[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary skilled persons in the art without creative labor belong to the scope of protection of the utility model.

[0024] Please refer to Figures 1-2 A kind of high-efficiency safe reaction kettle for chemical production, including kettle body 1 and jacket 2, jacket 2 is arranged at the periphery of kettle body 1, and jacket 2 is equipped with liquid inlet pipe 7 and liquid outlet pipe 8, by liquid inlet pipe 7 and liquid outlet pipe 8 external connection liquid supply equipment, so as to continuously pass into the inside of jacket 2 with heating or cooling liquid.

[0025] Further, the space between jacket 2 and kettle body 1 is divided into spiral channel by spiral blade 9 between jacket 2 and kettle body 1, so that the liquid flows along the spiral channel, the liquid inlet pipe 7 is connected at the bottom of the spiral channel, and the liquid outlet pipe 8 is connected at one side of the top of the spiral channel, so that the liquid flows from bottom to top, to ensure the sufficiency of liquid flow in the inside of jacket 2.

[0026] Please refer to Figure 1, in order to ensure that the material in the kettle can be heated or cooled quickly and evenly, the kettle body 1 is provided with a vertical rotating rod 3, the outer wall of the rotating rod 3 is uniformly provided with a plurality of transverse stirring rods 4, the stirring rod 4 and the rotating rod 3 rotate, the temperature distribution of the material in the kettle can be stirred, the stirring rod 4 and the rotating rod 3 are hollow and connected with each other, the upper and lower ends of the rotating rod 3 pass through the top and bottom of the kettle body 1 respectively, and the two ends of the rotating rod 3 pass through the rotary joint 5 and are provided with the connecting pipe 6, the liquid supply equipment is connected through the connecting pipe 6, so that the rotating joint 5 is continuously connected to the rotating rod 3 and the stirring rod 4, the power device is installed on the top of the kettle body 1, and the power device drives the rotating rod 3 to rotate, so that the material in the kettle can be heated or cooled while stirring.

[0027] Specifically, adjacent stirring rods 4 are perpendicular to each other, so that the stirring rods 4 can be uniformly staggered, which can not only improve the stirring effect, but also improve the heating or cooling efficiency.
