Background technique

In the process of building construction, a lot of construction waste will be produced. These wastes contain powder materials, including some lumps and waste wood, etc., thus limiting the recycling and reuse of construction waste, and some are even directly used for landfill or as Construction waste is thrown away. Due to the various components contained in these waste materials, after some rough treatment, the powder of construction waste can be used as concrete or other interstitial materials, and the blocks can be used as building supports or piles. However, the recycling of construction waste has strict requirements. If it is used as filler aggregate, there are certain requirements for the cleanliness of the aggregate. If the aggregate is not clean or there are too many powders, it will affect the bearing capacity of the building structure. During the process, the powder material will rise, causing secondary pollution. In addition, the use of aggregates is generally divided into coarse aggregates and fine aggregates, and the size of construction waste blocks varies. If it is used as a single aggregate, the waste needs to be processed again, which increases the recycling cost. Manual separation is time-consuming and laborious, and the construction efficiency is not good. It cannot be separated quickly and affects the construction progress. Therefore, it is best to use some mechanized devices to recycle, separate and reuse it.

To sum up, when recycling construction waste in the prior art, there are problems that the cleanliness is not high when used as aggregates, and the aggregates are not effectively classified.
