube 21, the first adjusting member 13 and the second adjusting member 18 can be rotated simultaneously with the same torque. The first adjusting member 13 cooperates with the first pressing member 11 to ensure the insulation felt is compacted at one of the openings in the outer guide tube 21. Simultaneously, the second adjusting member 18 cooperates with the first pressing member 11 to ensure the insulation felt is compacted at the other opening in the outer guide tube 21. Furthermore, under the action of the same torque, the insulation felt at the two openings is subjected to equal compaction force, thereby ensuring uniform compaction of the insulation felt at the two openings and preventing the insulation felt at the other opening from being compacted less effectively than the insulation felt at one opening.

[0050] It should be noted here that the second guide rod 17 and the first guide rod 12 use rods with the same structural parameters, and the structures of the first adjusting member 13 and the second adjusting member 18 are also the same to ensure that the tensioning forces acting on the first clamping member 11 by the first adjusting member 13 and the second adjusting member 18 are equal.

[0051] Among them, such as Figure 3As shown, the length of the second pressing member 15 is equal to that of the first pressing member 11, and the extension direction of the second pressing member 15 is the same as that of the first pressing member 11. The second end of the second pressing member 15 is connected to the second guide rod 17. Furthermore, when the first pressing member 11 is pulled to compact the thermal insulation felt, the first adjusting member 13 and the second adjusting member 18 can simultaneously press against the outer wall surface of the outer guide tube 21 through the second pressing member 15, thereby enabling the second pressing member 15 to simultaneously increase the contact area between the first adjusting member 13 and the outer guide tube 21, as well as the contact area between the second adjusting member 18 and the outer guide tube 21, and further enhance the compaction effect of the first pressing member 11 on the thermal insulation felt, thereby improving the compaction efficiency of the thermal insulation felt.

[0052] Furthermore, multiple second adapters 19 are spaced apart on the side of the second compression member 15 facing away from the second adjustment member 18. A second curved surface is formed on the side of the second adapter 19 facing the first compression member 11. The curved shape of the second curved surface matches the outer wall shape of the outer guide tube 21. The multiple second adapters 19 increase the contact area between the second compression member 15 and the outer guide tube 21, further dispersing the pressing pressure of the first adjustment member 13 and the second adjustment member 18 on the outer wall of the outer guide tube 21 to prevent damage to the outer guide tube 21. At the same time, the cooperation between the second adapters 19 and the first adapter 14 enhances the pressing force of the second compression member 15 and the first compression member 11 on the insulation felt, thereby further enhancing the compaction effect on the insulation felt.

[0053] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
