Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
Referring to Fig.1, a kind of slurries filtration device 100, including size barrel 10 and bung 20.Size barrel 10 includes bottom wall 11 and ring
Around the side wall 12 of bottom wall 11, bung 20 is suitable for being fixed at the top of side wall 12, surrounds slurry containment space with size barrel 10
100a.Wherein, bung 20 is equipped with feed inlet 20a, and feed inlet 20a is adapted to feed pipe 200, so that slurry to be filtered can
Enter slurry containment space 100a from the external world.Size barrel 10 is equipped with discharge port 11a, and discharge port 11a is adapted to discharge nozzle
300, so that filtered slurry can flow out to the external world from slurry containment space 100a, stamp and dyeing are carried out to cloth.
Specifically, discharge port 11a is arranged on bottom wall 11.Bung 20 is located at the top of slurries filtration device 100, and bottom wall 11
In the bottom of slurries filtration device 100.Feed inlet 20a is arranged on bung 20, discharge port 11a is arranged on bottom wall 11, enters
The slurry of slurry containment space 100a can facilitate the filtering of slurry under the effect of gravity to the flows of size barrel 10.
In the specific filter process of slurry, air driven pump can be also set, and air driven pump is suitable for will be to be filtered before discharge port 11a
Slurry is endlessly delivered in the 100a of slurry containment space.Specifically, air driven pump pressure value control in 0.2MPa hereinafter,
Excessive pressure is generated to avoid slurry containment space 100a.
With continued reference to Fig. 1, slurries filtration device 100 further includes the filter bag 30 being arranged in the 100a of slurry containment space, mistake
First mesh of the filter bag 30 with the opening 31 for being located at top and on 30 ontology of filter bag with suitable aperture (does not show in figure
Out), the first mesh is for being filtered slurry.The slurry for flowing into slurry containment space 100a takes the lead in flowing by opening 31
It in filter bag 30, and is flowed out outside filter bag 30 by the first mesh, the impurity such as solid particulate matter in slurry are because that can not pass through first
Mesh and be trapped in filter bag 30, to realize filtering to slurry.
However, inventor during slurries filtration, in the 100a of slurry containment space the study found that usually have biggish
Pressure, so that the slurry being located in filter bag 30 has biggish active force to filter bag 30.And general use of filter bag 30 has
The materials such as woven fabric are made, and can deform and increase the aperture of the first mesh under the active force of slurry.When the hole of the first mesh
After diameter increases, mixes the impurity in slurry and be then easier to flow to discharge port 11a by filter bag 30.Thus reduce slurry
The filter efficiency of filter 100.Also, when the pressure in the 100a of slurry containment space reaches a certain level, filter bag 30 because
Deformation is too big and can be destroyed, to can not effectively be filtered to slurry.
In the present embodiment, slurries filtration device 100 further includes the filter mantle 40 being arranged in the 100a of slurry containment space, filtering
Cover 40 is coated on the periphery of filter bag 30, to limit the maximum distortion shape of filter bag 30.That is, when filter bag 30 because
Pressure is larger and when deforming, the maximum distortion shape of filter bag 30 does not exceed the shape of filter mantle 40.Therefore, the first net
The aperture in hole can be defined in a certain range, not have too big increase, still be able to miscellaneous to particulate matter in slurry etc.
Matter is filtered, and is prevented outside impurity outflow filter bag 30.In addition, since filter mantle 40 defines the deformed shape of filter bag 30,
But also filter bag 30 will not be destroyed because deformation is too big.
Since the effect of filter mantle 40 is to protect filter bag 30, avoid filter bag 30 that biggish deformation occurs, that is,
Filter mantle 40 needs itself guarantee under biggish pressure will not deformation occurs.Therefore, it is preferable that rigidity can be selected in filter mantle 40
Metal material or high molecular synthetic material.Also, filter mantle 40 is coated on the periphery of filter bag 30, and filtered slurry flows into
In the space that filter mantle 40 surrounds, if filter mantle 40 be it is enclosed, slurry can not by filter mantle 40 from discharge port 11a flow
Out.Therefore, the second mesh 42 is additionally provided on filter mantle 40, filtered slurry can flow out to filter mantle 40 through the second mesh 42
Outside, and discharge port 11a is eventually flowed to.
Specifically, filter mantle 40 is wire mesh enclosure.Wherein, wire uses stainless steel, and applies on the surface of wire
Cover resistant material.Stainless steel has preferable rigidity, is not susceptible to deform, can preferably limit the deformation shape of filter bag
Shape.Chemical substance can be avoided wire and be corroded by coating resistant material containing there are many in slurry.
Also, the optional control in the aperture of the second mesh 42 of filter mantle 40 is in 5.0mm or less.The aperture of second mesh 42 is not
Preferably excessive, otherwise a part of filter bag 30 easily propagates through the second mesh 42, and filter bag 30 connects with wire in filter mantle 40
Touching, friction are then easier to destroy filter bag 30.By the pore size control of the second mesh 42 in 5.0mm hereinafter, then can preferably keep away
The a part for exempting from filter bag 30 passes through the second mesh 42, prevents filter bag 30 from wrecking.
In the present embodiment, filter bag 30 is filter bag made of non-woven fabrics.Woven fabric is will be orthogonal by loom
Warp yarn and weft threads are interwoven according to certain rules, thus are more easily deformed when by active force.And non-woven fabrics does not have
There is filling yarn, only textile staple or long filament are oriented or then random alignment, formation fibre net structure use machine
Tool or chemical method are reinforced.It is more difficult to deform compared to there is woven fabric.It follows that 30 phase of non-woven fabrics filter bag
It deforms to more difficult.Even if will not largely increase the hole of the first mesh under biggish pressure atmosphere
Diameter, to be more effectively filtered to slurry.
Further, using the optional control of the thickness of filter bag 30 made of non-woven fabrics between 2.5mm-3.0mm.Nothing
The thickness of woven fabric is bigger, then relatively more difficult to deform, because of the aperture without largely increasing the first mesh,
Filter bag 30 will not be made excessive because deforming due to is ruptured.But the thickness of non-woven fabrics also should not be too large, the nonwoven of excessive thickness
On the one hand cloth is difficult to form, on the other hand also result in the rising of cost.Specifically, filter bag 30 with a thickness of 2.8mm.
In the present embodiment, using the optional control in the aperture of the first mesh of filter bag 30 made of non-woven fabrics at 40 μm -60
Between μm.The aperture of first mesh depends on pattern-printing and dyeing in the size and cloth of the impurity such as the particulate matter in slurry to be filtered
Quality.Inventor is the study found that when the aperture of the first mesh is greater than 60 μm, especially at 80 μm or more, a large amount of impurity
It can be attached on the cloth of pattern-printing and dyeing, seriously affect the appearance of cloth, reduce the quality of cloth.When the aperture of the first mesh is small
In 40 μm, there is preferable appearance although making the cloth of pattern-printing and dyeing, it can largely reduce slurries filtration device
100 rate of filtration extends filtration time, reduces production efficiency.
