Description

The present invention relates to an apparatus for removing filth from breeding water in an aquarium, and more particularly to an apparatus for removing filth such as protein, excrement, and waste products generated in an aquarium.

When raising ornamental fish in an aquarium, if you leave uneaten the ornamental fish, excrement, waste products, or proteins generated from bacteria inhabiting the aquarium, it will be decomposed into nitrite due to the nitrification of bacteria. Even a small amount of this nitrous acid is harmful to the ornamental fish, it is desirable to remove it from the breeding water before the protein is decomposed.

In order to remove the above-mentioned protein, the conventional purification device has been reduced in size, but it causes salt dripping (salt damage) and the discharged dirt tends to become full in the main body, or the place where it is placed The space efficiency of the water tank was poor, and the scenery of the entire aquarium could be damaged, leading to results that did not meet the original purpose of ornamental use.

Therefore, conventionally, the water is forcibly circulated with a power-driven submersible pump to generate a water flow that descends into the container, and the bubbles are lifted against the water flow to efficiently remove filth, and An ornamental fish filth removal device that sufficiently aerated water has been proposed (see Patent Document 1).

This ornamental fish filth removal device is connected to a filth disposal container, a power-driven submersible pump, a water supply pipe for feeding the breeding water in the aquarium pumped up by the submersible pump, and an upper end of the water supply pipe A drain pipe for draining the sucked breeding water into the container, a drain pipe for returning the breeding water drained in the container from the bottom of the container to the drain pipe, and an air pump from the bottom of the container through the air hose. It consists of an air stone that supplies fine bubbles and a foam cup installed at the top of the container.

According to this configuration, a water flow is formed in the container from the discharge port of the drain pipe toward the drain pipe at the bottom of the container. At this time, the air bubbles supplied from the air stone rise and float in the container against the water flow, so that there is a dead water area in which the breeding water is caught under the bubbles, and in this dead water area, filth such as proteins of the breeding water is generated. Adhere to bubbles. The bubbles attached with the filth rise to the foam cup, but the bubbles attached with the filth are concentrated because they are pushed up by the subsequent bubbles and rise.

In addition, since the said container was comprised with the air stone holder and the cylinder and the air stone holder was comprised so that attachment or detachment was possible, replacement | exchange of an aeration part and cleaning became easy.

In addition, since the container can be installed at the place where the pump for the upper filtration device for ornamental fish installed at the upper part of the aquarium is installed, it can be arranged efficiently without damaging the scenery. became.
JP-A-9-238592 (Claims 1 to 3, paragraph number 0016 to 0028 on page 4)

As in the above prior art, in the device that removes the filth by generating bubbles and attaching the filth to the bubbles, the water flow that takes in the breeding water outside the main body and the filtered water inside the main body can be efficiently discharged. is important.

In the above prior art, since an electric power driven submersible pump is used to form a water flow for taking in breeding water, it is necessary to perform wiring from the inside of the water tank to the outside of the water tank, and the installation work of the apparatus is not easy. .

In addition, compared with the conventional purification device, although the size of the device could be reduced, the water supply pipe and the drain pipe had to be accommodated in the container, and the entire container was still large. . In particular, in a small aquarium water capacity 30 liters class, installing a conventional remover, appearance, since become occupied removal device considerable space, narrowing the habitat area of the ornamental fish, it has resulted in impairing the appearance It was.

Furthermore, in order to reduce the size of foam cups that store protein and other filth, if the volume is reduced, the frequency of cleaning increases, and if the frequency of cleaning is reduced, the capacity must be increased. Therefore, there was an inconvenience that the aesthetic appearance was impaired.

In the conventional removal apparatus, the foam cup can be disassembled in order to facilitate maintenance such as cleaning, but as a result, the disassembly and assembly of the foam cup and the container (aeration part accommodating portion) are repeated each time cleaning is performed. There is a disadvantage that the maintenance work becomes troublesome.

