Description

Water filtering device of water tank for aquatic organisms

Technical Field

The present invention relates to a water filter device for an aquatic organism tank, which is improved to manufacture a water filter device for aquatic organisms such as aquarium fishes, etc., which have weak swimming ability and oxygen intake ability and are sensitive to water quality deterioration, at a lower cost.

Background

Since fins, body shapes, and the like of ornamental fishes such as the tilapia and the turkey are artificially improved for a long time, they are often inferior to other fishes in swimming ability and oxygen intake ability and are extremely sensitive to deterioration of water quality, and therefore, it is necessary to frequently and carefully change water in these tanks and supply sufficient oxygen. Therefore, it is difficult to change water only by hand, and various water filters for aquarium fish capable of supplying oxygen have been proposed.

As such a water filter device for an aquarium fish tank, for example, patent document 1 discloses a submerged filter device including a filter cartridge C, a cover plate L, a filter unit U, and the like, wherein locking pieces 45 that can be engaged with and disengaged from engagement holes 13 provided on both side surfaces of the filter cartridge C are provided on both sides of the cover plate L, the locking pieces 45 are disengaged from the engagement holes 13 when elastically deformed inward of the cover plate L, and are engaged with the engagement holes 13 when elastically restored outward in the radial direction of the cover plate L, and the filter cartridge C and the cover plate L can be attached and detached by one-key operation, thereby allowing easy maintenance for replacing a filter material and the like (see claim 1 of the claim 1, paragraphs [0016] to [0024] of the specification, fig. 1, fig. 12, and the like of the accompanying drawings).

Further, patent document 2 discloses a submerged filter device for a water tank, which comprises a rotary shaft 31, a filter material main body 32 having a through passage 32a through which the rotary shaft 31 passes, and a blade member 33 through which the rotary shaft 31 passes and in which a plurality of blades (33ab, 33as) are provided around the rotary shaft 31, wherein in a filter material housing case 20 comprising a water tank submerged filter material 30 having a plurality of blade members 33 coaxially with the through passage 32a, a bottom portion 21 having a bubble discharge port 21a for discharging bubbles 2, a side wall portion 22 connected to an edge of the bottom portion 21 and having a plurality of side wall slits 22s, and a lid portion 23 having a bubble discharge port 23a for discharging bubbles 2, the rotary shaft 31 is supported by the bubble discharge port 21a and the bubble discharge port 23a, and an ascending water flow C1 caused by the bubbles 2 is housed so as to collide with the blade member 33 and rotate, oxygen is efficiently dissolved in water in the water tank, and the garbage is uniformly adsorbed, and the replacement time can be easily determined (see claim 2 of the claim of patent document 2, paragraphs [0017] to [0024] of the specification, fig. 1 and fig. 5 of the drawings).

However, although in the submerged filter devices for a water tank of patent documents 1 and 2, it is possible to filter water in the water tank and supply oxygen, in order to improve the filtering function and the oxygen supply capacity, it is necessary to increase the power of the pump, and there are problems in that: since the flow of the filtered water is also increased, the ornamental fish having weak swimming ability is easily fatigued and ill while swimming in the increased flow, and the operating sound and vibration pressure of the pump are increased, thereby causing death.

In order to solve such a problem, it is conceivable to separate a tank for keeping the aquarium fish and a tank suitable for water replacement and supply water from a replacement tank to the keeping tank. However, this requires large equipment and a certain space, which is generally difficult, and creates a new problem against the principles of cost saving, energy saving, space saving, and the like.

On the other hand, the utility model of the present application has developed a water filtration device for an aquatic organism water tank in patent document 3, which can feed water with a high degree of filtration and supply dissolved oxygen sufficiently, and can suppress the generation of water waves and bubbles by suppressing the flow of the supplied water to the limit, without hindering the "viewing from above" (viewing from the water surface), and can feed aquatic organisms such as aquarium fishes easily, at low cost, in an energy-saving and space-saving manner, without causing fatigue or stress to the fed aquatic organisms such as aquarium fishes and without impairing the original aesthetic feeling, by any person.

The water filtration device for an aquatic organism tank of patent document 3 has the above-described remarkable effects and is extremely excellent in performance, but since the manufacturing cost is slightly high, it is necessary to improve and manufacture the water filtration device at a lower cost and sell the water filtration device at a lower price in order to widen the range of customers.

