Description
Technical field
The invention belongs to build solid wastes recycling utilization, building material field, it is related to a kind of building solid waste best quality to process
Technique.
Background technology
With greatly developing for China's infrastructure construction, old building, road etc. are pulled down and removed a building for reconstruction, house, urban operating mechanism
Deng extensive newly-built, the building solid waste of flood tide is generated, according to statistics, the current annual production of China about at 2,000,000,000 tons or so, build by reserves
Solid waste is built about at 20,000,000,000 tons, the severe contamination of environment, soil, air, water resource is caused.Current China's building solid waste is most
Based on landfill, it is impossible to fundamentally solve the process problem of building solid waste, waste substantial amounts of land resource.
China's building demolition scene does not carry out genealogical classification to building solid waste, significantly increases building solid wastes recycling and utilizes
Difficulty.Building fixed-end forces only realize simple crushing and screening at present, generally comprise the operations such as broken, magnetic separation, screening.
According to building solid waste type, the difference of reconstituted product demand, also without for the maturation for mixing the system disposal of building solid wastes recycling
The problems such as technology, generally existing shortage system removal of impurities means, low treatment effeciency, unstable product quality.Typically build at present
Fixed-end forces are built for regeneration aggregate, only with the low value-added product such as regeneration brick, regenerative building block, makes recycling
Enterprise is difficult to produce a profit.The regeneration aggregate crush index that produces simultaneously, being also difficult to reach GB containing miscellaneous, apparent density etc. will
Ask, it is more difficult to applied in concrete.
The content of the invention
The technical problems to be solved by the invention are directed to the deficiency of above-mentioned prior art presence and provide a kind of building admittedly
Useless best quality handling process, realize the finer efficient sorting of building solid waste, realizes best quality, high added value, stable performance
Reconstituted product.
The present invention is to solve the problems, such as that used technical scheme set forth above is：
One kind building solid waste best quality handling process, comprises the following steps：
(1) building solid waste is air-dried in closing stockyard, is ensured that building solid waste moisture content is maintained at less than 10% as far as possible；
Then preliminary manual sorting is carried out, rag, plastics, glass, electric wire, timber etc. is sorted out as far as possible, be that follow-up separation mitigates
Pressure；
(2) the remaining building solid waste after step (1) is sorted is delivered to heavy stripping sieve, screens out the clod for mixing, then
Oscillating feeder is delivered to again, and 0~80mm particle diameters building solid waste part therein is directly entered one-level screening, other remaining portions
It is broken into one-level after dividing ancestor's work point to sort out the materials such as rag, plastics, glass, electric wire, timber, substantially remain in particle diameter
100~below 150mm, then carry out magnetic separation and remove old metal and manual sorting going out the light thing such as rag, plastics, glass, electric wire, timber
Matter；
(3) step (2) gained building solid waste is divided into particle diameter 0-15mm, 15-45mm, 45-65mm, 65-85mm and
Five parts of more than 85mm；Wherein, the part of particle diameter 0-15mm is directly as gardens soil or filling soil；The light thing of remainder
Matter separator sorts out the light materials such as rag, timber, plastics again；
(4) color sorting is carried out to step (3) gained particle diameter 45-65mm, 65-85mm building solid waste, realizes brick and coagulation
The sorting of soil more than 90%；
(5) brick and concrete for being sub-elected to step (4) carry out two-stage crushing, magneticly elect old metal and selection by winnowing successively respectively
Go out light materials separation, two grades of screenings；Wherein, brick by two grades sieve after be divided into particle diameter 20-31.5mm, more than 31.5mm and
20mm three below part, then, the brick of below particle diameter 20mm directly carries out combination grinding, prepares surface area more than 350m2/kg
Novel green high-activity mineral blending material, the brick of particle diameter 20-31.5mm crushed by three-level prepare particle diameter 0-5mm mortar,
Conserving material in concrete, the brick of more than particle diameter 31.5mm carries out step (5) again；Concrete is divided into grain after two grades are sieved
Footpath respectively in the common regeneration aggregate of 0-5mm, 5-20mm and 20-31.5mm, and more than particle diameter 31.5mm concrete, should
The concrete of more than particle diameter 31.5mm step (5) again；
(6) color selection by winnowing is carried out to step (3) gained particle diameter 15-45mm, more than 85mm building solid wastes, sub-elects glass
Afterwards, two-stage crushing is carried out successively, magneticly elect old metal and selection by winnowing go out light materials, two grades screening, it is particle diameter 0-5mm, 5- to sieve
The part of the common regeneration aggregate of 20mm, 20-31.5mm and more than particle diameter 31.5mm；
(7) granule strength to the part of step (6) gained more than particle diameter 31.5mm is higher, carries out two-stage crushing, magnetic separation
Remove old metal, screening and obtain particle diameter respectively in 0-5mm, the high-strength and high performance regeneration aggregate of 5-20mm, 20-31.5mm.
By such scheme, the glass that the step (6) sub-elects, grinding to grinding specific grain surface product is more than 350m2/
Kg, as novel green repeat glass micro mist high-activity mineral blending material.
By such scheme, all broken, screening processes include broken one-level, one-level screening, two-stage crushing, two grades sieve,
