Description

[Detailed description of the invention] [Field of industrial application] This invention is a novel design that can be used in various types of aquariums by providing a compact overlayer on the outside of the aquarium without leaving any unused parts, which does not occupy the upper surface of the aquarium. This invention is characterized by the ability to eliminate stagnant water.

[Conventional technology]

Most of the conventionally provided filtering devices for breeding aquariums of this type are of the type that is mounted on the top surface of the breeding aquarium, as shown in Japanese Utility Model Publication No. 14958/1983.

That is, an overtank filled with overfill material was provided on the upper surface in the longitudinal direction of the rearing aquarium, a pump was provided at one end of the overtank, and a reflux port was provided at the other end.

In addition, there are also systems in which a tank is installed outside the rearing tank (Japanese Patent Publication No. 12935/1983, etc.).
48-24238, etc.) are also provided.

[Problem that the invention attempts to solve]

The above-mentioned rearing tank overpass device placed on the top of the rearing tank needs to be prepared according to the size of the rearing tank to be used, and its mounting position is also limited, and it inevitably occupies most of the upper surface of the rearing tank. It was hot.

Furthermore, although it has a large and sufficient excess area, there is actually an unused area, which cannot be said to be rational.

Furthermore, in the breeding tank filtration device provided on the top surface of the breeding tank and on the outside of the breeding tank, the direction of water flow is always constant, resulting in a stagnant water area.

The present invention attempts to eliminate the above-mentioned drawbacks.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention has a discharge port of a water pump installed inside the rearing tank installed at one end of the overtank provided outside the rearing tank, and a discharge port of the water pump installed inside the overtank is introduced into the other end of the overtank. A gutter-like part is provided which is open and curved outward on both sides, and the gutter-like part is provided with a return port that fits inside the gutter-like part and is rotatable in the form of a gutter in the horizontal direction. .

[Effect]

In this invention, the water pump P is placed in the breeding tank B.
A tank C is provided outside the breeding tank B.

Therefore, most of the upper surface of the rearing tank B is open and can be used for other purposes, for example, for placing ornaments such as flowerpots.

In the present invention, when the motor 1 of the pump P is driven, water containing impurities in the rearing tank B is supplied from the discharge port 5 to the upper surface of the overfill material 10 at one end of the overfill tank C by the action of the impeller 3. The water that has descended through the weir plate 11 passes through the filtration tank C.
It is levitated and supplied to the other end.

Then, the water is widened through the reflux port 12 and refluxed into the rearing tank B.

In the present invention, the gutter-shaped return port 12 is further configured to be horizontally rotatable.

Therefore, by changing the direction of the reflux port 12 every day or every hour, stagnant water can be eliminated.

Furthermore, unlike the conventional device, the mounting position of the device of the present invention is not limited.

Therefore, it is easy to move it according to the installation location, etc., and it has a novelty.

〔Example〕

The drawings show one embodiment of the present invention, and the details thereof will be explained below in detail with reference to the drawings.

In the figure, P is a pump, 1 is a motor, 2 is a main shaft, 3 is an impeller, 4 is a strainer, and 5 is a discharge port.

In the present invention, the discharge port 5 is introduced into an overtank C provided outside the rearing tank B at one end.

That is, the engaging portion 6 configured in advance on the side of the tank C
The lower part of the discharge part 5 of the water pump P is engaged with the
be made into one.

Therefore, in the present invention, the water pump P and the tank C are provided so as to straddle the upper edge of the rearing tank B.

Next, the overtank C will be described.

The tank C has an elliptical shape in plan and has a flange 8 on one side thereof, which is placed on the upper edge of the breeding tank B.

A batten 9 is provided at one end of the overtank C, that is, on the side of the discharge port 5 of the water pump P, at an appropriate distance from the bottom, and the upper surface thereof is filled with overfill material 10 such as a felt-like nonwoven fabric to an appropriate thickness. be done. moreover,
A weir plate 11 is provided at a suitable position on the other end side of the tank C with an appropriate distance from the bottom.

Therefore, the water in the rearing tank B that is supplied from the discharge port 5 of the pump P to one end of the overtank C is supplied to the upper surface of the overfill 10 and descends through the overfill 10 to the bottom of the weir plate 11. It passes through and is floated and supplied to the other end of the tank C.

Next, at the other end of the overtank C, there is provided a gutter-like part 13 which is open to the rearing tank B and has both sides curved outward. A freely trough-like reflux port 12 is provided.

Details of the reflux port 12 are shown in FIGS. 5 to 7 and others.

That is, a gutter-like portion 13 is formed with the flange 8 portion as a bottom and both sides are curved outward, and a protrusion 14 is formed at the center of the curvature. A gutter-like reflux port 12 is provided.

In the figure, 15 is a guide plate provided above the reflux port 12, and has curved guides 16 at both ends that fit inside the upper end of the reflux port 12, and screw holes provided on the outside of the curved portion on both sides of the gutter-shaped portion 13. A threaded hole 18 is provided which fits with 17.

Therefore, the inside of the gutter-like portion 13 and the protrusion 14
If the reflux port 12 is fitted to the reflux port 12, the guide plate 15 is placed on the upper surface of the reflux port 12, and the bolt 19 is screwed into the threaded hole 18 of the reflux port 12 and the threaded hole 17 of the gutter-like portion 13.
The recirculation port 12 is restricted from moving in the vertical direction and is rotatable only in the horizontal direction.

In the figure, 20 is an O-ring that seals between the gutter-like portion 13 and the reflux port 12.

Next, the installation of the above device will be described.
In the present invention, as shown in FIG. 8, the flange 8 is placed on the upper edge of the breeding tank B, and includes an upper clamping plate 21, a lower clamping plate 22, a tightening bolt 23,
A flange 26 on the inner side of the upper edge of the rearing tank B is held between the butterfly nut 24 and the parallel adjustment butterfly bolt 25.

That is, there are many ribs 27 on the upper surface of the flange 8.
A rib 28 that engages with the rib 27 is formed on the lower surface of the upper clamping plate 21.

On the other hand, a cushion member 29 is provided at one end of the upper surface of the lower clamping plate 22 to abut against the lower surface of the flange 26 on the inner side of the upper edge of the rearing tank B.

A tightening bolt 23 and a wing nut 24 are provided between the upper clamp plate 21 and the lower clamp plate 22.
It is screwed onto the lower clamp plate 22 and is attached as shown in the figure by a parallel adjustment butterfly bolt 25 whose tip is brought into contact with the lower surface of the clamp upper plate 21.

FIG. 9 shows the thermo-mounting section. That is, the cut-out portion 30 provided in advance on the flange portion 8
A detail 33 at one end of a mounting plate 32 having a thermo mounting hole 31 is engaged with the mounting plate 32 .

In the figure, numeral 34 is the lid of the over-tank C, and in the case of the embodiment shown in the drawing, as shown in FIGS. 2 and 10, removable circular plates 35 are provided at appropriate intervals. 36 are provided.

This is configured so that flowers can be grown using hydroponics.

That is, if the connecting portion of the circular plate 35 is cut and the circular plate 35 is removed, and then seeds are introduced from that portion, the seeds will be placed on the overfill 10 by water containing nutrients supplied from the rearing tank B. It can be germinated and grown.

[Effect of idea]

According to the present invention, it is possible to provide a novel overtank that does not occupy the upper surface of the breeding aquarium, does not cause stagnant water, is compact, and does not have any unused parts.
