Excessive triphosphate temperature can trigger side reactions and reduce the purity of the main product. Furthermore, the cooling kettles used in existing triphosphate production processes have poor cooling effects, cannot stir the triphosphates, and cannot cool and recycle the cooling water, resulting in water waste. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a cooling kettle for the production of triphosphates, which has the characteristic of cooling down the triphosphates produced at high temperatures during the production process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cooling vessel for the production of triphosphates, comprising an outer vessel body, support plates fixed on both sides of the lower end of the inner vessel body, an inner vessel body fixed on the upper end of the support plates, a feed pipe fixed on the lower side of one end of the inner vessel body, a discharge pipe fixed on the lower side of the rear end of the inner vessel body, a water inlet pipe fixed on the lower side of one end of the outer vessel body, a water outlet pipe fixed on the upper side of the other end of the outer vessel body, a thermometer installed at one end of the inner vessel body, a stirring assembly installed inside the inner vessel body, and a cooling assembly installed at the other end of the water outlet pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting up an outer vessel, discharges the high-temperature triphosphate during the triphosphate production process into the inner vessel through a feed pipe. Then, cold water is injected into the outer vessel through a water inlet pipe. The injection of cold water between the outer and inner vessels can cool the interior of the inner vessel, thereby achieving the effect of cooling the triphosphate. The internal temperature of the inner vessel can be monitored by a thermometer. The cooled triphosphate is discharged from the inner vessel through a discharge pipe. After use, the cooling water is discharged from the outer vessel through a water outlet pipe. By setting up the outer and inner vessels, the high-temperature triphosphate during the production process can be cooled, avoiding side reactions caused by excessively high triphosphate temperature and reducing the purity of the main product.

[0013] 2. This utility model, by setting up a stirring assembly, activates a motor to drive the rotating shaft when the triphosphate is cooling in the inner vessel. The rotating shaft stirs the triphosphate in the inner vessel through several stirring rods, improving the cooling effect of the triphosphate in the inner vessel. At the same time, the rotating shaft drives the horizontal and vertical scrapers to rotate, which can clean the inner wall of the inner vessel and prevent the triphosphate from adhering to the inner wall of the inner vessel and being difficult to clean.

[0020] Please see Figure 1-4 The present invention provides the following technical solution: a cooling kettle for the production of triphosphate, comprising an outer kettle body 1, with support plates 10 fixed on both sides of the lower end inside the outer kettle body 1, an inner kettle body 7 fixed on the upper end of the support plates 10, a feed pipe 8 fixed on the lower side of one end of the inner kettle body 7, a discharge pipe 9 fixed on the lower side of the rear end of the inner kettle body 7, a water inlet pipe 2 fixed on the lower side of one end of the outer kettle body 1, a water outlet pipe 5 fixed on the upper side of the other end of the outer kettle body 1, a thermometer 3 provided at one end of the inner kettle body 7, a stirring assembly 4 provided inside the inner kettle body 7, and a cooling assembly 6 provided at the other end of the water outlet pipe 5.

[0021] Specifically, valves are installed on the water inlet pipe 2, the feed pipe 8, and the discharge pipe 9, and a connecting flange is fixed at one end of each of the water inlet pipe 2, the feed pipe 8, and the discharge pipe 9.

[0022] By adopting the above technical solution, valves can be set to control the inlet water, inlet material, and outlet material of the inlet pipe 2, inlet material pipe 8, and outlet material pipe 9, and connecting flanges can be set to facilitate connection and fixation with external pipelines.

[0023] Specifically, the stirring assembly 4 includes a motor 41, a rotating shaft 42, stirring rods 43, horizontal scrapers 44, and vertical scrapers 45. The motor 41 is installed at the middle of the upper end of the outer vessel 1, and the output end of the motor 41 is provided with a rotating shaft 42. Several stirring rods 43 are fixed on the rotating shaft 42 inside the inner vessel 7. Horizontal scrapers 44 are fixed on both sides of one end of the rotating shaft 42 inside the inner vessel 7, and a vertical scraper 45 is fixed between the two horizontal scrapers 44.

[0024] By adopting the above technical solution, when the triphosphate is cooled in the inner vessel 7, the motor 41 is turned on to drive the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 stirs the triphosphate in the inner vessel 7 through several stirring rods 43, thereby improving the cooling effect of the triphosphate in the inner vessel 7. At the same time, the rotation of the rotating shaft 42 drives the horizontal scraper 44 and the vertical scraper 45 to rotate. The rotation of the horizontal scraper 44 and the vertical scraper 45 can clean the inner wall of the inner vessel 7, preventing the triphosphate from adhering to the inner wall of the inner vessel 7 and being difficult to clean.

