[0035] Specifically, the mixing tank 1 is used to accommodate various raw materials and reaction mixtures in the preparation process of sodium hypochlorite, providing a reaction space for the entire preparation process. The stirring cover 2 is used to prevent materials from splashing out of the mixing tank 1 during the stirring process, and at the same time, it can reduce the interference of external impurities entering the tank and causing interference with the reaction. The function of the connecting frame 16 is to stably install the rotating shaft 14 in the stirring assembly on the outside of the mixing tank 1, provide support and positioning for the rotation of the rotating shaft 14, and the rotating shaft 14 is used to drive the square rod 15 to rotate, thereby causing the stirring rod 16 to perform a rotating stirring action. The pulley 13 is used to cooperate with other pulleys to transmit power to the rotating shaft 14 through belt transmission so that it can rotate stably. The square rod 15 is used to connect the stirring rod 16 and the rotating shaft 14, and can slide inside the rotating shaft 14 to realize the up and down movement of the stirring rod 16. The stirring rod 16 is used The invention is used to stir the materials in the mixing tank 1, mix the materials evenly, and promote the reaction. The inclined plate 17 is used to interact with the roller 19 during the rotation process, so that the square rod 15 can slide up and down, thereby enhancing the effect and range of stirring. The connecting frame 18 is used to install the roller 19 and provide a support structure for the rotation of the roller 19.

[0036] Reference Figure 2 - Figure 5The cleaning assembly includes a gear ring 20 and two support blocks 11. The outer side of the gear ring 20 is rotatably connected to the inside of the mixing tank 1. The outer side of the support block 11 is fixedly connected to the top of the connecting frame 6. A motor 10 is fixedly connected between the two support blocks 11. The output end of the motor 10 is fixedly connected to a rotating shaft 23. The outer side of the rotating shaft 23 is fixedly connected to a pulley 12. The bottom end of the rotating shaft 23 is fixedly connected to a gear 24. The gear 24 is meshed with the gear ring 20. A connecting rod 21 is fixedly connected to the bottom of the gear ring 20, and a scraper rod 22 is fixedly connected to the outer side of the connecting rod 21.

[0037] Specifically, the gear ring 20 rotates within the mixing tank 1, preparing to subsequently drive the scraper 22 to rotate and clean the tank walls. This rotation is achieved by meshing with a gear 24. Two support blocks 11 are fixedly connected to the top of the connecting frame 1 6 to support the motor 10 and ensure that the motor 10 can be stably installed in its position. The motor 10 is used to provide power, driving the rotating shaft 23 to rotate, providing a source of power for the entire cleaning and mixing components. The rotating shaft 23 transmits the power output of the motor 10. On the one hand, it drives the rotation of pulley 12 to provide power to the mixing component via a belt drive, and on the other hand, it drives the rotation of the gear 24 at the bottom. Pulley 12 is used to cooperate with other pulleys, such as pulley 2 13, to transmit power through a belt connection, ensuring the normal operation of the mixing component. The gear 24 meshes with the gear ring 20, driving the gear ring 20 as it rotates, thereby transmitting the power of the motor 10 to the gear ring 20. The connecting rod 21 is used to connect the gear ring 20 and the scraper rod 22, so that the gear ring 20 can drive the scraper rod 22 to rotate synchronously. The scraper rod 22 is used to scrape and clean the inner wall of the mixing tank 1 as the gear ring 20 rotates, preventing material from remaining on the tank wall and scaling, and ensuring the cleanliness of the interior of the mixing tank 1.

[0038] Reference Figure 1 - Figure 5 The pulley 12 is connected to the pulley 2 13 by a belt, the outer side of the rotating shaft 23 is rotatably connected to the inside of the connecting frame 1 6, the outer side of the swash plate 17 is arranged between the two rollers 19, the bottom end of the bottom rod 8 is rotatably connected to the bottom wall of the mixing tank 1, the bottom of the mixing tank 1 is fixedly connected to the discharge port 4, the outer side of the discharge port 4 is provided with a valve 1 5, the outer side of the mixing tank 1 is fixedly connected to the base frame 3, the inside of the connecting frame 1 6 is fixedly connected to the feed port 7, and the outer side of the feed port 7 is provided with a valve 2 9.

[0039] The bottom end of the bottom rod 8 is rotatably connected to the bottom wall of the mixing tank 1 to provide a stable bottom support and guide for the up and down sliding of the square rod 15, ensuring that the square rod 15 can move along the correct trajectory during the sliding process, thereby ensuring the normal operation of the mixing assembly and the stirring action. The stable implementation of the work, the discharge port 4 fixedly connected to the bottom of the mixing tank 1 is used to discharge the finished sodium hypochlorite solution in the tank from the mixing tank 1 after the preparation of sodium hypochlorite is completed, so as to facilitate subsequent collection, storage or use. The valve 5 provided on the outside of the discharge port 4 is used to control the opening and closing state of the discharge port 4, adjust the discharge speed and discharge amount of the sodium hypochlorite solution according to actual needs, and ensure the orderly progress of the discharge process. The base frame 3 fixedly connected to the outside of the mixing tank 1 is used to provide a stable support for the mixing tank 1, so that it can be stably placed in the corresponding work site to prevent shaking and other conditions from affecting the normal operation of the equipment and the development of stirring, cleaning and other work. The feed port 7 fixedly connected inside the connecting frame 6 is used to transport various raw materials required for the preparation of sodium hypochlorite, such as sodium hydroxide solution, chlorine gas, etc., into the mixing tank 1 to ensure that the reaction raw materials can smoothly enter the tank for reaction. The valve 9 provided on the outside of the feed port 7 is used to control the opening and closing of the feed port 7, accurately control the feeding time and feeding amount of the raw materials, and ensure the accuracy and rationality of the addition of raw materials during the preparation process.

[0040] Working principle: When in use, first, when feeding, the raw materials required for preparing sodium hypochlorite can be added into the mixing tank 1 through the feed port 7 by opening the valve 2 9 on the outside of the feed port 7, and the motor 10 is started, and its output end drives the rotating shaft 23 to rotate. When the rotating shaft 23 rotates, on the one hand, it drives the pulley 12 to rotate. Since the belt between the pulley 12 and the pulley 2 13 is connected, the pulley 2 13 rotates accordingly, and then drives the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 causes the square rod 15 to rotate, and the square rod 15 drives the stirring rod 16 to stir the material in the mixing tank 1. The swash plate 17 on the stirring rod 16 also rotates accordingly, and the swash plate 17 moves between the two rollers 19. Due to the special shape of the swash plate 17 and the interaction with the roller 19, the square rod 15 slides up and down in the rotating shaft 14, thereby driving the stirring rod 16 to reciprocate up and down while stirring, thereby enhancing the stirring effect and making the material mixing more sufficient and uniform.

[0041] On the other hand, the gear 24 at the bottom end of the rotating shaft 23 rotates with the rotating shaft 23. Since the gear 24 is meshed with the gear ring 20, the gear ring 20 rotates in the mixing tank 1. The connecting rod 21 at the bottom of the gear ring 20 drives the scraper 22 to rotate. The scraper 22 can clean the inner wall of the mixing tank 1 to prevent the material from remaining or scaling on the tank wall.

[0042] After the material is stirred, open the valve 5 outside the discharge port 4 and the sodium hypochlorite solution can be discharged from the discharge port 4.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
