Description

  The present invention relates to a non-sealed water tank.

  Water tanks are roughly divided into sealed and non-sealed types. As the sealed water tank, a water tank used as a raw fish transport device can be exemplified, and a closed water tank equipped with an adsorption tank for adsorbing and removing carbon dioxide by circulating a gas in the water tank is disclosed (Patent Document 1). As other sealed water tanks, water tanks used for exhibitions other than fish breeding can be exemplified, and closed water tanks using water mixed with antiseptic / algaeproofing agents and antifreeze liquids are disclosed (Patent Document 2). ). There are many types of non-sealed water tanks, but in order to use them for breeding fish, it is preferable to supply oxygen by blowing air into the water tank, and generation of bubbles is also preferable in terms of aesthetics. However, when air is blown in, the water surface is lowered due to the evaporation of water, so it is necessary to replenish water. In particular, when the water tank is thin, since the area of the water surface is small, the liquid level drop due to water evaporation becomes remarkable. Therefore, it is highly desirable to take measures to prevent water surface deterioration.

For this reason, it was not necessary to replenish water or the frequency could be greatly reduced.

The present invention will be described below with reference to the drawings as appropriate.
The present invention is a non-sealed type provided with a water tank main body and air blowing means for sucking air having a relative humidity of 60% or more (hereinafter also simply referred to as “humidified air”) and blowing this air into the water in the water tank main body. It relates to the aquarium. If the temperature of the air to be sucked is different from the temperature of the air to be blown, the relative humidity changes, but in the present invention, the relative humidity of the air to be sucked is defined.
FIG. 1 is a schematic front view showing an outline of a water tank according to the present invention. The non-sealed water tank 1 of the present invention includes a water tank body 2, water 3 stretched on the water tank 2, and air blowing means for sucking air having a relative humidity of 60% or more and blowing the air into the water 3 in the water tank body 2. Yes. The air blowing means will be described later.
The relative humidity of the air to be sucked is preferably 80% or more, more preferably 90% or more, and particularly preferably 95% or more.

Moreover, the water 3 stretched in the water tank main body 2 may contain an aqueous organic compound compatible with water, if necessary. Examples of the aqueous organic compound include ethylene glycol, polyethylene glycol, and glycerin. The content is preferably less than 50% by weight, more preferably 20% by weight or less, particularly preferably 10% by weight or less, and particularly preferably not containing such an antifreeze component.
The water used in the present invention is preferably tap water or well water, more preferably water that has been sterilized by boiling. Also preferred is water that has been ion exchanged to reduce calcium. Preservatives, antifungal agents, and the like can be appropriately added to the water used in the present invention.

The shape of the water tank body 2 may be a cylindrical shape, but is preferably a rectangular parallelepiped. At least one of the five surfaces (excluding the upper surface) constituting the rectangular parallelepiped is light transmissive, and it is preferable to use a substantially transparent plate (transparent plate). “Substantially transparent” means that the average transmittance in the visible region is 90% or more. More preferably, the two opposing surfaces are substantially transparent.
When the water tank main body is a rectangular parallelepiped, the width, height, and depth can be freely selected. The aquarium body of the present invention is preferably thin with an outer dimension of the depth of 20 mm or more and 200 mm or less, and more preferably 30 mm or more and 100 mm or less. As the water tank main body becomes thinner, the area of the water surface becomes smaller and the water surface lowers more conspicuously, so the effect of the present invention becomes more effective.
Although the width | variety of a water tank main body can be selected arbitrarily, 60 cm or more is preferable and 70-180 cm is more preferable. Although height can also be selected arbitrarily, 30 cm or more is preferable and 50-120 cm is more preferable.
A glass plate can be preferably used as the transparent plate of such a large aquarium. The thickness of the glass plate is preferably 3 to 8 mm, more preferably tempered glass with a protective film for preventing scattering. Moreover, the transparent board which affixed the scratch-resistant film of surface hardness 5H or more to organic glass plates, such as PMMA, can also be used, In this case, although thickness can be selected suitably with water tank capacity | capacitance, it is preferable to set it as 3-15 mm.
The thin water tank described above can be used for incorporation into a panel device. The module (functional unit, width) of the panel device is preferably 90 to 270 cm, and more preferably 90 to 180 cm.

