The basic structure and principle of high-pressure reactor    

1 batching system principle of work
The reaction kettle of batching and weighing principle block diagram of control system is as follows:
Schematic diagram
The following diagram of the reaction kettle of batching and weighing the working principle of the control system are briefly introduced in the paper:
The output voltage of the sensor signal varies with the weighing bucket material weight, the output voltage of the sensor signal to the instrument through the junction box accumulation after instrument through the A/D conversion, real-time display of the current hopper (reactor weighing) within the weight of the material, here the instrument through the serial communication way will display the weight data to the PLC, PLC the collected meter weight and touch screen (or computer) is a set weight, and control of the reaction kettle weighing action. If the configuration of the computer management system, computer can dynamically display the working state of the oil scale, real-time print weighing data, storage of historical data records, is convenient for the user to monitor the reaction kettle weighing working state and find historical data. In addition, MTCN engineers in the company office through the telephone network telephone dialing, connect the computer and user computer, engineers can be in office operation site user computer, real-time monitoring of the reaction kettle weighing state, once the user equipment problems, users only need to be connected to the telephone line the system, the company of professional engineers in the company for thousands of miles away from the user into a remote service, truly fast response.

Power indicator: after power on, the indicating lamp is bright, after the power, the indicator.
Fault alarm: when the A scale or B scale appear underload or overload, the automatic process of discharge valve or feed valve not closed in place, a storage hopper high level when the indicator light.
Feed, discharge, discharge instructions: in the feed, discharge, discharge when working, the corresponding indicator light.
Control buttons and knobs
Automatic / Manual: in "manual" mode, manual work, in the "automatic" mode, the system automatically work.
Weighing: according to the start button in the automatic mode, the system starts to work automatically.
Weighing stop: button in the automatic feeding process, system automatically stop working.
Accept the difference: in the automatic mode, the feed hopper material when over empty scale setting weight, press this button, the current scale bucket weight after clearing system to continue to work.
The final scale: button in the automatic feeding process, the end of feeding, discharging end loop.
Emergency stop: press this button in case of emergency, the system is powered down.
Feed start: in the manual mode, press this button, open the feed valve, start the manual feed work.
Feed stop: in the manual mode, press this button, stop the manual feed work.
The discharge start: in the manual mode, press this button, the discharge valve is opened to discharge, manual work.
The discharge stop: in the manual mode, press this button, stop manual discharge work.
The discharge start: in the manual mode, press this button, start manual discharging work. (in automatic mode can also operate)
The discharge stop: in the manual mode, press this button, stop manual discharging work.
A (B) scale weight - unloading plus: in manual mode, in the "plus" position, weight lifting load, under the "discharge" position, weight unloading.
