However, in the above-mentioned conventional purifying apparatus, since the purifying material is fixed in the purifying device and the biological water is purified by passing water from the aquarium, the purifying material is not used. However, there is a problem that it is not possible to sufficiently secure contact between the water and the aquarium water, and therefore it is not possible to obtain excellent purification efficiency.

In addition, the conventional fixed bed type is often clogged, and in this case, a sufficient purifying action cannot be performed. Therefore, it has been necessary to replace the fixed type with a new one within a relatively short period of time.

[0005] Further, it is common to determine when to replace the purifying material depending on the degree of decrease in the flow rate of the purified water discharged from the purifying device. Therefore, the storage of the initial flow rate immediately after the replacement is weakened, the comparison with the initial flow rate is not easy, and it is difficult to accurately determine the replacement time of the purifying material.

It is characterized by being made to flow inside.

Since the purifying material particles flow in accordance with the water flow in the container, the contact efficiency between the aquarium water and the purifying material particles is good, and thus sufficient purifying efficiency can be obtained. In addition, since the purifying material particles are always flowing, clogging that occurs in the conventional fixed bed method does not occur, and therefore, a constant discharge flow rate is always ensured. Further, since the flowing movement of the purifying material particles is observed from the transparent part of the purifying container, the purifying material has an interesting and excellent aesthetic effect, and has a great visual effect such that the purifying state can be visually recognized as it is.

A water outlet is provided on the peripheral wall surface of the purification vessel, and the water flow is generated by rotation of the purification vessel.

Since the water outlet is provided on the peripheral wall surface separated from the center of rotation, the discharge power of the purified water from the water outlet becomes larger, and the efficiency of replacing the water in the water tank in the purification container is improved.

On the other hand, in order to achieve the second object,

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an aquarium fish tank purifying apparatus according to an embodiment of the present invention.

FIG. 1 is a perspective view showing an ornamental fish tank purifying apparatus (1) according to the present invention.

In these figures, (2) is a purification vessel,
(3) is a purifying material particle, (4) is a rotation driving means, and (5) is a support base.

The purifying vessel (2) has two side walls (11) (1
2) and a peripheral wall (13), which are made of a transparent material. The front side wall (12) is formed integrally with the peripheral wall (13) to form a container body (2a), and the other side wall (11) is detachably joined to the peripheral wall (13) of the container body (2a). Is what is being done.

That is, as shown in FIG. 3, a hollow pivot (14) having both ends opened is erected at a central portion on the inner surface side of the side wall (12), and is provided at a central portion of the other side wall (11). Is provided with a fitting hole (11b) that can be fitted on the outer peripheral surface of the pivot (14). In addition, the peripheral wall (1
An annular ridge (11c) that can be fitted to the inner peripheral surface of 3) is provided. Further, hook-shaped locking projections (13a) (13a) are provided on the side edge of the side wall (11) of the peripheral wall (13), while one side wall (11) is provided.
Hook-shaped locking projections (11a) (11a) which can be locked to the locking projections (13a) are also provided at the outermost edge of the inner surface of the.

Thus, the joining of the container body (2a) and the side wall (11) is performed by inserting the pivot (14) of the container body into the fitting hole (11b) of the side wall (11). The inner peripheral surface of the peripheral wall (13) is fitted to the annular ridge (11c) to bring the end surface of the peripheral wall (13) into contact with the inner surface of the side wall (11), and in this state, the container body (2a) is brought into contact with the side wall (11). ), The container can be slid counterclockwise to lock the locking projection (13a) of the container body with the locking projection (11a) of the side wall. The purifying material particles (3) are exchanged by rotating the container body (2a) clockwise with respect to the side wall (11) to release the locking, and then replacing the container body (2a) with the side wall (11). Can be easily carried out by separating. The container body (2
Since a) and the side wall (11) are detachably joined, maintenance inside the purification vessel (2) can be easily performed.

