Application Advantages of Double-pipe Steady-flow Screw Conveyor Scale in the Metering of Powdery Materials

The screw conveyor scale, often referred to as a screw weighing feeder, strictly speaking, only possesses the functions of conveying and weighing bulk materials, without automated quantitative control. However, integrating PLC control technology onto the basis of a screw conveyor scale to achieve automatic quantitative control during conveyance and dynamic weighing results in a screw weighing feeder. Typically, when mentioned, the screw conveyor scale refers to the screw weighing feeder.

In various industrial production processes, there is a high demand for accurate batching and quantitative weighing of bulk materials, often requiring comprehensive weighing and metering equipment that not only provides weight measurements but also serves as process detection for control, inspection, and communication functions, enhancing production automation and informatization levels.

Guonuo boasts extensive industry experience and case studies in dynamic metering and automation control technologies for industrial bulk materials. Specifically designed for materials requiring enclosed conveyance (especially powdery materials) in industrial production, Guonuo has manufactured the double-pipe steady-flow screw conveyor scale.

This device utilizes sealed screw pipes for material conveyance and incorporates unique steady-flow technology, with the upper layer completing material conveyance and steady flow, and the lower layer handling conveyance and weighing, while also enabling automatic quantitative control. It finds applications in numerous industries.

Recently, Guonuo has completed double-pipe steady-flow screw conveyor scale projects in chemical plants, steel mills, and other industries, all dealing with powdery materials. These projects have demonstrated unique advantages and characteristics in both on-site application and user production information management:

1. Simple Structure and Easy Installation: The screw conveyor scale features a simple structure, is easy to manufacture, and facilitates convenient installation and space-saving layout. It is also flexible in terms of displacement.

2. Durable and Reliable: Both the scale body and its components are made of industrial-grade materials, ensuring wear resistance, durability, and a long service life. They operate reliably and stably, even in harsh working environments, reducing user equipment costs.

3. Stable Material Conveyance: The two-layer screw pipes work in tandem to achieve stable conveyance of powdery materials. The upper screw pipe ensures uniform and constant material flow into the lower screw pipe, guaranteeing even and stable material passage through the weighing area, thereby maintaining production stability and improving metering accuracy.

4. Dust Prevention and Material Characteristics Preservation: Many powdery materials in industrial production are fluid, have low density, and are prone to dust generation. The steady-flow technology prevents material surges, while the sealed screw pipes prevent on-site dust, preserving material characteristics and maintaining a clean production environment without dust, spillage, or pollution.

5. Operability and Maintainability: The scale features a user-friendly, human-machine dialogue interface with guided menu operations, making it easy to use. Basic maintenance and inspections are sufficient for the scale itself. The instrument also includes calibration, verification, self-monitoring, self-diagnosis, and automatic alarm functions to promptly detect equipment faults.

6. PLC Automation Control Integration: It can be integrated with PLC automation control technology to achieve quantitative control. When configured with a batching system, it forms an automated bulk material batching system.

7. Data Sharing and Remote Monitoring: The scale's instrument is equipped with information interfaces, facilitating connection to enterprise local area networks for data sharing. Leaders can remotely monitor production status (including real-time equipment operation and weighing batching data), query historical data, and automatically generate production reports, achieving production process automation and production management informatization.

Lastly, it is worth mentioning that Guonuo provides professional and comprehensive pre-sales and after-sales services for the double-pipe steady-flow screw conveyor scale. Pre-sales, it offers professional, customized solutions based on user site conditions to ensure equipment meets on-site requirements. Post-sales, technical engineers are dispatched for on-site guidance, debugging, and installation to ensure correct and stable operation of the screw conveyor scale.
