Application November 7, 1957, Serial No. 694,990 6 Claims. (Cl. 23327) This invention relates to the art of centrifugal separators for materials of different densities.

The invention is directed at providing a device adapted to separate gases, liquids, or finely divided solids. The device is adapted to separate mixtures of steam vapor and water, oils containing constituents of different densities or viscosities, dusts or powders of-diierent sizes entrained in streams of air or liquid, etc.

A principal object of the invention is to provide a separator in which a vortex of great rotational velocity is obtained without use of baffles and impellers.

A further object is to provide a separator which has a dynamically balanced rotatable vortex chamber to increase the centrifugal forces upon the constituents to be separated.

A further object is to provide a separator including a turbine stator supporting a uid driven rotor, with a vortex chamber for separating material contained in the rotor.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In Figs. 1 and 2, there is shown compressor 21 provided with an air inlet 22. The compressor serves to compress the air and deliver it at high pressure to the fluid divider shell 24. Valve 25 controls the air iiow from the compressor via pipe 27. A gauge 28 indicates the pressure in the tank of the compressor. The compressor is driven by a motor 30 which is energized via wires 32 controlled by switch 31. The divider shell '24 i's connected via'pipesA-33 and 34 to two further divider shells 35, 36 provided with

pressure gauges

39 and 40.

Y 2,875,949 Patented Mar. 3, 1959 Valves 41 and 42 control the flow of compressed air through pipes 33 and 34.

Branch pipes

45 and 46 are connected from divider shell 36 to stator ring 48 of the separator.

Branch pipes

50 and 51 are connected from divider shell 35 to another stator ring 49 of the separator. Stands '52 and 53 support the pipes between the divider shells 36, 36 and the stator rings.

T-he stator ringsv are mounted in retainers 55. The rings rest on a base plate 56. A rotor 60v is freely rotatable within the stator rings. The rotor has inlet tubes orv pipes 61, 61a at opposite ends for receiving the material to be separated in a chamber within the rotor. Inlet pipes 61 and 61a terminate in

shells

64 and 65. These shells have apertures 67a in their inwardly facing sides 66 in which sides are mounted bearing rings 67. The ends `of the inlet pipes are journaled to rotate in .thesebearings Inlet feeder pipes 68 and l69 communicate through chambers in the

shells

64, 65 with the open ends of pipes 61 and 61a. These pipes are branches of the common feeder pipep70` which is supplied with the material to be separated froma hopper 71. .A 'valve 72 in pipe 70 controls the ow of the material through pipe 70.

Two pairs of

pans

74, 76 and 74a, 76a are provided on each side of the stator rings. These pans are .arranged to receive the separated material discharged from the rotor. Outlet pipes 80, 80'a are connected to

pans

74, 74a and outlet pipes 81, 81a are connected to

pans

7,4 and 76a. Pipes 80, 80a j-oin at the common outlet pipe 84. Pipes 81, 81a join at the common outlet pipe 85.

vThe structure of the rotor 60 is best shown in Figs. 3, 4 and 1l. The rotor includes an outer ringl 87 formed with a succession' of vanes 88 arranged as a chain of Vs with central connecting walls 89. A vgenerally'cylindrical shell is formed by a pair of cylindrical shell members 78,` 78' having flanges 90 on the inner ends thereof. Bolts 91 secure the ilanges of the two shell members together with the ring 87 disposed therebetween. yThe

shell members

78, 78a have inwardly tapered ends 781.v

Tubes or pipes 92.and 92.a are concentrically disposed around pipes 61 and 61a. Radially disposed ribs 93 secure the

tubes

92, 92a within the'shell members. One end of each

tube

92, 92a extends out of the respective shell member and has a ange 94 disposed thereon. These .flanges are slightly spaced from' the open len ds of lthe Vtapered portions 78h ofthe shell members.A Spaced from flanges 94 are other flanges 95. These anges have smallerV diameters than flanges' 94. Flanges 95 are spaced from the =ope`n ends of tubes 92 andp92a. `

Rings

96 and 96a having helical grooves V97 therein' are mounted on ber 98 is thus formed within the rotor. `This chamber communicates via the helical passages with. the annular openings between

tubes

92, 92?L and

shell members

78, 78a. The Vchamber 98 also communicates with'the'an nular openings between tubes 61', 61a and

tubes

92, 92a. In Fig. l1 the showing of rings 96 and 96EL is lomitted in order'to show the helical paths P of material flowing from chamber 98 to the two outlets -at each end of the rotor. The path of flow of material intothe rotor is shown by dotted lines A and the paths of .the separated material is shown by dotted lines B and C respectively.v Chamber 98 serves as a mixing 'and comminuting chamberfor the material entering via pipes 61 and 61a;

In Figs. l, 2, 5 and 6 are shown the arrangement of the '

inlet pipes

68 and 69 which are connected between feederi pipe 70 and the shells 64 and6,5.l -vThe endsof pipes 61, 61 t into apertures 67a and are rotatable therein on bearings 67 shown in Fig. 2. A pressure gauge 73 may be provided in pipe 70 for indicating the pressure of materialiowing therethrough into-

pipes

68, 69.

