Definitions

  • This invention relates to centrifugal machines and is an improvement of the device described in my Patent No. 1,979,909, issued November 6, 1934.
  • the capacity is increased and the time required for precipitation is reduced by leading the precipitable substances at the highest possible velocity in the direction of the centrifugal effect direct to the places where the solid substances collect and allowing the incompletely dry substances to slip back to the said places.
  • the solid particles to be precipitated vary greatly in mass and size and the finest particles separate from the liquid only with great dim@ l5 culty when the time allowed for precipitation is short, and thereby prevent a dry ejection of the solid substances.
  • the finest particles can thus be separated from the liquid and only comparatively dry substances 5 can be transported to the place of discharge.
  • Both rotary members can be formed framelike or asvcasings and the individual movement of the containers or cells in which the mixture is fed and be effected by any suitable means.
  • the outer member is in the form of a closed casing and the inner member takes the form of a drum with open hollow members extending to both sides in the axial direc- 15 tion.
  • Figure l is a longitudinal section according to line A-B of Figure 2 and through a centrifuge with quickly rotated outer casing and a slowly rotated inner drum which turns about a cross axis.
  • Figure. 2 is a longitudinal 'section according to line C-D of Figurek 1.
  • Figure 3 isa cross-section according to line 25 E-F of Figure l.
  • Figure 4 is an enlarged representation of the ing tothe cross-sectional Figure 3.
  • Figure 6 is a section throughthe container walls with warped surfaces at that side which is opposed to the direction of rotation.
  • Figure 7 is a vsection through the container walls 3 5 with sieve surfaces on that side which is opposed to the direction of rotation.
  • Figure 8 is a section through a drum with tiltable containers according to line I-K of Figure 9, and 40 Figure 9 is a section according to line L-M of Figure 8.
  • a casing I rests in aquickly rotatable manner in bearings 2 and 3 and is driven by means of a pulley 4.
  • a pulley 4 By means of an 45 externally fixed'shaft 5 and reduction gearing 6,
  • a'drum II is slowly rotated from the quick casing rotation through a toothed ring I2 provided on the drum periphery.
  • the drum Il v has a shaft I3 mounted in bearings Il of the 50 v casing I and performs aslow individual movement with thesaid shaft.
  • An inflow bracketIS for the mixture to be'separated projects into the central part of the drum II and has guide nozzles i8 which are directed towards the drum cells or con- 55 tainers I9 lying inside the drum II over the whole mush can thereby precipitate themselves theren periphery thereof.
