Definitions

  • This invention relates generally to apparatus employed in the mixing of chemical concentrate with a diluting liquid. More particularly, it relates to an eductor for drawing chemical concentrate from a container and into the diluting liquid wherein the reduced pressure in the eductor can be easily adjusted.
  • One of the new backflow prevention methods is to use an elastomer in a critical path in such a manner that if a backsiphonage occurs, the elastomer will seal the path closed, thus preventing backflow.
  • the atmosphere of an enclosed water supply system lends itself well to Herschel-type venturi systems. Vacuum profiles are based on standard inlet lengths, diameters and cone angles, which are proportional to exit throat lengths, diameters and cone angles. To change a vacuum profile requires a redesign of the entire venturi.
  • the prior art does not provide a non-air gap eductor wherein the vacuum profile can be changed without redesigning the entire venturi.
  • the eductor of this invention which in one embodiment includes a body member providing a longitudinal axis.
  • a flow path extends longitudinally through the body member, the flow path defined by a first flow guide and a second flow guide, the second flow guide constructed and arranged to receive liquid from the first flow guide.
  • a closed back flow prevention member is operatively associated with the first flow guide.
  • a venturi tube is positioned in the flow path for receiving liquid from the second flow guide, the second flow guide and the venturi tube are connected by a passage portion. There is an opening in the passage, the opening is constructed and arranged to produce a desired vacuum in the venturi tube. At least one channel is provided laterally to the longitudinal axis for flowing a liquid concentrate into the venturi tube.
  • the flow path further includes a discharge passage extending from the venturi tube to the outside of the body member.
  • the channel includes a check valve and there are present two lateral channels.
  • the eductor in another embodiment includes a body member providing a longitudinal axis.
  • a flow path extends longitudinally through the body member, the flow path defined by a first flow guide and a second flow guide, the second flow guide constructed and arranged to receive liquid from the first flow guide.
  • a closed backflow prevention member is operatively associated with the first flow guide.
  • a venturi tube is positioned in the flow path for receiving liquid from the second flow guide, the second flow guide and the venturi tube are connected by a passage portion. There is an opening in the passage.
  • the second flow guide is defined by a tubular portion extending over the opening in the passage. At least one channel is provided laterally to the longitudinal axis for flowing a liquid concentrate into the venturi tube.
  • the flow path further including a discharge passage extending from the venturi tube to the outside of the body member. The extension of the tubular portion over the opening in the passage is designed to afford a desired vacuum profile.
  • the eductor includes a body member providing a longitudinal axis.
  • a flow path extends longitudinally through the body member, the flow path defined by a first flow guide and a second flow guide, the second flow guide constructed and arranged to receive liquid from the first flow guide.
  • a closed back flow prevention member is operatively associated with the first flow guide.
  • a venturi tube is positioned in the flow path for receiving liquid from the second flow guide, the first flow guide and the second flow guide positioned in a spaced relationship so as to divert some of the liquid from the venturi tube to produce a desired vacuum in the venturi tube. At least one channel lateral to the longitudinal axis for flowing a liquid concentrate into the venturi tube.
  • the flow path further including a discharge passage extending from the venturi tube to the outside of the body member.
  • the second flow guide and the tubular portion are in the form of a funnel member.

  • FIG. 9 is a view similar to FIG. 8 with the embodiment turned 45 degrees.
  • FIG. 10 is a view similar to FIG. 9 showing another embodiment of the invention.
  • FIG. 1 there is shown a schematic diagram for a type of dispensing equipment generally in which the eductor 10 of the invention is employed.
  • the equipment 11 has an enclosure 13 and containers 15 in the enclosure 13 or, possibly, outside the enclosure 13 but connected as shown by lines 19 .
  • each container 15 is filled with a different liquid 17 a and 17 b .
  • it is desirable to have two containers 15 filled with the same liquid 17 there may be occasions where it is desirable to have two containers 15 filled with the same liquid 17 .
  • the inlet line 21 of the equipment 11 is connected to a source of water feeding a header 23 .
  • Branch pipes 25 are connected to the header 23 and each branch pipe 25 includes a valve 27 “dedicated” to that pipe 25 .
  • a particular valve 27 When a particular valve 27 is actuated, water flows through the related eductor 10 and mixes a concentrated liquid 17 with such water to form a dilute solution. Each mixed dilute solution is dispensed through a separate tube 29 .
  • the amount of concentrate introduced to the eductor 10 can be controlled by the valves 32 .
  • the eductor 10 includes a generally tubular body 33 with two opposing ribs 43 and 44 . It has an inlet end 35 and an outlet section 37 , the latter having an outlet fitting 39 attached thereto. Such fitting 39 has a necked-down portion 41 for connection to outlet tube 29 .
  • the inlet section 35 of eductor 10 includes a core structure 48 with a barrel 50 surrounded by the ribs 52 .
  • An outer casing 58 surrounds the resilient sleeve and has the vents 60 .
  • An outlet passage 61 communicates with a funnel member 64 or first flow guide seated in the conical section 63 .
  • a seal 66 is positioned between the outer casing 58 and the conical section 63 .
  • a second flow guide 67 is connected to the first flow guide 64 and the second flow guide 67 is connected to venturi tube 65 by a passage portion 69 provided by the funnel portion 80 of the first flow guide 64 , the conical section 63 , and the second flow guide 67 .
  • An opening 70 is provided in the passage portion 69 of the second flow guide 67 .