In Figs. 7 and 8n are shown the details of the stator rings 48 and 49. These rings are endless tubes. Pipes 45 and are 4conencted at diametrically opposed points to ring 48`and

pipes

50, 51 are connected similarly to 'ring 49. The rings have each a plurality of nipples 47 opening in their lower sides. The rings are secured to an outer band 54 which has a plurality of spaced passages 57 communicating with nipples 47 in the

rings

48, 49. Another band 58 provided with pairs of diagonally extending passages 59, l59a4 is disposed inside band 54. Band 58 is prevented from moving with respect to band 54 by loosely vcontacting serrated plates Y62 and 62a respectively mounted on the sidesA of band S and rings 4.8, 49. A handle 63 has laterally disposed bars 632.t connected to both plates 62 on band 58. The teeth yof plates 62, '62"L are rather loosely engaged so that the inner band 58 can be moved slightly circumferentially with respect to band 54.V At one 'end of the movement of band 58 passages 57 communicate with passages 59 and at 'the other end of movement of the inner band passages 57. communicate with passages 59a.

Rings

48 and 49 are prevented from rotating by their mounting in retainers 55.

Rotor 60 is rotatably mounted in the band 58. When the handle bars 63a are vertical, passages 57 and 59 are in communication, so that streams of air at high pressure emitted from passages 59 impinge on vanes 88 and cause the vrotor to rotate at high speed. When it is desired to the rotor, the handle 63 is moved to cause passages 5 7 to communicate with the passages 59H. The air streams will now be directed oblqnely at the vanes 88 in directions which will oppose lthe rotation of the rotor so that thel rotor is gradually brought to a stop. The device is thus provided with an air braking means. The device uses compressed air to rotate the rotor and to brake the rotor.

lIn Figs. 1, 2, 9 and 10 are shown the

pans

74, 74a which receive the separated material from rotor openings adjacent anges 94 of the rotor. These pans have cavities which communicate -with outlet 84 via

pipes

80, 80, Qn its inner side 74 each of these pans has an opening 82 which is large enough to pass the

flanges

94 and 95 of the rotor. The outer side 83 of each of pans 74, and 74. has an opening 86`best shown in Fig. 2, which opening is just large enoughV to pass the flange 95 at each end of the rotor. Flanges 94 are rotatably disposed in the pans 74, 74' and close the openings 86; The outer ends of tubes 92 and .92a extend through openings 86 and terminate in pans 76 and 764. These pans are connected via pipes 81, 8,1 to outlet pipe 85. The outer sides 76' ofpans 76, 76e have openings 79 through which pass the ends of pipes 61 and 61a' respectively. Flanges 95 are disposed in

pans

76, 76%l and are located adjacent sides 76. @penings 77 in the inner sides of pans 76, 76ab are just large enough to pass the flanges 95 of the rotor.

By the arrangement of the pans and their associated outlet pipes, all materials separated in the rotor pass in parallel streams to

pipes

80, 80 and 81, 81e.

In`operation of the apparatus, the rotor will be driven by compresed air provided by compressor 21 and fed via the stator rings. Material to be separated such as finely divided solids in a liquid carrier will pass from container 'Iliinto the chamber 98 in the rotor. The material passes i'ntwo opposed streams into the chamber where a turbulent condition is established. The rapid rotation of the rotor imparts a rotating vswirling motion `to the mixing s'tr'amswliich divideintoequal parts passing through the two'lrelical passages 97 lin tl1`e`tw`o rings 96 vand V969'l best shown Vin Figs. 3 and 12. Due to the different densities and of the substances in l'the rotating streams, particles "of greater densityv pass out of the radially outerf'spaees between the sh'ell members 78, 78land-tubes 92, 925 into

pans

74, 74a. Particles of lesser density will pass out of the radially inner spaces between tubes 61, 61Bl and

tubes

92, 92a into

pans

76, 76a.

Instead of a hopper 71, there may be provided a closed container supplying a mixture of gases, or liquids under pressure to the rotor for separation thereby.

The separated materials passing through

outlet pipes

84 and 85 may be collected in suitable containers. If desired, the rather high kinetic energy imparted to the streams of materials in the several outlet pipes may be fed to suitable turbines or other engines to perform useful work.

It will be -noted that the entire assembly of the rotor 60 has a balanced symmetrical structure. This permits the separator to operate at high speeds of the order of 10,000 or more R. P. M. The high speed of rotation of the mixture of oppositely directed streams in chamber 58 causes a very tine comminution of the streams to take place so that the streams passing through

rings

96, 96 are really tine sprays of minute droplets rather than heavy streams of solidly ilowing material.

If the apparatus be used primarily for performance of useful work bythe several high pressure streams issuing

Afrom outlets

84 and 85, the apparatus may be regarded as an energy converter, in which the latent energy in the compressed air which drives the rotor is converted to kinetic energy in the streams of lluid in the several outlets.
