Jen 11 and 12, which together form the drum 13. The drum half 12 is slidable on the Shaft 15 arranged.

In the upper part of the drawing the drum is closed and in the lower part it is open Condition shown. In the drum, a distributor cone 16 is arranged with a; Displacement body 14 is formed in one piece. The centrifugal material is located on the inside of the distributor cone supplied via channels 21 in shaft 15. Inside the distribution cone is. another displacement body 17 arranged.

Openings of an inlet pipe open into the channels 21 19, which is arranged centrally in the longitudinal bore 18 of the shaft 15.

From the inside of the distributor cone 16, the material to be thrown is gradually and without the occurrence of Vortex brought to an area where the centrifugal forces are sufficient to remove the solids from the Separate liquid. As soon as the material to be thrown leaves the edge of the distributor cone 16, it is of the displacement body 14 out and forms on this a thin layer, which is responsible for the separation the solids from the liquid has a very beneficial effect. The clarified liquid is through axial Outlet bores 42 in the fixed drum shell 11 drained away.

At least one degassing channel 43 in the displacement body 14 connects the inlet area of the material to be centrifuged in the drum 13 with the exit area of the clarified liquid, so that possibly existing air bubbles can be discharged through this channel.

The displacement of the drum half 12 on the shaft 15 is carried out by means of a hydraulic medium achieved, which is introduced into the pressure chambers 30 and 31 of a pressure cylinder 46. The printing cylinder is firmly connected to the movable drum half 12 and can also be formed in one piece with this be. The piston rod of the pressure cylinder is formed by the shaft 15. This shows you Ring flange 47 which forms the piston head of the pressure cylinder. When the hydraulic medium is passed into the pressure chamber 30, as in

ίο the upper part of the drawing is shown, the Drum closed; if, on the other hand, it is directed into the other pressure chamber 31, the drum is opened, as shown in the lower part of the drawing. The pressure cylinder 46 is through a driving pin 48 non-rotatably connected to the annular flange 47 and thus to the shaft 15.

The centrifuge can be operated discontinuously, i. H. that the centrifuge is closed Drum receives a certain batch and after a certain time and a certain Speed is opened and the deposited solids are discharged. However, it is also possible to operate the centrifuge continuously, i.e. that the drum after reaching a certain Speed to a certain gap width of z. B. 1 mm is opened. This operating mode results in a much higher throughput than in the previous operating mode. The gap width can be adjusted by a exchangeable stop 50, which is arranged on the driver pin 48. It is but also possible to use a contactless limit switch, e.g. B. to provide a magnetic switch 51, the is arranged on the pressure cylinder 46 or the housing of the centrifuge and the supply of the hydraulic Medium controls.
