Filter press among above-mentioned the 1st embodiment is discharged guide member and is constituted as the filter cloth 5,5 of above-mentioned supporting part by the filtrate of discharging leader as above-mentioned filtrate.That is to say that as Fig. 2, shown in Figure 3, between adjacent filter plate 2,2, a pair of filter cloth 5,5 is housed, each filter plate 2 is square plate substantially, its peripheral edge portion is equipped with dimetric framework 1; On the other hand, in the inside of framework 1, filtrate is housed discharges guide member 3, this member 3 is the members that separate with framework 1, and with filter cloth 5 as supporting part.
It is foursquare plates that filtrate in the above-mentioned filter plate 2 is discharged guide member 3, and it is made by materials such as synthetic resin such as metal such as aluminium, iron or polypropylene, nylon, polystyrene or timber.When the gauge ratio of the inner edge of framework 1 is taken as 1, the gauge that this filtrate is discharged guide member 3 is about 1～1/5 than then, this filtrate is discharged the outer rim geomery of guide member 3 or roughly the same with the inner edge geomery of above-mentioned framework 1, perhaps it outer fringe surface and the inner peripheral surface of framework between leave certain clearance; In addition, also on this filtrate is discharged the surface of guide member, be provided with a plurality of filtrate flow through hole 3b ..., 3b, simultaneously crooked at an upper portion thereof outstanding part 1d place penetratingly offers stoste supply port 3a.
Above-mentioned filter cloth the 5, the 5th is the same with former known structure, promptly as shown in Figure 4, top at a pair of filter cloth 5,5, offering stoste supply port 5a respectively, the marginal portion of this stoste supply port 5a is sewed up mutually with each end that the stoste of tubular is supplied with the connected component 5b of usefulness respectively, and the stoste of this tubular is supplied with connected component and used with filter cloth 5 identical materials and make.In the upper end of each filter cloth 5, its end Zhe Xia And is sewed up, forms the cylindric bag 5c of portion, filter cloth hangs excellent 6 and just interts in this cylindric bag 5c of portion.Each filter cloth hangs rod 6 two ends by the spring 10,10 as the filter cloth vibration means, can joltily be hung on the pin 9, and this pin 9 is each top of passing above-mentioned a pair of bar 7,7.Make the above-mentioned tubular connected component 5b of filter cloth 5 penetrate above-mentioned filtrate and discharge among the stoste supply port 3a on the guide member 3, thereby make this tubular connected component 5b play the effect of connector, make filtrate discharge guide member 3 hanging with paralleling with filter cloth.As shown in Figure 5, the end portion that this filtrate is discharged guide member 3 is to utilize latch 2a, 2a on the bottom that removably is inserted in framework 1 inboard to locate, and it can not rocked on the thickness direction of framework 1.
Filter press with said structure, each filter plate 2 saidly assembles like that by following on it.Promptly, earlier the filter cloth 5 on one side in the filter cloth 5,5 is rolled, just launch after passing the stoste supply port 3a on the filtrate discharge guide member 3, the two sides that makes filtrate discharge guide member 3 is all covered by filter cloth 5,5, simultaneously, make tubular connected component 5b on the filter cloth 5 be positioned at filtrate and discharge stoste supply port 3a on the guide member 3, then filtrate is discharged guide member 3 and be lifted on the filter cloth 5,5.After this, utilize each handle 4 that framework 1 is lifted on each curb girder 12, make filter cloth 5 on one side penetrate this framework 1, And in the filtrate discharge guide member 3 embedding frameworks 1 that lifted by filter cloth 5,5 is fixed on the position of framework 1 bottom with the bottom that latch 2a, 2a discharge guide member 3 to filtrate, it can not rocked; On the other hand, each filter cloth is hung among the excellent 6 cylindric bag 5c of portion that insert on each filter clothes 5, the two ends of above-mentioned each filter cloth being hung rod 6 are lifted on the bar 7,7 by spring 10,10, thereby constitute the filter plate 2 that is formed an integral body by filtrate discharge guide member 3 and framework 1.Then, more a plurality of above-mentioned filter plates 2 are assemblied in the filter press.Movable platen 36 is advanced, make each filter plate 2 as two filter plates 2,2 on right side among Fig. 5, be the frame state that closes, meanwhile, stoste delivered to from each stoste supply