Definitions

  • This invention relates to new and useful improvements in centrifugal separating machines and more particularly to continuously operable machines of this type which are well-suited to separating a Variety of granular, fibrous, or crystalline solids from liquid mixtures containing the same.
  • a principal object of the invention described herein is to design a machine of this type in which means is provided for mixing the relatively wet strata of caked solid directly adjacent the basket with the drier solids above it as the cake is discharged so that lumps or masses of sticky crystals which build up and break off will not form on the dry housing wall adjacent the basket.
  • a still further object of the invention is to design a centrifugal machine of the type described which is durable and rugged in construction, which comprises relatively few component parts of a simple nature which are readily accessible for cleaning and inspection, which may be easily and simply disassembled for repair and replacement of parts, and will accordingly be relatively inexpensive to maintain and which can be economicmly manufactured and assembled.
  • FIGURE 1 is a part sectional, side elevational View of my novel centrifuge showing the pusher in forward position.
  • FIGURE 2 is an enlarged, fragmentary, sectional view thereof, the pusher being shown in rearward position.
  • FIGURE 3 illustrates schematically the manner in which the pusher is actuated forwardly by a hydraulic pump and is permitted to return under pressure of the material feeding into the basket.
  • FIGURE 4 is a sectional View illustrating schematically one of the multiple way valves which is employed in the system.
  • FIGURE 5 is a sectional View illustrating schematically another valve which is employed in the system to control the valve shown in FEGURE 4.

  • a dri-'1e sheave 15 mounted on the reduced end 14h: of the shaft 11i is connected by belts 16 to the shaft of a motor 17 which is adapted to drive the shaft at relatively high speeds.
  • a pressure fluid cylinder 13 Formed as an integral portion of the shaft 14 is a pressure fluid cylinder 13, the two portions of which may be bolted together as at 19.
  • a pusher control assembly C of conventional design is provided to control the forward operation of the piston 2u and the piston rod or shaft 22 is transversely bored as at 23 and longitudinally bored as at 24 to admit pressure fluid from the assembly C to the outer face of the piston 2t) so as to drive the latter forwardly to the piston in which it is shown in FIGURE l.
  • a positive displacement constant delivery pump d4 (FiGU-RE 3) supplies the pusher control assembly in a manner which will later become apparent.
  • the tubular shaft 14 extends from the drive housing 11 into a wet housing 26 which is bolted to the housing 11 and a drum ⁇ or basket B is keyed thereon as -at 27, the basket B comprising a radial end wall or hub 28 with a perforated cage 29 having a screen 3d supported therein.
  • a frusto-conical pusher Wall 31 is keyed as at 32 to the tapering end of the shaft 22 which extends into the wet housing 26 beyond the shaft 1/1, and a nut 33 threaded on the end of fthe shaft 22 maintains the Wall 31 in position.

