[0024] The novel indigo synthesis reactor described in the present invention, when working, powdered potassium salt enters the synthesis reactor through the feed port 8, ammonia and sodium are passed through the exothermic reaction, and the heat generated is taken away by the heat-conducting oil in the jacket 2. The outer side of the jacket 2 is provided with an oil inlet 16 and an oil outlet 17. After the powdered potassium salt enters the reactor, the motor 11 drives the stirring shaft 12 to rotate, and the stirring blade 6 adopts a spiral page, which can effectively break up the intermediate material during rotation, thereby increasing the reaction speed of the material and mixing the material evenly; in addition, the bottom of the stirring shaft adopts a special-shaped stirring wing blade 3, which is 30mm away from the lower head of the kettle body and changes according to the shape of the bottom surface of the kettle body.

When the stirring shaft 12 starts to rotate, the potassium salt material on the stirring blade is thrown out along the centrifugal force, and the guide cutting plate also rotates and cuts, forming a local reaction zone between the potassium salt material thrown away and the tangential baffle to obtain an effective reaction. In this way, the cycle continues, the potassium salt material is continuously thrown out, continuously cut, and continuously undergoes local reactions, thereby improving the reaction efficiency.