The lower disc 5 has a function as a partition on which the submersible pump 4 is placed and below which a water suction space of the submersible pump 4 is provided.

[ Effect and Effect of the first Filter device ]

According to the first filter device 2 described above, when the water in the water tank is sucked by the pressure of the submersible pump 4, the sucked water flows through the plurality of layers of the wool-knitted filter materials S1 and S2. Therefore, the floating matter such as dirt like feces and fish food residue in the water is filtered while passing through the filter materials S1 and S2, and can be physically filtered. Further, according to the first filter device 2 of the present invention, bacteria and the like can be attached to the filter materials S1 and S2 to perform biological filtration, that is, decomposition of harmful substances such as ammonia dissolved in water.

Further, according to the filter device 2 of the 1 st aspect, since the submersible pump 4 is covered with the plurality of layers of the wool-knitted filter materials S1, S2, it is possible to absorb and attenuate the driving noise and vibration of the submersible pump 4, thereby improving the silencing performance. Therefore, the 1 st filter device 2 (water filter device 1) can be operated without applying pressure to fish or people.

< 2 nd Filter device >

Next, the 2 nd filter device 3 will be explained with reference to fig. 2. The 2 nd filter device 3 includes a device main body 30 which is a casing of the entire device made of the same resin as the device main body 20 and has the following functions: the water filtered by the 1 st filtering device 2 is re-filtered, and the filtered water is supplied while guiding oxygen and reducing the water flow momentum.

[ device body ]

The device main body 30 is mainly composed of a substantially cylindrical inner container 31 and the like, and a plurality of stripe-shaped convex portions 36a are formed on the outer surface thereof so as to face outward.

(inner container)

As shown in fig. 2, the inner container 31 is a bottomed cylindrical body having an inner diameter of 80mm × a height of 100mm × a thickness of 2mm, a hole for passing a connection pipe is opened in the center of the bottom surface, a flange portion 36b having a width of about 10mm is provided in the lower portion, and the base 35 is provided in the lower portion.

The stripe-shaped convex portion 36a formed on the outer surface of the inner container 31 is a stripe-shaped convex portion having a width of 5mm and a protruding height of about 5mm, and the stripe-shaped convex portion 36a is continuous in the vertical direction and provided in plurality at equal intervals in the circumferential direction of the outer surface thereof.

Here, the plurality of striped protrusions 36a can also be expected to have an effect of dry-filtering with living aerobic bacteria while volatilizing ammonia or the like.

The inner container 31 has a substantially cylindrical space in its interior for accommodating the upper plate 6 and the composite filter materials S3 and S4.

(Upper dish)

As shown in fig. 2, the upper plate 6 is provided to be raised by a convex portion by about 15mm from the bottom surface inside the inner container 31, and is constituted by a circular flat plate 60 made of the same resin as the apparatus main body 30 and having a diameter of about 75mm, and the flat plate 60 is provided with water passing portions 60a and 60b having a plurality of sizes for diffusing water discharged from the water discharge port 40a and for effectively passing water from the outside of the filter materials S3 and S4.

(composite Filter Material)

The composite filter material S3 was composed of the following components: a multilayer wool-knitted filter material S31 made of a resin; and a filter material cartridge S32 replaceably mounted at a central portion of the filter material S31. The composite filter material S4 was also composed of the following components: a multilayer wool-knitted filter material S41 made of a resin; and a filter material cartridge S42 replaceably mounted at a central portion of the filter material S41.

In this way, by using 2 filter material cartridges S32, S42, the filter material can be replaced in the inner container 31 depending on the fish to be raised and the purpose, and the filter material can be used as various filter materials that can perform physical filtration, biological filtration, chemical filtration, and the like.

(cover body)

As shown in fig. 2, the lid body 37 has an uneven portion around the periphery thereof, which is fitted into the uneven portion on the inner surface of the inner container 31, and is formed of a circular plate having an outer diameter of about 76mm × a thickness of about 2mm, and a plurality of discharge ports 37a for discharging water flowing through the inner container 31 are bored in the circular plate so as to close the upper end portion of the inner container 31.

[ Effect and Effect of the No. 2 Filter device ]

According to the 2 nd filter device 3, various kinds of filtering can be performed according to the difference of the aquarium fish, etc. raised by using the 2 filter material cartridges S32 and S42. In addition, since the 2 filter material cartridges S32 and S42 can be easily attached and detached, the filter material can be easily replaced, the inside of the apparatus can be easily cleaned, and the raising can be facilitated.