port 3a ， And filters each filter chamber 13 of in pairs 5,5 formation of filter cloth in this filter chamber 13.At this moment, owing to be filter cloth 5,5 peripheral edge portion is clipped in framework 1, between 1, even filter pressure acts on filtrate and discharges on the guide member 3, also still it is connected the filter cloth 5 that is bearing in both sides, framework 1 front and back by tubular connected component 5b, on 5, therefore, even discharging guide member 3, filtrate with respect to framework 1 moving along thickness direction (being the fore-and-aft direction of filter press) taken place, it also can be subjected to being positioned at opposite one side with moving direction filter cloth 5 since filtrate discharge the traction of guide member 3 and filtrate discharged the effect that guide member 3 is returned to original position, the result, filtrate is discharged guide member 3 and is not almost moved, thereby can discharge guide member 3 adjacent filtrate, a pair of filter cloth 5 between 3,5 are positively filtered.On the other hand, under the driving effect that makes movable platen 36 at drive unit 29, retreat, thereby when making each filter plate 2 as two filter plates 2,2 in Fig. 5 left side, be out the frame state, the bar 7,7 of above-mentioned filter plate both sides also opens And thereupon and is opened into right filter cloth 5,5, and the filter residue 14 that is clipped between two blocks of filter clothes 5,5 is fallen.After this, when carrying out the preparation of the filtration operation second time, if necessary, then can be still under the state on the curb girder 12,12 at framework 1, only filtrate is discharged guide member 3 and taken off, change desired filtrate and discharged guide member 3 just from framework 1 and filter cloth 5,5.
When adopting the structure of the 1st above-mentioned embodiment, if want character and state according to filter liquide, change is discharged the size that filtrate on guide member 3 and the adjacent filter plate 2 is discharged the filter chamber 13 that forms between the guide member 3 the filtrate on the filter plate 2, framework 1 still can be contained on the filter press motionless, as long as take off latch 2a, 2a from framework, take off filtrate from framework then and discharge guide member 3, the filtrate that gauge is different is discharged guide member 3 embedding frameworks 1 interior And and is fixed with latch 2a, 2a, just can change the size of filter chamber 13 simply.That is to say that this structure has been simplified the replacing operation of filtrate discharge guide member 3 greatly.In addition, if want character and state according to filtrate, change filtrate discharge on the guide member 3 by through hole 3b ..., the filtrate stream that constitutes of 3b groove shape or width size, also as long as the groove shape of filtrate stream or the different filtrate of width size are discharged in the guide member 3 embedding frameworks 1, And is fixed just passable with latch 2a, 2a.In addition, framework 1 is discharged guide member 3 with filtrate and can be adopted different materials to make, and promptly framework 1 can adopt the material of good rigidly, and filtrate is discharged guide member 3 then can adopt the material that is suitable for stoste character and state most.If select for use than framework 1 lighter material and make filtrate discharge guide member 3, the weight of whole filter plate is alleviated, And can reduce the driving force of the drive unit 29 of mobile filter plate 2.Owing to can discharge guide member 3 to filtrate and separate, thereby be convenient to the carrying ， And of filter plate 2 and when filtrate was discharged guide member 3 damages, it was just passable only to change filtrate discharge guide member 3 with framework 1.Because a pair of filter cloth 5,5 that is positioned at framework 1 both sides filtrate from two-side supporting and discharged guide member 3, therefore, even the one side that filtrate is discharged guide member 3 when filtering is subjected to bigger active force, filtrate is discharged guide member 3 and also can not moved on thickness direction.Thereby guaranteed to filter at 5,5 of a pair of filter clothes that filtrate is discharged between the guide member 3,3 infalliblely.On the other hand, because it is not directly to be bearing on the framework 1 that filtrate is discharged guide member 3, therefore with regard to not needing to discharge guide member framework 1 is processed specially for supporting filtrate, can discharge guide member 3 with the filtrate of same model again embeds in the framework 1 of various models, like this, just enlarged the applicability of member.
