Abstract
A rotation pressurization dehydrator adapted to locally increase the compressive force on moving dehydrated cake so as to efficiently reduce the liquid content of its region for which dehydration has not been sufficient by a conventional rotation pressurization dehydrator, whereby in discharged, dehydrated cake, the difference in liquid content among regions is made small. In a rotation pressurization dehydrator (3) which, as a raw material advances in an annular filter chamber (41) formed around a rotary shaft (32), gradually applies a pressure to the material to change the liquid material into cake, thereby dehydrating the material, projections (51) are disposed on the inner peripheral surface (34c) of an outer ring spacer (34) so as to further reduce the liquid content of the dehydrated cake.
Description
Technical field
The present invention relates to the raw material (processing stoste) that contains solid content filter, take off liquid, with the device of solid and fluid separation applications, it is indoor to be particularly related to the annular filter that forms at two circular sieves, inner ring bushing and outer ring lining by rotation, raw material can be filtered, takes off the rotation pressurization dehydrator of liquid.
Background technology
Rotation pressurization dehydrator (ロ one リ one プ レ ス Off イ Le ), for example, shown in TOHKEMY 2001-113109 communique, it is indoor that the raw material importing is formed on the axial annular filter of rotation, by making the sieve rotation of annular, with this raw material is forwards advanced, pressurize, take off liquid gradually and handle.
Figure 12 is the profile of general rotation pressurization dehydrator 101 before.As shown in the figure, raw material imports in the filter chamber 110 from raw material supplying mouth 108, by and the sieve 105 of rotation between the frictional force that produces, in filter chamber 110, advance successively towards predetermined direction (direction of arrow D among Figure 12).
At this moment, owing on sieve 105, form a plurality of apertures, so in the process of advancing in filter chamber 110 along with raw material, the moisture in the raw material passes the aperture of this sieve 105, is discharged to gradually outside the filter chamber 110.Specifically, be the raw material of liquid condition in the time of in the importing machine, through during about 1/3 position (position of P1 among Figure 12) of operation, become semi-solid, become pie (taking off liquid filter cake (taking off liquid ケ one キ)) at last, discharge outside machine from filter cake outlet 109.
In addition, because sieve 105 rotates continuously, so, with raw material or take off the liquid filter cake, through initial stage filtration zone Q1 (near the raw material supplying mouth 108 near the zone the P1), filter constricted zone Q2 (near the P1 near the zone the P2), final expressing zone Q3 (near the P2 to the zone of filter cake outlet 109), return initial stage filtration zone Q1 again, carry towards direct of travel continuously.
Rotation pressurization dehydrator before as mentioned above, in the time of in aqueous raw material importing machine, filters, takes off liquid and handle in machine, with filtered fluid with take off the liquid filter cake and discharge outside the machine respectively.Taking off in the liquid filter cake of discharging, preferably liquid holdup is even.
But, in rotation pressurization dehydrator before, have the difference because of the position, the differentiated problem of liquid holdup of taking off the liquid filter cake.Specifically, filter chamber 110 and filter cake path 112, its section is rectangle (referring near Figure 13 of the section of the filter cake path 112 the expression filter cake outlet 109), pass through travel path, different bigger squeeze forces, result, different positions to taking off the effect of liquid filter cake, it is inequality to take off liquid speed, and liquid holdup just has deviation.
For example, by near the position (in Figure 13, being L3, C3, R3) of outer ring lining 103 take off the liquid filter cake, than by the liquid holdup height that takes off the liquid filter cake near the position (being L1, C1, R1 in Figure 13) of inner ring bushing 104 or guiding piece 106; In addition, by central portion (among Figure 13 for C1～C3) take off the liquid filter cake, than by taking off liquid filter cake liquid holdup height near the position (being L1～L3 among Figure 13, R1～R3 etc.) of sieve 105,105 or filter cake via sidewall 107,107.
That is, taking off in the liquid filter cake outside the machine of being discharged to exists and takes off the inadequate position of liquid, and the result can not form uniform liquid holdup on the whole.
Summary of the invention
" high dehydration type rotation pressurization dehydrator " of the present invention proposes in order to solve above-mentioned the problems of the prior art, rotation pressurization dehydrator of the present invention, advance in the filter chamber that is formed at the axial ring-type of rotation along with making raw material, raw material is little by little exerted pressure, carry out processed by making aqueous raw material become pie, the liquid holdup of liquid filter cake (taking off liquid ケ one キ) is taken off in one of configuration or more than or equal to two thrust on the inner peripheral surface of above-mentioned outer ring lining with further reduction.
