The automatic batching equipment is connected to the field weighing instrument through the bus, the control field equipment, the frequency converter of the weighing feeder, etc., which has a high degree of intelligence and fast processing speed. In the process of batching production, the main material and auxiliary materials are matched in a certain proportion to complete the measurement of the transported material. It is mainly responsible for real-time control of conveying and weighing process, fault detection, display and alarm, and adjustment of spiral speed by output signal to inverter.

The intelligent batching system is used for the cascade control of material proportion, temperature and jacketing temperature. According to the process requirements, the reaction materials A, B and C are pre-added into the three storage tanks in a certain proportion. The storage tank liquid level meter adopts the reed float type liquid level meter, and the two normally open reed switches are respectively located in the upper and lower positions of the liquid level meter. The liquid level gauge outputs the On or Off status information.

The reaction kettle industrial control system realizes the dosage control of the reaction kettle, the serial control of the temperature inside the reaction kettle and the jacket temperature. It includes creating real-time database, making process flow diagram and animation connection, designing operation strategy and window configuration. The control process is to create a script program component in the "Startup Strategy" of the MCGS "Operation Strategy" window, write a program to open all solenoid valves except the feed valve, start the timing tank with a 2-minute delay so that all tanks and reactors will be emptied at the beginning of the system operation, and set the cycle time for all tanks and reactors to be emptied at the beginning of the system operation. Set the period to 200 milliseconds, add a script program component to it, and write a control program based on the flowchart.

The automatic control system of the reaction pot transmits the control command to the PLC measurement and control terminal through the high-speed network, and implements the decentralized management of each unit. Integrating computer technology, automatic control, communication technology, weighing technology as a whole, its control function is perfect, display, operation is centralized, data processing is convenient, installation, maintenance is simple, the system is easy to expand. In the structure of the computer centralized control system to solve the problem of "risk concentration", to achieve "management centralized risk dispersion", the system is stable and reliable to meet the use in the continuous production process.

Automated dosage system adopts reducer and mixer with various components, when adding a small amount of powder, it is necessary to configure liquid spraying device, which is more conducive to the uniform dispersion of powder mixed in the main material, so as to achieve the purpose of uniform mixing.

The reaction pot control system sets the discharge amount of each material through the weighing controller, and stores the formula. After pressing the START key, the PLC will issue the feeding instruction, and the feeding will start at this time. The valve of the middle metering hopper will be closed, the material will fall into the metering hopper, and the valve of the liquid material hopper will be opened. PLC issued a stop feeding instruction, at this time to stop the operation.

In order to ensure the accuracy of dosage, the reaction tank control system uses frequency converter to control the screw feeding speed so as to achieve the purpose of accurate dosage, and sets the dosage ratio through the two-way communication between the computer and the meter, and the serial port communicates with PLC. According to the actual process of dosage technology to reflect the dynamic screen in the form of loading, dosage, feeding and related equipment operating state, according to the operating data can be given to the ratio or feeding amount, and truly reflect the dosage state, the ideal equipment for continuous dosage and measurement of materials.

The automatic control system of the reactor is composed of automatic batching design, feed and discharge all controlled by computer, dynamic weighing module, precision amplifier, A/D converter, microcomputer, monitor, printer and execution system. The weight required for various materials is set through the touch screen, and automatically transported to the ingredients in order for automatic weighing and flow control, so as to achieve accurate measurement and batching.

Weighing equipment is a complete set of automation equipment to realize dynamic weighing and batching control through electrical control management and visualization man-machine software configuration. The electrical control part of the system adopts Siemens PLC, which is programmed and controlled according to the production requirements; the software adopts the man-machine configuration, which controls the weight and flow of the material loaded into the weighing hopper according to the process requirements, through the monitoring system and the PLC program.
