First dispersal device 1 supplies the mixture 4 of slurry to the gap between rotor 2 and stator 3, to pass through shearing force Dispersed mixture 4.The details is discussed below.

Second dispersal device 60 can be any of dispersal device, for example ball mill, jet mill or high-pressure type are equal Matter device.Because mixture 4 is pre-dispersed by means of the first dispersal device 1, therefore agglomerated particle is dissolved so that mixture 4 is only Include tens microns or smaller of little particle, as discussed below.It is thereby achieved that particle is dispersed into nano level effective It is scattered, and uneven dispersion therefore will not occur.In the event of uneven dispersion, then ball mill will not work, because inciting somebody to action Contain the agglomerated particle bigger than pearl.Jet mill or high-pressure type homogenizer also will not work, because the group bigger than jet size Poly- particle will result in blockage.Therefore, uneven dispersion will occur or device will appear from problem.

Holding vessel 120 has rotary shaft 127, stirring vane 123 and for making stirring vane 123 be rotated around rotary shaft 127 The such as motor of driver element 128 so that preventing from being dispersed into any density unevenness of nano level mixture 4 It is even.The method of stirring mixture 4 is not limited to rotating agitation blades 123, and can be any known method.Due to by mixing The mixture 4 that the coarse dispersion device 110, the first dispersal device 1 and the second dispersal device 60 that thing 4 carries out continuous processing disperse differs Being scheduled on any time point all has constant granule density or constant distribution of particles, therefore can be stored in mixture 4 Deposit in tank 120 and be stirred in holding vessel 120 so that mixture 4 becomes uniform.In addition, it is stored in storage in mixture 4 While in tank 120, the uneven concentration caused by the precipitation of solid particle can be prevented.If however, it can ensure that The concentration and distribution of grain are uniform, then can not provide agitating device to holding vessel 120.It can be provided to holding vessel 120 very Empty pump (not shown), and provide corresponding switch valve (not shown) to pipe arrangement 140,150.Nano level mixture 4 can be borrowed Help vavuum pump and switch valve to defoam.Contact seal part ratio is installed if instead of switch valve in the first dispersal device 1 Such as lip seal prevents surrounding air from entering, then can perform defoaming while dispersed mixture 4.

Shearing-type dispersal device 1 is described referring now to Fig. 3, Fig. 4 and Fig. 5.First dispersal device 1 includes rotor 2 With the stator 3 for being arranged to face to rotor 2.First dispersal device 1 make slurry or liquid mixture 4 by centrifugal force rotor 2 with Flowed between stator 3 towards periphery (towards the direction of periphery) so that slurry or liquid mixture 4 is pre-dispersed.

First dispersal device 1 includes being used to receive by the container 11 of scattered mixture 4 and for by container 11 The cap assemblies 12 of portion opening 11a closings.For example, pass through bolt hole 11c and cap assemblies 12 in the top edge 11b via container 11 Cap assemblies 12 are fixed to appearance by the bolt hole 18c placements bolt 11d in (part 18 for being used to keep stator being discussed below) Device 11, to close upper opening 11a.

Stator 3 is fixed on below cap assemblies 12 (lower surface for being fixed to cap assemblies 12).For example, by via stator 3 In bolt hole 3b and cap assemblies 12 part 18 of stator (be used for keep) in bolt hole 18b placement bolt 3a by stator 3 It is fixed on below cap assemblies 12.Rotor 2 is arranged to face to the lower surface of stator 3.

First dispersal device 1 also includes the rotary shaft 13 for rotating rotor 2 and rotatably keeps rotary shaft 13 Bearing 14.Bearing 14 is fixed to cap assemblies 12 and positioned at the top of stator 3.

First dispersal device 1 includes the (ginseng of distance piece 15 being removeably positioned between rotary shaft 13 and rotor 2 See Fig. 4 c and Fig. 4 e).Distance piece 15 causes by changing in the direction of the first dispersal device 1 --- i.e. the axial direction side of rotary shaft 13 To D1 (referring to Fig. 3 a) --- another distance piece above with different length (thickness) can be adjusted between rotor 2 and stator 3 Gap.That is, reserve with various thickness distance piece 15, with by using one of which come adjust rotor 2 with Gap between stator 3.