On the peripheral wall (13), as shown in FIG.
Slit-shaped water outlets (15) are provided at predetermined intervals in the circumferential direction of the peripheral wall (13) in such a manner that the axial direction of the slit is parallel to the axial direction of the pivot (14). On the other hand, on the front side wall (12), a plurality of arc-shaped water inlets (16) are formed in three rows in a circular shape at the center thereof, and a plurality of water inlets (16) are formed on the outer side thereof. It is formed parallel to the direction. The diameter of the water outlet (15) and the water inlet (16) is designed to be smaller than the diameter of the purifying material particles (3) so that the purifying material particles (3) do not flow out of the purifying container (2). .

Further, a spout (15) in the peripheral wall (13)
An outwardly protruding outer rib (17) is formed at a position in the vicinity of the rotation direction, and an inward direction is also formed at a position on the peripheral wall (13) near the water discharge port (15) in the direction of rotation. A protruding inner rib (18) is formed. When the purification container (2) is rotating, the outer rib (17)
Due to the presence of the inner rib (18), a position near the outside of the water discharge port (15) behind the rotation of the outer rib (17) becomes more negative than the surroundings, and the presence of the inner rib (18) causes the water discharge port (15) in front of the rotation. Since the pressure near the inner side is higher than the surrounding pressure, the discharge of the purified water from the inside to the outside at the water discharge port (15) can be promoted. By providing such a rib, the replacement efficiency of the water tank water (W) in the purification vessel (2) can be further improved,
As a result, more excellent purification efficiency can be secured.

And, in the internal space of the purification container (2),
Purifier particles (3) are loaded. Purifying material particles (3)
Needs to flow in the purification vessel (2) by the water flow from the water intake port (16) to the water discharge port (15) generated by the rotation of the purification vessel (2). .3
It is necessary to set in the range of 0.8 to 1.2
Is preferably set in the range. The microorganisms carried on the purifying material particles (3) can decompose organic substances such as ornamental fish droppings and bait contained in the tank water to purify the tank water (W). is there.

The loading amount of the purifying particles (3) is preferably 10 to 90% by volume based on the internal volume of the purifying container (2). If it is less than 10% by volume, the purification efficiency decreases, while if it exceeds 90% by volume, the contact between the purification material particles (3) increases and the fluidity of the purification material particles (3) in the purification vessel (2) decreases. As a result, the purification efficiency is undesirably reduced. Above all, the content is more preferably 30 to 80% by volume.

The particle size of the purifying material particles (3) is usually 1 to 8 m.
m is preferably used, but is not particularly limited to this range. The shape of the purifying material particles (3) is
There is no particular limitation, and any shape such as a spherical shape, a cubic shape, and a rectangular parallelepiped shape can be used.

Further, the purification device (1) of the present embodiment includes:
Stirring promoting particles (19) having a true specific gravity of 1.4 or more are loaded in the purification vessel (2). Since the particles (19) have a large specific gravity, they are not much affected by the water flow in the purification vessel (2) and collide with the wall of the purification vessel (2) while rotating the purification vessel (2). 2) The collision with the purifying material particles (3) is repeated while moving in the interior randomly. This makes it possible to reliably prevent the purifying material particles (3) from staying in the container (2), thereby further improving the purifying efficiency.

The stirring promoting particles (19) are not particularly limited as long as the particles have a true specific gravity of 1.4 or more and are not soluble in water. Examples of the particles include ceramics, metals, hard synthetic resins, and minerals. Examples can be given. Further, the particle size of the stirring promoting particles (19) is determined by the purifying material particles (3) used.
The particle size is preferably about the same as that of the above, and usually a particle size of 1 to 10 mm is used, but is not particularly limited to this range. In addition, the shape is not particularly limited,
Any shape such as a spherical shape, a cubic shape, and a rectangular parallelepiped shape can be used.

On the other hand, the rotary driving means (4) is not particularly limited as long as it can rotate the purifying vessel (2) around its central portion.
For example, a rotary motor, an impeller made rotatable by air of aeration, an impeller made rotatable by a water flow by a submersible motor pump, or a forced jet water flow may be used. As the forced water jet, for example, a water jet is simply injected from the outside to the purification vessel to rotate the purification vessel, or a water stream is injected from the outside to the purification vessel to rotate the purification vessel. A part of the injection water flow enters the purification vessel and contributes to the water flow from the water suction port to the water discharge port, or the water flow is jetted tangentially into the vessel from the rotation axis portion of the purification vessel. Examples of the method include providing a water flow in the purification container and rotating the purification container. In the present embodiment, a rotary drive mechanism including an impeller is employed.

