DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter device for a water tank which is installed at the bottom of a water tank for breeding ornamental fish, live fish and the like, and circulates and purifies water in the water tank.

[0002]

2. Description of the Related Art There are conventionally known various types of filtration devices which are installed at the bottom of a water tank to purify internal water. For example, JP-A-10-664
The filtration device described in Japanese Patent Publication No. 74 is provided with a filter having a receiving portion provided with a large number of water passage holes, a filtering material for covering the receiving portion to form a filtration layer, and water in the water tank being aired. Together with an air feed pipe and a water feed pipe to be sent under the filtration layer, a water purification channel provided separately from the filter, an external water supply pipe for supplying water to the water purification channel, and an inside of the water purification channel housed in the water purification channel. One or both of an aerobic filter medium and an anaerobic filter medium for filtering flowing water, and a water purification outlet capable of sending water purified inside the water purification channel to the outside are provided.

[0003]

However, in the above-mentioned conventional filtering apparatus, the inlet and outlet of water are always open. Therefore, it is good when filtering treatment by submerging in the water tank, for example, to replace the water in the water tank or to clean the gravel, or to remove and clean water algae and the like attached to the glass surface and decorations, The filter frame will be removed from the water tank. Therefore, since the water inside the filtration frame is also discharged at the same time, the filter medium dries and the attached bacteria are killed. Therefore, when the filter is placed in the water tank again, the filtration ability is not restored until the bacteria are attached. In addition, since the water in the water tank is simply passed through, not only the change is poor, but also because only the liquid pump can be used, the filtration processing capacity is constant, and the filtration processing capacity cannot be selected depending on the scale of the water tank, so that the usability is good. Absent. Therefore, even if it is taken out of the water tank, water is accumulated inside the filtration chamber and bacteria survive, and there is a demand for an easy-to-use filtration device capable of setting the filtration capacity according to the size of the water tank. I have.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the drawings. 1 is a schematic perspective view, FIG. 2 is an exploded perspective view, FIG. 3 is a longitudinal sectional view of a first use state using an air pump, and FIG. 4 is a perspective view of an embodiment installed in a water tank in the first use state. FIG. 5 and FIG. 5 are vertical cross-sectional views of a second use state using a submersible pump or a water pump, and FIG. 6 is a perspective view of an embodiment installed in a water tank in the second use state.

The filtering apparatus 1 of the present invention comprises a thin rectangular filter frame 2 formed of a synthetic resin. A filtering chamber 3 is formed in substantially the entire area of the filter frame 2, and one side of the filter frame. A water inflow portion 4 is provided in the portion, and a filtered water outflow portion 5 is provided in the other side portion.

In the filtration chamber 3, glass wool, non-woven fabric,
Filling with a filter material 31 made of natural or artificial stone or other material and easily proliferating with bacteria attached thereto, and opening and closing the upper or end face of the filter chamber 3 and other parts, thereby filtering the inside of the filter chamber 3. The media 31 can be removed and washed, or a new or washed media can be loaded.

The front and rear of the filtration chamber 3 are partitioned by water-permeable partition plates 32, 32 having a plurality of slits formed in a vertical direction, and the inflow section 4 is provided on the front side and the outflow section 5 is provided on the rear side. It is provided. Therefore, the filtration chamber 3 includes upper and lower plate portions, left and right end plate portions, and the front and rear partition plates 32.
, So that even if there is an opening / closing portion for replacement of the filter medium 31, it is sealed.

The inflow portion 4 includes a bottom portion 41 extending from the bottom plate of the filtration chamber 3, the front partition plate 32 described above,
It is configured to be surrounded by left and right end face portions 42 and an inclined front portion 44 in which thin vertical slits 43 are formed in parallel. A first opening / closing plate 46 provided with an opening / closing slit 45 in the same direction as the slit of the partition plate 32 in the longitudinal direction is slidable at least by the width of the slit of the partition plate 32. A slide knob 47 is protruded from one end to be positioned on the surface of the inflow portion 4, and the first opening / closing plate 46 is slidable by the knob 47 outside the filter frame 2.

