Description
Technical field
The present invention relates to sewage sludge process field, specifically a kind of clamshell type press filtration sludge dehydration device.
Background technology
Sludge high-moisture percentage is the bottleneck for restricting specific resistance to filtration, and the high sludge of moisture content is not only bulky, but also
Contained a large amount of organic matters, heavy metal and harmful microorganism is also easy corruption or can be discharged into environment, and causes secondary pollution, to dirt
The subsequent landfill of mud, burning, recycling etc. all adversely affect.Therefore, deeply dehydrating sludge minimizing is sludge
Primary and foremost purpose is handled, minimizing is to realize the basis of sludge other " three change ", and sludge is more dry, is disposed to subsequent processing more advantageous.
The common dehydration equipment of early stage sludge has plate and frame filter press, drum centrifuge and belt type filter filter press, through these
After equipment dehydration, moisture percentage in sewage sludge generally in 75%-80%, these sludge because moisture content is excessively high, and cause transport inconvenient and at
This is higher, and drying time can not be caused long in landfill yard Direct Disposal, the large amount of organic that contains in sludge and abundant
The nutrients such as N P and K, perishable generation stench cause environmental pollution.
It is currently on the market diaphragm plate frame filter press with more deep dehydration device for sludge, but in dehydration, efficiency
Relatively low, squeeze pressure is only 1.6MPa, and squeezing is injected sewage inside diaphragm plate frame by high-pressure hydraulic pump, and bulging diaphragm reduces
Filter chamber area, diaphragm plate frame are squeezed by the plastic deformation of sheet frame；Diaphragm plate frame compression ratio is small, and the opposite work period is long.In addition,
On the market common elasticity squeezing sheet frame structure structurally, filter plate is all the injection molding module of an entirety, and filter plate is easy
Impaired deformation, and the filter plate after damage needs integral replacing so that maintenance cost is higher, it is often more important that, due to structure
Feature and squeeze pressure be not high, the currently employed diaphragm plate frame filter press may by municipal sludge press dewatering to 60% or so,
It is reduced much than plate and frame filter press moisture content before, main cause is because diaphragm bulging generates twice pressing to sludge, i.e.,
Sludge press filtration chamber is variable chamber, but the equipment needs to add the lime and molysite of over dry mud amount 30% or so, to big
The big amount for increasing sludge, and the meeting such as the lime added and iron chloride processing disposition subsequent to sludge brings unfavorable shadow
It rings, violates the minimizing of specific resistance to filtration and innoxious principle.
Currently there is a kind of superelevation compression elasticity to squeeze sludge dewatering equipment, which includes mainly high-voltage oil cylinder, superelevation press filtration
The compositions such as plate, matching board, spring medium, filter cloth specialized, tailgate, push plate, girder, the super-pressure squeezing sheet frame include filter frame, filter plate,
Filter cloth, operating room, spring and piston plate, spring are set between filter frame and filter plate, piston plate setting operating room and filter plate it
Between so that filter plate generates compression by piston plate to operating room.Rammer board dehydration is broadly divided into two-stage, and the first order is
Filter chamber is transported material to by feed pump, charging while is separated by solid-liquid separation by the pressure of feed pump, i.e., primary filtering is de-
Water；The second level is elastic squeezing, and one end of equipment is fixed, and the other end applies ambient pressure by hydraulic cylinder, is passed by elasticity
Power apparatus (spring) compresses chamber space and carries out squeezing progress second dehydration to material.By carrying out super-pressure squeezing to sludge,
In 5MPa or so, high-pressure oil pump needs to provide the pressure of 25-30MPa or so squeeze pressure, can moisture percentage in sewage sludge be down to 50%
Left and right.Equally, which is realized by the way that spring is arranged to realize the change to sludge pressing chamber volume
Super-pressure squeezes, and since spring often completes the processes such as elongation-compression, needs to bear alternating load, spring is easy to happen fatigue
It destroys, spring is a kind of vulnerable part, and 10-20 high-strength spring is needed between every group of sheet frame, and 50-100 block sheet frames then need
Will nearly 1000-2000 high-strength spring, moreover, also needed to when squeezing spring the elastic force for overcoming spring initial work
Actual squeeze pressure is smaller than the pressure that superpressure oil pump is supplied to suffered by sludge when, twice pressing.For example, charging pressure
Power be 1MPa when, spring must be provided more than 1MPa elastic force so that the maximization that chamber can be kept between filter plate and filter frame, when into
At the end of material squeezing, when high-pressure pump carries out second of high-pressure compressing to sludge, it is necessary to overcome spring to start possessed elastic force,
This partial pressure is the pressure of consumption, is less than actual pressure to pressure caused by sludge so as to cause high-pressure pump.
It is on original diaphragm plate frame filter press that existing market, which also has a kind of super-pressure diaphragm plate frame filter press, the equipment,
Upgrading, the water by injecting 10MPa in diaphragm provides the nearly pressure of 10MPa to sludge, and is two level expressing process,
Feed pressure is begun through, highly pressurised liquid is then injected in diaphragm, carrying out bulging to diaphragm further presses sludge
Dehydration is squeezed, municipal moisture percentage in sewage sludge can be down to 50% or so after equipment dehydration.There are a main problems to be for the equipment
Diaphragm influences the problem of the service life of diaphragm under so high pressure and large deformation.
By analyzing above, it can be seen that realize that the deep dehydration of sludge has to realize sludge pressing chamber volume
Changeability, while to sludge carry out high-pressure compressing.Either diaphragm plate frame filter press or superelevation compression elasticity squeezer all has
There is the changeability of sludge pressing chamber, but there are following main problems for deep dehydration device for sludge at present：(1) commonly

The closely knit sludge blanket of layer, the sludge blanket are bonded on filter cloth, increase moisture and resistance is discharged, influence dehydrating effect；(4) due to sewage
High-compressibility, high-moisture percentage and the sewage sludge that sludge has contain capillary water, adsorb sludge dewatering caused by water and internal water
