Technical Field

The invention relates to the field of organic garbage anaerobic pretreatment equipment, in particular to a high-solid-content or high-viscosity organic garbage slurry conveying device.

Background

The anaerobic biological treatment technology is a high-efficiency comprehensive treatment and resource technology which decomposes, metabolizes and digests organic matters in the slurry through anaerobic bacteria under an anaerobic state, so that the content of the organic matters in the sewage is greatly reduced, and simultaneously, the methane is generated. The slurry required by the organic garbage anaerobic biogas production project does not belong to high-solid-content/high-viscosity materials (solid content is 15-30%), and a bolt conveyor is adopted in the traditional conveying mode. The slurry with solid content not more than 20% is usually prepared by screw pump in sewage treatment industry. The conveying height of screw conveying equipment in the actual operation process is no more than 4m, the conveying distance of the single equipment is no more than 10m, and the particle size of solid particles in the conveying material of a screw pump is no more than 5 mm. Slurry before slurry mixing is conveyed to subsequent equipment by using a screw conveyer, and materials are lifted to a required height by using a plurality of sets of equipment, so that the equipment investment cost is high, the occupied area of a treatment workshop is large, and the energy consumption in the operation process is high. Slurry is easy to spill on the bearing seat of the spiral conveying equipment, so that the operating environment is stink and sewage is difficult to control. In actual operation, the structural impurities in the slurry with the solid content not higher than 20% are complex in properties, and the impurities with the particle size not higher than 5mm often appear, so that a cavity of a screw pump is blocked, and a treatment system is difficult to continuously operate.
