Secondly, by making hoisting mechanism P1 work, slip S is imported in framework 11 from above-mentioned slip introducing port 12a.The flow velocity of slip S has to be elected solids as and can not import sedimentation in room 12 at slip and the 0.5 ~ 5m/s that can not impact classification.
For the slip S be imported into from slip introducing port 12a, solids condense each other and form agglomerate (offspring) sometimes.Grading plant of the present invention is that the difference of the sinking speed utilizing solids is to carry out classification.If minor diameter particle forms agglomerate each other, and when this agglomerate has major diameter particle equal above sinking speed, then this agglomerate is recovered together with major diameter particle, and therefore effectiveness of classification is deteriorated.Therefore, preferably fragmentation carried out to the agglomerate of minor diameter particle and become single particle (primary particle).Importing room 12 by forming slip as in the present embodiment, fragmentation can be carried out to the offspring of minor diameter particle.And then when slip S imports the upper end of room 12 by slip and flows into the first recovery room, minor diameter particle becomes primary particle.
In order to carry out fragmentation more reliably, the mode preferably expanded along with the upper direction in (A) of trend Fig. 1 with the sectional area making slip import the cross section (cross section of the paper vertical direction in (A) of Fig. 1) of room 12 configures slip introduction part 15.When the inflow of slip S is positioned at above-mentioned scope, the ratio (S1/S2) of the sectional area S1 of position that the area of preferred above-mentioned cross section is maximum and the sectional area S2 of minimum position is 2.5 ~ 5.0, is more preferably 3.0 ~ 4.0.Such as, the slip introduction part 15 on the right side in (B) of Fig. 1 can be made from plumbness towards right to tilt 2 ~ 8 ° (being preferably 2 ~ 4 °), by making the slip introduction part 15 of above-below direction side erect setting in the mode do not tilted, the sectional area of cross section can be expanded.When above-mentioned inclination is lower than 2 °, cannot broken offspring fully.When above-mentioned be tilted beyond 8 ° time, the stream of slip is peeled off by from slip introduction part 15, and therefore the stream of slip becomes unstable.In the present embodiment, above-mentioned inclination is set as 4 °.Thus, the effectiveness of classification κ (D75/D25) reclaiming first the major diameter particle that room is recovered is 1.20 ~ 1.75.In addition, effectiveness of classification κ (D75/D25) refers to that the bottom 1/4 relative to upper 1/4 value (particle that particle diameter is greater than this particle diameter is the particle diameter of 25% of accumulative size-frequency curve) is worth the ratio of (same as described above, to be the particle diameter of 75%).
In addition, so-called " sectional area expands along with trend top " can be not only situation about expanding continuously along with trend top, also can be a part has same cross-sectional continuously shape along with trend top.Such as, can be formed as making sectional area expand continuously along with above trend from bottom, then there is along with trend top the shape of same cross-sectional continuously.
Further, in order to improve effectiveness of classification or make the higher limit of classification point increase, preferably near the upper end of slip importing room 12, acceleration mechanism is configured.Acceleration mechanism preferably can accelerate the speed of slip S while the stream not upsetting slip S.In the present embodiment, as shown in Figure 3, acceleration components 19 triangular in shape for longitudinal section is configured in slip in the mode that the sectional area of its cross section expands along with trend top to import near the upper end of room 12.In addition, make near the upper end of slip introduction part 15 vertical.At the sloping portion 15a by slip introduction part 15 along with above trend after expanding the sectional area of cross section, by the acceleration mechanism be made up of the vertical component 15b of acceleration components 19 and slip introduction part 15, the sectional area of cross section is reduced gradually along with trend upper end.By acceleration mechanism, accelerated by the flow velocity of slip S during slip importing 12 upper end, room, therefore the rectilinear propagation of minor diameter particle improves.Therefore, minor diameter particle is easy to move to the second recovery room.When minor diameter particle does not move to the second recovery room and is stranded in the first recovery room for a long time, there is minor diameter particle coacervation and form offspring and reclaim the misgivings of room sedimentation first.By accelerating the flow velocity of slip S, the cohesion of minor diameter particle can be prevented, effectiveness of classification κ can be improved.For acceleration mechanism, the flow velocity of slip S can be accelerated by the parts of other shapes of configuration, also can be formed slip by the mode narrowed near upper end with the sectional area making slip import room 12 and import the sidewall of room 12 and accelerate the flow velocity of slip S.
