The uniquely designed triangular rotor self-cleaning filter principle is used to realize an environmentally friendly, vibration-free, and noise-free solid-liquid separation device. feature: 　　 1. No blockage, no need to backwash the gap. The continuous rotation of the triangular rotor between the gaps enables solid-liquid separation and self-cleaning at the same time. 　　2. Stable processing capacity, through self-cleaning of the filter slits, it will not reduce the processing capacity due to clogging like other filter types of dehydrators. 　　3. Powerful conveying ability, through the rotation of the triangular rotor, the separated solids are automatically conveyed. 　　4. Easy to maintain, due to the simple structure, maintenance is also relatively easy.
