Description

Building rubbish utilization earlier stage handles production line

Technical Field

The invention relates to the technical field of treatment of solid waste of construction waste, in particular to a construction waste resource utilization early-stage treatment production line.

Background

The construction waste refers to residue, waste soil, waste material, sludge and other wastes generated in the process of constructing, laying or dismantling and repairing various buildings, structures, pipe networks and the like by construction and construction units or individuals. The construction waste can be classified into engineering residue soil, decoration waste, demolition waste, engineering slurry and the like according to the production source; the construction waste can be classified into slag, concrete blocks, broken stones, broken bricks and tiles, waste mortar, asphalt blocks, waste plastics, waste metals and the like according to the composition.

The coarse and fine aggregate produced with waste building concrete and waste brick stone may be used in producing concrete and mortar in corresponding strength grade or in producing building material product, such as block, wall board, floor tile, etc. The coarse and fine aggregate can be further processed, such as adding curing materials, and can also be used as a raw material for constructing a road base layer.

For example, Chinese patent No. CN207641992U discloses a construction waste recycling system, which comprises a sorting system, a concrete brick recycling production line, a plastic recycling production line and a wood recycling production line which are arranged behind the sorting system in parallel, wherein the wood recycling production line comprises a crushing device, an iron removing device, a first screening device, a granulating device, a second screening device, a packaging device and a plurality of transferring devices, the crushing device is arranged behind the sorting system, the iron removing device, the first screening device, the granulating device, the second screening device and the packaging device are sequentially arranged behind the crushing device, the transferring devices are arranged between the system and the devices, by the technical scheme, a plurality of types of construction waste can be automatically treated at the same time, the treated products can be directly applied to the industry, the treatment process is high in capacity, the resource utilization rate is high, and the operation cost is low.

For example, chinese patent No. CN109127646B discloses a construction waste recycling process, which includes sorting non-stone materials in construction waste by pretreatment, primary treatment and secondary treatment, separating light materials in the construction waste by a water separation tank without removing the light materials, retaining heavy materials, and separating the heavy materials into block materials and sand materials by a coarse-fine separation mechanism.

However, in the production process of the construction waste recycling base, the problems still exist, the problems are not effectively solved, the processing efficiency and the product quality are easily affected, for example, an important link of metal recovery in raw materials is involved, and in the existing mode, because only one magnet plate is simply arranged above a conveying belt for adsorption, fine metal impurities are easily selected in a missing mode, and the fine metal impurities flow into the next processing procedure. Moreover, the magnet plate is difficult to clean in time after being fully adsorbed with metal impurities, so that the adsorption effect is increasingly poor, and more metal impurities are more easily leaked; for example, some soil or other dust-like fine materials are often adhered to the surface of the construction waste in the existing production line, the adopted soil separation device usually consumes a large amount of water when in use, and the structure is complicated, so that the manufacturing cost is high, more parts cause faults easily, and the maintenance rate and the maintenance difficulty are increased; for example, the dust always existing in a production base is large, a large amount of tiny particles often float in the air of a construction site, the air is purified by sprinkling water or spraying water mist by using a fog gun machine in the conventional method, but water vapor is evaporated quickly, and the dust falling on the ground combined with water drops is blown by wind and then drifts everywhere, so that the respiratory health of construction site workers is continuously influenced. The above outstanding problems affect the production efficiency, water resource utilization, worker breathing health and other important problems, and must be effectively solved to further perfect the production line, continuously optimize the production equipment and process, continuously increase the economic benefits of enterprises, bring greater environmental protection benefits and implement the sustainable development strategy.
