Among Fig. 1,, be provided with along the separating plate group 20 of the rotating shaft direction lamination polylith lampshade shape separating plate 2 of rotary body 1 in the inside of rotary body 1.The separating plate 2 that constitutes this separating plate group 20 is extremely shown in Figure 6 as Fig. 2, is by the processing of extending flat board to be processed into conical butt.
In each layer of separating plate group 20, relatively the lamination direction up and down each separating plate 2 of upside and the gap up and down between the following separating plate 2, promptly at Fig. 2 to the separating plate 2 shown in Figure 6, the inside of the taper seat 21 of the upside separating plate 2 in each layer (below) 212 and the outside of the taper seat 21 of downside separating plate 2 (above) between 211, form taper seat gap (not shown), as the gap that imports (the importing direction of representing processed liquid at a plurality of arrows shown in the separating plate group 20 of Fig. 1) processed liquid towards oblique upper.
The outside of the taper seat 21 of the separating plate 2 below being positioned at relatively (above) on 211, roughly element of cone direction along this taper seat 21, for example be divided into 8 parts of modes that form 8 separated spaces 4 in accordance with regulations at interval in the direction of rotation of rotary body 1 (right of figure=counterclockwise) in the present embodiment, in plane, a plurality of separated spaces are set cut apart projecting strip part 3 with radial from the pivot side.
This seperator, carries out centrifugation in the following manner and handles roughly by first separation and secondary separation the separating treatment of processed liquid (fuel oil or the lubricating oil that contain mud or moisture content).
At first, in Fig. 1, processed liquid injects in the rotary bodies 1 from the introducing port 11 of the rotating shaft upper edge direction of rotation setting of rotary body 1, and the centrifugal force that produces of the rotation of the high speed by rotary body 1 is separated into bigger heavy-fluid of the less light liquid of proportion, proportion and solid etc. (below, be referred to as first separation and handle) with processed liquid.
Handle the less light liquid of the proportion that separates by this first separation and vertically run through this separating plate group 20 to upside from the downside of separating plate group 20, at least in each separated space 4, upwards flow through each opening 22 that is set up in the mode that runs through this separated space 4, flow into each separated space 4 of each layer from the bottom to top successively, and diffusion in each separated space 4.
Below, after-treatment is described.
The processed liquid of diffusion in each separated space 4, because of being subjected to centrifugal action, be diffused into each separated space 4 from the opening 22 of this separated space 4, and, the liquid of processed liquid is between the taper seat 21 of separating plate 2,2 up and down, promptly going up in the separated space 4 in gap between outside (top) 211 of taper seat 21 of the inside (following) 212 of taper seat 21 of separating plate 2 and following separating plate 2, is the rotating shaft direction towards separating plate 2 centers, climbs mobile along the inclined plane 211 of taper seat 21 down.Should flow and promptly upwards flow, in separating plate group 20 shown in Figure 1, direction and towards shown in the axial a plurality of arrows of rotation obliquely.
Like this, through the gap of the separated space 4 of each layer separating plate 2 of separating plate group 20, the lighter processed liquid in that the upside of separating plate group 20 promptly makes progress finally reclaims as scavenging solution near the recovery mouth 15 that is provided with the rotating shaft of rotary body shown in Figure 11.
On the other hand, sneak into the centrifugal sedimentation that the high speed rotation by rotary body 1 of proportion is bigger in the various solid impurities of processed object in the processed liquid particle forms, be collected to the maximum gauge portion 13 in the space 12 in the rotary body 1 fast, and be in due course in a suitable manner, the outlet 14 of the maximum gauge portion 13 around the main body that is arranged on rotary body 1 is discharged outside the rotary bodies 4.This maximum gauge portion 13 is observed from the inside of rotary body 4, is the most peripheral spatial portion of inside, and is control of dust, the gathering place of interim storage solid impurity.
In addition, the processed liquid that proportion is bigger or in processed liquid contained solid impurity particle etc., in each separated space 4 that constitutes roomy sedimentation face (circular cone area * separating plate 2 quantity of separating plate 2) that forms by separating plate group 20, the sedimentation face that falls to separated space 4 promptly forms the inside (following) 212 sides (the top board side that falls to this separated space 4 of centrifugal force) of the taper seat 21 of the last separating plate 2 of (top board side) above being positioned at relatively of separated space 4, and along the taper seat 21 of sedimentation to i.e. base 41 side flow of this taper seat 21 of the neighboring of this separated space 4 41 sides.Below, claim this discharge that is called from separated space 4 of flowing to flow.
Like this, the solid impurity particle of the various different qualities of sedimentation is discharged when flowing to the neighboring 41 of each separated space 4 in each separated space 4, along direction of rotation to form (separation) a plurality of these separated spaces 4.Fore-and-aft direction in direction of rotation is provided with 2 a pair of prominent bars 3 of separated spaces separation of relative formation at interval, (for example separate projecting strip part 3 by the separated space that is positioned at the direction of rotation rear in 3, separate the corresponding separated space of projecting strip part with the separated space shown in the symbol 3F among Fig. 4 and separate projecting strip part 3R), say exactly, it is the rotary face edge 31 at the edge (leading edge) of the direction of rotation side by separating projecting strip part 3R at this separated space, shown in the flow trace of dotted arrow among Fig. 4 or Fig. 5, in the time of the direct solid foreign particle, separate projecting strip part 3R by separated space it is scanned out from this separated space 4, and base 41 (neighboring 41 of this separating plate 2) side of 212 sides is carried in the last separating plate 2 of these separated space 4 neighborings 41 sides.
