In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

Referring to fig. 1 and 2, according to an embodiment of the present invention, a sealing assembly 100 is provided, which includes a mounting base 10, a cover 20 and a sealing member 30. The mounting seat 10 has a first end and a second end opposite to each other, the first end is used for being mounted to the outer wall of an external reaction device, and the second end is provided with a conical groove 11. The mounting seat 10 is further opened with a wire passage 12 communicating with the tapered groove 11 and extending to the first end of the mounting seat 10. The tapered recess 11 and the line passage 12 are aligned with and communicate with an opening provided in the outer wall of the reaction apparatus for the passage of cables and the like into the interior of the apparatus. The seal 30 comprises a lower conical portion 32, which is conical in shape, inserted into the conical recess 11, the surface of which abuts and abuts against the wall surface of the conical recess 11. The cover 20 covers the sealing member 30 and is connected to the second end of the mounting seat 10. The cover 20 has a wire passing opening 21, and the sealing element 30 has a wire passing hole 34 communicating the wire passing channel 12 of the mounting seat 10 and the wire passing opening 21 of the cover 20, so that cables and the like can pass through the wire passing hole and enter the inside of the device.

In use, taking temperature measurement as an example, eight temperature measurement points are required inside the reaction apparatus, and sixteen independent wire through holes 34 (shown in fig. 2) are correspondingly provided on the sealing member 30. Eight pairs (sixteen) of thermocouple wires are firstly respectively passed through sixteen wire passing holes 34 of the sealing member 30, and then the lower cone portion 32 of the sealing member 30 is inserted into the tapered groove 11 of the mounting seat 10, so that one end of the thermocouple wires is passed through the wire passing passage 12 of the mounting seat 10 and the opening of the outer wall of the device to extend to the outside of the device, and the other end of the thermocouple wires is passed through the wire passing opening 21 of the cover body 20 to extend to the inside of the device. Finally, the cap 20 is fixed to the second end of the mounting seat 10, in the process, the cap 20 presses the sealing member 30 downward, so that the gap between the cap 20 and the sealing member 30 is eliminated, and the outer surface of the lower tapered portion 32 of the sealing member 30 is fitted and abutted against the wall surface of the tapered groove 11, thereby eliminating the gap between the sealing member 30 and the mounting seat 10. When the cover 20 presses the sealing member 30 downward, the sealing member 30 is offset toward the wire passage 12 with respect to the tapered groove 11, so that the lower tapered portion 32 of the sealing member 30 is pressed radially by the wall surface of the tapered groove 11, and thus the thermocouple wires passing through the wire passage holes 34 are pressed by the lower tapered portion 32 of the sealing member 30 to eliminate a gap with the lower tapered portion 32. Thereby, the tightness of the seal assembly is ensured. In addition, the thermocouple wires extending to the inside of the device can form eight pairs of thermocouples, and the thermocouple wires can be bent, so that the thermocouple wires can be arranged at a desired measuring point in a manner of adapting to a complicated structure inside the device, and the requirement of multi-point measurement is met. The thermocouple wires are listed herein only for illustrating the beneficial effects of the sealing assembly 100 of the present embodiment, and do not limit the sealing assembly 100 of the present embodiment. For example, in addition to the thermocouple wires described above, the sealing assembly 100 of the present embodiment may be passed through by other cables or metal rods, and the like, which can also achieve the above-mentioned effects.

In some embodiments, it may be designed that the taper angle of the tapered recess 11 of the mount 10 is slightly less than the taper angle of the lower taper 23 of the seal 30. Thus, when the lower taper portion 23 is inserted into the taper groove 11, the amount of radial compression of the lower taper portion 23 by the taper groove 11 is increased, further ensuring the sealing effect.

In some embodiments, the cover 20 includes a bottom wall opposite the mount 10, and a first inner peripheral wall connecting the bottom wall and enclosing a conical space 22. The seal 30 also includes an upper tapered portion 31 that is tapered. When the lid body 20 is placed on the seal 30, the upper tapered portion 31 of the seal 30 is accommodated in the tapered space 22, and the surface of the upper tapered portion 31 is fitted and pressed against the bottom wall and the first inner peripheral wall of the lid body 20. In use, the cover body 20 presses the sealing element 30, so that the upper conical part 31 of the sealing element 30 is radially pressed by the first inner peripheral wall of the cover body 20, and therefore, cables and the like passing through the wire passing holes 34 are pressed by the upper conical part 31 of the sealing element 30, a gap between the cables and the upper conical part 31 is eliminated, and the sealing performance of the sealing assembly is further ensured.

In some embodiments, the cover 20 further includes a second inner peripheral wall connecting the first inner peripheral wall and extending away from the bottom wall to enclose the cylindrical space 23. An internal thread is arranged on the second inner peripheral wall, and an external thread matched with the internal thread is arranged on the outer peripheral wall of the second end of the mounting seat 10. Thereby, the cover 20 can be easily attached to the mount 10. Further, in some embodiments, the seal 30 also includes a cylindrical middle post portion 33 interposed between the upper and lower cone portions 31, 32. The center pillar portion 33 of the seal 30 is accommodated in the cylindrical space 23, and a gap is formed between the surface of the center pillar portion 33 and the second inner peripheral wall. When the cover 20 is screwed to the mounting seat, the sealing element 30 cannot rotate along with the cover 20 due to the gap between the outer peripheral wall of the middle column part 33 and the second inner peripheral wall, and the cables penetrating through the sealing element 30 cannot be wound and pulled along with the rotation, so that the cables are prevented from being damaged.

In some embodiments, the seal 30 is made of viton. Preferably, the hardness of the fluororubber may be shore 70A to shore 80A. The use of the fluororubber of this hardness enables the sealing member 30 to seal the cable or the like passing through the wire through hole 34 after being pressed.

In some embodiments, the seal assembly 100 further includes a cable 40 that extends through the wire passage 12 of the mount 10, the wire hole 34 of the seal 30, and the wire passage opening 21 of the cover 20 in that order. The cable 40 includes a signal wire 41 and a protective sheath 42 covering the signal wire 41. In some embodiments, the durometer of the protective sleeve 42 is less than the durometer of the seal 30. When the protective sleeve 42 is radially compressed by the sealing member 30, the protective sleeve 42 is deformed accordingly and eliminates a gap with the signal line 41, further ensuring the sealing performance of the sealing assembly. In some embodiments, the protective sheath 42 is made of polytetrafluoroethylene. It is noted that when used in high temperature equipment, the protective sleeve 42 may not be able to withstand the high temperatures inside the equipment, and therefore the protective sleeve 42 is designed to extend only a small amount (e.g., 100 mm) out of the sealing block toward the inside of the equipment. In some embodiments, signal wire 41 is a thermocouple wire, which may be, for example, 0.5 millimeters in diameter. When the signal line 41 is a thermocouple wire, accordingly, the number of the line passing holes 34 may be set to be even. Optionally, in other embodiments, the sealing assembly 100 further includes a metal rod (not shown in the drawings) passing through the wire passing hole 34 of the sealing member 30, and two ends of the metal rod are respectively used for connecting cables disposed inside and outside the device. In some embodiments, the metal rod is a copper rod, which may have a diameter of, for example, 5 millimeters.
