If the weight of the slurry added is less than the process preset data, the slurry addition module controls the flow rate or addition time of the slurry; The pure water delivery module adds the required pure water into the reactor. The pH sensor in the pure water delivery module monitors the pH value of the delivered pure water in real time. The flow meter in the pure water delivery module monitors the flow rate of the delivered pure water in real time. The pure water delivery module transmits the real-time monitored pH value of the delivered pure water and the flow rate of the delivered pure water to the control module. The control module receives, records, and stores the real-time monitored pH value of the pure water and the flow rate of the pure water, and compares the received values with the process preset data. If the weight value of the pure water added is less than the process preset data, the pure water addition module is controlled to increase the flow rate or time of pure water addition. If a sudden change in the pH value of the pure water is detected, the pure water addition module is controlled to stop the addition immediately. The alkaline substance delivery module adds the required alkaline substance into the reactor. The pH sensor in the alkaline substance delivery module monitors the pH value of the delivered alkaline substance in real time. The flow meter in the alkaline substance delivery module monitors the flow rate of the delivered alkaline substance in real time. The alkaline substance delivery module transmits the pH value and flow rate of the alkaline substance monitored in real time to the control module. The control module receives, records, and stores the pH value of the alkaline substance and the flow rate of the alkaline substance that are monitored in real time, and compares the received values with the process preset data. If the weight value of the alkaline substance that is added is less than the process preset data, the alkaline substance addition module controls the flow rate or addition time of the alkaline substance. If the pH value of the alkaline substance is monitored to change suddenly, the alkaline substance addition module is controlled to stop the addition immediately. The coating material feeding module adds the coating material into the reactor, monitors the flow rate of the coating material into the reactor in real time, and transmits the monitored flow rate of the coating material into the reactor to the control module; The control module receives, records, and stores the flow rate of the coating material delivered by the coating material module monitored in real time, and compares the received value with the process preset data. If the weight value of the delivered coating material is less than the process preset data, the coating material delivery module is controlled to deliver the coating material at a flow rate or delivery time. The heating module heats the slurry in the reactor, and the temperature sensor and pressure sensor in the reactor monitor the temperature and pressure values in the reactor in real time, and transmit the monitored real-time temperature and pressure values to the control module; The control module receives, records and stores the temperature and pressure values monitored in real time, compares the received temperature and pressure values with the process preset temperature and pressure values, and controls the heating power and heating time of the heating module according to the process preset temperature and pressure values; The iron removal module removes ferromagnetic substances from the slurry. The control module uses the parameters obtained by the above modules and the data of the iron content in the slurry to generate influencing factors for comparison and optimize the process parameters. The control module controls the unloading speed of the unloading module; The coating quality of each batch of products is tested, and the parameters obtained from each module are compared with the database generated by the coating quality test data and the influencing factors. The data in the database is iterated to obtain the optimal process data.
10. The control method of an automatic water washing reactor according to claim 9, characterized in that: When the control module controls the unloading speed of the unloading module, the control module controls the cleaning module to clean the inside of the reactor according to the unloading speed of the unloading module.