Therefore, the first opening / closing plate 4 is controlled by the knob 47.
When the slit 6 is slid in the longitudinal direction so that the slits of the partition plate 32 are aligned with the slits 45, the water in the water tank passes through the partition plate 32 from the inflow portion 4 so that the inflow portion 4 is opened. 3 can flow. But the first
If the position of both slits is made not to coincide by sliding the opening / closing plate 46, each slit is closed, so that water does not pass through the inflow portion 4.

The outflow portion 5 is provided behind the rear partition plate 32 and is composed of an outflow frame 51 higher than the filtration frame 2. Inside the outflow frame 51, the partition plate is provided. The space portion communicates with the filtration chamber 3 through the space 32. On the upper surface 52 of the outflow frame 51, a bubble diffusion portion 53 in which a plastic net is attached to a small hole is provided.
Are provided in parallel. In addition, a second opening / closing plate 55 having a plurality of opening / closing holes 54 formed on the inner surface of the upper surface 52 so as to coincide with the bubble emitting portion 53 can be slid by at least the length of the diameter of the bubble emitting portion 53. An operation unit 56 protruding from an end of the second opening / closing plate 55 extends outside the upper surface 52.

An air pipe 57 is provided below the space of the outflow frame 51 so as to extend along the rear partition plate 32. A plurality of air discharge holes 58 formed in the air pipe 57 are provided. Is formed upward.
One end of the air pipe 57 is closed, and the other end protrudes out of the filter frame 1 and is provided with a socket 59 for connecting a tube of an air pump (not shown). Therefore, by connecting the tube of the air pump to the air pipe 57 via the socket 59 and driving the air pump, air is discharged as fine bubbles from the air discharge holes 58 of the air pipe 57, and Since the air pipe 57 rises up the space of the body 51 and flows out of the bubble diffusion part 53, the air pipe 57 constitutes a first connection part for the air pump at the outflow part.

At the left and right corners on the rear side of the filtration chamber 3, an L-shaped water-permeable partition frame 60 is provided so as to surround the left and right portions of the end of the rear partition plate 32. A water suction space 61 is formed in a portion surrounded by the inner surface of the frame body 60 and the end of the partition plate 32, and an outlet hole 62 is opened in the upper surface of the space 61, and a lid member 63 made of plastic or the like is provided. Can be opened and closed. The suction space 61 communicates with the outflow frame 51 via the partition plate 32 and with the filtration chamber 3 via the partition frame 60.

The outflow hole 62 can be provided with a pumping pipe 64 for a water pump or a submersible pump, so that the outflow hole 62 constitutes a second connection portion for the submersible pump and the water pump. .

The outflow section 5 has the above-described configuration. Next, a first use state in which the water in the water tank S is filtered using an air pump will be described with reference to FIGS. In this first use state, since the water pump or the submersible pump is not used, the outflow hole 62 is closed by the lid member 63. Then, as shown in FIGS. 3 and 4, when the tube 65 of the air pump is connected to the socket 59 and the air pump is driven in this state, air is released as air bubbles from the air discharge hole 58 of the air pipe 57. Outflow frame 5
1 rises into the space portion, and further flows into the inside of the water tank S as fine bubbles by the plastic net from the bubble discharge holes 53, so that the fine bubbles rise as a film inside the water tank S. A flowing phenomenon occurs. In the space of the outflow frame 51, the bubbles rise while suctioning the water inside the filtration chamber 3, so that the water in the water tank S is sucked from the inflow section 4, passes through the filtration chamber 3, and flows out of the outflow section 5. Return to inside. Therefore, the water in the water tank is forcibly passed through the filtration device 1 to form a circulating flow, and thus is sufficiently purified in the process of passing through the filtration chamber 3.

In particular, if the gravel J is laid on the upper surface of the filtration device 1 up to the height of the outflow frame 51, the gravel J at the front side of the inflow portion 4 is subjected to residual food debris and fish droppings. For example, physical filtration is effected because solids such as solids are forcibly removed, and bacteria adhering to the filter material 31 in the filtration chamber 3 are subjected to biological and chemical filtration based on aerobic and anaerobic effects. Due to the action of the treatment, the physical filtration, combined with the biological and chemical filtration treatments, effectively purifies and circulates the water.

