AI Technical Summary
Existing graphite production kilns have shortcomings in flue gas collection and emission, dust separation and recovery, screening flexibility and transmission efficiency, making it difficult to meet environmental protection requirements and high-efficiency production needs.
It adopts a combined design of regulating air intake pipe, rotating chimney, screening device and belt drive device. The flue gas volume is adjusted by rotating blades, dust is separated by swirling flow, the screen plate gap is adjusted by planetary gear structure, and the inclined particle bin design realizes precise gas control, efficient separation and flexible screening.
It improves flue gas purification efficiency, reduces direct dust emissions, reduces resource waste and equipment failure, and lowers energy consumption and maintenance costs.
