No. 2 (Patent Document 2).
However, the methods described in Patent Documents 1 and 2 have a problem that the amount of decrease in the amount of electrolyte after chemical conversion is large because mist is forcibly sucked.
Therefore, the inventor of the present application made a prototype of a mist guide / hose coupling cylinder 1 as shown in FIG. 7, and tried to suck the mist by interposing it between the liquid injection port and the suction hose.
The mist guide / hose coupling cylinder 1 shown in FIG. 7 will be described in detail below.
The cylinder A is a synthetic resin molded body. A through cylinder 1a is formed in the center of the lower surface thereof, and communication holes 1b, 1b,... The cylindrical space 1c is opened in the upper surface of the body 1, and the inner peripheral surface of the upper cylindrical wall surrounding the cylindrical space 1c is provided with a thread 1d.
Thus, the cylindrical body 1 is the upper surface of the cylindrical liquid injection port C provided at the center of the exhaust pipe B formed in the lid A of the control valve type storage battery when the battery is formed or initially charged. Then, the center through cylinder 1a is placed in alignment with the liquid injection port C. At this time, the outer peripheral surface of the lower end of the cylindrical body 1 protrudes upward from the upper surface of the lid A, and the exhaust plug provided on the lower inner peripheral surface of the peripheral wall b1 of the exhaust cylinder B surrounding the outer periphery of the liquid injection port C Is fitted into a screw tube portion b2 for screwing, and the tube body 1 is held in an upright state.
Thus, in the mist suction, as shown in the drawing, a suction hose D led out from the mist suction device into the cylindrical space 1c in the upper cylindrical wall of the cylindrical body 1 is made of a synthetic resin made by connecting the tip thereof with a connector E. The connecting tube F is screwed to the inner periphery of the upper tube wall by the thread f applied to the outer peripheral surface thereof, and connected to the tube 1 and the suction device is started in this state, thereby charging the battery. The mist generated at the end of is passed through the injection port C through the passage cylinder 1a aligned therewith and is sucked by the suction hose D. At this time, the mist leaking from the gap between the lower end of the cylindrical body 1 and the upper end of the cylindrical liquid injection port C flows into the four vent holes 1b, 1b,.
In this way, since the cylindrical body 1 holds the suction hose D firmly, a stable and satisfactory suction operation can be performed without anxiety. Further, in order to prevent the cylinder 1 in the upright state from being shaken in the lateral direction, a synthetic resin pipe G for locking is inserted into the through-cylinder 1a, and the lower end thereof is inserted into the liquid injection port C. Facing the inside of the battery. In this way, by inserting the pipe G having a diameter smaller than the diameter of the liquid injection port C into the liquid injection port C, the left and right movement of the cylindrical body 1 can be prevented and a stable state can be set.

Embodiments of the present invention will be described with reference to the accompanying drawings.
1, 10 is a perspective view of an adapter according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line II-II in FIG. The adapter 10 is made of a synthetic resin molded body, and is used when the battery is transported to a battery case formation or initial charging process by a forklift or a conveyor after completion of the liquid injection work, Used during mist suction in the initial charging process.

  The adapter 10 is formed of a cylindrical body, and at least a lower part thereof has an outer diameter suitable for being installed in an exhaust pipe projecting from a liquid injection port on the upper surface of a storage battery lid, and a lower part of the cylindrical body includes: A splash-proof reflux mechanism 11 is provided. Further, the upper part of the cylinder body is formed with an open upper receiving space 12 for inserting the mist guide / hose connection cylinder body 1 shown in FIG. 5, and a plurality of notches 13 are shown at the lower end thereof. In this example, two are disposed at opposing positions on the circumference of the cylinder. Preferably, each notch 13 forms a free piece 14, and the lower edge of the free piece is formed with a protrusion 14a protruding outward. In addition, two annular protrusions 15 having rounded tips are arranged on the lower outer peripheral surface of the cylindrical body.

The splash-proof reflux mechanism 11 extends in the horizontal direction between the core 11a and the cylinder wall so as to form a spiral exhaust passage centering on the core 11a extending on the central axis of the cylinder and vertically And a partition plate 11b that partitions the space in a spiral manner.
In the middle part of the cylindrical body of the adapter 10, a horizontal partition plate 17 having a communication hole 16 formed in the center is formed above the splash-proof reflux mechanism 11, and the partition plate 17 The bottom surface of the receiving space 12 is formed.

