[0010] In these figures, reference numeral 12B denotes an ornamental fish tank filtering device, and a filter tank casing 13B mounted on the ornamental fish tank 1 and a lid 13C covering the open upper surface of the filter tank casing 13B. A pump mechanism 20 partially accommodated in the filtration tank casing 13B, a first filtration mechanism 30 accommodated in the filtration tank casing 13B, and an ornamental fish tank 1 arranged in the first filtration mechanism 30. And a second filtering mechanism 40 connected thereto. In order to support the second filtration casing 41 constituting the second filtration mechanism 40 on the lower surface on the rear side of the filtration tank casing 13B, the locking piece 14 bent down and bent forward in an L-shape after hanging is provided. Is provided.

The pump mechanism 20 includes a motor 21 housed in the filtration tank casing 13B, a first cylindrical member 22 extending downward from the motor 21 to the inside of the ornamental fish tank 1, and a first An inner frame 23 provided at the lower end of the cylindrical member 22 and containing the rotating blades, a second cylindrical member 24 extending downward from the intermediate frame 23, and a lower end of the second cylindrical member 24. It comprises a strainer 25 attached and a pumping pipe 26 extending from the middle frame 23 to the inside of the filtration tank casing 13B, and having a U-shaped tip.

The first filtration mechanism 30 includes a first filtration casing 31 in which a water reservoir 31p for retaining water from the pumping pipe 26 is formed by a partition wall 31w, and a first filtration casing 31 mounted on a bottom of the first filtration casing 31. A first filtering member 33 for performing physical filtration accommodated in a space formed by the bottom plate 32 placed, the vertical portion 32h of the bottom plate 32, and the partition wall 31w; An end is constituted by a gutter 34 supported by support pins 32p of the bottom plate 32.

Drain holes 31 ha and 31 hb are formed at the bottom of the first filtration casing 31, a plurality of narrow slits 32 s are formed at the bottom of the bottom plate 32, and the bottom plate 32 is formed at the bottom of the first filtration casing 31. By mounting, a flow path is formed between both bottoms. The gutter 34 is supported in a state where the partition wall 31w side is high and the support pin 32p side is low. Water flows from the partition wall 31w side to the support pin 32p side, and the projection 34i located on the upstream side and the downstream side of the projection 34i are adjacent to the projection 34i. A large number of pairs of holes 34h having the same width as the width of the projections 34i are provided on the plane portion, and water from the water reservoir 31p is supplied to the first filter 33 from the holes 34h.

Reference numerals 35A and 35B denote floats arranged corresponding to the drain holes 31ha and 31hb, and reference numeral 36 denotes a drain pipe connected to the drain hole 31ha. Water is returned from the drain pipe 36 to the ornamental fish tank 1. The above-mentioned second filtration mechanism 40 is provided with a box-shaped second filtration casing 41 which can be opened and closed, and is accommodated in the second filtration casing 41 so as not to mix a plurality of second filtration materials. And a plurality of buckets 42 to be accommodated.

The second filter casing 41 is detachably supported on the first filter casing 31 by locking the L-shaped locked piece 41f provided at the upper end to the locking piece 14, The inflow port provided on the upper surface is connected to the drain hole 31hb by the connection pipe 43. Further, the water from the drain hole 31hb is filtered by the second filter medium that performs biological filtration accommodated in the bucket 42 while rising and then descending to the lower end, and then is viewed from the drain hole 41h provided on the upper front surface. It is returned to the fish tank 1.

Next, the filtration will be described. First, the water in the ornamental fish tank 1 sucked from the strainer 25 by the rotation of the motor 21 is supplied to the water reservoir 31p via the second cylindrical member 24, the middle frame 23, and the pumping pipe 26. When the water overflows from the water reservoir 31p, the water flows through the gutter 34, and the large dust caught on the projection 34i is removed by the projection 34i. The water is supplied from 34h to the first filter medium 33 so as to spray water.

[0017] When water is supplied in this manner, oxygen can be dissolved by the showering effect, and thus the dissolved rate of oxygen increases. Then, the water that has been physically filtered by the first filter medium 33 accumulates in the first filtering casing 31, and 70% to 80% of the water is returned to the ornamental fish tank 1 from the drain hole 31ha, and the water is drained. From the hole 31hb, 20% to 30% is supplied to the second filtration casing 41.

