Below is an example embodiment of the new ones Centrifuge explained in more detail with reference to the drawing.

The figure shows a diagrammatic view of the centrifuge with partially closed caps.

The cross section of the centrifuge housing 21 is square at least in the upper area. On the upper edge of the centrifuge housing 21, essentially trapezoidal flaps 80, 81, 82, 83 are mounted pivotably about horizontal axes 87. Each flap is arranged with its long side corresponding to the length of the side wall of the centrifuge housing via two hinges 88 on each of the centrifuge housing 21. If the flaps are inclined by about 50 °, they form a filling funnel with a wide cross-section. In this open position, the flaps rest on rubber buffers which are arranged on stops attached to the inner wall of the centrifuge housing. Me both side edges of the flap 82 are gripped from below by one side edge of the flaps 81 and 83, while the respective other side edge of the flaps 81 and 83 is gripped from below by the side edges of the lowermost flap 80 . %

After loading the centrifugal drum , the bottom flap 80 is attached to it and via an axi. The lever 90 protruding beyond the centrifuge housing 21 is pivoted up into the horizontal position by means of a hydraulic pressure cylinder 91 engaging the lever 90. The flap 80 takes the two overlying flaps 81 and 83 and these take the flap 82 with them, so that the drum space is closed. As long as the cylinder 91 is under pressure, the flaps 80 - 83 are held in the closed position. After the centrifugal drum has come to a standstill, the pressure cylinder 91 is controlled in such a way that the pressure medium can flow out and thus the flaps 80-83 sink into the funnel position.

The flaps 80 - 83 are expediently arranged in such a way that that they are in the funnel position and with the centrifugal drum closed at the bottom with their lower sides stand at a short distance above the upper edge of the drum shell so that when the drum shell is raised the flaps 80 - 83 can also be lifted.

The two mutually parallel axes 87 are arranged at the same height, while the axis of the flap 82 higher by the wall thickness of this flap and the axis of the lowermost flap 80 by a flap wall thickness

The drive motor can be switched on by a switch 93 arranged on the centrifuge housing 21, which is then actuated by a tongue 94 attached to the flap 80 when the flap 80 and with it the the other flaps are in the closed position.
