Four-shaft crusher of urban household garbage disposal system

Abstract

The invention discloses a four-shaft crusher of an urban household garbage disposal system. The four-shaft crusher comprises four cutter shafts including the two main shearing cutter shafts and the two auxiliary shearing cutter shafts. The two main shearing cutter shafts are adjacent to each other. A main shearing cutter on each main shearing cutter shaft forms a main shearing blade. The two auxiliary shearing cutter shafts are arranged on the two sides of the two main shearing cutter shafts. Auxiliary shearing cutters on the two auxiliary shearing cutter shafts and the main shearing cutters form auxiliary shearing blades respectively. A crusher screen is arranged on the four-shaft crusher. By the adoption of the technical scheme, deep treatment is conducted on urban household garbage; harmful gas in the garbage can be decomposed, and meanwhile hazardous substances in the garbage can also be diluted; manpower and material resources are greatly saved; the garbage serves as production raw materials, organic matter and inorganic matter in the garbage are separated and utilized reasonably for producing organic fertilizer and building block materials; white pollutants are used for producing building thermal insulation materials, and harmlessness and resource recovery of the garbage are achieved.
