The specific embodiment
Be that example describes with grading plant of the present invention and with the situation that this grading plant is applied to the shot-peening processing unit (plant) of wet type.In addition, grading plant of the present invention is not limited to the mode that embodiment is put down in writing, and can suitably change as required.And, for the left and right sides above-below direction of present embodiment record, as long as specially do not explain the direction among the figure that just refers to.
(grading plant)
At first, grading plant is described.Grading plant 10 comprises framework 11 and slip introducing mechanism 17.Shown in Fig. 1 (A), framework 1 is tetragonal tubular for cross section, and top (topmost among this figure) stopped up by top board.In the bottom, offer slip introducing port 12a, major diameter particle outlet 13a, minor diameter particle outlet 14a successively according to the order from the left side of this figure.
At major diameter particle outlet 13a and minor diameter particle outlet 14a in the middle of the two, erect in the bottom of framework 11 and to be provided with classification parts 16, these classification parts 16 framework 11 volume inside are separated into slip stream upstream side first reclaim chamber 13 and slip stream the downstream second reclaim chamber 14.These classification parts 16 are tabular, and dispose to form gapped mode between the top of upper end and framework 11.
Near slip introducing port 12a, dispose slip from the bottom of framework towards the top and import parts 15.Slip imports parts 15 and is tabular, and the height and position of upper end (at the above-below direction of Fig. 1 (A)) is lower than the height and position of above-mentioned classification parts 16 upper ends.And slip imports parts 15 and disposes in the mode of surrounding the slip introducing port, reclaims chamber 13 volume inside first and is separated out slip importing chamber 12.In the present embodiment, shown in Fig. 1 (B), utilize the slip be configured in three directions (top among this figure, below, right-hand) to import parts 15 and the left that is positioned at this figure to the sidewall of framework 11 form the space that is the slip that comprise slip introducing port 12a and import chamber 12.In addition, as long as can form this space, direction, shape that the configuration slip imports parts 15 there is no particular determination.For example, also can make three directions (top of this figure, below, left) be first and reclaim the wall of chamber 13, only make a remaining wall (this figure's is right-hand) import parts 15 (with reference to (A) of Fig. 2) for slip, and, also can import parts 15 by the slip that is configured in four direction (top, below, left, right-hand) and constitute (with reference to (B) of Fig. 2).And, the cross section (cross section of the paper vertical direction in Fig. 1 (A)) that slip imports chamber 12 is not limited to the such quadrangle of embodiment, for example also can be the semi-circular shape (with reference to (C) of Fig. 2) that the sidewall that utilizes the slip of drum to import parts 15 and framework 11 forms, also can be only to import the toroidal (with reference to (D) of Fig. 2) that parts 15 form by the slip of drum.
As mentioned above, framework 11 volume inside import parts 15 and 16 separations of classification parts by slip.Thus, beginning to be formed with successively the space that comprises slip introducing port 12a that is slip from the left side imports chamber 12, comprises the space that is second of space that is first that slip imports chamber 12 and major diameter particle outlet 13a reclaiming chamber 13 and comprising minor diameter particle outlet 14a and reclaim chamber 14.
Preferably link valve that is major diameter particle dump valve and the minor diameter particle dump valve (not shown) that the guiding mechanism that possesses obstruction and flow is arranged respectively at above-mentioned major diameter particle outlet 13a and minor diameter particle outlet 14a.Before classification began, major diameter particle dump valve and minor diameter particle dump valve all were closed.
In above-mentioned slip introducing port 12a binding slip introducing mechanism 17 is arranged.Slip introducing mechanism 17 comprises hoisting mechanism (shielding electrodynamic pump) and pipe H1.Utilize pipe H1 to link above-mentioned hoisting mechanism 17 and slip introducing port 12a.And, in above-mentioned hoisting mechanism P1 binding pipe H2 is arranged, utilize pipe H2 to link above-mentioned hoisting mechanism 17 and slurry vessel 22.
And, will in liquid, be dispersed with the slip that the solids of desiring to carry out classification form and drop into slurry vessel 12.Preferably dispose rabbling mechanism (not shown) at slurry vessel, in order to avoid the solids among the slip S are piled up in the bottom.For rabbling mechanism, can utilize stirring vane to stir slip, can utilize current to stir slip, can utilize pump etc. to make slurry circulation and stir, can be any one, and, also can suitably select other known method.
