The accurate and reliable measurement of various raw materials added to the reactor and the advanced and effective control methods for the various production processes are undoubtedly the necessary factors to give full play to the role of equipment and systems and ultimately ensure the smooth production and quality of the final product. This production line control system PLC uses the German SIEMENS company S7-300 series products to ensure the advanced technology and stability of the system technology. The color touch screen of EASY-VIEW company is selected as the man-machine interface. The high-speed dispersion adopts LG company frequency conversion control. The high-speed agitator can be arbitrarily adjusted from 0-750 r / min to meet the different requirements of the stirring speed in each stage of production, thereby ensuring the entire control System reliability. PLC collects speed, temperature, pressure, flow, valve switches and equipment operating status signals from field instruments, and realizes real-time and fast information exchange with human-machine interface through RS485 interface. In order to ensure reliability, all temperature, pressure and other process indicators adopt remote and on-site measurement and display 2 sets of systems. Through on-site process parameter measurement-signal transmission-centralized display and program control-signal feedback-on-site execution process, automatic control and adjustment of temperature and pressure in the production process are realized. Vortex flowmeters are generally used for the measurement of main liquid materials, and the measurement accuracy is above 0.5. The operator sets the required amount before the liquid material is delivered, and then presses the start button, the valve automatically opens, and the liquid material pump automatically starts the liquid material delivery. When the liquid material reaches the set value, the liquid material pump automatically stops and the valve is automatically controlled Automatic shutdown, the entire liquid material conveying process is automatically completed without human intervention. In order to ensure the accuracy of the measurement, we have also equipped an imported electronic weighing and weighing system for each reactor, and performed a secondary measurement check on the amount of raw materials added to the reactor after a single measurement, with an accuracy of ± 0.5 kg. . At the same time, in order to ensure the accurate measurement of the final product, the production line is equipped with an automatic canning machine for finished products. The entire process of canning and capping is automatically completed with an accuracy of ± 10 g.