When there is provided during distance piece 15, position relative to stator 3 of the rotor 2 in the axial direction on D1 is fixed. That is, it is possible to adjust the gap between rotor 2 and stator 3 using spring or screw.However, when using distance piece 15, Because the axial location of rotor 2 is fixed during operation, therefore the vibration without the concern for defence spring or the pine of screw Dynamic countermeasure.If in addition, using spring or screw, it is difficult in the case of not making rotor 2 inclined accurately movable rotor 2.By contrast, when using distance piece 15, can in the case where not making rotor tilt accurately movable rotor.

By the first dispersal device 1, gap can be accurately adjusted by means of said structure.By the first dispersal device 1, Even if due to unpredictalbe heat thermal expansion occurs for rotary shaft 13, also edge will be moved rotor 2 with the direction that stator 3 separates It is dynamic.Accordingly it is possible to prevent any between rotor 2 and stator 3 contacts.In addition it is also possible to prevent due to unpredictalbe small Gap --- although they are not in contact each other --- and produce overheat.Further, since bearing 14 is located at the top of stator 3, therefore Rotary shaft 13 is located at the top of rotor 2.Because any part of rotary shaft 13 is all not disposed on the lower section (rotary shaft 13 of rotor 2 Set up from rotor 2), therefore can prevent from above drawing because the mixture 4 through processing is attached to rotary shaft 13, bearing 14 etc. The yield risen declines.I.e., it is possible to improve yield.

Cap assemblies 12 there is the part 17 for being used for keeping bearing 14 and be arranged on the lower section of part 17 be used for keep stator Part 18.Part 18 keeps stator 3.Part 17 for keeping bearing, which has, to be used to control the part 18 for being used for keeping stator The part 21 of axial location.Part 21 is abutted by means of the second distance piece 20 with part 18.For example, make part in the following manner 17 is integral with part 18：Via the bolt in part 17 while the second distance piece 20 is clipped between part 17 and part 18 Bolt hole 18e in hole 17e and part 18 disposes bolt 17a (referring to Fig. 4 d).Formed with through hole in the second distance piece 20 20a so that bolt 17a passes through through hole 20a.

Second distance piece 20 is removeably positioned at for keeping the part 17 of bearing to keep stator with being used for Between part 18.Second distance piece 20 passes through by having another distance piece of different length (thickness) to replace on D1 in the axial direction Change and position relative to part 17 of the stator 3 in the axial direction on D1 can be adjusted.That is, reserve has various thickness The second distance piece 20, to adjust position of the stator 3 in the axial direction on D1 by using one of which.

The distance piece 20 of distance piece (also referred to as " the first distance piece ") 15 and second is replaced by using corresponding distance piece, can be with More accurately adjust the gap between rotor 2 and stator 3.That is, by the way that distance piece 15 is replaced with thicker distance piece, The gap becomes big.By the way that the second distance piece 20 is replaced with the second thicker distance piece, the gap diminishes.These combinations replaced More accurate regulation can be realized.For example, reserve with from 0.01mm to 0.50mm using 0.01mm between the thickness of increment The distance piece 20 of spacing body 15 and second.The distance piece 20 of distance piece 15 and second is replaced so that between rotor 2 and stator 3 Gap is tailored to the viscosity and characteristic of mixture 4.

Second distance piece 20 causes position of the stator 3 relative to the part 17 for keeping bearing --- i.e. under stator 3 Surface is relative to for keeping the position of the part 17 of bearing --- by the part 18 for keeping stator relative to for protecting Hold the adjustment of the position of the part 17 of bearing and be adjusted.Therefore, the state regardless of stator 3, can make under stator 3 The position on surface keeps constant.For example, even if when stator 3 is replaced, the position of the lower surface of stator 3 can also be made to keep not Become.Thus, for example by the way that the position of the lower surface of stator 3 is held in a predetermined position into place, can make distance piece 15 thickness and Gap between rotor 2 and stator 3 is identical, so that what structure will be appreciated that for user.That is, will By gap adjustment into desired distance, then thickness and gap identical distance piece 15 must be selected.This improves execution in gap Control under decentralized processing user convenience.

