[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1, referring to Figure 1 and Figure 4-5 A graphite tube reactor includes a counterweight base 1 and a vertical plate 2 welded to the top outer wall of the counterweight base 1. An angle adjustment seat 3 is hinged to the upper part of the vertical plate 2. The graphite tube reactor body 4 is installed on the angle adjustment seat 3. A control panel 17 is fixedly installed on the side wall of the vertical plate 2. The control panel 17 can control the electrical components of the entire reactor. A solenoid valve 18 is installed at the lower part of the graphite tube reactor body 4. A feed hopper 19 is fixedly connected to the top of the graphite tube reactor body 4.

[0026] Specifically, the graphite tube reactor body 4 is equipped with a temperature-controlled stirring mechanism, which includes a T-shaped motor base 6 welded to the top outer wall of the graphite tube reactor body 4, a temperature sensor fixedly installed on the top outer wall of the graphite tube reactor body 4, a cooling stirring assembly and a heating stirring assembly, and the detection end of the temperature sensor extends into the graphite tube reactor body 4.

[0027] Furthermore, the refrigeration stirring assembly includes a first heat-insulating shaft 7 rotatably mounted on the top of the graphite tube reactor body 4, a refrigeration rod 8 coaxially fixedly connected to the bottom outer wall of the first heat-insulating shaft 7, a first spiral stirring blade 9 welded to the outer wall of the refrigeration rod 8, and a first drive motor 10 fixedly mounted on one side of the outer wall of the T-shaped motor base 6.

[0028] Furthermore, the heating stirring assembly includes a second heat-insulating shaft 11 rotatably mounted on the top of the graphite tube reactor body 4, an electric heating rod 12 coaxially fixedly connected to the bottom outer wall of the second heat-insulating shaft 11, a second spiral stirring blade 13 welded to the outer wall of the electric heating rod 12, and a second drive motor 14 fixedly mounted on one side of the outer wall of the T-shaped motor base 6.

[0029] Furthermore, the output shaft of the first drive motor 10 is coaxially and fixedly connected to the top end of the first heat insulation shaft 7 through the first coupling, and the output shaft of the second drive motor 14 is coaxially and fixedly connected to the top end of the second heat insulation shaft 11 through the second coupling. The spiral directions of the first spiral stirring blade 9 and the second spiral stirring blade 13 are opposite, and both the first spiral stirring blade 9 and the second spiral stirring blade 13 are located inside the graphite tubular reactor body 4.

[0030] In addition, the first heat insulation shaft 7 is made of a metal material that can insulate against low temperatures, and the second heat insulation shaft 11 is made of a metal material that can insulate against high temperatures. The purpose is to prevent the low temperature of the cooling rod 8 and the high temperature of the electric heating rod 12 from being transferred outward and affecting the normal operation of the first drive motor 10 and the second drive motor 14. At the same time, in order to ensure the normal operation of the cooling rod 8 and the electric heating rod 12 in the rotating state, electric slip rings can be installed on the upper part of the first heat insulation shaft 7 and the second heat insulation shaft 11.

[0031] The working principle of this embodiment is as follows: First, the solution to be reacted is added into the graphite tube reactor body 4 through the feed hopper 19. Then, the reaction temperature inside the graphite tube reactor body 4 is controlled by a temperature-controlled stirring mechanism. Second, when the temperature sensor detects that the temperature inside the graphite tube reactor body 4 is high, a cooling signal is transmitted to the control panel 17. The control panel 17 then controls the operation of the cooling stirring component, that is, the first drive motor 10 operates the first spiral stirring blade 9 on the first heat insulation shaft 7 to rotate and condense the solution to be reacted to achieve the purpose of cooling. When the temperature sensor detects that the temperature inside the graphite tube reactor body 4 is low, a heating signal is transmitted to the control panel 17. The control panel 17 then controls the operation of the heating stirring component, that is, the second drive motor 14 operates the second spiral stirring blade 13 on the second heat insulation shaft 11 to rotate and heat the solution to be reacted to achieve the purpose of heating. In this way, the reaction temperature inside the graphite tube reactor can be intelligently controlled, which is beneficial to improving the reaction efficiency of the graphite tube reactor. Finally, after the reaction is completed, the discharge is performed by opening the solenoid valve 18.

[0032] Example 2, refer to Figure 1-3 This embodiment is an optimization based on embodiment 1. Specifically, two hydraulic cylinders 5 are symmetrically hinged between the vertical plate 2 and the angle adjustment seat 3. Four threaded pins 15 are welded on the outer wall of the graphite tubular reactor body 4. The angle adjustment seat 3 has four corresponding insertion holes. The four threaded pins 15 are respectively inserted into the four insertion holes. One end of each of the four threaded pins 15 is threaded with a butterfly locking nut 16. The four butterfly locking nuts 16 are all fastened to the side wall of the angle adjustment seat 3.

[0033] The working principle of this embodiment is as follows: First, during use, the two hydraulic cylinders 5 are operated synchronously through the control panel 17 to flexibly adjust the tilt angle of the graphite tube reactor body 4; Second, the four threaded pins 15 on the graphite tube reactor body 4 are inserted into the corresponding four holes and locked with four butterfly locking nuts 16 to achieve the effect of fixed installation, and the graphite tube reactor body 4 can be disassembled and maintained by unscrewing the four butterfly locking nuts 16.