And of the present invention is not limited to the 1st above-mentioned embodiment, and it can be implemented with other various types.For example, also can be, as shown in Figure 7 as Fig. 6, filter cloth hangs rod 6 and can not be installed on the handle 4, and is mounted on each lateral margin of top of the framework 1 on the filter plate 2.That is to say, make position adjustment rod 22 protrude in each lateral margin of top of framework 1, filter cloth hangs rod 6 and hangs excellent fixture 20 by filter cloth and be installed in above-mentioned position and adjust on the rod 22, and, hang between excellent fixture 20 and the framework upper surface at above-mentioned filter cloth, be equiped with to compression spring 21 as the filter cloth oscillating component.
In addition, also can be as Fig. 8, Fig. 9, as shown in Figure 10, on the position that filter cloth 27,27 is faced, be sewed with shield 5e, 5e And and the connector 5d that makes with rope or thin wire all be housed on above-mentioned shield 5e, 5e, and stoste supply port 3a is located on the corner portions of framework 1.On filtrate discharge guide member 3, offer rectangular connector jack 3c, above-mentioned connector 5d, 5d are inserted in this connecting hole 3c.The mutual coil buckling of connector 5d, 5d is got up just can discharge guide member 3 to filtrate and be lifted on the filter cloth 27,27.In addition, can also alternately constitute compound filter press to this compound filter plate 2 and former filter frame 25.Also have, 23 among Fig. 9 is the blocks that are used for adjusting spring 21 elastic force.
Above-mentioned filtrate is discharged guide member 3 and framework 1 can also be done circular respectively or other shapes.Filtrate is discharged guide member 3 except being provided with the sort of style of through hole 3b, also can be with concavo-convex groove or honeycomb shape.Discharge guide member 3 rocking in order to prevent filtrate with respect to framework 1, also can not use pin, but when filtrate being discharged guide member 3 embedding frameworks 1, utilize the embedding of two members 1,3 to cooperate, make filtrate discharge guide member 3 rocking with respect to framework 1 do not taken place.Can also work as filtration pressure and be increased to 2～5Kg/Cm
2During the left and right sides, discharge adjacent filtrate between the opposite face of guide member 3,3, folder advances protrusion, like this, although filtration pressure increases, also can dock mutually and avoids filtrate to discharge guide member 3 deviating from from framework 1 owing to protrusion.In addition, both can penetrate filtrate to the tubular connected component 5b on the filter cloth 5 or connector 5d and discharge through hole 3b on the guide member 3, be bearing on the filter cloth 5 thereby filtrate is discharged guide member 3; Also can discharge on the guide member 3 and form projection ， And above-mentioned connector 5d is connected on this projection, thereby above-mentioned filtrate discharge guide member is lifted on the filter cloth 5,5 filtrate.
As shown in figure 11, can also not make filtrate discharge guide member 3 hang rod 6 by filter cloth 5 and filter cloth is bearing on the framework 1, hang rod 6,6 but make filtrate discharge guide member 3 by filter cloth 5,5 and filter cloth, being bearing in filter cloth hangs on the excellent supporting member 33, this filter cloth hangs excellent supporting member 33 and is bearing on the guide rail 32 with can move freely, and this guide rail 32 is on the upper position that is erected between the forward and backward support 30,31.That is to say, filter cloth is hung the bottom that rod 6 is bearing in supporting member 33 swingably by spring 35, when framework 1 when curb girder 12 moves, meanwhile, filter cloth hang excellent supporting member 33 also roller 34 on guide rail 32, move, thereby open or close filter plate 2.
The filter press of the 2nd above-mentioned embodiment by the member of the maintenance filter cloth Jian Jian Ge And double as filter cloth vibration of discharging leader as above-mentioned filtrate, and is formed as the filter cloth 40,48 of supporting part.That is to say, such as shown in Figure 12 and Figure 13, in this 2nd embodiment, the filter plate 2 of filter press is equipped with dimetric framework 1 and keeps the member 41 of filter cloth Jian Jian Ge And double as filter cloth vibration, wherein dimetric framework 1 all hangs with laminar filter cloth 40A, 40B on two faces of the fore-and-aft direction of filter press, keeping the member 41 of filter cloth Jian Jian Ge And double as filter cloth vibration then is to be embedded in framework 1 interior De ， And between filter cloth 40A and 40B.Filter plate 2 uses filter cloth 40 as the supporting part that above-mentioned member 41 is bearing on the framework 1.
