Description
Technical field
The utility model relates to a kind of device for treating sludge.It specifically, is for the mud generated during river and lake dredging
Starch the integrated treatment unit quickly handled.
Background technique
It is well known that a large amount of mud will necessarily be generated by carrying out dredging to river and lake.Currently, river and lake dredging is mainly using underwater
It stirs the methods of dry digging of suction, artificial hydraulicking or digging machine the sludge treatment in river and lake is debarked, and silt stockyard is selected to carry out heap
It puts, makes its natural consolidation.And it is greater than 30% from the mud of river and lake processing disembarkation in muddy, and the clay content less than 5 microns,
Partial size is small, this is just determined, and river and lake silt moisture content is high, consolidation rate is slow, and intensity is low after consolidation.In addition, some river and lake silts
In, also contain poisonous and harmful substances.
Due to using natural consolidation, consolidation rate is slow, occupies a large amount of soils, causes the waste of land resource.
Again since the mud intensity after consolidation is low, not only Exploiture of cropland utilization cannot be directly carried out in stockyard, can not also made
It is used for engineering earth.
In addition, after consolidation, meeting rain drop erosion due to containing poisonous and harmful substances in some river and lake silts, not only weighing
New argillization becomes mud again, and poisonous and harmful substances therein are easy exudation, can cause secondary pollution to environment.
Utility model content
Problem to be solved in the utility model is to provide a kind of river and lake silt integrated treatment unit.At this device
River and lake silt is managed, engineering earth is can be used not only as, avoids argillization again, eliminate the secondary pollution of environment, also can avoid soil money
The waste in source.
The above problem to be solved in the utility model is realized by the following technical scheme:
The river and lake silt integrated treatment unit feature of the utility model is: including sorting mechanism, flocculation basin, dewaterer and
Curing, between sorting mechanism and flocculation basin, flocculation basin be connected by dredge pump between dewaterer, the dewaterer is by conveyer
It is connected with curing.
The sorting mechanism is vibrating screen or drum screen, deposits mud sump below sorting mechanism, deposits Chi Kou and the screening of mud sump
Mechanism is corresponding on perpendicular direction.Described deposit is connected between mud sump and flocculation basin by a dredge pump.
The flocculation basin contains pond body and the first blender.
The dewaterer is high pressure plate and frame filter press or supercentrifuge.
The conveyer is screw conveyor or belt conveyor.
The curing contains storage hopper dredger and the second blender.
Since the river and lake silt integrated treatment unit of the utility model contains sorting mechanism, flocculation basin, dewaterer and consolidates
Change machine, between sorting mechanism and flocculation basin, flocculation basin be connected by dredge pump between dewaterer, the dewaterer by conveyer with
Curing is connected.By the utility model, the river and lake silt that can be come out in real time to dredging directly carries out integrated treatment.With background
River and lake silt, which is piled up stockyard, in technology allows its natural consolidation to compare, and consolidation rate is fast, does not have to silt stockyard, is not take up soil,
Avoid the waste of land resource.Again due to that can be screened, be flocculated to the river and lake silt of dredging by the utility model, be dehydrated
And solidification, river and lake silt after processing, can be used as backfill, dyke, road and greening soil, realize dredging and sludge treatment
Seamless interfacing will be that the river and lake silt of waste becomes useful soil resource originally.In addition, due to real using the utility model
The seamless interfacing for having showed dredging and sludge treatment is not required to silt stockyard, and chance water washes away mud again after not only can avoid silt consolidation
Change, become the generation of the case where mud again, and can avoid the exudation of the poisonous and harmful substances in yard sludge, to eliminate
Caused by environment secondary pollution.
