Description
Technical Field
The invention belongs to the field of special mechanical equipment for efficiently converting solid garbage or waste into renewable resources, and particularly relates to a skid-mounted mobile solid waste treatment and machine-made sand production integrated device.
Background
The construction waste refers to the general name of dregs, waste concrete, waste bricks and stones and other wastes produced by people in the production activities of the construction industry such as demolition, construction, decoration and repair. 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 stone blocks, broken bricks and tiles, waste mortar, slurry, asphalt blocks, waste plastics, waste metals, waste bamboo and wood and the like according to the composition.
The construction waste refers to construction waste generated by human or natural reasons in engineering, and comprises waste residue soil, waste soil, silt, waste materials and the like. These materials are not helpful to the construction itself, but are substances generated in the construction process, and need to be treated correspondingly, so that the ideal engineering project construction can be achieved, and because the materials are an integral process, the link consideration is more important.
With the development of society and the continuous improvement of the living consumption of people, the garbage generated every year also grows explosively. As 2011, the stock of solid domestic garbage in China reaches 70 hundred million tons, the total quantity of construction garbage can be calculated to be 21 hundred million to 28 hundred million tons, and more than 3 hundred million tons of construction garbage are newly generated every year. If a simple stacking mode is adopted for treatment, the newly added construction waste occupies 1.5 to 2 hundred million square meters of land each year. China is in the period of high-speed development of economic construction, and hundreds of millions of tons of construction wastes are inevitably generated every year. If the treatment and the utilization are not carried out in time, adverse effects are inevitably brought to the society, the environment and resources. According to the research and analysis of the 'national institutes of environmental sanitation building waste management and resource working committee', the annual production amount of the building waste including the building waste and the engineering waste soil in China is about 35 hundred million tons in 2015, wherein 15 hundred million tons of the building waste are produced by only dismantling annually. The quantity of the construction waste in China accounts for 30 to 40 percent of the total quantity of the urban waste. Reckoning by the standard of 500-600 tons/ten thousand square meters, as far as 2020, the newly increased building area of China is about 300 hundred million square meters, and the newly generated building garbage is a shocking number. However, most of the construction wastes are not treated, and are transported to the suburbs or villages by construction units, and are piled or buried in the open air, so that a large amount of construction expenses such as land acquisition expenses and garbage clearing and transporting expenses are consumed, and meanwhile, the problems of scattering, dust, sand flying and the like in the clearing and piling processes cause serious environmental pollution. The resource utilization rate of the construction waste is only 5 percent. At present, the construction waste is consumed mainly by landfill and stacking. The mode has the main harm that a large amount of land is occupied, so that the waste of land resources is caused, and the urban appearance environment is influenced by the badges and raised dust in the illegal clearing and stacking process to heavily and circularly fill the dirt beam.
Therefore, the method is obvious that the urban solid waste is large in scale in China, and the comprehensive utilization of the construction waste is an effective way for saving resources and protecting ecology. After being sorted, removed or crushed, most of the wastes in the construction wastes can be reused as renewable resources, such as: the metal such as waste steel bars, waste iron wires, waste electric wires and various waste steel fittings can be used for replacing sand, building mortar, plastering mortar, making concrete cushions and the like, and can also be used for manufacturing building material products such as building blocks, paving bricks, lattice bricks and the like. At present, the comprehensive utilization of construction waste has the following ways:
(1) 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. After the coarse and fine aggregates are added into the curing material, the material can also be used for a road surface base layer.
(2) The aggregate produced by using the waste bricks and tiles can be used for producing building material products such as regenerated bricks, building blocks, wall boards, floor tiles and the like.
(3) The dregs can be used for road construction, pile foundation filling, foundation base and the like.
(4) For waste wood building garbage, wood which is not obviously damaged can be directly reused for reconstructing buildings, and wood members which are seriously damaged can be used as raw materials of wood regenerated boards or for papermaking and the like.
(5) The waste pavement asphalt mixture can be directly used for regenerating asphalt concrete according to a proper proportion.
(6) The waste road concrete can be processed into recycled aggregate for preparing recycled concrete.
(7) The waste steel, the waste steel bar and other waste metal materials can be directly reused or processed by returning to the furnace.
(8) The construction wastes such as waste glass, waste plastics, waste ceramics and the like are utilized differently according to the situation.
In this regard, developed countries such as japan, the united states, germany, and the like have been conducting relatively early, and have provided us with a number of advanced experiences and treatment methods. The sand making system is the main mechanical equipment for reproducing the available sand stone by the existing solid waste, and plays an important role in solid waste treatment. The prior sand making machine mainly has the following problems: the energy consumption is large, the installation time of the previous equipment is long, and the investment is high; the noise and dust have serious influence on the surrounding environment; the requirement on production site conditions is high, and the production land is large; complicated operation procedures, etc. This series of problems indicates that existing sand making systems have not met the ever-increasing work efficiency and environmental requirements.
