The check ball 370 described later is built in the relief surface 314 and seals or opens the through hole 313 in conjunction with the upward and downward movement of the piston 310. [

A trapezoidal groove having an inclined surface 311 is formed on the outer periphery of the piston 310 and a concave groove 312 is formed on the bottom surface of the trapezoidal groove.

As to the function and operation of the piston 310,

When the piston 310 descends downward from the inside of the cylinder 320 by the driving means connected to the piston shaft 340, the check ball 370 provided inside the deflecting surface 314 is urged by the spring force of the spring 380 A negative pressure is generated in the cylinder 320 on the upper side of the piston 310 so that the electrolyte flows from the inlet 321 to the cylinder 320. As a result,

When the piston 310 is lifted upward, a pressure is generated in the upper cylinder 320 of the piston 310. The check ball 370 is lowered by the pressure to open the through hole 313, The electrolytic solution passes through the through hole 313 and flows into the lower side of the cylinder 320.

When the piston 310 descends again, the check ball 370 is brought into close contact with the through hole 313 to be sealed, so that a pressure is generated in the lower cylinder 320 of the piston 310 to allow the electrolyte to flow into the battery A negative pressure is generated in the upper cylinder 320 of the piston 310 so that the electrolyte flows back into the cylinder 320 so that the electrolytic solution can be supplied to the battery by the reciprocating movement of the piston 310.

The piston shaft 340 is integrally formed with a disk-shaped fixing plate 342 and a bolt 341 passing through the fixing plate 342 is screwed onto the upper surface of the piston 310.

The piston shaft 340 is connected to driving means (not shown) such as a hydraulic cylinder and functions to move the piston 310 connected to the piston shaft 340 up and down while moving up and down .

The sealing member 350 is inserted into a trapezoidal groove having an inclined surface 311 formed on the outer periphery of the piston 310. And functions to seal between the piston 310 and the cylinder 320.

Fig. 4A is a state before operation of the sealing member of the present invention, and Fig. 4B is a state after the sealing member of the present invention is in operation.

As shown in the figure, the sealing member 350 has a substantially elliptical outer shape in cross section and is inserted in a groove of a trapezoidal shape. A balance groove 351 is formed on the upper surface of the sealing member 350 and a protrusion 352 is formed on the lower surface of the piston 350. The recess 310 is formed on the bottom surface of the trapezoidal groove formed on the outer circumference of the piston 310 Is formed in the corresponding portion.

The sealing member 350 has an arc-shaped structure with the center protruding on both sides and a bent portion 353a formed on both sides of the sealing member 350. The reinforcing member 353 having elasticity is inserted.

As for the function and operation of the sealing member 350,

When the piston 310 is slidably fitted into the cylinder 320, the sealing material 350 is elastically deformed by the pressure in the concave groove 312 provided on the bottom surface of the trapezoidal groove formed on the outer peripheral surface of the piston 310. [ The projection 352 is filled and fixed to the concave groove 312 by the pressure at the time of the elastic deformation so that the center portion of the sealing material 350 is fixed to the concave groove 312 The sealing member 350 is interlocked with the balance groove 351 formed on the upper surface of the sealing member 350 so that the sealing member 350 is uniformly elastically deformed on both sides of the trapezoidal groove while fixing the sealing member 350, It has the function to raise the effect.

The reinforcing member 353 inserted in the sealing member 350 has an arcuate shape and is elastically juxtaposed in a substantially flat shape due to the pressure of the sealing member 350. By the elastic restoring force of the reinforcing member 353, Since the sealing member 350 presses the inner surface of the cylinder 320, the sealing member 350 has a function of reinforcing the sealing member 350 while the sealing effect is further increased.

The reinforcing member 353 has bent portions 353a and the bent portions 353a are rounded so that the end portions of the reinforcing members 353 break the sealing member 350 .

Hereinafter, the material of the sealing member 350 will be described.

Since the sealing material 350 is in contact with the electrolytic solution, it is likely to be corroded by sulfuric acid, which is a component of the electrolytic solution. If the sealing material 350 is corroded, the sealing effect is deteriorated. In this embodiment, Thereby minimizing corrosion.

The material of the sealing material 350 is 25 to 40 parts by weight of a fatty acid amide compound as a water repellent agent, 40 to 80 parts by weight of carbon black, 0.01 to 3 parts by weight of cobalt, 0.01 to 3 parts by weight of a quinone-imine antioxidant, 10 parts by weight of a rubber composition.