In addition, thrust is being set on the width of outer ring lining when being the same height, make the sectional area of filter chamber reduce the size that is equivalent to its height, can strengthen the squeeze force that takes off the effect of liquid filter cake, liquid holdup is reduced by these thrust tops with this.
In addition, the width dimensions of thrust can be set at littler than outer ring lining, and thrust also can be configured in the width central authorities of outer ring lining and/or near the position of the lateral margin of outer ring lining.
And, at this moment, be configured in the height dimension of the thrust of central authorities, preferably be set at bigger than the thrust of the position that is configured in close lateral margin.

The specific embodiment
Below, with reference to the description of drawings embodiments of the present invention.Fig. 1 is the profile of the essential structure of expression high dehydration type rotation pressurization dehydrator 3 of the present invention.Fig. 2 is the AA line profile of rotation pressurization dehydrator 3 shown in Figure 1.As shown in the figure, this rotation pressurization dehydrator 3 is made of rotating shaft 32, inner ring bushing 33, outer ring lining 34, two rings shape sieve 35, scraper plate 40, guiding piece 36, raw material supplying mouth 38, filter cake outlet 39, back pressure plate 50, overcoat casing 37 etc.
In this rotation pressurization dehydrator 3, supply with driving force at illustrated drive unit never, when making rotating shaft 32 rotations, be fixed on the inner ring bushing 33 around the rotating shaft 32 and be fixed on two sieves 35 on the inner ring bushing 33, with rotating shaft 32 rotations.On sieve 35, the many apertures about 0.1～0.5mm have been formed.
In the present embodiment, the speed rotation that sieve 35 turns left right with per minute 0.1～2, under this state, from raw material supplying mouth 38 base feeds the time, raw material is filtered by sieve 35, is separated into solid content and filtrate.The solid content that filters out, the scraper plate 40 that is configured in the initial stage filtration zone is scraped and is got, and is transported in the filter chamber 41 as concentrated filter cake, in this process, further takes off liquid, becomes and take off the liquid filter cake.
Taken off liquid, liquid holdup has reduced takes off the liquid filter cake, increase with the friction of 35 on sieve, opposing be located at the back pressure plate 50 of filter cake outlet 39 resistance, carry towards outlet 39.At this moment, because the translational speed of taking off the liquid filter cake, than make the translational speed little (promptly slack-off) of taking off the sieve 35 that the liquid filter cake moves by skin-friction force, so, filter in the early stage in the operation, entered the interior solid content of aperture of sieve 35, pulled out towards taking off liquid filter cake one side (41 inboards, filter chamber), as a result, filtering surface (medial surface of sieve 35) usually is updated.Therefore, on sieve 35, do not produce obstruction, can filter and take off liquid effectively.
Like this, supply to the solid content in the raw material in the filter chamber 41, along with taking off liquid near filter cake outlet 39, the liquid filter cake that takes off that reaches the regulation liquid holdup at last is discharged from.But, so directly discharging when taking off the liquid filter cake, by near the position of outer ring lining 34 take off the liquid filter cake, than the liquid holdup height that takes off the liquid filter cake by radial direction inboard (position of close inner ring bushing 33 or guide member 36).In addition, by central portion take off the liquid filter cake, than by the liquid holdup height that takes off the liquid filter cake near the position of sieve 35,35 or filter cake path 43 sidewalls.
For this reason, in order to eliminate these " liquid holdup is different because of the position ", in the rotation pressurization dehydrator 3 of present embodiment, on the inner peripheral surface 34c of outer ring lining 34, be provided with three half-terete thrusts 51.These thrusts 51, its width dimensions all with outer ring lining 34 about equally.In addition, on width, has the same height.In addition, the number of the thrust 51 of configuration is not limited to three, can only dispose one, also can dispose about ten.
These thrusts 51 make the sectional area of filter chamber 41 reduce to be equivalent to its size highly, so can strengthen the squeeze force that takes off the effect of liquid filter cake by these thrust 51 tops.Therefore, the liquid holdup that takes off the liquid filter cake of the position of having passed through close outer ring lining 34 is reduced, can eliminate " liquid holdup is different because of the position ".
