The weighing and feeding system adopts the new WINXP system platform, which is faster and more stable. The real-time dynamic production screen shows the production process, and the operation is intuitive and clear; the powerful report function can record and store a large amount of various types of data and tabulate and print, and it automatically prints the dosage report after the completion of each production, and provides the information of date, time, report number, and the actual consumption of each kind of material; the report extraction adopts the PC manual query method. The report is extracted manually by PC, and the end-of-production report is stored in the computer, which can be read indefinitely to ensure the correctness and completeness of the production report. Simple operation, the system has three production modes: manual, semi-automatic and fully automatic.

Automatic feeding system is a comprehensive automatic system that integrates computer production process control and data management such as weighing and feeding, formula control and discharging. It displays parameters such as temperature, pressure, liquid level, weight and volume in real time, and makes corresponding ultra-high or ultra-low alarm warning for the storage tank according to the conditions. It integrates various control functions, such as pump and valve control and alarm system. It can carry out warehouse management, inventory management, procurement management, cost management and so on.

Feeding system combined with industrial control technology and Internet of Things technology professionally developed a set of flexible and variable production control system software, the production process of the various control points integrated into a control software, the customer only in the central control room can control the entire factory production process. It really realizes a highly integrated, automated and unmanned efficient workshop. Central control data acquisition control system: comprehensive observation, centralized management. With PLC/DCS as the core control, the computer system is responsible for formula calculation, personnel management, data collection, query and printing. The central control computer monitors and controls the on-site production situation, reflecting the operation of each production unit in real time.

The feeding system is an indispensable equipment for the mixing tank, which realizes the process of automatic conveying, storage, weighing and feeding. According to the physical properties of raw materials, all kinds of materials are sucked into the mixing tank by negative pressure once or many times in order, measured and temporarily stored, waiting for the mixing tank feeding signal, and then start the next batch of sub-metering action after completion.

The automatic feeding system adopts DCS control system, the pneumatic, stopping and running of the whole system are controlled and monitored in the control room; the whole equipment is equipped with fault detection system, if the equipment in the rear section fails, the equipment in the front section stops by itself and displays the location of the fault point and the reason, and shows the system running status with alarm light; the control mode adopts three-level control mode: upper machine position → PLC → dosage instrument. The control interface is simple and clear, with animation displaying the dosage process and dosage data, which is clear and eye-catching; the personnel in the control room contact with the field personnel through the walkie-talkie.

Weighing mixer for additives and pre-mixing unit, PLC as the main control of the unit, weighing module to collect the weight of the material in the mixer and should have the position (prompted when the material is lost). Limit switch, when the lifting action reaches the position, it should be signaled at the appropriate position. Analog output signal, 4-20mA to 4 valve switches to control the opening, with S type tension to collect the material position and close the valve when the weight reaches the required dosage weight. Has a communication circuit module whose function is to communicate with the console. The communication data is bi-directional and is required to receive information from the console about the specific gravity of the material and the weight distribution of each material mixer.

By using the upper computer monitoring system, the weighing mixer can complete the configuration, debugging, online correction of detection parameters and setting of control parameters, the weighing transmitter is used to detect the change of material level in the material batching tank, and the volume and weight of the amount of material in and out is obtained by using the cross-sectional area of the measuring tank.

The automatic feeding system accomplishes the tasks of parameter control, sequence control, position control, speed control, tape control, temperature and shape control. It mainly accomplishes the tasks of initial data input, material tracking, process parameter setting calculation, data recording and reporting, man-machine dialogue processing, data communication, simulation modeling, historical data processing, application system startup, event monitoring, etc. The process control automation level computer system reserves the communication interface with continuous casting and computer system.

Weighing mixer from the silo into the electric arc valve, and then sent by the screw feeder into the electronic scale to measure the size of the flow, and according to the actual need for electronic scales to adjust the speed of the screw feeder, so as to achieve normal feeding. Through the measurement of the electronic scale into the spiral pneumatic conveying pump feed box, and through the feeding mechanism forward, into the mixing bin and by the fan outlet air gasification, and sent to the conveying pipeline.
