The submersible pump 7 is a suction device for sucking the liquid W filled in the bubble conduit 6, and is installed at the bottom of the water tank 2. The submersible pump 7 includes a suction port 7a for sucking the liquid W into the inside thereof, and a discharge port 7b for discharging the liquid W from the inside thereof. The liquid W sucked into the suction port 7a is discharged from the discharge port 7b into the water tank 2. Can be discharged to The submersible pump 7 includes, for example, a filter 7c formed of a porous fibrous body having a large number of micropores, and is included in the liquid W sucked into the submersible pump 7 by the filter 7c. The pollutants can be collected, and the liquid W can be discharged from the discharge port 7b into the water tank 2. Therefore, by operating the submersible pump 7, the liquid W in the water tank 2 can be purified.

On the upper end surface of the vertical conduit 6a of the bubble conduit 6,
A water intake 8 is provided as an opening communicating with the inside of the bubble conduit 6. The water intake port 8 is an opening through which the liquid W in the water tank 2 flows into the bubble pipe line 6.

It is possible to prevent the aquatic organisms from being drawn into the water intake port 8 by the porous material while the liquid W flows into the bubble conduit 6 from above.

Above the vertical pipe 6a of the bubble pipe 6 provided with the water inlet 8, a bubble collecting member 10 is arranged at a distance from the upper end surface of the vertical pipe 6a. Bubble collecting member 1
Reference numeral 0 denotes a substantially hemispherical dome-shaped member that collects the bubbles B released from the bubble nozzle 3 and rising to the upper part of the water tank 2 in the vicinity of the water inlet 8, and is concavely curved on the surface facing the water inlet 8. A guide surface 10a is formed. The guide surface 10 a can receive the air bubbles B floating from the bottom of the water tank 2 and collect the air bubbles B near the water inlet 8. In FIG. 1, the bubble collecting member 10 is connected to the vertical pipe 6a.
The illustration of a support member for supporting above is omitted.

A horizontal line 6b in the bubble line 6 has a gas-liquid separation tube 11 near its end on the submersible pump 7 side.
The gas-liquid separation tube 11 is formed in a linear tubular body with a transparent material such as a transparent resin or transparent glass. The lower end of the gas-liquid separation pipe 11 is connected to the outer peripheral upper surface of the horizontal pipe 6b and communicates with the horizontal pipe 6b, while the upper end of the gas-liquid separation pipe 11 is above the liquid surface of the liquid W from the upper part of the water tank 2.

An exhaust port 11a, which is an opening communicating with the inside of the tube 1, is provided, and air bubbles B that have entered the gas-liquid separation tube 11 from the outlet 11a can be discharged to the atmosphere.

The gas-liquid separation pipe 11 separates the bubbles B flowing in the bubble pipe 6 from the liquid W in the bubble pipe 6 before flowing into the suction port 7 a of the submersible pump 7, and discharges the bubbles B from the discharge port 11 a. Since the bubbles B are released into the atmosphere, the bubbles B flowing in the bubble pipe 6 can be prevented from flowing into the submersible pump 7.
Therefore, the gas-liquid separation tube 11 prevents the bubbles B from flowing into the submersible pump 7, so that the suction force of the submersible pump 7 due to the bubbles B and the damage of the submersible pump 7 can be suppressed.

Next, the operation of the ornamental water tank system 1 will be described. First, the air pump 5 and the submersible pump 7 are operated. When compressed air is supplied to the air supply pipe 4 by the air pump 5, the compressed air is supplied to the bubble nozzle 3 via the air supply pipe 4. The compressed air that has reached the bubble nozzle 3 is released from the micro holes 3a of the bubble nozzle 3 into the liquid W in the water tank 2, and the released compressed air is composed of a large number of bubbles B.
And floats upward in the water tank 2 along the floating path 9.

On the other hand, the submersible pump 7 causes the bubble line 6
When the liquid W inside is sucked, the bubble W
Inside, a flow is generated from the water intake port 8 to the suction port 7a of the submersible pump 7. With this flow, the liquid W in the water tank 2
Flows into the vertical pipe 6a of the bubble pipe 6 from the water intake port 8, flows in the vertical pipe 6a, flows in the horizontal pipe 6b, and is sucked into the suction port 7a of the submersible pump 7. You. The sucked liquid W is returned to the inside of the water tank 2 from the discharge port 7b of the submersible pump 7 after the contaminants are removed by the filter 7c and filtered.

