-10562 No. 1-5
In the water resistor described in Japanese Patent No. 3441, there is no description about a processing means when water is excessively supplied into the base electrode of the water resistor. Therefore, in a normal state, the control system forcibly circulates such that a predetermined amount of water is always supplied to the inside of the base electrode.However, the control system breaks down, or the water in the base electrode expands due to an increase in temperature, or When the buried amount of the insulating sheath cylinder that rises and falls in the base electrode is large, a situation where the water level rises to a predetermined position or more and water flows out of the base electrode may occur. The water flowing out of the base electrode is hot water at about 70 ° C.

[0004] When such a situation occurs, there is a possibility that an accident such as an electric leakage or a burn of an operator may occur.
An object of the present invention is to provide a treatment device for excess supply water that has solved such a disadvantage.

[0005]

According to the present invention, an electrode connected to a power supply device such as a generator can also be used in a water tank circulating and supplied with water, for example, a cylindrical base electrode. In the open-type water resistor that performs a measurement test of the output characteristics of the power supply device by adjusting the power consumption using water as a resistance, when the water in the water tank flows out of a predetermined water level or more. An open-top storage tank that receives only the entire amount of effluent water is provided. Almost 100% was recovered and reused.

[0006]

According to the present invention, all of the water flowing out of the open-top water tank is temporarily stored in the open-top storage tank, and then the opening / closing valve is opened, and the water in the circulation supply path is opened by the negative pressure suction force of the circulation pump or the like. To the water tank and supplied again into the water tank. Therefore, the water flowing out of the water tank does not leak outside.

In each of the mounting holes 4 of the water collecting tank 5, the lower ends of three cylindrical open base electrodes 6 (only one is shown) serving as a water tank to which water is supplied are tightly fitted and fixed. It faces the inside of the water tank 5.

On the other hand, the side wall of the water collecting tank 5 extends upward to a position corresponding to the upper end opening of the base electrode 6, and forms an upper open storage tank 9 having the upper plate 5a as a bottom plate.

As shown in FIG. 1, a drain port 8 is opened at the lower end of the side wall, One end of the communication pipe 7 is fitted and fixed to the drain port 8.

The storage tank 9 having an open top is provided with a second pump
The suction port is connected to the suction port via a communication pipe 7. The communication hype 7 is provided with an open / close valve 14. Therefore, when the pump 24 is operated with the opening and closing valve 14 opened, a negative pressure suction force acts on the storage tank 9. Then, the entire amount of excess electrode water in the storage tank 9 is discharged from the discharge port 8, and at the same time, the on-off valve 14 is closed to prevent air from being sucked.

Next, a mechanism for circulating the electrode water will be described. As shown in FIG. 1, the other end of the drain pipe 28 having one end connected to the water collecting tank 5 is connected to a first suction port of the pump 24. The discharge side of the pump 24 is a circulation pipe 23

Therefore, the water supply pipe 27, the base electrode 6, the water collecting tank 5, the drain pipe 28,
The pump 24, the circulation pipe 23, the pure water device 25, the circulation pipe 22, and the cooler 26 form a circulation path of the electrode water. The suction port itself of the pump 24 and the drain pipe 28 connected to the suction port constitute a negative pressure portion of the circulation path.

Next, the details of the open type water resistor 1 will be described. The three upper open base electrodes 6 have the same configuration, and a main electrode and an insulating sheath, which will be described later, are disposed inside thereof. Since the cylinder has the same configuration, only the base electrode 6 will be described below, and description of other base electrodes (not shown) will be omitted.

As is apparent from FIG. 2, the main electrode 10 disposed in the base electrode 6 is substantially cylindrical, and the vicinity of the upper and lower ends is gradually reduced toward each end in order to suppress arcing. It is diametered, narrowed down toward the axis and becomes a round shape,
The upper and lower ends are opened concentrically with the peripheral surface. A support 12 fixed to an insulating insulator 11 is tightly fitted into the main electrode 10 from the lower end thereof.
And an insulating insulator 11 having a T-shaped conductive terminal rod 1 on its side.
3 is inserted. The main electrode 10 is liquid-tightly supported on the bottom plate 5 b of the water collecting tank 5 via the insulating insulator 11. The main electrode 10 is set to have a large diameter and a small distance from the base electrode 6. The main electrode 10

A rack 19 is vertically fixed to the a and b, and the support frame 17 is fixed to a support plate 21 fixed to a motor 20 having a gear that meshes with the rack 19. Therefore, as the motor 20 moves up and down by being guided by the rack 19, the insulating sheath tube 16 moves up and down together with the other two insulating sheath tubes along with the support frame 17.
By controlling the vertical movement of the insulating sheath tube 16, the exposure length of the main electrode 10 facing the base electrode 6 is controlled, and the power consumption is adjusted.

