The specific embodiment
The emulsifier unit that the present invention relates to of explanation or an embodiment of fine-grain manufacturing apparatus with reference to the accompanying drawings below.Among Fig. 1, the system of fine-grain manufacturing apparatus 100 is shown with block diagram.Fine-grain manufacturing apparatus 100 has the jar 101 that is used for preserving the raw material A (decentralized photo) of wanting emulsification and is used for preserving the jar 102 of the raw material B (continuous phase) that raw material A is disperseed.The emulsifying device 103 that will describe in detail below mixes these raw material A, B and emulsification.
The pipe arrangement 109 of mixture is provided with circuitous stream 110.On described circuitous stream 110, be provided with size distribution meter 111.Size distribution meter 111 can carry out in-service monitoring to the particle diameter of the decentralized photo the mixture that flows out from emulsifying device 103.In the stream of emulsifying device 103, be provided with the piezoelectric element that can flow path carries out active vibration.Piezoelectric element drives loop 112 by piezoelectric element and drives.
First, second liquid-feeding pump 104,105, piezoelectric element drive loop 112 and are connected with user console 113 with size distribution meter 111.The user of fine-grain manufacturing apparatus 100 uses described console 113 to monitor the size distribution of the mixture that generates at present.And the oscillation intensity of the piezoelectric element that the raw material A liquid that first, second liquid-feeding pump 104,105 is carried and conveying capacity ratio of raw material B liquid, liquor charging amount, emulsifying device 103 are interior is adjusted, and generates needed mixture.Emulsifying device 103 and size distribution meter 111 constitute emulsification portion 114.
Among Fig. 2, represent the emulsifying device 103 that fine-grain manufacturing apparatus 100 shown in Figure 1 has with longitudinal section.The material liquid of carrying from head tank 101,102 by liquid-feeding pump 104,105 flows into emulsifying device 103 interior stream 208a, 208b respectively as 201,202, collaborating in conjunction with stream 208c.And then passing choke block 203,204,205, warp is provided with the expansion section 208f of piezoelectric element 206,207 on wall, and then flows out to device external as 209 through stream 208d.Piezoelectric element 206,207 can make its vibration from external control by thickness slippage vibration mode shown in the dotted line among the figure.
If consider being connected of emulsifying device 103 and pipe arrangement, promptly with as stream 208a, the 208b of the inflow entrance of raw material A, B, is connected as the pipe arrangement of the stream 208d of the flow export of emulsion dispersion liquid, preferably making these flowing path sections is circle.
Between in conjunction with stream 208d and expansion section 208f, three kinds of choke blocks 203～205 are spaced from each other on the flow direction that is configured in liquid stream at interval in turn.First throttle plate 203 is positioned at upstream side, and the hole is formed on central portion, and its aperture efficiency is maximum in three choke blocks 203～205.Second choke block 204 in the middle of being configured in, the central part of the side of upstream side be the taper shape that is recessed into of side downstream, and the downstream is the vertical face of flow direction with emulsification stream 8d.And the aperture efficiency of opening of central portion that is formed on second choke block 204 is minimum in first～the 3rd choke block 203～205.
In addition, flow velocity is decelerated when being provided with the expansion section 208f of piezoelectric element on by wall, thereby can win the time by described position (208f portion).Therefore, the stream portion than other of the area of section of 208f portion setting sometimes is big.
In addition, be preferably in expansion section 208f and produce the generation of the same as far as possible oscillatory shear stress with making the particulate homogenising, thereby even if the cross sectional shape of other stream portion is circular, this circuit portion is preferably formed as the rectangular cross sectional shape for two pieces of plane piezoelectric elements are provided with in opposite directions only.Though the interval of two pieces of piezoelectric elements is in opposite directions also decided by the viscosity of vibration frequency, stoste, make its narrow same oscillatory shear stress that more can produce of trying one's best generally speaking.
There is shown at piezoelectric element 207,208 and be provided with between the stream wall of these piezoelectric elements the situation that is provided with the gap, can hinder the sideslip vibration shown in the dotted line, but, when residual stoste in the described gap portion, when causing the problem of health aspect, described gap portion is sealed also passable with the elastomeric material that retractility is high.
The activity of the fluid-mixing among the expansion section 208f in the emulsifying device shown in Figure 2 103 is described with Fig. 3.Fig. 3 (a) is the figure that flows that is used for illustrating choke block 203～205 parts, and Fig. 3 (b) is the figure that flows that is used for illustrating expansion section 208f part.As mentioned above, the 307 orifice apertures 306 than first throttle plate 203 that are provided with, the orifice aperture of second choke block 204 (オ リ Off イ ス footpath) are little.
Based on this, when the flow of the mixed flow of raw material A, B surpassed the regulation flow, forming eddy current in the stream between first throttle plate 203 and second choke block 204 was that secondary flows 308.By described secondary stream 308 decentralized photo (raw material A) 302 that flows into the raw material between first, second choke block 203,204 from upstream side mixed with continuous phase (raw material B) 301, be dispersed into bigger drop 309.
And then, owing to the little orifice diameter 307 of orifice diameter that has formed at second choke block 204 than the first, the 3rd choke block 203,205, thereby, fierce jet 310 formed towards the downstream of described second choke block 204.And the strong shear stress of following jet 310 to produce splits into fine liquid drops 311 to the drop 309 that generates between first, second choke block 203,204.
The jet 310 that produces towards the downstream of second choke block 204 is along with row broadens gradually toward the downstream.Therefore, can't be under this state by the 3rd wide choke block 205 of aperture efficiency second choke block 204, a part of liquid flows back to and returns and form the secondary stream 312 that side upstream flows backwards.Secondary stream 312 further mixes with fine decentralized photo (raw material A) and continuous phase (raw material B), and the peristome by the 3rd choke block 305 flows to the downstream.
