Definitions

  • the invention relates to means for emptying the revolving drum ofva centrifugal machine.
  • the drum of a centrifugal machine with means for removing the substantially solid material accumulated on the inner drum wall, said means consisting of a plurality of disks having a smooth circumferential cutting edge and assembled on a shaft mounted in substantially parallel relation with the axis of the drum and adapted for movement towards and away from said inner wall.
  • said disks are toothed or otherwise provided along their circumference with a series of recurrent projections and recesses, and
  • Fig. 1 is a vertical axis sectional view of part of a horizontal centrifugal machine
  • Fig. 2 is a fragmentary sectional view along the line II-II in Fig. l,
  • Fig. 3 is a front view of a detached disk, drawn on an enlarged scale
  • Fig. 4 is a side elevational view of three disks
  • the revoluble drum or basket 6 Mounted within the stationary housing 5 of the centrifugal machine is the revoluble drum or basket 6. Rotatably mounted in a bearing 'I of said housing 5 is the casing 8 of a screw conveyor 9, the axis of which is in parallel relation with the axis of the drum 6. The shaft of the screw conveyor 9 is designated by I0.
  • radial arms 8a, 8b supporting a shaft II mounted in parallel relation with shaft I0.
  • shaft II Freely revoluble about shaft II are a plurality of disks I2a, I2b, I2c of equal sizes, each disk being provided with a circumferential series of radial fingers I3 of very hard material and of U-shaped cross-section.
  • the cylindrical body formed by these disks extends through the full axial length of the drum 6.
  • the disks I2 may be and preferably are provided with a bushing I I on which the disks are freely rotatable.
  • the disks may be and preferably are separated by more or less resilient spacing elements I2', shown more particularly in Figure 4.
  • the casing 8 is adapted by mechanism not shown on the drawing to be oscillated through a suitable angular distance in such a manner that the cylindrical body I2 composed of disks I2a,
  • 'Ille shaft IB is coupled with a transmission not shown, 10 so that the screw conveyor can be driven at a suitable speed.
  • the casing 8 is further provided with an axial slot I4 adapted to receive the stream of disintegrated material disengaged by the disks I2a,
  • the outer ends of arms 8a, IZb are formed as hooks, scrapers or the like extending circumferentially of the cylinder I2, so that the solid material accumulated on the inner drum Wall is also scraped off in the radial planes of 35 said arms, i. e. in the regions beyond the reach of the disks I2a,
  • the disks provided with recurrent projections and recesses along their circumference may a1- ternate with disks of relatively soft material and 40 having a smooth circumference.
  • the cylindrical body I2 on Shaft Il is composed of disks that are freely revoluble relative to one another and that they are provided with a cir- 45 cumferential series of teeth or like projections adapted to disintegrate the material when the disks are brought into frictional engagement with the layer of solid material accumulated on the inner drum wall. 50
  • the axis of the cylindrical body I2 is mounted So as to make a very small angle with the axis of the drum.
  • my invention is equally Suitable for a centrifugal machine hav- 55 ing a perforated drum as for a centrifugal separator, the drum of which has an impervious Wall.
  • the cylindrical body I2 may also be mounted so as to be adapted for rectilinear reciprocatory movement, the only requireshaft, the series of disks being bodily movable into and out of contact with the interior surface of the drum by adjustment of the cylindrical body.
