Description
Technical field
The present invention relates to concrete mixing plants, and specifically a kind of concrete mixing plant sewage waste residue recycles system
System and its equipment.
Background technique
With the development of economy with the progress of technology, the environmental protection, energy conservation and usability that quotient mixes mixing plant are proposed higher
Requirement.The recycling of concrete waste material, the processing of sewage increasingly cause enterprise and society especially in concrete production enterprise
Concern.The sewage generated during discarded concrete and concrete production is very serious to the pollution of environment, it is necessary to be returned
It receives and utilizes.
There are two types of existing take-back model is general, concrete directly is transported to pump one is the pulp-water after sandstone separation and is stirred
Production is participated in mixing equipment；One is pulp-water is carried out filters pressing, the filter residue filter cake obtained after filters pressing is disposed again after drying.The
One mode can not be finished, and pulp-water can be more and more denseer the problem is that the amount of pulp-water is very big, blocking stirring easy to attach
Pond and conveyance conduit cannot pass through force (forcing) pump, it is necessary to individually enter mixed due to containing a certain amount of fine sand and handstone in pulp-water
In solidifying soil blender, just cause sewage that can not accomplish sprinkling uniformly in this way, mixing time needs to lengthen；The problem of second of mode
The filter residue filter cake for being generation is all to be disposed by drying after exposing to the weather, then to the filter residue filter cake dried, and dispose general
It also needs to pay certain expense.
A kind of new concrete mixing plant sewage waste residue recycling system of this patent disclosure proposes a kind of new
The scheme that pulp-water utilizes solves the problems, such as conventional process scheme.More thoroughly and rationally to the utilization of pulp-water, more
Environmental protection and energy saving.
Summary of the invention
The present invention provides a kind of concrete mixing plant sewage waste residue recycling systems, it is to concrete mixing plant sandstone
Pulp-water after separation is separated by solid-liquid separation again, to after separation of solid and liquid clear water and waste residue recycle, on the one hand reduce
Damage of the waste water to stirring pool, conveyance conduit and force (forcing) pump, in addition, promote the effect that waste residue recycles.
The present invention realizes that above-mentioned purpose uses following technical scheme:
A kind of concrete mixing plant sewage waste residue recycling system, the pulp-water after it separates sand-stone separator carried out
Filter obtains separation clear water and waste residue after filtering；The described separation clear water for mixing plant production or to concrete delivery truck into
Row cleaning of evaporator；The waste residue is used to the production of mixing plant or is back in pulp-water be stirred again uniformly.
A kind of concrete mixing plant sewage waste residue recycling equipment, it includes sand-stone separator, pulp-water stirring pool, pulp-water
Secondary filter system is additionally provided between stirring pool and mixing plant.
The secondary filter system includes filter device and separation clear water reserviors, and the filter device is centrifugal separator
Or filter press；The input terminal of the filter device corresponds to pulp-water stirring pool, and it is clear that the output end of filter device corresponds to separation
Pond and waste residue storage warehouse；It is set in separation clear water reserviors there are two water pump, respectively metering water pump and concrete delivery truck cleaning of evaporator adds
Water water pump, metering water pump are connected to the water weighing bucket of concrete mixing plant by concrete production water lines, and concrete delivery truck is washed
Tank adds water water pump to lead to concrete mixer truck by concrete delivery truck cleaning of evaporator filler pipe road；Waste residue storage warehouse corresponds to concrete
Produce oblique rubber conveyer.
The waste residue storage warehouse lower part is delivered to the feeding portion of pulp-water stirring pool or mixing plant by transfer device respectively；
Waste residue weighing bucket is additionally provided between transfer device and the feeding portion of mixing plant.
The transfer device is metering rubber belt, and the metering rubber belt is bidirectional rotating type structure, measures rubber
One end of band leads to pulp-water stirring pool, and the other end leads to waste residue weighing bucket；Concrete production is corresponded to below the waste residue weighing bucket
Oblique rubber conveyer.
It is equipped with weighing sensor in the waste residue storage warehouse and waste residue weighing bucket, is equipped with slurry in the pulp-water stirring pool
Water liquidometer, the separation clear water reserviors are interior to be equipped with separation clear water liquidometer.
The present invention has the advantages that by adopting the above technical scheme
1, the utilization of pulp-water is more simple, is separated by solid-liquid separation again to pulp-water, generates a large amount of separation clear water and few
The waste residue of amount；The solid separated in clear water is less, will not adhere to, and does not need the timing agitation of pulp-water, it is easily stored and
Conveying；Obtained waste residue amount very little, can be incorporated into concrete production according to certain proportion, save cost.
2, the utilization of pulp-water is more thorough, carries out the separation clear water obtained after being separated by solid-liquid separation again and waste residue to pulp-water and obtains
Sufficient utilization is arrived, separation clear water is for putting into production or carrying out cleaning of evaporator operation to concrete delivery truck, and waste residue then can be with
The production for directly participating in concrete, can substitute a part of fine sand and powder admixture, realize the zero-emission of pulp-water on the whole.
3, the waste residue after pulp-water separation using more reasonable, not Tongfang is carried out by the waste residue generated after separating to pulp-water
To transhipment realize the comprehensive and reasonable of waste residue utilized, can be selected as needed, when needing waste residue to be given birth to as raw material
Waste residue is directly output to the manufacturing side of concrete mixing plant when production；When not needing waste residue as a raw material for production, waste residue is conveyed
To pulp-water stirring pool, the waste residue of remaining is stirred evenly by stirring with pulp-water, is ready to be separated by solid-liquid separation next time.
This ensure that the freshness of waste residue, makes it that can direct plunge into production and carry out using eliminating the place of filter residue filter cake
Set spent time and expense.
