Definitions

• the invention relates to a method as an apparatus for continuous homogenising or emulsification of liquid, where the liquid in a ultrasound chamber with lamellas or guiding plates, especially placed on the outer walls of the chamber, but also possibly with a place in the area up to this, can be submitted to a cinematic- mechanical treatment, as an example by stirring , and with an continuous stream, which subsequently is guided over the surface of several ultrasound generators.
• this can be obtained respectively by a driving form for ultra sound transducers, and by the establish dynamic-physical state of the lamellas, and characteristic of, that a majority of transducers are driven in displaced succession, while at least in change one transducer is in rest, as that the lamellas during work can be given a rotating movement.
• the ultrasound head can cool down, before its critical temperature for destruction has been reached.
• Another advantage is also that the ultrasound head and its electrical resistence is lowering by cooling, why there further also here has been obtained an advantage.
• one now can couple as drive the ultrasound heads more stabile, inside a lesser range of temperature.
• a further advantage is also that one, by continuous shift between the heads, further can obtain a higher degree of efficiency of the arrangement. As a shift and stop will change the condition of cavitation, so that the cavitation or emulsification can be more effective or maintain optimum driving in the liquid.
• FigJ shows in perspective a ultrasound chamber for homogenisation as emulsification of liquid, with guiding plates and driving or working of the ultrasound transducers in displaced order ,-
• Fig.2 shows a ring of lamella- or guiding plates, which rotate together or jointly around or in the centre axle of the ultrasound chamber
• Fig.3 shows in perspective and seen from the side a single vertical lamella-or guiding plate, which rotate around itself, -
• Fig.3B shows a single rotating lamella-or guiding plate as Fig.3, but seen from upper, and
• Fig.4 shows a picture of pulsing guiding ultrasound signals.
• FIGJ Shows in perspective a ultrasound chamber 1 for homogenisation as emulsification of liquid(s) I as II, with guiding plates 2 and working or driven of ultrasound transducers 4 which self each and together work in displaced order.
• the figure shows an example of an embodiment with vertical placed chamber 1 or boiler 1, which self also in the same time make a pressure safe chamber of mixing 1.
• the liquids I as II which in the example of embodiment have been supplied from above in the chamber of mixing 1, will immediately after this be influenced of an arrangement of wheel of scoop 3. Where the just now partly mixed liquid I as II via the wheels of scoops 3 will be thrown against the guiding plates 2, and in the same time, because of the liquids I as II continuous have been supplied from above via supply lines,- then will the partly homogenised liquid be led against the bottom of the chamber 1 to the exhauster pipe 8, and to continued treatment via the ultrasound transducers 4.
• the ultrasound arrangement 4 can as shown on the figure ideal as an example consist of four ultrasound transducers 4. Which as an example could work in the field from 18-120 kHz, but still as here ideal as an example in the field from 20 -50 kHz.
• An ideal cycle of mutual working operation for the transducers 4 will be by a continuous mutual changing 5 as "rif 5 between these. So that some of the transducers 4 drive, and other transducers 4 do not drive.
• one drive or work with three transducers 4 at a time and so successive working or driving of the common system of the transducers 4.
• driving three transducers 4 at a time Where for that matter the one transducer 4 continuous in its "rif 5 or changing will be new.
• Fig.2 shows a ring of lamellas -or guiding plates 2, which rotate 9 together or joint around/in the centre axle of the ultrasound chamber 1.
• the system 2 could consist of as an alternative several rotating 9 ring systems or rims 9' with vertical sitting plates of lamellas-or guiding plates 2. Where these 2 or the rims 9' then perhaps alternative ideal could drive or work opposite each other 2, as 9', or perhaps with different speed or both working operations in combination.
• Fig.3 shows in perspective and seen from the side a single vertical lamella-or guiding plate 2, which rotate around itself.
• the arrangement 2 could of cause also be combined with the system, which is shown in Fig.2.
• the system will especially has an extra effect, if the system turn opposite of, what the arrangement of middle rings system 3 do.
• Fig.4 shows a picture of a pulsing 7 ultrasound signal 10, which drive or work as a whole. And which drive as a part of the "rif- driving of the ultrasound transducers 4, namely in a displace succession 5, with one transducer 4 in rest, by which there, by this summing up driving, has been obtained a specially effect namely a "synergi" -effect, in the effectiveness of the total effect of homogenising. And which effect therefore is larger than one logical could think, with or by every one of the single section-operations or working forms 5 as 7, "looked” driven for itself and without the other working form as supplement .
