Description
Technical field
The present invention relates to a kind of building castoff recyclings to recycle disposal impurity-removing method.
Background technology
Existing building changing rejected material to useful resource recycles dry treatment impurity-removing method mainly to have sorting and selection by winnowing, and selection by winnowing can be set
Before broken two, may also set up two it is broken after.
Because the sundries ingredient in building castoff is complex, only it is difficult to simple sorting and selection by winnowing by building castoff
In sundries removal it is clean, selection by winnowing be arranged on two it is broken before, it is substantial amounts of miscellaneous that the armored concrete in building castoff is easy to winding
Object causes to be difficult to sort and selection by winnowing, influences aggregate percentage of impurity, selection by winnowing be arranged on two it is broken after, two it is broken before manual sortings be difficult that will build
Sundries sorting in discarded object is clean, is difficult to be incited somebody to action with single selection by winnowing into the material particular diameter difference in size in selection by winnowing process is larger
Two it is broken after material wind selection it is clean.
The content of the invention
To solve the deficiencies in the prior art, at a kind of building castoff recycling recycling
Impurity-removing method is put, building castoff recycling can be solved and recycle that be only difficult in disposal by selection by winnowing and manual sorting will be in material
Sundries remove clean difficult point.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that:
A kind of building castoff recycling recycles disposal impurity-removing method, including following processing step:
Step 1, sort:Building castoff is sorted by sorting equipment to remove miscellaneous in building castoff
Object;
Step 2, two is broken:Second-time breakage is carried out to the building castoff after the completion of sorting by crusher;
Step 3, magnetic separation:It is miscellaneous to reject ferrous metal that magnetic separation is carried out to two building castoffs after the completion of broken with concentration equipment
Object;
Step 4, sieve:The building castoff after the completion of magnetic separation is sieved using screening plant;Screening plant is set
It is more than the first grain size and the building castoff less than the second grain size for double deck screen to screen out grain size;First grain size is equal to broken
The maximum discharging grain size of machine;
Step 5, selection by winnowing:Selection by winnowing is carried out to the building castoff after the completion of screening using pneumatic separator;Removal impurity simultaneously stays
Lower aggregate;Second grain size is in the range of pneumatic separator institute energy selection by winnowing.
Further, screening plant is vibrating screen.Further, vibrating screen includes at least two different sieves of screen size
Net.
Further, crusher is impact breaker.Further, crusher crushes for jaw crusher or cycle
Machine.Further, crusher is cone crusher or kibbler roll.Further, crusher is hammer mill.Into one
Step ground, crusher is vertical shaft impact crusher.
The invention has the beneficial effects that:
Screening process is set after being broken two, the material that two are not smashed in broken and the larger material progress of grain size after two is broken
It screens out, and the material of minimum grain size will be required to screen out the choosing of laggard sector-style less than air separation technique, to reach that material wind selection is clean
Effect.
The method of the present invention can reduce sorting process and divide sorting net rate requirement, for two windings of armored concrete before broken
Sundries can wouldn't need to sort, and eliminate security risk.
Using screening in a manner that selection by winnowing is combined, solves selection by winnowing during current building castoff recycling recycles
Material particular diameter span is big, the ineffective difficult point of selection by winnowing.
Description of the drawings
Fig. 1 is the FB(flow block) that a kind of building castoff recycling recycles disposal impurity-removing method.
Specific embodiment
Make specific introduce to the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of building castoff recycling recycles disposal impurity-removing method, including following processing step:
Step 1, sort:Building castoff is sorted by sorting equipment to remove miscellaneous in building castoff
Object.The larger bulk sundries of volume in emphasis removal building castoff.
Step 2, two is broken:Second-time breakage is carried out to the building castoff after the completion of sorting by crusher.Material after broken
Grain size is more than the material of the maximum discharging grain size of crusher to need the impurity removed.
Step 3, magnetic separation:It is miscellaneous to reject ferrous metal that magnetic separation is carried out to two building castoffs after the completion of broken with concentration equipment
Object.
Step 4, sieve:The building castoff after the completion of magnetic separation is sieved using screening plant;Screening plant is set
It is more than the first grain size and the building castoff less than the second grain size for double deck screen to screen out grain size;First grain size is more than or equal to broken
The maximum discharging grain size of machine.One layer of sieve of double deck screen of screening plant screens out grain size building more than the maximum discharging grain size of crusher
Discarded object is built, another layer of strainer screens out the smaller substance of grain size, so as to follow-up selection by winnowing.
Step 5, selection by winnowing:Selection by winnowing is carried out to the building castoff after the completion of screening using pneumatic separator;Removal impurity simultaneously stays
Lower aggregate;Second grain size is in the range of pneumatic separator institute energy selection by winnowing.
Building castoff is sieved first before selection by winnowing is carried out, can effectively control the grain into the material of selection by winnowing
Footpath.Convenient for selection by winnowing material particular diameter than controllable, it is easier to realize optimal selection by winnowing effect.The heavy substance that selection by winnowing process leaves is aggregate,
Light materials are impurity.Screening and selection by winnowing are combined the building castoff after disposal, can substantially reduce and percentage of impurity is obtained in aggregate, improve
Aggregate quality.
Further, screening plant is vibrating screen.Vibrating screen includes at least two different sieves of screen size.
As a kind of optional specific embodiment, crusher is impact breaker.As another optional specific
Embodiment, crusher are jaw crusher or gyratory crusher.As another optional specific embodiment, crusher is
Cone crusher or kibbler roll.As another optional specific embodiment, crusher is hammer mill.As
Another optional specific embodiment, crusher is vertical shaft impact crusher.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the invention is not limited in any way above-described embodiment, all to be obtained by the way of equivalent substitution or equivalent transformation
Technical solution is all fallen in protection scope of the present invention.
