Description
Technical field
The invention belongs to sludge dewatering technical field, it is related to a kind of river and lake silt special filtering sheet frame and river and lake silt special
High-pressure pressure filter.
Background technology
China region is wide, and in length and breadth, each river course and lake carry the drinking of city, flood discharge, row to city river
The functions such as flood, tourism, shipping, with economic fast development, the utilization of resources is extensive, and various industry, house refuse and sewage are not
The phenomenon arbitrarily discharged through treatment is of common occurrence, along with soil erosion, causes river channel sedimentation, not only have impact on the basic of river course
Function, if things go on like this, increases the safety and sanitation hidden danger in city.On the riverbed of city, such case will be for a large amount of sludgd depositions
Long-term existence in regular period.The river in contaminated river course remains in a standstill, river channel sedimentation, and water body is muddy even black smelly showing occurs often
As.Originally as life and the urban river water at industrial water water source, its function has been severely impacted.The beautification ring that river course has
The functions such as border, regulation city miniclimate, landscape tourism are also greatly reduced.The deposition in river course, silt up and make shipping, flood control function notable
Degenerate, and stream entering lake pollution or most of lake pollutions and eutrophication main cause.Due to the deterioration of river course water environment
Urban life environment and the landscape is not only set to receive destruction, and the heavy damage original function of river ecosystem and stabilization
Property.Therefore, city river is desilted and dredged and is attached most importance to, and water environment improvement is carried out comprehensively, very urgent.
During desilting, it is key issue that how the mud of removing is processed.Practice have shown that, mud usually contains substantial amounts of
The material such as organic matter, pathogenic microorganism, heavy metal and nitrogen, phosphorus, due to its poor permeability, mud be difficult to during pressure-bearing by
Pore water is discharged, and long-term immersion forms thick hydrated sheath, causes sludge to consolidate difficult, does not have bearing capacity, and be pressurized easy rheology, is in
Stream modeling shape.Obviously, if it is possible to dehydration and drying is carried out to mud in a short time, its volume is dramatically reduced, not only subtracts
Small transport pressure, while also for follow-up disposal provides conditioned basic.Therefore, the online drying technique of mud and equipment are developed,
Fast and reliable end disposing technique is formed, the effective desilting to realizing river lake is very crucial.
The characteristics of river and lake silt is sad filter, and treating capacity is very big.The existing mechanical filter to river and lake silt is typically adopted
With chamber-type press filter (its filter chamber is made up of the filter plate of adjacent two pieces depressions, and filter cloth is fixed on every piece of filter plate), van-type pressure
Filter is primarily present that filter pressure low (only 0.6MPa), filter residue moisture content (70% or so) high, batch time be long, filtering rate
Slow the shortcomings of.
Or mechanical filter is carried out to sludge with high-pressure elastomeric squeezer.But existing high-pressure elastomeric squeezer, its filtering
Plate frame structure is complex, generally comprises bearing plate and push plate, is set on same circumference between pressure-bearing sheet frame and pushing sheet frame
There are some Packing springs；What is had also includes movable filter plate and fixed filter plate, in same circumference between movable filter plate and fixed filter plate
It is provided with some ejector springs for automatic discharging.Using this internal filtering sheet frame for setting spring, there is feed pressure
The defect such as low, filtering rate is low, service life is short, using the high-pressure elastomeric squeezer of this filtering sheet frame with spring, it takes off
Aqueous energy, disposal ability, separating effect are limited, also there is filter pressure and filter efficiency is low, equipment investment operation integrated cost
High defect.Due to river and lake silt filtration treatment, it is desirable to which treating capacity is very big, feed pressure is big, therefore, existing use band
The high-pressure elastomeric squeezer of the filtering sheet frame of spring is not particularly suited for carrying out mechanical filter to river and lake silt.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of bearing capacity is big, filtering rate is high, treatment
Amount is big, the river and lake silt special filtering sheet frame of long service life, while also provide that a kind of filter pressure is high, filter residue moisture content is low,
Filtering rate river and lake silt special high-pressure filter press high.
