Solid bowl centrifuge with a paring disc

The innovation relates to a solid bowl centrifuge with a peeling disk * that covers the peeled material dissipates their hub. Centrifuges of this type are known, they have the disadvantage * that the water level cannot be changed in the centrifuge during operation. Solid bowl centrifuges are also known * where the water level can be changed * the known solution cannot be used with solid bowl centrifuges transferred with paring disc because you have the known device for changing the water level in these Can not accommodate centrifuges.

The innovation is based on the task * full jacket « formed with a paring disc so that the

The water level can be changed during operation. To achieve this object, it is proposed according to the invention to ensure that the peeling disk comprises an eccentric and that means are provided which allow the two parts to move relative to one another. The eccentric can be stationary and the peeling disk can be rotated relative to the eccentric, but the eccentric can also be rotated. Which of the two solutions is chosen depends on the options available, in particular on whether a solid-wall centrifuge is to be equipped with the innovation from the outset or with it at a later date. Both solutions are explained below using schematically illustrated exemplary embodiments.

Pig. I a vertical partial section through a solid bowl centrifuge with adjustable peeling disc, Pig. 2 shows a section along line A-B of Pig. I, Pig. 3 shows a vertical longitudinal section through part of FIG. 1 according to the second embodiment.

The feed pipe 2, which is used to feed the material to be centrifuged to the centrifuge, is provided with a cover plate jj, protrudes with its one end 4 into the conical shell space of the centrifuge 1 and is at its other end 5 with a lever 6 is provided which allows rotation of the feed tube. Appropriately, on the hub part 7 of the lever 6 or 2 line marks attached to the feed pipe, which in cooperation with a stationary mark determine the angle of rotation

inner end carries an eccentric 11 which is encompassed by a paring disc 12. The drum cover 1J, encompassing the peeling disk 12, is supported by a roller bearing 14 in the holder 10; When the feed pipe 2 is rotated relative to the eccentric 11, the water level of the centrifuge can be changed, since the space enclosed by the drum cover IJ is connected to the interior of the centrifuge 1 via openings 17. The peeling disk 12 has an inner cavity 18 which is connected to the circumferential surface 19 of the peeling disk 12 via a curved channel 20, so that the peeled material during the rotation of the centrifuge jacket via the channel 20, the cavity 18, the interior of the drain pipe 8 and the drain connection or the like 21 can be discharged.

In the case of the embodiment of FIG. 3, the feed pipe 2 ^{1 is} arranged in a stationary manner, ^{the outlet pipe 8 1} connected to the eccentric 11 'can be rotated by means of the lever 6' so that the over the driver 15 'in the radial slot 16 * of the cover plate J5 'Paring disc 2 secured against rotation' executes a radial movement when the drain pipe 8 'is rotated. The holder is marked with 10 *.
