At present, the phthalic anhydride method is mainly used to prepare saccharin in China. This method has a simple process and high yield, but the automatic control technology is relatively backward, especially the diazotization reaction. The reaction conditions are harsh and the yield is low. Improving the level of automation in this field has always been the unremitting goal pursued by people in the industry. Diazotized compounds are generally prepared by intermittent diazotization reactions.

[0026] See also Figures 1 to 3 The utility model provides a new technical solution: an automatic control continuous production device for diazo compounds, comprising two fixed blocks 1, the two fixed blocks 1 are arranged in a front-to-back manner, the lower sides of the two fixed blocks 1 are fixedly connected to support legs 2, a reactor body 3 is rotatably connected between the two fixed blocks 1, the front side of the reactor body 3 has no blocking cover, the rear side of the reactor body 3 is fixedly connected to a blocking cover, the outer surface of the reactor body 3 is provided with an opening groove 4, the opening groove 4 is communicated with the interior of the reactor body 3, a switch door 5 is provided on the opening groove 4, the switch door 5 and the opening A rotating shaft 6 is rotatably connected between the grooves 4, and the switch door 5 and the open groove 4 are rotatably connected through the rotating shaft 6. The switch door 5 and the rotating shaft 6 can be snapped together. The switch door 5 is an existing structure, so no further explanation is given. A handle 7 is fixedly connected to the upper side of the switch door 5. A stirring mechanism is provided inside the front fixing block 1 and the reactor body 3. The stirring mechanism can evenly stir the material inside the reactor body 3. The stirring mechanism includes a motor assembly 8, a stirring shaft 10, three stirring blades 11, a rotating ring groove 12, a first gear 13 and a second gear 14.

[0027] Furthermore, the motor assembly 8 is fixedly connected to the front side of the fixed block 1, and the output end of the motor assembly 8 is fixedly connected to the transmission shaft 9. The rear end of the transmission shaft 9 rotates and passes through the front fixed block 1. The rear end of the transmission shaft 9 rotates and extends into the interior of the reactor body 3. The stirring shaft 10 is fixedly connected to the rear end of the transmission shaft 9. The rotating annular groove 12 is opened on the rear wall of the reactor body 3. The rear end of the stirring shaft 10 is slidingly connected to the rear wall of the rotating annular groove 12. The three stirring blades 11 are all fixedly connected to the outer surface of the stirring shaft 10. The three stirring blades 11 are arranged in a ring array on the outer surface of the stirring shaft 10. The three stirring blades 11 are all arranged in the interior of the reactor body 3. The first gear 13 is fixedly sleeved on the outer surface of the stirring shaft 10. The first gear 13 is arranged on the rear side of the stirring blade 11. The second gear 14 is fixedly connected to the rear wall of the reactor body 3, and the second gear 14 is meshed with the first gear 13.

[0028] Furthermore, when the reaction is carried out, the switch door 5 is opened after the card is released, and then various materials are poured into the interior of the reactor body 3, and then the switch door 5 is closed and carded, and then the motor assembly 8 is started. The motor assembly 8 starts to transmit power from the output end, driving the transmission shaft 9 to start rotating, and the transmission shaft 9 drives the stirring shaft 10 to rotate, and the stirring shaft 10 drives the stirring blade 11 to start rotating. When the stirring blade 11 rotates, it will stir the material inside the reactor body 3.

The motor assembly 8 starts to transmit power from the output end, driving the transmission shaft 9 to start rotating, the transmission shaft 9 drives the stirring shaft 10 to rotate, and the stirring shaft 10 drives the stirring blade 11 to start rotating. When the stirring blade 11 rotates, it will stir the materials inside the reactor body 3, and at the same time, the stirring shaft 10 will drive the first gear 13 to rotate synchronously, and the first gear 13 will drive the meshing second gear 14 to rotate synchronously. The first gear 13 and the second gear 14 are meshed and connected to each other, so the rotation direction of the stirring shaft 10 is opposite to that of the reactor body 3, which further improves the mixing efficiency. After the reaction is completed, it is only necessary to rotate the switch door 5 to the bottom side to discharge it from the opening slot 4.
