Definitions

  • the present invention pertains to the art of centrifugal separators designed to effect separation of solids from a liquid, or separation of solids from a mixture of liquids. It pertains to the type ,of centrifugal inwhich solids are intermittently vdischarged through valve-controlled discharge passages in the wall of the centrifugal rotor.
  • the centrifugal of the invention incorporates a number of features which enable it to fulfill the separating function with maximum efficiency.
  • the Walls of the rotor are arranged at'a substantial angle with respect to the axis of the rotor in order tovfacilitate flow of deposited solids toward the orifices from which they are to be discharged.
  • the centrifugal rotor ⁇ is provided with superposed stratifying discs.
  • the means provided for actuating the valves are positive in their action, and delicately responsive to conditions within the rotor by which actuation of the valves is attained.
  • valves and their actuating floats could not be located in a longitudinally central zone of the rotor provided with stratifying discs, since the actuating means extended to the inner surface of the liquid under treatment. It was therefore necessary to locate the floats which controlled the actuation of the valves toward the base of the rotor, beneath the discs.
  • This object has been attained by providing valve actuating lmeans which are extremely compact and which are located in the part of the centrifugal rotor between the outer edges of the discs and the inner circumferential wall of the rotor.
  • These actuating means are positively operated by fluid pressure.
  • Another object of the invention has been to avoid contamination of discharged solids with discharged actuating liquid. This object is attained by providing a .construction in which there are separate outlets for the actuating liquid.
  • a still further object of the invention has been to provide a machine of this type. in which abrasion'of the parts against which the solids impinge upon discharge from the rotor is avoided.
  • Figure 1 is a central axial section through half of av centrifugal rotor embodying the principles -of the invention.

  • This liquid passes inwardly through the space between a dividing wall I9 toward the upper end of the rotor, and the upper portion 20 of the rotor, which may be secured to the main body of the rotor by the screw threaded connection 2 I.
  • This heavier constituent passes outwardly from the rotor across the ring dam 22.
  • the -lighter liquid passes inwardly through the spaces between the superposed discs I8 into a space 23 within the disc-block, and upwardly through the space'24 between a tubular extension 25 of the Idividing wall, and feed tube I5. 'I'he liquid centrifugal effluents discharged over ring dam 22 and from tube 25 are collected in separate centrifugal covers 6I and 62 (Fig. 6).
  • the inner peripheral wall of the main body of the rotor consists of opposed frusto-conical surfaces 26 and 21, and the point of maximum diameter of the main body of the rotor is located approximately centrally of this portion of the rotor.
  • the features ⁇ of the present invention pertain to the novel mechanism employed to effect intermittent discharge of the deposited solids, and are not dependent upon the particular features of feed of the mixture to the rotor or of discharge of the subsided liquid constituents separately from the rotor.
  • 'I'he present invention may be employed in connection with a centrifugal rotor of the so-called clarifler type, in which a solid constituent is separated from only a single liquid,
  • the rotor is provided with a plurality of small passages 29 through which these solids are intermittently discharged. These passages may be provided with bushings 30, radially extending valve guide members 3
  • a reciprocating valve 33 is provided for coaction with each of the valve seats 32,'and each of these valves 33 is connected with a valve stem 34, which is actuated by means to be described hereinafter for intermittent discharge of deposited solids through thevalve seats 32 and bushings'30.
  • valve stems 34 are. operated to break the contact between the valves 33 and valve seats 32 intermittently, in response to the accumulation of sludge in the space 28.
  • a plurality of iiuid pressure motors 35 fulfill this function, an lindividual motor being attached to each of the individual valve stems 34.
  • each of these motors comprises a housing which consists of an end portion 36 and a base portion 31 secured to the portion 36. This housing surrounds the moving parts of the motor.
  • the base portion 31 terminates in an annular extension 38 (see Fig. 2) which lies adjacent the zone 28 of accumulation of solids.
  • the inner end 39 of the valve stem 34 has a cover 4I which is the moving inember of the v4iiuid pressure motor.
  • the Amotor includes a Sylphon 40, having a portion secured to the inner end of the valve stem.
  • the inner end ofthe cover 4I of the valve stem has a cap 42 which reciprocates within a cylindrical bore 43 in the housing member 36 to assist in guiding the valve stem in its reciprocating movements.
  • An annular base member 44 is secured to the end of the Sylphon opposite to the cover 4I, and this base portion 44 is held against a iiange 45 of the skirt member 31.
  • a bracket 46 is secured to the housing base 31 and this bracket member is also secured to the rotor wall, thereby holding the iiuid pressure motor assembly in position.