The rotation driving means (4) is provided with a rotor body (3
0), a rotor housing (31), and fixing pins (38).

The rotor body (30) is provided with the disk-shaped side wall (11).
And an annular partition (32) and a blade (33). This side wall (11) also constitutes one side wall of the purification vessel (2), and also serves as the side wall of both (30) and (2). As shown in FIG. 5, the annular partition (32) is annularly protruded from the outer periphery of the outer surface of the side wall (11) of the purification vessel (2) around the fitting hole (11b). 11) On the outer surface, a blade plate (33) protrudes radially so as to intersect with the partition wall (32). This blade (33)
It is composed of an outer blade plate (33a) on the outer surface side of the annular partition (32) and an inner blade plate (33b) on the inner surface side of the annular partition (32).

The rotor housing (31) comprises a housing member (34) and a bearing shaft (35). The storage member (34) has a cylindrical shape whose one end side is open, and has an inner diameter larger than that of the outer peripheral trajectory when the rotor body (30) rotates about the pivot (14) in order to store the rotor body (30). It has a slightly larger size and a width substantially equal to the width of the rotor body (30). In the peripheral wall of the storage member (34), an introduction port (34a) for introducing air is provided in a part of the lower side, and a discharge port for discharging the introduced air to a part of the upper side thereof. (34b) is provided.

The bearing shaft (35) is formed at the center of the side wall (34c) of the storage member (34) and is formed in a hollow shape having both ends opened. The outer diameter of the bearing shaft (35) is set to be slightly smaller than the inner diameter of the hollow pivot (14).

The lower portion of the rotor housing (31) is connected to a wide support (5), which will be described later, so that the rotor housing (31) is stably supported.

As shown in FIG. 7, the fixing pin (38) has a head (38b) at one end of a pin shaft (38a) and an elliptical tip (38c) at the other end. And a split groove (38d) is formed from the tip (38c) to a part of the pin shaft (38a). Pin axis (38
The outer diameter of a) is set to be slightly smaller than the inner diameter of the hollow bearing shaft (35), while the outer diameter of the enlarged diameter portion at the tip (38c) is smaller than the inner diameter of the bearing shaft (35). Is also set to be slightly larger.

In the state where the pivot (14) of the purifying vessel is inserted into the bearing shaft (35) of the rotor housing (31), the fixing pin (38) is moved from its tip (38c) to the bearing shaft (38). When inserted into the hollow part of 35), the enlarged diameter part of the tip part (38c) comes into contact with the inner wall of the hollow part, and is inserted with the groove width of the split groove (38d) of the fixing pin reduced. When the enlarged diameter portion of the portion (38c) reaches the enlarged diameter opening (35a) at the other end of the support shaft (35), it is released, and the groove width of the split groove (38d) is restored to the initial width and enlarged. The outer diameter of the diameter portion is larger than the inner diameter of the bearing shaft (35), so that the pin tip (38c) is securely held in the enlarged diameter opening (35a) without reversing, so that the purification vessel (2) ) And the rotor body (30)
In 1), it is supported without being detached in a rotatable manner.

On the other hand, if a force for pulling out the fixing pin (38) in the front direction is applied, the groove width of the split groove (38d) is reduced relatively easily, and the tip end (38c) is attached to the support shaft (35). Since the fixing pin (38) can be removed from the hollow portion through the enlarged diameter opening (35a), the purifying container (2) can be pulled out. Further, the rotor body (30) can be detached from the rotor housing (31).

The inner blades (33b) and (33b) inside the annular partition (32) in the rotor housing (31) will be described below.
The space formed between the outer blades (33a) and (33a) outside the annular bulkhead (32) is called the “inner chamber (37)”.
And the space formed between them is referred to as “outer chamber (36)”.

On the other hand, the support base (5) is formed in a substantially rectangular parallelepiped shape, and a hollow substantially rectangular parallelepiped upper cover (41) having no bottom plate connected to the rotor housing (31); A hollow substantially rectangular parallelepiped support base (42) having a height about half of that of the upper cover (41);
Are fitted to the support base (42) so that both are joined in a detachable manner.

