Description

Detailed Description of the Invention This invention provides continuous water flow for electrically insulating the electrical control unit from the supply side or the discharge side when performing electrical processing such as conditioning water by electrolysis. This invention relates to an electrical insulating device.

As this type of electrical insulation element, one formed by a siphon tube is known. Although this is effective in principle, it has the disadvantage that the electrical insulation deteriorates when limescale, electrolytic deposits, etc. accumulate during long-term use. In particular, when the amount of water supplied is large, it becomes unusable in a relatively short period of time.

Therefore, by swirling the continuously supplied water stream,
While achieving a continuous supply of water to the chambers partitioned by partition walls, a tank that is completely electrically divided is constructed using watershed members, and is free from practical inconveniences (limescale, electrolytic analysis). A mechanism was proposed earlier that could avoid damage to the electrical insulation due to debris.

However, the problem here is that if a failure occurs in the opening/closing operation of the on-off valves installed in each chamber, electrical continuity will immediately be established between the electrical control section and the supply or discharge side of the above mechanism. I have become in a state of
Or, it may no longer function as a divider due to overflow.

Therefore, the inventor installed an inverted umbrella-shaped water separator on the inclined shaft so that water can be discharged from the partitioned chamber without providing a movable part such as the above-mentioned on-off valve. The water separator is divided into a plurality of chambers, a watershed member is provided across the wall that partitions these chambers, and water is injected from above the inclined shaft.
A method of draining water from the bottom was proposed.

This eliminates operating parts such as on-off valves, so there is no malfunction, and electrical insulation of water can be achieved through natural flow. In order to increase the flow rate, the size of the water separator must be adjusted to the required size. Further, since the axis for rotational drive is inclined, there is a disadvantage that there is a lot of waste in terms of design space and that installation is difficult.

This invention was made based on the above-mentioned circumstances, and even if the size of the water separator is relatively small, a sufficient amount of water can be ensured, and moreover,
The present invention aims to provide a continuous water flow electrical insulating device that does not have moving parts such as on-off valves and can also have a shaft for rotational drive installed vertically.

Hereinafter, the present invention will be specifically explained based on illustrated embodiments. In the figure, reference numeral 1 denotes a rotating tank unit that is divided into multiple sets (3 or more) in the circumferential direction with partition walls 1a extending in the radial direction, and a vertical rotating shaft 2 in the center. Supported. As is clear from the figure, the above-mentioned unit is constructed in the shape of a dish with a raised outer peripheral wall. A gap 3 is formed between the rotating shaft 2 and the unit 1 to improve electrical insulation. On the upper side of the rotating shaft 2, above the unit 1, a water supply port 4 is opened near the center of rotation. A pulley 5 is provided on the upper part of the rotating shaft 2, and a drive pulley 7 is connected to this via a belt 6. The pulley 7 is attached to a drive shaft of a motor 8.

The unit 1 is provided with a watershed member 9 above the partition wall, which is centered around the rotation center of the unit 1 and straddles the partition wall. This water division member 9 has a structure that is fixed to the partition wall 1a of one of the rotating tank units 1, and does not structurally contact the other rotating tank unit, maintaining an appropriate electrically insulating space. .
For this reason, it is preferable that the partition wall 1a on the side where the attachment is performed is constructed slightly higher. Further, an annular lid 1b is attached to the unit 1 apart from the area of the watershed member 9.

Further, the water receiving tank 10 in which the above-mentioned unit 1 and the like are arranged is provided with a detecting section 11a of a water level detecting means 11 at a predetermined level of its drainage chamber 10a. This detection means 11 is the detection unit 1
When 1a comes into contact with water, a detection signal is output, and the opening of the on-off valve 12 provided at the water supply port 4 is controlled to be narrowed. Also, when you leave the water, the on-off valve 12
The opening degree of the valve is controlled in the direction of opening.

In this case, the rotation speed of the rotating tank (i.e., the rotating shaft 2
By appropriately setting the rotation speed of
On the opposite side, it can be discharged by centrifugal force.

That is, when the unit 1 is being rotated by the rotation of the rotating shaft 2, when water is supplied from the water supply port 4, water will enter the unit 1 at this point.
Also, when crossing between units, use the watershed member 9.
gives and receives water. The water that has entered unit 1 flows in the centrifugal direction at a predetermined speed due to the centrifugal force caused by the rotation of unit 1, but before it climbs up the outer peripheral wall of unit 1 and crosses the edge, it flows from water supply area A. Since it moves to the drainage area B, it is electrically insulated in this area.

When the amount of water supplied per unit time from the water supply port 4 increases, the area B for drainage will be expanded from _B1 to _B2 . For this reason, it is advisable to design the area in advance so that it does not fall into the A area.

If the water level in the water tank 10 exceeds a predetermined value, the amount of water supplied from the water supply port 4 per unit time is reduced. If no water is discharged from the water tank 10, the signal from the detection mechanism 11 is maintained, the opening degree of the on-off valve 12 continues to decrease, and eventually closes. When the water level decreases, the on-off valve 12 is operated in the opening direction, and eventually becomes fully open.

As described in detail above, the present invention includes a rotating tank unit that is circumferentially divided with partition walls in the radial direction, and a watershed member that straddles the partition wall of the rotating tank unit is provided above the partition wall. At the same time, a water supply port is provided near the center of rotation and above the watershed member, and the rotational speed of the rotating tank and the shape of the outer periphery are set so that the water drains beyond the outer periphery of the rotating tank unit, and centrifugal force Since it is configured to drain water, there is no risk of malfunction as there are no moving parts such as on-off valves.Moreover, by using centrifugal force, water can be discharged in a short time, and a relatively small water separator is required. Even if there is a problem, a sufficient flow rate of water can be processed, and the rotary axis can be vertically designed, which is advantageous.
