Abstract

PURPOSE:To treat a sufficient amount of water with a small water separator, while discharging the water in a short time, by extending the upper partition walls of rotary cell units along a circumferential direction at the outer edges of the rotary cell units to lengthen the passages of water in the units. CONSTITUTION:When water is poured through a water supply opening 4, a rotating direction is in a zone A and the discharge of water is performed in a zone B by viewing the figure horizontally. When an amount of water to be supplied through the water supply opening 4 per unit time increases, the zone B for discharging water is expanded from B1 to B2. When the water level in a water accepting cell 10 exceeds a predetermined value, the amount of water to be supplied through the water supply opening 4 per unit time decreases. If the discharge of water from the water accepting cell 10 is not carried out, a signal from a detecting means 11 is held as such to reduce the opening rate of a switch valve 12 and to close it in the end. When the water level is lowered, the switch valve 12 is operated toward the opening state and completely opened finally.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides continuous water flow electricity for electrically insulating the electrical control section from the supply side or the discharge side when performing electrical processing such as conditioning water by electrolysis. It relates to insulation devices.

As this type of insulating element, one using a siphon tube is known. This is effective in principle, but if limescale, electrolyte deposits, etc. accumulate during long-term use,
The disadvantage is that electrical insulation is reduced. <K, if the amount of water supplied is large, it will become unusable in a relatively short period of time.

Therefore, by swirling the continuously supplied water stream to achieve a continuous supply of water to the chambers partitioned by partition walls, we constructed a cypress that is completely electrically divided using watershed members. A mechanism was previously proposed which made it possible to avoid practical inconveniences (breakage of electrical insulation due to limescale, electrolytic deposits, 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, the electrical control side and the supply or discharge side of the above mechanism will immediately be disconnected. It may become conductive or the dividing function may become ineffective due to overflow.

Therefore, the inventor installed an inverted umbrella-shaped water separator on one 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. We proposed a method in which the water separator is divided into multiple chambers, a watershed member is installed across the walls that partition these chambers, and water is injected from above the inclined shaft and drained from the bottom.

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. The water separator must be sized to the required size.

Furthermore, since the axis for rotational drive is inclined, there is a disadvantage in that there is a lot of waste in terms of design space, and the 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 indicates a partition wall 1 extending in the radial direction.
A is a rotary tank unit that is divided into a plurality (three or more) in the circumferential direction, and is supported by a vertical force rotation shaft 2 in the center. 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, there is a water inlet 4 near the center of rotation.
is opened. 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 that leans toward the center of rotation 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, does not structurally contact the other rotating tank unit, and maintains 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 body 1b is attached to the unit 1 apart from the area of the watershed member 9.

In addition, a water tank 10 in which the above unit 1 etc. are arranged on the upper part.
A detection section 11a of a water level detection means 11 is provided at a predetermined level of the drainage chamber 10a. When the detection section tta 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. Also, once you get out of the water,
The opening degree of the on-off valve 12 is controlled in the direction of opening.

In this case, if the rotation speed of the rotating tank is set appropriately, the partition wall 1
Since the length of time for water to flow through the spiral water passage formed by a is determined, at what point does drainage begin after water is supplied?
The point at which it will end is determined by itself.

That is, when the unit 1 is rotated by 20 rotations of the rotation axis, when water is supplied through the water inlet 4, water enters the unit 1 at this side, and when crossing between the units, The watershed member 9 distributes 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 unit's 10 rotations, but before it climbs up the wall around the outside of unit 1 and crosses the edge, it flows away from the water supply area. Since it moves to the drainage area B, it is electrically insulated in this area.

Now, when viewed from above, during the period when water is being received from the water supply port 4, it is sufficient that the area is A in the rotational direction, and the drainage is in the B area. When the amount of water supplied per unit time from the water supply port 4 increases, the area B for drainage changes from B to B! It will be expanded to. For this reason, it is advisable to design the device in advance so that it does not fall into area A.

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. Water tank 1
If no water is discharged from 0, the signal from the check button mechanism 11 is maintained, the opening degree of the on-off valve 12 continues to be decreased, and the end point is K.
will close. If the water level decreases, on the other hand, the on-off valve 1
2 is operated in the opening direction, and K is fully opened at the end.

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, 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 rotating tank unit to form a long water passage in the unit. Since the water is drained by centrifugal action using the rotational force applied, 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 relatively small amounts of water can be discharged. Even with a separator, the water passage is formed long by the partition wall, so it can handle a sufficient flow of water, and the axis of rotation is vertical, making it easy to install. effective.
