The 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.
020-34563445The Weighing system of vacuum mixer is a mechatronic system integrating automatic control technology, metering technology and computer management technology. It has the advantages of digital display of weight value, dynamic display of process picture, formula modification and management, fast batching speed and high control accuracy. It adopts the complete screen of the upper computer for batching, and has the functions of automatic storage of batching data, query of batching process list, statistics and printing of class, day, month and year reports. Adopt open control mode, strong compatibility and open database. Factory-level LAN can be accessed through Ethernet to realize the integration of management and control.
Weighing Feeder can meet the requirements of batching control accuracy and reduce the cost as much as possible through the proportion of raw materials. According to the different materials of each batch, the optimized calculation table is input into the database by using WINCC's visual man-machine interface, and the calculation data is read and displayed in the interface, and the database application program is created visually, which makes the application of the database more convenient and flexible, and supports the application of the network environment.
Weighing dosing machine installs a weighing module at the bottom of the silo, and ensures the normal operation of the whole system through precise control of 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.
Description of main functions of feeding system
1. The weighing control system realizes the functions of manual operation and automatic control of batching.
2. The beautiful and practical dynamic simulation of the production process of the system can display the real-time working state, target weight, actual weight and error value of each material.
3. Store the recipe preset, and call, modify, delete and query the recipe at any time.
4. In the process of batching, there is an automatic alarm function for material shortage, and you can manually change the number of the tank warehouse with the same material online.
5. It has the functions of operator authority management, site management and networked remote service.
6. The industrial computer is used as the monitoring system of the upper computer, and WINCC is used to monitor the configuration, so as to ensure the stability, reliability and long-term performance of the system.
7. The system adopts man-machine dialogue mode, which is simple to operate and maintain.
8. Remote management can be realized, and the computer in the control room can be networked with the computer in the general manager's office. The general manager can check the production situation and production report in real time.
9. The frequency conversion reaction tank is used to control the blanking, so as to improve the batching accuracy, thus improving the product quality and stability.