Further, the lower surface of the partition plate 17 is formed on an inclined surface 17a that is inclined downward from the inside to the outside. On the upper surface of the partition plate 17, on the outer peripheral surface thereof, three triangular projecting plates 18 having an inclined surface 18a inclined downward toward the center of the upper end surface are arranged at regular intervals in the circumferential direction. .
Further, at the upper part of the cylindrical body, at the upper end portion of the inner peripheral surface of the receiving space 12, vertical ribs 19 for guiding the cylindrical body 1 when inserted into the receiving space 12 are equidistantly arranged on the circumference. Three strips are formed, and the lower ends of the three strips are connected to the three triangular protruding plates 18.

  The adapter 10 having the above-described configuration is shown in FIG. 3 when transporting the electrolytic solution to the storage battery after the injection to the chemical conversion process, and further when transporting to the initial charging process after the chemical conversion. The adapter 10 is mounted on the exhaust cylinder B of the storage battery lid A, and the upper and outer circumferences of the liquid injection cylinder C located at the center of the exhaust cylinder B are encapsulated by the cylinder of the adapter 10. In this state, each battery is transported to the next process, for example, a pallet on which a predetermined number of batteries are mounted is lifted and transported by a forklift, for example. Thus, the electrolytic solution of the storage battery is prevented from scattering from the injection port to the outside.

  The adapter 10 is also used by being attached to the exhaust tube B of the lid A of the storage battery as shown in FIG. 4 when performing mist suction in the battery case forming process and the initial charging process. In this mounting, the two annular protrusions 15 on the outer periphery of the lower part of the cylindrical body of the adapter 10 abut against the inner surface of the peripheral wall of the exhaust cylinder B, and thus act to keep the adapter 10 in an upright state stably. In addition, the free piece 14 in each of the left and right cutouts 13 at the lower end of the adapter 10 has a projection 14a engaged with the threaded portion b2 on the inner periphery of the exhaust tube B, so that the upright state of the adapter 10 can be stabilized. While maintaining, it bends inwardly to the protrusion and has the effect of increasing the notch space.

Further, the adapter 10 is loaded with the mist guide / hose connecting cylinder 1 in the upper receiving space 12. At the time of this insertion, the three downwardly inclined surfaces 18a, 18a, 18a disposed on the bottom surface of the receiving space 12 are centered on the cylindrical body 1 to be inserted.

You may insert a cylinder.
With this absorption action, a gas mixture such as water vapor and acid mist rises from the liquid injection port C together with the gas generated particularly at the end of charging, and flows into the adapter 10. In the process of ascending the passage, the acid mist (mist) hits and collides with the spiral partition plate 11b and the annular partition plate 17 thereabove, and the collected electrolyte is the inclined surface 17a of the annular partition plate 17. And then flows down along the core 11a and flows back into the battery. The gas that has passed through the communication hole 16 in the center of the annular partition plate 17 flows into the clearance 20 above it, and the mist that collides with the bottom surface of the cylinder 1 above is collected and diffused. The electrolyte solution thus refluxed through the communication hole 16. On the other hand, the mist guide / hose connecting cylinder 1 flows into the center through cylinder 1a and the outer communication holes 1b, 1b,... And is sucked into the suction hose D through the connecting cylinder F. Also, by this suction action, outside air flows into the splash-proof reflux mechanism 11 of the adapter 10 through the notches 13 and 13 provided at the lower end of the cylinder of the adapter 10, and rises from the liquid injection port C. Join and collect mist. Thus, it goes without saying that the manufacture of the control valve type lead-acid battery is finished by finally attaching a rubber valve to the injection port C and screwing the exhaust plug into the exhaust cylinder B.

  As shown in FIG. 4, using the assembly of the present invention, each of the electrolytes in the case of actually performing mist suction during battery case formation on 30 control valve type lead storage batteries of 200 Ah-2V in the same manner Using the mist guide and hose connection cylinder 1 that is the prototype shown in FIG. 5 for 30 of the above storage batteries of the same type with the liquid reduction amount, similarly, when mist suction is performed 30 times during battery case formation The amount of liquid reduction of each electrolyte solution was measured. The measurement results were as shown in Table 1 and Table 2, respectively.
