Description

Facility for emptying centrifugal drums. Centrifuges, at which can be lifted off the drum base with a hoist for the purpose of emptying the screen or can be pulled down against ühn are known.

For b.-ickendes centrifuged material you have to loosen the solid centrifuged material Mass in the drum inner wall also already hung chains, their hanging down After the drum was lifted off, the ends were pulled against the center of the drum in order to avoid the To detach the mass from the drum. Inlay tissues are also known that are at the top Are attached to the end of the drum and eject the goods when they are lifted.

The essence of the invention is that one is used to lift the sieve jacket Lifting device ditnendes from the drum base is equipped with a push rod with the per se known Abstroifketten or rings is connected, so that the latter be held when lifting the sieve drum beyond a certain point, thereby causing the evacuation. It can therefore be an overhead crane that has one Push rod carries, for lifting and emptying the drums of a whole series of Serve slings.

The drawing illustrates the invention in two exemplary embodiments, namely Fig. i and 2 are longitudinal sections of a standing sling and ° its excavated Sieve jacket when using emptying chains or ropes, Fig. 3 and q. appropriate Cuts when using an emptying ring.

The first version is in the outer jacket i the Centrifugal drum an insert screen jacket2 is used, which is in operation by bolt 3 is held and is closed at the top by a cover ring 4 so far, as is necessary to hold the goods in place when spinning.

For the purpose of emptying the centrifuged material, the bars 3 withdrawn, and then on the insert screen jacket 2 is shown as a rope mechanism Lifting device 6, 12 hooked.

Then the sieve jacket 2 is pulled up away from the bottom 5 and moved sideways. The hoisting rope 6 runs around a roller of a trolley 7 which is provided with a push rod 8 on which the sleeve g of the ropes 6, 12 is guided. At the lower end of the rod 8 ropes 13 can be suspended, which are fixed at io at the lower edge of the insert 2 and at the upper edge of the insert at. ii are releasably clamped.

Now the insert sieve shell with the centrifuged material (Fig. 2) continues raised, the tensioned ropes 13 tear the drained material out of the drum.

In the second embodiment, the clearing ropes 13 are replaced by a Stepped into the emptying ring 14 that fits into the sieve insert 2. This is on the bumper 8 is attached with ropes 13 to prevent it from falling off when being thrown maintain. It is raised to the maximum position (_A.bb. 4) when the ice set is raised the rod 8 retained so that the material to be thrown from the insert jacket 2 is ejected will.

In a meaningful redesign, the new facility is also for other spinners can be used without further ado.

Claims (1)

PATENT CLAIM: Device for emptying centrifugal drums, in particular for baking or matting loads, with a sieve casing that can be lifted off the drum base by a hoist and with 'emptying chains or rings for loosening the goods from the sieve casing, characterized in that the scrapers (i3, 14) with a push rod (8) standing axially to them are releasably connected to this lifting device (6, 7) so that they are held in place when the screen jacket is pulled up.
