Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aquarium filter device used for purifying water in an aquarium in which fish and the like are bred.

[0002]

2. Description of the Related Art An aquarium filter device has a function of purifying water contaminated by living organisms, and various types have been conventionally known. Less than,
A conventional technique of such a filter device for purifying water in a water tank will be described.

If the water in the aquarium in which living things inhabit is left as it is, it is gradually polluted. This dirt is caused by litter such as manure of cared fish, carcasses, residual food, or dead leaves of various aquatic plants.
Nitrogen compounds such as ammonia and nitrous acid generated based on these are known to be harmful to living organisms. Therefore, in the water tank to which the filter device is not attached, unless the water is frequently changed, organisms die and the wall surface in the water tank is contaminated with algae or the like.

On the other hand, when the filter device is attached, the dirty water is purified by the following steps, for example. Usually, a filter device for purification has a filter material composed of synthetic resin wool, mat, or the like in which aerobic bacteria easily propagate.
When sewage passes through such a filter material, among aerobic bacteria, Nitrosomonas decomposes the highly poisonous ammonia into toxic nitrous acid, and Nitrobacter decomposes nitrous acid into harmless nitric acid. It has been known.
That is, the sewage is returned to the water in the water tank by being subjected to the above-described nitrification action by passing through the filter material in which aerobic bacteria have propagated.

The purifying action by such a filter device is only an example, and in addition, the filter device is provided with various substances such as activated carbon, barley stone, etc. according to the application so as to be beneficial to living organisms. It is also known to pass water through to purify water.

[0006]

However, the filter materials such as synthetic resin wool and mats used in the above-described filter device have a relatively large litter, for example, fish dung, which causes them to become visible within a short period of time. Easy to get clogged. This is because the conventional filter device is simply provided with a filter material such as synthetic resin wool or mat in a portion through which dirty water passes, and no consideration is given to the arrangement state of fibers such as wool. Because it was not.
Therefore, a layer of dirt is immediately formed on the surface of the filter material, which impedes the flow of water and necessitates taking out and cleaning the filter material in a short period of time. Such cleaning work is very troublesome for the breeder.

The present invention has been made in order to solve such a problem, and provides a filter device capable of maintaining a smooth water flow even during long-term use and facilitating cleaning work. It is an object.

[0008]

In order to solve the above-mentioned problems, the present invention provides a filter portion formed by bundling a plurality of columnar filters formed by intertwining a large number of fibers extending in the longitudinal direction. And a cylindrical outer container accommodating the filter part detachably and loaded into a pipe for circulating water in a water tank, and an extending direction of a filter which is formed in the outer container and constitutes the filter part. It has a suction port and a discharge port for connecting to the pipe so as to be arranged along the water flow direction.

Further, the present invention is a filter device for an aquarium, which is attached to a pipe for circulating water in an aquarium in which living things are bred, and is equipped with a filter portion for purifying water, wherein the filter portion is arranged in a longitudinal direction. It is configured by forming a large number of pores along the longitudinal direction in a cylindrical filter that is formed by intertwining a large number of fibers extending along the longitudinal direction of the filter portion in the direction of water flow. It is characterized by being arranged along.

Furthermore, the present invention is a filter device for an aquarium attached to a pipe for circulating water in an aquarium in which living things are bred, and the filter device is arranged at a predetermined interval along the water flow direction. And a mesh-shaped holding member that is provided between these holding members, and extends along the direction of the water flow that is provided in large numbers across each holding member so that a bypass is formed according to the size of the mesh. And a filter portion including fluffed fibers.

