Like Fig. 4 and shown in Figure 7, in this embodiment, return port 17 cylindraceous is to be arranged at the central part of the front wall portion 2 of this housing 1 with housing 1 concentric shape.

Like Fig. 4～shown in Figure 7, mix and be positioned at return port 17 under introducing port 11 comprises concentric 2 endless grooves 10 in inside with the peristome to this housing 1 inner opening the state of a circumferential part and be arranged at front wall portion 2 with respect to the mode of the horizontal side of the peristome of housing 1.When in addition, mixing introducing port 11 and observe to overlook axle center A2 parallel with the axle center A3 of housing 1 and from the horizontal direction observation of the axle center A3 quadrature of housing 1 time axle center A2 be arranged at the front wall portion 2 of housing 1 the closer to the inclination attitude down of the axle center A3 of housing 1 the closer to the front wall portion 2 of housing.By the way, as stated, mixing introducing port 11 is about 45 degree with respect to the angle of inclination down of horizontal direction.

Like Fig. 4 and shown in Figure 7, stator 7 is installed on the inner surface (with rotor 5 opposed faces) of the front wall portion 2 of housing 1, and the front wall portion 2 that is fixed into housing 1 becomes one with stator 7.

In addition, as shown in Figure 5, the mode that discharge opening 12 extends with the tangential direction of outside surrounding wall portion 4 is arranged at this cylindric periphery wall portion 4.

Like Fig. 6～shown in Figure 9; In this embodiment, respectively scrape slice 9 and form bar-shapedly, and be fixed into this bar-shaped base end part 9B that scrapes slice 9 and the rotation of rotor 5 one with inclination attitude; And rotor 5 drives to direction (direction of representing with arrow Fig. 4～Fig. 6) rotation that the front end of when its axis direction is observed, scraping slice 9 becomes the front side; Wherein said inclination attitude is, during from the radially observation of rotor 5, this bar-shaped front of scraping slice 9 is offside in front wall portion 2 sides; And when the axis direction of rotor 5 is observed, with the posture of the offside radially inner side in rotor 5 of this bar-shaped front of scraping slice 9.

Explain scraping slice 9 according to Fig. 5～Fig. 9.

Scrape slice 9 and constitute bar-shapedly, possess successively towards front end from cardinal extremity: be fixed in spacer body 15 base end part 9B, become the pars intermedia 9M that is exposed to the state that imports chamber 13, the leading section 9T that becomes the state that is embedded in (promptly stretching into) endless groove 10.

Like Fig. 5, Fig. 7, Fig. 8 (b) and shown in Figure 9, it is tabular that the base end part 9B that scrapes slice 9 constitutes essentially rectangular.

Like Fig. 5, Fig. 7, Fig. 8 (a) and Fig. 8 (b), and shown in Figure 9, and the pars intermedia 9M that scrapes slice 9 constitutes the roughly triangular column that shape of cross section is general triangular.And; As as stated, scrape slice 9 with the inclination attitude setting; Side 9m (the following diffusingsurface that is recited as sometimes) towards the direction of rotation front side of rotor 5 in three sides of the pars intermedia 9M of triangle column is the shape that leans forward of tilt before the direction of rotation of rotor 5, and with radially constituting towards the mode of radial outside (following be recited as sometimes oblique outside) with respect to rotor 5.

Promptly; Through the bar-shaped slice 9 of scraping being set with inclination attitude as as stated; This scrapes and is exposed to the radially foreign side that leading section 9T that the pars intermedia 9M that imports chamber 13 is positioned at than is embedded in endless groove 10 more leans on rotor 5 in the slice 9; And the diffusingsurface 9m towards the direction of rotation front side of this pars intermedia 9M is the shape that leans forward of tilt before the direction of rotation of rotor 5, and with respect to the radially oblique outer incline of rotor 5.Thus, guide become during importing chamber 13 towards the radial outside of rotor 5 mobile from the pre-composition Fp that endless groove 10 scrapes according to the diffusingsurface 9m that scrapes the pars intermedia 9M of slice 9 through the leading section 9T that scrapes slice 9.

Like Fig. 6, Fig. 7, Fig. 8 (a) and Fig. 8 (b) and shown in Figure 9; The leading section 9T that scrapes slice 9 is the shape of cross section roughly quadrangular shape of shape in the form of a substantially rectangular; And constitute the arcuation that is following state: promptly when the axis direction of rotor 5 is observed; In four sides in 10 the inner surface towards lateral surface 9o along endless groove of the radial outside of rotor 5 towards the inner surface inwardly of radially inner side; And, in four sides towards the 9i of side inwardly of the radially inner side of rotor 5 inner surface outwardly in the inner surface of annulus 10 towards radial outside.

