The Reunite mixer is automatically or semi-automatically completing the proportioning, weighing, feeding and distributing of raw materials at each time until the required weighing/feeding times of each batch are completed. At this point, PLC has completed a series of operations and controls. Such as the following target value calculation, raw material target value calculation, parameter automatic correction, etc. The main screen of each raw material and its parameter setting window have relevant parameters displayed, which can be used as control reference by the operator.

The constant pressure Feedback mixer controls the metering equipment to weigh in turn until the specified n times of weighing are finished, and the CRT returns to the display state when it is 0 times. When weighing a certain time, if any equipment or control point of the feeder or feeding system stops weighing, PLC can keep the memory of the time and continue weighing according to the memory of the time. DCS+PLC+ local manual control mode is adopted. The feeding process is completed by PLC, and its temperature and pressure are monitored by DCS system.

The Discrete vacuum mixer runs Siemens WINCC monitoring software through the computer, communicates with the two communication ports of the programmable controller through their respective communication ports, and backs up each other. It can dynamically display the process flow of the entire production process, display the operation, failure and alarm status of each equipment, and display process parameters such as temperature, pressure, etc. And can set such as alarm value, timing parameters, weighing instrument parameters.

The Positive Pressure weighing feeder records the weight data of various materials, which are stored in the database, and produces reports such as class report, daily report and monthly report according to these data. The system also monitors the high mixing temperature and silo temperature in real time, and has real-time curve tracking to monitor the real-time temperature of materials and silos and historical curve to query the historical temperature. The programmable controller not only completes the logic control of the whole production line, but also communicates with weighing instruments and temperature control instruments. Besides reading the weight data every time, it can also set the working parameters of each instrument to realize remote monitoring.

The weighing vacuum feeder adopts the Siemens MMI software WINCC. The system is mainly divided into four screens: process flow screen, parameter setting, centralized control, trend curve and report. Above the clock, there are numerical displays of the total pressure of the gas path and the temperature of the cooling water. In addition, in the process flow, there are main material feeding unit, batching unit, vacuum feeding unit, mixing unit, finished material unit, pulse valve parameter setting, weighing instrument parameter setting, temperature alarm limit setting, motor current display, valve summary control, and temperature alarm curve graph.

The weighing module, pressure transmitter, level gauge, position switch on the pneumatic valve, air source pressure gauge and other components in the ton bag automatic mixer are used to detect and monitor the working conditions. For multi-bin conveying, the three-way valve can be controlled by the touch screen to make bin selection judgments. When the multi-bin pump conveys a single bin, to prevent material backflow, a shut-off valve needs to be installed above the receiving bin.

The Weighing fully automatic mixer adopts an industrial computer with high protection level as the main control computer of the system, and a special filter screen is used in the computer ventilation and heat dissipation system, which can be cleaned or replaced regularly and can effectively remove the influence of dust in the air on the equipment. The weighing system is input into the computer system through the man-machine interface or computer network, and the computer control system automatically calculates the supply ratio of each raw material according to the detection data and the process formula, and then the PLC control system synthesizes the supply speed of each raw material supply system to accurately and continuously complete the raw material ratio according to the process sequence.

The Positive pressure weighing mixer achieves the requirement of batcher control precision and reduces the cost as much as possible through the dosage ratio of each raw material. According to the difference of each batch of materials and arbitrary change, optimize the calculation table input database using the development of visual man-machine interface, read the calculation data and display in the interface, visually create the database application program, make the application of the database more convenient and flexible, while supporting the application of network environment.

The Fan weighing mixer installs a module at the bottom of the silo, and ensures the normal operation of the whole system through the precise control of the electrical program. The control objects in the pneumatic conveying of positive pressure pulse material and acid are the exhaust valve, feed valve, discharge valve, pulse gas knife valve and inlet valve in the silo. The control mode is controlled by Siemens programmable controller, and the solenoid valves and motors are controlled by the operation of Proface touch screen, contactors and intermediate relays, which is convenient for debugging and maintenance.
