[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] A fixing structure of a reactor stirring device comprises a reactor body 1 and a stirring device 6. An insertion hole 2 is provided at the top center of the reactor body 1, a first flange 4 is provided at the top of the insertion hole 2, a second flange 5 is provided at the contact point between the stirring device 6 and the top of the insertion hole 2, the first flange 4 and the second flange 5 are connected by fixing bolts, a base 8 is fixedly connected to the center of the inner bottom of the reactor body 1, a notch is provided at the top center of the base 8, a limiting plate 9 is provided at the bottom of a stirring shaft 7 of the stirring device 6, the limiting plate 9 is located at the notch, a sealing disk 12 is fixedly sleeved on the surface of the stirring shaft 7 of the stirring device 6 and located at the top of the limiting plate 9, sealing cavities 14 are provided at both ends of the connection between the sealing disk 12 and the base 8, a sealing ring 13 is fixedly connected to the sealing cavity 14 at the bottom of the sealing disk 12, and the bottom of the sealing ring 13 is located at the sealing cavity 14 of the base 8.

[0024] Furthermore, a fixed thread 15 is provided on the surface of the stirring shaft 7 of the stirring device 6, and the top of the fixed thread 15 is in the same horizontal plane as the top of the first flange 4. A limit block 16 is fixedly sleeved on the surface of the stirring shaft 7 of the stirring device 6 through the fixed thread 15, and the outer surface of the limit block 16 is in contact with the inner surface of the insertion hole 2.

[0025] Furthermore, a threaded column 10 is provided at the bottom center of the stirring shaft 7 of the stirring device 6 , a threaded hole 11 is provided at the top center of the limiting plate 9 , and the threaded column 10 is threadedly connected to the threaded hole 11 .

[0026] Specifically, it can be seen from the above that both the limit block 16 and the limit plate 9 can be replaced. Considering that the reactor body 1 and the stirring device 6 may be purchased from different manufacturers and the sizes of different manufacturers are also different, the limit plate 9 and the limit block 16 in the utility model can be replaced to meet the size requirements of the notch of the base 8 and the insertion hole 2 respectively. It should be noted that for the replacement of the limit block 16, the limit plate 9 needs to be removed first, and then the limit block 16 is sleeved on the stirring shaft 7 of the stirring device 6, and then the limit block 16 is pushed upward. When it is pushed to the fixing thread 15, the limit block 16 is slowly rotated. When the limit block 16 stops rotating, the limit block 16 is fixed.

[0027] In addition, to fix the limiting plate 9 , it is only necessary to align the threaded hole 11 at the top center of the limiting plate 9 with the threaded column 10 , and then rotate the limiting plate 9 appropriately, so that the limiting plate 9 can be fixed.

[0028] Furthermore, a discharge port 3 is provided at the bottom of the outer surface of the reactor body 1 .

[0029] Furthermore, the rotation direction of the stirring shaft 7 of the stirring device 6 is opposite to the rotation direction of the fixed thread 15 and the threaded column 10. The stirring device 6 makes the rotation direction of the stirring shaft 7 opposite to the rotation direction of the fixed thread 15 and the threaded column 10. When the stirring shaft 7 rotates, the connection between the limit block 16 and the limit plate 9 and the stirring shaft 7 can be tightened.

[0030] It should be noted that the stirring device 6 in the present invention is a prior art, and the specific stirring device 6 that makes the stirring shaft 7 rotate is also a prior art. The specific structure and working principle of the stirring device 6 will not be described in detail here.

[0031] Working principle: The utility model provides a fixing structure for a stirring device of a reactor, and can fix and sleeve limit blocks 16 of different diameters on it through a fixing thread 15, so that the limit plate 9 can be better aligned with the notch through the limit block 16, so that the limit plate 9 can be very simply inserted into the notch on the base 8, thereby further preventing the stirring device 6 from loosening on the reactor and improving the stability of the stirring shaft 7 during rotation.

[0032] In addition, a sealing disk 12 is provided on the surface of the stirring shaft 7 and on the top of the limiting plate 9. The bottom of the sealing disk 12 is sealed with the base 8 by a sealing ring 13, thereby preventing the reactants from entering the notch of the base 8 during the use of the reactor body 1, thereby causing the connection between the limiting plate 9 and the notch to be unstable, causing the stirring device 6 to loosen on the reactor.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
