Description
Technical field
The utility model relates to sewage sludge process field, specifically a kind of sewage sludge electromagnetic force filter-press dehydration dress
It sets.
Background technique
In the prior art, occurring more deep dehydration device for sludge in the market is diaphragm plate frame filter press, when dehydration, effect
Rate is lower, squeeze pressure is only 1.6MPa, and squeezing is injected water into 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,
Structurally, filter plate is all the injection molding module an of entirety to common elasticity squeezing its structure of sheet frame, and filter plate is easy on the market
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 processing disposition subsequent to sludge such as the lime added and iron chloride brings detrimental effect,
Violate 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
The composition such as plate, matching board, spring medium, filter cloth specialized, rear end pair filter plate, push plate, girder, it includes filter which, which squeezes sheet frame,
Frame, filter plate, filter cloth, operating room, spring and piston plate, spring are set between filter frame and filter plate, and piston plate is arranged in operating room
Between filter plate, so that filter plate generates compression to operating room by piston plate.Rammer board dehydration is broadly divided into two-stage,
The first order is that filter chamber is transported material to by feed pump, and charging while is separated by solid-liquid separation by the pressure of feed pump, i.e., one
Secondary filtering means dehydration；The second level is elastic squeezing, and one end of equipment is fixed, and the other end applies ambient pressure by hydraulic cylinder, is led to
It crosses elastic force-transmitting device (spring) compression chamber space and squeezing progress second dehydration is carried out to material.By carrying out superelevation to sludge
Pressure squeezing, for squeeze pressure in 5MPa or so, high-pressure oil pump needs to provide the pressure of 25-30MPa or so, can drop moisture percentage in sewage sludge
To 50% or so.Equally, which realizes the change to sludge pressing chamber volume by setting spring
It realizes that super-pressure squeezes, since spring often completes the processes such as elongation-compression, needs to bear alternating load, spring is easy hair
Raw fatigue rupture, spring is a kind of vulnerable part, and 10-20 high-strength spring, 50-100 block plate are needed between every group of sheet frame
Frame then needs nearly 1000-2000 high-strength spring, moreover, the bullet for also needing to overcome spring initial when squeezing spring
Power effect, actual squeeze pressure suffered by sludge is smaller than the pressure that superpressure oil pump is supplied to when twice pressing.For example, into
When expecting that pressure is 1MPa, spring must be provided greater than 1MPa elastic force, so that the maximization of chamber is able to maintain between filter plate and filter frame,
At the end of feeding 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 are the pressure of consumption, are less than actual pressure to pressure caused by sludge so as to cause high-pressure pump
Power.
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 is under so high pressure and large deformation, the service life problem of diaphragm.
The equipment such as above-mentioned diaphragm plate frame filter press, high-pressure elastomeric machine are all to realize to take off sludge pressing by high-voltage oil cylinder
Water provides power, needs to configure special a set of hydraulic system, and when being high-pressure compressing, hydraulic system pressure is very high.
It needs to pull open filter plate when dump, this requires one special plate pulling devices of configuration to pull open one piece one piece of filter plate, plate pulling efficiency
Lower, the time is long, influences the entire working time.
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
The sludge pressing pressure of diaphragm plate frame filter press is smaller, and super-pressure diaphragm plate frame filter press squeeze pressure is enough, but diaphragm
Life problems；(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) due to dirt
It is de- that high-compressibility, high-moisture percentage and the sewage sludge that sewage sludge has contain sludge caused by capillary water, absorption water and internal water
The feature of water difficulty is difficult to carry out high depth dehydration to sludge completely using mechanical pressure, so that moisture percentage in sewage sludge reaches one
Lower level.
