[0048] See Figures 1 to 4 As shown, according to some embodiments of the present invention, the calcium source raw material supply system 200 further includes a calcium source raw material storage device 240 and a fourth heater 250.

The dispersant supply system 400 includes a dispersant dissolving vessel 410, a sixth heater 420, and a fourth stirring device 430. The sixth heater 420 is connected to the dispersant dissolving vessel 410 to heat the dispersant in the dispersant dissolving vessel 410. The stirring end of the fourth stirring device 430 is located inside the dispersant dissolving vessel 410. The dispersant dissolving vessel 410 is connected to the reaction vessel 110.

[0061] By setting up a dispersant supply system 400, a dispersant at a set temperature can be provided to the reaction vessel 110 during the reaction to prevent the agglomeration of the prepared nanocrystal nuclei.

[0062] Specifically, the sixth heater 420 heats the dispersant in the dispersant dissolving vessel 410 while simultaneously stirring it using the fourth stirring device 430. This ensures that the dispersant reaches a suitable temperature and is uniformly dispersed during the dissolution process. The dispersant is also injected into the reaction vessel 110 at the same time as the calcium and silicon source materials, thus preventing the agglomeration of the prepared nanocrystal nuclei. The sixth heater 420 is preferably a water bath heater.

[0064] By installing a fifth control valve 440 and a dispersant discharge pump 450 on the pipeline connecting the dispersant dissolving vessel 410 and the reaction vessel 110, the flow rate and supply time of the dispersant can be precisely controlled, thereby ensuring that the dispersant is added to the reaction vessel 110 uniformly and as needed during the reaction process.

[0065] Specifically, the fifth control valve 440 can regulate the opening and closing of the pipeline between the dispersant dissolving vessel 410 and the reaction vessel 110, as well as the flow rate, controlling the amount and flow rate of the dispersant added to meet the needs of different reaction stages. By finely adjusting the fifth control valve 440, it can be ensured that the amount of dispersant added matches the required ratio for the reaction, avoiding situations where there is too much or too little dispersant, thus affecting the reaction effect. The dispersant discharge pump 450 is responsible for transporting the dispersant from the dissolving vessel to the reaction vessel 110 and ensuring a stable supply. The dispersant discharge pump 450 is used to drive the flow of the dispersant in the pipeline. The fifth control valve 440 is preferably an electromagnetic connecting valve, and the dispersant discharge pump 450 is preferably a peristaltic pump; the flow rate regulation function can also be achieved by controlling the pump speed of the peristaltic pump.

[0066] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the reaction system 100 further includes a temperature monitoring device 140, a pH monitoring device 150, and a pH adjuster storage device 160. The temperature monitoring device 140 and the pH monitoring device 150 are both located inside the reaction vessel 110, and the pH adjuster storage device 160 is connected to the reaction vessel 110.

[0067] By setting up a temperature monitoring device 140, a pH monitoring device 150, and a pH adjuster storage device 160, the temperature and pH value inside the reactor 110 can be monitored in real time, and the pH value inside the reactor 110 can be adjusted in real time to ensure that the reaction process is carried out under optimal conditions.

[0068] Specifically, the temperature monitoring device 140 can monitor the temperature inside the reactor 110 in real time to ensure that the reaction proceeds within a predetermined temperature range. The pH monitoring device 150 can detect the pH value inside the reactor 110 in real time to ensure that the pH value is maintained within the optimal range during the reaction. The pH adjuster storage device 160 is connected to the reactor 110 and can automatically add an appropriate amount of pH adjuster to the reactor 110 based on feedback from the pH monitoring device to adjust the pH value inside the reactor 110.

[0069] As an example, the temperature inside the reactor 110 is controlled at 50°C to 60°C by a temperature monitoring device 140 and a first heater 120, and the pH value inside the reactor 110 is controlled at 11±0.2 by a pH monitoring device and a pH adjuster storage device 160.

[0070] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, a seventh control valve 170 and a pH adjuster discharge pump 180 are provided on the pipeline connecting the pH adjuster storage device 160 and the reaction vessel 110.

[0071] By installing a seventh control valve 170 and a pH adjuster discharge pump 180 on the pipeline connecting the pH adjuster storage device 160 and the reactor 110, the amount and flow rate of the pH adjuster can be precisely controlled, thereby achieving precise adjustment of the pH value in the reactor 110.

[0072] Specifically, the seventh control valve 170 regulates the flow rate in the pipeline, controlling the flow rate and dosage of the pH adjuster. By adjusting the opening of the control valve, the rate at which the adjuster enters the reactor 110 can be precisely controlled, ensuring that the addition of the pH adjuster meets the reaction requirements. The pH adjuster storage device 160 is responsible for transporting the pH adjuster from the storage device to the reactor 110.
