[0018] Specifically, the temperature of the homogeneous stirring kettle 33 is automatically and precisely controlled: During production, tap water is first input into the homogeneous stirring kettle 33. The globe valve is in the normally open state. The angle seat valve is automatically opened to first pass steam to quickly heat the tap water. After heating to the set temperature, solid powder materials are put in. After homogeneous stirring is completed, the liquid raw materials of the product are added. This liquid raw material is sensitive to temperature, and accurate temperature control is required during heating (the temperature is within ±2°C and cannot exceed the temperature by 2°C). At this time, heating is changed to use hot water for heating. When the temperature exceeds the limit, tap water is used for cooling. When using hot water for heating, all angle seat valves on the steam pipeline are closed, and then the angle seat valve is automatically opened. Subsequently, one of the water pumps (angle seat valve, water pump or angle seat valve, water pump) is opened to heat the homogeneous stirring kettle 33 with hot water. When the set temperature is reached, heating is stopped. When cooling is required, the hot water angle seat valve is closed, and the angle seat valve and the angle seat valve are automatically opened to supplement tap water to the homogeneous stirring kettle 33.

[0019] Further, the temperature of the hot water in the water heating tank 1 is controlled: The temperature sensor senses the temperature of the hot water in the water heating tank 1. When it is lower than the set value, the steam angle seat valve is opened to control the hot water to rise in temperature. The heating is automatic heating. The globe valve is in the normally open state. The angle seat valve is automatically opened. The steam control valve 7 automatically adjusts the opening of the valve core according to the temperature feedback of the temperature sensor, and the angle seat valve is opened to make the hot water return for heating.

[0020] Specifically, the liquid level of the water heating tank 1 is controlled: The magnetic flap liquid level sensor 9 monitors the water level. When it is lower than the set water level, automatic water replenishment is carried out. The manual ball valve is in the normally open state. The angle seat valve is automatically opened. When the set liquid level is reached, the angle seat valve is automatically closed.

[0021] Further, the following are the technical parameters related to some main equipment

[0022] Technical parameters related to the water heating tank 1: Design temperature 100°C, coil temperature 145°C, coil design pressure 0.3 MPa; Technical parameters related to the steam control valve 7: Control signal 4 - 20 ma, working temperature -17 - +230°C, stroke 25 mm; Technical parameters related to the temperature sensor: Output signal 4 - 20 ma, accuracy 0.2%, temperature range 0 - 150°C, insertion depth 50 mm; Technical parameters related to the magnetic flap liquid level sensor 9: Working temperature -10 - 150°C, output signal 4 - 20 ma, measurement range 0 - 1 m; Technical parameters related to the water pump: Flow rate 10m 3 / h, power 2.2 kw, head 43 m, motor speed 2900 r / min.