The big I of above-mentioned filter cloth 40 all covers the front and back of framework 1, is provided with stoste supply port 40a on its center, and this stoste supply port 40a is arranged in the space 1e And that is surrounded by framework 1 and is on the position of approximate centre.Clip framework 1 And and be suspended on filter cloth 40A, 40B on its front-back, stoste supply port 40a vis-a-vis, the peripheral part of 40a are sewed up connection mutually, form stoste supply port coupling part 40b, on the 40b of this coupling part, embed the member 41 of above-mentioned maintenance filter cloth Jian Jian Ge And double as filter cloth vibration.When clamping filter plate, the outer peripheral edge portion of the filter cloth 40,40 that lifts between the opposite face of adjacent frame 1 is clamped closely by framework 1,1, thereby two blocks of filter clothes 40,40 are closed, at 40,40 formation filter chambers 13 of two filter clothes.
Because the structure of the framework 1 on the above-mentioned filter plate 2 is identical with framework 1 among above-mentioned the 1st embodiment basically, therefore, identical part has just also dispensed its explanation with identical symbology ， And, here only to different structure division do one explanations.That is, on the upper end hinge 8 of each bar 7 of framework 1, form outstanding spring-loaded member 8a along the width of this filter press, this supporting member 8a is fixed up the upper end of spring 10, and is fixing filter cloth boatswain chair 42 at the end portion of spring 10.This filter cloth boatswain chair 42 has a pair of aperture 42a, 42a, and the filter cloth of each filter cloth 40 hangs rod 6 end and all is inserted in each aperture 42a and fixes.Therefore, filter cloth 40A, the 40B that this framework 1 Jia lives in And is played on the two sides, front and back of framework 1 hangs rod 6,6 by filter cloth respectively, lifted by the filter cloth boatswain chair 42,42 of adjacency.
The member 41 of the maintenance filter cloth Jian Jian Ge And double as filter cloth vibration on the above-mentioned filter plate 2 is such shown in each figure in Figure 14 (I)～(III), basically the thin plate by circle constitutes, the connector 41c that inboard annulus 41a and outside annulus 41b are provided with by 90 degree of being separated by ..., 41c connects into an integral body.On the surface of this member 41, form the general rib 41d of a plurality of filtrate flows ..., 41d.Offering hole 41e at the middle part of above-mentioned inboard annulus 41a, its size basically with above-mentioned filter cloth 40 on the identical ， And of stoste supply port 40a be enclosed within the outside of the stoste supply port coupling part 40b of above-mentioned filter cloth 40.That is to say, a filter cloth 40 is rolled, then above-mentioned member 41, by the hole 41e among its inboard annulus 41a, the coupling part 40b Shang ， And that is enclosed between filter cloth 40A and the 40B lifts both sides filter cloth 40A, 40B as described above, like this, just the space 1e Li ， And of member supporting in framework 1 of this maintenance filter cloth Jian Jian Ge And double as filter cloth vibration roughly is on the center.Because above-mentioned member 41 is bearing on the filter cloth 40,40, therefore in framework 1, just form two space S
1, S
2, i.e. the space S that between the outer circumference surface of the medial surface of framework 1 and outside annulus 41b, forms
1, and the space S that between this outside annulus 41b and inboard annulus 41a, forms
2These spaces S
1, S
2Just constitute filtrate and flowed out part.Therefore, even the member 41 that keeps the vibration of filter cloth Jian Jian Ge And double as filter cloth is bearing in the framework 1, also can not influence the discharge of filtrate.
By above-mentioned framework 1 and keep each filter plate 2 that the member 41 of filter cloth interbody spacer double as filter cloth vibration constitutes and each filter cloth 40 as Figure 12 and shown in, framework 1 is erected between fore-stock 30 and the movable platen 36 with can move freely Di And row, between adjacent frame 1,1, a pair of filter cloth 40,40 hangs rod 6, is lifted between the adjacent framework 1,1 by the spring 10,10 on each a pair of bar 7,7 and 7,7 of both sides of 1,1 of adjacent frame by filter cloth boatswain chair 42,42 and filter cloth; And and, keep the member 41 of filter cloth Jian Jian Ge And double as filter cloth vibration to be nested on the coupling part 40b of the stoste supply port on the filter cloth 40,40 that is positioned at framework 1 front and back, it places the space 1e of 1 li of framework again.In addition, in Figure 12,30a is the stoste ascending pipe, and it is to be connected with each filter chamber 13 by above-mentioned stoste supply port 40a.