Such a rubber composition has improved heat and aging resistance, can prevent degradation of rubber, has an effect of reinforcing, and has a function of acid resistance. By adopting the rubber composition that minimizes corrosion and aging of the sealing material 350 as a material of the sealing material 350, the cylinder 320 and the piston 310 coupled to each other through the sealing material 350 are sealed It is possible to continuously maintain the effect of the present invention.

Referring again to FIG. 3,

The support plate 360 is tightly coupled to the step formed at the lower end of the relief surface 314 of the piston 310. The support plate 360 is formed with a through hole 361 passing through the upper and lower surfaces, To be able to flow in and out.

The check ball 370 is embedded in the resilient surface 314 of the piston 310 and is connected to the support plate 360 through the spring 380. The check ball 370 is in communication with the upward and downward movement of the piston 310, Thereby sealing or opening the hole 313.

The piston 310, the cylinder 320, the injection port 330, the piston shaft 340, and the support plate 360 constituting the above-described electrolyte supply unit are in contact with the electrolytic solution, so that they may be corroded by sulfuric acid, which is an electrolyte component.

In this embodiment, the material of the above configuration will be described.

This embodiment discloses a metal alloy composition excellent in acid resistance, corrosion resistance, and strength.

The alloy composition of the present embodiment

5.0 parts by weight of manganese, 0.09 parts by weight of silicon, 0.08 parts by weight of nickel, 10 parts by weight of tin and 1 part by weight of zirconium relative to 100 parts by weight of copper.

Such an alloy composition has properties of a high-strength alloy while having excellent corrosion resistance and corrosion resistance against a material having a high acidity.

That is, zirconium (Zr) having a function of making the structure finer and capable of forming a compound having excellent corrosion resistance in the electrolyte is added, and nickel and manganese are added to improve the solid solution strengthening effect and tin addition, And the zirconium has a crystal structure that is finely controlled so that the electrolyte has properties of an alloy excellent in corrosion resistance.

5 is a cross-sectional view of the filter.

As shown in the figure, the filter 400 is divided into a wind roller 410, a rewind roller 420, a guide roller 430, a filter net 440, a pressure sensor 450, and a filter 460.

When the filter 460 is wound around the wind roller 410 and the rewind roller 420 and the filter 460 is blocked by the impurities contained in the electrolyte in the filtration process and the function of filtering is lost, the rewind roller 420 The filter 460 is loosened from the wind roller 410 by rotating the filter 460 and the new filter 460 is mounted on one side of the filter net 440. This facilitates the exchange of the filters, Function.

The guide roller 430 functions to apply a tension while guiding the filter 460 wound around the wind roller 410 and the rewinding roller 420.

The filter net 440 is made of a metal of an acid-resistant material and has a filter hole 441 formed therein to support the filter 460 while allowing the electrolyte to pass therethrough.

The pressure sensor 450 is installed in the inflow chamber 470 in front of the filter net 440, that is, on the inner surface of the filter 400 on the side where the electrolyte comes in.

As to the function and operation of the filter 400,

If impurities accumulate in the filter 460 and the filtering function is deteriorated, the pressure in the filter inflow chamber 470 becomes high. When the pressure becomes higher and becomes higher than the set value, the controller (not shown) judges that the filter 460 is filled with impurities and the filtering function is lost, and the rewinding roller 420 is rotated by a drive means And the filter 460 formed on one side of the filter net 440 is replaced with a new filter 460 so that the filtering function is continuously maintained.

6A and 6B show another embodiment of the sealing material.

Here, the description of the same constitution as that of the sealing material described earlier will be omitted, and only the constituent features of this embodiment will be described.

As shown in FIG. 6A, the sealing material 350 is further provided with blade pieces 354 on both sides thereof, and the blade piece 354 is provided with an extension bending portion 355 at an end thereof.

As for the function and operation of the sealing member 350,

When the piston 310 is inserted into the cylinder 320, the blade piece 354 formed on the side surface of the sealing material 350 comes into contact with the side surface of the trapezoidal groove and is folded. At the end of the blade piece 354, Since the portion 355 is formed, the extension bending portion 355 is relatively thicker than the other portion.

Therefore, the expansion bending portion 355 is elastically deformed in the process of being inserted and is brought into close contact with the inclined surface 311 of the trapezoidal groove, so that the sealing effect remarkably increases.

As shown in the figure, a honeycomb-shaped suction port 356 protrudes on the surface of the sealing material 350 of FIG. 6B.

The suction port 356 has a honeycomb structure in which a groove 357 and a protrusion 358 are continuously formed and the protrusion 358 is made of an elastic material so that the suction port 356 is connected to the cylinder 320 so as to prevent the electrolyte from intruding.

