Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter used for breeding tropical fish, crayfish and aquatic animals.

[0002]

2. Description of the Related Art Conventionally, when breeding water organisms in a water tank, upper filtration in which a filtration tank is placed on the upper surface of the water tank, external filtration that is placed below or beside the water tank, and internal filtration that is placed in a breeding tank. Is commonly used.

[0003]

As shown in FIG. 8, the conventional filtration apparatus cannot cope with the height H as shown in FIG. Was. That is, only the strong motor can be used for the upper filtration placed on the water tank. Also
Fig. 8: Internal filter shaped like an alcohol lamp
(B), etc. show that the filter is in the water tank,
Chemical filtration is good, but physical filtration, which removes trash directly, has drawbacks. Moreover, when the supply of energy such as air is stopped, the garbage that has only been sucked is immediately separated from the filter medium and returns to the water tank, so there was a drawback that physical filtration did not work well like top filtration. . In other words, there are many drawbacks regarding the removal of trash out of the breeding tank. That is, there is a drawback that garbage is always in the aquarium. In the conventional case, the only way to request physical filtration is to use upper filtration or the like with a strong motor. Other filtration devices, such as bottom filtration, have similar disadvantages.

In view of the above-mentioned drawbacks of the prior art, the present invention considers a method capable of sufficiently performing physical filtration even with a weak motor or a weak lift force of circulation by air, that is, a filter tank floating on the water surface. Was. It is an object of the present invention to provide a filtration device which can sufficiently perform physical filtration even with an air lift or pumping by a weak motor, and which is completely the same as the upper filtration. Another object is to provide a suction unit for collecting fry and shrimp, and to make this possible with low energy. These and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only and do not limit the scope of the present invention.

[0005]

In order to achieve the above object, the present invention uses a low-energy air lift or weak energy from a weak motor to provide a filter tank floating on the water surface and a filter tank having a small height from the bottom. Filtration by a perforated plate on which the floating filter medium is placed, a pumping pipe that passes through both the filter medium, the filtration tank and the perforated plate, a pumping pipe of a different diameter that is slidably connected to this pipe, and a suction unit provided at the tip of the pipe. Make up the device.

[0006] For the purpose of collecting fry and shrimp, the suction section is enlarged, and the suction section uses the habit of gathering moving fry and fry shrimp. A swaying thread or hair is installed in the living space in the wide suction section, the lower part of the suction pipe communicates with this suction section, and a large suction hole of this pipe and a large number of suction holes are provided on the outer wall of the large suction section. The configuration was such that the distance from the hole was sufficient. Also, if the suction hole on the outer wall of the suction unit is tapered so that the outlet goes into the inside, it will be very difficult for shrimp and the like to enter the space inside the suction unit.

[0007]

[Function] In the filter tank floating on the water surface configured as described above, the water level in the breeding tank matches the water level in the filter tank, so the pumping head is low, so low-energy air lifts and motors with weak power are used. But it will be possible to pump up enough water. This is a filter tank made of a material that floats on the surface of the water, and it sinks appropriately under the weight of the filter material (such as gravel). Therefore, it can be said that there is a space between the water surface and the bottom of the filter tank to fill the filter material. Because it is happening.
Also, in simple terms, since it is placed on the water surface in the breeding aquarium rather than the upper filtration placed on the breeding aquarium, it is at a very low position from the base, so that the pumping lift was extremely reduced. In order to accommodate the difference in the depth of the breeding aquarium, a double pipe that can slide was considered. In addition, the suction part in the case of fry shrimp and fry collection,
Increase the distance between the suction hole provided on the outer wall of the suction part and the suction hole of the pumping pipe to provide a living space for juvenile shrimp and fry. By utilizing the habit of gathering, and by devising a tunnel with a narrow outside and inside, which is provided on the outer wall, the shrimp that entered have been prevented from coming out again. In addition, a strong motor pump for collecting shrimp and fry will be caught in the screen and die. According to the airlift, there is no worry.

[0008]

