[0048] Reference Figures 1 to 6 The following is a further description of an embodiment of the adhesive heat preservation cylinder of this utility model.

[0049] A type of heat-insulating cylinder includes a cylinder body 1. It should be noted that in use, the cylinder body 1 is inserted into a single-crystal furnace, and a support plate 2 is fixedly mounted on the cylinder body 1. Multiple support plates 2 are provided and evenly distributed on the cylinder body 1. Multiple evenly distributed heat-insulating grooves 3 are formed inside the cylinder body 1. Multiple evenly distributed internal grooves 4 are also formed on the cylinder body 1. A connecting groove 5 is formed on the surface of the internal groove 4 near the heat-insulating groove 3. An annular retaining groove 6 is formed on the surface of the cylinder body 1 near the support plate 2. The device also includes:

[0050] An adjusting member is disposed on the support plate 2, the adjusting member comprising:

[0051] The adjusting motor 15 is fixedly mounted on the support plate 2. It should be noted that the adjusting motor 15 is electrically connected to an external control device.

[0052] An adjusting shaft 16 is rotatably mounted on the support plate 2, and one end of the adjusting shaft 16 near the adjusting motor 15 is fixedly connected to the output end of the adjusting motor 15.

[0053] The drive gear 17 is fixedly mounted on the end of the adjustment shaft 16 away from the adjustment motor 15.

[0054] A transmission mechanism is disposed on the cylinder 1, and the transmission mechanism includes:

[0055] An annular locking block 18 is rotatably disposed within the annular locking groove 6;

[0056] Driven gear 19 is fixedly disposed at one end of the annular locking block 18 away from the cylinder 1, and driven gear 19 meshes with driving gear 17;

[0057] The tooth 20 has multiple teeth, and the multiple teeth 20 are evenly distributed circumferentially on the surface of the driven gear 19 near the cylinder 1.

[0058] A rotating component, located within the built-in groove 4, comprises:

[0059] An internal shaft 21 is located in the internal groove 4, and one end of the internal shaft 21 is rotatably connected to the cylinder 1. A double-ended screw 22 is fixedly provided at the other end of the internal shaft 21, and the threads at both ends of the double-ended screw 22 are opposite in direction.

[0060] The transmission gear 23 is fixedly mounted on the built-in shaft 21, and the transmission gear 23 meshes with the teeth 20;

[0061] There are two threaded blocks 24, and the two threaded blocks 24 are slidably disposed in the built-in groove 4. The threaded blocks 24 are threadedly connected to the double-ended screw 22, and the two threaded blocks 24 are respectively fixedly connected to the adjacent connecting blocks 11.

[0062] During operation, staff can adjust the performance of the insulation cylinder according to actual production needs. The specific process is as follows: the adjustment motor 15 is started by external control equipment, which causes the adjustment shaft 16, which is fixedly connected to the output end of the adjustment motor 15, to rotate. This, in turn, drives the drive gear 17, which is fixedly connected to the adjustment shaft 16, to rotate. Through the meshing between the drive gear 17 and the driven gear 19, the driven gear 19 rotates. Through the meshing between the teeth 20 on the driven gear 19 and the transmission gear 23, the transmission gear 23 rotates. This causes the built-in shaft 21, which is fixedly connected to the transmission gear 23, to rotate. This causes the double-ended screw 22, which is fixedly connected to the built-in shaft 21, to rotate. Through the threaded transmission between the double-ended screw 22 and the two threaded blocks 24, the two threaded blocks 24 move away from or closer to each other.

[0063] A temperature regulating mechanism is disposed within the insulation tank 3. The temperature regulating mechanism is used to adjust the insulation performance of the cylinder 1. The temperature regulating mechanism includes:

[0064] The first insulation board 7 is slidably disposed in the insulation groove 3, and two symmetrically arranged adaptation grooves 8 are provided on the first insulation board 7, and an adaptive component is disposed in the adaptation groove 8.

[0065] The second insulation board 9 is slidably disposed in the insulation groove 3. Two symmetrically arranged adaptation grooves 8 are also provided on the second insulation board 9, and an adaptive component is also provided in the adaptation groove 8 of the second insulation board 9. The space between the first insulation board 7 and the second insulation board 9 is the insulation space 10.

