Description

[Detailed Description of the Invention] This invention relates to an improvement of a float-type water collecting device used, for example, to draw out supernatant water from a settling tank.

Conventional water collection devices of this type include those in which a water collection gutter is floated in a tank using a float, and the supernatant liquid is removed from the lower part of the water collection gutter using a bellows; In order to prevent the device from swinging, there is a device that has a guide rod added to the above-mentioned device.

However, the conventional type has the disadvantage that the water collection gutter swings or tilts, and in order to prevent this, a guide rod is added, which prevents the sliding contact between the guide rod and the water collection gutter. The problem is that the water collection gutter cannot accurately follow the rise and fall of the water level.

This idea solves the above-mentioned problems with conventional products. It has a simple structure and can be manufactured at low cost. It also has extremely low resistance when the float moves up and down, and operates accurately in response to fluctuations in water level. This is the realization of a water collection device.

Below, we will explain this idea in detail based on the drawings.
As shown in the figure, a float 2 with a water collection gutter 1 attached to its lower part is installed in a tank, and a telescopic water collection pipe 3 with its upper end fixed to the bottom of the water collection gutter 1 is installed at the lower end of the tank. The water collection pipe 3
The float 2 is fixed to a drain pipe 4 which is erected through the float 2, and the drain pipe 4 is provided with a pair of elongated holes 5, into which the anti-rotation rod 6 provided on the float 2 is inserted. It is engaged.

In the figure, reference numeral 7 indicates a tank wall, and reference numeral 8 indicates a support for the drain pipe 4.

Since the water collection device according to this invention is configured as described above, the water collection gutter 1 moves up and down in accordance with the vertical fluctuation of the water level in the tank, and the supernatant water in the tank flows into the water collection gutter 1. Then, it enters the drain pipe 4 through the long hole 5 through the water collecting pipe 3, and can be taken out of the tank.

During this water intake operation, in this invention, the drain pipe 4 is connected to the float 2. Since it is installed vertically through the water collection gutter 1 and water collection pipe 3, when the water collection pipe 3 expands and contracts as the water level fluctuates, the water collection gutter 1 swings with the drain pipe 4 acting as a guide. It does not tilt or tilt, and can move up and down in a balanced state to achieve stable water intake.

Further, since the long hole 5 provided in the drain pipe 4 is engaged with the anti-rotation rod 6 provided on the float 2, the water collection gutter 1 is prevented from rotating when supernatant water flows in. I can do it.

In conventional water collection devices of this type, a special guide rod is used to prevent the supernatant water from swinging or tilting as the supernatant water flows into the water collection gutter 1, but in this invention, ,
In addition to using the drain pipe 4 as a guide, the long drain hole 6 is also used to prevent the water collection gutter 1 from rotating, and it is structurally simpler than conventional products. It can be manufactured at low cost.

As described above, the water collection device according to the present invention has a simple structure and can be manufactured at low cost, while exhibiting outstanding performance that is not found in conventional products.
