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.

Batching system can realize measuring and proportioning conveying for many kinds of materials, featuring accurate measuring, fast speed, no abrasion to materials and high measuring precision. It is characterized by high degree of automation, simple operation, environmental protection, accurate feeding and high proportioning accuracy. Through the computer control center, the whole production process can be viewed, and the operation process can be effectively controlled, which can eliminate the errors that may be caused by human operation. ​

Batching system realizes intelligent and networked management of small material batching, so that finished products and raw materials can be traced in both directions, production decision-making and production control are seamlessly connected, production execution is improved, and real-time and accurate production data are used as the basis for managers' decision-making, so as to prevent the occurrence of quality accidents. Help customers to solve the dosage error prevention, improve dosage precision, quality traceability products, intuitive image, over the limit of the sound and light alarm prompts the application of bar code to effectively prevent the occurrence of the wrong raw materials raw material lot number bar code and finished product lot number bar code fixed in the bar code block can be reused.

Dosing system is a kind of production equipment used for industrial processing of different powder or liquid materials according to a certain proportion of automatic and accurate proportioning, usually composed of weighing system, weighing control instrument, PLC system and upper computer. Including the storage body of raw materials, transportation body, weighing and batching body, dust removal body, material mixing body and other equipment. Batching mode can be reasonably selected according to the industry characteristics, production process requirements, specific material characteristics, "incremental" or "decremental" weighing mode, with a single hopper single material, single hopper multi-material, multi-bucket multi-material and other modes of operation.

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.

According to its specific production process and process equipment, the reactor weighing can achieve stable product quality through automatic monitoring and control of production parameters such as temperature, pressure, flow rate and batching accuracy. After particle size, moisture, viscosity and other quality testing, in a specific temperature, sealed and other environment storage and transportation. The use of computer for online monitoring and management has higher requirements for weighing speed, weighing accuracy, system compatibility and scalability.

The weighing of the reaction tank is transmitted from the industrial computer in the control center to the electronic scale and PLC controller through the communication line, and the weight of each link is collected and displayed, and the fast feeding and slow feeding strategies are adopted in different weight stages to improve the efficiency and the measurement accuracy of the electronic scale. When the ingredients reach the target value, the output stop measurement signal, and the related valves and pumps are closed by PLC control. At the same time, the action of unloading the reactor is completed, and the measuring instrument is automatically zeroed and peeled.

Weighing the reaction pot by several raw material conveyor screw to the raw material in the order of the set to the metering scale, each raw material according to the automatic control system set the weight of the conveyor in turn, after the weight of the raw material is measured, and then by the metering scale of the discharge spiral to all the raw materials to the downstream equipment (cache bin, or direct pipeline connection), while starting the vacuum conveyor or valve. The raw material is sent to the waiting bin located above the main engine, where the weight of the raw material is completed.