FIG. 1 shows a first embodiment of the present invention.
One of the points of the present invention is to use a filtration tank 1 made of a material floating on water. As a result, it does not sink even if it is covered with water. Due to the balance of the weight of the filter media 2 (gravel etc.), the filter media 2 and the filter media 4 thereon are positioned lower than the water level 3 of the breeding aquarium.
(Wool) can be pressed down.
Then, since the water level 5 in the filtration tank 1 necessarily coincides with the water level 3 in the breeding aquarium, a large amount of water lifted by the power of the air is smoothly discharged from the outlet 6. This is because the outlet 6 is in water lower than the water level 5. In this embodiment, the air 9 blows up the air 9 from the air stone 8 upward. The water flow 10 is generated by the force of the upward mill 9, and the water is carried from the discharge port 6 into the filtration tank as shown by an arrow 11. Such an air lift hardly pumps water when the outlet 6 is above the water level 5. The first point of the present invention is that the filtration tank 1 is settled and the outlet is lowered into water. Since the filter media 2 and 4 have been set below the opening of the filter in advance, as shown in FIG. The water 12 that has been pumped into the filtration tank 1
It is filtered while passing through the filter material (such as wool) 4 and gravel 2, passes through the hole 17 of the filter material plate 16, passes through the hole 18 at the bottom of the filter tank 1, and enters the breeding tank 13. . Breeding tank 13
A suction hole 15 is provided in a suction unit 14 for sucking dirty water therein. 19 is an air hose. Reference numeral 20 denotes a hole for fixing the air hose. Reference numeral 21 denotes a cut for attaching and detaching the air hose. Saran's Ami (Amido Ami) 2
2 may be laid. The pipes 23 and 24 for pumping water into the filtration tank 1 are slidable with respect to each other, so that they can correspond to the depth of the water tank or the pond. 25,2
Reference numeral 6 denotes upper and lower stoppers for fixing and opening the filtration tank 1 to the pipe. Suction unit 1 for sucking dirty water in breeding tank 13
Reference numeral 4 may be fixed to the pipe 24 or detachable. Since the filtering device of the present invention floats on the water surface due to the buoyancy of the material, the components below it hang down so that they are very stable in the water tank.

[0009]

Second Embodiment FIG. 2 shows a second embodiment of the present invention. Since the drawings are complicated, the same reference numerals are omitted. In addition, overlapping description will be omitted. A feature of the second embodiment is that the upper filtering device floating on the water surface of the first embodiment has a suction unit 27 for collecting juvenile shrimp (fresh shrimp) and juveniles. Filtration by an air lift is convenient because there is no screw like a motor, so that shrimp and shrimp are not swallowed and die. In addition, since the filtration device of the present invention enables the upper filtration by an air lift, the refuse in the breeding tank is completely removed to the outside unlike the internal filtration. Air lifts are very economical because they have lower energy than motors. This was realized because the filtration tank 1
It is not an exaggeration to say that the idea of floating deeply down (28) has solved everything.

The second embodiment will be further described. The suction unit 27 was designed to have a large bottom area and a large volume so as to have a sufficient space for shrimp and fry. The suction hole 29 provided on the outer wall of the suction section 27 is set so as to be narrower as it goes in, so that it is difficult to go out once again. A mere hole is also included in the present invention. Juvenile shrimp (child of shrimp) grow by grabbing on the beard-like feet under the parent's tail.
It is also an important point of the present invention that the apparatus is installed so as to fluctuate due to the water flow or the vibration of the filtration tank 1 due to the water. The suction hole 31 of the pipe body floats slightly from the suction part bottom surface 32,
Juvenile shrimp and fry can be pumped into the filtration tank 1. The yarn 30 is attached to a band 33 via a yarn bundle 34. Outer pipe 2 of band 33
4 is firmly attached to the outer wall. The suction unit 27 has a screw-type lid 35, and the shrimp and fry that have not moved to the filtration tank 1 are collected by taking the lid 35. The upper surface of the lid 35 has a through hole 36 through which the pipe 24 penetrates, and this hole is slightly larger so that the pipe 24 can move a little. Stopper (3
7, 38) are given a play slightly away from the thickness of the upper surface of the lid 35. Thereby, the string 30 fluctuates favorably. Although the suction section 27 of the present embodiment is shown as being transparent, an opaque case is also included in the present invention.
Even if it is opaque, the fluctuation of the inner string 30 from the suction hole 29 can be seen as shrimp, so it is effective even in opacity.

FIG. 3 is a perspective view showing the overall image of the second embodiment so that it can be easily understood. It should be noted that the ideas of the embodiments are interchangeable.

FIG. 4 briefly explains where the important significance of the present invention lies in that it has low energy (economic effect) such as an air lift and a weak motor, eliminates the drawbacks of the conventional upper filtration, and incorporates only the advantages. I do. The significance is the filtration tank 1
Into the breeding tub until the outlet 6 enters the water (arrow 3
9) It is possible to completely move the garbage in the breeding tank outside the breeding tank, which is an advantage of the conventional upper filtration with low energy (air pump). Since the conventional air pump was used only for internal filtration, garbage was always in the breeding aquarium. Even if it was removed in one place, it was still in a breeding aquarium, so it was not a good environment for bred animals. The fact that this is the same as the advantage of the upper filtration itself can be said that the present invention is a revolutionary filtration device.

[0013] The filter of the present invention, which gathers only the advantages of the conventional internal filter and the upper filter, has great significance in that it can sink to a certain position and still float. Since the filter material is set below the discharge hole 6 in advance,
It is only necessary that the discharge hole 6 enters the water. It is best that the material of the filtration tank 1 itself float on water. Otherwise, an airbag (floating bag) 40 may be provided.
A method of attaching a depression or the like to the outer wall of the filtration tank 1 and attaching the filter tank 1 like a band with elasticity can be considered. The same effect as using a material that floats on the water surface can also be obtained by a method of making it hollow and sealing it. The important thing is that some water does not sink. It should be noted that the present invention also has the convenience of using a filter medium to adjust the set position where the filter medium 2 can be floated while keeping the downward direction (arrow 39) constant by using gravel or the like. As described above, the filtration device based on the new concept of filtration above the water surface completely realized the filtration of the upper portion of the air lift. Since the garbage in the breeding tub is completely discharged outside the breeding tub, the environment for the creatures in the breeding tub can be said to be in the best condition. And low energy was realized.

