ABSTRACT:
Safety device for centrifugal separator for preventing a disassembly when the drum is rotating. Tipping lever 25 (FIG. 1) is fastened to the offtake 19 which is for removing separated liquid. The tipping lever extends through an opening 27 in hood 2 which is stationary. By magnetic attraction of a permanent magnet 14, which is mounted on the drum, the tipping lever is pulled inwardly so that it engages the inner edge of opening 27 and thereby locks the offtake on the hood. The magnet 14 extends only partway around the drum and when the drum is stopped the offtake can be rotated so that the tipping lever is out of the reach of the magnet 14. The opening 27 is elongated to permit rotating of the offtake.
