The Pulse weighing system starts the industrial computer to send a feeding signal to the PLC, the PLC controls the frequency converter for fast feeding, the weighing sensor sends the weight signal through the transmitter to the PLC, the PLC converts the analog signal into a digital signal, the signal is normalized and quickly added to a certain amount, the PLC controls the frequency converter for slow adding, when the advance amount is reached, the feeding is stopped.
020-34563445The pulse Weighing system, in response to the current situation where the weighing accuracy of small materials is not high, the efficiency is low, the maintenance volume is large, and the requirements for materials are strict, the small material automatic Batching system has the characteristics of strong adaptability, high efficiency, high weighing accuracy, small floor space, and not strict requirements for material properties. Multiple feeding methods such as star-shaped double helical are adopted to ensure the speed and accuracy of automatic weighing. All silos are equipped with stirring devices to guarantee good fluidity of the materials. The feeding of the main unit adopts a novel push-sweeping method to ensure that the weighed materials can be fully fed into the main unit. This method does not require breaking the arch, requires no maintenance, and is economical and convenient.
The weighing and batching system 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 calculation table is optimized and input into the database. A visual human-machine interface is developed using VisualBasic to read the calculation data and display it on the interface. Database application programs are created visually, making the application of the database more convenient and flexible, and it also supports applications in network environments.
The weighing feeding system is equipped with modules at the bottom of the silo and is precisely controlled by electrical programs to ensure the normal operation of the entire system. 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.