  The air blowing means includes an air suction pipe that sucks humidified air from a humidified air source, a pump that sucks and discharges humidified air (air suction / discharge pump), and an air blower pipe that blows humidified air from the air suction / discharge pump. The supply source of the humidified air may be in the water tank body or outside the water tank body as long as it can supply air having a relative humidity of 60% or more, but is preferably in the water tank body. As the air suction / discharge pump, various commercially available products such as a diaphragm pump can be used.

Preferred embodiments of the present invention are described below.
Two preferred sources of humidified air can be exemplified. As one example, as illustrated in FIG. 1, an unsealed lid 31 is preferably provided on the upper side of the water tank body 2, and humidified air inside the gas phase 5 between the water surface and the lid is supplied as a supply source. It is what. The other one is provided with humidified air generating means 12 in the water tank main body 2 or outside the water tank main body 2 as illustrated in FIG. 6, and this is used as a supply source of the humidified air. The former method is simple in that it is not necessary to provide a source of humidified air separately from the water tank body.

As one embodiment of the present invention, the air blowing means is connected to an air suction / discharge pump, a water tank body having a non-sealed lid, one end for sucking air between the water surface in the water tank body and the lid, and the pump. A non-sealed water tank provided with an air suction pipe having the other end and an air blowing pipe having one end connected to the pump and the other end for blowing air into the water in the water tank body will be described.
As shown in FIG. 1, the water tank 1 includes an air intake / exhaust pump 11 above the water tank body 2. An air suction pipe 13 for sucking humid air in the gas phase 5 in the water tank body 2 is connected to the air suction / discharge pump 11. The air intake / exhaust pump 11 is connected to air blowing pipes 15 and 17 for blowing air from the air intake / exhaust pump 11 to the water 3 stretched on the water tank body 2. An unsealed lid 31 is provided on the water surface of the water 3 stretched inside the water tank body 2. The air suction / discharge pump 11 sucks humidified air between the water surface and the non-sealing lid 31, and further blows this overhumid air into the water 3 through the air suction / discharge pump 11.

The non-sealed lid 31 provided on the upper part of the aquarium body 2 can be, for example, a drop lid placed on a frame with a cutout provided on the inner side of the upper part of the aquarium body. The lid 31 has water tightness enough to prevent the water 3 from jumping out of the water tank body 2 even when the water surface is disturbed by vibration applied to the water tank body 2. When the gas phase 5 in the aquarium body 2 becomes negative pressure, the flow of air from the outside of the aquarium body 2 to the gas phase 5 through the gap between the lid 31 and the frame on which these are placed is prevented. There is no unsealed type.
The air blowing pipes 15 and 17 are water-resistant pipes used for blowing humidified air, and regardless of the material thereof, metal pipes, water-resistant synthetic resin tubes and the like can be widely used. Examples of the material of the air blowing tube include a hard tube or a flexible tube made of polyethylene, polypropylene, polyvinyl chloride resin, silicon resin, etc., a copper tube, and a stainless tube.

The water tank 1 of the present invention is a non-sealing type, and even when humidified air is blown into the water 3 in the water tank 1, a structure in which air can enter and exit from the upper surface of the water tank body 2 into the water 3 stretched on the water tank body 2. Have. For this reason, air can enter the inside of the water tank main body 2 through a gap between the lid 31 provided on the upper inner side of the water tank main body 2 and the frame fixed to the water tank main body 2. For this reason, even when aquatic animals such as fish are bred in the aquarium or when aquatic plants are grown, oxygen and / or carbon dioxide required by these animals and plants can be taken into the aquarium 1.
In the present invention, “air” is not limited to a gas having an average composition in the atmosphere, but also includes a gas in which the content of oxygen and / or carbon dioxide is increased or decreased as necessary.
The non-sealed water tank 1 of the present invention has such a degree of sealing that even when oxygen is consumed in the water tank 1, the dissolved oxygen amount of the water 3 in the water tank 1 can maintain a value of 80% or more of the equilibrium amount. It means having. The dissolved oxygen concentration can be measured with a commercially available dissolved oxygen meter (such as Sato Corporation). By providing an appropriate gap between the lid 31 and the frame of the water tank main body 2, a non-sealed type can be obtained.

