Problems solved by technology

[0003] During the use of the traditional stirred tank reactor, under the action of centrifugal force, when the stirring blade rotates, the material around the stirring shaft will be continuously thrown to the inner wall of the reactor, and the liquid above and below the stirring blade will flow to the vicinity of the stirring shaft. However, for some high-viscosity liquids, after the stirring blades throw out the material around the stirring shaft, due to the high viscosity of the material, the flow rate of the material is very slow, and the material cannot be replenished around the stirring shaft in time. A cavity is generated, which will cause the material to accumulate on the inner wall of the reactor, and the material at the inner wall of the reactor is almost stagnant, and the material cannot be fully mixed, resulting in the reaction not being able to proceed smoothly
Moreover, for some high-viscosity liquids, when a large amount of material accumulates on the stirring blade, it is easy to overload the motor and cause the motor to burn out

Embodiment 2

[0034] In Example 2, refer to figure 2 , the electromagnetic generator is sleeved on the end of the outer side wall of the tubular casing 1 , at this time, the electromagnetic generator only includes the electromagnetic coil 4 , and the rest is the same as that of the first embodiment. Compared with Embodiment 1, the electromagnetic generator is arranged on the outer wall of the tubular casing 1, so that the size of the first heat exchange mechanism 10 on the outer wall of the tubular casing 1 will be correspondingly reduced, and the heat exchange efficiency may be slightly lower. in Example 1. The reactors of Examples 1 and 2 can be used for high viscosity, high pressure, and strongly exothermic or strongly endothermic reactions.

Embodiment 3

[0035] In Example 3, refer to image 3, compared with Embodiment 2, the return mechanism is an elastic member 8, one end of the elastic member 8 is fixedly connected with the inner wall of the tubular casing 1, the other end of the elastic member 8 is fixedly connected with the stirring member 2, and the elastic member 8 is made of corrosion-resistant material The elastic member 8 can be a spring or an elastic block. After the electromagnetic generator works, the stirring member 2 moves in the direction of the electromagnetic generator. At this time, the elastic member 8 is elongated. After the electromagnetic generator stops working, the elastic member 8 is reset. , Pull the stirring member 2 away from the electromagnetic generator, and the electromagnetic generator is continuously connected and disconnected, so that the stirring member 2 is continuously reciprocated in a straight line, the return mechanism is the elastic member 8, and the iron core 21 of the stirring member i...