The conventional removal device is composed of the submersible pump, the container, the foam cup, the water supply pipe, the water supply pipe, and the drain pipe accommodated in the container, and has a problem that the number of parts is large, the structure is complicated, and the cost is high. was there.

Therefore, in view of the above problems, the present invention has an object to provide an aquarium filth removal apparatus that is easy to install and maintain without impairing the processing capacity of a conventional filth removal apparatus, and that is smaller and less expensive. And

To solve the previous SL problems, aquarium waste removing apparatus according to the present invention, a container for taking the rearing water in the water tank, a foam supplying bubbles shaped air into the container, the air in the foamed material and air supply means for supplying, prior Symbol surface active action of bubbles supplied from the foam, aquarium soil removal device having by adhering bubbles filth breeding water and an outlet port for discharging the waste out of the water tank a is, before Symbol containers, one longitudinal end is opened as an open end, the other end is elongated tube which is closed by a removable sealing means as the closed end, before Symbol outlet, before Symbol provided in a container upper portion including a closed end, before Symbol vessel was allowed to settle to the rearing water from the open end side to a predetermined position, by protruding the front SL container top on the water surface, the inner wall surface of the container upper And a space partitioned by the water surface. Comprising a fixing means for fixing the container to the foam, in order to supply air bubbles floats from the container bottom comprising a pre-Symbol open end toward the space, is placed in the container bottom, container side The non-foaming portion and the porous foaming portion are alternately formed in the circumferential direction of the container on the surface facing the surface, and the surface not facing the inner surface of the container is a non-foaming portion. To do.

By the container in an elongated tube, the levitation forces of bubbles supplied from the foam, is formed water flow to rise in the container, in the space partitioned by the inner wall surface and the water surface of the container top in accordance with the water flow Bubbles attached with filth are sequentially sent by buoyancy and pressure is applied, so the bubbles attached with filth are concentrated and discharged from the outlet to the outside of the water tank. Also, by providing two types of parts, a foamed part and a non-foamed part, on the surface facing the inner surface of the container of the foam material, it becomes easy to take in the breeding water in the aquarium even if the container is an elongated tube .

Furthermore, if the surface area of the non-foamed part is formed larger than the surface area of the foamed part on the surface facing the container inner side surface of the foamed material, the intake of breeding water becomes smoother.

A part of the foamed material may be exposed outside the container from the open end and installed in the lower part of the container. According to this configuration, since a water flow is formed from the outside of the container to the inside of the container, the breeding water can be taken into the container more efficiently. Note that the degree of exposure of the foam material is within a range in which bubbles are not released out of the container.

The cross-sectional diameter of the container top, be formed to be smaller than the cross-sectional diameter of the container bottom, front Symbol concentration rate of bubbles of wastes deposited increases in space.

In order not to form the corners with a level difference between the pre-SL container top and the container bottom, container tapered shoulder portion gradually reduced in diameter from the container bottom until a predetermined sectional diameter What is necessary is just to provide in upper part.

It is necessary for the septic removing device for aquarium according to the present invention to fix the container at a position where the upper part of the container is projected on the water surface. Therefore, before Symbol fixing means may be of such a fixing is a mounting means capable. In this case, the water surface position of the water tank is different by a user, the attachment means may be Re to as having an adjusting means capable of adjusting the fixed position by the position of the water surface of the aquarium. Installation work of Installing with means may be a structure as can be done by breeding water outside.

Prior Symbol closed end may be one which is integrally molded with the container body but, given the ease of container interior cleaning, closed end, an open end as container body, in order to close the open end In addition, it is preferable to close by a removable sealing means.

Waste discharged from previous SL outlet may be stored in the waste storage tank to be installed outside the aquarium. The discharge pipe connecting the discharge port and the filth storage tank may be provided with a cut portion from a predetermined position to a tip of a part housed in the filth storage tank, and the tip may be formed in a branched shape. When filth (polluted water) accumulates up to this notch, the pressure of discharging the polluted water from the discharge port is pushed back by the water pressure of the polluted water, and the discharge is stopped, so the polluted water overflows from the filth storage tank Can be prevented.

