Chemical product manufacturing mainly consists of four core stages: raw material processing, chemical reaction, product separation and purification, and packaging and storage. Raw material processing lays the foundation for subsequent production and directly affects the efficiency and quality of the entire production process

When processing raw materials, physical treatments such as crushing, screening, and drying to reduce the moisture content to 0.5% are usually required. Chemical treatments such as pickling to remove rust and desulfurization and dephosphorization are also required. Finally, the raw materials are precisely measured according to the reaction equation and mixed in proportion to complete the entire raw material pretreatment, providing conditions for the subsequent chemical reaction stage

 Solution

WELLAUTO

Addressing the pain points of traditional chemical raw material processing, this solution adopts an integrated configuration of "field instrumentation + centralized control + safety protection" to build an automated system adapted to chemical raw material processing

On-site testing and execution equipment

Pre-treatment of chemical raw materials is carried out by installing humidity instruments, pressure sensors, and actuators such as electric regulating valves and automatic switching valves to achieve real-time acquisition of process parameters and automatic execution of commands

Core Control System

The main control room is equipped with a distributed control system, along with AU7 812H main unit substation control auxiliary equipment, to build a network architecture of centralized management and decentralized control, and realize the integration and unified control of data throughout the entire process

Security system

It is linked in real time with the control system, equipped with audible and visual alarms, emergency stop and emergency shut-off devices, and a gas leak monitoring and ventilation interlock system is built to comprehensively prevent safety risks, taking into account the flammable and explosive characteristics of chemical raw materials