When adopting above-mentioned structure to filter, make above-mentioned movable platen 36 to fore-stock 30 1 side shiftings earlier, filter plate 2,2 is abutted against on the side of fore-stock (referring to Fig. 1), then former fluid supply pump (not shown) is connected to above-mentioned stoste ascending pipe 30a and goes up And force feed stoste, make stoste by stoste supply port 40a high pressure packing in each filter chamber 13.So,, also will guarantee have certain interval therebetween by the member 41 that is located at the maintenance filter cloth Jian Jian Ge And double as filter cloth vibration in the middle of their although it is approaching mutually to clip the left and right sides filter cloth 40 and 40 of framework 1.Therefore, filtrate is passed through the space S of filter cloth 40,40 in framework 1 from filter chamber 13
1, S
2Flow out, and then wander the bottom of framework 1.And flows into filtrate recovery holes 1a from intercommunicating pore 1c and reclaims.On the other hand, 14 of filter residues are retained between the paired filter cloth 40,40.
After filter finishing, make movable platen 36 retreat ， And filter plate 2,2 is retreated, then the distance between the adjacent frame 1,1 enlarges, and promptly opens after the frame, and above-mentioned filter residue 14 just falls and discharges from the bottom of the filter chamber 13 opened.At this moment, because filter cloth the 40, the 40th is being lifted by spring 8,8, therefore when filter plate retreats, just be easy to vibrate, when the filter cloth 40 of vibration is run into the member 41 that keeps the vibration of filter cloth Jian Jian Ge And double as filter cloth, filter residue 14 shakes that stick on filter cloth 40 meshes fallen.
Adopt the 2nd above-mentioned embodiment, framework 1 is made simple square shape shape basically, therefore, but not only weight reduction, and can reduce cost.In addition, because the interval of 40,40 of filter clothes guarantees by the member 41 that keeps the vibration of filter cloth Jian Jian Ge And double as filter cloth, thereby just can prevent reliably that filter cloth 40,40 from combining; Because keep the member 41 of filter cloth Jian Jian Ge And double as filter cloth vibration to hang on filter cloth 40,, just prevented effectively that also the mesh of filter cloth 40 from stopping up when filter cloth 40 Zhen Dong And run into above-mentioned member 41 again so the filter residue that sticks on the filter cloth 40 is fallen.In addition, also because keep the member 41 of filter cloth Jian Jian Ge And double as filter cloth vibration not get in touch,, like this, simple and easy ， And is installed and can reduces number of components so can be installed in easily on the coupling part 40b of stoste supply port of filter cloth 40 with framework 1.Further say,, therefore, keep the situation of spacer member to compare, have various advantages such as the filter effect of raising with being provided with owing to keep the not influence of strainability of 41 pairs of filter clothes 40 of member of filter cloth Jian Jian Ge And double as filter cloth vibration.