When fish and the like are not raised in the aquarium, it can be used as a sealed aquarium by sealing the lid with a frame fixed to the aquarium body. In this case, tap water or well water can be used as the water to be put in the water tank, and it is preferable to use after sterilization by boiling. Moreover, ion-exchange water can also be used as it is, and it is also preferable to sterilize by boiling as needed. By reducing calcium ions in water by ion exchange, generation and growth of mold and algae can be significantly suppressed. It is preferable not to use antifreeze that promotes the generation of mold and algae for the water in the aquarium. You may use a fungicide or a fungicide together with the water of a water tank.
Also in the case of a sealed water tank, a configuration similar to that of a non-sealed water tank can be adopted except that the sealing degree of the lid is different.

In the above embodiment, the water tank 1 plays the role of offsetting the moisture evaporating from the water surface by bubbles rising in the water by blowing humidified air into the water 3 in the water tank body 2, and the water surface is substantially at a certain level. Or has an effect of significantly suppressing the decrease.
According to an example of an actual measurement result that will be described later as FIG. 3, as compared with a case where indoor air is blown as it is, an embodiment of the present invention is a case of a water tank with an unsealed lid that blows in humid air between the lid and the water surface. The water evaporation could be reduced to 1/5 to 1/10.

In the water tank 1 of the present invention, the air suction / discharge pump 11 is disposed above the water tank body 2 in the vertical direction. It is preferable that the air suction pipe 13 is disposed horizontally or vertically upward from an end portion inside the gas phase 5 of the water tank body 2 toward the pump. Since the air suction pipe 13 sucks humid air above the water surface, if there is a portion where the suction pipe is cooled to a temperature lower than the dew point, there is a tendency that condensation occurs on the inner wall of the pipe. For this reason, when the air suction pipe 13 is arranged monotonously downward from the air suction / exhaust pump 11 or at least horizontally to the gas phase 5, moisture condensed inside the air suction pipe 13 flows into the air suction / exhaust pump 11. Can be prevented. In this case, even if there is a water droplet condensed on the inner wall of the air suction pipe 13, it can return to the water tank body 2.
The air intake / exhaust pump 11 is moderately overheated by its operation and tends to prevent dew condensation by heating the air intake pipe 13 connected thereto by heat conduction.

With reference to FIG. 2, the specific aspect of the air suction pump 11 for inhaling the humidified air in the gaseous phase 5 in the water tank main body 2 and blowing it into the water 3 in the water tank main body 2 is illustrated.
In FIG. 2, an air suction / discharge pump 11 includes a sealed tank 11a having an air suction port 11b and an air discharge port 11c, and is disposed in the sealed tank 11a. The air suction / discharge pump 11 includes an air discharge port 11e and sucks air from the air suction port 11b. A diaphragm pump 11d that discharges the air to the air discharge port 11e of the air intake / exhaust pump 11, and a connection means 11f that connects the air discharge port 11e and the air discharge port 11c.
In the above example, the diaphragm pump 11d provided with the air discharge port 11e marketed for household water tanks can be used as the diaphragm pump 11d. In a commercially available diaphragm pump, air is often sucked through a vent provided in a resin casing of the pump, and a dust filter is often provided at the vent. Such a diaphragm pump can use only the diaphragm pump main body by removing the resin casing.

