AI Technical Summary

Technical Problem

Existing sludge dewatering equipment is prone to damage from hard particles and impurities when treating wastewater, and the filter frames need to be cleaned frequently, which affects the dewatering efficiency.

Method used

The sludge dewatering device adopts a filter frame, stirring rod and drive mechanism. By rotating the filter frame and stirring the stirring rod, combined with the reaction of flocculant, multi-stage filtration and flocculation of sewage are achieved, reducing the entry of hard particles, reducing the risk of equipment damage, and reducing manual cleaning work through slag baffles and vibration components.

Benefits of technology

It improves wastewater filtration efficiency, reduces damage to equipment from hard particles, extends equipment lifespan, reduces the workload of manual cleaning of impurities, and enhances the overall dewatering effect.