In addition; The 9f that appears that scrapes towards the direction of rotation front side of rotor 5 in four sides of quadrangular shape leading section 9T constitutes the shape that leans forward that is tilt before the direction of rotation of rotor 5, and with respect to rotor 5 radially towards radial outside (following be recited as sometimes oblique outside).

Thus, the 9f that appears that scrapes that the pre-composition Fp basis that scrapes from endless groove 10 through the leading section 9T that scrapes slice 9 is scraped the leading section 9T of slice 9 is discarded in the importing chamber 13 towards the radial outside of rotor 5.

And the front end face 9t that scrapes the leading section 9T of slice 9 constitutes and is embedded under the state of endless groove 10 parallel with the bottom surface of endless groove 10 at its leading section 9T.

Scrape slice 9 with aforesaid inclination attitude and upwards whenever base end part 9B is fixedly set in the ring-shaped flat board 15c of spacer body 15 respectively in week for 4 that constitute aforesaid shape at a distance from the spaced mode of 90 degree central angles; Thereby constitute the inboard slice row Li that scrapes; The outside of scraping slice row Li in this inboard; 4 scrape slice 9 with aforesaid inclination attitude and with week upwards every spaced mode at a distance from 90 degree central angles respectively base end part 9B is fixedly set in the ring-shaped flat board 15c of spacer body 15, thereby scrape slice row Lo outside constituting.

In addition; Scrape slice 9 and scrape slice row Li and upwards arranging in week when being provided with inboard for such 8 with per 4 the slice row Lo that scrape that are divided into the outside; For the phase place that makes progress in week that base end part 9B is fixed in the position of spacer body 15; The base end part 9B of inner column Li with respect to the base end part 9B of outer rows Lo along the direction of rotation of rotor 5 with 30 degree left and right sides central angles skews, inboard thus 4 of scraping slice row Li scrape the arrangement phase place of slice 9 and 4 arrangement phase deviations of scraping slice 9 of scraping slice row Lo in the outside.

As Fig. 6, Fig. 7, and Fig. 8 (a) and Fig. 8 (b) shown in; Thereby through as stated 8 scrape slice 9 with per 4 be divided into the outside scrape slice row Lo with inboard scrape slice row Li and upwards arrange in week be provided with constitute adjacent 4 of scraping slice row Lo, Li scrape slice 9 week upwards with when the axis direction of rotor 5 is observed, the part of the base end side of scraping slice 9 of inner column Li (being the part of the base end side of base end part 9B and pars intermedia 9M) and set with this overlapping mode of part (being leading section 9T) of scraping the front of scraping slice 9 of the corresponding outer rows Lo of slice 9.

As shown in Figure 4; The spacer body 15 of scraping slice row Lo, Li that is provided with 2 row as stated is installed on the front surface of rotor 5 with the front surface through interval holding member 20 and rotor 5 across state at interval, and the rotor 5 that spacer body 15 is installed like this can slip the state that is embedded in return port 17 rotatably with the tubular slide connecting part 15a of spacer body 15 and be equipped in the housing 1.

So; Between the back surface of the front surface of heaving shape of rotor 5 and spacer body 15, form the return chamber 14 of the more little tapered of the front wall portion 2 side diameters of housing 1, constitute return port 17 and be communicated with return chamber 14 by means of the tubular slide connecting part 15a of spacer body 15.

In addition, between the front surface of the front wall portion 2 of housing 1 and spacer body 15, form the importing chamber 13 of the ring-type that is communicated with mixing introducing port 11.

And; Constitute as follows: if rotation drives rotor 5; Then spacer body 15 rotates with state and the rotor 5 that tubular slide connecting part 15a and return port 17 slip integratedly, even under the state of rotor 5 and spacer body 15 rotations, also keep the state that return port 17 is communicated with return chamber 14 by means of the tubular slide connecting part 15a of spacer body 15.