In addition, take off the liquid filter cake passed through thrust 51 above after, the height of filter chamber 41 and sectional area return to original size, so, at this moment, take off the position of liquid filter cake and replace at above-below direction.Because in filter chamber 41, produce such " replacement at position ", so, can avoid the high position of liquid holdup to be partial to the situation of a part.As a result, can eliminate " liquid holdup is different because of the position ".
In addition, also can be configured in thrust shown in Figure 3 52 on the inner peripheral surface 34c of outer ring lining 34, replace thrust 51 shown in Figure 1.The thrust 52 of Fig. 3 is shapes (semiellipsoid) that ellipsoid is half-and-half cut apart along length axes, and its length direction is consistent with the direct of travel that takes off the liquid filter cake.In addition, as seen from Figure 3, this thrust 52, its width dimensions are set at width dimensions about about 1/3rd of outer ring lining 34, and are configured in the width central authorities of outer ring lining 34.
Like this, when thrust 52 being configured in the width central authorities of outer ring lining 34, can improve the squeeze force that takes off the effect of liquid filter cake, can reduce taking off of discharge liquid holdup in the liquid filter cake, that pass through the position of central portion by filter chamber's 41 central portions (C3 among Figure 13).In addition, this thrust 52, the direct of travel that takes off the liquid filter cake that change is advanced along the central portion of the inner peripheral surface 34c of outer ring lining 34, its direction that reaches towards the top near left and right sides sieve 35 is pushed, like this, can further improve the squeeze force on the liquid filter cake of taking off around acting on, the result can further reduce the liquid holdup that takes off the liquid filter cake of discharge.
In addition, the thrust 52 that replaces Fig. 3 also can obtain same effect by two (or one) hemispheric thrusts 53 as shown in Figure 4 being configured in the central authorities of the inner peripheral surface 34c of outer ring lining 34.
In addition, also can be as shown in Figure 5, be width dimensions about about 1/3rd hemispherical thrust 53 of outer ring lining 34, respectively dispose one in position near both side edges 34d, the 34e of outer ring lining 34.In addition, two thrusts 53 preferably are not the widths that is configured in outer ring lining 34 side by side, but one at another oblique rear, promptly with staggering the configuration.
Under situation about constituting like this, reduce to be equivalent to the size of thrust 53 by the sectional area that makes filter chamber 41, can strengthen the squeeze force that takes off the effect of liquid filter cake to the periphery by these thrusts 53, the liquid holdup reduction of taking off the liquid filter cake can be made, the problem of " liquid holdup is different because of the position " can be eliminated by the position of close outer ring lining 34.
In addition, not only replace at above-below direction at the position of taking off the liquid filter cake of advancing in filter chamber 41, and replace in the horizontal direction, like this, can avoid the high position deflection part of liquid holdup, help to eliminate the problem of " liquid holdup is different because of the position ".
Specifically, usually, in the space of filter chamber 41, by central authorities take off the liquid filter cake, than by the liquid holdup height that takes off the liquid filter cake near the position (the both side edges 34d of close outer ring lining 34, the position of 34e) of sieve 35.But in the present embodiment, take off liquid filter cake (liquid holdup lower take off liquid filter cake) what advance near the position of side's lateral margin 34d, thrust 53 by upstream side pushes to central authorities, simultaneously, originally take off liquid filter cake (liquid holdup is than the higher liquid filter cake that takes off), released towards position, in addition near the lateral margin 34e of opposition side what central authorities advanced, by the thrust 53 of downstream side, carry out same " replacement " in the opposite direction.
When producing such " replacement of horizontal direction ", originally passed through to be not easy to take off the position that liquid level is put, move towards the easier position of taking off liquid, like this, can eliminate the problem of " liquid holdup is different because of the position ".
In addition, also can be between Fig. 5, thrust 53,53 shown in Figure 6, the configuration height size is than they big thrust 54 (see figure 7)s.At this moment, except above-mentioned effect, can also improve the squeeze force at the highest position (outer ring lining 34 sides and central portion) of liquid holdup in the concentrated area, can reduce the liquid holdup of these parts effectively.
In addition, as Fig. 8～shown in Figure 11, under the situation of the overhang that can change thrust 55～59, can control the liquid holdup in the liquid filter cake of taking off of discharge.
Specifically, in the structure example of Fig. 8, on outer ring lining 34, form through hole, the downside of thrust 55 from this through hole inserted, make the top of thrust 55 outstanding upward from the inner peripheral surface 34c of outer ring lining 34, with the lower side of bolt 65 insertion thrusts 55, thrust 55 can be fixed like this.Except illustrated thrust 55, also prepare the height dimension thrust different (for example, the thrust 56 that dots among this figure etc.) in advance, according to the proterties of taking off the liquid filter cake with it, change the thrust that highly is more suitable for, can change the overhang of thrust with this.
