Description
Technical Field
The invention belongs to the technical field of building waste classification and recovery equipment, and particularly relates to blocky building waste classification and recovery equipment.
Background
The construction waste refers to residue soil, waste materials, residual mud and other wastes generated in the process of construction, laying or dismantling and repairing of various buildings, structures, pipe networks and the like of construction units or personal teams.
At present, the quantity of the building garbage in China accounts for 30% -40% of the total quantity of the urban garbage, calculated according to the standard of 500-600 tons/ten thousand square meters, and by 2020, the newly added building area of China is about 300 hundred million square meters, so that the newly generated building garbage is a shocking number. However, most of the construction wastes are not treated at all, and are transported to the suburbs or villages by construction units, and are stacked or buried in the open air, so that a large amount of construction expenses such as land charge and garbage clearing and transporting expenses are consumed, meanwhile, the problems of scattering, dust, ash and sand flying and the like in the clearing and stacking processes cause serious environmental pollution, and the construction department of municipal construction waste management regulations performs the construction in 6 months and 1 day in the last year, and requires that any units and individuals cannot randomly dump, scatter or stack the construction wastes. The resident should collect building rubbish and domestic waste that the house in-process produced with the decoration respectively to stack appointed place, the setting of building rubbish transfer station should make things convenient for the resident. And the unit and the individual who do not dispose the construction waste according to the regulations are given heavy penalties, so that the management of the urban construction waste is enhanced, and the urban appearance and the environmental sanitation are guaranteed. At present, the main treatment method of the construction waste in China is to bury the construction waste underground. The danger is that, above all, a large amount of land is occupied. Only by taking Beijing as an example, the following data are shown: in the prior removal of the original building before the construction of the Olympic project and the construction of a new construction site, twenty-thirty building rubbish digestion sites are required to be arranged every year in Beijing, which causes not little land pressure and serious environmental pollution. The construction glue, coating and paint in the construction waste are not only high molecular polymer materials which are difficult to biodegrade, but also contain harmful heavy metal elements. The waste is buried underground, causes pollution of underground water, directly harms the lives of surrounding residents, and damages soil structures and causes surface subsidence. The current landfill method is: after 8 m of garbage is buried, 2 m of soil layer is buried, but basically vegetation is difficult to grow on the soil layer. The surface of the landfill area is settled and subsided, and a stable state can be achieved after a long time.
Construction waste is often mixed together in the construction, and landfill with rubbish can cause the harm to the environment to in the construction waste can all carry out recycle such as plastics, reinforcing bar, cement.
The prior art also discloses a construction site garbage crushing and classifying recovery device, for example, a Chinese patent with application number 201710701254 discloses a material conveying and overturning device, the construction garbage is placed on a feeding device, the garbage is fed into a crushing box through the feeding device to be crushed, the crushed material moves from the upper surface of a first conveyor belt, along with the rotation of the first conveyor belt, the material inclines down from one side of the first conveyor belt, the metal material is adsorbed, when the first conveyor belt and a second conveyor belt are separated, the attraction force is reduced, so that the material falls into a metal collecting box, the material entering a nonmetal collecting box is heavy at the bottom with high density, the material with low density is suspended on the surface, a push plate rotates, and the suspended material is pushed into a second inner cavity.
The technical scheme achieves the effect of classifying and collecting the metal waste and the nonmetal waste; but this scheme has the rubbish and carries out crushing process and produce more dust easily and the foam is too dispersed after breaking to the poor shortcoming of effect of screening, collection of metal.