Secondly, by making hoisting mechanism P1 work, slip S is imported in the framework 11 from above-mentioned slip introducing port 12a.The flow velocity of slip S have elect as solids can be in slip import chamber 12 sedimentation and the 0.5～5m/s that can not impact classification.
For the slip S that is imported into from slip introducing port 12a, solids condense each other and form agglomerate (offspring) sometimes.Grading plant of the present invention is to utilize the difference of the sinking speed of solids to carry out classification.If the minor diameter particle forms agglomerate each other, and this agglomerate has under the situation of the equal above sinking speed of major diameter particle, and then this agglomerate is recovered with the major diameter particle, so the effectiveness of classification variation.Therefore, preferably the agglomerate of minor diameter particle is carried out fragmentation and makes it become single particle (primary particle).Import chamber 12 by as present embodiment, forming slip, can carry out fragmentation to the offspring of minor diameter particle.And then, flowing into first in the upper end that slip S imports chamber 12 by slip when reclaiming the chamber, the minor diameter particle becomes primary particle.
In order to carry out fragmentation more reliably, preferred so that the mode that the sectional area of the cross section (cross section of the paper vertical direction in Fig. 1 (A)) of slip importing chamber 12 enlarges along with the last direction in trend Fig. 1 (A) disposes slip importing parts 15.Inflow at slip S is positioned under the situation of above-mentioned scope, and the ratio (S1/S2) of the sectional area S2 of the sectional area S1 of the position of the area maximum of preferred above-mentioned cross section and minimum position is 2.5～5.0, and more preferably 3.0～4.0.For example, can make the slip on the right side among (B) of Fig. 1 import parts 15 and (be preferably 2～4 °) from plumbness towards 2～8 ° of right-hand inclinations, import parts 15 by the slip that makes the above-below direction side and erect setting in the mode that does not tilt, can enlarge the sectional area of cross section.When above-mentioned inclination is lower than 2 °, broken offspring fully.When above-mentioned inclination surpassed 8 °, the stream of slip was imported parts 15 from slip and is peeled off, so the rheology of slip gets unstable.In the present embodiment, above-mentioned inclination is set at 4 °.Thus, the effectiveness of classification κ (D75/D25) of the major diameter particle that is recovered in the first recovery chamber is 1.20～1.75.In addition, effectiveness of classification κ (D75/D25) refers to the ratio with respect to the next 1/4 value of upper 1/4 value (particle diameter is greater than the particle of this particle diameter 25% particle diameter for accumulative total particle diameter frequency curve) (same as described above, as to be 75% particle diameter).
In addition, so-called " sectional area enlarges along with the trend top " not only can be condition of enlarged continuously along with the trend top, also can be a part has same cross-sectional continuously along with the trend top shape.For example, can form begin along with trend from the bottom above and sectional area is enlarged, have the shape of same cross-sectional then along with the trend top continuously.
And, in order to improve effectiveness of classification or the higher limit of classification point to be risen, preferably near the upper end of slip importing chamber 12, dispose acceleration mechanism.Acceleration mechanism preferably can be accelerated the speed of slip S in the stream of not upsetting slip S.In the present embodiment, as shown in Figure 3, the mode that the acceleration components 19 that the longitudinal section is triangular in shape enlarges along with the trend top with the sectional area of its cross section is configured in slip and imports near the upper end of chamber 12.In addition, make the upper end of slip importing parts 15 neighbouring vertical.At the sloping portion 15a that imports parts 15 by slip and above along with trend and after enlarging the sectional area of cross section, acceleration mechanism by the vertical component 15b that is imported parts 15 by acceleration components 19 and slip constitutes makes the sectional area of cross section dwindle gradually along with the trend upper end.By acceleration mechanism, the flow velocity of the slip S when importing 12 upper ends, chamber by slip accelerates, so the rectilinear propagation of minor diameter particle improves.Therefore, the minor diameter particle is easy to move to second and reclaims the chamber.Do not reclaim the chamber and be stranded in first for a long time when reclaiming the chamber when the minor diameter particle moves to second, have the minor diameter particle coacervation and form offspring and reclaim the misgivings of chamber sedimentation first.By accelerating the flow velocity of slip S, can prevent the cohesion of minor diameter particle, can improve effectiveness of classification κ.For acceleration mechanism, can accelerate the flow velocity of slip S by the parts that dispose other shapes, also can be by constituting the flow velocity that sidewall that slip imports chamber 12 is accelerated slip S so that slip imports mode that the sectional area of chamber 12 narrows down near the upper end.
