Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figures 1-8 As shown, this utility model discloses a chlorination reactor for producing phosphorus trichloride, comprising a support leg 1, a reactor body 2, a reactor lid 3, and a stirring assembly 4, and a protective shell 5. The protective shell 5 is fitted onto the outside of the reactor body 2. Multiple sets of springs 6 and connecting supports 7 are fixedly connected between the reactor body 2 and the protective shell 5. The support leg 1 is mounted on the protective shell 5. The reactor lid 3 is detachably mounted on the reactor body 2. The stirring assembly 4 is mounted on the reactor lid 3. The reactor lid 3 is detachably mounted on the reactor body 2 by a first bolt 24. The reactor lid 3 is provided with a feeding port 19, and a sealing cap 20 is detachably mounted on the feeding port 19. The sealing cap 20 is detachably mounted on the feeding port 19 by a second bolt 25. A discharge pipe 21 is provided at the bottom of the reactor body 2, extending to the outside of the protective shell 5. A solenoid valve 22 is provided on the discharge pipe 21.

[0027] The stirring assembly 4 includes a drive shaft 10, a sleeve shaft 11, a stirring rod 12, and a stirring blade 13. The sleeve shaft 11 is rotatably mounted on the vessel cover 3 and extends downward into the vessel body 2. The stirring rod 12 is mounted on the sleeve shaft 11. The vessel cover 3 is provided with a mounting seat 8. The drive shaft 10 is rotatably mounted on the mounting seat 8 and rotatably passes through the sleeve shaft 11. The stirring blade 13 is mounted on the drive shaft 10. A first bevel gear 14 is sleeved on the drive shaft 10. A second bevel gear 15 is sleeved on the sleeve shaft 11. A third bevel gear 9 is rotatably mounted on the mounting seat 8. Both the first bevel gear 14 and the second bevel gear 15 mesh with the third bevel gear 9. A motor 23 is provided on the mounting seat 8. One end of the drive shaft 10 is located on the output shaft of the motor 23.

[0028] It also includes a gas purifier 17, with an exhaust pipe 16 connected to the gas inlet of the gas purifier 17. The exhaust pipe 16 is located on the lid 3 and communicates with the interior of the vessel body 2.

[0029] The stirring rod 12 is equipped with a scraper 18, which contacts the inner wall of the vessel body 2.

[0030] In practical use, the raw materials are added into the vessel body 2 through the feeding port 19, then the sealing cover 20 is closed, and the motor 23 is started. The motor 23 drives the drive shaft 10 to rotate, which in turn drives the first bevel gear 14 to rotate. The first bevel gear 14 drives the third bevel gear 9 to rotate, which in turn drives the second bevel gear 15 to rotate. The second bevel gear 15 drives the sleeve shaft 11 to rotate, and the rotation direction of the sleeve shaft 11 is opposite to that of the drive shaft 10. The drive shaft 10 and the sleeve shaft 11 drive the stirring blade 13 and the stirring rod 12 to rotate in opposite directions, thereby mixing the raw materials more evenly and improving the reaction efficiency. During the rotation of the stirring rod 12, the scraper 18 will also rotate, and the scraper 18 can clean the impurities remaining on the inner wall of the vessel body 2.

[0031] During the reaction, the gas produced is discharged through exhaust pipe 16 and enters gas purifier 17 for purification. After the reaction is completed, the solenoid valve 22 is opened, and the material can be discharged through discharge pipe 21.

[0032] By setting a protective shell 5 on the outside of the vessel body 2, and setting a spring 6 and a connecting support 7 between the vessel body 2 and the protective shell 5, the anti-collision effect of the vessel body 2 can be effectively enhanced, the risk of material leakage inside the vessel body 2 can be reduced, and the safety of the vessel body 2 in use can be improved.

[0033] In summary, this design includes a protective shell 5 on the outside of the vessel body 2, and a spring 6 and a connecting support 7 between the vessel body 2 and the protective shell 5. This effectively enhances the anti-collision effect of the vessel body 2, reduces the risk of leakage of substances inside the vessel body 2, and improves the safety of the vessel body 2. This design also includes a stirring assembly 4, which can perform bidirectional three-dimensional stirring of the substances inside the vessel body 2, improving the stirring effect. Furthermore, this design includes a gas purifier 17, which can purify the exhaust gas to avoid harm to the environment and personnel. Finally, this design includes a scraper 18, which can clean the inner wall of the vessel body 2, reducing the residue of impurities inside the vessel body 2.
