Description

Technical Field

[0001] The invention relates to the technical field of construction waste disposal, and in particular to a high-precision purification device for recycled aggregates from construction waste. Background Art

[0002] At present, the main methods of disposal of construction waste are landfill, incineration and resource utilization. Among them, resource utilization is regarded as an environmentally friendly and sustainable way. By separating and processing recyclable resources in construction waste, new building materials or other products are produced, which not only reduces the amount of construction waste generated, but also reduces environmental pollution.

[0003] Due to the complex composition of construction waste, if it is not sorted cleanly, the recycled aggregates produced will contain more light material impurities such as plastics, films, wood chips, etc., affecting the subsequent resource utilization.

[0004] At present, the light materials in construction waste are mainly separated by positive pressure air separation. However, the premise of this separation method is that the specific gravity of the light and heavy materials to be separated must be greatly different and the particle size range must be 50mm-150mm. Only in this way can the light and heavy materials be effectively separated by positive pressure air separation. However, the recycled aggregates produced after multi-stage crushing and screening of construction waste mostly have a particle size of less than 30mm. It is difficult to effectively separate the light material impurities in the recycled aggregate by positive pressure air separation, resulting in low purity of the recycled aggregate and poor performance.
