Analysis on the Status Quo of Key Technologies of Belt Conveyors
Author :
In terms of efficient soft start and power balance technology, permanent magnet variable frequency synchronous direct drive systems have been widely used in coal mine belt conveyors in recent years.
1) In terms of efficient soft start and power balance technology, permanent magnet variable frequency synchronous direct drive systems have been widely used in coal mine belt conveyors in recent years.
2) Some progress has been made in the research on the dynamic behavior of conveyor belts in my country. Scientific research units such as Northeastern University and Shanghai Coal Research Institute have developed dynamic analysis software for belt conveyors, and have achieved comparative results on some long-distance and large-capacity belt conveyors. good application effect.
3) The stability and reliability of the operation of the belt conveyor transportation system not only depends on the operation stability and reliability of each belt conveyor, but also depends on whether the design of the transfer point is reasonable.
4) With the development of video analysis technology and artificial intelligence, the intelligent perception technology of belt conveyors has also developed rapidly. Through video image analysis technology, Ningxia Guangtianxia Electronics Co., Ltd. and Shanghai Coal Academy of Sciences have developed equipment such as real-time coal quantity detection and foreign object identification for belt conveyors, which can be used as the basis for intelligent speed regulation of belt conveyors, and at the same time identify the conveyor belt in time. Bring foreign objects to avoid personal and property damage.
5) The intelligent control technology of the belt conveyor can realize the energy-saving, efficient and reliable operation of the belt conveyor. Through start-stop adaptive control, coal volume adaptive speed regulation, multi-level coordinated control, coal flow balancing technology, etc., the carrying efficiency of belt conveyors is improved, the output of each drive motor is balanced, and energy saving and emission reduction are achieved, reducing losses and extending The economic benefits of equipment life, reduce frequent speed regulation, coal spillage, coal sprinkling and heavy load, and meet the requirements of modern coal mining industry.
7) The intelligent operation and maintenance management platform supporting the intelligent operation of the belt conveyor is the short board of the existing products on the market. Traditional automatic control collects equipment operation, fault information and realizes control and monitoring functions, lacks equipment management functions, and does not realize data sharing, deep integration and utilization.