In the first use state, since the air pump is used, it is impossible to supply an extremely large amount of air to the outflow portion 5. Therefore, it is not possible to expect a very high filtration treatment capacity. Therefore, it is preferable to use the method when the number of fish to be kept in the water tank is small, when raising small fish, or when the tank is small or small.

Next, a second use state in which a water pump or a submersible pump is used will be described with reference to FIGS. In this state, since the air pump is not used, the tip of the socket 59 is closed with a cap K or the like as shown in FIGS.
, And the outflow hole 62 is opened. In this case, if two pumps or submersible pumps are used, both outflow holes 62 are opened, and if one pump is used, one of the outflow holes 62 is opened.

Then, the lower end of the pumping pipe 64 is attached to the open outflow hole 62 as described above, and as shown in FIG. 6, a pumping pump P is connected to the pumping pipe 64 and driven. When the pump P is driven, the water in the suction space 61 is strongly sucked.
And the water inside the outflow frame 51 is sucked. Therefore,
The water in the water tank flows in from the inflow portion 4 and forcibly passes through the filtration chamber 3, is effectively filtered, and rises from the suction space 61 to the pumping pipe 64. The water passes through the filter device F, is filtered again, and the filtered water flows down to the water tank S.

Therefore, according to the second use state,
The water in the water tank S is physically filtered by the gravel J at the entrance of the inflow portion 4, and is chemically and biologically filtered while passing through the filtration chamber 3.
Since the pumping capacity of the water pump P is extremely large, the water in the water tank can be strongly filtered. For this reason, it can be used in a case where the size and size of the water tank are large, a case where a large number of fish are bred, and the like.

In the second use state, the pumping pipe 6
A submersible pump (not shown) can also be connected directly to 4. Then, since the water in the suction space 61 is strongly sucked by driving the submersible pump, the water in the water tank can be strongly filtered as in the case of the water pump.

In both the first use state and the second use state, when replacing the water in the water tank, the first opening / closing plate 46 is slid by the knob 47 so that the opening / closing slit 45 and the front plate 44 By making the position of the vertical slit 43 different, the inflow portion 4 is closed. In addition, the lid member 63
By closing the outlet holes 62, the operation unit 56 slides the second opening / closing plate 55 to change the positions of the opening / closing holes 54 and the bubble diffusion unit 53, thereby closing the outlet unit 5.

Therefore, in this state, the inside of the filter frame 2 is closed by closing the inflow portion 4 and the outflow portion 5, so that
The water can be taken out of the water tank S while the water remains in the filtration chamber 3. Then, after removing the filter frame 2 from the water tank, the water in the water tank can be exchanged, gravel is taken out and washed, or water algae and the like adhered to the glass and decorative materials of the water tank can be cleaned. If the filter frame 2 with water remaining after cleaning or cleaning is installed at the bottom of the water tank,
Since the filter medium 31 does not dry while being in contact with water, the attached bacteria do not die. For this reason, the filtration efficiency does not decrease even if the water tank is used as it is.

Although the present invention has been described with reference to the drawings and embodiments based on the drawings, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments unless the structure described in the claims is changed. But it can be implemented. For example,
The opening and closing mechanism of the inflow section and the outflow section is not limited to the embodiment shown in the drawing, and the specific configuration of the outflow section is not particularly limited.

[0026]

In summary, the present invention provides a filter frame having a filtration chamber filled with a filtering material inside, on one side of which is provided an inflow portion into which water in a water tank enters, and on the other side, filtered water. The filter medium chamber is made hermetic by opening and closing the inflow section and the outflow section, and a first connection section for an air pump, a submersible pump, and a water pump are provided in the outflow section. A second connection portion for use in the air conditioner, whereby any one of an air pump, a submersible pump, and a water pump can be selectively used.

Therefore, any one of the air pump, the submersible pump, and the water pump can be selectively used depending on the size of the water tank and the fish to be bred, so that an optimal filtration efficiency without waste can be obtained. And even if it is taken out of the water tank at the time of washing water or cleaning the inside, bacteria do not die because the filter material does not dry, so that the filter function can be continued immediately upon reuse,
As a freshwater fish, a saltwater fish ornamental aquarium, or an aquarium for live fish, the structure is simple and the practical value is extremely high.
