Abstract
The invention relates to a method for regenerating bricks and tiles from construction waste. The method is characterized by comprising the steps: (1) carrying out sorting: decomposing reinforced concrete refuse into small blocks, stripping reinforcing bars from the small blocks, and then, collating and placing the stripped reinforcing bars elsewhere; separating wood, plastics and metal from bricks, tiles, small concrete blocks, aerated concrete blocks, floor tiles, wall tiles and glass construction waste, classifying and collating the wood, plastics and metal, and placing the classified and collated wood, plastics and metal elsewhere; (2) carrying out coarse grinding: putting the separated concrete, bricks, tiles and small glass waste blocks, from which other materials are removed, into a ball mill, carrying out coarse grinding, separating pebbles and a powder material from the mixed material, and separately placing the pebbles and the powder material; (3) carrying out cleaning and screening: flushing and screening pebble-shaped granular waste, and then, placing the screened pebble-shaped granular waste in a classified manner; separately recovering waste water and pond sludge; and (4) carrying out fine grinding and molding: putting the classified powder material into a fine grinding mill for fine grinding, adding a cementing material, filler, an additive and water into the fine-ground material, carrying out stirring, then, putting the mixture into a porous brick molding machine, carrying out pressurized vibratory molding so as to form porous bricks, and stacking and curing the formed porous bricks.
Description
Technical field
The present invention relates to refuse reclamation, particularly construction refuse regenerated.
Background technology
Along with the development of urban construction, the rubbish that removal, building, finishing bring gets more and more, and these building wastes at present except landfill, stack, do the basis and bed course of building except, the project recycled after carrying out reclaiming processing is less, recycling rate is low, and to be regenerated as brick and tile be Recent study important topic, but generally all needs through firing, cause secondary pollution, be unfavorable for environmental protection.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, provide a kind of method of regenerating bricks and tiles from building refuses, method is simple, and raw material is extensive, non-secondary pollution, environmental protection.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of method of regenerating bricks and tiles from building refuses:
The first step, sorting: Steel Concrete garbage decomposition is fritter, and is separately put from Final finishing by steel bar peeling wherein; Brick, watt, little block concrete, air-mixed concrete pieces, floor tile and wall tile, the timber in glass architecture rubbish, plastics, metal separation goes out and taxonomic revision is separately put;
Second step, corase grind: by above-mentioned removing its also the concrete of class, brick, watt, glass rubbish fritter drops in ball mill and roughly grinds, be separated the stone in compound and powder, and place respectively;
3rd step, cleaning screening: stone shape particle rubbish sorts out placement after rinsing screening; Waste water and pond mud reclaim respectively;
4th step, fine grinding are shaping: dropped in atomizer mill by sorted powder and carry out fine grinding, and add agglutinate, filler, compound and water, after stirring, drop into pressurization and vibration in shaping machine of porous brick shaping, make perforated brick, piling maintenance.
Described agglutinate is inorganic materials or macromolecular organic compound material; As unslaked lime, cement, water glass etc.
Described filler is flyash or slag.
Described compound is calcium lignin sulphonate.
The water added in described 4th step is the waste water of the 3rd step clean and reuse.
The inventive method is reasonable, technique is simple, by building waste taxonomic revision, that can directly recycle separately puts, the stone not directly recycled, mineral substance garbage decomposition large volume, mix grinding become stone shape particle and powder, rinse stone waste water reclamation, mix each component by composition brick proportioning raw materials, stir blanks and moulding and conserving piling.Not only by building waste classification process, and it is various to obtain product, and better performances, does not produce secondary pollution in production process, the equal recoverable of waste material waste water, environmental protection.Improve building waste recovery utilization rate, at utmost reduce building waste to the pollution of environment.
Embodiment:
Embodiment 1
A kind of method of regenerating bricks and tiles from building refuses:
The first step, sorting: Steel Concrete rubbish employment hammer pounds into fritter, and is separately put from Final finishing by steel bar peeling wherein; Brick, watt, little block concrete, air-mixed concrete pieces, floor tile and wall tile, the timber in glass architecture rubbish, plastics, metal separation goes out and taxonomic revision is separately put;
Second step, corase grind: by the concrete of above-mentioned other classes of removing, brick, watt, glass rubbish fritter drops in ball mill and roughly grinds, be separated the stone in compound and powder, and place respectively;
3rd step, cleaning screening: stone shape particle rubbish sorts out placement after rinsing screening; Waste water and pond mud reclaim respectively;
4th step, fine grinding are shaping: dropped in atomizer mill by sorted powder and carry out fine grinding, and add flyash or slag, unslaked lime, calcium lignin sulphonate, waste water, after stirring fully mixing, drop into pressurization and vibration in shaping machine of porous brick shaping, make perforated brick, piling maintenance.
Embodiment 2
Be raw material production regeneration brick according to method described in embodiment 1 with building waste, the first step is identical to the 3rd step, 4th step, fine grinding are shaping: dropped in atomizer mill by sorted powder and carry out fine grinding, and add flyash or slag, water glass, calcium lignin sulphonate, waste water, and little work stone, after stirring fully mixing, drop into pressurization and vibration in shaping machine of porous brick shaping, make perforated brick, piling maintenance.