That is, locking handles (42a) (42a) each having a locking hole are provided at the center of both side plates of the support base (42), while the center of both side plates of the upper cover (41) is provided. Locking projections (41c) (41c) which can be locked in the locking holes are formed in the portions. Then, the joining between the upper cover (41) and the support base (42) is performed by engaging the locking projection (41c) with the locking handle (42a).
It can be carried out by inserting it into the locking hole.

In the hollow portion of the support base (42), a weight member (43) having a large specific gravity is loaded so that the purification device (1) can be installed in a water tank in a more stable state. . In this embodiment, pebbles are employed as such weights (43).

Further, the upper cover (41) is a support base (42).
A support piece (44) having a support hole (44a) is provided at the edge of the upper surface of the support base (42) below the inlet (34a) of the rotor storage body (31) when fitted to the support housing (31). An air introduction passage (40) for introducing air from outside is fixedly inserted into the support hole (44a). One end of the air introduction passage (40) is opened to the outside as an air intake (40b), through which external air can be introduced by any means such as an air pump. On the other hand, a hollow cylindrical porous air stone (45) having one end opened is fitted and connected to the air discharge port (40a) at the other end, and the air stone (45) is connected to the rotor housing (31). Is positioned below the inlet (34a).

A cutout recess (41b) capable of receiving the support piece (44) is formed in the rear surface on the left side of the upper cover (41), and the upper cover (41) and the support base (42) are formed. At the time of joining, the support piece (44) and the notch recess (41b) are fitted.

In addition, in the upper half of the front surface of the upper cover (41),
Slit-shaped water intakes (41a) are provided at predetermined intervals in the longitudinal direction of the front surface such that the axial direction thereof is parallel to the vertical direction. A filtration chamber (46) communicating the water intake (41a) and the inlet (34a) is loaded with a physical filtration material (47) made of nonwoven fabric, sponge, activated carbon, gravel or the like.

Further, the side wall (34) of the rotor housing (31)
c) On the back side of the inlet, one end is connected to the filtration chamber (46) near the inlet (34a) and the other end is connected to the outside near the outlet (34b) of the rotor housing (31). An upflow channel (48) opened as an air diffusion port (48a) is arranged.

Thus, the purifying device (1) for an ornamental fish tank according to the present invention is installed on the bottom surface of the ornamental fish tank (A) as shown in FIG. 8, and the air inlet (40) of the air introduction passage (40) is provided. 40b) and one end of the air tube (B) is fitted and connected.
When air (C) is supplied through the air tube (B) by, for example, an air pump, the supplied air (C) flows through the air introduction path (40), and as shown in FIG. Through the air stone (45), it forms a fine bubble, and a part of it is introduced from the inlet (34a) through the rotor housing (3).
1) Entering the outer chamber (36), the buoyancy of the air (C) pushes up the outer blade plate (33a) to rotate the rotor body (30), and this rotation causes the rotor body (30) to rotate. The connected purification container (2) rotates in conjunction therewith. Then, the outer room (36) facing the inlet (34a)
Similarly, the air (C) is continuously introduced, so that the rotary drive of the purification vessel (2) in conjunction with the rotor body (30) is made stationary.

With the rotation of the purification vessel (2), a water flow is generated in the purification vessel (2) from the water inlet (16) to the water discharge port (15). The particles (3) will flow. Since the purifying material particles (3) flow in accordance with the water flow generated in the purifying vessel (2), the contact efficiency between the aquarium water (W) and the purifying material particles (3) is good, and therefore, sufficient living organisms are provided. Purification efficiency can be obtained. In addition, the buoyancy of the air (C) is used as a source of rotational driving force. As this power source, air for aeration for supplying oxygen to aquarium water can be used, and a new power source for rotational driving can be used. Since no source is required, running costs can be significantly reduced.

On the other hand, the remainder of the air (C) released from the air stone (45) enters the rising channel (48) as shown in FIG. 10, and flows through the rising channel (48). It rises due to its buoyancy, and the air outlet (48a) of the flow path (48)
It is released into aquarium water (W). Then, the air (C) floats in the rising flow path (48), whereby the air in FIG.
As shown in (1), an ascending water flow is generated in the flow path (48), and the aquarium water (W) is taken into the filtration chamber (46) from the intake port (41a) of the support base (5) by the ascending water flow. The taken-in tank water (W) passes through the physical filter medium (47), is physically filtered, and is returned to the tank mainly through the air vent (48a).