And, when the flow velocity of slip S is fast, make the major diameter particle of sinking speed piece move to the second recovery chamber easily.As mentioned above, accelerate the flow velocity of slip S by utilizing acceleration mechanism, can improve the higher limit of classification point.
In addition, so-called classification point refers to: the distribution of the minor diameter particle after classification and the size distribution of major diameter particle (with respect to the pen amount (Pen amount of particle diameter)), and the particle diameter identical in quality of major diameter particle and minor diameter particle.
Preferably utilizing above-mentioned acceleration mechanism to make slip is 1.0～5.0m/s by the speed that slip imports the upper end of chamber 12.When this speed is lower than 1.0m/s, can't obtain the effect of acceleration mechanism.When this speed surpasses 5.0m/s, can upset the stream of the slip in first recovery, effectiveness of classification reduces.And, reclaiming the rate of climb that slurry level in the chamber is wished the slip located owing to can improve first, therefore can obtain fully be used to making the minor diameter particle reclaim the propulsive force that move the chamber towards second.As a result, the higher limit of classification point is risen.By from above-mentioned scope, selecting the speed of slip, can adjust the classification point, and can carry out high-precision classification.
And the height h3 of deceleration component 19 is preferably 0.2～1.0 with respect to the ratio (h3/h1) that slip imports the height h1 of chamber 12.When being lower than 0.2, therefore the acceleration distance deficiency of slip can't make slip S accelerate fully.Therefore, the higher limit of classification point diminishes, and the adjusting range of classification point narrows down.When surpassing 1.0, it is big that the wall resistance that the boundary between acceleration mechanism and slip S produces becomes, so the acceleration of particle is hindered.
A little less than the adhesion of offspring, under can be the easily broken situation, the sectional area that also can make slip import chamber 12 enlarges gradually along with the trend top.Even if in this case, also can import the above-mentioned acceleration mechanism of chamber 12 configurations at slip as required.
Flow into first by the slip S behind the slip importing chamber 12 and reclaim chamber 13.When the first recovery chamber was full of slip S, the fast major diameter particle of sinking speed sank down into the bottom of the first recovery chamber.On the other hand, the slow minor diameter particle of sinking speed is trapped near the liquid level of slip S.
When first amount that reclaims the slip S of chamber constantly increases and liquid level when crossing the upper end of above-mentioned classification parts 16, the gap inflow second recovery chamber 14 that slip S forms by the top by the upper end of these classification parts 16 and framework 11.Thus, reclaiming near the liquid level that is trapped in slip S in the chamber 13 minor diameter particle first reclaims chamber 14 towards second and moves.
Then, open above-mentioned major diameter particle dump valve and above-mentioned minor diameter particle dump valve, the slip that utilizes grading plant to reclaim respectively to be dispersed with the major diameter particle and be dispersed with the slip of minor diameter particle.At this moment, so that carry out the adjustment of flow from discharge rate (flow of the slip) suitable manner that becomes of major diameter particle outlet 13a and minor diameter particle outlet 14a.For example, when too much from the discharge rate of major diameter particle outlet 13a, slip S does not reclaim the chamber towards second and moves.On the contrary, served as after a little while, many towards the mobile quantitative change of the second recovery chamber, the result, particle diameter moves greater than reclaiming the chamber at second particle that reclaims the target grain size that reclaims the chamber towards second.
The sectional area of cross section dwindles respectively along with tending to major diameter particle outlet 13a and minor diameter particle outlet 14a near the bottom of the first recovery chamber 13 and the second recovery chamber 14.Therefore, major diameter particle and minor diameter particle can not be deposited in first and reclaim the bottom that chamber 14 is reclaimed in chamber 13 and second, but are discharged from framework 11 efficiently.