Further, when the flow velocity of slip S is fast, the major diameter particle of sinking speed block is easily made to move to the second recovery room.As mentioned above, by the flow velocity utilizing acceleration mechanism to accelerate slip S, the higher limit of classification point can be improved.
In addition, so-called classification point refers to: the distribution of the size distribution (measuring relative to the pen amount (Pen of particle diameter) of minor diameter particle in a fractionated and major diameter particle) in, the particle diameter identical in quality of major diameter particle and minor diameter particle.
The speed preferably utilizing above-mentioned acceleration mechanism to make slip be imported the upper end of room 12 by slip is 1.0 ~ 5.0m/s.When this speed is lower than 1.0m/s, the effect of acceleration mechanism cannot be obtained.When this speed is more than 5.0m/s, can upset the stream of the slip of the first recovery indoor, effectiveness of classification reduces.Further, due to the rate of climb of the slip of slurry level hope place in the first recovery room can be improved, therefore, it is possible to obtain fully for making minor diameter particle reclaim the propulsive force of room movement towards second.As a result, the higher limit of classification point can be made to increase.By selecting the speed of slip from above-mentioned scope, classification point can be adjusted, and can high-precision classification be carried out.
Further, the height h3 of deceleration component 19 is preferably 0.2 ~ 1.0 relative to the ratio (h3/h1) of the height h1 of slip importing room 12.When lower than 0.2 time, the acceleration distance of slip is not enough, and slip S therefore cannot be made to accelerate fully.Therefore, the higher limit of classification point diminishes, and the adjusting range of classification point narrows.When more than 1.0, the wall surface resistance that the boundary between acceleration mechanism and slip S produces becomes greatly, and therefore the acceleration of particle is hindered.
Weak in the adhesion of offspring, can easily broken, the sectional area that slip also can be made to import room 12 expands gradually along with trend top.Even if in this case, also room 12 can be imported at slip as required configure above-mentioned acceleration mechanism.
Import the slip S behind room 12 by slip and flow into the first recovery room 13.When first reclaim room be full of slip S time, the fast major diameter particle of sinking speed sinks down into the bottom of the first recovery room.On the other hand, the minor diameter particle that sinking speed is slow is trapped near the liquid level of slip S.
When the first amount reclaiming the slip S of room constantly increases, liquid level crosses the upper end of above-mentioned classification parts 16, slip S flows into second by the gap formed by the upper end of these classification parts 16 and the top of framework 11 and reclaims room 14.Thus, reclaim room 14 at the first minor diameter particle reclaimed near the liquid level being trapped in slip S in room 13 towards second to move.
Then, above-mentioned major diameter particle dump valve and above-mentioned minor diameter particle dump valve is opened, the slip utilizing grading plant to reclaim respectively to be dispersed with major diameter particle and be dispersed with the slip of minor diameter particle.Now, to make the discharge rate (flow of slip) from major diameter particle outlet 13a and minor diameter particle outlet 14a become the adjustment that suitable mode carries out flow.Such as, when too much from the discharge rate of major diameter particle outlet 13a, slip S does not reclaim room towards second and moves.On the contrary, when very few, the mobile quantitative change towards the second recovery room is many, result, and particle diameter is greater than the particle reclaiming the target grain size that room is reclaimed second and moves towards the second recovery room.
Near the bottom of the first recovery room 13 and the second recovery room 14, along with trend major diameter particle outlet 13a and minor diameter particle outlet 14a, the sectional area of cross section reduces respectively.Therefore, major diameter particle and minor diameter particle can not be deposited in the bottom of the first recovery room 13 and the second recovery room 14, but are discharged by from framework 11 efficiently.
