Deep dehydration method for sludge flow process is:
1) mud, after preliminary hydro-extraction enters into storage bin, opens opening for feed, and is pushed in press filtration chamber by storage bin, keeps feed inlet and outlet to be in closing condition and thinks that press filtration is prepared;
2), press filtration in earlier stage: actuating unit is started working, and drives its push rod to move downward, and to drive Double crank link mechanism kinematic, Double crank link mechanism urges stripper plate moves downward extruding mud;
3), the press filtration later stage: by the supercharging to actuating unit, significantly improve the dynamics of push rod, in conjunction with the effect of Double crank link mechanism, to the further high-pressure extrusion of mud; When stripper plate is pushed to limit position, state that crank connecting rod mechanism is in " stretching ", keeps the press filtration regular hour;
4), dehydration after, open feed inlet and outlet, the mud cake in press filtration chamber pushed out.
Specific works principle is as follows:
Mud through preliminary hydro-extraction water ratio higher (about 80%) enters in storage bin, after accumulation after a while, feeding cylinder promotes delivery sheet and the mud in storage bin is pushed to press filtration chamber, now, feeding gate plate is opened, and discharging flashboard cuts out.When the mud in storage bin all enters into behind press filtration chamber, feeding gate plate is also closed, stroke oil cylinder is started working, stroke oil cylinder pushes the work forward the push rod of oil cylinder, push rod promotes the pinblock of Double crank link mechanism, power is sent on stripper plate by short toggle link, little toggle link, long toggle link, side link by the power of pinblock, in the early stage of press filtration, because the void ratio of mud is larger, power required for compression is also less, but compression speed is very fast, and now the effect of crushing failure at high speed is mainly played by Double crank link mechanism, and squeeze is less.Along with the carrying out of press filtration, enter the press filtration later stage, mud is more and more real by what compress, void ratio diminishes, and now required force of compression is increasing, and compression displacement is more and more less, the scale effect of the power of Double crank link mechanism starts to manifest, namely only need the power that push rod is certain, after Double crank link mechanism amplifies, form huge squeeze at stripper plate place and press filtration is carried out to mud.Further could extrude mud owing to needing larger power, now stroke oil cylinder can be switched to pressurizing cylinder, by the supercharging of pressurizing cylinder, the initial forces acted on push rod also significantly improves, in conjunction with the scale effect of the power of Double crank link mechanism, under the dual amplification of the power of pressurizing cylinder and crank connecting rod mechanism, stripper plate can provide enough power to extrude mud.
Under the toggle of crank connecting rod mechanism " stretches " state, now the scale effect of crank connecting rod mechanism power is maximum, and the pressure suffered by mud is also maximum, now carries out pressurize certain hour, moisture in mud is constantly extruded, until do not have moisture to extrude, press filtration stops, and charging flashboard and discharging flashboard are opened simultaneously, seat advance and retreat oil cylinder and feeding oil cylinder work simultaneously, seat advance and retreat oil cylinder pushing feeding oil cylinder entirety is advanced, and feeding oil cylinder also works simultaneously, and the mud cake of compacting is pushed out discharge.The moisture be press-filtered out enters into fluid passage by the aperture on filter cloth, bottom plate, and under check valve effect, this liquid can only from the unidirectional discharge of collector tube.
After running certain hour operation, if the mesh of mud granule by filter cloth or the aperture clogs of bottom plate, the opening-closing valve then can opening high-pressure air source and inlet pipe is opened, the opening-closing valve at collector tube place is closed, and the mud granule blocked on filter cloth and on bottom plate aperture is rinsed well by high pressure gas.
When the sludge quantity change processed, if when the mud entering into press filtration chamber increases, after extruding, final hmc thickness will increase, stripper plate position will relatively on move, if now upper mounted plate is still in original position, Distance Shortened then between stripper plate and upper mounted plate, namely crank connecting rod mechanism is in " suppressing song " state, " can not stretch " scale effect of the power that then can have a strong impact on crank connecting rod mechanism.So, now by the effect of setting nut, upper mounted plate is moved corresponding distance on the net, ensure that the distance between stripper plate and upper mounted plate remains rational distance, crank connecting rod mechanism can be made to be in the state of " stretching ", to make crank connecting rod mechanism reach the scale effect of best power.
Below only just preferred embodiment of the present invention is described, but can not be interpreted as it is limitations on claims.The present invention 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 independent claim of the present invention are all in protection scope of the present invention.