When first area that reclaims the cross section of chamber 13 is crossed when wide, the minor diameter particle is implemented 13 sedimentations in first back before reclaiming chamber 14 arriving second, when narrow, the major diameter particle before sedimentation with above-mentioned classification parts 16 collisions.Therefore, the preferred above-mentioned slip first sectional area S3 that reclaims the cross section of chamber that imports the place, the top of chamber 12 ratio (S3/S2) of sectional area S2 that imports the cross section of chamber 12 with respect to above-mentioned slip is selected from 2～10.
Grading plant of the present invention can easily change the classification point by changing the interval between above-mentioned classification parts 16 and the above-mentioned top board.In the present embodiment, by classification parts 16 being formed the structure that can load and unload and height (above-below direction in Fig. 1 (A)) the different classification parts 16 that change the outfit, can easily make classification o'clock in the scope change of 100～1000 μ m.When the top of slip importing chamber 12 was too small with the difference of the height and position of the top of classification parts 16, the major diameter particle also was admitted to second and reclaims chamber 14, and when above-mentioned difference was excessive, the height of framework 11 became too high.Therefore, the height h2 of preferred above-mentioned classification parts 16 is 1.2～5.0 with respect to the ratio (h2/h1) that slip imports the height h1 of chamber 12, more preferably 1.2～3.0.
Grading plant of the present invention is separated into first by classification parts 16 and reclaims chamber 13 and the second recovery chamber 14, and, as long as have the space that slip can move towards the second recovery chamber 14 from the first recovery chamber 13, be not limited to above-mentioned structure.For example, also can dispose the classification parts 16 that possess the peristome that can stop up respectively.By the above-mentioned peristome of selecting to open wide, can change the classification point.Based on the reason identical with epimere, preferably arrive height till the bottom of the peristome that opens wide and import the ratio of height of chamber with respect to slip in 1.2～5.0 scope.
And, be used for adjusting slip S towards the boot speed guiding mechanism 18 of the boot speed of framework 11 by disposing at slip introducing port 12a and between as the pump P1 of hoisting mechanism, can further adjust the classification point.The above-mentioned boot speed guiding mechanism 18 of present embodiment comprises valve V1 and the pipe H3, the H4 that link with this valve V1.Make aforementioned tube H1 branch, at branch point connecting piece H3, pipe H4 and slurry vessel 22 link.Make the path branches between slip introducing port 12a and the pump P1, make one side with slip introducing port 12a binding and make the opposing party and valve V1 binding.Aperture by adjusting valve V1 also makes it unlimited, a part of returns stock tank 22 of the ormal weight of slip S.Therefore, can adjust slip S towards the boot speed of framework 11.
By reducing near the rate of climb of the slip first slurry level that reclaims in the chamber, can reduce the lower limit of classification point.But, when the reduction degree of the rate of climb surpasses when needing, can't obtain be used to making the minor diameter particle reclaim enough propulsive forces that move the chamber towards second.Therefore, in the present embodiment, select the rate of climb of above-mentioned slip from the scope of 0.003～0.050m/s.And as mentioned above, utilizing acceleration mechanism to make the speed of slip that imports the upper end of chamber by slip is 1.0～5.0m/s.Thus, can select the classification point from the scope of 50～300 μ m.
(shot-peening processing unit (plant))
Secondly, the situation that grading plant of the present invention is applied to the shot-peening processing unit (plant) of wet type is described.Fig. 4 illustrates the structure of the shot-peening processing unit (plant) 20 of wet type of the present invention.Shot-peening processing unit (plant) 20 comprises shot-peening Processing Room 21, be configured in the slurry vessel 22 of below of this shot-peening Processing Room and the sorting mechanism that the particle among the slip S in the slurry vessel 22 is carried out classification.And, be useful on the nozzle 23 that sprays slip S in the internal configurations of shot-peening Processing Room 21.
Store to have at slurry vessel 22 and be used in the abrasive particle (grinding-material) that carries out shot-peening processing and be dispersed in the slip S that (is water in the present embodiment) in the liquid and gets.Above-mentioned abrasive particle can be dry type, wet type, can be the particle of the common various particles that in shot-peening processing, can use such as iron and non-ion made of iron (steel ball, abrasive material, guiding principle silk cutting pill) ceramic-like particle, plant class particle, resinae particle and so on, there is no particular determination.Above-mentioned abrasive particle mixes, is dispersed in the water in the mode of 5～60 volume % that account for slip integral body.
