[0029] The steam regulating valve 2 is located in the steam intake pipeline and is provided with a bypass for adjusting the steam intake amount. The steam pressure transmitter 3 is located downstream of the steam regulating valve 2 and is used to accurately measure the intake steam pressure to ensure the heating rate.

[0030] The extraction kettle is provided with an extraction kettle temperature transmitter 1 installed in the extraction kettle temperature measuring temperature sleeve, which is used to accurately measure the temperature in the extraction kettle to ensure that the reaction temperature of the extract liquid is kept within the normal range. The extraction kettle temperature transmitter 1 is interlocked with the steam regulating valve 2 to stably adjust the temperature in the kettle, and is interlocked with the circulating water outlet switch valve 4 and the circulating water inlet switch valve 5 to emergency cool down after over-temperature.

[0031] The intelligent liquid detector 7 is located downstream of the extraction kettle discharge valve 6, and is equipped with an observation mirror below for online monitoring of the real-time data of the extraction liquid and automatic control of subsequent valve switches. A three-way valve is arranged below the intelligent liquid detector 7, and a steam purge switch valve 8 is located at the three-way valve below the intelligent detector 7, which is used to purge the material pipe after the discharge is completed to prevent the accumulation of the extraction liquid.

[0032] The utility model includes an extraction kettle reaction stratification system and an extraction liquid concentration detection automatic discharging system. The whole system is centrally controlled and managed. The central control host is electrically connected to each valve and is centrally controlled through an operation interface. The reaction system device mainly includes a steam regulating valve, an operation interface, a steam pressure transmitter, an extraction kettle temperature transmitter, a circulating water inlet switch valve, and a circulating water outlet switch valve; the extraction liquid concentration detection automatic discharging system includes an extraction kettle discharging switch valve, an intelligent liquid detector, a steam purge switch valve, a liquid phase discharging regulating valve, a water phase discharging switch valve, a liquid phase receiving switch valve, and a water phase receiving switch valve.

[0033] During operation: on the premise that the material has been statically layered, the data used for layering and the direction of the liquid phase and the water phase are checked through the operation interface, and the layering in the extraction kettle is controlled. First, the bottom valve of the extraction kettle is automatically opened, and then after the intelligent liquid detector detects the data corresponding to the lower liquid phase, the liquid phase discharge regulating valve is opened to the set opening, and the liquid phase receiving kettle switch valve is automatically opened at the same time; the lower liquid phase is discharged normally; after the intelligent liquid detector measures the data of the middle emulsified layer, the liquid phase discharge regulating valve is automatically reduced to the set opening (to prevent excessive discharge, vortex generation, and inaccurate measurement); after the intelligent liquid detector measures the data of the upper water phase, the bottom valve of the extraction kettle is closed, and the liquid phase discharge regulating valve is automatically opened to the maximum; the steam purge switch valve is opened to purge the pipeline, and the steam purge switch valve is automatically closed after the set purge time; the liquid phase discharge regulating valve and the liquid phase receiving kettle switch valve are closed, and the automatic layered discharge of the lower liquid phase is completed. After the lower liquid phase is automatically discharged, the upper water phase is automatically discharged through the operation interface. First, the bottom valve of the extraction kettle is automatically opened. Then, after the intelligent liquid detector detects the data corresponding to the upper liquid phase, the water phase discharge switch valve is opened. At the same time, the water phase receiving kettle switch valve is automatically opened to discharge the lower liquid phase normally. After the intelligent liquid detector cannot detect the upper layer data (the data is reset to zero), the discharge bottom valve is closed, and then the steam purge switch valve is opened to purge the pipeline. After the purge setting time, the steam purge switch valve is closed; the water phase discharge switch valve and the water phase receiving kettle switch valve are automatically closed. At this point, the extraction automatic stratification discharge is completely completed.

[0034] Automatically discharging materials in layers according to the above process can save labor and achieve better stratification effects, so that the quality of the liquid phase and the water phase after stratification is higher than that of manual stratification, and subsequent reactions can be carried out faster and better.