By the way, the bubble B released from the bubble nozzle 3 floats in the liquid W of the water tank 2 along the floating path 9 and reaches the vicinity of the water intake port 8 provided in the bubble pipe line 6. Part of the liquid W is drawn into the water intake 8 and is drawn from the water intake 8 to the vertical pipe 6 a of the bubble pipe 6. On the other hand, a part of the air bubbles B passing through the water intake port 8 is collected around the water intake port 8 along the guide surface 10a of the air bubble collecting member 10, and the collected air bubbles B are transferred to the liquid W toward the water intake port 8.
With the flow of water, the vertical line 6 of the bubble line 6
It is invited into a. Note that the remaining bubbles B not collected by the bubble collecting member 10 further float in the liquid W,
Released into the atmosphere.

The bubbles B attracted into the vertical pipe 6a of the bubble pipe 6 flow downward along the vertical pipe 6a together with the liquid W by suction by the submersible pump 7, and then flow through the horizontal pipe 6b. It flows toward the submersible pump 7. Bubble line 6
Is a tubular body made of a transparent material, so that the flow of the bubbles B in the bubble channel 6 is watched by the viewer through the wall material 2a of the water tank 2. When the bubble B flowing in the bubble channel 6 reaches the gas-liquid separation tube 11, the bubble B is discharged into the atmosphere from the outlet 11 a through the gas-liquid separation tube 11, and is discharged to the atmosphere.
It is separated from the liquid W flowing inside.

As described above, according to the ornamental water tank system 1 of this embodiment, since the bubble pipe 6 through which the bubbles B flow together with the liquid W is formed of a transparent material, the water tank 2 can be viewed from the outside. This makes it difficult for the user to notice the presence of the bubble channel 6. In addition, since the bubble channel 6 extends in a direction different from the floating path 9 of the bubble B discharged from the bubble nozzle 3 (the two-dot chain line in FIG. 1), the bubble channel 6 By causing the bubbles B to flow together with the liquid W in the inside, the bubbles B can flow in a direction different from the floating path 9 so that the bubbles B can appear as if they are freely floating in the liquid W in the water tank 2. it can.

By causing the bubbles B to flow in the bubble conduit 6, the bubbles B floating in the liquid W in the water tank 2 can normally flow in a direction contrary to the viewer's expectation. . Therefore, due to the unexpected flow of the bubble B,
A person watching the inside of the water tank 2 can be enjoyed through the wall material 2a of the water tank 2, and the inside of the water tank 2 can be decorated by an unexpected flow of the bubbles B. In addition, if the inside of the water tank 2 is lit up, the inside of the water tank 2 can be further decorated by the light reflected by the bubbles B, so that the interest of the viewer can be attracted.

Moreover, since the bubbles B released from the bubble nozzle 3 float in the liquid W in the water tank 2 along the rising path 9 and are sucked into the bubble pipe 6 from the water intake 8, the bubbles B While the liquid B floats in the liquid W in the water tank 2, the liquid W
It can supply oxygen into it.

When the liquid W flowing into the storage tank 81 is decelerated, the bubbles B mixed in the liquid W float in the liquid W stored in the storage tank 81, and the air B flows from the open portion on the upper surface of the storage tank 81 to the atmosphere. Released inside. As a result, the bubbles B can be separated from the liquid W flowing into the storage tank 81.

After the bubbles B are separated, the liquid W in the storage tank 81 flows into the conduit 83 at an increased flow rate by suction of the pump 84, and is sucked into the suction port 84 a of the pump 84 via the conduit 83. Is done. Therefore, it is possible to suppress the bubbles B from being mixed into the liquid W flowing into the submersible pump 7, and to suppress a decrease in the suction force of the submersible pump 7 due to the bubbles B and damage to the submersible pump 7. Thereafter, the liquid W flowing into the pump 84 is returned to the water tank 2 from the discharge port 84b via the return pipe 85.

FIG. 8 is a view showing a state in which a bubble B is generated from the liquid W flowing in the bubble pipe 6 in the ornamental water tank system 90 of the ninth embodiment.
FIG. 2 is an external perspective view of a gas-liquid separation tube 91 for separating
In the drawing, the flows of the liquid W and the bubbles B in the bubble channel 6 are shown by dotted arrows. FIG. 8 shows a part of the bubble channel 6.

The ornamental aquarium system 90 of the ninth embodiment comprises:
This is a modification of the form of the gas-liquid separation tube 11 in the ornamental aquarium system 1 of the first embodiment. As shown in FIG.
The gas-liquid separation tube 91 is formed in a linear hollow cylindrical body with a transparent material such as a transparent resin or transparent glass, and the lower end thereof is connected to the outer peripheral upper surface of the horizontal pipe 6b and communicates with the horizontal pipe 6b. are doing.

