Advantages of Explosion-Proof Electronic Belt Scales in Coal Washing Plants

Industrial automation and intelligence are among the production management goals pursued by modern industrial manufacturing enterprises, aiming to utilize various automated equipment to complete operational activities without direct human intervention.

Industrial automated measurement is a crucial aspect of this, particularly for the measurement of bulk loose materials such as coal, building materials, and cement, where automated measurement devices are almost essential.

The electronic belt scale is a type of weighing instrument specifically designed for the automated measurement of bulk industrial loose materials, capable of quickly, efficiently, and accurately completing measurements without human intervention.

However, in certain special industries and settings, such as the coal industry, the challenges extend beyond just large transportation volumes. The application environment can be harsh, with the presence of flammable and explosive gases in coal mine shafts. Additionally, production sites are often separated from management by long distances, making management difficult.

Ordinary industrial electronic belt scales are not suitable for such conditions. To address safety, measurement management, and other issues, explosion-proof electronic belt scales have been developed.

These scales not only possess the efficient, accurate measurement and data provision capabilities of ordinary industrial electronic belt scales but also offer the crucial advantage of being safely and reliably applicable in various harsh working environments, including flammable and explosive conditions in coal mine shafts.

The coal industry encompasses operations such as coal mining and coal washing, all of which rely on explosion-proof electronic belt scales. For automatic measurement operations in coal washing plants, which may occur either underground or above ground, the choice to use explosion-proof electronic belt scales depends on the installation location.

Recently, Guonuo Technology has completed the installation and commissioning of explosion-proof electronic belt scale projects in multiple coal washing plants, utilizing explosion-proof belt scales both underground and above ground.

The decision to use explosion-proof belt scales for above-ground operations, in addition to environmental considerations, is also based on their overall performance.

Firstly, they ensure application safety. The use of explosion-proof electronic belt scales in coal washing plant operations, particularly underground, is undeniable. These scales incorporate explosion-proof measures in their instrumentation, sensors, data substations, and other electrical components, such as the use of explosion-proof enclosures and intrinsically safe circuits, enabling safe operation in environments containing combustible gas mixtures, like coal mine shafts. Even above-ground operations at coal washing plants, such as those at mine entrances and exits, necessitate the use of explosion-proof belt scales.

Secondly, they guarantee application accuracy. Weighing and measurement operations in coal washing plants are crucial for production monitoring and coal quantity accounting, thus requiring high measurement accuracy from electronic belt scales.

Explosion-proof electronic belt scales are equipped with digital weighing sensors that offer stronger resistance to adverse factors in harsh working environments, along with features like linear compensation and temperature compensation to fully ensure the accuracy of coal weight detection.

Dual-wheel DC pulse speed measurement sensors accurately detect belt speed, while the scale frame structure can be selected based on conveyor conditions, such as matrix-type high-precision belt scale structures. In summary, explosion-proof electronic belt scales ensure measurement accuracy while maintaining safety and better adapting to working conditions.

Additionally, they provide application stability. Explosion-proof electronic belt scales are constructed with industrial-grade components and high manufacturing standards, featuring high protection levels and various anti-interference measures.

The instrumentation also includes functions like online zeroing and calibration, enabling them to maintain their original accuracy over long-term operation. Without this, the accuracy of the belt scale would not be sustainable, failing to meet the precision requirements of coal washing plants.

Moreover, they ensure application manageability. In addition to their measurement functions, explosion-proof electronic belt scales can be integrated into the coal washing plant's information network for data sharing.

Equipped with upper computer software systems, management departments can remotely monitor the real-time operation and measurement data of the belt scales, query historical data and analysis reports, or set operations, addressing the issue of separation between measurement sites and management.

Lastly, they offer application operability. Despite being equipped with explosion-proof enclosures, explosion-proof electronic belt scales feature quick-opening door structures, remote calibration capabilities, and one-click calibration functions, facilitating calibration and maintenance work. The instrumentation is simple and easy to operate, enhancing operability.

In conclusion, explosion-proof electronic belt scales offer high safety coefficients, strong stability, and high accuracy, meeting the demands of harsh working environments in coal washing plants. They contribute to strengthening production monitoring and management in coal washing plants, significantly enhancing their automation and informatization levels.
