[0002] Chlorination reaction generally refers to the reaction of introducing chlorine into a compound. The current chlorination kettle generally includes a kettle body, a stirring device is provided in the kettle body to stir the material in the kettle body, and a chlorine inlet is provided on the kettle body. Chlorine gas is input into the kettle body through the chlorine inlet to make the material undergo a chlorination reaction. Since the inner wall of the chlorination kettle is very easy to adhere to reaction residues after a long period of use, and the residual reactants and chlorine in the chlorination kettle when it is opened pose a safety hazard, it is necessary to use a chlorination kettle with a sealed cleaning device.

[0028] Working principle:

[0029] When in use, first open the valve of the discharge pipe 12 to empty the reaction product inside the kettle body 1. When cleaning the kettle body 1, the cleaning water is pressurized and then introduced into the hollow stirring shaft 7 through the water inlet pipe 4, so that the cleaning water is poured into the hollow stirring rod 10 in a diversion manner. Since the hollow stirring rod 10 is provided with a baffle 15 with a corrosion-resistant film 17 corresponding to the water nozzle 14, and a water hole 16 is provided on the surface of the baffle 15, the impact force of the cleaning water forces it to pass through the water hole 16 and reopen the corrosion-resistant film 17 until the cleaning water is sprayed from the inclined water nozzle 14 to the inner wall of the kettle body 1. At this time, the motor 5 is started to drive the small gear 6 fixed at its output end to rotate. Since the small gear 6 is meshed and connected with the large gear 8 on the upper surface of the hollow stirring shaft 7, the motor 5 can drive the hollow stirring shaft 7 to rotate, and the rotating hollow stirring shaft 7 drives the two vertical scrapers 11 provided on the upper part and the scrapers provided on the bottom. The arc scraper 13 rotates to make the cleaning range of the inner wall of the kettle body 1 more comprehensive. The corrosion-resistant film 17 is connected to the baffle 15 by corrosion-resistant screws and strong glue, and the surface of the corrosion-resistant film 17 is not provided with a structure that is easy to fall off, so as to avoid the situation where the brush cover of the traditional cleaning device falls off and contaminates the reaction product. The arc magnet 18 arranged at the edge of the corrosion-resistant film 17 can maintain the adsorption effect with the baffle 15 without cleaning. At the same time, a sealing shell 19 is sleeved at the connection between the water inlet pipe 4 and the hollow stirring shaft 7, and the ball bearing 20 embedded in the sealing shell 19 is sleeved on the periphery of the port at the top of the hollow stirring shaft 7, and the outer wall of the sealing shell 19 is connected to the outer wall of the kettle body 1 by an L-shaped support rod 9. While maintaining the sealing of the connection between the two, the water inlet pipe 4 and the hollow stirring shaft 7 can rotate relative to each other, which is beneficial to the rotation of the hollow stirring shaft 7 and also facilitates the stable supply of cleaning water.
