Definitions

  • This invention relates generally to liquid filling apparatus and, more specifically, to apparatus for filling a storage battery with a liquid electrolyte.
  • a typical prior art device for filling a storage battery with electrolyte comprised a pair of coaxial tubes, one located internal to the other.
  • the electrolyte was supplied to the centrally located tube and a vacuum was applied to the annular discharge passage located between the inside of the outer tube and the outside of the inner tube.
  • the vacuum in the annular discharge passage would draw off excess electrolyte when the level of the electrolyte in the container reached the lower end of the annular discharge passage.
  • These devices are necessarily constructed in a coaxial relation because with this arrangement they are readily adaptable to fit through the circular openings in the top of a battery container. Normally, these openings are kept as small as possible to avoid sealing problems and loss of liquid through the battery cover.
  • an improved filling device comprising a first annular inlet passage for introducing a' liquid into a container and a second cylindrical discharge passage for discharging excess liquid in the container-However, reversing the filling and discharge passages is not sufficient to produce a good liquid level filling apparatus.
  • a groove along the side of the radially extending ridge that prevents dripping of liquid from the tubes when the filling unit is raised.
  • This groove allows any excess liquid that is clinging to the tubes to run down the tube and along the groove and be drawn into the discharge passage as the filling unit is removed from the container.
  • the filling unit is supplying a corrosive liquid electrolyte which obviously would damage noncorrosive resistant material located next to the filling head.
  • An additional advantage of this type of reversed filling head is that the cylindrical outlet creates a larger diameter opening for the crud and foreign material that is drawn off of the container than an annular passage of the same area.
  • the invention comprises a first member having an annular inlet passage located in fluid communication with a reservoir for supplying a liquid to a container and a cylindrical member located coaxially within the first member for drawing off liquid when the level of the liquid in the container reaches the lower end of the cylindrical member.
  • the cylindrical member includes a radially extending ridge located on the lower end for deflecting the incoming fluid radially outward so as to prevent entrainment of fluid by the centrally located discharge tube.
  • FIG. 1 is a pictorial end view of the end of the liquid filling unit
  • FIG. 2 is a cross-sectional view of the acid filling head assembly located in a container
  • FIG. 3 is a pictorial front view of the filling head assembly for use in filling a number of cells of a battery.
  • reference numeral 10 generally denotes our filling unit comprising a first cylindrical member 11 and a second cylindrical member 12. Cylindrical member 11 and cylindrical member 12 are Io'cated'ooaxially along axis 14 so as to create an annular inlet passage 13 between the outside of cylindrical member 12 and the inside of cylindrical member 11. Located within cylindrical member 12 is a circular outlet passage 15 for discharging excess liquid. The bottom of cylindrical member 11 is located above the bottom of cylindrical member 12 so as not to direct fluid immediately adjacent outlet passage 15. Located at the bottom of cylindrical member 12 is a radially extending ridge l6. Ridge 16 extendsat an angle of approximately from axis 14 and forms a portion of cylindrical member 12. Ridge 16 directs fluid flowing from inlet passage 13 radially away from. cylindrical member 12. Although ridge 16 extends at an angle of l05 from axis 14, this is by way of illustration and should not be intended as a limitation.
  • a groove 17 that extends completely through ridge l6 and is flush with the outside of cylindrical member 12.
  • cylindrical member 12 When filling unit 10 is in operation cylindrical member 12 is in a vertical position so that fluid flows vertically downward from inlet passage 13 along cylindrical member 12. When the supply of liquid to filling unit 10 is shut off liquid may cling or adhere to ridge 16 outside of cylindrical member 12. Groove 17 allows this excess liquid to flow downward through groove 17 and be sucked into circular outlet 15 inside of cylindrical member 12.
  • cylindrical members 1 l and 12 would be made from a material that is noncorrosive such as polyvinyl chloride.
  • Typical dimensions used in this type of filling unit are as follows: cylindrical member 11 outside diameter .50 inch; cylindrical member 11 inside diameter .36 inch; cylindrical member 12 outside diameter .31 inches; and cylindrical member 12 inside diameter .21 inches.
  • the outside diameter of ridge 16 is .50 inches so as to extend outward and deflect fluid flowing from inlet passage 13 radially outward.
  • Reference numeral 20 generally denotes a liquid filling head assembly for filling a liquid to a desired level in a container.
  • Liquid filling head assembly 20 comprises a housing 21 having a connector 22 that is adapted to be connected to a low pressure source and reservoir (not shown) and a connector 23 which is adapted to be connected to a reservoir of liquid (not shown) that is to supply liquid to a container.
  • Located on housing 21 is a dovetail member 24 for fastening the housing 21 to some suitable means for raising and lowering the unit.
  • Liquid filling head assembly 20 is shown supplying liquid to a container 25 having a circular opening 26 located therein.
  • the top edges of circular opening 26 engage a rubber cushion 27 so as to prevent splattering of liquid from container 25 past the edges of opening 26.
  • liquid is supplied to the inside of the container 25 from a source of liquid through hose connection 23, a reservoir 31 and an annular filling inlet passage 13 located between cylindrical member 11 and cylindrical member 12.
  • the liquid flows vertically downward along cylindrical member 12 and is deflected outward by ridge 16 as indicated by arrows.
  • a vacuum pump (not shown) is connected to connection 22 so as to produce low vacuum in circular outlet 15 in cylindrical member 12 through a passage 29 (partially hidden) and a passage 30.
  • Head assembly 20 comprises first filling unit 40, a second filling unit 41, a third filling unit 43, a fourth filling unit 44, a fifth filling unit 45 and a sixth filling unit 46.
  • Filling units 41 through 46 are identical to previously described filling unit and so will not be described in detail. These filling units are located in a spaced apart relationship so that entire head assembly 20 can be lowered with filling units 40, 41, 43, 44, 45 and 46 so as to place the filling units in a filling position within a container. Typical use in apparatus of this type would be to fill the adjacent cells on a multicell storage battery.
  • An electrolyte liquid level filling apparatus for batteries comprising a member containing a reservoir for a liquid, a first cylindrical member having a cylindrical passage located in fluid communication with said reservoir for supplying the liquid to a container located in an ambient atmosphere under a pressure P and a second cylindrical member having a cylindrical passage located therein, said second member located coaxially within said first member so as to form an annular inlet passage, said second member having one end adapted to be connected to a return reservoir located in an ambient atmosphere under a pressure P., the pressure P, characterized by being less than the pressure P so as to produce a suction at the other end of said passage thereby drawing fluid into said passage when the level of the liquid in the container approaches said other end, said other end of said second member having a radially outward extending circumferential portion located therefrom for deflecting the liquid from said first member radially outward thereby preventing entrainment of the liquid by said second member as it flows therepast.
  • said radially extending portion includes a groove so that when said member is removed from said container said groove allows liquid located on the top portion of said radially extending portion to be sucked into said outlet passage in said second cylindrical member.
  • the apparatus of claim 4 including at least two liquid leveling filling apparatus for supplying electrolyte to the individual cells of a battery.
  • the apparatus of claim 4 including a sponge material located around said first member so as to engage the top portion of the container in a fluid sealing relation thereby pr venting the liquid from splashing out of the container.
