Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for filtering water in an aquarium housing animals that mainly live in seawater, such as ornamental fish and shellfish and cultured fish.

[Prior Art] As a conventional method for filtering aquarium water used in fisheries in restaurants and the like, the method shown in FIG. 4 is known. In this method, the water in the water tank 51 flows down from the opening of the diverging type vibrator 52 penetrated into the water tank 51, and first, the water in the water tank 51 flows down from the opening of the diverging type vibrator 52, which is penetrated into the water tank 51, and first, the water flows down from the opening of the vibrator 52, which is made of a wool mat or the like. After being filtered by the filter material 53, the biological filter material 5 made of coral sand etc.
4 and a filter 55 and stored in a lower water tank 56. This stored water is stored in the lower water tank 56
Water is sucked in through a suction port 57 located inside the water tank, and water is sprayed from a sprinkler pipe 60 via a water pipe 59 by a water pump 58 connected to the suction port 57, and is returned to the water tank 51 and circulated.

[Problems to be Solved by the Invention] However, in this aquarium water filtration method, since the coral sand 54 that performs biological filtration is always present in the water, it is difficult for aerobic bacteria to grow.
It has been difficult to maintain conditions suitable for fish and shellfish habitat. In addition, in the conventional method, in order to perform biological filtration more efficiently, a large amount of coral sand 54 is required, and a large-scale lower water tank 56 and piping must be designed and installed. The drawback was that a special place had to be set up for it. In addition, in the conventional method, the water in the aquarium 51 is not circulated efficiently, so when actually breeding fish etc., the aquarium 51
It also has the disadvantage that fish and shellfish excreta, leftover bait, etc. accumulate at the bottom.

Therefore, the present invention promotes the growth of aerobic and halophilic bacteria to ensure smooth biological filtration.
An object of the present invention is to provide a highly practical aquarium water filtration method in which the aquarium water circulates.

[Means for solving the problem] Water in an aquarium is pumped up, this pumped water is filtered and stored using a physical filter medium and a biological filter medium, and the stored filtered water is instantaneously and intermittently pumped into the aquarium. The solution was to allow the water to flow inside.

In addition, the water in the aquarium is allowed to flow down, this flowing water is filtered with a physical filter medium and a biological filter medium, and this filtered water is pumped,
The solution was to temporarily store this pumped water and then instantaneously and intermittently blow out the stored water upward from the bottom filter at the bottom of the tank.

＼ [Function] When water in an aquarium is momentarily and intermittently circulated through a separate biological filtration material, it comes into contact with the biological filtration material or with air and water alternately. , and the reproduction of aerobic bacteria becomes active. As a result, biological filtration is carried out smoothly, and conditions similar to those on a rocky shore or at the edge of the ocean can be recreated, making it possible to maintain conditions suitable for marine fish to live in.

[Example 1] Figures 1 and 2 show a first example of the aquarium water filtration method of the present invention, and reference numeral 1 in the figures indicates an aquarium. Inside this water tank l, there is a suction port 2, which is connected to the suction end of a water pump 3. A water sprinkling pipe 4 is connected to the discharge end of the water pump 3, and the water sprinkling pipe 4 is arranged so as to be located at the upper part of the water tank l. Further, a storage tank 5 is installed below the water sprinkler pipe 4 so as to be located above the water tank 1 . The central part of this storage tank 5 is
It is partitioned by a filter 6 having a parallel surface to the side surface, and the storage tank is divided into two by this filter 6.

A biological filtration material 7, an upper filter 8, and a physical filtration material 9 are sequentially stacked on one side of the divided storage tank 5.
The receiver is located so as to receive water sprinkled from the sprinkler pipe 4. Further, a pipe 10 for feeding water to the water tank 1 is installed at the bottom of the other divided storage tank. Furthermore, a valve mechanism 11 is installed inside the storage tank 5 at a connection portion between the pipe IO and the storage tank 5 .

In addition, an overflow vibe 12 is provided on the side of the storage tank 5.
is located adjacent to it.

Here, a detailed view of the valve mechanism 11, which is the key point of this device, is shown in FIG. Reference numerals 5, IO1, and II in the figure represent a storage tank, a pipe, and a valve mechanism, respectively, as in FIG. 1. This valve Jihl + 1 roughly consists of a float valve I3 and a float chamber 14 that accommodates this float valve 13. It is a water chamber 15. Also, in the ice receiving chamber 15 on the upper surface of the float chamber 14, a Xyphon 16 and an air vent pipe 1
7 is provided on the outer bottom surface of the float chamber 14,
A reverse stop valve 18 is formed for draining water in the float chamber 14. Further, the shape of the float valve 13 may be either cylindrical or square prism as long as it has a valve function.
The bottom surface j of the a meet 1 is a disc-shaped valve body 20 that closes the IJIJ 0 part of the pipe 10 via the central axis 19.
are integrally formed.

As shown in FIG. It is installed on the inner surface of the storage tank 5 in such a position that the storage tank 5 is closed.

In an aquarium water filtration device having such a valve machine, water in the aquarium 1 is first sucked in through the suction port 2 and sent to the water sprinkler pipe 4 by the water pump 3. After being filtered by a physical filter material 9 made of wool mat or the like, it is passed through an upper filter 8 and filtered by a biological filter material 7 made of coral sand or the like. stored in. Here, after the filtered water that has permeated from the filter 6 accumulates in the empty storage tank 5 as shown in FIG. 2 to a height equivalent to the upper wall surface 21 of the float chamber 14,
The water flows over the upper part of the wall 21 into the water receiving chamber 15, the water level in the water receiving chamber I5 becomes high, and the filtered water is turned on! 6 into the float chamber 14. Then, valve body 2
The float valve 13 integrated with 0 floats up, 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. Further, the water accumulated in the float chamber 14 is released from the check valve I8.

