[0037] See attached Figure 1-4 The utility model provides a mechanical sealing structure of an artificial graphite coated reactor, comprising the following structure:

[0038] The cover shell 1 has a water outlet guide pipe 11 and a water inlet guide pipe fixedly disposed on the left and right sides of the cover shell 1, respectively.

[0039] A water storage tank 2 is provided with an inner tube 3 penetrating the middle of the water storage tank 2 , a heat exchange tube 4 is wound around the outer side of the inner tube 3 , and a circulation pump 5 is fixedly provided at the right end of the heat exchange tube 4 .

[0040] In this embodiment, Figure 2 and Figure 4 As shown, an upper moving ring 7 is movably connected to the top of the inner wall of the cover shell 1 , a supporting spring 61 is fixedly arranged at the bottom of the upper moving ring 7 , and a lower moving ring 6 is clamped at the bottom of the supporting spring 61 .

[0041] The upper moving ring 7 needs to be assembled on the stirring shaft of the reactor, and the supporting spring 61 completes the assembly of the lower moving ring 6 below the upper moving ring 7 .

[0042] In this embodiment, Figure 2 and Figure 4 As shown, the bottom of the housing 1 is fixedly connected to a stationary ring 8 by bolts, and the bottom of the stationary ring 8 is fixedly connected to a flange 9 by bolts.

[0043] A flange 9 is arranged below the stationary ring 8, and different flanges 9 are used to adapt to various types of reactors in this equipment. This type of design is a conventional technical operation in this technical field.

[0044] In this embodiment, Figure 1 and Figure 2 As shown, an overhead area 21 is fixedly provided at the bottom of the water storage tank 2, and an exhaust port 22 is fixedly provided on the surface of the water storage tank 2 near the overhead area 21 at the bottom.

[0045] The provision of the overhead area 21 and the exhaust port 22 facilitates the air in the middle of the inner tube 3 to be discharged through the overhead area 21 and the exhaust port 22 during the operation of the heat dissipation fan 32 at the top of the inner tube 3 .

[0046] In this embodiment, Figure 1 and Figure 2 As shown, a heat exchange plate 31 is fixedly provided at the middle of the inner tube 3 , a heat dissipation fan 32 is fixedly provided at the top of the inner tube 3 , and an air outlet at the bottom of the inner tube 3 extends to the overhead area 21 .
