Abstract

The invention relates to a density separation system based on light substances and heavy substances in household waste. The density separation system comprises an air separator, a cyclone separator and an induced draft fan. The air separator comprises a heavy substance collecting hopper and an air separation bin, the heavy substance collecting hopper is fixedly installed at the lower end of the air separation bin, an air inlet is formed in the connecting position of the heavy substance collecting hopper and the air separation bin, a heavy substance outlet is formed in the lower end of the heavy substance collecting hopper, a light substance outlet is formed in the upper end of the air separation bin, and a feed port is formed in the inclined lateral wall of the air separation bin. The light substance outlet of the air separator is connected with a tangent material inlet of the cyclone separator through a pipeline and an air outlet of the cyclone separator is connected with the induced draft fan through a pipeline. The density separation system is scientific and reasonable in structural design, stable in running, high in screening efficiency, high in processing speed and capable of effectively separating the light substances from the heavy substances.

Description

technical field [0001] The invention belongs to the field of sorting systems, in particular to a density sorting system based on light objects and heavy objects in domestic garbage. Background technique [0002] Domestic waste can be made into fertilizer after harmless and resourceful treatment. During the treatment process, the waste that has undergone rapid degradation and drying of organic matter in the early stage needs to be further finely sorted to remove smaller-sized waste before making fertilizer. Only by keeping the heavy matter and leaving the light matter can we provide high-quality fertilizer raw materials for the fertilizer system. Heavy objects in domestic waste include metal, stone, sand, soil, battery glass; light objects in domestic waste include kitchen organic matter, plants, abandoned crops, etc. At present, the domestic research on domestic waste mechanical sorting technology and the development of special equipment It started late and the processing m...