[0011]

Since the filter portion is constructed so that a large number of bypasses along the longitudinal direction are formed in the fibers along the longitudinal direction, the flow of water is improved and clogging is less likely to occur. That is, since the fibers along the longitudinal direction and the bypasses extend along the water flow direction, the resistance that water receives is reduced, and a smooth flow of water is ensured. Further, since the contact portion between the water and the fiber in the filter portion increases, the area where the litter adheres increases along the flow direction, and the litter can be efficiently collected. Further, since the water flow is always secured, the aerobic nitrifying bacteria are actively propagated, the water purifying action is performed more smoothly than before, and the filtration space is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the filter device according to the present invention will be specifically described below with reference to the accompanying drawings. FIG. 1 is a diagram showing a state in which the filter device is disassembled, and the filter device 1 includes cylindrical outer containers 5 and 6, and a filter portion 20 arranged in the outer containers 5 and 6. As shown in the figure, the cylindrical outer containers 5 and 6 can be separated from each other, and when both are assembled, a cylindrical inner space is formed. Each of the outer containers 5, 6 has a suction port 5a for sucking water and a discharge port 6a for discharging water.
Is formed, and the suction port 5a and the discharge port 6a are
The filter device 1 is installed by mounting it on a pipe for circulating water in the water tank. That is, the purified water flows along the longitudinal direction of the filter device 1.

A filter section 20 is removably loaded in the internal space defined by the cylindrical outer containers 5 and 6. The loading of the filter part 20 into the outer containers 5 and 6 may be performed by enclosing the filter part 20 in the outer container 5 and covering the outer container 6 which is a lid, as shown in the drawing. Alternatively, although not shown, the outer containers 5 and 6 are integrally formed to provide a door which can be opened and closed, and the door is opened to open the filter unit 2
The configuration may be such that 0 is enclosed in the outer container.

The filter portion 20 is formed by bundling a plurality of filters 25, which extend in the longitudinal direction and are formed in a cylindrical shape, into a cylindrical shape as a whole.
Each filter 25 is configured by intertwining a large number of fibers extending along the longitudinal direction, and specifically, is configured by collecting and arranging wavy fibers along the longitudinal direction as shown in FIG. ing. FIG. 3 is a diagram showing the fibers constituting the filter 25 in an enlarged scale of about 150 times,
As is clear from this figure, the respective fibers extending in a wave shape are entangled with each other to constitute one filter extending in the arrow direction. In this case, the respective fibers of the filter may be entangled so that the finally formed filter extends in the longitudinal direction as a whole even if the fibers are not wavy. Therefore, even if each fiber is not wavy in advance, one filter may be configured by bundling, for example, a plurality of linear fibers in a spiral intertwined manner.

A cylindrical filter portion 20 shown in FIG. 1 has a length of about 9 cm and a diameter of about 8 mm.
Forty-eight of them are integrally bundled. When the filter unit 20 is configured in this manner, a large number of bypasses 30 are formed between the filters 25 along the extending direction of the filters as shown in the figure. In this case, forming a large number of bypasses 30 in the filter section 20 is an essential item for the present invention. By forming this bypass section, the filter section does not become clogged and dirty water can be collected. It becomes possible to purify. In order to form such a bypass 30, in the case of the filter 25 having a cylindrical shape as shown in the drawing, it is formed by bundling at least three or more filters and loading them in a cylindrical outer container. Of course, the number and size of the bypasses can be adjusted according to the number of filters to be bundled and the diameter of the filter 25 according to the organism to be raised.

In practice, when the filter device 1 thus constructed is attached to an aquarium in which ornamental fish and the like are bred, the following actions and effects are obtained. As shown in FIG. 1, the bypass 30 formed by bundling a large number of filters 25 and the fibers entangled along the longitudinal direction forming each filter 25 improve the flow of water and prevent clogging. Less likely to happen. That is, since the fibers of each filter 25 and the bypass 30 extend along the flow direction, the resistance that water receives is reduced, and since the contact portion between the water and the fibers in the filter portion increases, the litter of the litter is increased. The amount of the adhered region increases correspondingly along the flow direction, and the litter 35 can be collected efficiently.
Usually, the relatively large litter 35 flows in the bypass 30 due to the pressure of the flowing water, and adheres to the filter 25 of the part in the bypass 30. In this case, a certain bypass may cause clogging due to a relatively large litter, but the flow of water is secured by a large number of other bypasses formed, so that the entire filter unit 20 is closed within a short period of time. It does not clog. Moreover, even small litters are deposited in the fiber region along the flow direction within this bypass and within each filter 25. A smooth flow of water is ensured by the plurality of bypasses and the arrangement of fibers in each filter along the water flow direction.

