Novel sludge modification mixing device

Abstract

Belonging to the technical field of solid waste reduction treatment, the invention discloses a novel sludge modification mixing device, which comprises a tank body, and a driving mechanism and a mixing modification mechanism in transmission connection with the driving mechanism are mounted at the side end and inside the tank body. The mixing and modifying mechanism comprises a mixing and modifying stirring shaft as well as material returning blades, flattening blades and crushing blades which are arranged on the mixing and modifying stirring shaft, the material returning blades push sludge at the two ends of the tank body to the middle part through driving and mix the sludge, the flattening blades uniformly distribute the mixed sludge, and the crushing blades efficiently crush the agglomerated sludge; sludge and a modification accelerant can be fully mixed, and meanwhile, the sludge is prevented from being accumulated or blocked in the tank body, so that the modification effect and the operation stability of equipment are improved. The sludge fluidity and uniformity are enhanced, the modification efficiency is remarkably improved, and good preconditions are provided for subsequent dehydration treatment. The device is reasonable in structure and simple and convenient to operate, has the functions of efficient mixing, uniform material distribution and crushing, and is suitable for various sludge modification treatment scenes.