[0066] There are two connecting blocks 11, and the two connecting blocks 11 are symmetrically distributed in the connecting groove 5. The connecting blocks 11 are slidably connected to the connecting groove 5, and the two connecting blocks 11 are respectively fixedly connected to the adjacent first insulation board 7 and second insulation board 9.

[0067] When the two threaded blocks 24 move away from or move closer to each other, the two connecting blocks 11 fixedly connected to the two threaded blocks 24 move away from or move closer to each other, which in turn causes the first insulation plate 7 and the second insulation plate 9 fixedly connected to the two connecting blocks 11 to move away from or move closer to each other. This adjusts the volume of the insulation space 10 between the first insulation plate 7 and the second insulation plate 9, thereby adjusting the insulation performance of the insulation cylinder. By providing a temperature adjustment mechanism, this device can adjust the volume of the insulation space 10 between the first insulation plate 7 and the second insulation plate 9, thus adapting the insulation performance of this device to different production insulation needs, thereby improving the applicability of this device to a certain extent.

[0068] The adaptive component includes:

[0069] There are multiple adaptive springs 12, and the multiple adaptive springs 12 are equidistantly arranged in the adaptive groove 8, and the adaptive springs 12 are always in a compressed state;

[0070] Two first adapting plates 13 are provided, and the two first adapting plates 13 are slidably disposed in the adapting groove 8 of the first insulation plate 7. The first adapting plates 13 are fixedly connected to the adapting springs 12 in the first insulation plate 7.

[0071] There are two second adaptation plates 14, and the two second adaptation plates 14 are slidably disposed in the adaptation groove 8 of the second insulation plate 9. The second adaptation plates 14 are fixedly connected to the adaptation spring 12 in the second insulation plate 9.

[0072] When the first insulation plate 7 and the second insulation plate 9 are far apart or close together in the insulation groove 3, the adaptive component allows the first adaptive plate 13 and the second adaptive plate 14 to slide into or out of the adaptive groove 8 under the action of the adaptive spring 12. This ensures that the first adaptive plate 13 and the second adaptive plate 14 are always in contact with the surface of the insulation groove 3, thereby ensuring the insulation performance of the insulation space 10 and thus ensuring the insulation stability of the insulation cylinder after adjusting the insulation performance.

[0073] It should be noted that the materials of the first insulation board 7, the second insulation board 9, the first adapting board 13, and the second adapting board 14 are all insulation materials, such as high-purity graphite. Using high-purity graphite as the material for the first insulation board 7, the second insulation board 9, the first adapting board 13, and the second adapting board 14 can effectively ensure the insulation performance of the insulation cylinder.

[0074] Working Principle: During operation, the operator can adjust the performance of the insulation cylinder according to actual production needs. The specific process is as follows: An external control device starts the regulating motor 15, causing the regulating shaft 16, which is fixedly connected to the output end of the regulating motor 15, to rotate. This, in turn, drives the drive gear 17, which is fixedly connected to the regulating shaft 16, to rotate. Through the meshing between the drive gear 17 and the driven gear 19, the driven gear 19 rotates. Through the meshing between the teeth 20 on the driven gear 19 and the transmission gear 23, the transmission gear 23 rotates, thereby causing the inner... The rotation of the shaft 21 drives the double-headed screw 22, which is fixedly connected to the internal shaft 21, to rotate. Through the threaded transmission between the double-headed screw 22 and the two threaded blocks 24, the two threaded blocks 24 move away from each other or move closer to each other. This causes the two connecting blocks 11, which are fixedly connected to the two threaded blocks 24 respectively, to move away from each other or move closer to each other. This causes the first insulation plate 7 and the second insulation plate 9, which are fixedly connected to the two connecting blocks 11 respectively, to move away from each other or move closer to each other. This adjusts the volume of the insulation space 10 between the first insulation plate 7 and the second insulation plate 9, thereby adjusting the insulation performance of the insulation cylinder.

[0075] When the first insulation plate 7 and the second insulation plate 9 are far apart or close together in the insulation groove 3, the adaptive component allows the first adaptive plate 13 and the second adaptive plate 14 to slide into or out of the adaptive groove 8 under the action of the adaptive spring 12. This ensures that the first adaptive plate 13 and the second adaptive plate 14 are always in contact with the surface of the insulation groove 3, thereby ensuring the insulation performance of the insulation space 10 and thus ensuring the insulation stability of the insulation cylinder after adjusting the insulation performance.

[0076] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
