Description
Technical field
The system that the utility model is related to a kind of dehydration of on-site slurry, for river course, lake, drainage dredging and other
The discarded slurry that approach is produced, fast dewatering processing is carried out with producing in mud.
Background technology
River course, lake, drainage pipeline networks desilting be solve water body treating must be through step, but traditional Dredging Construction mode
Landfill disposal turns into pollution source to the mud of generation nearby, and the mud without producing secondary pollution focuses on mode then mud
Cost of transportation is high, speed is slow, land seizure is more, the bottleneck factor as restriction water body treating.
At present, the Dredging Construction mode for the non-secondary pollution that most of Dredging Construction enterprise uses is as follows：Built first
Dam stop operation, then break up bottom sludge using hydraulic giant, then by mud be drawn into tank car transport to Treatment stations store, finally
Sedimentation concentration and filter-press dehydration are carried out in Treatment stations to fill into mud cake outward transport.This traditional operating type takes time and effort, especially
Be slurry transportation link occupy processing cost more than half.
The method that can be dehydrated on the spot to mud in desilting site is still the bottleneck of dredging operation technology.It is clear at present
Silt slurry dehydration, which is also no lack of, there are some new techniques, such as folded spiral shell machine evaporation, but comparatively speaking, mud at present
Dehydration production or using the high energy consumptions such as traditional high-pressure filteration, centrifugal force separate, reduction process speed as main flow dewatering process.
First, conventional mud dewatering
There are high pressure sheet frame filtration method, sleeping spiral shell centrifugal separation, belt filter press technique using more mud dewaterion method at present
Deng.
1. high pressure sheet frame filtration method
High pressure plate-frame filtering is a kind of filtering dewatering method of batch (-type), is typically used to compare a small amount of slurry dewatering, greatly
The plate-frame filtering device of type is huge, and installed power is high, it is necessary to which firm carrying is basic.High pressure plate-frame filtering is generally adapted in fixation
Mud conditioning workshop in use, live simple and crude environment is used with being less compliant in desilting mud output.
2. sleeping spiral shell centrifugal separation
Sleeping spiral shell centrifugal separation is a kind of continuous filtering dewatering method, is generally used for small, a small amount of slurry dewatering of density,
Large-scale centrifuge is bulky, and installed power is very high, it is necessary to which the basis especially consolidated, is not suitable for often mobile place and uses.
Horizontal screw centrifuge is generally adapted to be used in fixed mud conditioning workshop, be not suitable for substantially desilting mud output it is existing
The simple and crude environment of field is used.
3. belt filter press technique
Belt filter press technique is a kind of filtering dewatering method of continous way, is typically used to compare at the slurry dewatering easily filtered
Reason.Large-scale belt filter press is bulky, and installation accuracy is high, and the technical requirements of maintenance maintenance are high, it is necessary to the carrying base consolidated
Plinth.Belt press filtration is generally adapted to be used in fixed mud conditioning workshop, is less compliant in the simple and crude of desilting mud output ground
Environment is used.
2nd, slurry dewatering new method
Above-mentioned mud dewaterion method is the widest main stream approach of current domestic application.In recent years, some new mud take off
Water method is also constantly being emerged in large numbers, than it is more typical be exactly folded spiral shell press dewatering method.
The main body of folded spiral shell squeezing dewatering machine is layered on top of each other by retainer ring and travelling ring, the mistake that helical axis is formed therethrough
Device is filtered, leading portion is concentrating part, and back segment is de-watering section, form filter seam between retainer ring and travelling ring, the pitch of helical axis is from dense
Contracting portion is tapered into de-watering section.After flocculation concentration, de-watering section is shifted onto by helical axis in concentrating part for mud, in the mistake of advance
As filter seam and pitch are tapered into journey, and back pressure plate barrier effect, produce great internal pressure, volume constantly contracts
It is small, reach the purpose being fully dehydrated.
Folded spiral shell press dewatering acc power is smaller, device volume is small, is increasingly becoming the head of sewage plant dehydrating residual active sludge
Choosing, but be due to its dehydration dependent on the filter seam abjection moisture formed between retainer ring and travelling ring, when there is sand in mud
When, tiny sand can be extruded in filter seam, cause filter seam to be stretched, and mud and water fold spiral shell directly from filtering in seam out
Press dewatering can not just be carried out；After other sand is entered in filter seam, ditch is ground on retainer ring, travelling ring and helical axis
Groove, retainer ring, travelling ring and helical axis are just scrapped and need to change.Due to a large amount of sands of generally existing in desilting mud,
And it is substantially totally unrealistic that these sands, which are removed, therefore the clear slurry dewatering effect of folded spiral shell machine is very unstable, main
Wanting part, the life-span is very short because of sand abrasion, so being still difficult in adapt to large-scale production and application at present.