When the area that first reclaims the cross section of room 13 is crossed wide, minor diameter particle implemented 13 sedimentations before room 14 is reclaimed in arrival second after first, and when narrow, major diameter particle collided with above-mentioned classification parts 16 before sedimentation.Therefore, the first sectional area S3 reclaiming the cross section of room at the top place of preferred above-mentioned slip importing room 12 selects from 2 ~ 10 relative to the ratio (S3/S2) of the sectional area S2 of the cross section of above-mentioned slip importing room 12.
Grading plant of the present invention can easily change classification point by the interval of changing between above-mentioned classification parts 16 and above-mentioned top board.In the present embodiment, by the structure that is formed as loading and unloading by classification parts 16 and the different classification parts 16 of the height (above-below direction in (A) of Fig. 1) that changes the outfit, can easily make classification o'clock at the scope change of 100 ~ 1000 μm.When the top that slip imports room 12 is too small with the difference of the height and position of the top of classification parts 16, major diameter particle is also admitted to the second recovery room 14, and when above-mentioned difference is excessive, the height of framework 11 becomes too high.Therefore, the height h2 of preferred above-mentioned classification parts 16 is 1.2 ~ 5.0 relative to the ratio (h2/h1) of the height h1 of slip importing room 12, is more preferably 1.2 ~ 3.0.
Grading plant of the present invention is separated into the first recovery room 13 and second by classification parts 16 and reclaims room 14, and, as long as there is slip can reclaim the space of room 13 towards the second recovery room 14 movement from first, be not limited to above-mentioned structure.Such as, the classification parts 16 possessing the opening portion that can block respectively can also be configured.By selecting the above-mentioned opening portion opened wide, classification point can be changed.Based on the reason identical with epimere, preferably to open wide opening portion bottom height relative to slip import room height ratio 1.2 ~ 5.0 scope.
Further, adjusting the boot speed guiding mechanism 18 of slip S towards the boot speed of framework 11 by being configured between slip introducing port 12a and the pump P1 as hoisting mechanism, classification point can be adjusted further.Pipe H3, H4 that the above-mentioned boot speed guiding mechanism 18 of present embodiment comprises valve V1 and links with this valve V1.Make above-mentioned pipe H1 branch, link at branch point connecting piece H3, pipe H4 and slurry vessel 22.Make the path branches between slip introducing port 12a and pump P1, make one side and slip introducing port 12a link and the opposing party and valve V1 are linked.Make it unlimited, a part of returns stock tank 22 of the ormal weight of slip S by the aperture of regulating valve V1.Therefore, it is possible to adjustment slip S is towards the boot speed of framework 11.
By reducing the rate of climb of the slip near the slurry level in the first recovery room, the lower limit of classification point can be reduced.But, when the reduction degree of the rate of climb exceed need time, cannot obtain for making minor diameter particle reclaim enough propulsive forces of room movement towards second.Therefore, in the present embodiment, the rate of climb of above-mentioned slip is selected from the scope of 0.003 ~ 0.050m/s.Further, as mentioned above, acceleration mechanism is utilized to make the speed being imported the slip of the upper end of room by slip be 1.0 ~ 5.0m/s.Thereby, it is possible to select classification point from the scope of 50 ~ 300 μm.
(blasting apparatus)
Secondly, the situation of blasting apparatus grading plant of the present invention being applied to wet type is described.Fig. 4 illustrates the structure of the blasting apparatus 20 of wet type of the present invention.Blasting apparatus 20 comprises shot-peening Processing Room 21, is configured in the slurry vessel 22 of the below of this shot-peening Processing Room and the particle in the slip S in slurry vessel 22 carried out to the sorting mechanism of classification.Further, the nozzle 23 for spraying slip S is configured with in the inside of shot-peening Processing Room 21.
Abrasive particle (grinding-material) dispersion (being water in the present embodiment) and the slip S that obtains in a liquid being used in and carrying out shot-peening processing is had at slurry vessel 22.Above-mentioned abrasive particle can be dry type, wet type, can be the various particles that usually can use in shot-peening processing as the particle of iron and non-ion made of iron (steel ball, abrasive material, guiding principle silk cutting pill) ceramic-like particle, plant particle, resinae particle and so on, there is no particular determination.Above-mentioned abrasive particle mixes in the mode of 5 ~ 60 volume % accounting for slip entirety, is dispersed in water.