  • the funnel 35 it will be observed, is concentric with the screen 39 and is substantially co-exten? sive therewith.
  • the annular ⁇ flange portion 35a of the funnel 35 terminates a spaced distance from the basket 30 and serves as a leveling ring.
  • the outer end wall of the funnel 35 is bored las at 33 to freely admit the slurry supply pipe 39 and the interior wall thereof is recessed as at 4d to carry a pair of superposed frusto-conical screens 41 and 42, the top screen i1 being a woven screen and the under screen 42) which supports the screen 41 being a mesh screen.
  • Connecting with the inner edge of the recess 4@ are anguiar passages 43 which lead through the flange 35a of the funnel and communicate with the passages 44 through the flange 31a of the pusher wall 31.
  • the outer end wall of 'the Wet housing 26 terminates short of the basket B and a throw-off ring 46 including an outwardly tapered flange 46a extending into a dry housing 47 is provided on the outer end of the basket B.
  • a frusto-conical baille member 49 Supported outwardly of the flange 46a to rotate with' the basket B is a frusto-conical baille member 49 which includes a lateral ange 49a projecting radially inwardly beyond the screen 30 to channelthe solids discharged down to the passage 50 defined between the rearwardly and inwardly extending portion of the baffle 49 and the ring 46.
  • the baffle portion 49 is secured to the base of the member 46 by widely spaced lugs 43 which also support a forwardly and outwardly extending truste-conical baffle member 51 which directs the flow -of solids from the annular passage 50 to the dry housing proper.
  • the architects 49 and 51 effect a through intermixture of the relatively wet solid particles immediately adjacent the screen and the relatively drier particles inward thereof in a manner which will be later described.
  • the particles which were disposed in the caked mass immediately adjacent the screen may have a residual liquid content of from 4% to 6% by weight, and this is what is meant by the term relatively wet as used in the specification and claims.
  • the liquid content of the solid particles in the cake which are located radially inward of these particles will be 1% to 2% by weight and these particles will be accordingly termed relatively dry.
  • the mixture may be Washed in the pre-draining stage of centrifugation by the laterally directed spray from a hose 52 which enters the stationary supply pipe 39 through a seal 53 and has a nozzle 52a on the end thereof for directing the wash liquidto the solids on the sides of the funnel 35.
  • the spray from a second wash hose 54 can be directed to the material on the inner portion of the screen 3i) to remove any remaining impurities.
  • Partitions 55,56 and 57 separate the wet housing 26 into compartments 58, 59 and 60 which can be drained olf separately through the discharge pipes 61 and, as will be apparent, the so-called green and wash liquids may be segregated in this manner.
  • a conveyor (not shown) may be provided in the lower portion of the dry housing to carry voff the dried and interrnixed crystals.
  • the pusher wall 31 is shown in rearward position in FIGURE 2, and it will be clear that ⁇ this wall is moved forwardly to the position in which it appears in FIGURE 1 when pressure iiuid reaches the rear face of the piston through the ports 23a, 23, and 24, and exhausts from ⁇ the front of the piston through the passages and 25a.
  • This pressure iiuid is supplied from a reservoir 62 ⁇ (see FIGURE 3) through lines 63 and 63a by 'the pump 64 which forces the fluid through a multipleway valve 65 and thence into the colllection chamber 66 in the collector C.
  • the valve 65 (see FIGURE 4) is formed with an in- 'terior cylinder 69 in which is a slide 70 having lands 71, 71a, 72, and '73. Passages 74, A75, 76, '76a and 77 which communicate with the lines 63, 63a, 68h, 68a and 68, respectively, lead into the cylinder as shown, and in the position in which the valve is depicted the lines 63 and 63a and 68V and 68a, are clearly in communication, and the piston 20 is accordingly moved forwardly.
  • the position of the member 70 is controlled by another multiple-way valve 78 which has a slide 79 in the cylinder -80 formed therein.
  • the one end of the slide 79 which vhas interior lands S1 and 82 extends from the valve housing and has spaced-apart flanges 84 thereon.
  • a pin 85 Xed on the shaft 22 ⁇ and movable in a slot 85a in the shaft 14 has an annular ring 851; disposed between these flanges 84 and clearly as the piston 20 moves forwardly, will -tend to force the slide 79":to the right.
  • Passages 86, 86a, 87, 88 and 89 communicate with the interior of the cylinder 8G, the passages 86 and 86a communicating with a line 90 leading to the reservoir, the passage 87 communicating with a line 91 leading to a passage 92 in the one end Wall of the valve 65, the passage SS communicating with a line 93 leading to the line 63, and the passage S9 communicating with a line 94 leading to a passage 95 in the opposite end wall of the valve 65.
  • the lines 93 and 94 are in communication to keep the valve 70 in the position in which it is shown.
  • a conventional relief valve 97 which interposes resistance in the line 68a leading to the reservoir 62 can be cut in to slow the return rate of travel of the piston 20.
  • the cake will be permitted time to build up to the leveling ring 35a so that it will have a maximum retention time on the screen 30.
  • the ring 85b will, of course, return the slide 79 to the left yback to the position in which it is shown in FIGURE S and the slide 70 will accordingly be returned to the left as shown.
  • the stroke of the continuously reciprocating wall 31 is such as to discharge only the front portion of the caked solids S which are virtually free of liquids lto the dry housing 47.
  • the sugar slurry or massecuite reaches the interior of the basket through the stationary pipe 39 and funnel 35 which gradually accelerates the mixture prior to discharging it through the passages 37 to the screen 3l).
  • the greater proportion of mother liquor is drained off to the wet housing 26 through the screens 41 and 42 prior to the time the mixture reaches the screen 3d and a portion of the washing operation to remove impurities not carried olf with the mother liquor can also -be carried out during this pre-draining operation.
  • Liquid pre-drained through the screen 41 travels rearwardly through the meshes of the screen 42 which is within the recess 40 and thence proceeds through the passages 43 and 44 to the chamber 45 rearwardly of the pusher wall 31.
  • the wash hose 52 delivers a prescribed spray of water to the mixture on the screen 41 which is insufficient to ilood the retained solids such that dilliculty will be encountered in pushing them when they reach the screen.
  • the solids reach the latter screen 3i)
  • the portion 49ay of the baille 49 catches and dellects the relatively dry particles inwardly to the channel 50 so that they pass through ⁇ and become thoroughly intermixed with the wetter particles.