As is clear from the above description, the septic removal device for aquarium according to the present invention does not use a power-driven submersible pump to take in the breeding water in the aquarium into the device (container), and buoyancy of bubbles. Therefore, there is an effect that it can be easily installed without requiring installation work such as wiring.

In addition, compared to conventional products, the number of parts can be reduced, the cross-sectional diameter is made smaller toward the upper part of the container, the waste is not stored in a part of the container body, and is discharged to an external storage tank. By storing the air supply pipe in the container, there is an effect that the size can be drastically reduced as compared with the conventional product.

Furthermore , as a result of suppressing the number of parts, an effect is provided that it can be provided at a lower cost than conventional products.

Referring to FIG. 1, reference numeral 1 denotes an elongated tube container that constitutes a main body of an aquarium waste removal apparatus according to the present invention. The container 1 has a container lower part 1a and a container upper part 1b, and in the present embodiment, the container upper part 1b is formed to have a smaller cross-sectional diameter than the container lower part 1a.

Between the container lower part 1a and the container upper part 1b, since the cross-sectional diameters of both differ as described above, a container shoulder 1c is formed. In this case, the container shoulder 1c may be formed by a step, but in the present embodiment, the container shoulder 1c is such that the cross-sectional diameter of the container lower part 1a gradually decreases toward the container upper part 1b. It is formed in a taper shape. By providing such a tapered inclined, because corners are not formed, dirt Ri is unlikely to adhere, become even dramatically easier cleaning.

The upper end in the longitudinal direction on the container upper part 1b side is a closed end 1d, and the lower end in the longitudinal direction on the container lower part 1a side is an open end 1e.

In the present embodiment, the container 1 itself is formed in a bottomless cylindrical shape with both ends in the longitudinal direction being open ends, and the upper end in the longitudinal direction on the container upper portion 1b side is sealed with a cap 2 described later, thereby closing the end 1d. However, the present invention is not limited to this form, and the closed end 1d may be formed in a bottomed cylindrical shape integrally formed with the container 1 itself. In any form, the container upper portion 1b is blocked from the outside air by the closed end 1d, so that the container upper portion 1b is always kept in a wet state, and the filth is prevented from drying and adhering to the container 1. Can do. In addition, the material of the container 1 is not limited.

A discharge port 1f is provided on a side surface in the vicinity of the closed end 1d of the container upper portion 1b. In the present embodiment, the discharge port 1f has an opening on the side surface and a cylindrical protrusion provided from the opening in order to join a discharge pipe 5 described later. In the present embodiment, the diameter of the discharge port 1f is formed to be considerably smaller than the cross-sectional diameter of the container upper portion 1b.

As described above, the closed end 1d is tightly plugged at the open end by the cap 2. The cap 2 is provided with an air pump and an air supply pipe in order to supply air (air) from the air pump (not shown) installed outside the container to the foamed material 4 through the air supply pipe 3 inside the container 1. A coupling pipe 2a to be connected is inserted. The cap 2 only needs to be capable of sealing the open end, and the material is not limited.

The foam material 4 is made of a porous material and has a foamed part and a non-foamed part. In the present embodiment, the foam material 4 is a polyhedron (cuboid), and four side surfaces in the longitudinal direction are alternately formed on the foam surface 4a and the non-foam surface 4b. The foam material 4 is installed at a position where the four side surfaces in the longitudinal direction face the inner side surface of the container 1. Although not shown in the drawings, the four side surfaces in the longitudinal direction have a surface area of the non-foamed surface 4b larger than that of the foamed surface 4a. In addition, let the surface which does not oppose the inner surface of the container 1 be a non-foaming part.

