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.
020-34563445The kettle Weighing system is operated by pressing the start button, the system touch screen is activated and the weighing touch screen is cleared to zero. Then give the raw material fast feeding and slow feeding effective signal, the system opens the valve to start the material pump, start the raw material fast feeding process (i.e. at the same time open the two feed valves), at the same time the touch screen start to read the signal of the Electronic scale at any time tracking, when the weight is close to reach the preset value of the big cast, the weighing touch screen will turn off the signal of the fast feeding, so the system enters into the process of the raw material slow feeding (close a valve), at the same time the weighing touch screen At the same time, the weighing touch screen will continue to track and read the signal from the weighing module at any time, and the touch screen will determine whether the weight of the hopper is greater than or equal to the target value of the raw material - the raw material dropout value.
If the Dosage system is greater than or equal to, the weighing touch screen will turn off the small drop signal and stop the dosage process (all valves and feeding motors will be turned off), and the dosage will be finished. If you need to cumulative dosage measurement in the same metering reaction pot, then start the second material dosage, at this time the weighing touch screen first clear the zero display output, fast feeding and slow feeding is valid, the process is the same as above. Otherwise, it starts to unload the material into the reactor.
In the dosage system start, the system PLC automatic control order to open the raw materials pneumatic valves and feeding valves, and at the same time start the feeding motor, feeding the end of the automatic closure of the feeding valves and motors, open the unloading valves and stirring motors, raw materials began to unload, the reaction kettle began to stir, stirring, the end of the system to open the reactor tank unloading valves and unloading motors, the finished product material to the finished product tank, the end of the dosage. The filling workers can start the Filling machine and operate the barrel filling process. The dosage process of the reaction kettle can also be operated manually by the operator in accordance with the process requirements by pressing the valve and motor buttons on the operating table.
Before each production, it can be set to input the formula of this dosage, and allocate the required raw material quantity proportionally (default mode can also be adopted, i.e. the formula of the last time is still used). Provide data basis for automatic dosage. At the same time as the production starts, the PLC sends the dynamic metering start signal to the weighing and metering touch screen, which then starts to collect and display the weight of each link, and adopts the fast feeding and slow feeding strategies at different weight stages, in order to take into account the need to improve efficiency and metering accuracy. When it reaches the target value, it outputs the stop measuring signal and closes the related valves and pumps by PLC control. At the same time to complete the unloading to the reactor action, metering touch screen automatically zero tare.
