Description
Technical field
The present invention relates to a kind of plate and frame type filter-press filter cloth, more particularly to a kind of plate and frame type filter-press for Treatment of Sludge
Filter cloth.
Background technology
Plate and frame filter press is very ripe dehydration equipment, using many in sludge dewatering project.Plate and frame type filter-press will
Filter plate with filtrate path is parallel with filter frame to be alternately arranged, and every group of filter plate and filter frame are sandwiched between filter cloth, with compression end filter
Plate and filter frame compress, and make to form a press filtration room between filter plate and filter plate.Sludge flows into from charging aperture, and water is by filter plate from filtrate
Outlet discharge, mud cake are deposited on inframe filter cloth, are peeled off mud cake after filter plate and filter frame release.
Plate and frame type filter-press is mainly by fixed plate（Tailgate）, filter plate, filter cloth（Some groups）, pressure strip（Head plate）Filled with compressing
Composition is put, this principle seems simple, and still, existing structure is in practical operation but far from this way, because existing filter cloth is set
Timing only considers to filter, and filter cloth is arranged on filter plate, polylith filter plate, filter cloth arrangement, and pressure strip action is promoted by pressing device, but
Basic sealing does not live between filter plate and filter plate in work, causes a large amount of hydrojets.
Moreover, the known disadvantages as plate and frame type filter-press：Filter frame material inlet is easily blocked, and filter cake is not easily taken out, it is impossible to
Continuous operation, treating capacity is small, and operating pressure is low, not pressure-resistant, fragile plate, and filter cloth consumption is big, and sheet frame is difficult to accomplish unattended, filter
Cloth usually needs manual cleaning.
The content of the invention
The present invention can improve work compression resistance to solve the above problems, providing one kind, extend the filter cloth life-span, and with sealing effect
The plate and frame type filter-press filter cloth for Treatment of Sludge of fruit, the filter cloth are used so that filter frame material inlet is not easily blocked, filter cake pole
Easily remove and filter cloth will not be caused damaged.
The present invention is adopted the technical scheme that to reach above-mentioned purpose：A kind of plate and frame press filtration for Treatment of Sludge
Machine filter cloth, the installation sealing surface with filter plate is set in the surrounding of filter cloth, and installs in the filter cloth of sealing surface and immerse fluid sealant, filtering
The filtration fraction of cloth sets broken cake raised.
Further, the installation sealing surface immerses fluid sealant and referred to：Complete wetting in fiber cloth, and impregnation is uniform.
Further, the two-sided impregnation of installation sealing surface of the filter cloth, injecting glue coplanar flat is bright and clean, injecting glue height bilateral
Not higher than 0.5mm in filter cloth surface.
Further, the fluid sealant is curing fluorine glue.
Further, the broken cake projection is cone or the one or more combination of circular cone stage body or cylinder.
Further, the broken cake projection sets several in filter-cloth filtering part uniform intervals.
Further, the broken cake projection is cone.
The beneficial effects of the invention are as follows：Due to two-sided impregnation, injecting glue coplanar flat is bright and clean, serves the work of nature sealing
With, and during extruding, compacting is more and more uniform, and pressure is balanced so that filter frame material inlet is not easily blocked, separation of solid and liquid
Degree is high, filter cake good forming effect；Broken cake projection can puncture mud cake surface in extruding, and to allow moisture to separate out more thorough, and and can exists
During opening, mud cake is set to come off easily；The combination of said structure solves the problems, such as that existing filter press is present, and extends the filter cloth longevity
Life.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
In figure：1st, filter cloth, 11, installation sealing surface, 12, filtration fraction, 2, broken cake it is raised.
Embodiment
As shown in figure 1, a kind of plate and frame type filter-press filter cloth for Treatment of Sludge, in the surrounding setting of filter cloth 1 and filter plate
Installation sealing surface 11, and install in the filter cloth of sealing surface and immerse fluid sealant, set broken cake raised in the filtration fraction 12 of filter cloth
2。
The installation sealing surface 11 immerses fluid sealant and referred to：Complete wetting in fiber cloth, and impregnation is uniform.
Preferably, the 11 two-sided impregnation of installation sealing surface of the filter cloth 1, injecting glue coplanar flat is bright and clean, and injecting glue height is double
Side is not higher than 0.5mm in filter cloth surface.
Preferably, the fluid sealant is curing fluorine glue.
The broken cake projection 2 is cone or the one or more combination of circular cone stage body or cylinder.
The broken cake projection 2 sets several in the uniform intervals of filter-cloth filtering part 12.
Preferably, the broken cake projection 2 is cone.
As the use of fluid sealant, two ways impregnation and gluing can be used, gluing is that rubber cement is coated on into fabric
Surface, to obtain certain thickness glue-line.Impregnation is to immerse latex or rubber cement in fabric tissue, fabric fibre is enclosed glue
Layer.Because gluing simply makes fabric face apply glue-line, and filter cloth has a certain thickness, and moisture can still pass through filter cloth side in slurries
Along extravasation.Impregnation makes filter cloth surface and organization internal enclose fiber glue-line, it is possible to prevente effectively from the problem of gluing, it is therefore, excellent
Select impregnation.
Statement is needed exist for, for prior art, many people were not in contact with, and in the prior art, full wafer filter cloth is cut out
Shearing is segmented into finished product filter cloth, and filter cloth is sealing surface in itself（Due to the structure of its filtering, it is impossible to add sealant in centre, add
Adding can cause filtering can not carry out or be quickly damaged）, fabric external force plastic extruding deformation of originally experiencing is small, is not present again high-precision
Smooth surface is spent, so sealing is poor, when especially having the fine particle to be clipped in filter cloth sealing surface in mud, muddy water will give a tongue-lashing out.
Simultaneously as these problems, the filter frame material inlet brought is easily blocked, and filter cake is not easily taken out, it is impossible to continuous operation, treating capacity
Small, operating pressure is low, not pressure-resistant, fragile plate, and filter cloth consumption is big, and sheet frame is difficult to accomplish unattended, and filter cloth often needs artificial clear
Reason.
For the present invention due to two-sided impregnation, injecting glue coplanar flat is bright and clean, serves the effect of nature sealing, and in extruding
During, compacting is more and more uniform, and pressure is balanced so that filter frame material inlet is not easily blocked, and separation of solid and liquid degree is high, filter cake shaping
Effect is good；Broken cake projection can puncture mud cake surface in extruding makes moisture precipitation more thorough, and and can makes mud easily when opening
Cake comes off；The combination of said structure solves the problems, such as that existing filter press is present, and extends the filter cloth life-span.
The embodiment of the present application is only intended to illustrate technical characteristic disclosed in the present application, and those skilled in the art pass through simple
The change that is carried out of replacement, still fall within the scope that the application is protected.
