A bevel gear 9 is fixedly installed on the outer side of the output end of the motor 8. The inner wall of the kettle body 1 is inlaid with a C-shaped ring 10. A plurality of bevel tooth grooves 11 are opened on the top of the C-shaped ring 10, and the bevel tooth grooves 11 are meshed with the bevel gear 9.

[0033] Specifically, the kettle body 1 can provide an opening space for the rotating groove 7, the rotating groove 7 can provide a rotation space for the rotation of the bevel gear 9, the C-ring 10 can provide an opening space for the bevel tooth groove 11, and the motor 8 can provide a rotational driving force for the bevel gear 9, so that the bevel gear 9 drives the C-ring 10 to rotate by utilizing the meshing action with the bevel tooth groove 11.

[0034] In this embodiment, a catalytic assembly 102 is provided on the inner wall of the kettle body 1, and the catalytic assembly 102 includes a plurality of bent rods 16. The catalytic assembly 102 is assembled to catalyze the compounds inside the kettle body 1 through the bent rods 16. A columnar hole is opened through the inside of the bent rods 16, and a catalytic film formed by a catalyst is plated on the surface of the bent rods 16. The catalytic film on the surface of each bent rod 16 is plated with a different catalyst; the catalytic assembly 102 also includes a plurality of rotating grooves 13, and the rotating grooves 13 are opened on the inner wall of the kettle body 1, and a fixed column 14 is fixedly installed on the inner side of the rotating groove 13, and a spring 15 is fixedly installed on the outer side of the fixed column 14, and the other end of the spring 15 is fixedly installed on the inner side of the columnar groove of the bent rod 16.

[0036] In this embodiment, a water spray assembly 103 is provided on the outer side of the stirring rod 6, and the water spray assembly 103 is assembled to spray the liquid evenly on the inner wall of the kettle body 1. The water spray assembly 103 includes a plurality of fixed rods 17, one end of the fixed rod 17 is fixedly installed on the surface of the stirring rod 6, and the other end of the fixed rod 17 is fixedly installed with a U-shaped ring 18, and a plurality of nozzles 19 are installed through the outer side of the U-shaped ring 18, and a ring cover 20 is installed on the inner side of the opening of the U-shaped ring 18 through a bearing sliding, and the top of the ring cover 20 is installed with two ends of a three-way pipe 21, and the three-way pipe 21 passes through the top of the kettle body 1.

[0037] Specifically, the three-way pipe 21 is fixedly connected to the kettle body 1 so that the ring cover 20 is fixed and does not rotate. Bearings are respectively installed on the outer side and the inner side of the ring cover 20. The ring cover 20 is connected to the opening of the U-shaped ring 18 through two bearings. When the stirring rod 6 drives the U-shaped ring 18 to rotate through the fixed rod 17, the two bearings facilitate the relative rotation of the ring cover 20 and the U-shaped ring 18.

[0038] Working principle: before use, determine the type of catalyst, then start the motor 8 to work, so that the output end of the motor 8 drives the bevel gear 9 to rotate clockwise, so that the bevel gear 9 drives the C-shaped ring 10 to rotate counterclockwise by meshing with the bevel tooth groove 11, and the C-shaped ring 10 drives the through hole 12 to rotate, so that the through hole 12 drives the bent rod 16 to rotate by the contact between the inner wall and the bent rod 16, so that the bent rod 16 inside the through hole 12 rotates clockwise to the inside of the rotating groove 13 with the fixed column 14 as the center, and then the through hole 12 continues to move to the position of the next rotating groove 13 counterclockwise of the rotating groove 13. When the through hole 12 is aligned with the rotating groove 13, the bent rod 16 inside the rotating groove 13 rotates counterclockwise and moves out of the inner side of the rotating groove 13 under the elastic force of the spring 15, and the bent rod 16 passes through the through hole 12 and rotates to the inside of the kettle body 1. Since the catalyst coatings on the surfaces of different bent rods 16 are different, the catalyst is replaced, and the motor 8 can be started again to continue to be replaced.

[0039] When the designated bent rod 16 rotates to the inner side of the kettle body 1, the synthetic resin compound is injected into the inner side of the kettle body 1 through the feed pipe 2, and the motor 4 is started to drive the stirring rod 6 to rotate clockwise, and the external diluent tube is connected to one end of the three-way pipe 21, and the diluent is injected into the three-way pipe 21, so that the diluent enters the inner side of the U-shaped ring 18 through the three-way pipe 21, and the diluent is sprayed on the inner wall of the kettle body 1 through the nozzle 19. The stirring rod 6 drives the U-shaped ring 18 to rotate through the fixed rod 17, so that the nozzle 19 sprays the diluent evenly into the kettle body 1. After the reaction is completed, cleaning water is injected into the kettle body 1 through the three-way pipe 21, so that the cleaning water is sprayed on the inner wall of the kettle body 1, which is convenient for cleaning the inner wall.
