C23 My CARL GUSTAF PATRIK DE LAVAL, OF STOCKHOLM, SVEDEN, ASSIGNOR TO THE AKTIEBOLAGET SEPARATOR, OF SAME PLACE.

CENTRIFUGAL SEPARATOR.

SPECIFICATION forming part of Letters PatentNo. 463,794, dated November 24, 1891.

Application filed April 3, 1891. Serial ITO-387,506. (N model.)

To all whom it may concern:

Be it known that I, CARL GUSTAF PATRIK DE LAVAL, a subject of the King of Sweden, and a resident of Stockholm, Sweden, have invented new and useful Improvements in Centrifugal Separators, of which the following is a specification.

This invention relates to that class of centrifugal separators which are provided with imperforate bowls or drums and which are employed for separating compound liquids into liquids of different specific gravities'for instance, for separating milk into cream and skim-milk.

This invention has particular reference to a separator of this class in which the bowl is provided with numerous rings or conical plates, whereby the liquid in the bowl is divided into numerous thin layers, arranged across the radial lines of the bowl. A sepa rator of this kind is described and shown in Letters Patent No. 432,719, dated July 22, 1890. In the operation of the separator each thin layer of liquid is separated into two liquids of different densities, forming two currents, whichfiow in opposite directions, the specifically heavier liquid flowing along the under side of the ring or {plate above the layer toward the circumference of the bowl and the specifically lighter current along the upper side of the ring or plate below the layer toward the axis of the bowl.

The object of this invention is to prevent these currents from meeting and interfering with each other, whereby their movement would be retarded and a new emulsion or mixture would be formed. This object is attained by providing the rings or plates with corrugations or channels which receive the separated liquid and prevent it from (30111 mingling with a different liquid.

In the accompanying drawings, consisting of three sheets, Figure 1 is a sectional elevation of a centrifugal separator provided with my improvement. Fig. 2 is an elevation of one of the rings, having its peripheral portion corrugated. 3 is a top plan view thereof. Fig. 4 is a diagram showing the peripheral edges of several superposed rings and the layers of liquid in the corrugations thereof. Fig. 5 is a side elevation of a ring contracted neck 0, which contains the creamdischarge 0.

D are the pipes through which the skimmilk is discharged.

E represents the casing which surrounds the bowl; F, the cream-tray; G, the skim-milk tray, and H the feed-cup provided with the feed-pipe h. All of these parts maybe of any suitable or well-known construction.

I represents the inclined annular divisionplates or conical rings arranged in the liquidspace of the bowl and separated by spacing ribs or projections 2', so that these rings divide the liquid into numerous thin layers, which are arranged at a greater or less angle across the radial lines of the bowl. These rings are provided with corrugations j, forming channels in which the separated liquids are received and by which they are conducted to the edge of the ring.

In the construction represented in Figs. 1,

2, 3, and 4. the corrugations are formed in the outer or peripheral portion of each ring, and the outwardly-flowing heavy liquid is received in the channels in the lower side of the ring above each layer of liquid, as represented at 70 in Fig. 4, while the light liquid, which flows inwardly, is received in the channels formed 0 in the upper side of the ring below each layer,

as represented at Zin the same figure.

In the construction represented in Figs. 5 and 6 the corrugations are formed in the inner portion of the ring, and in the construction represented in Figs. 7 and 8 the corrugations extend from the inner to the outer edges of the ring. The corrugations or channels are preferably arranged radially; but they may be arranged obliquely or spirally, as rep- IOC resented in Fig. 9. These corrugations form channels which receive the separated liquids and conduct them in separate currents to the edges of the. rings, thereby preventing the separated liquid from meeting a current of a diiferent liquid flowing in the opposite direction,whereby a new emulsion would be formed and the separating operation would be correspondingly retarded. The corrugations in the rings therefore expedite the separating operation and efiect a more thorough separation, whereby the separating capacity of the bowl is materially increased.

I claim as my invention The combination, with a separating-bowl,

of superposed division-plates arranged in the liquid-space across the radial lines of the bowl, provided with corrugations or channels through which the separated liquids flow and communicating at their outer edges with a passage for the heavy separated liquids, substantially as set forth.

lVitness my hand this 17th day of March, 1891.
