DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a live fish container used for transporting live fish and other live fish such as fish and shellfish caught in rivers or the sea, or for breeding such live fish. The present invention relates to a live fish container water purification device or a water purification device for purifying sewage.

[0002]

2. Description of the Related Art Heretofore, a water purifying apparatus to be mounted on a live fish container used for transporting live fish and other live fish such as fish and shellfish caught in rivers or the sea, or for breeding live fish, etc. has been described below. Something like was used. (A) To transport the above-mentioned live fish and the like in a state where they are utilized, put the live fish and the like in a container that does not easily spill water, and inject air into the water in the container using an air pump driven by a battery. What is made to be made is generally marketed and used widely.

(B) In addition, in order to transport the above-mentioned live fish and the like while utilizing them, the live fish and the like are sealed in a plastic bag or the like, and oxygen is injected into the plastic bag before being used in an automobile or an aircraft. Transport methods are used.

(C) In order to breed the above-mentioned live fish in an appreciation container or the like, water filtration of the container is carried out by circulating water through a filtration device provided inside or outside, and furthermore, if necessary, outside air. Air or oxygen is injected into water by an air pump or the like.

[0005]

However, the above-mentioned conventional methods generally have the following disadvantages. (A) When oxygen is injected from outside air, the container cannot be sealed, and there is a great risk of water leakage. (B) The method of injecting oxygen into a plastic bag has the disadvantage that once the plastic bag is opened, almost all of the oxygen leaks out and must be injected again.

(C) Further, in the case of transporting both of the above for a long time, the quality of water deteriorates due to excretion of live fish, which causes the drawback that live fish become sick or die. is there.

(D) When water is circulated through a filtering device provided inside or outside for filtering water for the live fish container, the size of the device becomes large. In addition, since outside air or oxygen is injected into the water to supply oxygen to the water, the container cannot be sealed, the noise caused by bubbles rising in the water is large, and the evaporation of the water is large, There is a disadvantage that the humidity rises abnormally.

(E) When seawater is used for a live fish container, when the foam pops, the salt in the seawater also scatters, and the salt adheres to the upper portion of the container, or the seawater in the container. However, there is a disadvantage that the salt concentration is lowered.

The present invention has been made to solve the above-mentioned drawbacks, and has as its object to transport live fish and the like while keeping them alive for a long time, and to view live fish and the like for appreciation. An object of the present invention is to provide a water purification device suitable for a live fish container to be bred. It is still another object of the present invention to provide a water purification device that can be used for purification of wastewater having relatively high fluidity.

[0010]

According to the present invention, in order to achieve the above object, a water purifying device is provided inside or outside the live fish container corresponding to the live fish container containing fresh water or seawater. Inside the container of the water purification device, an aerobic microorganism growing room was provided so that oxygen could be injected into the upper part, and fresh water or seawater of the live fish container was circulated inside the microorganism growing room. It is a feature. Further, the present invention is characterized in that sewage is recirculated and purified in a container with a similar configuration.

At the boundary between the water and the drainage chamber 8, there are mounted perforated partitioning plates 12A and 12B having a large number of small holes 13 formed in the lower part. The aerobic microorganism growing room 10 is provided with a water intake room 7 as shown in FIG.
At the boundary with the drainage chamber 8 are mounted porous partition plates 14A and 14B having a number of small holes 13 formed in the lower part.

As shown in FIG. 2, the aerobic microorganism growing room 10 is configured to partition from the partition plate 11A between the anaerobic microorganism growing room 11 and the middle of the aerobic microorganism growing room 10.
Intermediate partition plates 15A, 15B, 15C and container 1A of apparatus 1
As shown in the figure, two intermediate partition plates 16A and 16B are provided alternately so as to partition from the side plate 1C to the middle of the aerobic microorganism growing room 10.

The three intermediate partition plates 15A, 15A
As shown in FIGS. 2 and 5 to 11, three perforated intermediate floor plates 17A, 17B, each of which has a large number of small holes 13, are provided between B, 15C and the two intermediate partition plates 16A, 16B. 17C is installed in the water to make the aerobic microorganism growing room 10 two-story.
At the center of the perforated intermediate floor plates 17A, 17B, 17C, six partitioning weir plates 18A to 18F slightly protruding upward from the perforated intermediate floor plates 17A, 17B, 17C are provided.
Small holes 13 are formed in the six partitioning weir plates 18A to 18F.