Further, the filter unit 2 having the above structure
According to 0, since the contact area with the flowing water increases, the purification effect can be further enhanced by mixing in advance a substance effective for purifying water, that is, a substance useful for the living organisms. Will be possible. The example will be specifically described below.

For example, if each filter 25 is preliminarily mixed with minerals, fertilizers, etc., nutrients can be easily and effectively supplied to the aquatic plants growing in the aquarium. Alternatively, if aerobic bacteria are mixed in advance, the nitrification action of water can be effectively promoted. Alternatively, if an adsorbent such as activated carbon is mixed, impurities can be effectively adsorbed. As described above, by appropriately selecting a substance that purifies water according to the fish to be bred and mixing it in the filter unit 20 in advance, the water quality in the aquarium is stable, and the living body is stable and promotes growth. Can be achieved. Further, due to such a purifying action, generation of algae and the like can be suppressed, and the cleaning work of the water tank can be reduced.

Incidentally, the filter portion 2 of such various substances
Various modes are conceivable as a method of mixing 0. For example, the filter unit 20 may be configured by bundling a large number of filters in which different substances are mixed,
The filter section 20 may be divided into blocks along the flow direction at regular intervals, and different substances may be mixed in each block.
Alternatively, a plurality of filter devices 1 may be installed in a pipe through which water flows, and different substances may be mixed in each filter device. Alternatively, these mixing methods may be combined appropriately.

The filter 25 or the filter section 20 described above can be easily removed from the outer containers 5 and 6 and replaced, so that the cleaning operation of the filter device itself is extremely easy and the filter device is installed in the water tank. Since it may be arranged in a part of a pipe for circulating water, it is possible to simplify the production of the water tank.

Next, a second embodiment of the filter device according to the present invention will be described with reference to FIG. In this figure,
(A) is a figure which shows the longitudinal cross section of the filter apparatus 1a which loaded the filter parts 20a, 20b, and 40, (b)-.
(D) shows the filter units 20a, 20b and 4 respectively.
It is a top view which shows the structure of 0. In the filter device 1a, cylindrical filter parts 20a, 20b and 40 are sequentially loaded in a cylindrical outer container 16 having a discharge port 16a along the flow direction of water, and a suction port 15a is formed. It is configured by covering a lid-shaped outer container 15.

First, the filter section 20a will be described. The filter unit 20a is the filter 25 shown in FIG.
Similarly to the above, the filter 25a configured by intertwining a large number of fibers extending along the longitudinal direction serves as a matrix. In this filter 25a, along the longitudinal direction (water flow direction),
Many holes 30a are formed, and many holes 30a are formed.
However, it plays the same role as the bypass 30 of the embodiment shown in FIG. That is, since the fibers of the filter 25a and the bypass 30a extend along the flow direction, the resistance that water receives is reduced, and the contact portion between the water and the fibers in the filter portion increases, so that the litter adheres. The area increases accordingly along the flow direction, and the litter is efficiently collected. In this case, with a relatively large litter,
Although some bypasses may become clogged, many other bypasses ensure water flow.

On the downstream side of the filter portion 20a, a filter portion 20b having a similar structure is mounted. Like the filter portion 20a, the filter portion 20b has a filter 25b, which is formed by intertwining a large number of fibers extending in the longitudinal direction, as a base body, and has a diameter smaller than that of the hole 30a along the water flow direction. A large number of holes 30b are formed. As described above, since the relatively large litter is collected by the filter unit 20a, such a large litter never reaches the filter unit 20b.
Even if the diameter of the hole 30b is reduced, clogging does not occur. On the other hand, a small litter may not be collected at this portion as it passes through the hole 30a of the filter portion 20a. Therefore, by arranging the filter portion 20b having a similar structure in which a large number of small-diameter holes 30b are formed on the downstream side of the filter portion 20a, the litter that could not be collected by the filter portion 20a can be efficiently collected.