That is, the groove 357 and the protrusion 358 serve as a vacuum adsorption function. By the protrusion 358 of the suction port 356, when the sealing material 350 contacts the inner wall of the cylinder 320, The sealing material 350 is attracted to the inner wall of the cylinder 320 or the piston 310 because the air in the space of the formed groove 357 is pushed out of the sealing material 350 and the relative vacuum portion in which the pressure is lowered, So that the sealing force is increased and the sealing effect is remarkably increased.

7 is a sectional view of a reservoir tank provided with a safety device.

The electrolytic solution in the reservoir tank may generate steam due to evaporation or chemical reaction, resulting in a rise in pressure, causing problems such as explosion of the reservoir tank. In this embodiment, the safety device installed in the pressure reservoir tank Will be described.

The safety device 600 formed on the upper surface of the reservoir tank 500 includes a disk 610, a guide rod 620, a spring 630, a discharge pipe 650, a venturi pipe 660, And a water tank 680, respectively.

The discharge pipe 650 penetrates the upper surface of the reservoir tank 600 and functions to discharge the steam formed in the reservoir tank 500.

A sheet 651 protrudes from the inner surface of the discharge pipe 650 to selectively open and close the discharge pipe 650 by a disk 610 described later.

The guide rod 620 is fixed to the inside of the discharge pipe 650 by bolts 640 and has a cylindrical shape and is slidably coupled to a disk 610 to be described later.

The disk 610 has a disk shape and is slidably engaged with the lower end of the guide rod 620 and is provided on the upper surface of the sheet 651.

The spring 630 is engaged with the upper end of the guide rod 620 and the upper surface of the disk 610 and is elastically deformed in conjunction with the pressure of the reservoir tank 500.

The venturi pipe 660 is formed so as to pass through the side surface of the discharge pipe 650 so that the steam discharged through the discharge pipe 650 is discharged to the outside to generate a negative pressure inside the venturi pipe 660.

The slaked lime tank 670 has a built-in slaked lime inside and a blower 671 is formed on the inner upper surface of the slaked lime tank 670. The upper surface of the slaked lime tank 670 and the venturi pipe 660 And a spray pipe 672 is provided in the venturi pipe.

A flow rate sensor 673 for detecting the discharge of air is formed in the spray tube 672.

The water tank 680 has a water pipe on the upper surface thereof and is connected to a nozzle 681 formed at the end of the venturi pipe 660. And water is sprayed to the nozzle 681 by a pressure means such as a pump (not shown).

As for the function and operation of such a safety device,

When the electrolytic solution in the reservoir tank 500 is vaporized or chemically changed, the pressure of the reservoir tank 500 is increased. When the pressure is increased, the pressure causes the disk 610 to overcome the elastic force of the spring 630 and to rise along the guide rod 620. When the pressure of the reservoir tank 500 drops, the disk 610 descends due to the elastic force of the spring 630 and the sheets 651 The discharge pipe 650 is sealed, thereby blocking the reservoir tank 500 from the outside air.

Since the vapor containing the electrolytic solution is harmful to human body, there is a need to neutralize the strong acid vapor when released into the air, and the vapor can be neutralized by the calcium hydroxide powder. The electrolytic solution and the slaked lime are neutralized by the following reaction formula.

SO ₂ + Ca (OH) ₂ = CaSO ₃ + H ₂ O

When the negative pressure is generated in the venturi pipe 660 by the structure of the venturi pipe 660 when the steam exits through the discharge pipe 650 and is discharged to the outside through the venturi pipe 660, The air in the hydrated lime tank 670 is discharged through the spray pipe 672.

Wherein the planar heating element comprises 0.5 to 7 parts by weight of carbon nanotube particles, 31 to 35 parts by weight of graphite particles, 5 to 30 parts by weight of a mixed binder, 29 to 80 parts by weight of an organic solvent, 0.5 to 5 parts by weight of an organic solvent, By weight.

Since the heat generating element having the above composition can maintain the heat resistance even at a temperature of 200 ° C or higher, the resistance change according to the temperature is small, stable, high temperature can be generated at low voltage and low power, and energy efficiency is excellent. It is possible to effectively prevent the freezing of the water tank.

As described above, the present invention facilitates the replenishment of the electrolyte solution in the battery, prevents the electrolyte solution from leaking from the injection device, filters the impurities contained in the electrolyte solution, and has corrosion resistance against the electrolyte solution, So that it is possible to neutralize the electrolyte vapor ejected from the reservoir tank.
