Description

Technical Field

[0001] The present invention belongs to the technical field of garden greening waste treatment and resource utilization, and particularly relates to a garden greening waste treatment system. Background Art

[0003] Garden greening waste is rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium. If it is crushed, piled up, retted, and fermented nearby at the source, it is an ideal garden greening substrate, which can be recycled for urban garden greening planting and the courtyard, balcony flowers, and vegetable planting of residents' families. It can not only reduce the stacking of waste, significantly improve the environment, but also greatly reduce the energy consumption and carbon emissions brought by long-distance transportation, which is very beneficial to promoting the construction of a waste-free city and a green and low-carbon city.

[0004] However, at present, there is no integrated system equipment on the market that can meet the requirements of crushing treatment and resource utilization of urban garden greening waste. Common equipment such as wood chipper, straw shredding machine, shredder, hammer mill, etc. These equipment either mainly process some thicker branches or mainly process some small and long branches and leaves. They cannot uniformly process common urban mixed garden greening waste, and there are also problems of excessive noise and dust generated during operation, which are difficult to meet the urban requirements for noise and dust pollution control. Therefore, at present, the garden greening waste generated in cities is basically stacked for a long time and then transported out of the city for disposal or incineration after accumulating to a certain quantity.

[0005] Therefore, it is very necessary and valuable to develop an integrated crushing system equipment that can not only meet the needs of crushing and composting resource utilization of urban mixed garden greening waste but also meet the urban requirements for noise and dust control.