In order to prevent that abrasive particle is settled down to the bottom of slurry vessel 22, as mentioned above, preferably dispose the rabbling mechanism (not shown) that makes its dispersion for stirring abrasive particle at above-mentioned slurry vessel 22.
Slip S in this slurry vessel 22 is drawn by hoisting mechanism P2 (being the shielding electrodynamic pump in the present embodiment) and carries towards the nozzle 23 that is configured in the shot-peening Processing Room 21.Be transported to the slip S of nozzle 23 and mix with the gases at high pressure that take place from gases at high pressure to send in source 24 (being compressed air in the present embodiment), spray towards machined object W as the solid and gas liquid three-phase fluid.The slip that sprays flows into above-mentioned slurry vessel 22.At this moment, the cutting particle by the machined object W that produced the abrasive particle of slight crack, breach with machined object W collision, produced by shot-peening processing etc. also flows into slurry vessel 22.In the processing of common shot-peening, can make the abrasive particle circulation and repeatedly use, but in above-mentioned generation in the abrasive particle of slight crack, breach, have the abrasive particle that becomes the diameter that is not suitable for shot-peening processing.That is, comprise the abrasive particle that becomes the diameter (can't reuse) that is not suitable for shot-peening processing and the cutting particle of machined object W etc. among the slip S in slurry vessel 22, therefore they need be removed.Therefore, when carrying out shot-peening processing in the above described manner, utilize above-mentioned sorting mechanism to carry out sorting.The abrasive particle returns stock tank 22 that can reuse that utilizes above-mentioned sorting mechanism to sub-elect, and sprayed by nozzle 23 at this.
Above-mentioned sorting mechanism can suitably use grading plant 10 of the present invention.That is, can will become the abrasive particle of the size that can't reuse, the cutting particle of machined object etc. as the minor diameter particle and separation respectively with the abrasive particle that can reuse among the slip S as the major diameter particle.The sauce that is dispersed with the abrasive particle that can reuse is discharged from and returns stock tank 22 from major diameter particle outlet 13a.On the other hand, the slip that is dispersed with the abrasive particle that becomes the size that can't reuse, the cutting particle of machined object etc. is discharged from from minor diameter particle outlet 14a.
Carried towards separating mechanism 25 from the slip that minor diameter particle outlet 14a is discharged from, carried out Separation of Solid and Liquid.Separation of Solid and Liquid can be used known method such as continuous sedimentation thickener, filter press, centrifugal separating device, sieve, magnetic force sorting unit.For example, abrasive particle and machined object all have under the situation of magnetic the situation of the burr of removing forging such as chrome-molybdenum steel (cold forging, forge hot) as abrasive particles such as using iron abrasive material, preferably use magnetic grader.
Utilize separating mechanism 25 isolated solids to reclaim as deposit.Isolated solid is recovered to deposit groove 26 as deposit.Isolated liquid is stored in hopper 27.This liquid can be in the concentration that is used for adjusting slip when slurry vessel 22 replenishes the abrasive particle of the decrement along with the carrying out of shot-peening processing.Perhaps, also can be for the machined object W after the cleaning shot-peening completion of processing.Clean with nozzle 28 by utilizing hoisting mechanism P3 that this liquid is sent into, and spray towards machined object with the gases at high pressure that take place from gases at high pressure to send in source 24, can remove abrasive particle and the cutting particle on the surface that remains in machined object W.
Can make hoisting mechanism P1 and hoisting mechanism P2 is same hoisting mechanism.For example, as shown in Figure 5, under the situation of only using hoisting mechanism P1, make pipe H1 branch, and this branch point can be linked to nozzle 23 via pipe.At this moment, also can be in that the configuration of 23 path be used for adjusting slip S towards the emitted dose guiding mechanism 29 of the import volume of nozzle 23 from this branch point to nozzle.For example, this emitted dose guiding mechanism 29 can use at one end to link has valve V2 and the other end to be configured near the slurry vessel 22 body.When opening this valve V2, therefore slip S returns stock tank 22 can adjust slip S towards the boot speed of nozzle 23 by the aperture of adjusting this valve.
And, as mentioned above, also can be used for adjusting slip S towards the boot speed guiding mechanism 18 (with reference to (A) of Fig. 1) of the boot speed of grading plant 10 in pipe H1 configuration.