As shown in FIG. 2, a sealed tank 11a having an internal capacity capable of accommodating such a diaphragm pump 11d and having an air suction port 11b and an air discharge port 11c is first prepared. Next, a diaphragm pump 11d having an air discharge port 11e is disposed in the sealed tank 11a. The diaphragm pump 11d housed in the sealed tank 11a sucks air sucked from the air suction port 11b of the sealed tank 11a into the diaphragm pump 11d and discharges this air to the air discharge port 11e. If connecting means 11f for connecting the air discharge port 11e to the air discharge port 11c of the closed tank 11a is provided, the humidified air in the gas phase 5 shown in FIG. 17 can be used as an air suction / discharge pump that blows water 17 through water 3. The connecting means 11f may be a direct connection other than using a connecting pipe as shown.
As the diaphragm pump, it is preferable to use a model having an output corresponding to the water depth of the water tank body.
In addition, by housing the diaphragm pump 11d in the sealed tank 11a in this way, an effect of blocking the vibration and noise of the diaphragm pump 11d from the tank can be obtained.

  In addition, by providing a heating source in the air suction / discharge pump 11 and heating the humidified air blown into the water 3, the water temperature of the water 3 can be raised and adjusted to a water temperature suitable for breeding tropical fish.

The present invention depends on the amount of water and the depth of water in the water tank, but is an air suction / discharge pump having a discharge depth of 1 to 10 L / min when the discharge air amount is 60 cm, preferably air having a discharge amount of 1 to 3 L / min. An intake / exhaust pump can be preferably used. Such a product can utilize a commercial item. As commercial products, Nα-series (including Nα-6000, manufactured by Nisso Corporation, 1-6 L / min per discharge), X202 air pump manufactured by ADEX CO., LTD. An example is a 1000 air pump. The amount of air blown into the water tank 1 can be adjusted by a screw cock or pinch cock attached to the outside of the air blowing pipes 15 and 17.
As another aspect of the air suction / discharge pump, a diaphragm pump having an intake pipe and an exhaust pipe can also be used.

With reference to FIG. 3, an example of the water level fall in the water tank of this invention is shown.
In FIG. 3, square points are measurement points indicating a decrease in the water level in the water tank of the present invention. On the other hand, a round point is a measurement point which shows the fall of the water surface in the water tank of a comparative example.
This measurement example shows the effect of the water tank of the present invention when a water tank having a water depth of about 60 cm, a width of about 80 cm, and a thickness (outside dimension) of about 5 cm is used. Compared to the case where indoor air without operating the air conditioner is blown as it is in the late autumn, as an embodiment of the present invention, in the case of a water tank with an unsealed lid that blows humidified air between the lid and the water surface, the water evaporation rate Can be reduced to 1/5 to 1/10. If the sealing degree between the frame fixed to the water tank body and the drop lid is increased, the water evaporation rate can be reduced to 1/20 or less.

In the water tank of the present invention, the air blowing tube can be connected to a foam generating device or a water circulation device.
As shown in FIG. 1, in the water tank 1, the air blowing tube 15 is connected to the other end of the foam generating device 21 provided with a fine hole and closed at one end. The air blowing pipe 17 sends air into the bottom side hollow pipe of the hollow pipe 23 arranged almost vertically in the water tank body 2 and circulates the water 3 in the water tank body 2 as the generated bubbles rise. Connected to a water circulation device.

  FIG. 4 is a partially enlarged cross-sectional view of the upper portion of the water circulation device. The air blowing tube 17 is disposed beside the hollow tube 23, and is inserted into the hollow tube 23 from the lower end portion 17A of the air blowing tube to blow air as shown in FIG. As the foam blown out in the hollow tube 23 rises, the water 3 in the water tank body 2 also rises, and is provided at the upper part of the hollow tube 23 and is bent above the water surface. It falls from the part 23A to the water surface and circulates.

