1 and 2 show a first example of a method for filtering aquarium water according to the present invention, in which reference numeral 1 is a water tank. In the water tank 1, there is a suction port 2, which is connected to the suction end of a pump 3. A sprinkling pipe 4 is connected to the discharge end of the pumping pump 3, and the sprinkling pipe 4
Are arranged so as to be located above the water tank 1. A storage tank 5 is arranged below the sprinkling pipe 4 so as to be located above the water tank 1. The central portion of the storage tank 5 is partitioned by a filter 6 that is parallel to the side surface of the storage tank 5, and the storage tank 5 is divided into two parts by the filter 6. A biological filter 7, an upper filter 8, and a physical filter 9 are sequentially stacked on one of the divided storage tanks 5 and are positioned so as to receive water spray from the water spray pipe 4. A pipe 10 for sending water to the water tank 1 is provided at the bottom of the other of the divided storage tanks. Further, a valve mechanism 11 is installed inside the storage tank 5 at a connecting portion between the pipe 10 and the storage tank 5, which are piped.
In addition, the overflow pipe 12 is provided on the side surface of the storage tank 5.
Are provided adjacent to each other.

The valve mechanism 11 is shown in detail in FIG. Reference numeral 5, reference numeral 10 and reference numeral 11 in the figure denote a storage tank, a pipe and a valve mechanism, respectively, as in FIG. The valve mechanism 11 is roughly composed of a float valve 13 and a float chamber 14 accommodating the float valve 13, and an upper portion of a wall surface of the float chamber 14 is formed higher than an upper surface of the float chamber 14 to receive the water. It is 15. Further, a siphon 16 and an air vent pipe 17 are provided in the water receiving chamber 15 on the upper surface of the float chamber 14.
A check valve 18 for draining water in the float chamber 14 is formed on the outer bottom surface of the. Further, the shape of the float valve 13 may be a cylindrical shape or a square pillar shape as long as it has a valve function, and the bottom surface of the float valve 13 is a disc that opens and closes the opening of the pipe 10 via the central axis 19. The valve body 20 is integrally formed. As shown in FIG. 2, the valve mechanism 11 formed as described above has a disc-shaped valve body 2 in a state in which the float valve 13 is in contact with the bottom surface of the float chamber 14.
It is mounted on the inner surface of the storage tank 5 so that the position 0 closes the opening of the pipe 10. Further, if the flow rate of water is large, a hole (not shown) may be provided in the float chamber 14 instead of the siphon 16. Further, instead of forming the check valve 18 in the float chamber 14, a tube (not shown) for supplying water to the water tank 1 or the storage tank 5 may be provided.

In the aquarium water filtering apparatus having the valve mechanism 11 as described above, the water in the aquarium 1 is first sucked through the suction port 2 and sent to the sprinkler pipe 4 by the pump 3, and the wool After being filtered by a physical filter medium 9 made of mat or the like, it is filtered by a biological filter medium 7 made of coral sand or the like through an upper filter 8 and from the filter 6 to a storage tank 5 having a valve mechanism 11. Be stored. Here, the storage tank 5 in an empty state as shown in FIG.
The filtered water that has permeated from the filter 6 flows into the float chamber 14
After having accumulated to the same height as the upper wall portion 21 of the water, it flows over the upper wall portion 21 and flows into the water receiving chamber 15,
And the filtered water enters the float chamber 14 via the siphon 16. Then, the float valve 13 integrated with the valve body 20 floats, the opening of the pipe 10 is opened, and the water stored in the storage tank 5 automatically and instantaneously flows into the pipe 10. Has become. In addition, the water accumulated in the float chamber 14 is stored in the check valve 18
Is released more. As described above, the aquarium 1
The water therein is physically and biologically filtered, instantaneously and intermittently returned to the water tank 1, and circulates without stagnation.

In order to smoothly circulate these biological filters, the size of the filter, the amount of the biological filter sand, and the size of the biological filter sand particles are commensurate with each other, and the oxygen-containing water is always used. It needs to be in circulation. By the way, in this example, since the biological filter material 7 and the valve mechanism 11 are provided in the storage tank 5 through the filter 6, the stored water in the storage tank 5 is intermittently and instantaneously transferred by the valve mechanism 11. The biological filter material 7 is alternately brought into contact with air and water so that aerobic bacteria are propagated uniformly and actively on the surface of the biological filter material 7.

