PATENT OFFICE.

The present invention relates to

Centrifugal devices

for divorce from

Liquids of different specific gravity, which have the purpose of making them Arrangement of two or more centrically nested centrifugal drums of different diameters, to which the liquid is supplied in certain unequal amounts, with the same Work effort compared to the known centrifugal devices a higher performance to reach.

A centrifugal device of the new arrangement is shown in the accompanying drawings, namely in Fig. 1 in a cross section, in the upper half according to ' ABC of Fig. 2, which is a view from below of the lid in partial section, in the lower half according to DEF of FIG. 3, which shows a plan view of the bottom, while in FIGS. 4 to 7 embodiments of the inlet chamber for the liquid which can be seen from FIGS. 1 and 2 are shown.

In the device according to FIGS. 1 to 3, for example , a second centrifugal drum b is nested in the centrifugal drum a, the drum α with the cover c, the drum b with the base d in one piece and both drums through the cover and base outside and closed against each other. Both drums are fed from the feed pipe e through the inlet chamber f . The inlet pipe e is closed at its lower end, with which it protrudes into the inlet chamber f , and allows the liquid to flow out through lateral openings in radially directed jets indicated by arrows. The inlet chamber / g by partitions, and though as used in the present Examples only in two mutually nested centrifugal drums, in two divisions gröfsere h z and two smaller divisions; the contents of which are passed through the bores k from the larger compartments h into the outer drum α and through the bores / from the smaller compartments i into the inner drum b .

The liquid flowing out of the inflow pipe e evenly and under constant pressure is now also taken up in correspondingly unequal quantities by the unequal sections h and i rotating past in the chamber f and supplied to the associated drums α and b in an amount corresponding to their capacity. The liquid is separated in each of the two drums separately in the known manner, so that the specifically heavier liquids collect on the inside of the surrounding walls of the drums α and b and pass through the bores m and m ' into the common drainage channels η which they are discharged from the drum into suitable collecting vessels, while the specifically lighter liquids through the holes 0 and 0 'into the common

Channels ρ arrive and are also fed out of the drum into suitable collecting vessels. Known centrifugal devices in which two or more centrifugal drums are nested in one another, the present differs in that with those a single common feed pipe for the liquid to be separated is available and this runs through the drums one after the other, so that from the individual drums only the light parts of the liquid are drained separately and immediately outwards, while the heavy parts get into the next drum and are only led outwards from the outermost one. here on the other hand, the liquid to be treated is supplied separately for each drum, and the light as well as the heavy components of each drum are separately carried outwards, without that there is a connection between the individual drums. Instead of dividing the inlet chamber into unequal compartments, i. H. bigger ones for the Outer and smaller ones for the inner centrifugal drum, the inlet chamber can like this is shown in dash-dotted lines in the right half of Fig. 2, also in a specific one Number of equally large divisions, which are also all the same Absorb amount of liquid, but the individual drums with different Feed quantities of liquid so that in the outer drum a larger number of compartments in the present example four, in the inner drum a smaller number, in the present example Examples of two divisions, dissipating their contents. Likewise, what is not specified in the drawing, the separated liquids, instead of immediately after leaving the individual drums in common To get channels, also only enter into spatially separated channels from which they are then discharged into the collecting vessels. Each of the two centrifugal drums can also be used to increase their performance Wings and inserts, as such 'have become known through numerous patents, equipped will. The introduction of the drums a and b to be cut liquids may also be in the in the Fig. Carried out 4 to 7 manner shown by once the liquid from the inlet chamber f by producing a gleichmäfsigen liquid pressure by different grofse holes in the walls of the chamber to individual drums in quantities determined for the same (Fig. 4), or by arranging an equal number of inlet chambers corresponding to the number of nested drums concentrically around and above one another, into which the determined quantities of liquid for the individual drums are fed through a feed pipe become (Fig. 5); finally in such a way that the inflow pipe, as in FIGS. 2, is closed at its end and has one of the number of openings or rows of openings above one another, corresponding to the number of nested drums, from which the amount of liquid intended for the individual drums flows in radial jets into sections of the inlet chamber separated by disk-shaped horizontal partitions, in order to be fed from there in special bores to the individual drums (Fig. 6). The inflow pipe can also consist of two pipes pushed through each other, of which the narrower and longer one is open at the bottom, while the further and shorter pipe surrounding it has openings above its bottom through which the outflow of the liquid takes place in radial jets ( Fig. 7). - All the embodiments of the inlet chamber achieve the intended purpose of achieving a higher performance of the centrifugal device with the same amount of work by feeding certain unequal amounts of liquid into the individual centrically nested centrifugal drums. Since the performance of a centrifugal machine depends only on the size of the centrifugal drum and its speed of rotation, while the thickness of the liquid layer in the drum has no influence on the performance, the performance of the device described is of the same size as that of an ordinary, simple centrifugal drum so much greater than, in the present case, ■ the efficiency of the nested drum is b . The efficiency of the centrifugal machine therefore generally increases the more drums are nested in one another. Patent-to sayings: i. Centrifugal device for the separation of liquids of different specific gravity, with two or more centrifugal drums, nested in a concentric manner and are each provided with a special liquid outlet channel, thereby characterized that each of the drums is provided with a special liquid supply is (Fig. ι to 3). 2. In the case of centrifugal devices according to claim ι the arrangement of the feeding of the Inlet chamber providing centrifugal drums, characterized in that the inlet chamber protrudes into the inlet chamber at its The lower end of the closed inflow pipe feeds the liquid through side openings flow out in radially directed jets, and the inlet chamber through partitions parallel to the axis into a number of different compartments corresponding to the number of centrifugal drums Size is divided, which during the rotation the. for the individual Drums take up certain amount of liquid, which is fed to the drums through special bores, or in a number of equally large compartments, which also all take up the same quantity of fluid, but the individual ones Feed the drums with different amounts of liquid by placing a larger one in the outer drum and one in the inner one Drum removes its contents from a smaller number of departments (Fig. 1 and 2). 3rd embodiment of the inlet chamber for feeding the centrifugal device according to Claim 1, characterized in that the liquid from the inlet chamber after Creation of a uniform fluid pressure by means of bores of different sizes in the walls of the chamber the individual centrifugal drum !! in for the same specific amounts is supplied (Fig. 4). 4th embodiment of the inlet chamber for feeding the centrifugal device according to Claim 1, characterized in that one of the number of nested Centrifugal drums corresponding equal number of inlet chambers are arranged concentrically around and on top of each other, in which through a feed pipe the specific liquid quantities for the individual Drums are fed (Fig. 5).
