Description

Technical Field

[0002] The thermal insulation mechanical seal of a reactor is one of the key sealing components used in reactors in industries such as chemical and pharmaceutical. Its main function is to reduce or prevent heat transfer through the shaft seal while ensuring that the material inside the reactor does not leak, thereby protecting the mechanical seal from the effects of high or low temperatures and extending its service life.

[0003] The dynamic and static rings of the thermally insulated mechanical seal of the reactor generate heat during high-speed rotation and friction. If this heat cannot be dissipated in time, it will cause the temperature of the sealing surface to rise, thereby causing aging, wear or even failure of the sealing material. Cooling components can help maintain the working temperature of the mechanical seal within a reasonable range, thus maintaining the smoothness and integrity of the sealing surface and ensuring sealing performance. Traditional cooling devices are often stationary, resulting in cooling dead zones and the cooling effect needs to be improved.

[0027] The present invention relates to a heat-insulating mechanical seal device for a reactor, comprising a mechanical seal body 1, and further comprising: a first cooling component 2, which is disposed at the bottom of the mechanical seal body 1, the first cooling component 2 comprising a lower mounting plate 21 and a plurality of mounting screws 22 for fixing the lower mounting plate 21 to the mounting flange of the mechanical seal body 1; the lower mounting plate 21 is fixedly connected to an upper mounting plate 24 via a plurality of connecting plates 23; a first rotating plate 27 is rotatably connected to the top of the lower mounting plate 21; a second rotating plate 29 is rotatably connected to the bottom of the upper mounting plate 24; a plurality of fixed fans 28 are fixedly connected between the first rotating plate 27 and the second rotating plate 29; the first cooling component 2 is used to cool the stationary ring at the bottom of the mechanical seal body 1; and a second cooling component 3, which is disposed at the top of the mechanical seal body 1, comprising a top plate 31 fixedly connected above the second rotating plate 29 and a plurality of track plates 32 disposed above the top plate 31; a moving fan 37 is slidably disposed on the track plates 32; the second rotating plate 29 is used to cool the moving ring at the top of the mechanical seal body 1.

[0028] In other words, the first cooling component 2 can cool the stationary ring of the mechanical seal, while the second cooling component 3 can cool the rotating ring of the mechanical seal. In addition, the fan 37 can adjust its distance from the rotating ring, so that the device can be adapted to mechanical seals of more sizes and models, and the cooling effect can be adjusted by adjusting its position according to specific working conditions.

[0029] Secondly, a first motor 25 is fixedly connected to the lower mounting plate 21, and a first gear 26 is fixedly connected to the output end of the first motor 25. The first rotating plate 27 is provided with multiple teeth that mesh with the first gear 26. The first motor 25 is used to drive the first rotating plate 27 to rotate when starting. In other words, the first rotating plate 27 and multiple fixed fans 28 can rotate simultaneously to ensure that each position at the bottom of the mechanical seal body 1 can receive a uniform cooling effect.

[0030] In addition, a first rotating block 210 with a "T"-shaped cross section is fixedly connected to the bottom of the first rotating plate 27, and a first rotating groove 211 adapted to the size of the first rotating block 210 is provided on the lower mounting plate 21.

The third rotating plate 34 has multiple teeth, and the third rotating plate 34 meshes with multiple second gears 33. It should be noted that the third rotating plate 34 can be rotatably connected to the top plate 31 by installing a rotating ring or other device, that is, the third rotating plate 34 can rotate relative to the top plate 31.

[0032] Furthermore, a second motor 35 is fixedly connected to the top plate 31, and a third gear 351 is fixedly connected to the output end of the second motor 35.

[0033] It should be noted that the power supply for the fixed fan 28 can be located inside the first rotating plate 27, and the power supply for the moving fan 37 can be located inside the top plate 31. In specific settings, the first motor 25 can adopt a forward and reverse alternating working mode. In addition, the moving fan 37 can also be adjusted by driving the third rotating plate 34 through the second motor 35 as the top plate 31 rotates. That is to say, the position of the moving fan 37 can be adjusted according to the specific working conditions while the cooling device is running continuously, which improves the practicality of the device.