Separator 70 constitutes in cylindrical container 71 according to proportion separate dissolved liquid; As shown in Figure 1; Constitute the not dissolving slurry Fr that will comprise the state of not consoluet powder P respectively and be separated to circulation road 16 from the slurry F that supplies with via the road 18 that spues by the portion that spues 12 of dispersal device Y, with powder P roughly the slurry F of consoluet state be separated to and discharge road 22.Spue road 18 and circulation road 16 is connected with the bottom of cylindrical container 71 respectively, discharges road 22 and is connected with the top of cylindrical container 71 and the supply end 80 of slurry F (product).

In addition; Though it is not shown; But separator 70 is constructed as follows, and it is outstanding to inside from the bottom surface of cylindrical container 71 promptly to set the importing pipeline that connects the road 18 that spues, and possesses the discharge portion that discharges road 22 that is connected on the top of cylindrical container 71; And possess the circulation portions that is connected in circulation road 16 in the bottom, set in the upper end that spues that imports pipeline and make from importing the mobile blade that circles round of the lysate that pipeline spues.

Then, the action to this powder dissolution system describes.

At first, under the state of the attraction that stops the powder P that weigh feeder X, closed shutter valve 46 stop to produce by means of powder discharge pipe 45, only make rotor 5 rotations donor solvent R the time from solvent supplying apparatus 50, dispersal device Y brings into operation.If become negative pressure state (for example, the vacuum state about-0.06MPa) in the dispersal device Y, then open gate valve 46 through predetermined running time.Thus, the expanding chamber 47 of weigh feeder X is made as negative pressure state (about 0.06MPa), makes becoming the pressure state between this negative pressure state and the atmospheric pressure state near the 31b of lower openings portion of the inside of importing portion 41 and hopper 31.

And; Start weigh feeder X, according to the negative pressure suction force of the stirring action of stirring vane 32A and dispersal device Y will be stored in the hopper 31 powder P from the 31b of lower openings portion of hopper 31 via expanding chamber 47 predetermined amounts of weight feed mechanism 40 one by one continuous and quantitative supply to the hydrid component 61 of mixed organization 60.Meanwhile, start solvent feed mechanism 50, solvent R predetermined amounts continuous and quantitative is supplied to the hydrid component 61 of mixed organization 60 according to the negative pressure suction force of dispersal device Y.

Powder P supplies to via the cylindrical portion 62 of hydrid component 61 from the hydrid component 61 of mixed organization 60 and mixes introducing port 11; And solvent R supplies to the state of fissureless hollow cylindrical eddy current via narrow annular channel 63 and mixes introducing port 11; Powder P and solvent R are by mixing introducing port 11 by premix, and its pre-composition Fp is directed into 2 endless grooves 10.

If rotor 5 is driven and spacer body 15 and the rotation at a high speed integratedly of this rotor 5 by rotation at a high speed, 2 row that then are arranged at this spacer body 15 with concentric shape are scraped separately 4 of slice row Lo, Li and are scraped slice 9 is embedded in the endless groove 10 corresponding with each row respectively with leading section 9T state high speed rotating.

So; As representing with solid arrow among Fig. 4 and Fig. 5; Introducing port 11 flows and the pre-composition Fp that is directed into 2 endless grooves 10 is scraped by the leading section 9T that scrapes slice 9 that is embedded in endless groove 10 and rotate mixing; The pre-composition Fp that this scrapes substantially in importing chamber 13 front surface of the infundibular segment 15b in the spacer body 15 mobile to the direction of rotation of rotor 5 simultaneously with the front surface of ring-shaped flat board 15c, and then, through the importing chamber side open-work 7a inflow wing chamber 8 of stator 7; Direction of rotation to rotor 5 in this wing chamber 8 flows, and spues from the portion of spuing 12.

The pre-composition Fp that is directed into 2 endless grooves 10 receives shear action when being scraped by the leading section 9T that scrapes slice 9.At this moment; Shear action act on the inboard scrape the leading section 9T that scrapes slice 9 among the slice row Li towards lateral surface 9o and inboard endless groove 10 inwardly between the inner surface, and outwardly between the inner surface of endless groove 10 of the inboard 9i of side inwardly that scrapes the leading section 9T that scrapes slice 9 among the slice row Li and inboard; And, shear action act on the outside scrape the leading section 9T that scrapes slice 9 among the slice row Lo towards the endless groove 10 in lateral surface 9o and the outside inwardly between the inner surface, and outside the 9i of side inwardly that scrapes the leading section 9T that scrapes slice 9 among the slice row Lo and outwardly between the inner surface of endless groove 10 in the outside.