Formed with recess 22 on the upper surface of rotor 2 so that the bottom 13a of rotary shaft 13 is inserted into recess 22 (referring to Fig. 4 c and 4e).Formed with the through hole 22a being opened on recess 22 in rotor 2.The bottom 13a insertions of rotary shaft 13 Into the recess 22 of rotor 2.Bottom 13a is abutted by means of distance piece 15 with recess 22.Fastening is fixed from the downside of rotor 2 Component 23.Fastening member 23 is, for example, bolt.In the bottom 13a of rotary shaft 13, formed with the cloudy spiral shell as fastening part 13b Line, wherein, fastening part 13b is the homologue of fastening member 23.

Fastening member 23 will by the way that hole 22a of the part for fastening member 23 through rotor 2 is fixed into rotary shaft 13 Rotary shaft 13 is fastened to rotor 2 across distance piece 15.Pin 24 is inserted into the recess 22 of rotor 2 and the bottom of rotary shaft 13 In 13a, the rotary power of rotary shaft 13 is transferred to rotor 2.In the recess 22 of rotor 2 and the bottom 13a of rotary shaft 13 In formed with the hole for receiving pin 24.

Circumferentially direction is set pin 24 at uniform intervals, and the rotary power of rotary shaft 13 is transferred into rotor 2. The the second through hole 15b passed through in distance piece 15 formed with the first through hole 15a and supply and marketing 24 that are passed through for fastening member 23.In the reality Apply in mode, used four the second through hole 15b and four pins 24.It is but in a unlimited number in four.

Because rotary shaft 13 and rotor 2 are fastened by fastening member 23 across distance piece 15, therefore rotor 2 is relative to fixed The axial location of son 3 is reliably fixed.Therefore, it is appropriate that can make the gap between rotor 2 and stator 3.That is, Rightly using the distance piece 15 with above-mentioned advantage.

Due to being transferred to rotor 2 using pin 24 come the rotary power for rotating shaft 13 of spinning in the future, therefore with using key and keyway Structure compare, the power in circumferential direction, which distributes, to be improved.That is, rotary shaft 13 and rotor 2 are revolved with balance mode Turn.It is therefore prevented that the disperse power between rotor 2 and stator 3 is different in different opening positions.That is, it can perform Uniform and appropriate decentralized processing.Due to preventing disperse power variant in different opening positions, therefore when gap turn narrow Decentralized processing still can be stable.Further, since the speed of rotation can be increased, therefore appropriate scattered place can be performed Reason.

In plane of the stator 3 towards rotor 2, stator 3 is bigger than rotor 2.That is, vertical with axial direction D1 In plane, stator 3 is shaped as bigger than rotor 2.On stator 3, with towards the surface of rotor 2 (lower surface) opposite surface Formed with the groove 26 for cooling on (upper surface) so that cooling agent flows through the groove 26 for cooling.The quilt of groove 26 for cooling It is positioned to beyond the outward flange of rotor 2.

Due to being formed for the groove 26 of cooling beyond the outward flange of rotor 2, therefore the outward flange of rotor 2 can be cold But.That is, the cooling rotor 2 of groove 26 and the whole region for being used to disperse of stator 3 for cooling can be passed through.Therefore, It can reliably prevent from producing heat in material (just by scattered mixture 4).So as to, it is therefore prevented that the material degradation to be disperseed. In addition, even if material is volatile and inflammable, decentralized processing can also be carried out safely.Traditionally, rotor 2 and stator 3 Be shaped as they towards plane on be of the same size.In this case, outward flange can not be cooled.Due to Higher in heat caused by outer edge, the groove 26 that thus be accordingly used in cooling provides excellent cooling effect.Therefore, can be suitable Appropriate decentralized processing is performed within the temperature range of.

Along radial direction formed with wall 27 on the groove 26 for cooling (referring to Fig. 4 b).Set on groove 26 across wall 27 It is equipped with the port 28 for supplying cooling agent and the port 29 for discharging cooling agent.Supplied from port 28 to the cooling agent of groove 26 Circumferentially direction D2 flows towards the direction D3 that wall 27 is not formed near port 28.Cooling agent is discharged from port 29.For example, Cooling agent can be water.

