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.
020-34563445The discrete vacuum mixer Weighing system is a mechatronic system integrating automatic control technology, measurement technology and computer management technology. It features digital display of weight values, dynamic display of process images, modification and management of formulas, fast batching speed, and high control accuracy. The upper computer adopts a complete screen for batching, featuring automatic storage of batching data, query of batching process lists, statistics and printing of shift, daily, monthly and annual reports, etc. It adopts an open control mode, has strong compatibility and an open database. Factory-level local area networks can be accessed via Ethernet to achieve integrated management and control.
The weighing Feeder achieves the requirements of batching control accuracy and minimizes costs by proportioning the usage of each raw material. According to the differences of each batch of materials, it can be changed arbitrarily. The optimized calculation table is input into the database. By using the WINCC visual human-machine interface, the calculation data is read and displayed on the interface. The database application program is visually created, making the application of the database more convenient and flexible. At the same time, it supports applications in network environments.
The weighing and batching machine is equipped with a weighing module at the bottom of the silo. Through the precise control of the electrical program, the normal operation of the entire system is ensured. The control objects in the positive pressure pulse material acid pneumatic conveying process are the exhaust valve, feed valve, discharge valve, pulse air knife valve and inlet air valve in the silo. The control mode is based on a Siemens programmable controller as the control source. Through the operation of the Proface touch screen, contactors and intermediate relays are used to control each solenoid valve and motor, which is convenient for debugging and maintenance.
Main function description of the feeding system
The weighing control system realizes the manual operation and automatic control functions of batching.
2. Conduct an aesthetically pleasing and practical dynamic simulation of the system's production process, which can display the real-time working status, target weight, actual weight and error value of each material.
3. Store formula presets and you can call up, modify, delete and query formulas at any time.
4. During the batching process, there is an automatic alarm function for material shortage, and the tank warehouse number can be manually changed online with the same material.
5. It has the functions of operator permission management, on-site management and networked remote service.
6. An industrial control computer is adopted as the upper computer monitoring system, and WINCC monitoring configuration is used to ensure the stability, reliability and long-term performance of the system.
7. The system adopts a human-computer dialogue mode, making operation and maintenance simple.
8. Remote management can be achieved, and the computer in the control room can be connected to the computer in the general manager's office. The general manager can view the production situation and production reports in real time.
9. The adoption of variable frequency reaction tanks for material discharge control enhances the accuracy of batching, thereby improving product quality and stability.
