Composition and Functional Characteristics of Automated Weighing and Batching Control System for Bulk Materials

The automated weighing and batching control system for bulk materials is an automation system for real-time monitoring and management of industrial processes that involves weighing bulk materials such as blocks, granules, and powders, and controlling their feeding and mixing according to specific recipes. It is widely applicable in industries such as metallurgy, building materials, chemicals, and feed production.

The automated weighing and batching control system mainly consists of the following parts:

(1) Conveying Part: It adopts screw feeders or belt feeders for material conveyance, with the method selected based on the material's characteristics, responsible for delivering materials to designated locations.

(2) Weighing Part: It comprises weighing sensors, speed sensors, etc., which work with weighing instruments to measure materials and detect errors.

(3) Control Part: It primarily includes weighing instruments, an industrial PC (IPC), a programmable logic controller (PLC), and other control devices. The IPC, equipped with a PLC, digital I/O modules, manual/automatic control switch, manual control buttons, and indicators, is housed in an integrated control cabinet for centralized management and convenient operation.

(4) Software Part: It is designed according to the basic and actual requirements of the batching system. Overall, it allows for viewing real-time and historical production data and reports, setting recipes, equipment, and other related parameters, and remote control and monitoring.

The basic functional characteristics of the automated weighing and batching control system are as follows:

(1) The weighing module in the batching system features automatic zero tracking and adjustable zero control.

(2) It has functions for physical calibration and verification, as well as chain code calibration and verification.

(3) The system features online self-monitoring, self-diagnosis, and self-alarm functions, with real-time self-checking and automatic alarm through sound and light in case of faults.

(4) It has power-off protection, ensuring that accumulated data, parameters, and time and date within the instrument are not lost during power outages. Upon power restoration, it resumes operation based on the previous data.

(5) The system offers communication capabilities, with the feeding equipment and instruments equipped with multiple communication interfaces for easy networking and data sharing.

(6) It provides input/output interfaces, including digital I/O interfaces, for connection to computer management networks, enabling quick and convenient transmission of measurement data to various workstations online for data sharing.

(7) The system features menu-guided operation, which is simple and easy to learn, with no special technical requirements for operators.

(8) It uses digital weighing sensors with strong anti-interference ability and high weighing accuracy.

(9) If equipped with a belt feeder, the system can be configured with automatic tensioning and anti-deviation devices to maintain stability.

(10) An automatic cleaning device can be configured to prevent material clogging and reduce maintenance workload.

(11) The system adopts a decentralized control and centralized management mode through control cabinets, facilitating management and operation.

(12) Parameters can be modified according to recipe changes, allowing the system to batch according to new recipes with flexibility and convenience.

(13) Materials are accurately weighed and measured before controlled feeding, ensuring precise control and improved batching quality.

(14) The system exhibits overall stability and durability, ensuring continuous and stable production and maintaining production schedules.

(15) The system is highly automated and informatized, completing batching automatically and improving operational efficiency.

(16) It features reliable data protection functions, safeguarding the accuracy and completeness of production data for convenient production management.