Due to being constructed such that cooling agent from for supplying the port 28 of cooling agent along single direction for the groove 26 of cooling It flow to the port 29 for discharging cooling agent, i.e. the groove 26 for cooling is terminated so that cooling agent flows along single direction, So that cooling agent is sequentially discharged.In other words, if the groove 26 for cooling is not configured to make cooling agent edge Single direction flows, then a part of cooling agent may be detained so that the cooling agent at the part for the groove of cooling It may not be replaced by new cooling agent, so that cooling capacity deteriorates.By contrast, because the groove 26 for cooling is by structure Cause sequentially to replace cooling agent, therefore cooling capacity is higher all the time.Therefore, it is appropriate to perform at a proper temperature Decentralized processing.

Form the groove for being used to cool down of the first dispersal device 1 and the stator formed with the groove is not limited to said structure thereon. For example, as shown in Figure 5, the stator 76,77 with the groove 71,72 for cooling down can also be used.Fig. 5 a illustrate pass through by Groove improves the example of cooling capacity widening as much as possible in addition to place where screw.Fig. 5 b are illustrated by the bottom of groove Stria is formed in portion to increase with the contact area of cooling agent to improve the example of cooling capacity.Fig. 5 c are shown along in Fig. 5 b Line A6-A6 interception cross section, to illustrate the section of stria or recess 72a.Due in addition to the groove for cooling, stator 76th, 77 have with the identical 26S Proteasome Structure and Function of stator 3, therefore eliminate the explanation of repetition.

As shown in Figure 5, as the groove 26 for cooling, the groove 71,72 for cooling is respectively formed at bigger than rotor 2 Stator 76,77 upper surface, to reach the outside of rotor 2.As wall 27, wall 73,74 be provided to the groove 71 for cooling, 72.The structure similar with the structure of the groove 26 for cooling has similar function.

Next, a pair structure different from the structure of the groove 26 for cooling down is described.Groove 71 for cooling extends To the outward flange of stator 76.In the part formed with bolt hole 3b, formed with protuberance 71a.Because groove 71 is towards outward flange Extension, therefore cooling effect strengthens.In the bottom of the groove 72 for cooling, circumferentially direction is formed with recess 72a.Thus, it is cold But the heat exchange amount increase between agent and stator 76, so as to enhance cooling effect.The cooling effect of groove 71,72 is colder than groove 26 But effect is high.As described above, when using the stator with the groove 71, any one of 72 for cooling down rather than with for cold During the stator of groove 26 but, high cooling effect can be obtained so that appropriate disperse is performed within the scope of appropriate temperature Processing.

Formed with the hole 31 for inserting rotary shaft passed through for rotary shaft 13 in stator 3.Mixture 4 is from the hole of stator 3 The outside of 31 position is supplied to the gap between stator 3 and rotor 2.

Specifically, in stator 3 in the outside in the hole 31 for inserting rotary shaft formed with for supplying mixture 4 Through hole 32.In other words, through hole 32 is oriented to be separated by a certain distance with hole 31.Set in the part 18 for keeping stator There are a port 33 and passage 34, port 33 is used to supplying mixture, and passage 34 is by through hole 32 and the port 33 for supplying mixture Connect and passage 34 is arranged in stator 3.The mixture 4 supplied from port 33 passes through the passage 34 and stator 3 in part 18 In through hole 32 be directed to gap between stator 3 and rotor 2.One end set of the port 33 for supplying mixture has For the flange of connection, to be connected with pipe arrangement 130.

By such configuration, when making the rotation of rotor 2 while mixture 4 are being supplied, can to have supplied to logical The mixture 4 in hole 32 is outwards flowed by means of centrifugal force.Therefore, reached without mixture 4 near pivot.Therefore, with In the hole 31 of insertion rotary shaft (also referred to as the first hole of rotary shaft " be used for insert ") or the second hole 36 for inserting rotary shaft In do not need containment member such as mechanical sealing member, wherein, the second hole 36 will be discussed below.That is, through hole 32 be positioned in For inserting the hole 31 of rotary shaft at a distance so that no mixture 4 flows to hole 31.Therefore, dispersal device Structure can simplify.Furthermore, it is not necessary that carry out the replacing caused by containment member deteriorates to containment member.

