CENTRIFUGAL SEPABATING MACHINE.
Application filed. January 7, 1927, Serial No. 159,614, and in Sweden September 10, 1925.
In the wellknown type of drums for cenmixture to be separated. This is illustratedv by Figures 1 and 1? of theaccompanymg drawings each figure showing one half of two ad acent plates a and a, in sectional elevation. At the left hand'sid e in Figure 1,
the inlet holes b for the liquid to be separated, are situated at a relatively short distance from the inner edges of the plates and in Figure 1 at the, right hand side the inlet holes 0 are nearerto the outer edges of the plates, the arrows in each figure indicating the main direction of the currents which occur when two liquids of different specific gravities are being separated. The specific gravity of the, liquid radially outwards of the holes should obviously be higher, and
that of the liquid radially inwards ofthe holes should be lower than that of the orig inal (incoming) mixture; It a complete separation takes place, the liquid discharged from the outer edge should consist of heavy components only and the discharge from the inner edge should be free from such com-- ponents. v
If the liquid mixture to be separated contains a high percentage of heavy components or if it is most important thatthe separated heavy components should be as free as possible from lighter ones, the unseparated mixture must be introduced between the plates near to their inner edges, 1'. e. the drum should be of a construction such as is shown in Figure 1, because the distance the greater proportion of the mixture (the heavy components) must be caused to traverse by centrifugal force is much longer than that which much be traversed by the smaller proportion thereof. A typical example of this is the separation of cream and milk, where as a rule about 90% heavy components (skim milk) are separated, which should contain the smallest possible amount of light ingredients (fat).
In converse cases, for instance, the separation of oil and water where the'proportion of water usually does not exceed 10% and where it is more important to obtain water-free oil than oil-free water, the inlet holesshould be situatedmearer to the outer edges of the plates as shown in Figure 1. 1n some instances, however, a combination oi these arrangements must be used, for instance, for a mixture of 10% oil and 90% water, especially ii'both waterdree oil and o l-tree water are requlred. Themixture should first 'be run through a drum con-- structed 'as'shown in Figure 1 in which drum the separated Water becomes practically tree from oil and it can therefore be discharged anywhere or be used again, but the separated oil will contain a slight percentage oi water, which latter mixture must then be treated in a drum-constructed as shown in Figurel. I up rom the above, it will'beunde'rstood that it is necessary for different purposes to use centrifugal drums differing in this respect in order to obtain the best separating results The present invention has for its object an arrangement which a centrifugal drum" can be ad usted in a simple manner so that.
the positionof the inlet for the liquid into the conical plates will be always the most tween the conical plates to suit the different purposes for which the drum is used, 7
The invention is illustrated by Figures 2 to 6 of the accompanying drawing, in which different arrangements are shown, Figures 2 and 3 show the lower parts of two centrifugal drums in sectional elevation, Figure 4 is a plan view of the conical intermediate plates shown in Figures 2 and 3 respectively and Figures 5 and 6 are plan views of the arrangements shown in Figures 2 and 3 respectively, but with only the bottom plate in place (all other intermediate plates being removed).
In Figures 2 to 6, 1' is the shell of the drum,'2 a receiver and distributor for the supply of liquid between which distributor and the bottom of the shell 1 are channels 3 for conveying the incoming (feed) liquid lOl') from the centre of the drum to holes or openings 4 in said distributor through which holes the liquid is led in between conical in termediate plates 5 formed with holes 6 corresponding with the holes 4 in the distributor 2. The holes 6 form vertical channels through which the feed liquid is led and whence it is distributed between the conical intermediate plates 5. 7 is a bottom plate with holes or openings 8. p
In Figures 2, '3 and 4 are shown plates 5 provided with radially elongated openings 6 and the distributor 2 shownin Figures 2, 3, 5 and 6 has corresponding openings. In Figures 2 and Q the bottom plate 7 is formed with series of holes 8 'angularly displaced and with their centres situated on a spiral or the like at different distances from the drum centre'in such a way that all the holes at the same radial distance correspond with portions of the elongated holes in the plates 5 and in the distributor'2. This bottom plate 7 can be placed in different angular positions relatively to the dis r tributor 2 so that any hole of each series registerswith' a portion of an opening in the distributor 2 and plates 5, thus enabling Figures 3 and 6, but in the latter event the holes in the bottom plates 7 must then be arranged as in the intermediate plates 5 in the positions of the inlet to the plates 5 to;
be varied according to the different angular positions of the bottom plate 7.
In Figures 3 and 6 is shown a bottom plate 7 formed with spirally elongated openings 8 corresponding in number with the radially elongated openings in the distributor 2 and the plates 5Q This bottom plate 7 can be turned on the distributor 2 and the positions of the inlets from the distributor 2 to the intermediate plates 5 can, consequently, be
varied according to the different angular positions of the bottom plate 7. g 7
Although only the above arrangements are shown in the drawings it is obvious that other modifications can be made within the scope of the invention. Thus, the holes in the intermediate plates 5' and in the distr1butor2 can be arranged in se'ries on sev eral radial lines instead of being elongated or they can be made like the holes 8 in the bottom plate 7 in Figures 2 'and 5 andIin ing apertures in the conical parts thereof,
adapted for theintroduction and distribution between said plates of anincoming supply of liquid, a distributor formed with openings constituting an inlet to the spaces between said conical plates: adapted to receive and distributethe incoming liquid to' said apertures, and a bottom plate provided wlth apertures for cooperation with the openings in said distributor to vary the position of said inlet according to the required liquid separation upon rotation of the bottom plate.
'2. A centrifugal drum as claimed in claim 1, in which the intermediate plates and the distributor are formed with groups of apertures radially in line, said drum being provided with a bottom plate having a series of apertures situated at different distances from the "drum center and adapted to be placed in different angular positions, whereby apertures at the same radial dis tance from" the drum center will register with the apertures in the intermediate plates and the distributor and the positions of the inlets from the distributor to the spaces between the intermediate p'lates'ca'n be varied by placing the bottom plate in difl'erent angular positions.
