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 insulating element, one using a siphon tube is known. Although this is effective in principle, it has the disadvantage that the electrical insulation deteriorates as limescale, electrolyte deposits, etc. accumulate during long-term use. Especially 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 caused by spills, etc.

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 provided an inverted umbrella-shaped water separator on the inclined shaft so that water could 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 breakdown, and electrical insulation of water can be achieved through natural flow. However, due to natural flow, water flow per unit time In order to increase the amount, the size of the water separator must be adjusted to the required scale. 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 circumstances, and even if the size of the water separator is relatively small, it can ensure a sufficient flow of water, and it does not have moving parts such as on-off valves. Another object of the present invention is to provide a continuous water flow electrical insulating device in which the shaft for rotational drive can be installed vertically, and the rotational speed of the shaft can be set at a considerably high speed.

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 a plurality of units (three or more units) in the circumferential direction with partition walls 1a extending in the radial direction. is supported by As is clear from the figure, the bottom of the unit rises as it approaches the outer periphery, and the partition wall 1a is configured to extend in the circumferential direction as it approaches the outer periphery. 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,
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 watershed member 9 has a structure that is fixed to the partition wall 1a of one rotating tank unit 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 etc. are arranged is placed at a predetermined level of the drainage chamber 10a.
A detection section 11a of the water level detection means 11 is provided. When the detection section 11a comes into contact with water, the detection means 11 outputs a detection signal and controls the opening of the on-off valve 12 provided at the water supply port 4 in a direction to narrow it down. Furthermore, when the water is removed, the opening of the on-off valve 12 is controlled in the direction of opening.

In this case, by appropriately setting the rotation speed of the rotary tank, the length of time for water to flow through the spiral water passage formed by the partition wall 1a is determined, so at what point does drainage start after water supply and at what point? Whether it will end or not will be determined by itself.

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 enters the unit 1 at this point, and the watershed member 9 distributes the water when it crosses between units. 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 discharge area B, it is electrically insulated during this period.

Now, when viewed from above, the period during which water is being received from the water supply port 4 is in region A in the rotational direction, and the discharge is in region B. 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. In addition, a water supply port is provided above the watershed member near the center of rotation, and the partition wall is extended in the circumferential direction at the outer periphery of the rotary tank unit to form a long water passage in the unit, and the water passage in the unit is configured to be long. Since it uses the rotational force applied to the centrifugal action to drain water, there is no risk of malfunction as there are no moving parts such as opening/closing valves.Furthermore, since centrifugal force is used, water can be discharged in a short time and is relatively small. Even with a water separator, the water passage is formed long by the partition wall, so it can handle a sufficient flow of water, and the rotation axis is vertical, making it easy to install and not unreasonable in terms of design. There are effects such as no.