Port 33 and passage 34 for supplying mixture tilt with their step-downs along direction D4 towards radial center. However, can tangentially D5, D6 inclination for example with their step-downs for the port 33 and passage 34 for supplying mixture. Passage 34 and it is formed so that the bottom of passage 34 is located at the position that is connected with through hole 32 for supplying the port 33 of mixture Place.Therefore, through hole 32 can be located near hole 31.

In the part 18 for keeping stator the of rotary shaft is inserted formed with being used for of being inserted through for rotary shaft 13 Two holes 36.Second hole 36 is provided with the labyrinth seal structure 37 as non-contacting sealing structure.Here, labyrinth sealing knot Structure has following configurations：The configuration passes through in fixed sidepiece (being used for the part 18 for keeping stator) and rotary shaft (rotary shaft 13) A sidepiece or two sidepieces on form one or more recesses and/or convex portion and have between rotary shaft and fixed component The concavo-convex gap of series connection.Such configuration plays seal.The size of recess and convex portion is, for example, 0.01mm to 3.00mm.

From for keep the outside of the part 18 of stator in part 18 and with the second hole for inserting rotary shaft The space 38 of 36 top connection supplies air.By being externally supplied air from part 18, there is provided air purging sealing knot Structure 39.For example, air purging sealing structure 39 has space 38, the passage 39b for purging and the part for supplying air 39a, wherein, space 38 is by for keeping the part 17 of bearing and for keeping the part 18 of stator to be formed, for the logical of purging 39b formation in road is in part 17 and externally connected by space 38, and the part 39a for supplying air is arranged on passage 39b Outside portion sentence supply for purge air.Air purging sealing structure 39 passes through passage 39b and sky as indicated by arrows f1 Between 38 the air supplied from part 39a is supplied to the gap between the second hole 36 and rotary shaft 31.The air provides sealing work( Energy.

It is used to determine to receive formed with recess 18f in the outside in the second hole 36 in the part 18 for keeping stator Son 3 is fixed to the bolt 3a of part 18.Due to formed with recess 18f, therefore form the second hole 36 for inserting rotary shaft Inner peripheral portion 18g is shaped as such as protuberance.Rotary shaft 13 has the protuberance outside the inner peripheral portion 18g for protruding from part 18 13g.As indicated by arrows f1, by the gap between inner peripheral portion 18g and protuberance 13g and supplied from the air of part 39a supplies To the gap for being extremely used to insert between the second hole 36 of rotary shaft and rotary shaft 31.

Labyrinth seal structure 37 enhances the sealing effectiveness to the second hole 36 for inserting rotary shaft.Air purging is close Seal structure 39 by means of clean enhance to for insert rotary shaft hole 31 and for insert rotary shaft the second hole 36 it is close Seal effect.In the first dispersal device 1 as described above, because mixture 4 is directed to so that what centrifugal force was utilized effectively Position, therefore be not required to provide labyrinth seal structure and blowing mechanism.However, it is possible to provide labyrinth seal structure and blowing One of mechanism is swept to strengthen sealing effectiveness.Both labyrinth seal structure and blowing mechanism can be provided to further enhance Sealing effectiveness.

Container 11 has tapered wall 42, cylindrical wall 43 and the port 44 for discharge, wherein, tapered wall 42 has from top The cross section to diminish to bottom, cylindrical wall 43 are located in tapered wall 42, and the port 44 for discharge is in the bottom of tapered wall 42 Place.Port 44 for discharge is arranged on the lower end of container 11, will be discharged by scattered mixture 4.In port 44 End be provided with flange for connection so that pipe arrangement 140 is connected to the flange.Because the mixture 4 after scattered passes through Tapered wall 42 is discharged, therefore the amount for being attached to the mixture 4 not being discharged of inwall greatly reduces.This improves yield And perform appropriate processing.Vavuum pump can be provided to container 11, to prevent air to be mixed into mixture 4.

Container 11 is provided with the cooling body 41 with refrigerating function.For example, cooling body 41 includes being collectively forming container The wall 42 and wall 43 of 11 outer surface.Cooling body 41 also has for forming the space of cover outer surface (wall 42 and wall 43) Component 45, the component are located at the outside of the two walls.Cooling body 41 also has the port 46 for being used for supplying cooling medium and used In the port 47 of discharge cooling medium.For example, can be commonly referred to as the component of shield for forming the component 45 in space, and And space 48 is formed between component 45 and wall 42 and 43 so that cooling medium such as cooling water is filled in space 48.