As above, create an aquarium! The water in the water is physically and biologically filtered, instantaneously and intermittently.
It is reduced to 1 and circulates without stagnation.

In order for these biological filtration to circulate smoothly, it is necessary that the size of the filter, the side of the biological filtration sand, and the size of the biological filtration sand grains are matched, and that oxygen-containing water is constantly circulated. It is necessary to do so. By the way, in this example, since the structure is such that the biological filter material 7 and the valve mechanism 11 are suspended in the storage tank 5 through the filter, the storage tank 5
Since the water stored in the filter flows down intermittently and instantaneously to the valve machine, the biological filter sand 7 is brought into contact with air and water alternately, and aerobic bacteria are Reproduction takes place actively on the surface of the biological filter medium 7.

The biological filter sand grains used as the biological filter medium 7 preferably have a diameter of about 1 mm to 2 mm.

Furthermore, the frequency with which the stored water flows down depends on the capacity of the water pump 3, and preferably, it is appropriate to flow down the water every 2.3 minutes.

In addition, the valve machine (1) is not limited to the Zyfon type shown in Fig. 2, but for example, the 711 [1] is a combination of a valve and a timer that opens and closes intermittently, and the water level in the float chamber. It is also possible to use a valve that opens and closes depending on the position change caused by the rise.

In addition, it is also possible to provide a bottom filter at the bottom of the water tank l and connect a pipe IO to this to provide a blow-up type filtration method.

In addition to the physical filter material 9, some biological treatments are also performed at the same time.

Next, FIG. 3 shows a second example of the aquarium water filtration method of the present invention. The water in the aquarium 22 flows down from the opening of the diverging type vibrator 23 penetrated into the aquarium 22, and is first filtered by a physical filter material 24 made of wool mat or the like, and then filtered by a biological filter material 24 made of coral sand or the like. The water is further filtered by the filter material 25 and the filter 26 and stored in the lower water tank 27 .

This stored water is sucked in through a suction port 28 installed in the lower water tank 27, and a pump 29 connected to the suction port 28
The water is pumped up and guided to the water sprinkling pipe 3I via the water pipe 30, where it is sprinkled into the storage tank 32. The water stored here is automatically transferred to a pipe 34 connected to a valve t133 by a valve mechanism 33 built into the bottom of the storage tank 32.
Water is supplied instantaneously and intermittently. This pipe 34 is connected to a bottom filter 35 located at the bottom of the water tank 22, and the supplied water is instantaneously and intermittently discharged from the bottom filter 35 and the outlet 36 connected thereto. . This air outlet 36 is opened in the horizontal direction, and the force of the water blown out causes the aquarium 22 to
The idea is to stir the water inside horizontally. Also,
The upper side of the bottom filter 35 and the exposed bottom of the aquarium 22 are covered with biological filter sand 37, which is not only a mechanical filter medium but also has the function of attaching filtration bacteria. contributes to the reproduction of

The valve mechanism 33 used in this example is similar to the valve mechanism II of the first example shown above, and these valve mechanisms 33.1
1 has a float valve 13, so the valve opens and closes intermittently depending on the water level in the tank, and operates automatically. Further, in this example, since the water pump 29 is installed in the lower water tank 27 whose water level fluctuates due to the action of the valve mechanism 33, the water level in the lower water tank 27 is adjusted to the suction port 28 connected to the water pump 29. Do not fall below the position of
It is necessary to adjust the height position of the suction port 28.

For example, a vibrator 34 with an inner diameter of 56 mm is piped to the bottom of a storage tank 32 with a capacity of 17 liters, the length of the central axis 19 is 40 mm, and the height is 50 mm.
An experiment was conducted using a valve mechanism 33 having a float valve 13 made of a rectangular prism of nu++X I 30+++m.
The water in the storage tank 32 flowed down inside the vibrator 34 at a flow rate of 3.5 liters/second, and was circulated with good reproducibility. In addition, aquarium 2
2, the biological filter sand 37 spread on the bottom part is about 5
It is appropriate to cover the bottom filter 35 with a thickness of 0 mm or less so as not to impair the function of the filter and to prevent the growth of bacteria.

In this example, biological treatment is performed on the physical filter medium 24 and the biological filter sand 37 at the same time.

[Effects of the Invention] The aquarium water filtration method according to the present invention pumps water in an aquarium, filters and stores the pumped water using a physical filter medium and a biological filter medium, and instantly converts the stored filtered water into It is characterized by flowing down into the aquarium intermittently and intermittently, and the water in the aquarium is allowed to flow down and this flowing water is filtered with a physical filter material, [j] and biological filter sand. The filtered water is pumped up, the pumped water is temporarily stored, and the stored water is momentarily and intermittently blown out from the bottom filter at the bottom of the tank toward the top of the tank. As a result, the biological filtration medium comes into contact with air and water alternately, and aerobic bacteria actively reproduce on the surface of the biological filtration medium, and the water in the aquarium becomes stagnant. Since the water circulates without any disturbance and biological filtration takes place, conditions similar to those found on a rocky shore or at the edge of the ocean can be recreated, making it possible to maintain conditions suitable for marine fish to live in.

In addition, compared to conventional methods, the filtration method of the present invention allows the biological filtration function to circulate even if the number of claws of the biological filter material is small, making it possible to make aquariums other than breeding aquariums more compact. There is no need to set up a special place. In addition, when using a water pump or a small pump, it has a built-in valve mechanism, so that when the valve is intermittently idle, the water in the aquarium is instantaneously, intermittently, and automatically. It can be circulated, and as a result, the water does not spoil and the trouble of washing the aquarium can be saved.