FIG. 13 shows an embodiment of the water intake device 4. This device 4 has an outer cylindrical body 40 having a plurality of small holes 41 formed in the lower part, and a sea surface rubber or the like inside. And an inner cylindrical body 42 to which the filter 43 is attached. Also, the inner cylinder
A handle 44 is provided inside the 42 so as to have a mesh body 45 at the tip which allows the filter 43 to be taken out upward, and a water-blocking cylinder 46 is provided to prevent water leakage between the filter 43 and the handle 44. ing. The filter 43 can be taken out and cleaned by pushing down the water-blocking cylinder 46 to protrude the handle 44 upward and pulling up the handle 44 upward.

Therefore, the water intake device 4 is provided with an arrow a ₁
As shown, the suction of water into the interior of the outer cylinder 40 from the small holes 41, increases as shown by the arrow a _2, as indicated by an arrow a _3, drawn into the interior of the inner tubular member 42, the filter 43 through the discharges downwardly as indicated by arrow a _4.

Next, as shown in FIG. 3 and the like, the drainage device 5 includes a water suction cylinder 50 and a motor pump 51 having a battery therein.
, A water discharge cylinder 52, a horizontal gutter 53, and a water discharge port 54. Since a well-known motor pump with a built-in battery is used, detailed drawings and explanations thereof are omitted.

FIG. 14 shows a container main body 2A equipped with the water purification apparatus 1 of the embodiment of the present invention constructed as described above, and a lid 2
B shows the live fish container 2 made of B. And Figure 1
5, as shown in FIG. 16, inside the anaerobic microorganism growing room 11 and the aerobic microorganism growing room 10, in order to infest a large number of microorganisms such as algae and bacteria, porous stones 60 such as pumice stones are appropriately installed, After the water 70 such as fresh water or seawater is filled in the container main body 2A, if necessary, fish and shellfish such as live fish 80 are added. At this time, the inside of the water purification device 1 is also full. Under this condition, oxygen 90 is injected from the oxygen injection pipe 3 into the oxygen injection chamber 6. As a result, the oxygen 90 flows from the oxygen injecting chamber 6 through the oxygen outflow window 9 into the upper part of the aerobic microorganism growing chamber 10. That is, oxygen 90 is accumulated on the ceiling of the aerobic microorganism growing room 10, and is dissolved in the water 70 flowing below. Live fish 80
When such a substance inhabits inside the container body 2A, the nitrogen-based gas naturally accumulates above the water purification device 1 and the amount of oxygen decreases. In such a case, the illustrated oxygen injection pipe 3
, The gas inside the water purification device 1 is discharged, and oxygen is injected as described above in a state where the water is filled above the water purification device 1.

Next, the operation of the motor pump incorporated in the drainage device 5 will be described. Hereinafter, the operation of the water purification device 1 attached to the live fish container 2 will be described in detail. (1) The container 1A of the water purification device 1 uses the lower portion of the container main body 2A of the live fish container 2, thereby omitting the bottom plate and the side plate 1C of the container 1A, and providing a cover plate below the container 2A. The container 1A can be configured so as to make only 1B.

(2) The oxygen injection pipe 3 uses a rubber tube (not shown) attached to an oxygen cylinder (not shown).
If oxygen is supplied above the container 1A filled with water 70, the oxygen injection pipe 3 as shown can be omitted.

(3) When the motor pump incorporated in the drainage device 5 is operated, the water 70 such as fresh water or seawater in the container body 2A of the live fish container 2 is supplied through the water intake device 4 to take water. Although the filter 43 flows into the inlet 7, the filter 43 provided in the inner cylinder 42 of the water inlet device 4 shown in FIG. 13 may be installed in the water inlet 7.

(4) The water 70 flowing into the water intake chamber 7 is
The water 70 flows into the anaerobic microorganism growing room 11 through the small holes 13 of the porous partition plate 12A shown in FIG. 15, and the water 70 flows into the drainage chamber 8 through the small holes 13 of the porous partition plate 12B. Anaerobic microorganism growing room
The inside of 11 is filled with porous stones 60, so that the flowing water is extremely slow.