For example, it is arranged on for supplying the port 46 of cooling medium on the following side of the component 45 for forming space to incite somebody to action Cooling water supply is to space 48.For example, it is arranged on component 45 for forming space for discharging the port 47 of cooling medium So that cooling water to be discharged from space 48 on upper lateral part.

By configuration above, cooling body 41 has by wall 42,43 come the function of the inside of cooling container 11.Cooling Mechanism 41 is also cooled down by scattered mixture 4.If mixture 4 contains volatile material, the material to gasify it is cooled and Return to liquid form.The structure of cooling body 41 is not limited to said structure, and can be any of structure.

The container for forming the first dispersal device 1 is not limited to container 11, and can also be such as the container 81,86 in Fig. 6.First Container 81 in such as Fig. 6 a is described.In addition to container 81 has agitator 82, container 81 has identical with container 11 26S Proteasome Structure and Function.Therefore, the explanation of repetition is eliminated.

Such as port 44 of the container 81 in Fig. 6 a with wall 42,43 and for discharge.Container 81 is equipped with cooling body 41. Container 81 is further equipped with agitator 82.Agitator 82 wipes the slurry mixture 4 for the inner surface for being attached to wall 42,43 off.Wipe off Mixture 4 is discharged with unattached mixture 4 together with the port 44 for discharge.Agitator 82 have agitating plate 82a and Motor 82b, wherein, agitating plate 82a is shaped as the shape for complying with wall 42,43, and motor 82b rotates plate 82a.Agitator 82 is also With rotary shaft 82c and bearing 82d.Agitating plate 82a is so shaped that the space between agitating plate 82a and wall 42,43 is about 0 To 20mm.Agitating plate 82a is made of metal or is made up of metal and resin.Here, agitating plate 82a has two mixing parts 82e, scraped with two opening positions circumferentially.However, it is possible to by being combined to make agitating plate 82a that there are three to plate Or more mixing part, or, agitating plate 82a only can also have a mixing part.In the example shown in Fig. 6 a, Due to needing to set rotary shaft 82c, the port 44 that thus be accordingly used in discharge is connected to connecting tube 83, to be connected to by connecting tube 83 Pipe arrangement 140.Because the mixture 4 after scattered is discharged by tapered wall 42, therefore it is attached to the mixing not being discharged of inwall The amount of thing 4 greatly reduces.In addition, agitating plate 82a promotes the discharge of mixture 4.Therefore, output increased.

Next, the container 86 to another example as the container for forming the first dispersal device 1 as shown in Fig. 6 b It is described.Container 86 is also used as the tank for storing the mixture 4 after disperseing.That is, container 86 has cylindrical wall 86a and is located at Spherical bottom 86b below cylindrical wall 86a.For being arranged on together with the port 86c and switch valve 86d of discharge under the 86b of bottom End.

Container 86 as shown in Fig. 6 b is discussed with being matched in single is scattered by fully decentralized mixture 4 as following State.For example, container 86 for disperseing a small amount of needs with being properly dispersed and the processing of expensive mixture 4 matching.Dividing After dissipating processing, bolt 11d is removed so that container 86 to be pulled down from cap assemblies 12 or from the rotor 2 and stator for being attached to cap assemblies 12 3 pull down.Container 86 can be directly used as the container for transport and be transported to desired position.Therefore, it is attached to first point The mixture 4 in bulk for putting 1 outer surface in a further arrangement can be recovered, so as to improve yield.It is also used as being used to store The shape of the container 86 of the tank of mixture after processing is not limited to above-mentioned shape, and it can also be taper.As an alternative, container 86 Can be for receiving largely by scattered mixture or the large tank for being for example divided into two parts.It is also used as being used for The container of the tank of mixture after storage processing can be equipped with cooling body 41.

