DC current.Multistage loadings are on each negative electrode, anode.It is clamped in thickness 40mm mud cake between anode assembly and cathode assembly
There are electro-osmotic effects.Now low pressure oil cylinder open feeding squeezing program, hydraulic means oil supply cylinder provide pressure, oil cylinder piston to
Before be slowly advanced, mud cake is squeezed, the water being appeared by electric osmose in circular mud cake passes through heat-resisting filter cloth with Interstitial Water form, real
Existing mud-water separation, circular mud cake final thickness is reduced to 12-15mm by 40mm, and in mud cake, 62.5% ~ 70% moisture is removed, from
And realize sludge drying purpose.The pressure of low-pressure hydraulic oil cylinder can be as desired by control valve regulation.
When machine no longer water outlet, barrier film internal squeeze water emptying, pressure-air quickly enters patch between filter cloth and mud cake
Conjunction face, blows mud cake, is forcibly separating mud cake and filter cloth.After plate left by machine, mud cake leans on gravity to depart from filter cloth, anode plate automatically,
Fall on material pulling car, mud cake is transported outward.
Cylinder efficient illustrates:
Operating pressure-such as the 2.0mpa of hydraulic system before work, is mixed up according to squeezing job requirement.During squeezing, hydraulic pressure
System is passed through hydraulic oil by oil connection toward in hydraulic cylinder, and oil cylinder piston is limited by hydraulic cylinder and guide cylinder,
Under hydraulic oil promotes, oil cylinder piston moves forward.It is fixed on filter disc on oil cylinder piston together with cathode screen, filter cloth to reach
Dynamic, extrude mud, thus reaching the purpose of dehydration.
The utility model such as prior art hydraulic means, high-frequency rectification power supply and high-pressure cleaning system are not remake and retouches
State.
This electro-osmosis high pressure sludge filter press structure is simple, firmly, reliable, long service life, processes 1 ton 80% and contains
Water rate mud, energy consumption as little as 80kwh, can quickly realize moisture percentage in sewage sludge and be reduced to less than 40%, take off than common diaphragm filter press
Water efficiency improves twice, and because of filter chamber between required thrust little, can increase filter chamber quantity, improve filter press treatment effeciency and
Disposal ability.
The above, the only preferable specific embodiment of the utility model, but the utility model protection domain does not limit to
In this, any be familiar with those skilled in the art of the present technique in the technical scope that the utility model discloses, can readily occur in change or
Replace, all should cover within the utility model protection domain.Therefore, the utility model protection domain should be with claims
Protection domain is defined.
