Description
Technical field
The invention belongs to discarded concrete utilization technology fields, and specifically, it is discarded mixed to be that a kind of high-volume is newly mixed
Solidifying soil recoverying and utilizing method and system.
Background technique
Concrete mixing plant often generates a large amount of discarded concrete, such as concrete transportation in production management process
The remaining coagulation of concrete and the sampling of concrete factory testing is spread in leakage under residual concrete, facilities of mix storied building on vehicle, stirring host
Soil etc..What is generallyd use at present is that the sand-stone separator of rotary screen formula separates discarded concrete, and is washed away in separation with water
Concrete, then sand, the stone after separation are recycled, and waste pulp again return clear water after multifeed clarifier and filter press processing
It receives and utilizes, the waste residue outlet of filters pressing or the raw material as other auxiliary products.The process of recycling is not only troublesome and can only solve
A small amount of recycling for newly mixing discarded concrete, and other is moved back, is reported because of a large amount of remain that irresistible reason generates
Waste concrete can not be then recycled, and still can only be carried out outlet, be caused very big waste, increase cost, and
Outlet place is difficult to look for, extremely disadvantageous to environmental protection.Although having had enterprise in view of such problems at present, by sandstone
The waste pulp generated after seperator recycling sandstone are used for the production again of concrete, but are also faced in waste pulp containing a large amount of fine sands,
The problems such as solid content fluctuation is larger, is unfavorable for the quality control of concrete production.
Summary of the invention
To solve the above-mentioned problems, object of the present invention is to be intended to provide a kind of sand by the surplus concrete for moving back, scrapping, stone
Utilization is separately recovered, and the high-volume that the waste pulp of generation are used for fresh concrete reproduction is newly mixed into discarded concrete recycling benefit
Use method.
To realize the above-mentioned technical purpose, The technical solution adopted by the invention is as follows:
A kind of high-volume newly mixes method for recycling waste concrete, comprising the following steps:
Step 1: the sandstone in discarded concrete is separated and recovered；
Discarded concrete is transported in sand-gravel separation device using loading machine and is separated, isolated sand, stone are distinguished
Recycling is used for the reproduction of fresh concrete, and the waste pulp of generation are discharged into waste pulp pond.
Step 2: waste pulp are recycled；
Using cyclone the waste pulp in waste pulp pond are carried out with fine sand separation again and obtains fine sand and recycling slurry, later returns fine sand
The reproduction for being used for fresh concrete is received, and recycling stock pump is entered into the solid content with Weighing mechanism and is adjusted in tank.
Step 3: it is allocated as recycling slurry to be used to produce the new slurry of fresh concrete；
The load-carrying that solid content adjusts tank is weighed by Weighing mechanism, is adjusted with solid content and fills recycling slurry in tank, and recycled in slurry
Load-carrying of solid content when being 10% be standard load-carrying, solid content is adjusted when filling recycling slurry slurry in tank, recycles the liquid level of slurry solid
Content is adjusted at the overflow port of tank；When the load-carrying that solid content adjusts tank is less than or equal to standard load-carrying, recycling slurry is discharged into and is stirred
It mixes in pond；When the load-carrying that solid content adjusts tank is greater than standard load-carrying, clear water is discharged into solid content and adjusts the bottom of tank, and is passed through
The recycling slurry of spilling is flow back to waste pulp pond by the overflow port that solid content adjusts tank top, until the load-carrying that solid content adjusts tank is equal to mark
When quasi- load-carrying, then recycling slurry is discharged into stirring pool.
To solve the above-mentioned problems, it is another object of the present invention to be intended to provide in a kind of concrete that surplus will be moved back, scrap
Sand, stone is separately recovered utilization, and the high-volume that the waste pulp of generation are used for fresh concrete reproduction newly mixed discarded coagulation
Native recycling system.
A kind of high-volume newly mixes discarded concrete recycling system, including sand-gravel separation device and waste pulp pond, the sand

Specific embodiment
In order to make those skilled in the art that the present invention may be better understood, with reference to the accompanying drawings and examples to this hair
Bright technical solution further illustrates.
A kind of high-volume newly mixes method for recycling waste concrete, comprising the following steps:
Step 1: the sandstone in discarded concrete is separated and recovered；
Discarded concrete is transported into sand-gravel separation device using loading machine and is separated, isolated sand, stone are distinguished
Recycling is used for the production of fresh concrete, and the waste pulp of generation are discharged into waste pulp pond；
Step 2: waste pulp are recycled；
Using cyclone the waste pulp in waste pulp pond are carried out with fine sand separation again and obtains fine sand and recycling slurry, later returns fine sand
The production for being used for fresh concrete is received, and recycling stock pump is entered into the solid content with Weighing mechanism and is adjusted in tank.
Step 3: it is allocated as recycling slurry to be used to produce the new slurry of fresh concrete；
By Weighing mechanism weigh solid content adjust tank load-carrying, because fresh concrete production when used in pulp-water solid content not
10% can be higher than, then canned full recycling slurry is adjusted with solid content, and recycling the load-carrying when solid content in slurry is 10% is that standard carries
Weight M, i.e., load-carrying when solid content adjusts canned Qing Dynasty's water is m, then standard load-carrying M passes through formula: M ρ water/10 ρ consolidate+9M/
10=m is obtained, and wherein ρ water is the density of water, and ρ is the density of solid in pulp-water admittedly, and lot of experimental data show that the solid value of ρ is about
2.5g/ml, then standard load-carrying M=50m/47；When the load-carrying that solid content adjusts tank is less than or equal to 50m/47, then recycling is starched
It is discharged into stirring pool；When the load-carrying that solid content adjusts tank is greater than 50m/47, clear water is discharged into the bottom that solid content adjusts tank, and
The higher recycling slurry of solid content is flow back in waste pulp pond by the overflow port that solid content adjusts tank top, until solid content adjusts tank
Load-carrying when being equal to 50m/47, recycling slurry is discharged into stirring pool and is used for the production of fresh concrete.In the present embodiment, by right
Discarded concrete is separated, and is handled waste pulp are generated, and the sand, stone and solid content of recycling waste pulp up to standard are recycled and are used
In the production of fresh concrete, recycling for resource is realized, reduces outlet destruction caused by environment.
In order to further save water resource, in above-described embodiment, preferably: carrying out sandstone separation in sand-gravel separation device
