The working procedure of flexible tube presser:

The charging of filter element is filtered: a folded filter element is arranged in the pressure-bearing frame of frame, utilize raw material pumping installations that raw material is transported to one in pressurized filter element, wet mud raw material is under high pressure by the filter chamber bulging of screen pipe unit, adjacent porous disc is because the effect of elastomeric pad produces substantially equal gap, wet mud is clamp-oned in all gaps of opening, when sending, the stroke sensor of any one monitoring point of filter chamber squeezing cake thickness testing agency fills while putting in place, charging stop valve is closed, if the displacement of monitoring point, left and right is still short of, open the wet mud of corresponding auxiliary charging stop valve utilization and carry out part filling, make the local bulging that continues in screen pipe unit, after meeting filter chamber thickness and the depth of parallelism and requiring, all charging stop valves of this filter element are closed, this filter element transfers pressurized filter element to.

The filtration squeezing of filter element: again all the other a part of filter elements are filled to wet mud to its filter chamber successively as the filter element of exerting pressure, at filter element or pressure-bearing device, the sensor that detects filter chamber pressure is set, in the time that the pressure in filter chamber reaches first setting value, stop carrying and carry out pressurize, work as pressure decreased, or the dwell time finishes to continue to fill wet mud to its filter chamber, sending this filter element when any one monitoring point of filter chamber squeezing cake thickness testing agency fills while putting in place, charging stop valve is closed, if the displacement of monitoring point, left and right is not in place, opening the wet mud of corresponding auxiliary charging stop valve utilization fills, after meeting filter chamber thickness and depth of parallelism requirement, all charging stop valves of this filter element are closed, now this filter element is about to transfer to pressurized filter element, in this circulation, do not recharge wet mud, if pressurized filter element filter chamber internal pressure is inadequate in the pressure-bearing frame of frame, fill wet mud to other filter chamber as the filter element of exerting pressure successively and continue to provide expansive force, all must guarantee each conduct exert pressure filter chamber thickness and the depth of parallelism requirement of filter element in any process of once filling filter element.

Because exert pressure filter element and pressurized filter element are at work all in dewatering state, if raw material is very easy to dehydration, can consider temporarily the cleaner liquid control valve as the porous disc of the filter element of exerting pressure to close, outstanding its function of exerting pressure, make major part cleaner liquid temporarily rest on the core of porous disc, slow down the filter element of exerting pressure and become the speed of suppressing, guarantee the squeezing time of pressurized filter element, transferring the unlatching of pressurized filter element at it has closing valve, utilizes the core cleaner liquid of compressed air or vavuum pump Accelerating Removal porous disc; If raw material is not easy dehydration, meet after filter chamber thickness and the depth of parallelism require and immediately the cleaner liquid control valve of the porous disc of this filter element is opened, transfer pressurized filter element to.

When squeezing pressurized filter element, the coated filter cloth of inwall that a series of cushions of the filter chamber front and back position limiting structure of the front and back plane of the porous disc in the middle of screen pipe unit head on filter cloth and filter chamber contacts, the coated filter cloth that a series of cushions between every layer of porous disc head on filter cloth and adjacent porous disc contacts, in the filter chamber of the screen pipe unit of filter element, raw material is filled in around each porous disc; Open after air shut-off valve, filtrate sees through the filter cloth of screen pipe unit and the sieve aperture of all tubulose filtering mediums, along the sieve aperture of tubulose rigid filaments braiding conveyer belt and muscles and bones axially conflux and under; Simultaneously filtrate sees through the micropore of the filter cloth of porous disc, along the sieve aperture of tabular rigid filaments braiding conveyer belt and muscles and bones axially conflux and under, solid phase is stayed filter chamber; Can pump into the compressed air lower than squeeze force, intermittently or continuously import cleaner liquid is wherein imported manifold trunk by porous disc core assembly and extrude from drainage duct and drainage duct mouth from the mouth of pipe with the compressed air of lower pressure; Also can open vavuum pump, allow cleaner liquid enter filtering liquid bath.

