Description

[Detailed Description of the Invention] The present invention relates to a filtration device for a live fish tank that maintains the water flow, water quality, and water temperature necessary for breeding live fish.

Previously, aquariums for raising live fish were simple, such as controlling the temperature of the seawater supplied, so the water quality deteriorated in a short period of time, making it impossible to raise live fish for a long period of time. This method had drawbacks such as requiring frequent replacement of seawater.

In view of these drawbacks, the present invention arranges a stagnation tank that communicates with the live fish tank through the bottom, a water temperature control device in the stagnation tank, and a dam plate adjacent to the stagnation tank. A filtration tank is arranged which communicates with the stagnation tank in the upper water area through the filtration tank, and sand,
Filled with granular filter media such as crushed stones, bacteria that decompose live fish excrement, etc. are retained in the filter media, and the path between the bottom of the filter tank and the aquarium absorbs the water in the filter tank and is absorbed into the aquarium. A pump device is installed to re-supply water to the filtration tank, and a discharge pipe is introduced into the upper part of the filtration tank, and a reverse pipe is installed between the bottom of the filtration tank and the stagnation tank, which absorbs water in the stagnation tank and squirts it out to the bottom of the filtration tank. A filtration device for a live fish tank equipped with a stopper water suction pipe is provided to solve the above-mentioned drawbacks, and one embodiment of the present invention will be described below based on the drawings. 1 is a breeding device for live fish. A large water tank 3 is provided on one side of the box-shaped main body 2, and a water quality control section 4 and a machine room 5 are respectively arranged adjacent to the water tank 3, and above the water tank 3 there is a separate A small water tank 6 is placed thereon.

The water quality control unit 4 consists of a stagnation tank 7 and a filtration tank 8.
The stagnation tank 7 is communicated with the water tank 3 between the bottom parts through a return pipe 10 installed in communication between the lower part of the partition wall 9 between the water tank 3 and the water tank 3, and is configured to be maintained at the same water level as the water tank 3, Also, within the stagnation tank 7 is a water temperature control device 14 comprising a heater 11 and a cooling coil 13 controlled by a cooling compressor 12.
The water temperature control device 14 is controlled by a temperature sensor 16 connected to a thermostat 15 to maintain the water temperature at a predetermined temperature.

In addition, the filtration tank 8 is placed in communication with the stagnation tank 7 in the upper water area via a dam plate 17 that is interposed below the standard water level A of the stagnation tank 7, and the inside of the filtration tank 8 is free from sequestration. A filter medium 18 made of granular materials such as crushed stone and sand is filled, and bacteria 19 for biochemically decomposing live fish excrement etc. are retained in the upper region of the filter medium 18.

Incidentally, reference numerals 20 and 20a are water supply holes penetrated through the dam plate 17 for use when the water level is low.

Reference numeral 21 denotes an overflow mechanism section installed in the small water tank 6, and its upper end is positioned corresponding to the reference water level B of the water tank 6 at a drain port 22 which is formed at the bottom of the water tank 6 and opens into the large water tank 3. The lower ends of the water pipes 23 are connected to each other, and the water pipes 23 are connected to each other.
A shielding tube 25 is disposed on the outer periphery of the water channel 24 with water channels 24 at appropriate intervals, and the upper end of the shielding tube 25 is made to protrude above the reference water level B to divide the water channel 24. A communication hole 26 is provided at the bottom of the water tank 25 to communicate the bottom of the water tank 6 with the inside of the water channel 24.
is formed.

27 is a water supply mechanism section, and at the bottom of the filtration tank 8 there is disposed a water absorption member 28 which is treated to prevent the filter medium 18 from being sucked in by wrapping a fine net or the like around a porous pipe body; The water intake port 3 of the pump device 29 in which the water absorption member 28 is installed in the machine room 5
0 through a suction pipe 31, and one end of a water spout 33 is connected to the water spout 32 of the pump device 29, and the other end of the water spout 33 is branched into two systems to connect the water tank 3, The water introduced into the upper surface of the end of the tank 6 and circulated and sucked by the pump device 29 through the nozzles 34 and 34a at the tip is pumped into the water tank 3 and 6.
It is designed to generate a water flow inside and discharge water from the side.

In addition, 35, 35a... are water suction pipe 31, water discharge pipe 33
This is a valve inserted in the path of

Also, the water outlet 32 of the pump device 29 and the water suction member 28
A bypass pipe 37 for a reverse valve with a valve 36 interposed therebetween is interposed therebetween, and a water intake pipe 38 for a reverse valve whose one end is introduced into the bottom of the stagnation tank 7 is connected to the water inlet 30 via a valve 39. In addition, one end of a drain pipe 40 is introduced into the upper part of the filtration tank 8 via a valve 41, and these bypass pipes 3 for reverse plugs are connected to each other.
7. Reverse valve water suction pipe 38 and drain pipe 40 are used to perform water exchange and cleaning of the filter tank 8.