The 2nd above-mentioned embodiment is not implemented by the restriction of above-mentioned record also can.For example also go for the squeeze type filter plate.Just as Figure 15, as shown in Figure 16, inboard at the filter cloth 40,40 that clips framework 1, overlapping and using that rubber one elastic-like material is made and the surface has a plurality of concavo-convex squeeze diaphragms 43, each top of a pair of squeeze diaphragm 43 of framework 1 front and back and each bottom respectively by bolt 44 ..., 44 and 44 ..., 44 interfix and simply install.Each stoste supply port 43a on the paired like this squeeze diaphragm 43,43 interconnects ， And the member 41 Qian Tao And that above-mentioned maintenance filter cloth Jian Jian Ge And double as filter cloth vibrates is bearing on this coupling part.In Figure 15,1f is the fluid circulating hole that is opened on the hanger 1b of framework 1, and fluid that squeeze diaphragm 43 expands is pressed into by intercommunicating pore 1g between vis-a-vis the squeeze diaphragm 43,43 from above-mentioned opening 1f.In addition, 43b, 43b are out the filtrate extraction aperture on squeeze diaphragm 43, on it leads to intercommunicating pore 1c on the framework 1 from the squeeze diaphragm surface.1h is provided in a side of the flushing liquor opening on the upside hanger 1b of framework 1, this opening 1h communicates with intercommunicating pore 1i on the framework 1 and the intercommunicating pore 43c on the squeeze diaphragm 43, after filtering end, flushing liquor is ejected on the inner face of squeeze diaphragm surface and filter cloth 40,40 by opening 1h, intercommunicating pore 1i, 43c.In the above-described embodiment, since facing to squeeze diaphragm 43,43 between be by member 41 maintenances that keep the vibration of filter cloth Jian Jian Ge And double as filter cloth at interval, therefore can prevent coinciding of barrier film 43,43 reliably, thereby be convenient to the supply of squeeze and filter fluid.In addition, by filter cloth 40 effects, can carry out squeeze and filter to filter residue 14, and when filter plate is opened frame, can strengthen the vibration of filter cloth 40 by squeeze diaphragm 43.

In the explanation of above-mentioned the 2nd embodiment, what narrate all is the stoste supply port 40a on filter cloth 40, the 48a, the locational pattern of substantial middle that 48b is positioned at framework 1, but the present invention also is applicable to the so-called top feed formula (referring to Fig. 2) that the stoste supply port is arranged on framework 1 top, and the device that the raw material supplying mouth is arranged on the so-called bottom feed formula of framework 1 bottom.The hanging method of each filter cloth 40,48a also is not limited to these above-mentioned methods, also can except with the framework, use other member instead and support lifting as shown in Figure 11.In addition, the shape of framework 1 also can be a shape arbitrarily such as circle or polygonal.
Filter press among above-mentioned the 3rd embodiment reclaims member by the filtrate of discharging leader as above-mentioned filtrate, and constitutes as the filter cloth 53 of supporting part.Promptly, the filter plate 2 of the filter press among the 3rd embodiment as Figure 26, as shown in Figure 27, it have framework 1 and be contained in that filtrate in this framework 1 is reclaimed member 52 ， And with can move freely and filter cloth 53,53 as supporting part.This filter cloth 53,53 is provided on two sides on the thickness direction of above-mentioned filter plate 2, surrounded the space 1e in the framework 1, during filtration, a pair of filter cloth 53,53 is clipped between the adjacent frame 1,1, stoste is pressed in the filter chamber 13 between this filter cloth 53,53, filter, filter cake is remained in the filter chamber 13 between the filter cloth 53,53; On the other hand, filtrate is pooled to space 1e Li ， And in each framework 1 by each filter cloth 53 and it was passed above-mentioned filtrate reclaims member 52 and flow to the bottom of framework 1, thereby is recovered.
Said frame 1 is that the horizontal section and the vertical cross section of frame part is pentagonal member, and the inner surface of framework is to form inclined plane 1p, 1p along the thickness direction oblique And that inclines respectively from the mediad both sides.Each place, side in said frame 1 bottom forms hanger 1b, 1b respectively, on this hanger 1b, 1b, offering through hole along thickness direction, be the intercommunicating pore 1c that filtrate recovery holes 1a ， And and the space 1e that is forming in each corner of framework 1 bottom is being offered framework 1 and above-mentioned filtrate recovery holes 1a are connected.
Both sides (being the both sides of filter press fore-and-aft direction) the And that above-mentioned filter cloth 53 is contained in respectively on said frame 1 thickness direction is clipped in the space 1e that forms in the framework 1 wherein, clamp framework 1 a pair of filter cloth 53,53 the upper and lower respectively by bolt 54 ..., 54 be fixed on the framework 1.On the position of the middle body that is equivalent to framework 1, offering circular stoste supply port 53a, above-mentioned two blocks of filter clothes 53,53 are sewed up on the periphery of stoste supply port 53a mutually.
