Description

Technical Field

[0001] This utility model relates to a coke transport status monitoring and alarm device for high-risk coking areas. Background Technology

[0002] As a core pillar of the modern heavy industry system, the coking industry's strategic value and technological complexity deserve in-depth explanation. Essentially, this technology involves a high-temperature dry distillation process (900-1100℃) to deeply thermally convert carbonaceous raw materials such as coal and petroleum coke, producing three basic products: coke, coal gas, and coal tar. Metallurgical coke, as a key reducing agent and supporting framework in blast furnace ironmaking, directly determines steel production capacity and quality. Coal tar, after further processing, can yield over 300 aromatic compounds such as anthracene, phenanthrene, and carbazole, which are important raw materials for synthetic dyes, pharmaceuticals, and carbon materials. City gas, produced after the purification of raw coal gas, constitutes an important part of the energy structure. This multi-product characteristic makes the coking industry a crucial link between energy conversion and materials manufacturing.

[0003] In the coking production chain, the stable operation of the coal preparation system is crucial. Modern coke ovens can process tens of thousands of tons of coal per day, and their coal blending conveyor belts often face multiple challenges: uneven coal particle size distribution leading to off-center loading, fatigue damage accumulation at belt joints, and aging of the conveyor belt cover rubber caused by dust erosion. These factors can all cause sudden failures such as belt misalignment and longitudinal tearing. Statistics show that unplanned downtime caused by transmission system failures accounts for 37%, and the average time to handle a single accident is 4.8 hours. This not only causes direct economic losses but may also trigger secondary disasters such as gas leaks and fires.

[0004] To address the monitoring challenges in high-risk operating environments, the industry has developed a three-dimensional solution: laser displacement sensors are deployed at the head and tail of the conveyor belt to collect real-time spatial coordinates of the belt edges, enabling early warning of belt misalignment through edge computing modules; electromagnetic induction coils are installed under the return conveyor to detect early signs of tearing, such as protruding metal wires, using eddy current effects; and infrared thermal imagers are configured at key nodes to monitor abnormal temperature rises caused by idler roller jamming. Coking is a high-risk process, and this monitoring method requires operators to locate faults from a safe distance; workers should be kept as far away from the site as possible, making real-time monitoring of the coking coal conveying system difficult.