For example, as specified in Japanese Industrial Standards (JIS) stainless steel such as SUS304, SUS316, SUS316L or SUS430 or carbon steel such as S45C or S55C as specified in JIS may be used as forming the He of rotor 2 of the first dispersal device 1 The raw material of stator 3.Ceramic such as aluminum oxide, silicon nitride, zirconium oxide, Sai Long, carbonization as specified in JIS can also be used Silicon or tool steel such as SKD, SKF.Thermal spraying thereon (such as oxidation aluminium thermal spraying or zirconia thermal spray) can also be used There is the metal of ceramics, such as thermal jet scribbles the stainless steel of ceramics thereon.By using the metal system that ceramics are scribbled by thermal jet thereon Into rotor and stator, the life-span can be extended, and any metallic pollution can be prevented.

By using the pre-dispersed processing of the first dispersal device 1, mixture 4 is fed into the rotor 2 of the first dispersal device 1 Between stator 3, so that mixture 4 is flowed by centrifugal force towards periphery, so that mixture 4 is disperseed.Pass through first Dispersal device 1 and pre-dispersed processing, yield is high, and dispersibility is high, and decentralized processing performs within the scope of appropriate temperature. That is perform appropriate pre-dispersed processing.By the first dispersal device 1 and pre-dispersed processing, due to can locate scattered Container 11 and cap assemblies 12 are separated to be cleaned after reason, therefore it is easy to clean.

As described above, by the first dispersal device 1, can adjust by means of shearing force to realize scattered rotor 2 with determining Son 3 between gap and can be securely fixed the gap between rotor 2 and stator 3.In addition, rotor 2 is with the side of balance Formula rotates so that is uniformly dispersed mixture.Therefore, by the mixed of the bulky grain containing hundreds to thousands micron of coarse dispersion The pre-dispersed of compound 4 can be performed reliably.

In the first dispersal device 1, the gap between rotor 2 and stator 3 is preferably larger or equal than 10 microns and is less than Or equal to 1000 microns.If the gap between rotor 2 and stator 3 is less than 10 microns, rotor 2 and the meeting of stator 3 are close each other, Thus rotor 2 and stator 3 are in contact with each other and the thermal expansion caused by the heating during decentralized processing and impaired wind Danger increase.If the gap between rotor 2 and stator 3 is more than 1000 microns, dispersion solid particle can become difficult.Work as rotor When gap between 2 and stator 3 is more than or equal to 10 microns and is less than or equal to 1000 microns, it can be effectively carried out solid Particle is dispersed into certain finest level, such as average diameter is less than tens microns, preferably less than 10 microns.

Incidentally, the dispersal device of shearing-type the 3rd can be set between the dispersal device 1 of coarse dispersion device 110 and first (not shown).In this case, for example, the 3rd dispersal device can have between 1000 microns between rotor and stator Gap so that the solid particle in mixture 4 is dispersed into less than 100 microns.First dispersal device 1 can be in rotor 2 and stator 3 Between there is 100 microns of gap so that the solid particle in mixture 4 is dispersed into less than 10 microns, and mixture 4 is supplied To the second dispersal device 60.Therefore, even if the mixture supplied from coarse dispersion device 110 contains bulky grain, mixture it is pre- It is scattered to perform reliably in a short time.

Because the first dispersal device 1 is by shearing force dispersed mixture 4, therefore can realize dispersed.That is, due to making Mixture 4 flows between rotor 2 and stator 3, therefore shearing force is applied to entire mixture 4.Therefore, apply to mixture Localized variation (so-called " short path ") is not present in 4 shearing force so that dispersion efficiency uprises.

It can be used for as the first dispersal device discussion such as shearing-type dispersal device 1 in Fig. 3 to Fig. 6 according to mixture 4 and particle is dispersed into nanoscale as the second dispersal device 60.That is, rotor 2 in shearing-type dispersal device 1 and stator 3 it Between gap setting into being closer to, for particle is dispersed into nanoscale.Following decentralized system can be effectively carried out pre- Disperse and the particle in mixture can be dispersed into nanoscale：The decentralized system includes cutting as the first dispersal device Gap between cut type dispersal device 1 and rotor 2 and stator 3 is less than the conduct in the gap between the former rotor 2 and stator 3 The shearing-type dispersal device 1 of second dispersal device.

Next, some modifications of reference picture 7 and Fig. 8 to decentralized system 100 are described.Fig. 7 is suitable for using more The schematic diagram of the decentralized system 102 of the decentralized processing in individual path.In addition to decentralized system 102 has multiple paths, disperse system System 102 has the identical configuration of system 100 and identical function with being discussed above.