It is also possible to adjust the temperature of the water 3 in the water tank body 2 by arranging a heating source or a cooling source in series with or parallel to the air suction / discharge pump 11 in the passage of the intake / exhaust air.
For example, when the room temperature is 23 ° C., it is preferable to heat the water 3 when the tropical fish is bred in the aquarium 1, and it is preferable to cool the water 3 when the fish is a seawater fish. For temperature control near room temperature, a heating means and a cooling means may be used in combination.

With reference to FIG. 5, one embodiment of the water tank provided with the air heater will be described.
The overall configuration of the water tank 1 shown in FIG. 5 is substantially the same as that of the water tank 1 shown in FIG. The difference is that the copper air blowing pipe 18 is used and that the outer periphery of the copper air blowing pipe 18 is heated by the band heater 19 at a portion relatively close to the water surface. By external heating of the copper air blowing pipe 18, heat conduction to the copper air blowing pipe 18 thrown into the water, and blowing of the heated humidified air to be blown, the temperature of the water 3 is kept at room temperature or higher. be able to. In order to adjust the temperature, the electric output for heating the band heater 19 may be changed using a temperature controller (not shown). You may heat-treat the outer periphery of the band heater 19. The copper air blowing pipe 18 may be located closer to the water tank than the band heater 19, and a synthetic resin air blowing pipe may be connected to the air suction / discharge pump 11 side.
Moreover, since the copper air blowing pipe | tube 18 introduce | transduced in water is heated, the water flow which raises the circumference | surroundings is produced. Water in the water tank can be circulated by this rising water flow. In the case of a water tank with a small depth, circulation of water by convection of a heated copper air blowing pipe 18 is particularly effective.

FIG. 6 is a conceptual schematic view of an embodiment in which the supply source of humidified air is provided in the water tank body or outside the water tank body.
In the non-sealed water tank 1 shown in FIG. 6, the air blowing means is connected to the air intake / exhaust pump 11 and one end for sucking humid air generated by the humid air generating means 12 provided outside the water tank body 2 and the air intake / exhaust pump 11. The air suction pipe 13 having the other end and the air blowing pipes 15 and 17 having one end connected to the air suction / discharge pump 11 and the other end for blowing air into the water 3 in the water tank main body 2 are provided.
As the humidified air generating means, in addition to the foam generating device 21 illustrated in FIG. 6, an ultrasonic water fog generating device or a water heating steam generating device can be illustrated.
Also in the non-sealed water tank shown in FIG. 6, as shown in FIG. 1, various bubble generating devices and / or water circulation devices can be connected to the air blowing pipe.

The structural example of the water tank main body which can be used for this invention below is demonstrated.
The water tank main body used for this invention can adhere | attach the peripheral part of two plate-shaped bodies which oppose via a spacer frame material. It is preferable that this water tank main body has a sealing material on the outer peripheral side of the spacer frame material, and the sealing material is formed up to the outer periphery of the end surface of the plate-like body. Moreover, it is preferable that the fixing member is inserted in the peripheral part outer side of a plate-shaped object. The depth (outside dimension) of the water tank body is preferably 20 mm or more and 200 mm or less. It is preferable that the spacer frame material has a U-shaped cross section, the spacer frame material and the plate-like body are bonded with a silicon adhesive, and the sealing material is butyl rubber.
Further, two horizontal spacer frame members and two vertical spacer frame members are arranged so as to form a rectangle at the peripheral edge of the two rectangular plate-like bodies, and the four spacer frame members are formed in the rectangular shape. It is preferable that the water tank is an aquarium in which an opening is formed in one of the horizontal spacer frame members. Moreover, it is also preferable that the fixing member is inserted into the four sides of the plate-like body, and that the fixing member is provided with an opening outside the spacer frame member having the opening or that the fixing member is not inserted.
Hereinafter, the water tank main body which can be used for this invention is demonstrated using FIG. Hereinafter, the same reference numerals are used to indicate the same objects.

