[0034] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0035] In conjunction with Figure 1, a reactor for preparing high-boiling-point aromatic solvents of the present invention includes a shell 1, a top plate 5 is provided on the top of the shell 1, a protective ring 6 is fixedly connected to the top of the top plate 5, a motor 12 is fixedly connected to the center position of the top of the top plate 5, a fixing ring 2 is fixedly connected to the bottom of the outer diameter of the shell 1, and evenly distributed support legs 3 are fixedly connected to the bottom of the fixing ring 2. A discharge pipe 22 passes through and is fixedly connected to the bottom of the shell 1, and the outer diameter of the discharge pipe 22 passes through and is provided with a solenoid valve 23. A cover 8 is provided on the top of the protective ring 6, and a feed pipe 7 is provided on the right side of the top of the cover 8, and the feed pipe 7 passes through and extends to one side of the top plate 5.

[0036] When the raw materials are put into the reactor, the feed pipe 7 can be closed. Aromatic hydrocarbon solvents may cause damage to the respiratory system of the workers.

[0037] In conjunction with Figures 2 to 4, the output end of the motor 12 is penetrated and fixedly connected with a rotating rod 13, and the front and rear sides of the outer diameter of the rotating rod 13 are fixedly connected with evenly distributed stirring rods 14. The front and rear sides of the outer ring bottom of the rotating rod 13 are fixedly connected with arc scrapers 21, and the opposite side of the stirring rod 14 is fixedly connected with a scraper 20. The top of the outer diameter of the outer shell 1 is fixedly connected with an annular tube 4, and the inner diameter of the annular tube 4 is penetrated and fixedly connected with evenly distributed branch pipes 19. The right side of the outer diameter of the annular tube 4 is penetrated and fixedly connected with a water inlet pipe 10. The scraper 20 fits tightly against the outer shell 1, and the arc scraper 21 fits tightly against the outer shell 1.

[0038] When the stirring rod 14 and the rotating rod 13 rotate together with the arc-shaped scraper 21 below, the chemical reaction effect can be improved and the precipitation of the raw materials below can be prevented.

[0039] 5 , a heating assembly is provided on the outer ring of the rotating rod 13, and the heating assembly includes a temperature sensor 17, which is fixedly connected to the rotating rod 13. A heating copper tube 11 is provided on the wall thickness of the outer shell 1, and heating heads 18 are fixedly connected at both ends of the heating copper tube 11. A heating wire 9 is passed through and provided on the inner diameter of the rotating rod 13, and a heating wire 9 is passed through and provided on the inner diameter of the stirring rod 14.

[0041] Working principle: When using the reactor, the raw materials can be put into the shell 1 through the feed pipe 7, and then the reactor is heated by the heating wire 9 and the heating copper tube 11. The heating wire 9 first increases the temperature inside the shell 1, and the heating copper tube 11 heats the outer wall of the shell 1, which can increase the heating speed. The temperature is then detected by the temperature sensor 17. When the temperature reaches the standard of chemical reaction, the signal is received by the signal receiver 16, and the control panel 15 can control the heating wire 9 and the heating copper tube 11 to cut off the power, and then stop heating, and then it can be started. The motor 12 drives the rotating rod 13 and the stirring rod 14 to rotate, so that the raw materials are mixed and the reaction speed is accelerated. When use is completed, the inside of the shell 1 needs to be cleaned, and an external water pump can be connected to the water inlet pipe 10, and then water enters the inside of the annular tube 4 and is sprayed out from the branch pipe 19. Then the motor 12 is started to drive the rotating rod 13 to rotate, which can drive the scraper 20 and the curved scraper 21 to rotate. The scraper 20 can clean the inner wall of the shell 1, and then the curved scraper 21 can clean the bottom of the shell 1, and the sewage is discharged from the discharge pipe 22 below.