As shown in Figure 7, decentralized system 102 includes coarse dispersion device 110, pans 112, the first dispersal device 1, second Dispersal device 60 and holding vessel 120.The downstream part of pump 142 in pipe arrangement 140 is connected to pans 112 simultaneously by pipe arrangement 134 It is connected to coarse dispersion device 110.Pans 112 are connected to the upstream portion of the pump 132 in pipe arrangement 130 by pipe arrangement 136.By It is stored in the first dispersal device 1 by pre-dispersed mixture 4 in pans 112.Then it is back to by pre-dispersed mixture 4 First dispersal device 1 is pre-dispersed to repeat.In addition, it can be returned by pre-dispersed mixture 4 by means of the first dispersal device 1 To coarse dispersion device 110.That is, it is pre-dispersed to be repeated by decentralized system 102, cause bulky grain to promote pre-dispersed It is dispersed into the solid particle that average diameter is, for example, 10 microns or smaller.

As shown in Figure 8, as decentralized system 100, it is scattered that decentralized system 104 also includes coarse dispersion device 110, first Device 1, the second dispersal device 60 and holding vessel 120.However, pump is not provided to pipe arrangement 130.Compressor 160 passes through flow control Valve 162 and filter 164 processed are connected to coarse dispersion device 110.That is, to connection coarse dispersion device 110 and compressor 160 Pipe arrangement 166 provide flow control valve 162 and filter 164.Flow control valve 162 adjusts from compressor 160 and leads to rough segmentation The flow of the compressed air in bulk for putting 110.Filter 164 removes unwanted material from compressed air.

By decentralized system 104, dusty material and fluent material are in the case of pressurized by coarse dispersion.Then, slightly Mixture 4 in dispersal device 110 is pressurized by means of compressor 160 and flow control valve 162.Therefore, mixture 4 by means of Pressure from coarse dispersion device 110 is directed to the first dispersal device 1 by pipe arrangement 130.

Next, such as decentralized system 106 in Fig. 9 of another example as decentralized system is described.Disperse system System 106 is characterised by that it includes coarse dispersion device 170, and the coarse dispersion device 170 floats in dusty material because being hydrophobic On liquid surface or caking (the relatively agglomerate being made up of the powder of absorption liquid) when in mixed-powder material and fluent material side Face is excellent.In addition to decentralized system 106 includes coarse dispersion device 170 rather than coarse dispersion device 110, decentralized system 106 have and the identical configuration of decentralized system 100 and identical function in Fig. 1.Eliminate the explanation of repetition.

Coarse dispersion device 170, which has, is used for the part 111 for supplying fluent material and the part for supplying dusty material 112.Coarse dispersion device 170 also has stirring vane 173, is connected to the rotary shaft 177 of stirring vane 173 and makes rotary shaft The such as motor of driver element 178 of 177 rotations.Rotary shaft 177 is from the eccentric (rotary shaft 177 in the center of coarse dispersion device 170 It is oriented to off-center) so that deflection is produced by the rotation of stirring vane 173 and is vortexed.Coarse dispersion device 170 for example with Tubular sidepiece and curved bottom.However, coarse dispersion device 170 is not limited to this shape.

Dusty material P is supplied to by means of deflection caused by stirring vane 173 by the part 112 for supplying dusty material In vortex.Part 112 for supplying dusty material for example can be metering type oscillating feeder.But for supplying powder material The part 112 of material is not limited to this type, and can also be another type of oscillating feeder or auger type feeder.Supply Dusty material in being vortexed to deflection is prevented from luming.Therefore, the dusty material during deflection is vortexed is supplied to by means of coarse dispersion Device 170 is by scattered without luming.Further, since stirring vane 173 rotates in off-centered opening position, therefore can be true Guarantee in from for supply fluent material part 111 and for supply dusty material part 112 supply raw material it is broad Space.Furthermore, it is possible to improve the accuracy of the ratio of the material for mixture 4.

It is as described above, pre-dispersed by the first dispersal device 1 by decentralized system 100,102,104 and 106, mixture 4. Nanoscale is dispersed into by the second dispersal device 60 by pre-dispersed mixture 4.Therefore, solid particle is efficiently made more tiny And reach nanoscale.