As mentioned above, on the expansion section 208f in the downstream that is formed at 203～205 ones of first～the 3rd choke blocks, disposing piezoelectric element 206,207 in opposite directions.Piezoelectric element 206,207 makes on the stream wall and to produce the vibration of breakking away, thinner the division of the drop of the mixed liquor of raw material A and raw material B.At this, piezoelectric element 206,207 vibrates with mutually opposite phase place shown in Fig. 3 (b).Like this, between two piezoelectric elements 206,207, form the velocity flow profile 315,316 of oscillatory type.Produce shear stresses by described velocity flow profile 315,316, described shear stress becomes the elongated drop 317 that has stretched at flow direction to the spherical droplet-shaped of coming from upstream flow, finally elongated drop 317 is subdivided into a plurality of approximate spherical drops.Thus, produce more fine liquid drops.
The distribution situation of the velocity flow profile of described oscillatory type, the vibration velocity 318 of sideslip direction that can be by piezoelectric element 206,207 is controlled.That is, by the vibration number of drop 319 by time between the piezoelectric element 206,207 and Wall Vibration can determine drop by the time number of times that is torn.Therefore, the speed that flows of required shear stress of the division of corresponding raw material A, B and raw material A, B is adjusted the vibration number and the vibration displacement of Wall Vibration.Thus, can be emulsified into desired particle diameter to raw material A, B.
Usually on piezoelectric element 206,207, apply high voltage.Therefore, the surface that is connected to the piezoelectric element 206,207 of raw material A, B must be insulated.In the present embodiment, omitted though illustrate,, applied insulating properties and resin that retractility is high on the surface of piezoelectric element 206,207.
In the following description, first～the 3rd choke block 203～205 is called passive emulsification portion 313, expansion section 208f is called initiatively emulsification portion 314.In the foregoing description, emulsifying device 103 has passive emulsification portion 313 and emulsification 314 both sides of portion initiatively, 313 carries out rough emulsification by the former, generates meticulous particulate by the latter 314.Therefore, under desired admixture, also can make emulsifying device 103 only have any emulsification portion.
In addition, in order to generate more meticulous particle, also can be provided with passive emulsification portion 313 and active emulsification portion 314 multistage as required.The combination of these emulsification portions 313,314, correspondence will be carried out the rerum natura of interfacial tension between the viscosity, density, raw material A, B of raw material A, the B of emulsification treatment etc. and decide as the admixture of the average grain diameter of the particulate of target, size distribution etc.
In Fig. 3 (b), piezoelectric element 206,207 is set opposite to each other, the two is vibrated with opposite phases with expansion section 208f, but piezoelectric element only be provided with one also passable.Under this occasion, emulsification stream 208d also is preferably at flow direction upper section area roughly the same.A little less than the situation that the strength ratio of the shear stress that produces is provided with two piezoelectric elements 206,207 is in opposite directions wanted, but have such advantage, that is, as long as electric power that the emulsification portion 314 initiatively of can reducing consumes and the driving loop that drives piezoelectric element are one.As long as the part that corresponding shear stress dies down prolongs the time that drop passes through, just can obtain and the identical effect of occasion degree that disposes piezoelectric element in opposite directions, thereby particularly effective in the fewer processing for the treatment of capacity.
Another embodiment of the fine-grain manufacturing apparatus that the present invention relates to illustrates with Fig. 4.In the foregoing description two kinds of raw material A, B are mixed and with its emulsification, and in the present embodiment be the raw material A more than three, B, C ... emulsification generates so-called composite opaque liquid (ダ Block Le エ マ Le シ ヨ Application).Among described Fig. 4,, use three kinds of raw material A, B, C for the ease of understanding.Under the situation of using three kinds of raw material A, B, C, only append an emulsifying device 103b.
Among Fig. 4 (a), the fine-grain manufacturing apparatus 100b that generates composite opaque liquid is shown by block diagram.Among described Fig. 4 (a), omitted user console and with the diagram of the connecting line of user console.The 114b of emulsification portion has two emulsifying devices 103,103b.Generate the mixed liquor 402 of raw material A (decentralized photo) and raw material B (continuous phase) from emulsifying device 103.The emulsifying device 103b that has appended imports raw material C in the mixed liquor of raw material A, B it is disperseed, and finally generates the composite opaque liquid 404 of A/B/C.In order to capture composite opaque liquid, jars 106 downstreams that are arranged on the emulsifying device 103b that has appended.
Show to Fig. 4 (b) pattern the admixture of each raw material A～C among the 114b of emulsification portion in Fig. 4 (a).At upstream side, raw material A is mixed with raw material B, raw material C is mixed among described raw material A of having mixed, the B in the downstream.By repeating said steps in turn, can generate the emulsion of the raw material more than four kinds.At this moment, the diameter of particulate can be by choke block, energising electric power of piezoelectric element etc. is changed.
According to above-mentioned each embodiment, can easily control the particle diameter of emulsion, and, can easily generate the multiple structure of emulsion.Under the situation about producing in batches, the piece of emulsification unit is connected multiple row in parallel carrying out equipmentization from laboratory level.At laboratory level, use one so that a plurality of emulsification unit, generate desired emulsion, and be transformed into when carrying out volume production by equipment, corresponding to treating capacity with the emulsification unit parallel connection.By described step, the problem that can avoid in the prior art scale based on similar law to strengthen.Embodiments of the invention more than have been described, but have the invention is not restricted to the foregoing description.Summary of the invention has partly been put down in writing real spirit of the present invention.
