Bucket turbine coal blending angle change electronic belt weigher research project passed appraisal

[China Instrument Network Instrument R&D] A few days ago, the “Study on Variable-angle Electronic Belt Scale for Coal Blending of Bucket Wheel Machines” led by the Zhejiang Metrology Institute passed the scientific and technological achievements appraisal, and the overall technical level of the results was at the leading level in China.

Electronic belt weigher is a kind of metering equipment that carries out continuous automatic weighing of materials during the process of conveying material on the belt conveyor. It has been widely used in industrial batching and metering assessment of iron and steel, mining, wharf and other industrial bulks. Its characteristics are called The volume process is continuous and automatic, and usually the operator can complete the weighing operation without the intervention of the operator. Installing the electronic belt weigher on the stacker reclaimer can improve the accuracy of coal blending and ensure the quality of coke is stable.

The advantages of electronic belt weighers are low cost and simple installation. There is no need to make too much changes to the original equipment. The disadvantage is that the measurement accuracy is not high due to the influence of the conveyor belt.

Therefore, the Zhejiang Provincial Institute of Metrology led a research project to develop a variable-angle electronic belt weigher system that can greatly improve the measurement accuracy of the electronic belt weigher. At present, the project has been successfully applied to the R1 bucket wheeler of Zhejiang Zengeng Port Operation and Management Co., Ltd. After more than one year of operation, the data is stable and reliable, which improves the measurement accuracy and operational reliability of the bucket conveyor variable-angle electronic belt scale, solves the measurement error introduced by the change in the tilt angle of the bucket wheel crane, and reduces the work strength of the maintenance personnel. , to promote enterprises to reduce costs and improve efficiency.