[0014]

Third Embodiment FIG. 5 shows a third embodiment. In the third embodiment, the method of discharging water from the filtration tank of the water level upper filtration device of the present invention is determined by a falling water pipe 41 and an overflow pipe 4.
2 is performed. Others are the same, and the description is omitted.

FIG. 6A is a view showing that the water level difference h is not possible even when the air lift 43 is used for the upper filtration of the conventional concept.

FIG. 6 (b) shows that the filter tank of the present invention cannot be pumped by the height h when the filtration tank is simply floated. Therefore, the present invention is reduced, and
It can be seen that the subtle idea of leaving floating power has important significance.

FIG. 7 (a) shows an example of the use of the present invention. The filter tank 1 is stabilized by the balance between the force of holding down the lower surface 45 of the eaves 44 of the water tank (breeding tank) and the floating force. Is the way. FIG. 7 (b) shows a shallow costume case 4
An example in which No. 6 was used for a breeding tank was shown. The upper figure is an enlarged view of the filtration tank unit 1 in the lower figure. The filter device of the present invention is designed to be bulky, and the weight of the gravel 2 (filter material) is used to balance the sinking and the floating force of the filter tank 1, lower the filter tank 1 and place the discharge hole 6 in water. An example was shown. Even in the garment case 46 and the like, a new concept of the upper filtration and the water level upper filtration device can be used.

Although the above-mentioned water level upper filtration device of the present invention has been manufactured on several trials and used by us, it has achieved an epoch-making activity with the economic effect of the air pump and the power of the upper filtration.
It is the one that has been applied this time after experimentation. It was also found that even if the outlet 6 rises by about 1 to 2 cm from the water level, the effect is completely the same as that of the upper filtration, with a slight decrease in the amount of water. This is based on the principle of the present invention in which the filter tank is floated while being lowered near the water surface. This is due to the filtration tank 1 of the present invention, which does not sink even when covered with water.

[0019]

As is apparent from the above description, the following effects can be obtained in the present invention. (1) Use a material that itself floats on water, or provide a part that pours air in the structure. A filter tank that does not sink even if it fills the filter tank with water. (Fig. 5 replaces this with a pipe), and a net and filter material are tightened thereon. Gravity from the top to the bottom is given to the filter tank by gravel or external force, and when pressed down, the upper edge of the filter tank is slightly out of the surface of the breeding aquarium so that the pumped water does not spill into the filter tank. . In this way, the outlet of the pipe that pumps up the dirty water in the breeding tank is placed under the surface of the breeding tank (same as the surface of the filtration tank) or
Lower to near the surface of the water. Then, the garbage in the breeding aquarium can be completely removed to the outside with the power of the air lift and the weak motor, that is, low energy (energy saving = economical). The same effect can be obtained as with the upper filtration, which pumps up the garbage in the breeding aquarium completely to the outside by pumping it up with a strong motor, and also has an economic effect. Conventional
The air lift was used for internal filtration, and the garbage was in the breeding aquarium, so the filtration effect was poor. The water level upper filtration of the present invention, which utilizes only the advantages of both the upper filtration and the internal filtration, can obtain the above-mentioned effect because the filtration tank is floating even when the filtration tank is pushed down. The pumping pipe penetrating the bottom of the filtration tank and the net was a double pipe in the middle, and was slid up and down to correspond to the height of the breeding aquarium. It also has the effect of being widely usable in breeding aquariums of different sizes.

(2) The suction part of the garbage in the breeding aquarium, which communicates with the pumping pipe, is widened so as to provide a living space for the shrimp and fry, and the outer hole is tapered from outside to inside. Prevented shrimp and fry entering the living space from returning to the breeding aquarium. The effect of collecting juvenile shrimp and fry will increase. (3) A hair-like or thread-like thing is installed in the suction part, and a configuration is used in which the shrimp and the like concentrate on moving things. The suction part and the pumping pipe were given backlash so that the hairs, threads, etc. could shake well. As described above, in addition to the purpose of filtration, an effective method of recovering shrimp and fry that are difficult to collect without troublesome operation was obtained. (4) As described above, since the entire filtering device is placed in the breeding aquarium, the upper surface of the breeding aquarium is neat, and the lid and the like are easily and neatly cleaned. (5) The structure is simple and can be placed anywhere in the breeding aquarium. (6) Because of the power of air, shrimp and fry are not caught in the screw and die. (7) Since the filtration tank has buoyancy and the lower structure follows the buoyancy, it does not fall down in the breeding aquarium at all. It is the same as the role of fishing during fishing. (8) When cleaning the breeding aquarium, it is the same as the lifting tool, so it is possible to easily move the filtration device out of the way of the cleaning place. (9) Since it is an air lift, aeration (dissolving oxygen into water) can be performed at the same time.
