Spiral batching machine adopts advanced programmable controller (PLC), there are three kinds of control methods: automatic control, remote operation and local manual control, and automatic control is adopted under normal circumstances. The control system can realize automation of collecting operation data and fault signals, automatic analysis of operation data and fault judgment, and realize classification alarm for faults in the system.

Weighing and batching machine consists of big storage bin, bag filter, induced draft fan, balance valve, screw feeding device, storage hopper, etc. Powder sent by conveying system is sent to different big storage bins for storage according to models. When conveying the powder, the induced draft fan will automatically open and control the powder flying through the bag filter, the balance valve will automatically open to balance the pressure in the big storage bin, the screw feeding device at the bottom of the big storage bin will send the powder to the storage hopper to wait for further conveying to the weighing system, the balance valve will be automatically closed after the conveying is finished.

Weighing dosing machine supports Microsoft's various networks, with simple networking and database functions. WINCC not only has its own database, but also supports SQL language, which can be easily connected with other databases. WINCC provides various powerful functions, which can meet various special requirements of users in operation, display and recording through configuration. Through transformation, the system can upload industrial process parameters, cost parameters, major and minor parameters, etc. to the management platform and auxiliary decision-making platform in real time through the information bus.

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 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.

Explosion-proof batching machine is a very important process in the chemical production process of electronic scales, mainly to complete the weighing and proportioning of the main material and various ingredients. After the batching of the former system will be formed by the base powder through the spiral scale and conveyor sent to the premixer and the raw materials mixed by the conveyor sent to the finished product warehouse. The post-batching realizes the measurement of the flow of the conveyed materials.