Next, to explain the operation of the filtration device for a live fish tank according to the present invention, in a normal state, the aquarium 3,
The stagnation tank 7 and the filtration tank 8 are held at a reference water level A, and the water tank 6 is similarly held at a reference water level B, and the water sucked from the water suction member 28 is discharged by the operation of the pump device 29 of the water supply mechanism section 27. Water is discharged from the nozzles 34, 34a at the tips of the water pipes 33 into the respective water tanks 3, 6, creating a natural flowing state in the water tanks 3, 6.

In the water tank 6, excess water due to water discharge flows into the upper end opening of the water pipe 23 of the overflow mechanism section 21, and falls into the water tank 3 below through the drain port 22 connected to the water pipe 23. At that time, the water flowing into the water pipe 23 is transferred to the water tank 6.
Since the water that has flowed into the water channel 24 in the shielding cylinder 25 from the bottom side through the communication hole 26 is drained sequentially, circulating water is supplied from the old water layer on the bottom side, which is preferable for maintaining the concentration in the water tank 6. It is made like this.

Also, the water stored in the water tank 3 is stored in the water absorbing member 28 in the filter tank 8.
Along with the water absorption from
The water flows from the stagnation tank 7 through the upper water area of the dam plate 17 into the adjacent filtration tank 8, and is heated by the water temperature control device 14 while passing through the flow path from the bottom to the top in the stagnation tank 7. Alternatively, when the water is cooled and the water temperature is controlled to a set temperature, and the water that flows into the filtration tank 8 passes between the particles of the filter medium 18 filled in the filtration tank 8 on the way to the water absorption member 28 at the bottom, At the same time, excrement and other impurities are removed, and bacteria 1 remaining in the filter medium 18 are removed.
9, the excrement is biochemically decomposed, and only water purified by this action is absorbed from the water absorption member 28 at the bottom and re-supplied into each water tank 3, 6 by the pump device 29, and this series of cycles As a result, the water in the water tanks 3 and 6 is forcibly circulated and filtered.

Also, when it is necessary to clean the filter medium 18 etc. after long-term use, the valves 35, 35 of the water suction pipe 31 and the water discharge pipe 33 are used.
... is closed to cut off the normal water absorption circulation path from the water absorption member 28 to the water discharge pipe 33, and
The valves 36 and 39 of the reverse valve bypass pipe 37 and the reverse valve water suction pipe 38 are closed to form a water suction path from the reverse valve water suction pipe 38 to the water absorption member 28 via the pump device 29, and further the filtration tank 8 The valve 41 of the drain pipe 40 connected to the filtration tank 8 is opened and drained sequentially from the upper side of the filter tank 8 through the drain pipe 40. From this state, the pump device 2 is opened.
9 is activated, the water in the stagnation tank 7 and the water tank 6 connected thereto is absorbed from the bottom of the stagnation tank 7 through the reverse valve water suction pipe 38, and the water in the upper part of the water absorption member 28 is absorbed through the reverse valve bypass pipe 37. Filter medium 1
It is ejected in eight directions, and due to this ejection action, the filter medium 1
Impurities, sludge, etc. that have adhered and accumulated on the filter medium 8 float to the surface and are drained outside from the upper drain pipe 40, thereby cleaning the filter medium 18.

In short, the present invention arranges a stagnation tank 7 that communicates with the aquarium 3 for live fish through the bottom, and a water temperature control device 14 is arranged in the stagnation tank 7. The water that is circulated and re-supplied can be maintained at a predetermined set temperature in advance, and a filtration tank 8 is provided adjacent to the stagnation tank 7, which communicates with the stagnation tank 7 in the upper water area via a dam plate 17. place,
The filter tank 8 is filled with a granular filter medium 18 such as sand or crushed stone, and bacteria 19 that decompose the excrement of live fish are retained in the filter medium 18, so that the water flowing into the stagnation tank 7 is sequentially filtered. While passing from the upper part to the lower part, the excrement and impurities of the live fish can be adsorbed and separated by the filter medium 18, and the excrement is biochemically decomposed by the bacteria 19 to efficiently purify the circulating water. Also, in the path between the bottom of the filtration tank 8 and the water tanks 3 and 6, there is a pump device 29 that absorbs water in the filtration tank 8 and re-supplies it into the water tanks 3 and 6.
, it is possible to construct a forced circulation path for the stored water that flows from the water tanks 3 and 6 to the filter tank 8 and is supplied to the water tanks 3 and 6 again. A drainage pipe 40 is introduced into the upper part of the filtration tank 8, and a stagnation tank 7 is installed between the bottom of the filtration tank 8 and the stagnation tank 7.
Since a reverse stop water suction pipe 38 is installed that absorbs the water inside and spouts it to the bottom of the filtration tank 8, when it is necessary to clean the filter medium 18 etc. due to long-term use, the water is spouted upward from the water absorption member 28 toward the filter medium 18. Due to this ejecting action, impurities, sludge, etc. that have adhered and accumulated on the filter medium 18 float to the surface and are drained to the outside from the upper drain pipe 40, allowing the filter medium 18 to be cleaned. Since it is possible to maintain the optimal conditions for breeding, it is possible to keep them for a longer period of time than before, and the water replacement cycle can be significantly extended, which has great practical effects. It is a big thing.