As shown in figure 29, it is to be made of cloth that above-mentioned filtrate is reclaimed member 52, places the space 1e of framework 1, and two sides is topped by filter cloth 53,53 respectively before and after it.Reclaim the middle body of member 52 above-mentioned filtrate and offering the intercommunicating pore 52a that is connected with the stoste supply port 53a on the filter cloth 53, the periphery of this intercommunicating pore 52a is sewed up mutually with the periphery of the stoste supply port 53a on the filter cloth 53, filtrate is reclaimed member 52 and is hung at filter cloth 53 Shang ， And and can freely move together with filter cloth 53.With regard to this filtrate is reclaimed the installation method of member 52 on filter cloth 53, if filtrate is reclaimed member 52 directly to be sewn on the filter cloth 53, because wherein the width of mesh of the filter cloth 53 of sutured portion is unlike the mesh of other parts uniformity so, so filter effect is reduced.And be that the periphery that like that periphery of the stoste supply port 53a on the filter cloth 53 and filtrate is reclaimed the through hole 52a on the member 52 is as mentioned above sewed up mutually in the present invention, therefore just can not influence the width of mesh of above-mentioned filter cloth 53, just can not reduce filter effect yet.Above-mentioned filtrate is reclaimed member 52 and is preferably adopted hard a little any material to make, and like this, though it only depends on the periphery of through hole 52a to be fixed, Bu And also can make filtrate recovery member 52 entirely be fixed up in framework 1 without any supporting Shang it.The material that filtrate is reclaimed member 52 can be any materials such as natural material, synthetic resin or metal, but preferably lighter.When making, also can do reticulating of synthetic resin or metal.The front shape that above-mentioned filtrate is reclaimed member 52 is dimetric, but also can make arbitrary shapes such as circle or triangle not limitedly.Should form certain interval between the medial surface 1p of outer rim with framework 1 of filtrate recovery member 52.
As Figure 29, as shown in Figure 30, reclaim the through hole 52a top on every side of member 52 above-mentioned filtrate, installing the member 55 that keeps the gap, be used for remaining on the gap that has certain intervals between the filter cloth 53,53 on the framework 1, making filtrate enter the inboard of framework 1 easily from filter cloth 53.This maintenance clearance component 55 makes the bossing 55b on its chorista 55a on one side pass filtrate and reclaims in the hole 55d of hole 52b ， And intercalation on another side chorista 55c on the member 52, reclaims on the member 52 thereby be fixedly mounted in filtrate.
Adopt the filter press of said structure followingly to act on like that.The press filtration plate 2 that each is above-mentioned ..., 2 each can before and after be lifted on the curb girder 12,12 with moving freely, this curb girder the 12, the 12nd is erected on the both sides of (referring to the 1st figure) between the forward and backward support 30,31 of filter press; By advancing of movable platen 36, promote a plurality of filter plates 2 ..., 2 be close to fore-stock, then, the stoste supply port 53a of the filter cloth 53 of stoste from each filter plate 2 is pressed into the filter chamber 13 that forms between the aspectant a pair of filter cloth 53,53, stoste is filtered on each filter cloth 53, thereby is separated into filter residue 14 and filtrate.Filter residue 14 is retained in 13 li of filter chambers between the paired filter cloth 53,53, and filtrate is then reclaimed the member directed stream downwards by the inside ， And that each filter cloth 53 enters framework 1 by filtrate, flows into the filtrate recovery holes 1a from the intercommunicating pore 1c of framework 1 bottom and is reclaimed.
Adopt above-mentioned the 3rd embodiment, filtrate is not set in the framework 1 of filter plate 2 fully discharges guide member, and only be that the cloth that will reclaim member 52 as filtrate is lifted on the filter cloth 53, therefore, compared with the in the past the sort of mode that filtrate discharge guide member is set in framework 1, alleviated weight greatly.Again owing to filtrate reclaimed member be installed in the framework 1 between the filter cloth 53,53, thus can guarantee to flow into the filtrate of frameworks 1 inside from filter cloth 53, by filtrate reclaim member effect and along filtrate reclaim member 52 successfully Liu Xia And be retracted.In addition, because above-mentioned filtrate recovery member 52 is arranged to move freely with filter cloth 53, therefore, even when filtering, reclaim the two sides of member 52 just in case produce bigger filtration pressure difference filtrate, also can be cushioned absorption, thereby this member is not damaged because of moving of this member 52.That is to say to have filtrate and discharge the filter plate of leader to former, in case produce bigger pressure reduction, will to discharge leader be that rigid body makes it that the danger of damage be arranged owing to filtrate.In addition,, above-mentioned filtrate makes because reclaiming member 52 usefulness clothes, thereby easy strain, above-mentioned pressure reduction just can be absorbed by the strain of cloth itself.