Further, according to the 2 nd filter device 3, the water flow discharged from the submersible pump 4 is discharged from the discharge port 37a after passing through the composite filter materials S3 and S4, and further, is made to flow downward from the striped convex portion 36a, and finally, collides with the flange portion 36b, and flows downward while changing the water flow in the horizontal direction, so that the generation of water waves or air bubbles is suppressed by suppressing the water flow to the limit, and the "viewing from above" is not hindered, and the ornamental fish and the like to be raised are not fatigued or stressed, are healthy without impairing the original beauty, and anyone can easily raise the fish.

Further, according to the 2 nd filter device 3, the dissolved oxygen can be sufficiently introduced into the filtered water in the process of flowing down from the striped convex portions 36 a. Therefore, an additional aeration device is not needed, the space is saved, and the cost is saved.

Further, when a part of the suction port 25a of the upper portion of the 2 nd filtering device 3 appears above the water surface, not only the overflow filtering but also the oxygen can be introduced into the water at the same time. At this time, the filter material falls from the suction port 25a and is introduced, but the sponge-like filter materials S1 and S2 are present, and therefore, the silencing performance is not impaired at all.

[ Effect and Effect of Water filtration apparatus ]

Next, the flow of water in the entire water filter device 1 will be described with reference to fig. 3. As shown in fig. 3, first, water in the water tank is sucked from the suction ports 23a and 25a of the 1 st filtration device 2. The suction ports 23a and 25a can efficiently suck water from the bottom of the water tank or the vicinity of the water surface where pollutants are likely to accumulate. Further, by setting the discharge port 37a provided in the upper portion of the apparatus main body 30 of the 2 nd filter apparatus 3 to be plural rather than single, and by changing the arrangement of the filter material and the flow of water, the inside of the apparatus main body 30 can be made into a simpler structure and configuration, and the momentum of water supplied from the discharge port 37a can be reduced, so that it can be manufactured at a lower cost and can be sold at a lower price for widening the layer of customers.

Next, the physical filtration and the biological filtration are performed by the filter materials S1 and S2, and the filter material is conveyed to the 2 nd filtration device on the water surface by the lift force of the submersible pump 4, flows through the composite filter materials S3 and S4 in the inner container 31, is discharged from the plurality of discharge ports 37a of the cover 37, flows downward after flowing through the striped convex portions 36a, collides with the flange portion 36b functioning as a rectifying plate immediately before flowing down to the water surface of the sink, and flows downward while changing the flow of water in the horizontal direction.

Therefore, when the water is supplied into the water tank, the water flow force is reduced to the limit, and therefore, pressure is not applied to ornamental fish and the like having weak swimming ability. Moreover, it suppresses the generation of water waves or air bubbles, and does not hinder the "viewing from above". Further, unlike the conventional water filtration apparatus, since the flow rate of the submersible pump 4 itself is not reduced to weaken the water flow, the filtration capacity itself is not reduced, and the filterable flow rate does not change with time, which facilitates the breeding of aquarium fishes and the like that are extremely sensitive to the deterioration of water quality.

Further, since oxygen is introduced even when the fish flows downward, it is not necessary to separately provide an aeration facility even when aquarium fish or the like having a low oxygen uptake capacity is raised.

According to the water filter device 1, in addition to the above-described action and effect, since the vibration and the driving noise of the submersible pump 4 are suppressed to be extremely small, no pressure is applied to the aquarium fish and the farmed people.

Furthermore, when the water filter device 1 is provided, the arrangement can be made extremely simple, since only the submersible pump 4 needs to be activated.

Further, since aeration is not required, wiring is only required to use 1 cord for the submersible motor, and a clean and highly flexible tank design can be performed.

Further, according to the water filter device 1, not only the composite filter materials S3 and S4 but also all the components in the device can be disassembled, assembled and disassembled, and thus the inside of the device can be easily cleaned and maintained.

Finally, the selection of the water filter device 1 will be briefly described. Although not shown, if a disk-shaped sponge filter is provided on the lid 37, the momentum of water can be further reduced. In addition, by placing the foliage plant cultivation kit to cultivate the foliage plant, the filter material can function as a water-absorbing sponge, contribute to filtration while producing a denitrification effect, and can be expected to further improve the healing effect.

