The inlet pipe 5 is connected to the external medium pipeline, and the outlet pipe 6 is connected to the external medium collection device. Hot medium steam or cold medium water is introduced into the jacket of the outer shell 1 to control the reaction temperature of the device. The device is started to fully stir the materials in the outer shell 1. After stirring, the raw materials are discharged from the outlet pipe 4.

[0031] A striking structure is provided on one side of the solid feed hopper 2. The striking structure uses a push rod 14 to strike the surface of the solid feed hopper 2 to prevent material adhesion. The striking structure includes an eccentric wheel 13, which is fixedly installed on the outer surface of the drive cylinder 8. A push rod 14 is provided on one side of the eccentric wheel 13. The push rod 14 slides through the surface of the support block 15. The support block 15 is fixedly installed on the inner wall of the outer shell 1. The surface of the push rod 14 is in contact with the outer surface of the solid feed hopper 2. A spring 16 is provided on the outer surface of the push rod 14. One end of the spring 16 is fixedly connected to the push rod 14, and the other end of the spring 16 is fixedly connected to the surface of the support block 15.

The push rod 14 slides on the surface of the support block 15 and stretches the spring 16. The push rod 14 strikes the surface of the solid feed hopper 2. Under the action of the continuously rotating eccentric wheel 13 and the spring 16, the push rod 14 reciprocates and continuously strikes the surface of the solid feed hopper 2 to prevent solid materials from adhering during the feeding process.

[0033] The interior of the outer shell 1 is equipped with a mixing structure. This structure achieves uniform mixing of materials through a lower stirring rod 10 and an upper stirring rod 11. The mixing structure includes four lower stirring rods 10, which are arc-shaped and fit snugly against the hemispherical inner wall of the outer shell 1. Above the lower stirring rods 10 are four upper stirring rods 11, which are round rods and parallel to the upper surface of the outer shell 1. Multiple upper stirring rods 11 are arranged in parallel, forming an inverted frustum shape inside the outer shell 1. The upper stirring rods 11 are fixedly mounted on the inner wall of the outer shell 1. The outer surface of the moving cylinder 9 is fixedly connected to the lower stirring rod 10.

[0034] like Figure 2 , Figure 3 and Figure 6As shown, during the mixing process of the material, the motor 7 is started, which drives the drive cylinder 8 to rotate, and the drive cylinder 8 drives the driven cylinder 9 to rotate, thereby causing the upper stirring rod 11 and the lower stirring rod 10 to rotate synchronously. The rotating upper stirring rod 11 and the lower stirring rod 10 mix the material. The lower stirring rod 10 fits against the hemispherical inner wall of the outer shell 1 to prevent the material from accumulating on the inner wall of the outer shell 1, while the upper stirring rod 11 increases the mixing range of the material above. At the same time, the screw ribbon 12 rotates with the driven cylinder 9 to axially convey the material, causing the material to tumble up and down in the device, improving the mixing efficiency and uniformity of the material.

[0035] Working principle: When using the stirring device for the production of fluorine protective agent, the material is fed in through the solid feed hopper 2 and the liquid feed pipe 3, so that the raw material falls into the interior of the outer shell 1. The medium is introduced into the interlayer of the outer shell 1 through the air inlet pipe 5 to control the reaction temperature of the device. The motor 7 is started, and the motor 7 drives the drive cylinder 8 to rotate. The drive cylinder 8 drives the eccentric wheel 13 to rotate. Under the action of the eccentric wheel 13 and the spring 16, the push rod 14 continuously hits the surface of the solid feed hopper 2 to prevent the solid material from adhering during the feeding process. The drive cylinder 8 drives the driven cylinder 9 to rotate, which in turn drives the upper stirring rod 11, the lower stirring rod 10 and the screw ribbon 12 to rotate, so as to fully stir the material in the outer shell 1. After the stirring is completed, the raw material is discharged from the discharge pipe 4, which increases the overall practicality.
