AI Technical Summary
In the current process of determining the caking properties of bituminous coal, the automation level of the drum test is insufficient, the experimental efficiency is low, and the precision and intelligent control level need to be improved. In addition, the dust pollution during the experiment is serious, which affects the working environment.
A rotary drum unit for determining the G-value of bituminous coal was designed, which integrates functions such as rotary drum testing, screening, automatic collection and disposal of coal samples, and dust removal and cleaning. The entire process is automated through PLC and edge computing system. Combined with rapping mechanism, funnel unit, screening unit and dust removal unit, it ensures that there is no residue in the coal sample and the environment is clean.
It achieves efficient, accurate, and environmentally friendly operation throughout the entire drum testing process, improving work efficiency, reducing labor costs, ensuring the accuracy and reliability of test results, and adapting to the needs of laboratories of different sizes.
