The reactor feeding system mainly consists of touch screen weighing instrument and automatic pneumatic valve, transfer pump, mixing tank and weighing module. Through the automatic control program of the touch screen of weighing instrument, it can automatically mix and proportion all kinds of raw and auxiliary materials in different order and temperature, realizing the ideal automatic liquid dispensing equipment for finished product manufacturing.

After the automatic Dosage system is activated, the user will set the injection volume required for this liquid dispensing on the human-machine interface, and the programmable controller system will automatically add liquid and make judgment according to the set value. When the weight collected by the weighing module reaches the set weight, the weighing instrument system will automatically close the liquid filling valve.The weight control accuracy of PLC system can reach 0.1%, which greatly improves the control accuracy of liquid distribution. It really realizes the integrated process of fully automatic weighing and dosing system.

The feeding system picks up the weight through the pressure weighing module, and amplifies and filters the picked up weight signal into A/D converter for analog to digital conversion, then sends it to the weighing instrument for signal analysis and processing, and the result is outputted to the industrial control through the RS232C communication serial port, and at the same time, it makes the corresponding reaction and executes the corresponding operation according to the result of the signal. Adopted the industrial control machine batching centralized control mode, is by a host and more than one slave machine through the network link up, the host will control the task to each slave machine to complete. The whole industrial control machine batching is divided into industrial control Electronic scale and weighing instrument.