[0025] Specifically, the cooling assembly 6 includes a cooling box 61, a water pump 62, a return water pipe 63, fins 64, and heat-conducting rods 65. The other end of the water outlet pipe 5 is connected to the cooling box 61. Several heat-conducting rods 65 are fixed inside the cooling box 61. Fins 64 are fixed at both ends of the heat-conducting rods 65. A water pump 62 is installed on one side of the rear end of the cooling box 61. The water pump 62 is connected to the outer vessel body 1 through the return water pipe 63.

[0026] By adopting the above technical solution, the temperature of the cooling water rises after use and is discharged into the cooling tank 61 through the outlet pipe 5. Several heat-conducting rods 65 in the cooling tank 61 transfer the heat in the water to the fins 64, thereby cooling the water. After the water is cooled in the cooling tank 61, the water pump 62 can be turned on to transport the water in the cooling tank 61 back to the outer vessel 1 through the return water pipe 63. By setting the cooling component 6, the used water can be cooled down, so that the cooling water can be recycled and water resources can be avoided.

[0027] Specifically, the sides of the horizontal scraper 44 and the vertical scraper 45 are tangent to the inner wall of the inner vessel 7, and the rotating shaft 42 is rotatably connected to the outer vessel 1 and to the inner vessel 7.

[0028] By adopting the above technical solution, the horizontal scraper 44 and the vertical scraper 45 are more closely attached to the inner wall of the inner vessel 7, resulting in a better cleaning effect on the inner wall of the inner vessel 7, and the rotating shaft 42 can rotate in the outer vessel 1 and the inner vessel 7.

[0030] By adopting the above technical solution, an observation window is set to observe the water level inside the outer vessel 1. The water pump 62 can draw water from the cooling tank 61 through the pipeline. A one-way valve is set on the end of the return water pipe 63 near the outer vessel 1 to prevent water inside the outer vessel 1 from flowing back into the return water pipe 63.

[0031] In this utility model, the thermometer 3 is a previously disclosed technology, and the selected model is PT100.

[0032] In this utility model, the motor 41 is a previously disclosed technology, and the selected model is 5IK120GN-CF.

[0033] The water pump 62 in this utility model is a previously disclosed technology, and the selected model is BJZ037.

[0034] The working principle and usage process of this utility model: When using the cooling kettle for triphosphate production, the device is installed in a suitable position. The high-temperature triphosphate produced during the production process is discharged into the inner kettle body 7 through the feed pipe 8. Then, cold water is injected into the outer kettle body 1 through the water inlet pipe 2. The injection of cold water between the outer kettle body 1 and the inner kettle body 7 can cool the inside of the inner kettle body 7, achieving the effect of cooling the triphosphate. The internal temperature of the inner kettle body 7 can be monitored by the thermometer 3. The cooled triphosphate is discharged from the inner kettle body 7 through the discharge pipe 9. After use, the cooling water is discharged from the outer kettle body 1 through the water outlet pipe 5. By setting up the outer kettle body 1 and the inner kettle body 7, the high-temperature triphosphate during the production process can be cooled to avoid the side reactions caused by excessively high triphosphate temperature and reduced purity of the main product. When the triphosphate is cooling in the inner kettle body 7, the motor 41 is turned on to drive it. The rotating shaft 42 rotates, and the rotation of the rotating shaft 42 stirs the triphosphate in the inner vessel 7 through several stirring rods 43, thereby improving the cooling effect of the triphosphate in the inner vessel 7. At the same time, the rotation of the rotating shaft 42 drives the horizontal scraper 44 and the vertical scraper 45 to rotate, which can clean the inner wall of the inner vessel 7 and prevent the triphosphate from adhering to the inner wall of the inner vessel 7 and being difficult to clean. After the cooling water is used, the temperature rises and it is discharged into the cooling tank 61 through the water outlet pipe 5. Several heat conduction rods 65 in the cooling tank 61 transfer the heat of the water to the fins 64, thereby cooling the water. After the water is cooled in the cooling tank 61, the water pump 62 can be turned on to transport the water in the cooling tank 61 back to the outer vessel 1 through the water return pipe 63. By setting up the cooling component 6, the used water can be cooled down, so that the cooling water can be recycled and water resources can be avoided.
