Centrifuge with automatic cleaning priority Jrankreioh, from 7 «Septembea? 1965

It is known that centrifugal separation is carried flussigen, Tiskösen and fixed ropes much better than running in Schleudergefassen with than removal by tangential "SaugYorrlehtungen ₉ which latter the laughing part loading • Itzen" that ■! · Virbel and a "Durohrühruag of fluids cause * which for divorce are unfavorable.

Furthermore, in the case of a long centrifugation, it is not necessary to clean the precipitate during operation while the primary liquid is being supplied to make without loss of this. The supply must therefore be

placed in order to obtain a relatively dry precipitation »

The invention aims to remedy these disadvantages. For this she has a centrifuge for her subject, welohe formed by a conical centrifugal vessel with a large opening is, which the cleaned liquid by overflowing with With the help of radial nozzles, which with a system with a tangential bucket with intermittent automatic feed and return, which occurs during the "operation and the automatic one with continuous fluid supply Cleaning of a thick or viscous deposit is permitted, as well as with further radial adjustable nozzles aod one additional annular partition to remove the heavy Liquid in the case of separation of two liquids of different densities are combined

The above basic form of the centrifuge can be given various designs the same the conical centrifugal vessel is divided into two or three compartments by one or two annular partitions, which are provided with openings and which cross over the heavy liquid file and the · precipitate in you last department allow which smaller iat.

On the wall of the partition and on the side The larger section is attached to a radial drainage door, which by centrifugal force when the 3chleudergefiksee drifts away the lightest liquid «

If a second, heavier liquid is to be discharged separately, there are additional nozzles that can be adjusted in height on another annular partition in the second intermediate

department attached.

Indian on the side of the base of the cone the small section of the centrifugal vessel is a large intermittently working and movable spoon arranged to remove the thick or viscous precipitate pressed against the side wall of the centrifugal vessel.

Another embodiment takes this Department has one or more small suction devices, which continuously or discontinuously the excess liquid or drain the second liquid, which is heavier than that discharged through the nozzle is to this department to dry before or while working with the large spoon or to recover the denser liquid.

The axis of the centrifuge can be vertical or * horizontal lie, but this latter location is a better one Discharge of the precipitate is permitted by gravity when separating the thicker liquid.

Thanks to the ring-shaped partition and the conical shape of the centrifugal vessel, the thick precipitate moves along its deposition on the wall of the centrifugal vessel through the openings of the annular partition wall or the annular partition walls and reaches the small compartment, where it is of the Spoon is vacuumed regularly. The deposition of the precipitate on the wall of the centrifugal vessel and the discharge of the Liquid is therefore not disturbed, although the precipitate is removed by the spoon.

The invention is explained below by way of example with reference to the drawing.
