Rake type pulverizing hot air stirring sludge drying device

Abstract

The invention discloses a rake type pulverizing hot air stirring sludge drying device. The rake type pulverizing hot air stirring sludge drying device is composed of a speed changing motor, a feedinggroove, a spiral material guiding and feeding shaft, a machine body, grid section wing plate scattering teeth, a stirring shaft, an air outlet, a bearing fixing sleeve, a discharging port, machine legs, a hot air inlet pipe, a speed reducer, a supporting platform and a stirring motor. The hot air inlet pipe is adopted for drying sludge biological organic fertilizer and biological solid fuel entering the machine body, the stirring shaft with the grid section wing plate scattering teeth arranged at equal intervals is used for stirring and pulverizing the sludge biological organic fertilizer andthe biological solid fuel entering the machine body, and the defects that feeding is caked, pulverizing is difficult and the drying effect in blocks is not good are overcome. The beneficial effects that the drying yield is high, the treating capability is high, the material body pulverizing, colliding and scattering effects are good, and the processing cost is low are achieved; and the rake type pulverizing hot air stirring sludge drying device is ideal equipment for sludge biological organic fertilizer and biological solid fuel drying production.

Description

technical field [0001] The invention relates to the technical field of drying machines, in particular to a rake-type crushing hot-air stirring sludge drying device. Background technique [0002] Sludge bio-organic fertilizer and bio-solid fuel are one of the biomass resources from animals and plants. Using sludge as raw material, it is mixed with organic waste such as traditional Chinese medicine dregs, livestock and poultry manure, and agricultural straw. Bacteria decomposing and fermenting it multiple times to kill pathogenic bacteria and parasites in the sludge, eliminate peculiar smell, and produce high-efficiency organic fertilizer and bio-solid fuel through dehydration, granulation and drying processes. However, the traditional drying method has the disadvantages of separate granulation and drying of sludge bio-organic fertilizer and bio-solid fuel. During drying, there are defects such as agglomeration, not easy to break, and poor drying effect inside the block, which...

Problems solved by technology

However, the traditional drying method has the disadvantages of separate granulation and drying of sludge bio-organic fertilizer and bio-solid fuel. During drying, there are defects such as agglomeration, not easy to break, and poor drying effect inside the block, which cannot improve the quality of bio-organic fertilizer. and the production of biosolid fuels, seriously affecting the production efficiency and production volume of enterprises
