Sewage sludge secondary deep dewatering method flow is:
1) mud, after preliminary hydro-extraction enters into storage bin, opens charging aperture, and is pushed in press filtration chamber by storage bin, keeps feed inlet and outlet to be in closed condition and thinks that press filtration is prepared;
2), by extruding transmission system drive the first toggle link and the second toggle link, the first toggle link and the second toggle link exert a force respectively to the stripper plate of two sub-devices of deep dehydration, start to carry out press filtration to mud, are discharged by moisture by drainage mechanism in press filtration chamber;
3), dehydration after, open feed inlet and outlet, the mud cake in press filtration chamber pushed out
In step 2) after, along with the carrying out of compression, now the void ratio of mud is very little, and the passage of moisture circulation is by sludge blockage, and not easily cloth is discharged after filtration, under the reverse drive of extruding transmission system, stripper plate returns to the reducer place, local of cylindrical shell, and second place sensor detects stripper plate, and controller sends signal to stripper plate rotary cylinder, cylinder is to stripper plate turning moment, and stripper plate rotates an angle; Hydraulic motor rotates forward again, drives stripper plate to carry out secondary extrusion, when stripper plate is pushed to extreme position to the mud of press filtration again, now the enlarge-effect of power is maximum, carry out pressurize, continued, until do not have moisture out the super-pressure press filtration regular hour to mud.
For the cleaning of drainage mechanism, moisture is closed the valve on drainpipe, is opened air inlet pipe valve after discharging from discharging tube, connects high-pressure air source, rinses the mud granule of aperture clogs on filter cloth and bottom plate.
Specific works principle is as follows:
Entering into through the mud of preliminary hydro-extraction moisture content higher (about 80%) enters in auger conveyor by feed hopper, under auger conveyor conveying, two mud in left and right enter into equal equivalent in the discharging bin of two sub-devices of deep dehydration, after accumulation after a while, charging flashboard is opened by flashboard cylinder operation, and discharging flashboard cuts out, and mud enters into press filtration chamber under gravity, when the mud in storage bin all enters into behind press filtration chamber, charging flashboard cuts out.Hydraulic motor is started working, hydraulic motor rotates forward and drives first gear, pinion, second largest gear, set square (one of draw back plate), toggle link (comprising the first toggle link and the second toggle link), power is sent on stripper plate, in the incipient stage of compression, because the void ratio of mud is comparatively large, the power required for compression is also less, but compression speed is very fast, now the transmission system of power mainly plays the effect of crushing failure at high speed, and extruding force is less.Along with the carrying out of extruding, mud is more and more real by what compress, void ratio diminishes, now required compression stress is increasing, and compression displacement is more and more less, and set square and toggle link are in the amplification position of a power, the enlarge-effect of power starts to manifest, only need the power that hydraulic motor is certain, through large pinion two-stage engagement and set square, toggle link power multiple amplification under, form huge extruding force at stripper plate place and press filtration carried out to mud.When being compressed to rear half stage, now the void ratio of mud is very little, the passage of moisture circulation is by sludge blockage, not easily cloth is discharged after filtration, hydraulic motor is reversed, at large pinion, set square, under the driving of toggle link, stripper plate returns to the reducer place, local of cylindrical shell, second place sensor detects stripper plate, controller sends signal to stripper plate rotary cylinder, cylinder is to stripper plate turning moment, after stripper plate rotates an angle, hydraulic motor rotates forward, again stripper plate is driven to carry out secondary extrusion to the mud of press filtration again, now, " duck eye " that pin during first time extruding is formed is supplied to water of compaction circulation passage, water of compaction easily passes through this passage through filter cloth, aperture enters flow channel for liquids, this stage is the packing stage of power, now right toggle link, set square, under state that left toggle link is in " stretching ", the enlarge-effect of extruding force transmission system power is maximum, pressure suffered by mud is also maximum, carry out pressurize certain hour, moisture in mud is constantly extruded, until do not have moisture to extrude, press filtration stops.Discharging flashboard is opened, and mud discharges press filtration chamber under gravity.The moisture be press-filtered out enters into fluid passage by the aperture on filter cloth, fixed base plate, and under check valve effect, this liquid can only from the unidirectional discharge of discharging tube.After running after a while, as the mesh of mud granule by filter cloth or the aperture clogs of fixed head, the controlled valve now opening high-pressure air source and air inlet pipe is opened, the controlled valve at drainpipe place is closed, and the mud granule blocked on filter cloth and on bottom plate aperture is rinsed well by gases at high pressure.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change.In a word, all various changes done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
