APPARATUS FOR EMULSIFICATION OF IMMISCIBLE INGREDIENTS a Ib / Ye/v-ra/ M BeH ZiXe/V Fig.6-
Patented Dec. 6, 1932 UNITED STATES PATENT OFFICE NIELS BENDIXEN, OF LONDON, ENGLAND, ASSIGNOR TO J. C. VREDENIBURG, OF LONDON, ENGLAND APPARATUS FOR EMULSIFICATION OF IMMISCIBLE INGREDIENTS Application filed April 16, 1931, Serial No. 530,687, and in England November 24, 1930.
This invention relates to an apparatus for emulsification of immiscible ingredients.
In the known emulsors a pressure is created on the liquids in a closed container by centrifugal force and by releasing this pressure through spray-nozzles, knife-edges, etc., an atomizing effect is obtained by what is described as an explosion occurring the moment when the liquids are slung or pressed out of the container. This type of emulsors has the drawback, that the container must be made very strong to guard against bursting, and even the greatest precautions will often not suffice in case of stoppage of the fine outlet aperture.
The present invention is based on a principle different from the pressure-emulsors. The new apparatus employs no closed container but consists of two horizontally rotating metal discs which are detachably connected, for instance screwed together, in such a way that they hold in position between them a series of perforated metal jackets or rings of different diameters, the said perforations being covered by metal. Means are provided for feeding the liquids to be emulsified inside the smallest ring or jacket. By the centrifugal force the liquids are slung out through the smallest ring and atomized. The mist is then caught by the second ring and in this state it is possible to carry the atomiz-ing very far, and this minimizing of the atomized particles can be carried further and further by adjusting the number of jackets or rings according to the fineness desired.
In a preferred embodiment of the invention the jackets are in the form of circular rings placed concentric to each other and to the center of rotation. Carriers, as for instance baflies or vanes, may be provided for. moving the mixture through the perforations. The same results may be obtained by giving the rings certain shapes, as square, rectangular, and making their sides corrugated, serrated, etc. The jackets or rings may also be placed excentri to each other.
In the drawing forming part of this specification some preferred embodiments of the 50 invention are illustrated.
Fig. 1 is a sectional elevation showing an apparatus with a plurality of rings interposed between the two discs;
, Fig. 2 is a top View thereof, the upper disc of the apparatus being removed;
The Figs. 3-0 show different shapes and arrangements of the rings or jackets held in position between the said discs.
Referring first to Figs. 1 and 2, a and b are two cylindrical metal discs which can be screwed together by means of a screw-threaded metal part c or otherwise. They are meant to revolve at great velocity, for in-' stance 10,000 revolutions per minute, around their centres. The upper disc is provided with a feeding funnel cl, meant to receive during the revolution the mixture to be emub sified. By means of holes a the funnel communicates with the space between the two discs. holes 6 perforated metal rings f f P, are placed concentric to each other and to the center of rotation in annular grooves 9 y rovided in the upper face of the disc I).
he perforations h h h are covered with metal gauzes i i 2' The rings are held in position when the discs at and b are screwed together, and in such a way, that no part of the mixture can pass between the rings and the discs and the only outlet will be through the perforations.
The working of the machine is as follows:
The discs are revolved, and when the desired velocity is obtained, the mixtureof the immiscible ingredients is fed into the funnel in liquid form. They will then by passing through the first ring f be transformed into a mist. If the atomizing obtained is sufficiently fine for the purpose, the process is at an end, and the mist is collected in a container 7'. within which the apparatus rotates. But if the atomizing is insufficient, one or more rings 7, f are added, and the mist slung out through the first ring will be slung out through the perforations and metal gauzes of the battery of two, three, four or more rings, each time passing through a. ring of greater peripherical velocity than the previous, and therefore the atoniizing effect is gradually and proportionally increased as the Between these discs and outside the worthy pressure inside the apparatus and thus avoid any danger from bursting. There will be no danger of bursting of the apparatus, because the outlet from the rings can be made many times greater than the feedingopening, as no special proportion between the two is necessary for obtaining emulsions.
In some cases, especially when the liquids to be emulsified are of low specific gravity, and therefore will not be so responsive to the centrifugal force created in the apparatus as heavier liquids, it is preferable to applv some kind of carriers, as for instance bafiles or vanes 70 k, 70 before the first ring and even between the following rings. These bafiies may be either independent of the rings or formpart of them They will give to the fluids that centrifugal force which in certain cases will be necessary for a vigorous passing of the fluids through the perforations of the rings.
In the modification illustrated in Fig. 3 the rings are placed excentric to each other and this last position will then in cases make the bafiles unnecessary, because the so arranged rings act as carriers of the fluids in the same way as vanes, and the necessary centrifugal force will be applied to the fluids.
The same force can be obtained without placing the rings or jackets in excentric pos1- tion to each other, namely by giving the rings or jackets certain shapes as square, rectangular (Fig. 4) oval (Fig. 5) etc., and (or) making their sides corrugated (Fig. 6) serrated, etc., and they can also in this case be placed excentrlc to each other.