Afterwards, in Fig. 1, as mentioned above, be delivered to its neighboring 41 sides from each separated space 4, and discharge separating plate group 20 outer solid impurities (not shown) arrive the space 12 in separating plate group 20 rotary body 1 on every side, final with above-mentioned the same, maximum gauge portion 13 in the rotary body 4 that is called as solid impurity control of dust place of interim storage most peripheral spatial portion in this rotary body 4, and by suitable mode outside outlet 14 discharge rotary bodies 4.
As mentioned above, form separated space and separate projecting strip part 3, more precisely forming separated space, to separate the mode of rotary face edge 31 of projecting strip part 3 as follows.To be full of the solid impurity particle that swims in the processed liquid of separated space 4 guides to separated space and separates in the rotary face edge 31 of projecting strip part 3 under centrifugal action, in this separated space 4, outside from this separated space 4, promptly to the outside of separating plate group 20, when discharge is mobile in this separated space 4, in this rotary face edge 31, there are the various solid impurity particles of the difference of weight to increase because of the quality that the difference of mutual translational speed or the staggered contact that causes of stream or collision (dotted arrow of Fig. 5) make unit cell.
The distribution of separating projecting strip part 3 with respect to the separated space of the element of cone of separating plate 2 taper seats 21, be that taper seat 21 is integrated with assigned position welding formation relatively for separated space separation projecting strip part sheet (3), for example in the present embodiment, though with the element of cone of taper seat 21 are mode tilt distribution to intersect.But be not limited to this, for example,, parallelly with element of cone can arrange (distributions) separated space separation projecting strip part 30 (, will be described further subsequently) in the direction of element of cone about Fig. 7 as separating plate 20 as shown in Figure 7.
No matter which kind of is, separated space separation projecting strip part 3 equal one are welded in and are set on the assigned position of taper seat 21 outer surface many places (being 8 places among the embodiment), be that separated space after integrated is separated projecting strip part 3, as the device that scans out base 41 sides (below, this effect is called the effect of scanning out) of these separated space 4 belows by centrifugal force, with the solid impurity particle in this separated space 4 relatively.
The gradient of the separated space separation projecting strip part 3 the in the present embodiment i.e. mode of being obliquely installed is: with respect to the element of cone of separating projecting strip part 3 by this separated space, the upper end side that separated space is separated projecting strip part 3 is positioned at the direction of rotation side, the bottom side that separated space is separated projecting strip part 3 is positioned at rear swivel side (below, abbreviate inclination as).
In addition, the shape that separated space is separated the rotary face edge 31 of projecting strip part 3 can be bent to form to describe mode, in the length range of rotary face edge 31, the curve that bloats along the opposite direction of the direction of rotation of rotary body 4 (being right rotation among the figure) (among the figure for left to).For example, the leading edge that separated space can be separated projecting strip part (sheet) 3, be to be bent into curve (not shown) in rotary face edge 31 length range, perhaps, as shown in the figure, also can will form near near the mode of the part 41 sides of taper seat 21 bases in rotary face edge 31 total lengths with degree of depth bending.
This generation type then can realize being in contact with one another or colliding the quality increaseization that forms by the solid impurity particle in wide region, scans out effect thereby can bring into play it effectively.But, be not that certain so simply, rotary face edge 31 total lengths can be linear yet, promptly separated space is separated 3 of projecting strip parts (sheet) as rectilinear band.
In addition, because " ∧ " font separated space shown in the embodiment is separated the shape of projecting strip part (sheet) 3, in fuel oil or the Separation of Solid and Liquid performance test of lubricated wet goods, be the optimum shape of finding in the experiment through experimental results show that repeatedly as processed liquid with marine diesel engine.Therefore, according to the composition of the performance of seperator, purposes, processed liquid or sneak into the physical property etc. of the solid impurity (particle) in the processed liquid, separated space is separated the shape of projecting strip part 3 can be different.
For example, it is linear that the separated space of separating plate 20 shown in Figure 7 is separated projecting strip part (sheet) 3, and it is parallel with element of cone that this separated space is separated projecting strip part (sheet) 3, promptly arranges (distribution) along the direction of element of cone.In addition, this rectilinear separated space is separated projecting strip part (sheet) the 3rd, can not obtain the action effect of bend such as " ∧ " font.
The separating plate 3 of present embodiment forms as follows.Based on the manufactured Frusto-conical taper seat body 2 of following mode, in this main body is that the outer surface of taper seat body 2 is that taper seat 21 (211) is gone up on predetermined a plurality of desired locations, in the locating hole of location with the circular cone face mould that will insert respectively as following localization method with a plurality of banded separated space separation projecting strip part sheet 3 of these taper seat body 2 each self-formings, perhaps, when inserting, be integral by the welding manner and the above-mentioned taper seat bodily form, thereby be wholely set on the outer peripheral face of this taper seat body.
Below, will separate the manufacturing of the separating plate 2 of projecting strip part 3 and describe possessing this separated space.
When making separating plate,, must prepare separated space separation projecting strip part sheet 3 that (productions) form respectively as the taper seat body 2 of separating plate main body, with separating plate in advance and as the location of localization method circular cone face mould as prerequisite.
The manufacturing of taper seat body
At first, prepare square plate, this square plate is processed into cone shape (below, this operation is called the manufacturing procedure of extending) by the processing machine of extending with this square plate as raw material.Square plate is the size according to the target separating plate, and plate material (scale plate 2000 * 1000 2B JIS specifications) is cut into required square (below, this operation is called the square cut operation).