In the structure example of Fig. 9, at thrust 57 and between following its bolt of side bearing 65, dispose spring 66, thrust 57 is in the state that is pushed upward by the elastic force of this spring 66.When the liquid holdup of the filter cake of advancing in filter chamber 41 hangs down, because the pressure of filter cake increases, so the spring 66 of support projection thing 57 is yielded to the pressure of the filter cake of advancing and is compressed, thrust 57 be depressed (become from state shown in Fig. 9 (1) and be the state shown in Fig. 9 (2)).At this moment, because the overhang of thrust 57 reduces, so, acting on the squeeze force that takes off on the liquid filter cake that passes through and also reduce, the liquid holdup of filter cake increases as a result.
On the other hand, when the liquid holdup of the filter cake of advancing in filter chamber 41 was high, because the pressure of filter cake reduces, so the spring 66 of support projection thing 57 stretches, thrust 57 was pushed upwardly (become from state shown in Fig. 9 (2) and be the state shown in Fig. 9 (1)).At this moment, because the increase of the overhang of thrust 57, so, act on the squeeze force that takes off on the liquid filter cake that passes through and also increase, the result, the liquid holdup of filter cake reduces.
Like this, in the structure example of Fig. 9, make the overhang of thrust 57 carry out following variation, that is, when the liquid holdup of the filter cake of advancing is higher than benchmark, make its attenuating in filter chamber 41; When the liquid holdup of the filter cake of advancing in filter chamber 41 is lower than benchmark, it is uprised.As a result, can control the liquid holdup of filter cake.
In the structure example of Figure 10, thrust 58 is suppressed upward with the pressure of fluid (air, water or wet goods).Specifically, make fluid flow in the enclosure space (cylinder pressure 67) of thrusts 58 belows or and discharge, to the pressure of thrust 58 reactive fluids, with its jack-up upward from this space by managing 68.Like this, with the structure example of Fig. 9 similarly, the overhang of thrust 58 is changed, that is, when the liquid holdup of the filter cake of advancing is higher than benchmark, make its reduction in filter chamber 41; When the liquid holdup of the filter cake of advancing in filter chamber 41 is lower than benchmark, it is uprised.As a result, can control the liquid holdup of filter cake rightly.
In the structure example of Figure 11, section is fan-shaped thrust 59, can be around central shaft 59a rotation (from the scope of Figure 11 (1) to (3)) in the scopes of about 90 degree, with the dipper crowding gear of motor or helical spring etc., with thrust 59 upward (in Figure 11, towards counter clockwise direction) suppress.Like this, with the structure example of Fig. 9, Figure 10 similarly, the overhang of thrust 59 is changed, that is, when the liquid holdup of the filter cake of advancing is higher than benchmark, make its reduction in filter chamber 41; When the liquid holdup of the filter cake of advancing in filter chamber 41 is lower than benchmark, it is uprised.As a result, can control the liquid holdup of filter cake rightly.In addition, the arrow D among Figure 11, the direct of travel of the filter cake in the expression filter chamber 41.
Fig. 1 is to thrust 51～59 shown in Figure 11, though also can be located at the full week of outer ring lining 34, normally from preceding half to filter cake path 43 of the filter chamber 41 of taking off liquid later half, disposes one to several (for example about ten).In addition, when disposing several, their interval also can be unequal.The height of thrust 51～59 (from the outstanding overhang of the inner peripheral surface 34c of outer ring lining 34) is preferably below 20% or 20% of height dimension (deducting the size of the outside dimension of inner ring bushing 33 from the internal diameter size of outer ring lining 34) of filter chamber 41 or filter cake path 43.If greater than this value, then the transporting resistances that take off the liquid filter cake in filter chamber 41 or the filter cake path 43 will become excessive, and treating capacity (treatment effeciency) will reduce, and perhaps produce the problem of machine internal congestion etc.And if below 20% or 20%, the possibility that then produces these problems is less, can reach its intended purposes preferably.
In addition, the variable range of the overhang of thrust 55～59 preferably also is below 20% or 20% of height dimension of filter chamber 41 or filter cake path 43.
In addition, the shape of thrust 51～59 can not be a curved surface also, for example can be the shape of triangular pyramid, rectangular pyramid, circular cone etc.
