Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a filtration device for an aquarium, particularly for an aquarium used for breeding ornamental fish and aquatic plants, and relates to a filtration device for water contained in the aquarium.

[0002]

[Background of the invention]

 Generally, as a filtering device for the above-mentioned aquarium, a filter mat such as a sponge is laid on the bottom of the aquarium, and a filter material such as gravel is laminated on the surface, or a hollow case placed in water. It is known that the inside is filled with a filter material such as cotton.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventionally known filtration device, the filtration of dusts cannot be said to be sufficient, and over time, water tends to become turbid, and microorganisms such as phytoplankton cannot be filtered. Therefore, moss, algae, etc. will adhere to the inner surface of the aquarium. As a result, it is necessary to clean and replace the filtration device and the water tank itself in a relatively short cycle.

[0004]

[Purpose of the invention]

 Therefore, the present invention has been made by paying attention to the above-mentioned conventional circumstances and problems. By solving these problems, it becomes possible to filter water in a water tank even with finer impurities, and its effective As it is capable of lengthening the time and filtering microorganisms, it can prevent moss and algae from adhering to the inner surface of the aquarium and maintain a clear and transparent state. The present invention is characterized in that it provides a filtration device for such an aquarium.

[0005]

[Means for Solving the Problems]

 In order to achieve this object, the aquarium filtration device according to the present invention has a pleated and tubular paper filter, and a pump is connected to at least one end surface of the paper filter through a joint. The paper filter is equipped with a liquid-containing material such as felt or sponge, and the liquid-containing material is coated and impregnated with a microbial filter agent. It is said that.

[0006]

[Action]

 With the above configuration, the water in the water tank that is forced to flow by the pump comes into contact with the pleated paper filter, so that the contact area is very large and the filtration efficiency is increased. By providing the material on the outer surface of the paper filter, it is possible to filter the microorganisms that cause moss and algae, and keep the water in a clear and clean state for a long time. Cleaning and replacing the paper filter should be done at long intervals.

[0007]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a side view showing a filtration device for an aquarium embodying the present invention, FIG. 2 is a front view of the same filter section, FIG. 3 is a plan view of the same with a cap removed, and FIG. 4 is a plan view of the same cap. FIG. 5 is a side view showing a second embodiment with an upper part added, FIG. 6 is a plan view showing the same, FIG. 7 is a front view showing a third embodiment, and FIG. 8 is a view showing a fourth embodiment. It is a front view shown.

In these figures, reference numeral 1 shows a water tank formed of a transparent material such as glass or acrylic. A casing 2 is provided near the top opening of the water tank 1, and known casings such as felt, cotton, and activated carbon are incorporated in the casing 2 to form a known filter.

Further, the inner end of the casing 2 described above has a slit, a small hole, or a mesh structure and is in communication with the water supply unit 5.

A final filtration water passage 6 having a slit, a small hole, or a mesh structure is also formed in the water delivery portion 5, and the drainage pad 6 with the water inlet facing the filtration water passage 6 is formed. Ip 7 is provided.

On the other hand, reference numeral 8 in the figure denotes a filter section. The filter section 8 mainly uses a paper filter 9, and the paper filter 9 is bent in a pleat type and is formed into a cylindrical shape by being rolled.

In this embodiment, the inner surface of the above-mentioned paper filter 9 is provided with a mesh tubular body 10 that serves both as water passage and shape retention as a core material. Further, a liquid-containing material 11 such as felt or sponge is provided on the outer periphery of the paper filter 9, and the liquid-containing material 11 is coated and impregnated with a liquid microorganism filter agent.

An upper cap 12 is attached to the upper end of the paper filter 9 and a lower cap 13 is attached to the lower end of the paper filter 9 to retain the shape of the paper filter 9. The upper cap 12 has a connecting portion at its center. 14 is formed, and the connecting portion 14 connects with the joint member 15.

The joint member 15 is at least a three-way joint, one of which is connected to the submersible pump 16 and the other of which is connected to the water supply pipe 17 for supplying water into the casing 2.

The filtering device for the aquarium according to the first embodiment is configured in this way. The action is to operate the submersible pump 16 so that water is sent from the filter section 8 through the joint section 15 and the water supply pipe 17 to a known filter in the casing 2, and the filtration water passage section 6 of the water supply section 5 is supplied. The circulation through the drainage pipe 7 to the inside of the water tank 1 is continuously performed.

Therefore, the liquid-containing material 11 of the filter part 8 filters microorganisms and the paper filter 9 filters physical dust, and the water filtered by the filter part 8 is further filtered by the filter in the casing 2. The filtration and water passage section 6 is also overlaid for filtration.

Further, FIGS. 5 and 6 show a second embodiment of the present invention, and the portions common to the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted. In the case of the second embodiment, instead of the known filter in the casing 2, there is a complete upper filtration structure in which the filter part 8 having the same structure as that described above is horizontally arranged, and the joint part 15 is submerged in water. A typical strainer 18 to be installed is attached. Incidentally, reference numeral 4 in the figure is a filter material for further filtering the water from the filter portion 8.

That is, in the second embodiment, the strainer 18 performs the filtration as the first step, and then the filtration of the microorganisms by the filter unit 8 and the physical dust filtration are performed. The water is to be circulated in a cycle through the filtration water passage unit 6.

In the second embodiment, as shown in FIG. 6, the water supply pipe 17 is branched and sent to the two filter units 8 arranged in parallel so that the water supply pipe 17 becomes larger at a time. The amount of water can be filtered, and the structure can be adapted to the size of the water tank 1.

Further, FIG. 7 shows a third embodiment of the present invention. In the third embodiment, the filtering device is a vertical type, and a water suction port 20 is formed on the bottom side of the casing 19. The partition plates 21a, 21a of the filter medium 4 are formed in the bottom of the casing 19 to form a storage chamber 21 through which water can pass, and above the storage chamber 21, the filter unit 8 having the same configuration as described above is provided. 19 is attached to the lid 22 in a suspended state, and the drain 22 is provided which penetrates the lid 22 and communicates with the filter section 8.

According to this third embodiment, water is circulated from the suction port 20 into the casing 19, passes through the filter medium 4, the filter portion 8 and is discharged from the drain port 23. Becomes

Further, FIG. 8 shows a fourth embodiment of the present invention, and in this case also, it is of a vertical type. In this case, the lower cap 13 of the filter section 8 having the same structure as described above is directly connected to the submersible pump 16, and the water pumped up by the submersible pump 16 is sent to the filter section 8 and directly fed from the filter section 8. It has a simple structure that drains water to the inside.
