AI Technical Summary
Traditional diatomite screening machines suffer from low efficiency and low precision, especially during continuous feeding when material accumulates and particles of different sizes are mixed, leading to reduced screening efficiency.
A screening machine with an intermittent feeding mechanism was designed. The opening and closing of the feed pipe is controlled by a motor-driven half gear and linkage gear system to achieve intermittent feeding of raw materials and avoid accumulation and mixing.
This improves the efficiency and accuracy of the screening machine, ensuring the full separation of diatomaceous earth particles of different sizes, preventing fine particles from being trapped, and enhancing the screening effect.