The foam material 4 and the air supply pipe 3 are connected via a connection portion 4c. The foam material 4 supplies bubbles in the container 1 from the vicinity of the open end 1e of the container lower part 1a toward the container upper part 1b. Therefore, the foam material 4 is installed in the vicinity of the open end 1e. 4. Install so that the lower end is exposed outside the container 1 from the open end 1e. The degree of exposure of the foam material 4 is a range in which bubbles are not released outside the container 1.

The discharge pipe 5 joined to the discharge port 1f is introduced into the storage tank 6 for storing the waste discharged from the drain port 1f. In the present embodiment, the discharge pipe 5 uses a flexible pipe such as a hose or a tube. The discharge pipe 5 may be provided with a cut portion 5a so that the tip portion branches from a predetermined position of the portion housed in the storage tank 6 to the tip 5b. By providing the cut portion 5a, when filth (polluted water) is accumulated up to the cut portion 5a, the pressure of discharging the polluted water from the discharge port 1f is pushed back by the water pressure of the contaminated water, and the discharge is stopped. The contaminated water can be prevented from overflowing from the storage tank 6.

In addition, by causing the tip 5b of the water distribution pipe 5 to reach the inner bottom surface of the storage tank 6, the waste discharged from the discharge port 1f is guided by the cut portion 5a and reaches the bottom surface, so that it is stored from the tip of the water distribution pipe 5. It is possible to prevent the filth from dripping into the tank 6 and to mute the sound.

The container 1 can be fixed to the water tank by the fixture 7. In order to use the apparatus according to the present invention by floating (projecting) the upper part 1b of the container at a position above the water surface of the aquarium, the container 1 must be fixed to the aquarium and positioned. Therefore, the apparatus according to the present invention may include an attachment 7 that fixes the container 1 to the water tank at a predetermined position.

FIG. 2 is an enlarged view of the fixture 7. The attachment 7 has a container holding part 7 a that holds the container 1. The container holding part 7a is formed in a ring shape into which the container lower part 1b can be loosely inserted.

An O-ring 7b made of a stretchable elastic body is fitted to the container lower part 1b, and the outer peripheral surface of the container lower part 1b is slid and attached to a position to be fixed by the container holding part 7a, and the container is held from the open end 1e side. When penetrating through the portion 7a, the mounted O-ring 7b is locked in a state of being placed on the container holding portion 7a, and the container 1 can be fixed at a desired position.

The clamping part 7c which clamps the wall surface of a water tank is formed in the U-shaped plate-shaped body comprised from the upper side by the side view, a lower side, and the joint side which couple | bonds an upper side and a lower side. In this embodiment, by making the length of the lower side longer than the length of the upper side and inclining the lower side toward the upper side, the width gradually decreases from the coupling side toward the open end side of the upper side and the lower side facing each other. It is formed to be narrow. The clamping part 7c has an elastic force with respect to a force that pulls the lower side away from the upper side.

In a state where the holding portion 7c is rotated approximately 90 degrees counterclockwise from the U-shaped state in a side view, the upper surface outer portion forming the upper side is fixed to the outer surface of the container holding portion 7a. . In the present embodiment, the upper end of the upper side and the lower end surface of the container holding portion 7a are fixed so as to be flush with each other.

The sandwiching part 7c is provided with a height adjusting part 7d for adjusting the height to be installed between the upper edge part of the water tank wall surface and an angle adjusting part 7e for adjusting the angle to be installed between the water tank wall surface. Yes.

In the present embodiment, the height adjusting portion 7d is screwed and penetrated in a direction substantially orthogonal to the coupling surface from the outside of the coupling surface toward the inner space surrounded by a U-shape. Further, the angle adjusting portion 7e penetrates by screwing a screw in a direction substantially perpendicular to the lower side surface from the outside of the surface (lower side surface) constituting the lower side in the side view toward the inner space surrounded by the U-shape. I am letting. Further, a fixing auxiliary portion 7f made of a suction cup for auxiliaryly fixing the clamping portion 7c to the water tank wall surface in a direction facing the surface (upper side surface) constituting the upper side in the side view is provided at the front end portion of the lower side surface. Is provided. However, in actuality, since the length of the lower side is longer than the length of the upper side as described above, the upper side surface does not reach the front surface facing the fixing auxiliary portion 7f.