In the embodiment shown in FIG. 4, this filter unit 2
Further, another filter unit 40 is arranged on the downstream side of 0b. As described above, since the litters of various sizes are collected by the filter units 20a and 20b, the filter unit 4a
At 0, litter that normally causes clogging does not flow. That is, even if a filter having a normal structure or a filter having a finer mesh is provided in this portion, the flow of water due to clogging does not stop. Therefore, it is possible to arrange filters of any configuration in this portion. For example, a filter having a larger number of smaller diameters than the holes 30b shown in (c) may be arranged in the same matrix as the filters 25a, 25b, or as shown in (d), the filters 25a, You may arrange | position the filter 25c with the same base | substrate as 25b, and the hole is not formed.

As shown in FIG. 4, filter portions 20a and 20b each made of a cylindrical filter having holes previously formed therein.
According to this, compared with the filter section 20 shown in FIG. 1, handling becomes easier and it becomes possible to easily form bypasses of various sizes.

The above-described embodiment shown in FIG. 4 is merely an example of the filter device, and various modifications can be made. Hereinafter, modified examples included in the scope of the present invention will be described. (1) In the embodiment shown in FIG. 4, the filter parts 20a and 20b having different configurations are arranged along the flow direction, but like the configuration shown in FIG. 1, the filter part 20a or 20b is a single outer container. You may load in 15 and 16 and may comprise a filter apparatus. In this case, of course, if you install a filter device in which different filter parts are loaded in series on the pipes through which water circulates, you can replace the filter part of any filter device as needed, so cleaning work , The work for purification (work of mixing bacteria etc. as necessary) can be performed more easily. (2)
The length of the filter portions 20a, 20b, 40 or the diameter of the bypass formed therein can be changed as necessary. (3) In the embodiment shown in FIG. 4, the filter portion 40 arranged at the bottom is configured to be locked by the stopper member 16c formed on the inner peripheral surface of the outer container 16. It is also possible to provide a net-like member in advance and place the filter portions 40, 20b ... On the net-like member in order. (4) Each filter section 20a, 20b, 40
Various substances can be mixed in advance in the same manner as in the above embodiment. (5) For example, the filter section 20a shown in FIG. 4 may be replaced with the filter section 20 shown in FIG.
Such a filter device may be attached in series to a pipe through which water circulates. Modifications such as the above, depending on the organisms bred in the aquarium, the installation conditions of the aquarium, the manner of use, etc.
Various adjustments are made.

FIG. 5 shows a third embodiment of the filter portion mounted on the filter device. In the filter portion 20c of this embodiment, fibers 55 extending in the longitudinal direction are attached to the intersections of the holding members 50 between the two holding members 50 having a large number of meshes as shown in (b). It is configured, and as shown in (a), it is arranged along the flow direction of the water indicated by the arrow. According to this configuration, the holding member 50
The mesh portion of the above plays the same role as the bypass portion of the above-described embodiment. That is, a relatively large litter passes through the mesh (bypass) 53 and is collected by the fibers 55 extending in the longitudinal direction inside the mesh. The diameter of the bypass 53 can be adjusted by the size of the mesh of the holding member 50 or the thickness of the fibers arranged. In this case, each fiber 55 extending along the longitudinal direction is
As shown in (c), it is formed in a fluffy state in advance, and has a structure in which litter easily attaches. Also,
Leaving each fiber 55 loosely twisted, as shown in (d), causes a flow of water within each fiber to allow a smaller litter to adhere.

Since the fibers 55 are attached between the holding members 50 at the intersections of the holding members 50 as described above,
Since it can be expanded and contracted in the direction shown by the arrow (a), the filter portion 20c itself can be cleaned extremely easily. In other words, according to this configuration, it is possible to reuse it many times by cleaning instead of being disposable. Further, the filter portion 20c may be loaded in an outer container of the filter device, or may be arranged so as to be suspended in a pipe through which water circulates, which facilitates handling. Furthermore, if the fiber 55 is reciprocated so as to be hooked on the mesh portion of each holding member 50, it becomes possible to form the filter portion 20c with one long fiber.

Of course, with respect to the embodiment shown in FIG. 5, it is possible to directly apply the modified example as described in the above-mentioned embodiment, and it is also possible to use it in combination with the filter section of the above-mentioned embodiment. Is.

Although the aquarium filter device according to the present invention has been described above, the present invention is characterized by the filter portion loaded inside the main body of the filter device, and the shape of the outer container for accommodating it. The configuration can be changed as appropriate.
