Definitions

  • the present invention relates to a static fluid mixing pump device of the kind in which a fluid material is entrained within a transport fluid.
  • the transport fluid may be a gas, typically compressed air, or the transport fluid may be a liquid, for example water.
  • Ejectors and eductors and the like devices are well known in the art and are used in a plethora of applications involving the inducement of fluid flow through a conduit for various purposes including but not limited to the transport of fluid material from one point to another, the mixing of materials, or the treatment of the material, for example by maceration to effect particle size reduction.
  • Most devices of this kind involve the use of compressed gas, e.g. air, as the transport medium and a venturi arrangement in the transport system to accelerate flow and effectively to draw the fluid material within the relevant transport conduit.
  • Some systems merely employ parallel injection of the transport medium via a concentric sleeve around the conduit to induce or assist in establishing the required flow of material therewithin.
  • An advantage of the present invention is that the pump device has a simplified configuration of elements with absence of any moving parts, with transport fluid jets located downstream of a relative narrow portion of the fluid material tube.
  • the pump device is capable of usage in a wide range of applications ranging from deployment in simple aquaria in which aeration of water is required to industrial conveying plant for the transport of fluid materials, as well as in any angular inclination between and including vertical and horizontal orientations.
  • a static fluid mixing pump device including a narrow bore transport fluid inlet means, a fluid material tube having an inlet and an outlet for fluid material, the tube having a dimensionally increasing flared transition portion in a flow direction of the fluid material, and a plurality of jets in the vicinity of said transition portion, typically downstream of the tube inlet, and connected to the transport fluid inlet means.
  • a static fluid mixing pump device wherein the tube is a relatively outer hollow cylindrical tube having the inlet and the outlet for fluid material flow and the narrow bore transport fluid inlet means, the device including an inner generally hollow cylindrical liner for the tube sealably located coaxially therewithin, the liner having an inlet and an outlet registering with the inlet and the outlet of the tube respectively thus constituting a through passage from the inlet of the tube to the inlet of the liner and thence to the outlet of the liner and the outlet of the tube, a plenum chamber formed between the liner and the tube and communicating with the transport fluid inlet means, the liner having the flared portion defining the dimensionally increasing transition in the internal dimension of the liner in a direction from the inlet thereof towards the outlet thereof, and the plurality of fluid jets being defined in the wall of the liner and extending from the plenum to the inside of the liner.
  • the fluid jets may be in the form of nozzles or may be constructed of nozzles at the end of fluid passages provided with vanes appropriate for the purpose of inducing the requisite directional flow characteristics for the transport fluid.
  • the fluid jets may be tangentially orientated at the same level.
  • the fluid jets are tangentially orientated as aforesaid at a number of levels upstream of the transition, at the transition or downstream thereof or any combination.
  • the fluid jets are provided at one or more of the levels as indicated supra but are radially and angularly orientated in the direction from the inlet towards the outlet of the tube.
  • the liner of the second embodiment is sealably held within the tube by means for example of O-rings suitably seating in grooves provided for that purpose in the outer periphery of the liner at each end thereof.
  • Figure 1 is a perspective diagrammatic view of a first embodiment of a static fluid pump device in accordance with the present invention
  • Figure 2 is a longitudinal cross sectional view of a second embodiment in accordance with the present invention with one tangential orientation of jets;
  • Figure 3 is a top plan view of the liner of the embodiment of Figure 2;
  • Figure 4 is a view similar to Figure 3 of a liner with an alternative radial orientation of jets.
  • Figure 5 is a combined left-hand-side external view and right-hand-side cross- sectional view taken along line 5-5 of Figure 4.
  • a rectangular base 12 defines a mount for the pump 10 and includes two plates 14, 16 secured together by appropriate fixtures (not shown) extending through holes 18 provided for that purpose at or near the corners of the base.
  • a typically relative narrow bore compressed air inlet means 20, or transport fluid inlet port is provided in the relatively upper plate 14 (shown in dotted lines for clarity purposes) of the base 12 and communicates via one or more passages within the base, such as first and second annular plenums 24 in fluid communication with each other via a gap defined between the intermediate wall 24' and the upper plate 14, with a series of tangentially orientated fluid jets 22 provided circumferentially around an increasing dimensional transition 30 (a sharply increasing flared transition shown) in a fluid material transport tube 32.
  • the tube 32 is provided with an inlet 34 and is formed within the plates 14, 16 with a smaller diameter portion 33 being formed in and through the lower plate 16 and a larger diameter portion 35 formed in and through the upper plate 14 as illustrated in Figure 1 , providing an outlet 37.
  • This first embodiment may be deployed for example within an aquarium (not shown) for the purpose of water aeration and in this instance the pump device 10 would be suitably mounted in the aquarium in such manner that water access to the lower portion 33 of the tube 32 in plate 16 is assured.
  • a compressed air supply is piped (not shown) to the inlet 20 whence the air exhausts in a swirling motion from the jets 22 at the transition between the portion 33 and 35, water flow being induced through the inlet 34 then through the tube 32 from the smaller dimension portion 33 into the larger dimension portion 35 and thence through the outlet 37.
  • the air is thus mixed with the water to aerate the same and at the same time to provide the motive power for the flow through the pump 10.
  • a second embodiment of static fluid mixing pump device in accordance with the present invention is indicated generally at 100 and comprises a hollow cylindrical tube 102 having an inlet 103 and an outlet 104 at opposite ends thereof with an inlet port 106 for a compressed air supply.
  • a liner 108 is sealingly located within the tube 102 by means of O-rings (not shown) seating in grooves 110 at each end of the liner.
  • the external wall 112 of the liner 108 is so shaped as to define in combination with the inner wall of the tube 102 a plenum 114 communicating with the inlet port 106.
  • the inner wall 120 of the liner 108 is venturi-shaped with an inlet section 121 of reducing diameter leading to a throat section 122 ending with a dimensionally increasing transition portion 122' that extends into an outwardly flared outlet section 123.
  • a plurality of jets 130 is provided at different levels disposed circumferentially of the liner 108 and orientated substantially tangentially thereof, as shown by angle A in Figure 3. Some of the fluid jets 130 are located upstream of and adjacent the transition portion 122' in the throat section 122, some at the transition portion 122' and some downstream within the flared portion 123.
  • a compressed air supply is connected to the inlet port 106 of the tube
  • the transport fluid may be a liquid such as water.
  • outlet 104 of the tube 102 could be located much further away from the transition portion 122' and could be provided on a tube extension which could be flexible depending on the needs.
  • the diametrical ratio as between the outlet of the flared transition portion and the inlet thereof is variable dependent upon the specific application of the mixing pump.
  • the ratio may be 2:1.
  • the fluid material could be a liquid, a slurry of particulate materials in a liquid carrier, or purely flowable particulate material.
  • the transport fluid may be gaseous or in liquid form, for example compressed air or water respectively.