(5) On the other hand, the water flowing into the water intake chamber 7
70 flows into the aerobic microorganism growing room 10 through the small holes 13 of the porous partition plate 14A, and a solid arrow A drawn in a waveform in FIG.
_As shown by ₁ , three intermediate partitions 15A, 15B, 15C
And two intermediate partition plates 16A and 16B meandering.

[0028] (6) Then, in meandering indicated by the solid arrow A _1, interlace six partition dam 18A~18F The partition dam 18B, 18D, because the water 70 flows through the bottom of 18F , dashed arrows B _1, B _2, B numerous as indicated by ₃ of 3 like the small holes 13 bored porous intermediate floor 17A in FIG. 14, 17B, 17
Water 70 flows above and below C, and passes below. That is, the water 70 flows while contacting the porous stone 60.

(7) The aerobic microorganism growing room 10
The water 70 flowing into the anaerobic microorganism growing room 11 flows into the drainage chamber 8 through the small holes 13 of the partition plate 14B.
At the same time, the water suction cylinder 50 of the drainage device 5 installed in the drainage chamber 8
It is further sucked in and discharged from the water discharge port 54 of the device 5.

(8) Water 70 in the aerobic microorganism growing room 10
In the flow of water 70, since a large number of porous stones 60 are present on the flow path of the water 70, the presence of the porous stones 60 becomes a resistance to the flow of water, and the water suction cylinder 50 of the drainage device 5 The closer to, the stronger the suction force works. Furthermore, since the suction force from the drainage device 5 is selected so as to be like that, the water surface in the aerobic microorganism growing room 10 has water surfaces C ₁ , C ₂ , C shown by broken lines in FIG. a step is formed as _3. When the water 70 flows by jumping over the six partition weirs 18A to 18F, oxygen 90 existing between the ceiling 70 in the aerobic microorganism growing room 10 is dissolved in the water 70. Is being promoted.
And by the height of the water surface C _1, C _2, C ₃ are different manner, also by the flow of water 70 is to flow bypassing the partition weir plate 18a-18f, present in the space For example, the porous stone 60 described above partially appears on the surface of the water and becomes dry or wet. That is, a wet-and-dry effect is achieved.

(9) In the space between the porous partition plate 14B and the partition weir plate 18F shown in FIG. 12, the above-mentioned porous stone 60 is basically not arranged. The reason is as follows. That is, if a large number of porous stones 60 are present in this space, the porous stones 60 will partially block the holes of the porous partition plate 14B, and when water is taken into the drainage chamber 8 by the drainage device 5, The resistance on the road may be so large that the drainage chamber 8 may not be supplied with enough water to meet the drainage capacity of the drainage device 5. Under such a state, oxygen existing above the porous stone 60 in the drainage chamber 8 passes through the gap where the porous stones 60 contact each other, and
Will be undesirably drawn into. Therefore, oxygen that should have been stored and stayed above the aerobic microorganism growing room 10 passes through the hole of the porous partition plate 14B to the drainage room 8 side, and the water is discharged from the drainage device 5 with water. Will be discharged together. That is, the oxygen that should stay in the aerobic microorganism growing room 10 disappears. This is the reason mentioned above.

(10) In the aerobic microorganism growing room 10, aerobic microorganisms propagate, and the anaerobic microorganism growing room 11
Since anaerobic microorganisms proliferate, when the freshwater or seawater water 70 is circulated in the two microorganism growing chambers 10 and 11, a live fish is produced by the action of the microorganisms in the two microorganism growing chambers 10 and 11. Can be decomposed and purified.

(11) The water discharge port 54 of the drainage device 5
As shown in FIG. 15, it is installed below the level of water 70 contained in the container body 2A. Thereby, there is no noise such as water noise, and the evaporation of the water 70 can be suppressed.

In particular, in the case of seawater, by preventing evaporation of the water 70, so-called “salt dripping” in which salt is deposited near the water discharge port 54 can be prevented. That is, if the water discharge port 54 is installed above the surface of the water 70 and the water 70 falls from above the surface of the water, bubbles are generated on the surface of the water, and the bubbles evaporate at the time of Hajikel. Promoted.
In the case of seawater, salt also splatters, causing "salt dripping".