That is, because 4 different zones that the footpath that can make shearing force act on rotor 5 makes progress, therefore abundant chopping pre-composition Fp, and can in the flowing of pre-composition Fp, fully produce turbulent flow and powder P is dissolved equably be mixed among the solvent R.

And, because 4 scraped on the same position that slice 9 makes progress along the footpath that circumferentially is equipped on rotor 5, therefore during rotor 5 rotates a circle; Shearing force is acted on the same position radially of rotor 54 times; And scraping among slice row Li, the Lo of inside and outside 2 row, 4 arrangement phase places that make progress in week of scraping slice 9 that constitute each row are different; So during rotor 5 rotates a circle, can be to import to 8 shearing forces of pre-composition Fp effect of 2 endless grooves 10 from mixing introducing port 11.

That is, the pre-composition Fp that import in the chamber 13 are produced pressure pulse with higher frequency, therefore further chopping pre-composition Fp, and can in the flowing of pre-composition Fp, further produce turbulent flow.

And the diffusingsurface 9m towards the direction of rotation front side of rotor 5 that appears 9f and scrape the pars intermedia 9M of slice 9 towards scraping of the direction of rotation front side of rotor 5 that scrapes the leading section 9T of slice 9 is the shape that leans forward, and is oblique outer shape.

Thus; The pre-composition Fp that leading section 9T through scraping slice 9 scrapes from endless groove 10 appears 9f according to scraping of the leading section 9T that scrapes slice 9 and toward the radial outside of rotor 5 and be discarded to guide and enter the room in 13, the pre-composition Fp that emits so further guides in importing chamber 13 mobile towards the radial outside of rotor 5 by the diffusingsurface 9m of the pars intermedia 9M that scrapes slice 9.And; Pre-composition Fp is through importing chamber side open-work 7a; And shredded also receiving shearing force when the side open-work 7a of this importings chamber, and the rotation wing 6 through rotation at a high speed further receives shear action and quilt is shredded; Generate the fully slurry F of dissolving powder P, and from discharge opening 12 this slurry F that spues.

That is, mix from mixing introducing port 11 importing to the pre-composition Fp that imports in the chamber 13 when can suppress to be detained well, and spue from discharge opening 12 as slurry F.

And; When the axis direction of rotor 5 is observed; The base end part 9B that respectively scrapes slice 9 of inner column Li and overlapping with the leading section 9T that respectively scrapes slice 9 that respectively scrapes the corresponding outer rows Lo of slice 9 of this inner column Li; Therefore between the leading section 9T that scrapes slice 9 of the base end part 9B that scrapes slice 9 that is pressed into inner column Li of the pre-composition Fp that scrapes the radial outside that slice 9 scraped and moved to rotor 5 through inner column Li and outer rows Lo and therefore effect by compression can promote chopping and the dissolving mixing of pre-composition Fp.

In a word; 4 different zones that can make progress in the footpath of rotor 5 act on from mixing the pre-composition Fp that introducing port 11 is directed into 2 endless grooves 10 shearing force; And in importing chamber 13, pre-composition Fp is produced pressure pulse with higher frequency; Therefore pre-composition Fp is shredded and is dissolved mixing, generates the few slurry F of agglomerate, this slurry F with after the slurry F that states from return chamber 14 mix and spue from discharge opening 12.

The slurry F that spues from discharge opening 12 supplies to separator 70 via the road 18 that spues; In separator 70; What separate into the state that comprises not consoluet powder P does not dissolve the roughly slurry F of consoluet state of slurry Fr and powder P; Do not dissolve slurry Fr and supply to separator Y once more via circulation road 16, slurry F supplies to supply end 80 via discharging road 22.

Do not dissolve slurry Fr and import to return chamber 14 from return port 17; A plurality of stirring vanes 21 through rotation at a high speed in this return chamber 14 receive shear action and further chopping of quilt; And through the side open-work 7b of return chamber the time, also receive shear action and by being shredded, and the rotation wing 6 through rotation at a high speed receives shear action and is shredded; The slurry F that agglomerate further reduces mixes with slurry F from importing chamber 13, and spues from discharge opening 12.

The delay that therefore, can suppress effectively in the dispersal device Y to generate effectively the slurry F that does not almost have agglomerate that powder P dissolves equably.

Then, according to Figure 10～Figure 12, and Figure 13 (a) can promote powder P to describe as the collocating structure of scraping slice 9 through adopting collocating structure involved in the present invention to checking to Figure 13 (c) with the checking result that the dissolving of solvent R mixes.

