[0002] Sodium carbonate solution, as an important chemical raw material, is widely used in glass manufacturing, metallurgy, textiles, food processing and other fields. In these production processes, parameters such as the concentration and temperature of sodium carbonate solution directly affect product quality and production efficiency. Therefore, the accurate preparation of sodium carbonate solution is crucial. This requires a professional sodium carbonate batching device to ensure that the sodium carbonate solution that meets production requirements is prepared by precisely controlling the raw material ratio, temperature, stirring speed and other conditions. However, traditional sodium carbonate batching devices have shortcomings. On the one hand, their temperature control systems are not perfect, with low heating and cooling efficiency, making it difficult to accurately control the reaction temperature. This can easily lead to incomplete reactions or side reactions caused by excessively high temperatures, affecting product quality. On the other hand, traditional devices also lack in terms of ease of operation and safety. Raw material addition and solution discharge are cumbersome, lacking effective observation and monitoring structures. Furthermore, the devices have poor sealing, posing a risk of material leakage. They also lack reliable safety protection measures, failing to release pressure in time when abnormal pressure occurs, which can easily lead to safety accidents. These problems seriously restrict production efficiency and safety. Therefore, we propose a sodium carbonate batching device. Utility Model Content

[0023] Working Principle: Raw materials such as sodium carbonate and solvents are added to the inner layer of the preparation vessel through the top stirring discharge port 20. The hinged lid design facilitates opening and closing; after addition, it is closed and sealed. Simultaneously, the stirring shaft of the stirring device extends into the vessel through the stirring discharge port 20 to stir the materials, ensuring rapid and uniform mixing under centrifugal and shear forces, guaranteeing a complete reaction. Precise temperature control relies on the unique double-layer structure of the preparation vessel. When heating is required, steam enters the gap between the inner and outer layers from the steam inlets 8 on both sides of the outer cylindrical surface. The steam releases heat, which is conducted to the inner material through the vessel wall, achieving heating. To prevent overheating, cooling water circulation is controlled through the first cooling water inlet 2 and the first cooling water outlet 5 outside the bottom drain port 4, and the second cooling water inlet 6, the third cooling water inlet 7, and the second cooling water outlet 10 on the outer cylindrical surface. Cooling water flows into the gap from the inlets, absorbs excess heat, and then flows out from the outlets. To ensure temperature stability, the vent 21 at the bottom of the fixed block 9 is used to discharge residual steam or non-condensable gases in the gap, ensuring heat exchange efficiency. During the reaction, the first thermometer port 12 and the second thermometer port 18 at the top are symmetrically distributed, and high-precision thermometers are inserted to monitor the temperature in real time. The manhole 11 with a sight glass and the sight glass port 16 facilitate the operator's observation of the reaction status and liquid level of the material in the vessel. When it is necessary to perform quality testing on the material, samples can be extracted through the sampling port 22. The spare group can be added as needed to enhance the functional expandability of the device. To ensure the safe operation of the device, an explosion relief port 17 is set at the top. When the pressure in the vessel exceeds the set value, the explosion relief device will automatically open to release pressure and prevent explosion accidents. After the reaction is completed, the qualified sodium carbonate solution is discharged through the bottom discharge port 3. The drain port 4 is used to discharge residual cooling water or steam condensate in the gap, ensuring the cleanliness of the equipment and safety for the next use.