The water supplied to the second filtration casing 41 as described above is subjected to biological filtration by the second filtering material in the bucket 42 and then returned to the ornamental fish tank 1 from the drain hole 41h. . The reason why the water of 20% to 30% is supplied to the second filtration casing 41 is to reduce the volume of the second filtration casing 41 to make the biological filtration slow and effective, and to reduce the volume of the ornamental fish. This is to increase the breeding area in the aquarium 1.

As described above, according to one embodiment of the present invention, dust is removed from the water before being supplied to the first filter medium 33 by the projections 34 i of the gutters 34. 3 can be delayed, and the replacement or cleaning interval of the first filter medium 33 can be lengthened. Since the floats 35A and 35B are arranged so as to cover the drain holes 31ha and 31hb, the bubbling sound when water falls through the drain holes 31ha and 31hb can be eliminated, and the floats 35A and 35B can reduce the showering effect. Since it is not generated, that is, since the floats 35A and 35B are covered so as not to entrap the air, the dissolved carbon dioxide is not dispersed.

Further, since the biological filtration is performed by the second filtration mechanism 40 after the physical filtration is performed by the first filtration mechanism 30, the first filtration material 33 of the first filtration mechanism 30 is clogged. When the first filter medium 33 is removed for replacement, the second filter mechanism 40 functions, so that biological filtration can be performed by the second filter mechanism 40 and the water quality can be improved. Condition can be maintained. And since the 2nd filtration mechanism 40 is arrange | positioned in the ornamental fish tank 1, even if water leaks from the 2nd filtration mechanism 40, it will not wet the surroundings.

Further, since the first filtering mechanism 30 is placed on the ornamental fish tank 1 and the second filtering mechanism 40 is arranged in the ornamental fish tank 1, the second filtering mechanism 40 is Since the first filter medium 33 can be removed from the first filtration mechanism 30 without removing the first filter medium 33 from the ornamental fish tank 1, when the first filter medium 33 is to be replaced or cleaned only, the second filter mechanism 40 is used. It is not necessary to spread the garbage such as sludge into the ornamental fish tank 1.

FIG. 6 is an explanatory view showing a configuration of an ornamental fish apparatus to which an ornamental fish tank filtering apparatus according to another embodiment of the present invention is applied, and is a view corresponding to FIG. Note that, in this embodiment, the second filtration casings 41 and 41A of the second filtration mechanism 40 are connected by a connection pipe 44 so that water flows from the second filtration casing 41 to the second filtration casing 41A. Therefore, the effect of biological filtration becomes significant.

In the above-described embodiment, the example in which the projection 34i and the hole 34h provided on the gutter 34 are paired has been described. However, the projection 34i and the hole 34h are relatively provided such that the projection 34i is on the upstream side and the hole 34h is on the downstream side. Thus, a similar effect can be obtained. In addition, although an example has been described in which water is refluxed from the first filtration mechanism 30 to the ornamental fish tank 1, even if all the water is supplied from the first filtration mechanism to the second filtration mechanism, the second filtration is sufficiently performed. If biological filtration can be performed by the mechanism, a configuration may be adopted in which all water is supplied from the first filtration mechanism to the second filtration mechanism.

[0024]

[Effect of the invention]

 As described above, according to the present invention, the filtration mechanism includes a first filtration mechanism for performing physical filtration, and a second filtration mechanism for performing biological filtration on water from the first filtration mechanism. And the second filtration mechanism is placed in the ornamental fish tank, so even if it is removed to replace the filter medium of the first filtration mechanism, biological filtration can be performed by the second filtration mechanism. Thus, the water quality can be maintained in a good state, and the surroundings do not get wet even if water leaks from the second filtration mechanism.

Further, since the first filtration mechanism is placed on the ornamental fish tank and the second filtration mechanism is arranged in the ornamental fish tank, the second filtration mechanism is not taken out of the ornamental fish tank. Since the filter medium can be taken out from the first filter mechanism, when replacing or cleaning only the filter medium of the first filter mechanism, dirt such as sludge in the second filter mechanism is diffused into the ornamental fish tank. You don't have to.
