Definitions

  • this invention relates to pumps adapted to supply spray generators and impellers such as are required in apparatus of the type mentioned above.
  • a spray generating cage is mounted on a vertical drive shaft having a driven connection at the top of the shaft and extending downwardly from bearings in its upper portion.
  • the rotatable spray generating cage consisting of a hub and a circularly arranged series of rods secured to end discs (or at the bottom a ring may be used instead of a disc), to form a barrel shaped cage with the lower end open.
  • the rods, or other cage elements are adapted to act as impact members for spattering drops of liquid into finer drops when the cage is rotated at high speed to impel the resulting droplets outward through the gas around the cage.
  • This barrelshaped impeller may be short or long depending upon the particular application, the diameter of the circle on which the impact elements are arranged and the speed at which it is to be rotated.
  • the new pump assembly of this invention can be attached directly to the lower part of the spray generating rotor or other rotary device for modifying the liquid, e.g., by filtering, mixing or spraying, and such spray device may be of the cage type with rods, etc., or a vane type, e.g., as in my prior co-pending application Ser. No. 80,822, filed January 5, 1961, now Patent No. 3,168,- 596.
  • a simple form of this new pump has direct attachment to the bottom of the spray generator or other rotor, requiring no separate drive nor separate driving connections.
  • the pump and cage can be independently driven, e.g., if different speeds are desired for the pump and cage respectively; or it can be geared down from the spraygenerating rotor, e.g., by planetary gearing to a fixed shaft telescoped inside the drive shaft; or by hydraulic coupling with an hydraulic torque converter or turbine liquid to be driven upward into the spray-generating device.
  • One may select from the variety of known vanes and vane arrangements according to the volume of liquid required to be displaced, the control required, and the speed of rotation desired. 8
  • FIGURE 1 is a diagrammatic axial section of an air washer embodying the present invention in a structure of the type set forth and claimed in the Patent No. 2,889,005;
  • FIGURE 2 is a view in axial section on an enlarged scale of a pump similar to that shown in the air washer of FIGURE 1;
  • FIGURE 3 is a view similar to FIGURE 2 but of a different design of pump
  • FIGURE 4 is a similar view of another pump embodying this invention.
  • FIGURE 5 is a similar view with a cylindrical pump consists of a reservoir, or tank 10, at the bottom of a housing 12 near the top of which are a series of spray eliminators 14.
  • a shaft 15 operates in a bearing 16 which is held rigidly centered with respect to the housing 12 by means of the spray-eliminators 14, and a second bearing 18 on the top of the housing.
  • Multiple pulleys 20 at the top of the shaft provide for a V-belt drive connection with a motor (not shown).
  • a blower 22 near the top of the shaft serves to suck air up through the housing and drive it out through the exit duct 24-.
  • a duct 26 provides for inlet of air, or
  • a rotating-cage spray generator 30 which is secured on the shaft 15.
  • a disc 32 At the top of the spray generatoris a disc 32 and at the bottom a ring 33, below which with its top edge close to the opening in the ring 33, is a pump bowl 34 secured on the end of the shaft so that it operates with at least its bottom immersed in the liquid in the tank 10.
  • impeller vanes 36 At least in the lower part of this pump bowl are impeller vanes 36; advantageously, these impeller vanes are sloped downward in the direction of rotation, e.g., in the example illustrated in FIGURE 1 of the drawings, 15.
  • the bowl itself is a surface of revolution, thus it may be truly bowl shaped, more or less hemispherical, cylindrical or a truncated conical form.
  • the length and the diameter are matters of design for individual installations and will be determined largely by the volume of flow which it is required to deliver and the rpm. which is considered desirable for operation.
  • the bowl flares outward in an upward direction so as to take advantage of centrifugal force in aid of, or in lieu of, the impeller action of the vanes. Such flaring should best begin below the normal liquid level.
  • the dimensions will be of the order of inches or a foot, or more; likewise, the height may vary from a few inches to three feet or more.
  • the pump may be conical, or other flaring surface of rotation, over its entire length or only for a short segment in which the pump bowl is immersed in liquid.
  • the vanes advantageously are positioned to extend to, and advantageously to be submerged in, the liquid in the reservoir.
  • the outward slope of the pump bowl from the intake opening may be selected at will, but ordinarily will vary from zero (for a cylindrical pump) to 60 from the axis of rotation, and will ordinarily be in the range'from 6 to 36 inches in length.
  • Vanes are not necessary to operations of the pump but do greatly enhance its effectiveness. Such vanes if used advantageously extend below the normal liquid level so that the pump does not require priming. They may be radial and parallel to the axis or they may be forwardly inclined, parallel to the axis or curved with respect to the direction of rotation. As there are wide variations in the applications for such pumps and the respective' speeds at which shafts to which they may be applied are necessarily rotated, it is an advantage of the present invention that it may be tailored to such varying requirements to give the desired Volume of flow.
  • the bowl 3412-d (shown in section) has at its top an annular flange 38 which is bolted to the bottom ring 33 of the spray generator cage to provide for driving the bowl in rotation.
  • FIGURE 2 an alternative is indicated in which the shaft 15a is extended and the vanes 36 extend inward at the bottom to form a spider 37 and likewise a spider is formed at the top, by which the cone is mounted on the bottom of the shaft 15a.
  • the slope of the sides of the cone is 20 to the axis, but this is not regarded as critical; other slopes may be used as indicated above.
  • the upper interior rim of the cone that is, the inner opening of the flange 38, substantially coincides with the central opening of the annular ring 33 at the bottom of the cage 30.
  • FIGURE 3 shows a bowl 34b approximating a hemispherical shape and with vanes 36b on its inside extending parallel to the axis and meeting at the bottom of the bowl.
  • FIGURE 4 shows still another variant in which the bowl 34c carrying the impeller vanes 360 is mounted on the bottom of the cage by means of the annular flange 38; and a stationary post 40 secured to the bottom of the tank 10 extends up into the center of the pump 34c and is provided with vanes 42 which have a narrow clearance from the moving vanes 36c.
  • These stationary vanes ordinarily vertically positioned, coact with, which may be sloping or spiral, vanes on the rotating cone to give an increased pumping action.
  • Non-clogging characteristics (6) Adaptability to a variety of apparatus where liquid is required to be pumped at relatively low pressure.
  • a gas washing apparatus comprising a housing having gas inlet means and gas outlet means, a gas washing zone within said housing between said inlet and said outlet, means for flowing a gas to be washed into said housing through said inlet, through said washing zone and out through said outlet, reservoir means in the base of said housing for containing a volume of a stantially flat disk and at their lower ends to an annular-fiat ring forming a liquid feed inlet mouth for said generator, said ring being in a plane at right angles to said impact surfaces, means for rotating said generator secured to said upper rotatable disk, and a hollow pump body of circular cross-section having an intake opening at its lower end and an output mouth at its upper end, means including an annular flange on said pump body for securing said upper end of said pump body to said annular-fiat ring for coaxial rotation therewith whereby said .pump body output mouth and said generator inlet mouth are in tight mouth-to-mouth relation, and said pump body intake extends below the washing liquid level in said
  • a gas washing apparatus as defined in claim 1 further comprising vane means extending upwardly within said reservoir and extending into said pump body to reduce eddy currents in said Washing liquid caused by rotation of said generator and .pump.
