Description

Filtration Device for Aquarium}

The present invention relates to a filtration device for an aquarium, and more particularly, to a filtration device for an aquarium that generates bubbles while purifying the quality of water in a tank.

In general, a filtration device is installed in an aquarium to purify the water inside the tank. The filtration device circulates water with a pump and filters contaminants in the water by installing a filter in the water circulation path.

The filtering device is installed inside or outside the tank, and the filtering device installed inside the tank is mainly installed at the bottom or side wall of the tank.

On the other hand, in the aquarium, a bubble generator is installed along with a filtering device. The bubble generator uses an air pump to introduce external air into the water to provide oxygen to the organisms inside the tank, and to generate bubbles in the water, causing a visual aesthetic.

However, since the bubble generator requires a separate power supply and causes noise, and is installed separately from the filtering device, installation is cumbersome.

Utility Model Publication No. 92-0005675 discloses a multi-stage bubble generator for an aquarium capable of generating bubbles while filtering foreign substances in water.

Multi-stage bubble generators for aquariums generate bubbles in the part where drainage is performed, that is, in the bubble supply pipe connected to the drainage pipe, so bubbles are not easily generated depending on the depth of the bubble generation site. In other words, when water is discharged through the expansion pipe, the pressure in the pipe is lowered, and air is introduced into the air supply hose due to the pressure difference with the atmosphere, and bubbles are generated. Does not occur.

In addition, in the multi-stage bubble generator for an aquarium, it is difficult to set the depth of water so that the bubble supply pipe is close to the bottom of the tank, so the time for the bubbles to stay in the water is shortened, making it difficult to increase the amount of dissolved oxygen.

In addition, the multi-stage bubble generator for aquariums has a large wave of water when the generated bubbles are large, which adversely affects living organisms such as fish and aquatic plants, as well as bubbles bursting from the surface, causing noise, and water splashing out of the tank. .

Further, in the multi-stage bubble generator for an aquarium, since the filter is installed under the motor, it is inconvenient to disassemble and combine the filter for replacement or cleaning, and there is a problem that the entire device must be separated from the water tank.

The present invention is made by looking at the above points, and since the air for generating bubbles flows smoothly, the amount of bubbles generated can be increased, micro bubbles can be generated, and the filter for an aquarium is easy to replace and clean. To provide, has a purpose.

The filter device for an aquarium proposed by the present invention has a porous structure and is installed inside the tank to filter foreign substances as water inside the tank flows from the outside to the inside, and the filter is installed inside the filter and has a fixed side surface. A centrifugal pump having a water passing pipe in which a plurality of water passing holes are formed at intervals, a suction port and a discharge port, and suctioning water inside the water passing pipe through the suction port and discharging it through the discharge port by rotation of the impeller; and An air inlet pipe installed to allow air to flow into the suction port when water inside the pipe is sucked into the suction port, and a plurality of discharge holes connected to the discharge port of the centrifugal pump and through which water and air are discharged are spaced at regular intervals along the length direction It includes a discharge induction pipe formed every time.

The discharge induction pipe includes a vertical part forming a vertical transfer passage vertically so that water and air bubbles discharged from the discharge port of the centrifugal pump are transferred to the lower side of the water tank, and connected to the lower end of the vertical part and transferred from the vertical part. It includes a horizontal portion forming a horizontal transfer passage so that water and air bubbles are transported horizontally, and in which a plurality of discharge holes are formed at predetermined intervals along the length direction.

In addition, the present invention further includes a plurality of pallets forming a collection space inside the filtration layer installed at the bottom of the water tank, and the discharge induction pipe may be disposed in the collection space by further forming a water outlet at the end.

The pallet includes an upper plate having a plurality of water-through holes formed at a predetermined interval, a plurality of support legs formed under the upper plate and supporting the upper plate from the bottom surface of the water tank, and vertically installed under the upper plate and supporting the pallet. It is coupled between the legs and includes a plurality of side plates in which a plurality of through holes are formed.

The pallet further includes a coupling portion to be installed in succession on the same plane, and the coupling portion is coupled with an assembly protrusion formed at the corner of the upper plate, and the assembly protrusion formed at the corner of the upper plate and formed on another upper plate. Includes assembly groove.

According to the filtering device for an aquarium according to an embodiment of the present invention, since air is introduced through the inlet of the centrifugal pump, air is smoothly introduced and bubbles are well generated.

And according to the filter device for an aquarium according to an embodiment of the present invention, since the air bubbles formed by being sucked through the inlet may be split by the impeller and generate micro bubbles, the amount of dissolved oxygen in the tank can be increased and the wave of water can be reduced. It can prevent bubbles popping noise and water splashing.

In addition, according to the filtration apparatus for an aquarium according to an embodiment of the present invention, since the position at which the bubbles are discharged can be set at a deeper depth, the distance at which the bubbles float can be increased, thereby increasing the amount of dissolved oxygen.

In addition, according to the filter device for an aquarium according to an embodiment of the present invention, since the filter is installed on the upper side of the pump, it is easy to replace and clean the filter.

Further, according to the filtration apparatus for an aquarium according to an embodiment of the present invention, since a pallet is installed at the bottom of the tank and water is circulated under the pallet, it is possible to further filter water from the bottom of the tank.