When adjusting slip S towards the boot speed of grading plant 10 and towards the import volume of nozzle 23, under situation about need as valve, finely tune, also can replace valve and use diameter less than the body (throttle pipe) of above-mentioned body.Because the internal structure complexity of valve, therefore there are the misgivings that break down in the situation as the big slip S of use wearing and tearing.The failure ratio valve of throttle pipe is few, is difficult to carry out even if inner wearing and tearing increase the weight of under the situation of adjustment of boot speed of slip S, owing to than valve cheapness, therefore can easily change.
Though also not shown, stable in order to make the shot-peening working ability, also can dispose the densimeter for the concentration of measuring slip.Thereby can be according to the measurement result of densimeter and automatically or manually drop into the constant concentration that abrasive particle or liquid make slip towards slurry vessel.
As first embodiment, illustrate utilize grading plant of the present invention to mix iron abrasive material (GH-3: average grain diameter 300 μ m) and white fused alumina (WA#320: average grain diameter 40 μ m) slip that forms carries out the result of classification.For slip, the mode that is respectively 40 volume %, 10 volume % with the containing ratio of solids (abrasive particle) is scattered in water and is made into slip, imports the grading plant of present embodiment and carries out classification so that the flow velocity of the slip at slip introducing port place is the mode of 2.5m/s.Making from the slip of major diameter particle outlet and the discharge of minor diameter particle outlet is respectively the sieve of 125 μ m by the mesh opening, confirms to judge whether be classified into major diameter particle and minor diameter particle by the color of the slip behind this sieve by visualization.
Utilize sieve that the slip of discharging from major diameter particle outlet is carried out classification, results verification has a large amount of iron abrasive materials at sieve.And, though by the slip gonorrhoea slightly behind this sieve, be similar to water white transparency, therefore as can be known, only mix that the minor diameter particle of trace is arranged is white fused alumina.And, utilize sieve that the slip of discharging from minor diameter particle outlet is carried out classification, there is iron abrasive material in results verification at sieve.And, be the gonorrhoea shape by the slip behind the sieve, therefore mix, be dispersed with a large amount of white fused aluminas as can be known.According to above result as can be known, can utilize the grading plant of present embodiment to carry out classification accurately.
Secondly, as second embodiment, the example of situation that the grading plant of present embodiment is used as the sorting unit of shot-peening processing unit (plant) is described.Make iron abrasive material (GH-3: be that the mode of 30 quality % is scattered in the slip that water forms with concentration average grain diameter 300 μ m) as slip.The nozzle that utilizes aspiration-type sprays this slip and carry out shot-peening processing towards chromium steel steel (SCr).Nozzle is 100mm to the distance of machined object, and the pressure of hoisting mechanism P1 is 0.33MPa, and the pressure of gases at high pressure (compressed air) is 0.4MPa.
The angle of inclination of slip importing parts 15, the height of acceleration components 19 are changed by the mode of table 1 respectively with respect to the ratio (h3/h1) that slip imports the height of chamber, and carry out shot-peening processing.After injection, through 30 minutes the moment, reclaim slip respectively from major diameter particle outlet 13a and minor diameter particle outlet 14a.At 90 ℃ the slip that reclaims is carried out drying, utilize laser diffraction formula particle size distribution device (SALD-2100: Shimadzu Seisakusho Ltd.'s (strain) system) measure size distribution then.Calculate the effectiveness of classification κ (D75/D25) of classification point and major diameter particle based on the size distribution that is measured to.
Table 1
The height that imports the angle of inclination of parts 15 and acceleration components 19 by the change slip imports the ratio (h3/h1) of the height of chamber with respect to slip, can change the classification point.Usually, if effectiveness of classification κ is more than 1.0 then can carry out classification well, if more than 1.5 then can carry out classification admirably.The effectiveness of classification of embodiment 1～13 presents good result all more than 1.2.And, using under the situation of grading plant as the sorting unit of shot-peening processing unit (plant), so that minor diameter particle (becoming the abrasive particle of the size that can't reuse, the cutting particle of machined object etc.) is removed as purpose from slip.Therefore, under situation about the classification point being set at about 90 μ m, shown in embodiment 5, effectiveness of classification κ is 1.60.This illustrates that grading plant of the present invention can use well as the device of doing all one can of shot-peening processing unit (plant).
