[0046] The implementation principle of this embodiment is as follows: During use, when the reactants inside the kettle body 1 are discharged, close the valve at the bottom of the kettle body 1 (not shown in the figure), then connect one end of the pipe body 24 to the external cleaning liquid, start the high-pressure pump 25, transport the cleaning liquid to the inside of the four connection heads 9 through the U-shaped pipe 26, the four connecting pipes 23, and the four hoses 11, and finally the cleaning liquid will be sprayed onto the inner wall surface of the kettle body 1 under high pressure through the four high-pressure nozzles 10;

Here, after the motor 4 and the waterproof motor 16 rotate forward for a certain period of time and then rotate in the reverse direction, it can be set through programming, which is a known prior art and will not be elaborated here. The output shaft of the motor 4 drives the rotating rod 5 to rotate. The rotating rod 5 drives the four connecting plates 7 to rotate reciprocally in the forward and reverse directions through the hollow sleeve 6. Subsequently, the four connecting plates 7 drive the four connecting heads 9 and the four high-pressure nozzles 10 to rotate through the two rollers 8. At the same time, the output shaft of the waterproof motor 16 drives the worm 14 on one side to rotate. The worm 14 on one side makes the worm 14 on the other side rotate through the cooperation with the sprocket one 17, the sprocket two 18, and the chain 19. At this time, the two worms 14 mesh with the two worm wheels 13, causing the two rollers 8 to rotate reciprocally in the forward and reverse directions. Subsequently, the four connecting heads 9 will drive the four high-pressure nozzles 10 to swing up and down reciprocally. While the cleaning liquid is cleaning the inner wall of the kettle body 1, the scraping frame 20 will rotate along with it to clean the bottom inner wall and the inner wall of the kettle body 1. Through the above structure, the four high-pressure nozzles 10 can rotate reciprocally and swing up and down reciprocally at the same time. The entire cleaning process is simple and convenient, and there is no need to open the tank for cleaning, which not only improves the cleaning efficiency of the enamel reactor but also reduces the labor intensity of the staff.

[0048] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
