[0002] As a common fine chemical production equipment, ultra-low temperature reactors are widely used. The transmission shaft in the reactor usually runs through the inside and outside of the equipment and is set on the reactor. Therefore, there is a circumferential gap between the transmission shaft and the reactor equipment. Especially when the reactor is working, the material medium in the reactor equipment leaks out through the gap, causing unnecessary waste or industrial accidents.

[0003] In order to avoid leakage, a rubber ring is often set on the drive shaft for sealing. However, due to the low internal temperature of the ultra-low temperature reactor during use, the rubber ring often shrinks when it is cold through heat transfer, affecting the sealing effect, which has certain shortcomings.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Embodiment 1:

[0028] Reference Figure 1-6 The sealing assembly includes a sealing rubber ring 2, and also includes: a cavity 201, which is arranged on the inner ring of the sealing rubber ring 2; a connecting pipe 203, which is annularly installed in the sealing rubber ring 2, and the connecting pipe 203 is communicated with the cavity 201, and is used to inject gas into the cavity 201 to expand the cavity 201; an air inlet pipe 205, which is installed on the sealing rubber ring 2, and the air inlet pipe 205 is communicated with the connecting pipe 203; an air outlet pipe 206, which is installed on the sealing rubber ring 2, and the air outlet pipe 206 is communicated with the connecting pipe 203, and the air inlet pipe 205 and the air outlet pipe 206 are arranged opposite to each other, and a plurality of groups of small holes 202 are arranged on the sealing rubber ring 2, and the small holes 202 are used to discharge the gas in the cavity 201, A convex ring 204 is fixedly connected to the sealing rubber ring 2. The ultra-low temperature reactor includes a sealing component, including a reactor body 1. The reactor body 1 is connected to a reactor cover 101, and the reactor cover 101 is connected to a motor 102. The output end of the motor 102 passes through the reactor cover 101. The sealing rubber ring 2 is used to seal the output end of the motor 102. The output end of the motor 102 is connected to a coupling 103. A mounting hole 104 is provided on the reactor cover 101. A mounting flange 3 is installed on the reactor cover 101 through the mounting hole 104. The mounting flange 3 is used to fix the sealing rubber ring 2. An empty hole 301 is provided on the mounting flange 3. The empty hole 301 is used for the extension of the air inlet pipe 205 and the air outlet pipe 206.

[0029] When the device is in use, it is necessary to configure an industrial hot air pump, connect the outlet head of the industrial hot air pump to the air inlet pipe 205, and install an electronic valve and a pressure valve in the air outlet pipe 206. When in use, by starting the industrial hot air pump, the gas can gradually enter the connecting pipe 203 and finally enter the cavity 201. At this time, the gas entering will gradually fill the cavity 201, and part of the gas will be discharged through the small hole 202, and then contact the rotating shaft of the motor 102. These gases will blow some rubber residues remaining on the rotating shaft. Due to the setting of the convex ring 204, the convex ring 204 will be against the rotating shaft, and the debris will float upward. The amount of gas entering is greater than the amount of gas discharged. At the same time, the electronic valve is closed. At this time, the cavity 201 will gradually increase and expand until the inner ring of the sealing rubber ring 2 is against the rotating shaft. At this time, the small hole 202 will not be able to discharge the gas, and the sealing of the rotating shaft is completed. The electronic valve on the outlet pipe 206 can be opened to continuously discharge excess gas, and the pressure is detected by the pressure valve to keep the pressure moderately within a suitable range.

[0030] Subsequently, the reactor body 1 can be started to react the materials inside the reactor. During the process, the gas blown out by the industrial hot air pump will continuously heat the sealing rubber ring 2 to keep it at a certain temperature, thereby avoiding shrinkage caused by too low a temperature and affecting the sealing effect.

[0031] The gas can be replaced by hot oil, but in this case, the small hole 202 needs to be removed to avoid leakage of the hot oil.

[0032] Embodiment 2:

[0033] Reference Figure 1-6 The sealing assembly and the ultra-low temperature reactor are basically the same as those in Example 1, and furthermore: a plurality of friction lines 207 are arranged at the bottom of the sealing rubber ring 2.

[0034] By providing the friction pattern 207 , the stability of the sealing rubber ring 2 can be improved during use, and rotation can be avoided to cause bending of the air inlet pipe 205 and the air outlet pipe 206 , thereby facilitating stable entry and discharge of gas.

[0035] The utility model is provided with a sealing rubber ring 2 with a cavity 201. When in use, warm gas can be continuously injected into the sealing rubber ring 2 to keep the sealing rubber ring 2 at a certain temperature, reduce the shrinkage of the sealing rubber ring 2, and facilitate the use of the ultra-low temperature reactor.

[0036] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