When the expansive force of the filter element of exerting pressure makes to be clamped in excircle extruding more flat of the screen pipe unit of the pressurized filter element between pressing plate and bearing plate, filter the gap, front and back of indoor multilayer porous disc along with the compression of cushion diminishes simultaneously, thereby make the principle that chamber space diminishes complete Separation of Solid and Liquid; Although the filter chamber upper axial end portion of filter element can not be shriveled by compacted assembly by the constraint of upper flange, but the filter pulp of the axial epimere of filter chamber is wherein also because the mobility of filter pulp obtains and the filter pulp pressure in the axial stage casing of filter chamber is basic identical, after the part filter residue pressurized in the axial stage casing of filter chamber, may partly enter upper axial end portion and push the wetter filter pulp of having deposited, filtrate continuation sees through the hole of whole tubulose filtering medium and tabular filtering medium and discharges, and filter residue is trapped in filter chamber.

The deslagging of filter element: when pressurized filter element under high pressure guarantees after enough dewatering times, open the deslagging stop valve of this pressurized filter element, continue to open successively filter element and provide squeeze force as the filter element of exerting pressure, the filter Indoor Dry mud of this pressurized filter element is clamp-oned dry mud main road by the utilization filter element of exerting pressure, after getting rid of dry mud, close deslagging stop valve, this filter element changes into as the filter element of exerting pressure that sorts successively; Restart the next press dewatering work period.

Whole working procedure adopts PLC programme-control, can accomplish unmanned.When larger for treatment scale, can be by the filter element composition filter assemblies of some, each filter assemblies is still carried out the working procedure of above-mentioned filter element.

This equipment is applicable to the more mud of organic portion, and for example, the mud of sewage treatment plant general organic matter after over dry accounts for 50% left and right, and this mud is fine and smooth especially, not containing hard branch.Because the filter chamber thickness of this filter element can be zero, for not stopping up the good filter cake of filter cloth and mobility, all can utilize direct extrusion molding to discharge filter cake from the sealing lip of the slag-drip opening of screen pipe unit, do not walk the shake deslagging stage in the working procedure of sheet frame (barrier film) filter of aforementioned patent and prior art, the rolling-type dewaterer of the similar market sale of filter chamber slag-drip opening of this equipment control go out port strobe, because this equipment filter area is many greatly, although the edge of filter chamber may residual a small amount of dehydrated sludge cake again after filter chamber discharging mud cake, but production efficiency still compares rolling-type dewaterer to be improved greatly, in filter chamber, residual a small amount of dehydrated sludge cake adopts regular cleaning method to remove.

2, adopt screen pipe unit increase porous disc, even if filter area increases greatly, but sealing problem well avoided, be applicable to thin layer press filtration, the moisture of filter cake is reduced greatly; Relatively plate and frame filter press and band filter are for the energy consumption minimization of filter chamber sealing; For unloading relatively sheet frame (barrier film) the filter press much less of time of filter cake, improve filter efficiency;

3, the manufacturing process of porous disc is simple, make efficiency improves and the cost of unit filter area reduces greatly, and equipment total cost reduces; The installation of porous disc, safeguards simply, changes consumable accessory filter cloth easy, changes the filter cloth time short;

4, the filter cloth of filter element improves service life, and running cost reduces;

5, filter element designs simplification, thus the metal consumption of processed in units amount is reduced, and what be more conducive to that filter element does is very tall and big, produces thereby realize ultra-large processing scale;

6, when filter cloth damages, only single area is changed, thereby the consumption of having saved time and filter cloth is reused for stopping up after not serious damaged filter cloth can glue benefit;

7, utilize the stressed of filter element and the role's that exerts pressure the squeezing that converts filter element filter chamber Raw, squeeze force directly utilizes the pressure of pump in stock, feedstock pump pressurization pressure per ton is at 1Mpa, only need to consume 0.5Kw.h, the dry mud cake mud per ton that is 60% by the wet mud dehydration of moisture content 80% needs consuming electric power 1Kw.h; And other high-pressure compressing machine, the dry mud cake squeezing consuming electric power that is 80% by the wet mud dehydration of moisture content 97% just arrives 3-8Kw.h.Because this FU processing energy consumption is near or below belt filter, running cost reduces greatly.

8, powerful extruding spoil disposal method is particularly suitable for follow-up direct supercharging pumping, omits conventional belt and carries or shaftless helical feed and energy consumption thereof; Suitable continuous drying process need to be to the situation of mud cake extrusion material distributing machine, utilizes brute force extruding spoil disposal method and the supercharging pumping of flexible tube filter press, directly forms lath-shaped mud, omits the Special Equipment of extrusion material distributing machine.
