[0022] Reference Figures 1 to 4The utility model embodiment is a cephalosporin acylation reactor, which includes a tank body 1: a pair of support blocks 2 are fixedly connected to the bottom of the tank body 1, and a sealing cover 3 is sleeved on the top of the tank body 1, an internal thread is provided on the inner wall of the sealing cover 3, and an external thread matching the internal thread is provided on the outer wall of the tank body 1, a vertical pipe 4 passes through the sealing cover 3, a limiting ring 5 is fixedly connected to the vertical pipe 4, and a plurality of stirring blocks 6 and a flushing pipe 7 are fixedly connected to the vertical pipe 4, and the flushing pipe 7 is communicated with the inner cavity of the vertical pipe 4, and the top of the sealing cover 3 is provided with a plurality of stirring blocks 6 and a flushing pipe 7. The upper part is fixedly connected with a shell body 8, and the top of the sealing cover 3 is fixedly connected with a motor 9, the output shaft of the motor 9 passes through the shell body 8 and is fixedly connected with a transmission gear 10, the vertical pipe 4 is fixedly connected with a ring gear 11, the ring gear 11 is meshed with the transmission gear 10, the sealing cover 3 is fixedly connected with a feeding pipe 12, the bottom of the tank body 1 is fixedly connected with a discharge pipe 13, a valve is installed on the discharge pipe 13, a pair of spoiler blocks 14 are fixedly connected to the inner wall of the tank body 1, and a protective mechanism is provided outside the tank body 1.

[0023] The force is evenly distributed, which improves the stability of the tank body 1 in use. A pair of support blocks 2 are symmetrically arranged about the central axis of the tank body 1.

[0024] To facilitate unscrewing the sealing cover 3 , a pair of handles 15 are fixedly connected to the sealing cover 3 .

[0025] It can buffer the impact force, thereby protecting the tank body 1. The protection mechanism includes an annular plate 16, which is fixedly connected to the tank body 1, and a protection ring 17 is provided on the annular plate 16. The protection ring 17 is sleeved on the tank body 1, and a plurality of springs 18 are fixedly connected between the protection ring 17 and the outer wall of the tank body 1.

[0026] In order to improve the comprehensiveness of stirring of the reaction liquid, a plurality of stirring blocks 6 are evenly distributed on the vertical tube 4 .

[0027] In order to improve the comprehensiveness of the cleaning of the inner wall of the tank body 1 , a plurality of flushing pipes 7 are evenly distributed on the vertical pipe 4 .

[0028] The force is evenly distributed, and the pair of handles 15 are symmetrically arranged about the central axis of the sealing cover 3.

[0029] Working principle: When the utility model is used, the reagent is added through the feeding tube 12, and then the motor 9 is started, the motor 9 drives the transmission gear 10 to rotate, the transmission gear 10 drives the ring gear 11 and the vertical tube 4 to rotate, and the vertical tube 4 drives the stirring block 6 to rotate, so as to stir the reaction liquid. During the stirring process of the reaction liquid, the reaction liquid is cut and mixed by the spoiler block 14. When the reaction liquid needs to be discharged, the valve on the discharge pipe 13 is opened to discharge the reaction liquid. When the inner wall of the tank body 1 needs to be cleaned, the motor 9 is started, and the motor 9 drives the transmission gear 10 and the ring gear 11 to rotate. The vertical pipe 4 is driven to rotate, and the vertical pipe 4 drives the flushing pipe 7 to rotate, and then water is introduced into the vertical pipe 4, so that the inner wall of the tank body 1 is flushed through the vertical pipe 4 and the flushing pipe 7 to flush the inner wall of the tank body 1. When the inner wall of the tank body 1 needs to be further cleaned, the motor 9 is turned off, and the sealing cover 3 is unscrewed by holding the handle 15, and then the sealing cover 3 is removed upwards. At this time, the inner wall of the tank body 1 can be further cleaned to improve the cleanliness of the tank body 1. When the tank body 1 is impacted, the impact force pushes the protective ring 17 to move, and the protective ring 17 squeezes the spring 18, so that the impact force is absorbed by the spring 18 to protect the tank body 1.