[ embodiment 2]

Next, a water filtration device of an aquatic organism tank according to embodiment 2 of the present invention will be described with reference to fig. 4. Fig. 4 is a perspective view partially showing the 2 nd filter device 3 of the water filter device of the water tank for aquatic organisms according to embodiment 2. The difference from the water filter device 1 according to embodiment 1 is mainly that the water filter device has the edge wall 37b and the striped convex portions 36a are arranged, and therefore this point will be mainly described, and the same components are denoted by the same reference numerals and the description thereof will be omitted.

As shown in fig. 4, the water filter device for an aquatic organism tank according to embodiment 2 includes a rim wall 37b around the lid 37, and temporarily stores water supplied from the discharge port 37a in the water storage portion 37c, and then uniformly disperses the water in the plurality of water flow channels 37d to reduce the flow of water and flow the water downward. Therefore, the entire outer surface of the 2 nd filter device 3 can be uniformly used, and water can be made to flow downward while colliding with the convex portion 36a, and the dissolved oxygen concentration of supplied water can be increased by sufficiently dissolving oxygen in the water flow while further reducing the water flow.

Further, the water filter device for an aquatic organism tank according to embodiment 2 is formed such that a plurality of striped convex portions 36a are alternately stacked in the vertical direction. Therefore, the water flowing downward from the discharge port 37a is repeatedly divided, merged, and dropped, so that the momentum of the supplied water flow is reduced, and air is entrained in the water flow while the water flows downward while colliding with the projection, so that oxygen can be sufficiently dissolved in the water flow to increase the concentration of dissolved oxygen in the supplied water.

[ embodiment 3]

Next, a water filtration device of an aquatic organism tank according to embodiment 3 of the present invention will be described with reference to fig. 5. Fig. 5 is a perspective view partially showing the 2 nd filter device 3 according to embodiment 3. The difference from the water filtration device according to embodiment 2 is mainly that the outer surface of the 2 nd filtration device 3 is shaped like a tree stump, and therefore this point will be mainly explained, and the same components are denoted by the same reference numerals and their explanation will be omitted.

As shown in fig. 5, in the water filtration device of the aquatic organism tank according to embodiment 3, the 2 nd filtration device 3 can be used for the arrangement of the tank in a manner similar to a stump, but can be used for trees, rocks, and the like, and further, the application to glass containers, biotopes, and the like is expanded, and the effect of healing can be expected to be further improved.

[ embodiment 4]

Next, a water filtration device of an aquatic organism tank according to embodiment 4 of the present invention will be described with reference to fig. 6. Fig. 6 is a perspective view partially showing the 2 nd filter device 3 according to embodiment 4. The difference from the water filter device according to embodiment 2 is mainly that a plurality of striped protrusions 36a are arranged on the outer surface of the 2 nd filter device 3, and therefore this point will be mainly explained, and the same components are denoted by the same reference numerals and the explanation thereof will be omitted.

As shown in fig. 6, in the water filter device for an aquatic organism tank according to embodiment 4, a plurality of striped projections 36a are formed continuously in the circumferential direction of the outer surface of the 2 nd filter device and at vertically spaced intervals. Therefore, the water flowing downward from the discharge port 37a can flow downward while passing over the plurality of projections 36a, and the concentration of dissolved oxygen in the supplied water can be increased by sufficiently dissolving oxygen in the water flow while further reducing the water flow.

Although the water filtration device for an aquatic organism tank according to the embodiment of the present invention has been described in detail, the foregoing and illustrated embodiments are merely illustrative of embodiments embodied in carrying out the present invention, and are not intended to limit the technical scope of the present invention. In particular, although the case of aquarium fish such as goldfish orchid and native goldfish which are weak in swimming ability and sensitive to deterioration of water quality and change of oxygen concentration has been described, the present invention can be applied to the breeding and propagation of various other fishes, the breeding of fry and juvenile fish, the breeding of other aquatic organisms, and the like. In summary, the water filter device of the water tank for aquatic organisms according to the present invention can be widely applied to aquatic organisms having a weak swimming ability and being sensitive to deterioration of water quality and change of oxygen concentration.

Further, although it seems contradictory at first sight, if the scale is enlarged, for example, for the ornamental appearance of large fish such as koi, the difference from the conventional filter device is also remarkable in view of the silencing performance and the convenience of installation and maintenance, and it is recommended.