An L-shaped hooking portion 7g for hooking the discharge pipe 5 is provided on the upper portion of the angle adjusting portion 7e. Note that the latching portion 7g may be formed in a ring shape so as to fasten the discharge pipe 5 passed through the ring (not shown).

The attachment 7 is in a state where the container upper part 1b (including the container shoulder 1c) is floated on the water surface so that a space partitioned by the inner wall surface of the container upper part 1b and the water surface of the aquarium can be formed. As long as it can be fixed, the configuration is not limited to that shown in FIG.

Hereafter, the installation method of the filth removal apparatus for water tanks concerning this invention and the effect | action which removes filth are demonstrated using FIG. In addition, about the site | part which is common in FIG.1 and FIG.2, the same code | symbol is attached | subjected and description is abbreviate | omitted.

First, the installation method will be described. After pouring the breeding water W into the aquarium T to a desired height, the fixture 7 is fitted so as to sandwich the aquarium wall surface from the open ends of the upper and lower sides of the clamping portion 7c.

When the container 1 is penetrated from the open end 1e side to the container holding part 7a and submerged in the breeding water W in the water tank T, the water level of the breeding water in the container 1 is the breeding water W outside the container 1. The water surface S of the container and the container shoulder 1c are fixed at positions substantially coincident with each other in the vicinity of the lower end.

Since the container holding part 7a can be inserted into the container 1 as described with reference to FIG. 2, in order to fix the container 1 at the predetermined position, the container lower part 1b is fitted with an O-ring 7b. What is necessary is just to slide the outer peripheral surface of and attach to a predetermined position. Since the mounted O-ring 7b is locked in a state of being placed on the container holding portion 7a, if the O-ring 7b is mounted at an arbitrary position, the container 1 is fixed at an arbitrary height. It becomes possible.

The mounting position of the O-ring 7b is mounted from the outside of the water tank T at the above-mentioned fixed position by rough measurement, and the fine height adjustment is performed by inserting or removing the screw of the height adjusting portion 7d. Turn to the adjustment. That is, by inserting the tip of the screw into the inner space surrounded by the U-shape described in FIG. 2 and bringing the upper edge of the water tank wall and the tip of the screw into contact with each other, Since the clamping part 7c moves up and down by the rotation to the height, the height can be adjusted.

Since the amount of breeding water W that fills the tank T varies depending on the preference of the breeder, the height of the water surface is not constant. Therefore, a mechanism for adjusting the height of the container 1 is required as described above.

When the height of the attachment 7 is determined, the suction cup of the fixing auxiliary portion 7f of the attachment 7 is adsorbed and fixed to the water tank wall surface. At this time, it is preferable to sink the container 1 in a direction orthogonal to the water surface. Therefore, the angle adjustment unit 7e may be adjusted by turning the screw in either the insertion or removal direction. In other words, the screw tip of the angle adjusting portion 7e may be protruded toward the inner space surrounded by the U-shape described in FIG. 2, and the screw tip and the water tank wall surface may be brought into contact with each other for adjustment.

The discharge pipe 5 attached to the discharge port 1f can be installed so as to hang down in parallel with the container 1 by being hooked on the discharge pipe hooking portion 7g, so that it is discharged from the discharge port 1f. The filth can be smoothly delivered into the storage tank 6.

As described above, the installation method of the apparatus for removing filth for aquarium according to the present invention enables positioning of the container 1 reliably and simply, and is complicated even when the container 1 is taken out during maintenance such as cleaning of the container 1. Further, when the container 1 is installed in the water tank T again after maintenance without disassembling work, it can be easily positioned at the same height as before removal.

