The treating construction waste method of the present invention has the following advantages that：
1st, the preliminary screening that equipment completes building waste using apron feeder, apron conveyor, rotary screen removes earth process,
The soil that particle diameter is more than 40mm is isolated from building waste, urban afforestation or digging up and filling in soil can be used as；
2nd, using toothed roll crusher, with reduction ratio is big, noise is small, vibration is small, crushing quantity is few, dust is few, energy consumption excessively
Low, floor space is small, easy to maintenance power consumption is small the advantages of facilitate, the characteristics of be difficult putty；Compared to other coarse smash equipments (such as jaw
Formula disintegrating machine) the characteristics of can more be adapted to contain reinforcing bar in building waste, it can peel off concrete and reinforcing bar well, reclaim steel
Muscle.
3rd, using bar screen, sieve plate is in interdigitated electrode structure, is become larger along discharging direction space width, is thus avoided that sieve plate
It is blocked, screening efficiency is higher.Isolate particle diameter and be less than 100mm building wastes, reduction subsequent artefacts' sorting more than 100mm, particle diameter
Pressure.
4th, can be by light materials, dangerous substance, derivatived fuel and the unsuitable debris subsequently disposed point by artificial separation
Sort out and.
5th, one-level magnetic separation process uses gallus-type tramp iron separator, can be by magnetic things such as the iron classes mixed in building waste
Matter is sorted out.
6th, two-stage crushing process uses impact breaker, big with reduction ratio, and the characteristics of disposal ability is big is broken in being adapted to
Process, is less than 40mm by construction waste crushing to particle diameter.
7th, the totally-enclosed sieve that two grades of screening processes are used, good leak tightness, treatment effeciency is high, sieve aperture 20mm.
8th, in order to strictly control the granularity of aggregate, using the totally-enclosed sieves of 40mm, particle diameter is more than 40mm bulk building waste
Impact breaker progress closed cycle is back to crush.
9th, one-level broken process is before artificial separation process, and toothed roll crusher can peel off the reinforcing bar in building waste
Out reclaim, the iron class material of intermediate fraction can be picked out in artificial separation process, fine-grained iron class material can be
The suspender belt magnetic separation in artificial separation room is selected.The high purpose for removing iron rate can thus be reached.
10th, one-level sieves process before artificial separation process, can be respectively enterd by building waste according to grain size grading
One artificial separation conveyer, so design are avoided because a sortation conveyor material stores up too high, the debris of small grade
The drawbacks of cannot effectively sorting.
11st, two grades of screening processes are before two kinds of selection by winnowing modes, because the corresponding effective sorting material of two kinds of selection by winnowing modes
Granularity is different, the disposal ability of two kinds of equipment is also different, so can preferably play two kinds of selection by winnowing modes optimum efficiency and
Design.
12nd, the purpose of three-level screening process (40mm classifying screens) is can to control the grade of final aggregate well, strictly
Control meets the granularity requirements of recycled product.Particle diameter, which is more than 40mm, to be back in impact breaker, can thus reach brokenly
The closed cycle of broken system.
Above example is only the exemplary embodiment of the present invention, is not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can make respectively in the essence and protection domain of the present invention to the present invention
Modification or equivalent substitution are planted, this modification or equivalent substitution also should be regarded as being within the scope of the present invention.
