Description
Technical field
The present invention relates to a kind of building castoff recyclings to recycle method of disposal.
Background technology
Existing building castoff disposal of resources technique is usually single line disposal, is selected in two broken advance sector-styles, wherein building
The removal of impurities of discarded object is built mainly using the fritter light materials in a building castoff after broken first are carried out selection by winnowing separation, is then existed
Selection by winnowing sets manual sorting later, and the impurity that selection by winnowing is not fallen carries out manual sorting, so as to reach removal of impurities.
The method of disposal wall scroll treating capacity of single line is big, and the treating capacity of separate unit pneumatic separator is extremely difficult to single line currently on the market
Selection by winnowing requirement, single device selection by winnowing is ineffective, and the first selection by winnowing method that manual sorting cleans again, the object after being broken because of one
Many light materials can mutually be wound again together in material, and a broken laggard sector-style choosing is difficult that these substance selection by winnowing are gone out, and is manually divided
It picks and also is difficult to be sorted totally, which obtains aggregate percentage of impurity and be difficult to ensure that；No brick mixes separating technology, is produced
Rate containing brick is higher in aggregate, can not be applied to high-strength products raw material, and product utilization value is low.Without aggregate shaping process, give birth to
Concrete glass is not clean in the recycled aggregate of output, and aggregate crush values are high；Secondary removal of impurities is carried out by the way of manual sorting,
Labor intensity is big, and disposal efficiency is low, and there are security risk, the material uncertain factor after sorting is more.
The content of the invention
To solve the deficiencies in the prior art, at a kind of building castoff recycling recycling
Method is put, manual intervention degree can be reduced, is utilized and is worth higher recycled aggregate.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that：
A kind of building castoff recycling recycles method of disposal, including following processing step：
Screening one：Building castoff is sieved and is excluded the smaller material of grain size as dregs；
One time brick mixes sorting：Separation equipment is mixed by brick, sorting is mixed to the building castoff brick of progress by screening one
Building castoff is divided into the higher concrete material of amount containing concrete and the higher material of brick of amount containing brick to separate brick and concrete block；
Robot sorts：Robot point is carried out to the concrete material after a brick mixes separation using robot sorting equipment
It picks；
Concrete line two is broken：Concrete material after the completion of being sorted using crusher to robot carries out second-time breakage；
Screening two：Concrete material of the concrete line two after broken is sieved to screen out in the concrete material after second-time breakage and is less than follow-up selection by winnowing
The material of one minimum particle size set；
Selection by winnowing one：Selection by winnowing is carried out to the concrete material that screening two leaves；
Secondary brick mixes separation：Secondary brick is carried out to the concrete material after selection by winnowing one and mixes separation, with the rate containing brick of reduction；
Aggregate shaping：The concrete material after separation is mixed to secondary brick and carries out aggregate shaping, is obtained with the concrete for removing concrete material surface
Obtain recycled aggregate one；
Manual sorting：Manual sorting is carried out to the material of brick after a brick mixes sorting；
Brick line two is broken：The material of brick after manual sorting is crushed using crusher；
Magnetic separation three：Magnetic separation is carried out to the material of brick of the brick line two after broken to remove ferrous metal impurity；
Screening three：The material of brick after magnetic separation three is sieved to obtain recycled aggregate two.
Further, secondary brick mix the separated material of brick can be mixed by screening three after the material of brick as recycled aggregate two.
Further, building castoff recycling recycles method of disposal to further include following processing step：Selection by winnowing two：To brick
Material carries out selection by winnowing.Further, selection by winnowing two carries out multiple selection by winnowing or repeatedly selection by winnowing.
Further, building castoff recycling recycles method of disposal further comprising the steps of：One is broken：Using crusher
Building castoff after sieving a step is crushed；Magnetic separation one：To by broken a treated building castoff into
Row magnetic separation is to remove ferrous metal impurity；The building castoff handled by magnetic separation one is delivered to brick and mixes separation equipment progress once
Brick mixes sorting.
Further, building castoff recycling recycles method of disposal further comprising the steps of：Magnetic separation two：To concrete line two
It is broken that treated that concrete material carries out magnetic separation to remove ferrous metal impurity；The material of brick handled by magnetic separation two carries out three steps of screening.
Further, robot sorting substitutes manual sorting.Further, secondary brick mixes side of the separation using photometric sorting
Method realizes that brick mixes separation.Further, the broken used crusher of concrete line two is jaw crusher or cone crusher.Into one
Step ground, the broken crusher used of concrete line two is impact breaker.Further, the broken crusher used of brick line two is reaction type
Crusher.
The invention has the beneficial effects that：
Larger-size impurity in removal building castoff is sorted by robot, then carries out smashing material after concrete line two is broken
The optimal impurity-eliminating effect of material is realized in laggard sector-style choosing.
Sorting is mixed by a brick, disposal line is divided into concrete line and brick line cleans respectively, the removal of impurities amount of single line subtracts
Few, impurity-eliminating effect more preferably, and mixes separation by secondary brick, and the rate containing brick in concrete material can be controlled effectively, and recycled aggregate one can be with
Applied to raw material such as strong concretes, product utilization value is high.
Material is identified by computer vision, and passes through robot and machine is carried out to the impurity for recognizing the need for sorting
Device people is sorted to substitute manual sorting, and product percentage of impurity is guaranteed, and reduces human intervention degree.
Using aggregate shaping process, can concrete material be subjected to better concrete stripping, one crush values of recycled aggregate are low, aggregate
Application value is high.
Brick line two is broken to be arranged among Xun Huan returning charge, can material be carried out multiple selection by winnowing, so as to reduce in recycled aggregate
Percentage of impurity, aggregate utility value are high.
