Embodiment Construction

[0038] The following is attached Figure 1-4 The application is described in further detail.

[0039] The embodiment of the present application discloses a method for producing clean regenerated soil and regenerated aggregate by using construction waste. refer to figure 1 , the method for producing clean regenerated soil and regenerated aggregate from construction waste comprises the following steps:

[0040]Primary screening: manually select bare metal, plastic, glass, rubber, wood, cardboard, and linoleum from construction waste, and then use a magnetic separator to screen reinforced concrete from construction waste to obtain primary construction waste and reinforced concrete waste , the magnetic separator in this step adopts a special magnetic separator, which can absorb the reinforced concrete with large weight and small steel bar content;

[0041] Metal collection: put the reinforced concrete waste into the crusher, break the reinforced concrete, so that the steel bars...

Abstract

The invention relates to a method for producing clean recycled soil and recycled aggregate by using construction waste, and relates to the technical field of construction waste treatment. The method comprises the six steps of primary screening, metal collection, secondary screening, soil separation, secondary crushing and aggregate screening. Reinforced concrete in the metal waste is subjected to magnetic separation and then crushed, so that the situation that a crusher is clamped by metal such as steel bars in construction waste during crushing can be reduced, crushed concrete blocks are processed to be used as aggregate, recycling of reinforced concrete in buildings is achieved, magnetic separation is conducted on the reinforced concrete firstly, mixing of concrete powder and soil after the reinforced concrete is crushed can be reduced, and subsequent recycling of soil is facilitated. The method has the effect of improving the recycling rate of construction waste.

Description

technical field [0001] The application relates to the technical field of construction waste treatment, in particular to a method for producing clean regenerated soil and regenerated aggregate by using construction waste. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals. [0003] At present, the final disposal of construction waste in my country is mainly backfilling. Except for a few cities, most cities do not have special landfills for construction waste, and most of the construction waste is directly transported to the suburbs or villages without any treatment, and is disposed of by open-air stacking or landfilling. Filling consumes a large amount of land resources and poses a great safety risk. In addition, problems such as air dust and sewage pollu...