Moreover, since all the installation work of the attachment tool 7 can be performed outside the water tank T, it is freed from the installation work performed by putting a hand in the breeding water W, and each part of the attachment tool 7 is water in the water tank. (Especially seawater) will not corrode. Furthermore, the suction cups are not detached from the breeding water W, and the container 1 does not float.

Next, the effect | action which removes filth is demonstrated. Air is injected in the direction of the arrow in the figure from an air pump (not shown). The air pump may be a known one, but is preferably one that can control the flow rate. The injected air is sent to the air supply pipe 3 through the joint pipe 2a. Air is supplied from the air supply pipe 3 to the foamed material 4 via the connecting portion 4 c of the foamed material 4.

When bubbles B are generated from the foam material 4 and the bubbles B continuously rise from the vicinity of the open end 1e toward the container upper portion 1b, a water flow is formed in the container 1 along the flow of the bubbles B, The breeding water W is taken into the container 1 from the outside of the container 1.

As described with reference to FIG. 1, the foamed material 4 is provided with a foamed part and a non-foamed part, so that the water flow in the intake direction of the breeding water W passing between the foamed part and the inner surface of the container 1, and non-foamed Smooth circulation with the water flow in the discharge direction of the breeding water W passing between the part and the inner surface of the container 1 becomes possible.

In the present embodiment, the foam material 4 is formed in a rectangular parallelepiped shape, and the four side surfaces in the longitudinal direction are alternately formed on the foam surface 4a and the non-foam surface 4b. The upper surface and the bottom surface of the foam material 4 are non-foamed surfaces. In addition, by making the surface area of the non-foamed surface 4b larger than the surface area of the foamed surface 4a, more breeding water W can be discharged out of the container 1, and as a result, more breeding water outside the container 1 can be discharged. W can be taken into the container 1.

In the present embodiment, as described with reference to FIG. 1, the front end of the foam material 4 is exposed from the open end 1e and installed. According to such a configuration, a water flow is formed from the outside of the container 1 to the inside of the container 1, so that the breeding water W can be taken into the container 1 more efficiently.

A part of the bubbles B in the container 1 is treated in the breeding water W taken in the container 1 to supply oxygen. The breeding water W in which the amount of dissolved oxygen is increased is discharged out of the container 1 according to the water flow in the discharge direction, and provides a good living environment for the aquarium fish. On the other hand, the filth such as protein in the taken breeding water W is given a sufficient contact time with the bubble B in the container 1, and the filth adheres to the bubble B due to the surface active action, and the container shoulder 1c is not crushed. Extruded on the surface of the water.

A part of the bubbles B to which the filth is adhered collapses on the water surface and causes the filth to float on the water surface, but a part adheres or accompanies the filth that floats on the water surface without being crushed. It is pushed out into the inner space of the container upper part 1b. At this time, as in the present embodiment, the diameter of the container upper portion 1b is gradually reduced from the container shoulder 1c and the diameter of the container upper portion 1b is made smaller than that of the container lower portion 1a. The bubble B attached and accompanied is further pushed up to the vicinity of the discharge port 1f. The bubbles B are pushed out to the discharge port 1f in a concentrated form and discharged by the pressure in the raised container upper portion 1b.

In this way, the pressure gradually increases from the container upper part 1b toward the discharge port 1f, and the pressure is released at the discharge port 1f. Therefore, the flow of filth (contaminated water) becomes faster, and filth adheres in the discharge port 1f. It became possible to prevent that. That is, since the discharge port 1f is a narrow space having a smaller diameter than the container upper portion 1b, a high pressure is applied, and when passing through the discharge port 1f, all the bubbles B are crushed and become filth (turbid water). , Discharged to the discharge pipe 5.

Moreover, since the pressure in the space of the container upper part 1b rises due to the buoyancy of the bubbles B, the pressure promotes the concentration and discharge of dirt, enabling the extraction of dirt with low moisture and high concentration. Can be reduced.