(12) Although the drainage device 5 has been described as having a battery and a motor pump (not shown) mounted on the motor pump section 51, this is achieved by using an external power supply (not shown) to operate the motor pump. The motor may be driven, or the motor may be installed outside.

(13) Of course, the water discharge port 54 of the drainage device 5 may be installed above the surface of the water 70 if necessary. (14) Although not shown in the live fish container 2 shown in FIG. 14, a well-known cooler device is separately installed so that the temperature of the water 70 in the container body 2A is maintained at a predetermined temperature. You may.

(15) The embodiment shown in FIG.
Although only one container 1A is shown, a plurality of containers 1A may be manufactured and organically combined for use. That is, a plurality of similar containers 1A may be superimposed and water from the drainage chamber 8 of the lower container 1A may be connected to the water intake chamber 7 of the upper container 1A.

(16) Although the container body 2A having the lid 2B shown in FIG. 14 has been described, it goes without saying that a container without the lid 2B may be used. (17) In general, the water purifying apparatus for a live fish container according to the present invention is a so-called independent device having a lid plate 1B, a side plate 1C, and a bottom plate, as shown in FIG. 1 to FIG. It is a box that did. However, as described above, a part or all of the side wall and / or the bottom plate of the live fish container main body 2A (shown in FIG. 14) may be used as a part of the water purification device of the live fish container. That is, the water purifying device for the live fish container is not an independent box, but is submerged in the live fish container and utilizes a part of the live fish container, and as a result, a box is formed. It just needs to be able to accumulate oxygen.

(18) Further, in the case where one or more of the water purifying devices for live fish containers according to the present invention constitute the above-mentioned independent box, the water purifying device for live fish containers is provided. Need not be used by sinking in the live fish container main body 2A. That is, the water 70 in the live fish container main body 2A is disposed outside the live fish container main body 2A, and is circulated through the water purification device of the live fish container via, for example, a hose or the like, and the oxygen 70 is discharged as described above. And may be arranged so as to be returned to the inside of the live fish container main body 2A after being brought into contact with the main body.

[0040]

As is apparent from the above description, the present invention has the following remarkable effects.

(B) Unlike the conventional case, since air or oxygen is not always injected from the outside air, the container can be sealed, so that there is no fear of water leakage and long distances in automobiles and the like can be achieved. Easy to carry.

(B) Conventionally, in the case of long-time transportation, the quality of water produced by excretion of live fish deteriorates, which often causes the live fish to weaken or die. Since the water in the container is circulated through both the anaerobic and aerobic microbial growth chambers, the excretion of the live fish and the like is decomposed and purified by the action of the microorganisms. In some cases, live fish are weak,
Dying can be completely prevented.

(C) It goes without saying that the present invention can be used not only in the case of transporting live fish as described above but also in a live fish tank for watching live fish and the like in a general room. Also in such a case, it is not necessary to replace the water in the live fish tank at all or at least for one year or more.

(D) In particular, the water purification apparatus according to the present invention has an aerobic microorganism growing room together with an anaerobic microorganism growing room, and stores oxygen between the lid plate and water in the aerobic microorganism growing room. The turbulence is created by intervening porous stones, porous intermediate floor plates, porous partition plates, and partition weir plates while meandering the flow of water in the room, so that oxygen can be dissolved efficiently. . As a result, it is not necessary to replace the water in the live fish container body for, for example, one year or more (of course, it is necessary to periodically replenish oxygen as needed).

(E) The above-mentioned water purifying device was invented in consideration of use in combination with a live fish container. The water purifying device is designed to accumulate oxygen in the container. Therefore, it can be used as a purification device for general water or sewage, apart from the usage mode in which it is used in combination with a live fish container.

(F) Needless to say, the function of the water purifying apparatus used for live fish is also effective for purifying sewage having relatively high fluidity. (G) In the above-described water purification device, the water purification device itself is provided with a water intake device and a drainage device. However, a water purification device in a state where the water intake device and the drainage device are removed from the water purification device itself described above,
Sewage is sent from the stored water tank to the water purification device,
After being brought into contact with oxygen in the water purification device, the water may be sucked out of the water purification device and returned to the original water tank.
That is, the water purification device may be used simply as a contact place between water and oxygen.
