Description
Technical field
The utility model relates to sewage sludge process field, specifically a kind of multi-chamber multistage filters pressing sludge dewatering dress
It sets.
Background technique
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, resource utilization etc. all adversely affect.Therefore, deeply dehydrating sludge minimizing is sludge
Primary and foremost purpose is handled, minimizing is the basis for realizing sludge other " three change ", and sludge is more dry, disposes 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
Lower, 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 duty cycle is long.In addition,
On the market common elasticity squeezing sheet frame structure structurally, filter plate is all the injection molding module an of 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, thus greatly
The amount of sludge is increased greatly, and the meeting such as the lime added and iron chloride processing disposition subsequent to sludge brings unfavorable shadow
It rings, violates the minimizing and innoxious principle of specific resistance to filtration.
Current there are also a kind of superelevation compression elasticities to squeeze sludge dewatering equipment, which mainly includes high-voltage oil cylinder, superelevation filters pressing
Plate, matching board, spring medium, filter cloth specialized, tailgate, push plate, girder etc. composition, 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 to operating room by piston plate.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 device (spring) compresses chamber space and carries out squeezing progress second dehydration to material.By carrying out super-pressure squeezing to sludge,
For squeeze pressure in 5MPa or so, high-pressure oil pump needs to provide the pressure of 25-30MPa or so, moisture percentage in sewage sludge can be down to 50%
Left and right.Equally, which realizes the change to sludge pressing chamber volume by setting spring to realize
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 frame then needs
Will nearly 1000-2000 high-strength spring, moreover, the elastic force that also needs to overcome spring initial when squeezing spring is made
The actual squeeze pressure suffered by sludge when, twice pressing is smaller than the pressure that superpressure oil pump is supplied to.For example, charging pressure
When power is 1MPa, spring must be provided greater than 1MPa elastic force so that be able to maintain the maximization of chamber 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.
For existing market there are also a kind of super-pressure diaphragm plate frame filter press, which is on original diaphragm plate frame filter press
Upgrading, the water by injecting 10MPa in diaphragm provides the nearly pressure of 10MPa to sludge, and is second level expressing process,
Feed pressure is begun through, highly pressurised liquid is then injected in diaphragm, bulging is carried out to diaphragm, further sludge is pressed
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 the deep dehydration of Yao Shixian 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

Service life is not high；(2) superelevation compression elasticity squeezer is the variation for realizing sludge pressing chamber volume by spring, and spring is easy to damage
And a large amount of squeeze pressure can be consumed；(3) pressure is bigger, more solid in the sludge being tightly attached on filter plate, and easy to form one
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) all pressures
Power arises directly from the pressure of high-voltage oil cylinder, not the enlarger Jing Guo any power, leads to oil cylinder working-pressure and oil cylinder volume mistake
Greatly, to equipment sealing and reliability more stringent requirements are proposed.