  • 38 and 55 is connected with a bore 48, which is in turn connected with a conduit 49.

  • valve 33 In the operation of the machine described above, when the machine is rst brought up to speed, the valve 33 is forced against the valve seat. 32 under the inuence of the centrifugal force operative upon the 4valve stem 34 and the parts of the Sylphon. As the rotor fills with liquid, a part of this liquid enters the space'between the extension 38 and the v alve stem 34, and the pressure applied to this liquid by reason of the rotation of the main body of liquid within the rotor forces the valve stem 34 to move in- An inlet 41 in extensions bore.

  • valves 33 After the valves 33 are moved into closed position as discussed above, solids-accumulate within the space 2s during the continued feed of material to the rotor and rotation thereof, and these solids form a wall gradually approaches the extension 38 of the housing base portion 3l. As the accumulation of solids increases, the resistance to flow of liquid into the interior of the housing base portion 3l between the inner surface of the accumulated solids and the base 88 of the skirt also increases, until the flow resistance becomes suiiiciently great to offset the difference in hydrostatic balance between the inner edge of the ring dam 22 and the inner end of the bore 5l.

  • valve actuating unit within the space 28 which co pact, and may lie far beneath the surface of liquid in the centrifugal rotor.
  • a nest of discs extending substantially throughout the length -of the rotory may therefore be employed, and the valve lactuating mechanism may be located centrally of the longitudinal extent of the outer edge of the disc-block. Asaconsequence of this fact, a. rotor tapering in opposite directions toward the zone of solids discharge may be employed.
  • the rotor may have a substantial angle of conicity to facilitateflow of solids in opposite directions toward the solids discharge point without thenecessity of employing a rotor of such large maximum diameter at the zone of solids discharge as to impose the limitations discussed in the introductory remarks of the present application.
  • actuating motor.. for the valves have been illustrated as mounted with their axes in a radial plane with respect to the rotor, it will be understod that this radial mounting of the hydraulic motor is not an essential feature of the invention.
  • actuating means can be mounted with their axes inV any desired plane, provided suitable gear or lever actuating mechanism is provided for moving the valves to and from the valve seats.
  • the casing surrounding the centrifugal rotor includes covers 6i and 62 for receiving the liquid effluents from the rotor, and a lower cover 63, connected to a discharge chute 6d, lfor receiving the solids discharged through passages 29, and directing them to a suitable receptacle.
  • a feature of the present invention consists in the provision oi means for retarding the discharged solids before they impinge against any permanent part of the centrifugal frame.

  • a reciprocating piston 13 operates within the cylinder 1D, and this piston is in turn secured by means of piston rod 14 to the valves which control discharge'of deposited solids from the rotor, as illustrated and described in connection with Figures 1 to 3 of the drawings.
  • Liquid entering the cylinder 10 outwardly of the piston 13 causes that piston to move inwardly, and liquid passed to the portion of the housing 1l surrounding the cylinder and piston assembly causes it to move outwardly.
  • the accumulation ofsludge beneath the annular portion 15 operates to impede ingress of liquid into the connections 41 to 56, and thereby di- .minishes the pressure operative to hold the valves in closed position, thereby permitting the valves to be opened by the pressure imposed on the outer side of (beneath) the piston 13.
  • valves 33 In case one or more of the valves 33 becomes stuck in closed position, or in case it is found that the valves remain in closed position for a longer period than desired in the treatment of a particular material, the operator may cause these 'valves to be opened by interrupting feed of the i liquid to the machine until the level of liquid in the rotor recedes to a point-at which liquid no longer passes through bores 5I and channels 52 to channels 53 and conduitsl 54. This interruption of passage of liquid into the conduits 54 operates to cause the valves to open, in the same Way as does accumulation of solids adjacent to annular portion 3B of the skirt 31.
