Embodiment
Referring to figs. 1 to shown in Figure 4, a kind of sludge concentration and dewatering integration apparatus, described equipment comprise mud mixing and feeding device, rotation propelling gravity dehydration device 7, filter pressing device and mud cake outlet 15;
Described mud mixes and feeding device, comprises being arranged on mud agitated pool 3 and sludge carrier pipe 6 on the frame 31, and described mud agitated pool 3 is provided with mud inlet 1, feeding opening 2, is provided with the agitating vane 5 that is driven by motor 4 in the mud agitated pool 3; The top of described sludge carrier pipe 6 and mud agitated pool 3 is connected; Described frame 31 is preferably made with stainless steel.
Described rotation advances gravity dehydration device 7, comprises screen cloth rotating cylinder 9, drainage pipeline 10 and lower curtate water leg 11, and described screen cloth rotating cylinder 9 is by motor 8 controls; The mud that comes out from sludge carrier pipe 6 is delivered directly to rotation propelling gravity dehydration device 7, when motor 8 runnings drive 9 rotations of screen cloth rotating cylinder a large amount of free-waters is deviate from as much as possible, free-water advances gravity dehydration device drainage pipeline 10 directly to be discharged to lower curtate water leg 11 through rotation simultaneously.
Described filtration pressing device comprises strainer 12, lower filter belt 14 and some dehydration cylinders 32, described dehydration cylinder 32 S-shaped being distributed between strainer 12 and the lower filter belt 14.Under the control of motor 13, the operation in the same way simultaneously of last strainer 12 and lower filter belt 14, advance the dehydration of gravity dehydration device 7 through rotation after, the mud that water ratio is low falls after the processing of screen cloth rotating cylinder 9 at last strainer 12, drive along with last strainer 12, mud drops then on lower filter belt 14, until in the wedge type zone that last lower filter belt forms.Enter the S shape zone by 32 one-tenth of cylinder structures then, under the effect of strainer tension force, mud is subjected to holds extruding, forms certain pressure gradient between strainer and the dehydration cylinder 32, makes mud be subjected to becoming big expressing process gradually by pressure, and its stroke is a S shape.Be clamped in up and down the squeeze that the mud between two strainers is subjected to increasing step by step and the effect of shearing force, make the free-water of mud, interstitial water be come out by press filtration as much as possible, directly arrive mud cake at last and export 15.
For mud cake is come off, specially export 15 places and be provided with dumping device at mud cake, described dumping device is made up of knife rest 16, takeoff apron 17 and back-moving spring 18, and the quantity of knife rest 16, takeoff apron 17 and back-moving spring 18 is two.
After mud becomes cake, better make sludge dewatering for making next time, the side of specially going up lower filter belt is provided with strainer washing unit 29 respectively, and described strainer washing unit 29 is provided with filter cloth washing pipe 26, and preferably the body refuse of mud cake is rinsed out by the water strong pressure of 30 li of flushing pipes.
In conjunction with Fig. 1, in order to make the lower filter belt rate of tension suitable, preferably one tightening device is set in last lower filter belt one termination, this device is meant the tightening pulley 20 by cylinder 19 controls; In conjunction with Fig. 6, in order better to control the pressure of cylinder, the preferred relief valve 21 of installing on gas piping.
By shown in Figure 1, in sludge dewatering simultaneously, in order to prevent the strainer sideslip, be provided with cylinder automatic regulating device on described on the strainer 12 by cylinder 23 and cylinder 25 controls.Cylinder one end is fixed with cylinder, has certain stroke, runs into when going up filter cloth sideslip switch 22 when last strainer 12 sideslips, and cylinder 23 discharges the gas in the cylinder at once, makes the sideslip strainer slowly adjust to the equilibrium theory of tide, recovers certain pressure in the cylinder simultaneously.In like manner, lower filter belt 14 centring device forms are identical, and when the lower filter belt sideslip was run into down filter cloth sideslip switch 24, this moment, the cylinder 25 of lower filter belt sideslip discharged gas in the cylinder at once, made the sideslip strainer slowly adjust to the equilibrium theory of tide, recovered certain pressure in the cylinder simultaneously.Fig. 6 is tightening device and cylinder automatic regulating device gas circuit control chart;
The described strainer tension force of going up strainer 12 and lower filter belt 14 preferably is controlled at 50N-78N/cm.Cycloidal-pin wheel and electromagnetic adjustable speed motor associating speed governing are adopted in the transmission of strainer.Carry out the Artificial Control speed belt speed of travel and be 1-10 rice/minute, usual dispatch be generally 2-3 rice/minute.
Mix firm stainless steel frame 31 by above structure, formed a kind of sludge concentration and dewatering integration apparatus physical construction that makes.Integral part is equipped with automatically controlled again, has just formed the sludge concentration and dewatering integration apparatus of controllable diversification.
The dehydration working process of sludge concentration and dewatering integration apparatus can be divided into flocculation, rotation advances gravity dehydration, transition dehydration, four primary processes of filter-press dehydration.
The mud flocculation process: after the thorough mixing, flocculation agent coheres the solid phase particles in the mud in stirred pot for spissated mud of process and certain density flocculation agent, produces coacervation, makes solid phase and liquid phase separation.
Rotation advances gravity dehydration: flocculation mud later arrives rotation through sludge carrier pipe 6 and advances gravity dehydration device 7, in 9 rotations of screen cloth rotating cylinder how a large amount of free-waters may be deviate from.
Excessive dehydration: mud is distributed on the strainer after advancing gravity dehydration through rotation, drops to again subsequently on the lower filter belt, in the process with the strainer operation, leans on gravity that remaining free-water is deviate from as much as possible.
The filter-press dehydration process: the S shape of dehydration cylinder is furnished with and is beneficial to the water that press filtration comes out and flows out smoothly, be clamped in up and down mud between two strainers and be subjected to the squeeze that increases step by step and the effect of shearing force in the filter-press dehydration district repeatedly, make the free-water of mud, interstitial water be come out by press filtration as much as possible.
In sum, the utility model is can make moisture percentage in sewage sludge drop to minimum and form the integrated machine equipment of a kind of simple and effective of mud cake, has the advantage of more efficient grade than existing single type water extracter on the market.