In addition; Figure 10～Figure 12 is the figure that emulation imports the flow regime of the pre-composition Fp in the chamber 13, be illustrated in through near the peristome of endless groove 10 and with the cross section of the axle center A3 quadrature of housing 1 in pre-composition Fp with respect to the velocity that flows relatively of the rotation velocity vector of the rotation wing 6.But, also show the velocity that flows relatively of the pre-composition Fp that has in the return chamber 14 among Figure 10～Figure 12.

In addition; Figure 13 (a) to Figure 13 (c) be the figure that emulation imports the pressure distribution of the pre-composition Fp in the chamber 13, be illustrated in the approximate centre of the peristome through mixing introducing port 11 and comprise the interior pressure distribution of importing chamber 13 and return chamber 14 in the cross section of axle center A3 of housing 1 with the depth of color.That is, the shallow more pressure of color is low more.

Figure 10 and Figure 13 (a) expression forms 2 row with concentric shape and scrapes slice row Li, Lo; And in respectively scraping slice row Li, Lo, upwards scrape slice 9 uniformly-spaced to set 4 in week; And set the mode (following omission sometimes is recited as 2 row different phases and sets mode) of scraping slice 9 with different arrangement phase places inside and outside scraping among slice row Li, the Lo; That is, at the simulation result in the mode that sets of this embodiment.In addition; When Figure 11 and Figure 13 (b) expression forms 2 row and scrapes slice row L with concentric shape, and at the inside and outside simulation result that sets with identical arrangement phase place in the mode (the following 2 row same-phases that elliptically are recited as sometimes set mode) of scraping slice 9 of scraping among slice row Li, the Lo.In addition; Figure 12 and Figure 13 (c) expression is upwards being arranged a plurality of modes that set (following omission sometimes is recited as 1 row and sets mode) of scraping slice 9 that set week with the state (row) of the same position that the footpath that is positioned at rotor 5 makes progress; That is, in the past set the simulation result in the mode.

If pay close attention to the zone of irising out with circle among Figure 10～Figure 12; Then can learn as follows; That is, set mode and compare with 1 row, 2 row different phases set mode and 2 row same-phases and inwardly set in the mode towards the footpath of rotor 5 that the bigger velocity of component of side increases; Set mode and set and scrape slice 9 through set mode or 2 row same-phases with 2 row different phases, can promote the turbulent flow of the flow regime of the pre-composition Fp in importing chamber 13.

If pay close attention to the zone that Figure 13 (a) irises out with circle to Figure 13 (c); Then can learn as follows; That is, near peristome, set mode with 1 row and compare with respect to the mixing introducing port 11 that imports chamber 13; 2 row different phases set mode and 2 row same-phases and set and all become the bigger distribution of pressure oscillation in the mode, can strengthen the pressure pulse that imports the pre-composition Fp in the chamber 13.That is, can learn to import in the chamber 13 and become further low pressure.

In addition; Compare with Figure 13 (b); Can learn as follows by Figure 13 (a); Promptly the 2 row different phases generation number of times (frequency) that sets the pressure pulse of mode sets the generation number of times of the pressure pulse of mode greater than 2 row same-phases, and the fluctuation of the pressure in the zone of irising out with circle is compact, therefore further promotes the turbulent flow of the flow regime of pre-composition Fp.

Through above-mentioned checking; Can learn as follows, that is, and like the present invention; Rotor 5 diverse location diametrically possesses a plurality of slices 9 of scraping; Endless groove 10 and the footpath of rotor 5 make progress diverse location possessed respectively that to scrape slice 9 corresponding and be provided with a plurality ofly with concentric shape, can promote to shred the effect of pre-composition Fp thus and in the flowing of pre-composition Fp, produce turbulent effect, thereby can improve the mixed of dispersate and liquid dispersant.

In addition; Can learn as follows; That is, upwards form when respectively scraping slice row L, make the arrangement phase place inequality of scraping slice 9 that makes progress in week among the slice row L in adjacent one another are scraping all uniformly-spaced to set a plurality of slices 9 of scraping in week; It is made as phase specific energy when identical with the arrangement phase place of scraping slice 9 and strengthens the effect of chopping pre-composition Fp and in the flowing of pre-composition Fp, produce turbulent effect, thereby can improve the mixed of dispersate and liquid dispersant.