In order to the bottom preventing abrasive particle to be settled down to slurry vessel 22, as mentioned above, be preferably configured with at above-mentioned slurry vessel 22 rabbling mechanism (not shown) making it disperse for stirring abrasive particle.
Slip S in this slurry vessel 22 is drawn by hoisting mechanism P2 (being shielding electrodynamic pump in the present embodiment) and is carried towards the nozzle 23 be configured in shot-peening Processing Room 21.The slip S being transported to nozzle 23 mixes with the gases at high pressure sent into from gases at high pressure occurring source 24 (being compressed air in the present embodiment), sprays towards machined object W as solid and gas liquid three-phase fluid.The slip sprayed flows into above-mentioned slurry vessel 22.Now, create slight crack by colliding with machined object W, the abrasive particle of breach, the cutting particle etc. of being processed the machined object W produced by shot-peening also flow into slurry vessel 22.In common shot-peening processing, abrasive particle can be made to circulate and repeatedly use, but create in the abrasive particle of slight crack, breach above-mentioned, there is the abrasive particle becoming the diameter being not suitable for shot-peening processing.That is, comprise the abrasive particle of diameter (cannot reuse) and the cutting particle etc. of machined object W that become and be not suitable for shot-peening processing in the slip S in slurry vessel 22, therefore need them to remove.Therefore, while carrying out shot-peening processing in the above described manner, above-mentioned sorting mechanism is utilized to carry out sorting.The abrasive particle returns stock tank 22 that can reuse utilizing above-mentioned sorting mechanism to sub-elect, and sprayed by nozzle 23 at this.
Above-mentioned sorting mechanism suitably can use grading plant 10 of the present invention.That is, can using the abrasive particle that can reuse in slip S as major diameter particle, using becoming the abrasive particle of the size that cannot reuse, the cutting particle etc. of machined object is separated respectively as minor diameter particle.The sauce being dispersed with the abrasive particle that can reuse is discharged and returns stock tank 22 from major diameter particle outlet 13a.On the other hand, be dispersed with become the size that cannot reuse abrasive particle, machined object the slip of cutting particle etc. be discharged from minor diameter particle outlet 14a.
The slip be discharged from minor diameter particle outlet 14a is carried by towards separating mechanism 25, carries out Separation of Solid and Liquid.Separation of Solid and Liquid can use the known methods such as continuous sedimentation thickener, filter press, centrifugal separating device, sieve, magnetic force sorting device.Such as, under abrasive particle the situation of the burr as forging (cold forging, forge hot) such as abrasive particle removing chrome-molybdenum steel such as the iron abrasive materials of use and the magnetic situation of the equal tool of machined object, preferably magnetic grader is used.
The isolated solids of separating mechanism 25 are utilized to reclaim as deposit.Isolated solid is recovered to deposit groove 26 as deposit.Isolated liquid storage is in hopper 27.This liquid can supplementing towards slurry vessel 22 along with the carrying out of shot-peening processing during the abrasive particle of decrement for adjusting the concentration of slip.Or, also may be used for the machined object W after cleaning shot-peening completion of processing.By utilizing hoisting mechanism P3 that this liquid is sent into cleaning nozzle 28, and spraying towards machined object together with the gases at high pressure sent into from gases at high pressure occurring source 24, the abrasive particle on the surface remaining in machined object W can be removed and cut particle.
Hoisting mechanism P1 and hoisting mechanism P2 can be made to be same hoisting mechanism.Such as, as shown in Figure 5, when only using hoisting mechanism P1, Shi Guan H1 branch, and this branch point can be linked to nozzle 23 via pipe.Now, also the emitted dose guiding mechanism 29 of adjustment slip S towards the import volume of nozzle 23 can be configured for from this branch point to the path of nozzle 23.Such as, this emitted dose guiding mechanism 29 can be used in one end and be linked with valve V2 and the other end is configured in body near slurry vessel 22.When opening this valve V2, slip S returns stock tank 22, therefore, it is possible to adjust the boot speed of slip S towards nozzle 23 by the aperture adjusting this valve.
