In Fig. 1, in the inside of rotary body 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.The separating plate 2 that consists of this separating plate group 20 is as extremely shown in Figure 6 in 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 in each separating plate 2 of upside of lamination direction up and down and the gap up and down between lower separating plate 2, namely 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 that represents processed liquid at a plurality of arrows towards oblique upper shown in the separating plate group 20 of Fig. 1) processed liquid.
The outside of the taper seat 21 of the separating plate 2 below relatively being positioned at (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 the interval in accordance with regulations in the direction of rotation of rotary body 1 (right of figure=counterclockwise) in the present embodiment, a plurality of separated spaces are set cut apart projecting strip part 3 with radial from the pivot side in plane.
This seperator roughly by first separation and secondary separation, carries out centrifuging treatment to the separating treatment of processed liquid (fuel oil or the lubricating oil that contain mud or moisture content) in the following manner.
At first, in Fig. 1, processed liquid injects in rotary bodies 1 along the introducing port 11 that direction of rotation arranges from the rotating shaft of rotary body 1, and the centrifugal force that produces of the High Rotation Speed by rotary body 1 is separated into the larger heavy-fluid of the less light liquid of proportion, proportion and solid etc. (below, be referred to as first separation and process) with processed liquid.
Process the less light liquid of the proportion that separates by this first separation and vertically run through this separating plate group 20 from the downside of separating plate group 20 to upside, at least upwards flow through in the mode that runs through this separated space 4 each opening 22 that is set up in each separated space 4, flow into successively each separated space 4 of each layer from the bottom to top, and diffusion in each separated space 4.
Below, after-treatment is described.
Processed liquid in each separated space 4 interior diffusions, because being subject 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 up and down separating plate 2,2 taper seat 21, namely go up in the separated space 4 of the inside (following) 212 and outside (top) 211 gaps of the taper seat 21 of lower separating plate 2 of taper seat 21 of separating plate 2, be the rotating shaft direction towards separating plate 2 centers, climb mobile along the inclined plane 211 of lower taper seat 21.Should flow and namely 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 the upside of separating plate group 20 namely makes progress finally reclaims as scavenging solution near the recovery mouth 15 that arranges the rotating shaft of rotary body shown in Figure 11.
On the other hand, sneak into the centrifugal sedimentation that particle that in the various solid impurities of processed object in processed liquid, proportion the is larger High Rotation Speed by rotary body 1 forms, the maximum gauge section 13 in the space 12 of quick collecting to the rotary body 1, and be in due course in a suitable manner, the outlet 14 of the maximum gauge section 13 around the main body that is arranged on rotary body 1 is discharged outside rotary bodies 4.This maximum gauge section 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 larger or in processed liquid contained solid impurity particle etc., in each separated space 4 that consists of roomy sedimentation face (circular cone area * separating plate 2 quantity of separating plate 2) that is formed by separating plate group 20, the sedimentation face that falls to separated space 4 namely 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 upper separating plate 2 of (top board side) above relatively being positioned at of separated space 4, and i.e. base 41 side flow of this taper seat 21 of neighboring 41 sides along the taper seat 21 of sedimentation to this separated space 4.Below, claim this discharge that is called from separated space 4 of flowing to flow.
Like this, discharge to the neighboring 41 of each separated space 4 when flowing at the solid impurity particle of the various different qualities of each separated space 4 interior sedimentations, along direction of rotation to form (separation) a plurality of these separated spaces 4.2 a pair of separated spaces of relative formation are set at the fore-and-aft direction interval of direction of rotation separate ridges 3, (for example separate projecting strip part 3 by the separated space that is positioned at the direction of rotation rear in 3, separate separated space corresponding to projecting strip part with the separated space shown in symbol 3F in 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, as shown in the flow trace of dotted arrow in Fig. 4 or Fig. 5, in the time of guiding solid impurity particle, separating projecting strip part 3R by separated space scans out it from this separated space 4, and base 41 (neighboring 41 of this separating plate 2) side of 212 sides is carried in the upper separating plate 2 of these separated space 4 neighboring 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, interim storage is in the interior maximum gauge of rotary body 4 section that is called as solid impurity control of dust place 13 of the interior most peripheral spatial portion of this rotary body 4, and by appropriate ways 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.When will be full of the solid impurity particle that swims in the processed liquid of separated space 4 and guide to separated space separate the rotary face edge 31 of projecting strip part 3 under centrifugal action, in this separated space 4, outside from this separated space 4, namely to the outside of separating plate group 20, when moving from the interior discharge of 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, although with the element of cone of taper seat 21 are the mode tilt distribution of intersecting.But be not limited to this, for example, as separating plate 20 as shown in Figure 7, parallelly with element of cone can arrange (distributions) separated space separation projecting strip part 30 (about Fig. 7, will be described further subsequently) in the direction of element of cone.
No matter which kind of is, the equal one of separated space separation projecting strip part 3 is welded in and is set on taper seat 21 outer surface many places (being 8 places in embodiment) assigned positions, be that separated space after integrated is separated projecting strip part 3, as by centrifugal force, the solid impurity particle in this separated space 4 is scanned out relatively the device of base 41 sides (below, this effect is called the effect of scanning out) of this separated space 4 belows.
The gradient of the separated space separation projecting strip part 3 in the present embodiment namely is obliquely installed mode and is: with respect to separate the element of cone of 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, referred to as tilting).
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 in figure) (in 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 taper seat 21 base 41 sides with degree of depth bending in rotary face edge 31 total lengths.
This generation type can realize being in contact with one another or colliding by the solid impurity particle quality increaseization that forms in wide region, scans out effect thereby can effectively bring into play it.But, be not that certain so simply, rotary face edge 31 total lengths can be linear yet, namely separated space is separated 3 of projecting strip parts (sheet) as rectilinear band.
In addition, the shape of separating projecting strip part (sheet) 3 due to " ∧ " font separated space shown in embodiment is, in fuel oil or the Separation of Solid and Liquid performance test of lubricated wet goods as processed liquid with marine diesel engine, be the optimum shape of finding in experiment through repeatedly experimental results show that.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 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, namely 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 the bend such as " ∧ " font.
The separating plate 3 of the present embodiment forms as follows.Take the manufactured Frusto-conical taper seat body 2 of following mode as main body, be on the upper predetermined a plurality of desired locations of taper seat 21 (211) at the outer surface that this main body is taper seat body 2, 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 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, the manufacturing that will separate to possessing this separated space the separating plate 2 of projecting strip part 3 describes.
When making separating plate, as prerequisite, 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.
The manufacturing of taper seat body
At first, prepare square plate as raw material, 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.Square plate is the size according to the target separating plate, and plate material (sizing plate 2000 * 1000 2B JIS specifications) is cut into required square (below, this operation is called the square cut operation).