The present invention the 3rd Shi Shi Li And is not limited to as above said form of implementation, can also implement with other various forms.For example, the thickness that above-mentioned filtrate is reclaimed member 52 can be arbitrarily, its area size also differs fixation as shown in Figure 26, at the medial surface 1p of framework 1 and the outer intermarginal certain intervals that leaves of filtrate recovery member 52, but can be as shown in figure 31 like that, make its medial surface 1p that expands to framework 1, perhaps make its medial surface 1p that crosses framework 1, bigger than framework 1.And and, also not necessarily one of its number, also can be shown in figure 32 like that with two or number arbitrarily.Here, Figure 32 is the side sectional view of embodiment shown in Figure 31.When filtrate when to reclaim member 52 be a plurality of, just in the 1e of the space of framework 1, produce the gap between the filter cloth 53,53 relatively easily, thereby just reclaim filtrate easily.Filtrate is reclaimed the mounting means of member 52 on filter cloth 53 also can be as shown in figure 31,57 ..., such places, four angles such as 57, perhaps on other positions, sew up fixing.Can also be as required, it is fixing to use shield to sew up, and this shield is sewn to filtrate recovery member 52 on the filter cloth 53 and uses.If filtrate is reclaimed member 52 and is made by elastomeric material, then when filtering, produce bigger filtration pressure difference even reclaim filtrate between the filtration pressure on two sides of member 52, also can be cushioned absorption by the distortion of itself; Even and filtrate recovery member is a rigid body, also can install it with respect to filter cloth 53 or framework 1 with moving freely, thereby when between the two-face filtering that above-mentioned filtrate is reclaimed member 53 is pressed, producing big pressure reduction, can reclaim moving of member 52 and it is absorbed by filtrate.In addition, the material that above-mentioned filtrate is reclaimed member 52 also not necessarily itself just has the hole that filtrate is passed through as cloth etc., and this member fully can be by the lamellar material that does not have the hole.
Also can install and keep clearance component 55 according to factors such as the character of the material character of filter cloth 53,53 and stoste and states.Keep clearance component 55 also can be not limited to form in the foregoing description, it can adopt arbitrarily shape, number ， And can be contained in arbitrarily on the position arbitrarily.For example, shown in Figure 33,34 like that, can a pair of annular plate 56e, 56e be disposed at filtrate reclaim through hole 52a on the member 52 around ， And by bolt 57 ..., 57 it is installed in filtrate reclaims on the member 52 and constitute and keep clearance component 55.Wherein each plate 56e is made up of the plate 56c, the 56d that roughly are the c font, and on the surface of each plate 56c, 56d, alternately form the negative area 56b and the bossing 56a that contacts usefulness that stoste is supplied with usefulness at interval, when a plurality of frameworks 1 ..., 1 push a side Zhi Jia And of filter press to when clamped by movable platen, keep bossing 56a, the 56a of clearance component 56 just to be in contact with one another, simultaneously, aspectant a pair of negative area 56b, 56b just form gap portion, and stoste is just supplied with filter chamber 13 from this gap portion.
Above-mentioned filter cloth 53 also can be made a bigger filter cloth as shown in Figure 20, lives the two sides, front and back of framework 1 is topped, simultaneously, also can be without framework 1, and with other members (referring to Figure 11) filter cloth 53 is lifted.The position of stoste supply port 53a on the filter cloth 53 is also not necessarily on the filtering surface in framework 1, can be arranged on beyond the filtering surface, can make top-feed formula or bottom feed formula.
In addition, the shape of above-mentioned filter plate 2 can also not necessarily be limited to dimetric, can be shape arbitrarily such as circle.
In the scheme of above-mentioned each embodiment and variation, be with filter cloth as supporting part, but also can use supporting member such as resilient rope as supporting part, filtrate discharged leader be installed in the framework 1 with can move freely.In addition, in the scheme explanation of the above embodiments and variation, same member is all represented with prosign basically, has omitted the explanation to it here.