FIG. 7 is a schematic perspective view showing an example of a water tank main body that can be used in the present invention.
In FIG. 7, a is the depth (thickness) outside the aquarium body, b is the width outside the aquarium, and c is the height outside the aquarium.
In the water tank body 100, the peripheral portions of two opposing plate-like bodies 102, 102 ′ are bonded via a spacer frame member 104.
Moreover, in FIG. 7, the sealing material 112 is provided on the outer peripheral side of the spacer frame member 104, and the water tank body 100 is sealed in a watertight manner. Further, the sealing material 112 is formed up to the outer periphery of the end surface 110 of the plate-like bodies 102 and 102 ′.
In FIG. 7, a fixing member 120 is fitted on the outer peripheral edge of the plate-like bodies 102, 102 ′ of the water tank main body 100. The fixing member 120 may be a single member that is continuous with both sides of the water tank body 100, the bottom surface, and the top surface.

  The water tank main body shown in FIG. 7 can be suitably used particularly for a thin water tank. Since this aquarium body can be manufactured without an assembling operation by putting a human hand inside the aquarium like a conventional aquarium, it is suitable as a thin aquarium body that is difficult to assemble from the inside. The assembly work broadly means work required at the time of manufacturing the water tank, such as bonding work, reinforcement work, and sealing work.

  The width b of the water tank main body is not particularly limited and can be selected with a desired size, but is preferably 30 to 180 cm, and more preferably 60 to 120 cm. By setting the width b of the water tank body within the above range, it is preferable because the water tank has excellent strength.

Here, the width, depth, and height of the water tank are all expressed in external dimensions.
A water tank with a small depth of the water tank body, in other words, a water tank with a large aspect ratio, is difficult to work from the inside of the water tank as described above, and it has been difficult to obtain a highly water-tight water tank by the conventional method. In the present invention, a water tank body having the above aspect ratio is particularly suitable.

Moreover, it is also preferable to affix an anti-scattering film on the surface (any surface or both surfaces, preferably the outer surface) of the plate-like body. Affixing the anti-scattering film is preferable because it can improve the safety when the plate-like body is broken and can improve the strength of the plate-like body. In particular, it is preferable to apply an anti-scattering film because damage caused by glass fragments can be reduced when a human body or an object collides with the glass or when the glass is broken due to distortion of the glass due to an external force such as an earthquake. . Examples of the scattering prevention film include a polyester film or a polyvinyl chloride film coated with a pressure sensitive adhesive, and a polyester film is more preferable. Further, the outer surface of the scattering prevention film may be further subjected to a hard coat treatment.
Various anti-scattering films are on the market. Specifically, CLM-2HC and CLM-2X (manufactured by Sanki Co., Ltd.) can be exemplified, and CLM-2HC (hard coat treatment film) is particularly preferable.
Further, the outer surface of the plate-like body can be subjected to an antifogging process, and the inner surface of the plate-like body can be subjected to an anti-algae treatment, an anti-fungal treatment, or the like.

  Moreover, the water tank of this invention can be used in order to incorporate in a panel apparatus.

The water tank of the present invention can be used for various applications and is not particularly limited.
For example, an aquarium for breeding ornamental fish or an aquarium for ornamental can be provided by arranging underwater plants. Moreover, it is also possible to generate bubbles from the lower part of the water tank to make an interior decoration. As an interior decoration, indoors in which preservatives and coloring agents are added to water or water-miscible aqueous solvents (for example, glycerin, ethylene glycol, etc.) as necessary in the water tank to generate bubbles in the water tank. A decorative tool can be illustrated. It is also preferable to apply illumination appropriately.

It is preferable to arrange illumination or provide an air supply pump, a water circulation pump, or the like as appropriate according to the intended use.

In particular, the aquarium of the present invention can be a thin and large aquarium, and is preferably used for being integrally attached to the panel device.
The panel device can be used as a partition or as a decorative wall.
The water tank attached to the panel is at least one selected from the group consisting of stirring means, air or oxygen supply means, carbon dioxide supply means, drainage means, bait supply means, lighting means, water exchange means, and water purification means. It is preferable to comprise.
Said means can be suitably selected from the various means currently used for the well-known water tank.
