The Level weighing mixer adopts an all-Chinese interface, which displays the working state of ingredients graphically and dynamically, and displays the weight of materials in the measuring hopper digitally, which is suitable for the operating habits and knowledge level of operators. Almost all the operation buttons can be clicked on the screen by the mouse, which improves the production efficiency and reduces the labor intensity of workers. Through the Ethernet in the production site, the batching computer in the production site can be networked with the office computer, and the production output statistics and raw material consumption assessment can be paperless. Data can be saved indefinitely.

Powder dosing machine is based on many parameters such as raw material composition, auxiliary material composition, etc., and the specific production process design is calculated by combining the data needed for actual production calculation. The system software includes subsystems such as raw material composition input and ingredient calculation. The weighing system is designed and realized by using ORACLE database system and c# language, and it has been successfully applied to the batching site with the guarantee of calculation accuracy and beautiful and convenient interface.

The weighing loading machine is mainly controlled by PLC for the electrical control of the system, the display of the weighing instrument and the control of the weighing module. It can realize the control of the frequency converter of the separator, remote start and stop of the main motor, control of the size and speed of the tensioning station screw, display of the thrust and temperature of the main motor, and remote start and stop of the batching machine, etc. The 4~20mA analog signals collected on site are converted into weighing signals through the analog input module of the PLC. The PLC program compares the instantaneous value of the detected screw with the set value in real time internally, and controls the start and stop of the screw conveyor by the digital output template.

The feeding system adopts Siemens PLC to control the automatic operation of all its interlocking devices (start-stop, interlocking, position switching and other operations), and the upper computer is programmed by Siemens WINCC configuration software. The whole configuration operation screen is embedded into the whole weighing system, and the operation of equipment start-stop operation, operation display, fault inquiry record and maintenance are carried out. The system has the characteristics of friendly interface, concise operation and reliable operation.

The materials in the dosing machine control bin are weighed and transported to the rail moving tank car through the belt weighing device, and then the mineral materials are transported to the bottom-laying bin on the top of the furnace seat by the moving tank car. The whole process can be controlled manually or automatically by PLC. The movement of electrical equipment (walking control and electro-hydraulic push rod) on the mobile tank car is given control instructions by the ground part through wireless data transmission equipment, which greatly improves the advanced and simple batching system.

The Storage automatic dosing machine is usually composed of a weighing module, a weighing body, a discharging mechanism, a feeding mechanism and a control system. The weighing module cooperates with the weighing transmitter, PLC and touch screen, and measures the weight through the weighing module under the scale frame to ensure the quality of raw materials on the silo. When the system is running, the weight data and speed signal received by the computer are converted into accumulated value and instantaneous flow after operation, and the data are transmitted to the work control machine, and the analog current signal is transmitted to the frequency conversion controller, and the frequency conversion machine properly sorts out the current, changes the rotation speed of the superior feeder, and then completes the calculation and configuration of raw materials.

The measuring dosing machine adopts the pulse width modulation control method based on the incremental PID algorithm. The adjustment signal obtained by the incremental mode is output to the D/A holding circuit through the PB1 port. The D/A holding circuit converts the duty cycle of the PWM square wave into the corresponding 0-5V voltage value, and outputs it after photoelectric isolation.

The Concentrated automatic dosing machine calculates the formula according to the detection data, and inputs it into the computer system through the man-machine interface or computer network. 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 Ingredients weighing system adopts automatic/manual proportioning control, and multiple materials are mixed at the same time, with fast batching speed. The feeding sequence can be adjusted at will, formula calculation and manual correction. The graphical interface shows the working conditions of batching, and the operation is intuitive. Realize the recording, printing and report generation of proportioning data. Automatic and manual control of arch breaking. Intelligent diagnosis of sensor wiring fault, accurate positioning of faulty sensor and faulty wiring, and automatic tare tracking. Remote data browsing and printing.