Further, the valve mechanism is not limited to the siphon type shown in FIG. 2, but is, for example, one in which an electromagnetic valve and a timer are combined to open and close intermittently,
It is also possible to use a device in which the valve is opened and closed depending on the position change of the float chamber due to the rise of the water level. In addition, a bottom filter may be provided on the bottom of the water tank 1, and the pipe 10 may be connected to the bottom filter to provide a blow-up type filtration method. In addition, also in the physical filter medium 9, a part of biological treatment is simultaneously performed.

In the first example of the method for filtering aquarium water, the water in the aquarium 1 is pumped up, and the pumped water is filtered by the physical filter medium 9 and the biological filter medium 7 and stored. By flowing the stored filtered water instantaneously and intermittently so that the biological filter 7 comes into contact with air and water alternately, aerobic bacteria are removed from the biological filter 7. It actively reproduces evenly and evenly on the surface, and because the water in the aquarium 1 circulates without stagnation and biological filtration is performed very efficiently, the state similar to that at the beach and the beach is reproduced, and saltwater fish etc. Can be kept in a suitable condition to live in. Further, compared to the conventionally used method, in the filtration method according to the present invention, the amount of biological filtration material may be small, aquariums other than the aquarium for breeding can be made compact, and a special place can be provided. No need to provide. In addition, even if a small pump is used, since the valve mechanism is built in, the aquarium water can circulate instantaneously, intermittently, and automatically with the intermittent opening and closing of the valve. As a result, the water does not spoil, and the labor of washing the aquarium can be saved.

Next, FIG. 3 shows a second example of the method for filtering aquarium water according to the present invention. The water in the water tank 22 flows down from the opening of the divergent pipe 23 penetrating into the water tank 22, and is first filtered by a physical filter material 24 made of wool mat or the like, and then biological water made of coral sand or the like. Filter material 2
5 and the filter 26, and further stored in the lower water tank 27. The aquarium water is sucked from a suction port 28 installed in the lower water tank 27, pumped by a pump 29 connected thereto, guided to a sprinkler pipe 31 via a water supply pipe 30, and stored in a reservoir 32. Is sprinkled on. The water stored here is instantaneously and intermittently sent to the pipe 34 connected to the valve mechanism 33 by the automatic operation of the valve mechanism 33 built in the bottom surface of the storage tank 32. The pipe 34 is piped to a bottom filter 35 located at the bottom of the water tank 22, and the water sent is instantaneously and intermittently discharged from the bottom filter 35 and a blowout port 36 connected thereto. . This outlet 36
It is opened in the horizontal direction, and the force of the blown out water is intended to laterally stir the water in the water tank 22. In addition, the upper side of the bottom filter 35 and the water tank 22.
Biological filter sand 37 is spread on the exposed bottom surface of this, and this is not only a mechanical filter, but also has a function to attach filter bacteria, which contributes to the growth of bacteria. .

The valve mechanism 33 used in this example is similar to the valve mechanism 11 of the first example shown above. Since these valve mechanisms 33, 11 have the float valve 13, The valve opens and closes intermittently depending on the water level in the tank and operates automatically. Further, in this example, since the pumping pump 29 is installed in the lower water tank 27 in which the water level fluctuates due to the function of the valve mechanism 33, the water level in the lower water tank 27 is the suction port 28 connected to the pump 28. It is necessary to adjust the height position of the suction port 28 so that it does not fall below the position.

For example, a pipe 34 having an inner diameter of 56 mm is provided on the bottom surface of a storage tank 32 having a capacity of 17 liters, the center shaft 19 has a length of 40 mm, and a height of 50 mm.
Experiments were carried out using a valve mechanism 33 having a float valve 13 consisting of a 130 mm × 130 mm square column. As a result, the water in the storage tank 32 has a flow rate of 3.5 liters in the pipe 34.
It flowed down in seconds and circulated with good reproducibility. In addition, the biological filter sand 37 spread on the bottom of the water tank 22 is about 50 m.
Spreading on the bottom filter 35 with a thickness within m is
It does not impair the function of the filter and is also suitable for bacterial growth.

In the second example of the method for filtering aquarium water, the water in the aquarium 22 is caused to flow down, and the flowing water is filtered by the physical filter material 24 and the biological filter material 25. The filtered water is pumped up, the pumped water is temporarily stored, and the stored water is instantaneously and intermittently blown out from the bottom filter 35 at the bottom of the water tank 22 toward the upper side of the water tank 22,
By allowing the biological filter material 25 to come into contact with air and water alternately, the same action and effect as the method for filtering aquarium water in the first example can be obtained.