Further, as mentioned above, also the boot speed guiding mechanism 18 ((A) with reference to Fig. 1) of adjustment slip S towards the boot speed of grading plant 10 can be configured at pipe H1.
When adjusting the boot speed of slip S towards grading plant 10 and the import volume towards nozzle 23, when needing to carry out finely tuning as valve, also can replace valve and use diameter to be less than the body (throttle pipe) of above-mentioned tubular body.Because the internal structure of valve is complicated, therefore when using the situation of the large slip S of wearing and tearing to there are the misgivings broken down.The failure ratio valve of throttle pipe is few, even if the increased wear of inside and be difficult to the adjustment of the boot speed carrying out slip S when, due to more cheap than valve, therefore, it is possible to easily change.
Although and not shown, in order to make shot-peening working ability stablize, also can be configured for the densimeter of concentration measuring slip.Can automatically or manually drop into abrasive particle or liquid towards slurry vessel according to the measurement result of densimeter thus make the constant concentration of slip.
As the first embodiment, illustrate and utilize grading plant of the present invention to carry out the result of classification to the slip mixing iron abrasive material (GH-3: average grain diameter 300 μm) and white fused alumina (WA#320: average grain diameter 40 μm).For slip, be respectively 40 volume % with the containing ratio of solids (abrasive particle), the mode of 10 volume % is scattered in water and is made into slip, the mode being 2.5m/s with the flow velocity of the slip making slip introducing port place imports the grading plant of present embodiment and carries out classification.Make the slip of discharging from major diameter particle outlet and minor diameter particle outlet be the sieve of 125 μm respectively by mesh opening, confirm to determine whether to be classified into major diameter particle and minor diameter particle by the color of the slip after this sieve by visualization.
Utilize sieve to carry out classification to the slip of discharging from major diameter particle outlet, results verification has a large amount of iron abrasive materials on sieve.Further, although by the gonorrhoea slightly of the slip after this sieve, be similar to water white transparency, therefore known, only mix the minor diameter particle and white fused alumina that there are trace.Further, utilize sieve to carry out classification to the slip of discharging from minor diameter particle outlet, there is iron abrasive material in results verification on sieve.Further, be gonorrhoea shape by the slip after sieve, therefore knownly mix, be dispersed with a large amount of white fused aluminas.According to above result, the grading plant of present embodiment can be utilized to carry out classification accurately.
Secondly, as the second embodiment, the example of situation about being used as the sorting unit of blasting apparatus by the grading plant of present embodiment is described.Iron abrasive material (GH-3: average grain diameter 300 μm) is made to be scattered in the slip of water in the mode that concentration is 30 quality % as slip.The nozzle of aspiration-type is utilized to be sprayed towards chromium steel steel (SCr) by this slip and carry out shot-peening processing.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.
Make the angle of inclination of slip introduction part 15, the ratio (h3/h1) of height that the height of acceleration components 19 imports room relative to slip changes by the mode of table 1 respectively, and carry out shot-peening processing.After the injection through the moment of 30 minutes, reclaim slip respectively from major diameter particle outlet 13a and minor diameter particle outlet 14a.At 90 DEG C, drying is carried out to reclaimed slip, then utilize laser diffraction formula particle size distribution device (SALD-2100: Shimadzu Seisakusho Ltd.'s (strain) makes) to measure size distribution.The effectiveness of classification κ (D75/D25) of classification point and major diameter particle is calculated based on be measured to size distribution.
Table 1
Imported the ratio (h3/h1) of the height of room by the height at the angle of inclination and acceleration components 19 of changing slip introduction part 15 relative to slip, classification point can be changed.Usually, if effectiveness of classification κ is more than 1.0, classification can be carried out well, if more than 1.5, classification can be carried out admirably.The effectiveness of classification of embodiment 1 ~ 13, all more than 1.2, presents good result.Further, when the sorting unit using grading plant as blasting apparatus, so that minor diameter particle (becoming the cutting particle etc. of the abrasive particle of the size that cannot reuse, machined object) is removed as object from slip.Therefore, when classification point is set as about 90 μm, as described in Example 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 blasting apparatus.