Next, the operation of this embodiment will be described.
First, pure water from the water supply pipe 27 is supplied into the base electrode 6 to a level at which the main electrode 10 is buried.
The electrode water supplied into the base electrode 6 is drained from the water collecting tank 5 by a pump 24 by a drain pipe 28 and a circulation pipe 2.
After being sent to the pure water device 25 via the pipe 3 to remove impurities, it is sent to the cooler 26 via the circulation pipe 22, cooled to a predetermined temperature or less, sent to the water supply pipe 27, and again returned to the base electrode. Circulate so as to be fed into 6. And
Water is supplied to the electrode water circulation path from a water storage tank (not shown) as necessary. On the other hand, the electrode water excessively supplied into the base electrode 6 falls naturally from the upper end into the storage tank 9 which is open at the upper part, and is temporarily stored in its entirety. When the opening / closing valve 14 is opened when an appropriate amount has been accumulated, the pump 24
, The entire amount of electrode water in the storage tank 9 is drained to the circulation pipe 23 through the communication pipe 7, and merges with the electrode water from the water collection tank 5 drained through the drain pipe 28 to produce pure water. It is sent to the water dispenser 25. When the entire amount of excess electrode water in the storage tank 9 is discharged to the drain pipe 28, the opening / closing valve 14 is closed. Therefore, nearly 100% of the excess feed water is recovered and reused, and the circulation path is a completely closed type.

On the other hand, a generator (not shown) to be measured and tested is electrically connected to each main electrode 10 in a predetermined state.
The generator is operated to consume the output power of the generator by using the electrode water supplied into the base electrode 6 as a resistance, and also controls the drive of the motor 20 to raise and lower each insulating sheath tube 16 to reduce the power consumption. Is adjusted, and the output characteristics are measured.

Next, a second embodiment will be described with reference to FIG. As shown in FIG. 3, the water collecting tank 5 of the open type water resistor 30 is provided.

It faces the inside of the water tank 5.

An outlet 31 is opened at the upper end of the side wall of the base electrode 6 which is open at the top. One end of an outlet pipe 32 is fitted and fixed to the outlet 31, and the other end of the outlet pipe 32 is open at the top. It is located above the storage tank 33. When the electrode water is excessively supplied to the base electrode 6, the storage tank 33 causes the entire amount of the electrode water to flow out from the outlet 31 and naturally falls through the outlet pipe 32 to store the entire amount. belongs to. A drain port 34 is provided at the bottom of the storage tank 33, and is connected to the second suction port of the pump 24 via the communication pipe 7 provided with the open / close valve 14. Therefore, when the pump 24 is operated with the open / close valve 14 opened, a negative pressure suction force acts on the storage tank 33. Therefore, the excess supply water is recovered and reused almost 100%, and the circulation path is a completely closed type.

The other constructions and operations of the present embodiment are the same as those of the first embodiment, so that the same reference numerals are given to the corresponding components, and a detailed description is omitted.

In each of the above-described embodiments, the other end of the communication pipe 7 having one end connected to the drain ports 8, 34 of the storage tanks 9, 33 open at the top is connected to the second suction port of the pump 24. Although the connection is made, this may be connected to an appropriate position of the drain pipe 28. Further, the diameter of the vicinity of the upper and lower ends of each main electrode 10 is gradually reduced toward each end to form a narrowed radius toward the axis, but only the vicinity of the lower end is gradually reduced and the diameter is narrowed toward the axis. It may be formed in a shape. Furthermore, each main electrode 1
0 may not be cylindrical but may be cylindrical. In the case of this cylindrical shape, the vicinity of the reduced end portion becomes a complete spherical surface with the final end as a point or a curved surface that forms part of a spherical surface with the final end as a plane. Furthermore, each main electrode 10 can be supported at its upper end above each base electrode 6. Further, the lower end of each base electrode 6 is connected to a water collecting tank 5.
Each base electrode 6 is erected on an upper plate 5a formed of an insulator of the water collecting tank 5, and each base electrode 6
In addition to the configuration in which the bottom surface is closed, a drain port may be opened in the upper plate 5a, or each base electrode 6 may be provided in an open top water tank to which electrode water is supplied. In addition, each base electrode 6 is not limited to a cylindrical shape, and may have a polygonal shape or an elliptical cylindrical shape in plan view, or may be formed in a so-called funnel shape in which a peripheral surface extends obliquely with respect to an axis. In the case of this funnel shape, the peripheral surface of each main electrode 10 is also preferably formed in a funnel shape. Furthermore, the mechanism for raising and lowering each insulating sheath tube 16 is not limited to the combination of the rack 19 and the pinion that meshes with the rack 19, and the motor 20 linked to each insulating sheath tube 16.
