Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of construction waste recycling, and particularly relates to a treatment mechanism for construction waste recycling. BACKGROUND

[0002] With the rapid development of the construction industry, the amount of construction waste continues to increase, among which concrete blocks, steel prefabricated plates, hollow aluminum profiles and the like are the main components of the construction waste, and such materials have high recycling value, and recycling and processing thereof can not only reduce resource waste, but also reduce environmental pressure, and is an important direction of construction waste resource utilization.

[0003] In the prior art, there are many deficiencies in the recycling process of such construction waste.

[0004] Firstly, in actual construction waste, the surfaces of concrete blocks, steel prefabricated plates and hollow aluminum profiles are often attached with wet cement paste, mortar, paint residues and the like (especially for a construction site just removed, the construction waste is not completely dried), and all mechanism designs (conveying, screening, cutting and adsorption) of the existing patents are based on the assumption that the material surface is dry and non-sticky for direct transmission and crushing, which may cause problems such as slippage, blockage and uncontrolled material conveying of the mechanism.

[0005] Secondly, when the metal inside the plate is sorted, only the sorting of magnetic metals is usually performed, and the existing technology mostly adopts a single sorting method, which is difficult to achieve accurate grading and separation according to the physical properties of different non-magnetic metals, resulting in incomplete separation of non-magnetic metals and impurities such as concrete aggregates.

[0006] Thirdly, the crushed materials are often directly fed into the sorting link without effective flattening and scattering treatment, and the materials are prone to stacking, so that part of the metal particles are shielded by the aggregates in the subsequent metal sorting process, and cannot be fully identified and separated. In addition, the existing magnetic metal removal mechanism is mostly fixedly arranged, cannot act synchronously with the flattening process, is difficult to fully cover the flattened materials for removal, is prone to missing selection of magnetic metals, and lacks effective timing control and convenient cleaning structure for cleaning the magnetic metals on the surface of the magnetic adsorption component, and the adsorption force will decrease due to metal accumulation after long-term use.