Since the bubble B is crushed in the sealed space both in the container upper part 1b and in the discharge port 1f, the sound hardly leaks to the outside, and a silencing effect can be expected. Moreover, since the space is narrowly formed so that the pressure gradually increases from the container shoulder 1c to the discharge port 1f via the container upper part 1b, the bubbles B to which the filth is adhered do not stay. It is pushed out and it becomes difficult for dirt to adhere to the container 1. Further, since the bubbles B supplied from the foam material 4 are not supplied outside the container 1, the bubbles B do not burst in the breeding water W outside the container 1. Therefore, for example, when seawater is used, salt dripping generated by drying of bubbles that are broken and scattered on the surface of the water does not occur, which contributes to maintaining the beauty of the entire water tank T.

The polluted water pushed out from the discharge port 1f is discharged into the storage tank 6 from the discharge pipe 5 hanging down by the discharge pipe hooking portion 7g. Since the discharge pipe 5 is formed with a cut portion 5a from a predetermined position of the portion stored in the storage tank 6 to the tip, the contaminated water is guided to the tip 5b branched from the cut portion 5a, and the storage tank 6 is accumulated on the bottom surface. At this time, since the tip 5b reaches the bottom surface of the storage tank 6, it is possible to prevent the sound of dripping contaminated water from being generated.

As described with reference to FIG. 1, by providing the cut portion 5a, when the polluted water is accumulated up to the cut portion 5a, the pressure of discharging the polluted water from the discharge port 1f is pushed back by the water pressure of the polluted water, and discharged. Therefore, it is possible to prevent the contaminated water from overflowing from the storage tank 6, so that the contaminated water does not overflow from the storage tank 6 without maintenance for a long time due to absence.

Moreover, since it discharges | emits out of the container 1 from the said discharge port 1f, a large quantity of filth can be stored rather than the conventional product, without impairing the beauty | look of a water tank, and it becomes possible to reduce the work frequency of a maintenance. In the conventional product, the capacity of the cup for storing the filth installed in the upper part of the container 1 is 100 cc, whereas in the aquarium filth removal apparatus having the configuration described in FIG. 1, the storage tank 6 is externally attached. For example, even if a 1060 cc tank is installed, the aesthetic appearance is not impaired. In addition, due to the difference in capacity to store filth, in the case of the conventional product, filth must be cleaned about every 3 days. However, in the case of the present invention, since the capacity has increased dramatically, cleaning is about every 1 month. You can go to

Furthermore, by providing the storage tank 6 outside, the inner diameter of the lower body 1a of the container 1 can be about one-third or less, and the upper part 1b of the main body 1b can be about 1 or less of about 10 sentences compared to the average conventional product. I can do it now.

With the above-described configuration, the size of the cross-sectional diameter of the container lower portion 1a, the container upper portion 1b, the discharge port 1f, the length of the container lower portion 1a and the container upper portion 1b, and the diameter of the bubbles B supplied from the foam material 4 are respectively These dimensional ratios determine the functions of the aquarium waste removing apparatus according to the present invention.

For example, in an aquarium having a total water volume of 130 liters or less (so-called “small aquarium”), the average water depth is about 300 mm. Become. Therefore, the length of the container lower part 1a of the water tank waste removing device 1 according to the present invention is limited to 200 mm or less. When the length of the container lower part 1a is 200 mm, in order to perform the functions of the present invention without excess or deficiency, the inner diameter of the container lower part 1a is 28 mm, the length of the container upper part 1b is about 40 mm, and the inner diameter is 16-17 mm. The inner diameter of the discharge port 1f may be 4 mm or less.

In addition, since the quantity to which the bubble B adheres a filth increases by enlarging a total surface area, it is preferable to supply a large amount of bubbles as small as possible. For example, in the case of the septic removing device for aquarium provided in the above dimensions, the diameter of the bubbles B is preferably 0.3 to 0.5 mm.