  • Inlet section 35 is interconnected to the tubular body 33 by the connecting portion 62 . It includes input connections 72 and 73 communicating with channels 75 and 76 which in turn communicate with passage 78 .
  • a check valve assembly, 74 preferably of the ball check type, is connected to input connection 73 . It will be seen in FIG. 3 that check valve assembly 74 is shown on an opposing side from that shown in FIG. 2 . Also, input connection 72 is shown.
  • FIGS. 4, 8 , 9 and 10 include many of the same components as described in FIG. 3 , with similar numbers referring to similar components except with an “A”, “B” or “C” suffix.
  • One of the differences between embodiment 10 and embodiments 10 A, 10 B and 10 C is that in embodiments 10 A, 10 B and 10 C they do not include the funnel member 64 .
  • embodiment 10 shows the positioning of funnel stem 80 of funnel member 64 over a portion of the opening 70 . The purpose of this is explained in the Operation to follow.
  • eductor 10 B differs from eductor 10 A in the configuration and connection between the first flow guide 64 B and the second flow guide 67 B. Other differences are the one piece molding of outer casing 58 B with ribs 43 B and 44 A and the additional connecting portion 62 B between the inlet section 35 B and venturi section 36 B.
  • eductor 10 C differs from the other eductors 10 , 10 A and 10 B in that there is no window in the second flow guide 67 C. Instead the first flow guide 64 C is spaced from the second flow guide 67 C. This provides a diversion of water away from venturi tube 65 C.
  • eductors 10 , 10 A, 10 B and 10 C will be connected into the dispensing equipment 11 as previously described in conjunction with FIG. 1 .
  • venturi tube 65 As the water passes into venturi tube 65 it creates a reduction in pressure sufficient to open ball check valve assembly 74 and draw a chemical concentrated from a container 15 into inlet connection 73 and into channel 76 . From channel 76 it is mixed with water flowing through passage 78 . The combined solution of water and concentrate exits through outlet fitting 39 and outlet tube 29 providing a discharge passage as seen in FIG. 1 .
  • ball check valve assembly 74 serves as a primer for the vacuum in passage 76 and keep prime on the container 15 . It also prevents pressurized water from source to contaminate concentrate to chemical from inlet 73 .
  • eductor 10 An important aspect of eductor 10 is the positioning of funnel portion 80 in conjunction with opening 70 . This controls the amount of water flowing through the venturi tube 65 and accordingly, the amount of negative pressure created therein. It will be appreciated that the greater the extension of the funnel stem over the opening 70 , the greater the volume of water will flow into the venturi tube 65 , and the greater the negative pressure. Diverted water passes through the opening 70 and forms a secondary stream which passes into the chamber 68 and subsequently into outlet port 71 , whereafter it is combined with the stream of water and chemical concentrate exiting from passage 78 . This concentric flow of the secondary stream and the primary stream through the venturi tube 65 is illustrated in U.S. Pat. No. 5,927,338. It is also described in conjunction with eductor 10 B in FIG. 9 .
  • Eductors 10 A and 10 B function in substantially the same manner as described for eductor 10 .
  • the openings 70 A and 70 B are designed with specific dimensions to direct a predetermined amount of water away from the venturi tubes 65 A and 65 B and thus effect a desired vacuum.
  • FIG. 9 is presented to show the secondary stream which forms as a result of water being diverted from the venturi tube 65 B. The stream will flow outwardly into chamber 68 B and follow the path shown by the arrows until it exits into hose 82 B. At the same time chemical concentrate diluted by the water passing through venturi tube 65 B will exit in tube 83 B. As stated previously, this flow of a primary and a secondary stream of water and diluted chemical concentrate and a secondary stream of water is described in U.S. Pat. No. 5,927,338.
  • the eductor 10 C shown in FIG. 10 operates without a window. It relies on the spacing of first flow guide 64 C from the second flow guide 67 C to diver water away from the venturi tube 65 C and thereby create the desired vacuum effect. This is a unique feature as it has never been done before in conjunction with a non-air gap eductor.
  • the siphon-breaking air gap provided by barrel 50 and resilient sleeve 56 operates in the manner described in the previously referred to PCT Application No. PCT/US03/08428.
  • As water flows through fluid outlets 54 it will expand sleeve 56 and water will flow between the sleeve and barrel 50 into funnel member 64 and ultimately to venturi tube 65 .
  • the resilient sleeve 56 contracts and fits lightly around the barrel 50 to prevent any reverse flow of water. If a siphon action occurs in the water lines 21 and 25 , such as when there is a sudden drop in pressure of the main water supply, the resilient sleeve 56 is already sealed against the barrel 50 , as already discussed. Fluid instead passes into the space between the sleeve 56 and the outer casing 58 and exits through the vents 60 .
  • the eductors 10 and 10 A have been shown with two inlet ports or connections 72 and 73 . If desired, only one could be used as shown in conjunction with eductor 10 B. In that instance, the other would be plugged. Alternatively, the inlet connections can be connected to two containers 15 each with the same liquid chemical concentrate or, alternatively, with different chemical concentrate. Ribs 43 A, 44 A and inlet section 35 A are shown as one piece and outer casing 58 as another. If desired, these could be molded from a suitable plastic material as one piece as indicated in FIGS. 8, 9 and 10 . Other variations and modifications of this invention will be obvious to those skilled in the art. This invention is not to be limited except as set forth in the following claims.