The upper end of the gas-liquid separation tube 91 is immersed in the liquid W, and a number of discharge holes 91 a communicating with the inside of the gas-liquid separation tube 91 are formed in the upper end surface of the gas-liquid separation tube 91. ing. As described above, according to the ornamental water tank system 90 of the ninth embodiment, when the mixed flow of the liquid W and the bubbles B flowing in the horizontal pipe 6b of the bubble pipe 6 reaches the lower end of the gas-liquid separation pipe 91, Floating inside the gas-liquid separation tube 91, the many discharge holes 91a
From the gas-liquid separation pipe 91. As a result, the bubbles B can be separated from the liquid W flowing in the bubble pipe 6.

The number of the gas-liquid separation tubes 91 is not necessarily limited to one. For example, a plurality of gas-liquid separation tubes 91 may be provided in the bubble line 6. In the ninth embodiment, the shape of the gas-liquid separation tube 91 is a hollow cylindrical body.
The shape of the gas-liquid separation tube is not necessarily limited to this, and may be, for example, a hollow rectangular parallelepiped.

As described above, the present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. Can easily be inferred.

For example, in the first embodiment, the wall material 2 of the water tank 2
a, the bubble line 6 and the gas-liquid separation tube 11 are formed of a transparent material, respectively.
Is not necessarily a transparent material, and may be a translucent material such as a translucent resin or translucent glass as long as it is a material that can transmit light (light transmissive material). That is, the viewer who watches the inside of the water tank 2 can move the bubbles B floating in the water tank 2 along the floating path 9 and the bubbles B flowing in the bubble channel 6 and the gas-liquid separation pipe 11 to the water tank 2. It just needs to be watched from outside.

Further, it is not always necessary to breed aquatic organisms in the aquarium 2 of the aquarium system 1, and even if the aquarium system 1 is simply installed as a part of the interior in an installation place such as a room, the aquarium can be viewed. good. Further, the material of the filter 7c provided inside the submersible pump 7 is not necessarily limited to a porous fibrous body, and may be, for example, a porous ceramic material having a large number of micropores. Further, it is not always necessary to provide the filter 7c inside the submersible pump 7, and for example, it is also possible to connect the discharge port 7b of the submersible pump 7 to a filtering device, to purify the liquid W with the filtering device, and then to return the liquid W to the water tank 2. good.

In the first embodiment, air bubbles B
In order to collect water, the bubble collecting member 10 is disposed above the water intake 8. However, the bubble collecting member 10 does not necessarily need to be disposed above the water intake 8, and is provided in the bubble conduit 6 by the submersible pump 7. If the suction force of the liquid W is large enough to attract the bubbles B floating in the liquid W in the water tank 2 to the vicinity of the water port 8, the bubble collecting member 10 may be omitted.

In this embodiment, the gas-liquid separation pipes 11 and 91 and the gas-liquid separators 51 and 71 are used to suppress the inflow of bubbles B into the submersible pump 7 and the pump 84 as the suction device of the present invention.
Alternatively, although the storage tank 81 is used, the means for suppressing the flow of bubbles into the suction device is not necessarily limited to this. For example, a gas-liquid separation chamber that separates bubbles from liquid is provided at a discharge port of a pump, and bubbles are separated from liquid by the gas-liquid separation chamber. The liquid W in the bubble conduit may be sucked using a suction pump.

Further, in the present embodiment, the shape of the bubble conduit 6 is formed to be substantially L-shaped when viewed from the side. However, the shape of the bubble conduit is not necessarily limited to this. It may be extended spirally, or a bubble pipe may be extended like a mesh in a water tank. That is, by forming the flow path of the bubble B constituted by the bubble conduit in various forms, the decorativeness and visual effect in the water tank can be further improved.

[0057]

According to the aquarium decoration system of the present invention,
In the bubble conduit linearly extended in the water tank, the liquid in the bubble conduit is sucked by the suction device, so that the bubbles released from the discharge member are sucked together with the liquid in the water tank from the water inlet. As a result, it is possible to flow through the bubble channel. Therefore, for example, if the bubble channel is extended in a direction different from the path of the bubbles floating in the liquid, the bubbles flowing in the bubble channel appear as if they are freely floating in the liquid. Can be. By causing the bubbles to flow in the bubble channel as described above, the bubbles floating in the liquid in the water tank can be caused to flow in a direction contrary to the expectation of the viewer. Therefore, due to the unexpected flow of such bubbles,
A person watching the inside of the aquarium can be enjoyed through the wall material of the aquarium, and there is an effect that the interior of the aquarium can be decorated by an unexpected flow of bubbles.