By providing such a rising flow path (48), the buoyancy of the air (C) can be controlled not only by the rotational drive of the purification vessel (2) but also by the intake of water into the filtration chamber (46). This is advantageous in that biological purification and physical filtration can be performed simultaneously using air for aeration.

As shown in FIG. 10, an inclined wall (39) is formed above the air stone (45) and adjacent to the inlet (34a) and inclined rearward from bottom to top. As a result, the air (C) released from the air stone (45) can smoothly enter the rising channel (48) without staying.

Further, the purifying device (1) of the present embodiment includes:
Outlets (50), (50) and an inlet (51) are provided in the right half of the side wall (34c) of the rotor housing (31) (opposite to the inlet), at a position facing the inner chamber (37). The inlet (51) is located closer to the center of the side wall (34c) than the outlet (50). A water guide channel (52) having one end connected to the inflow port (51) and the other end connected to the back surface of the filtration chamber (46) is disposed adjacent to the rising channel (48). I have.

As the rotor body (30) rotates, FIG.
As shown in (b), a water flow is generated from the inflow port (51) to the outflow port (50) through the inner chamber (37), and the water flow is filtered from the intake port (41a) of the support base (5). Since the aquarium water (W) is taken into the chamber (46), the rising channel (4)
The efficiency of water flow into the filtration chamber (46) can be improved together with the intake of water into the filtration chamber (46) by the floating of air in 8), so that the efficiency of physical filtration can be further improved. .

In the purifying device (1), the air for aeration and the water having a high oxygen content in which the air for aeration is dissolved are effectively prevented from coming into contact with the purifying material particles (3) in the purifying container (2). Therefore, not only aerobic bacteria but also anaerobic bacteria are supported in a large amount on the purifying material particles (3), and further excellent purifying performance is secured.

In the purifying apparatus (1) according to the present invention, a flowing movement of the purifying material particles (3) is observed from the transparent portion of the purifying container (2), so that the purifying apparatus is interesting and has an excellent aesthetic effect. In addition, in the purification device (1) of the present embodiment, the support base (5) is also made of a transparent material, so that it is easy to check the degree of contamination of the physical filtration material (47),
The rotation drive means (4) and the rising flow path (48) are also made of a transparent material, and the rotation behavior of the rotor body (30) and the clear flow of the air (C) are observed, so that it is more interesting. It is further improved.

In the purification by the ornamental fish tank purifying apparatus (1) according to the present invention, organic substances such as ornamental fish dung and remaining food contained in the tank water are removed by microorganisms carried on the purifying material particles (3). Since the biological purification is carried out by decomposing and purifying aquarium water, the purifying material particles (3) are not particularly limited as long as they can carry microorganisms. Examples thereof include a foam, an inorganic porous material, a porous cellulose derivative, a porous cellulose derivative coated with a compound obtained by reacting an epoxy compound and a polyamine compound, or cellulose. Among them, a porous cellulose derivative or a compound which is obtained by reacting an epoxy compound and a polyamine compound, and a material which causes a color change of the surface over time with the use of a coated porous cellulose derivative or cellulose are used. It is preferable that the user visually recognize the color change to accurately know the replacement time of the cleaning material particles.

It is not necessary to carry microorganisms on the purifying material particles (3) in advance. That is, if the purification device (1) of the present invention is installed in an ornamental fish tank, microorganisms will soon be carried on the purification material particles (3).

The porous cellulose derivative is obtained by crosslinking cellulose intramolecularly and / or intermolecularly with a compound having a functional group which reacts with a hydroxyl group of glucose constituting cellulose. By performing such cross-linking on cellulose, it is possible to reduce or prevent degradation of cellulose in a short period of time by an enzyme that degrades cellulose possessed by microorganisms, while maintaining excellent microorganism-supporting performance inherent to porous cellulose. Things.

Examples of the compound having a functional group that reacts with the hydroxyl group of glucose include a compound having an epoxy group,
N-methylol compounds, imidazolidinone compounds, compounds having an aldehyde group, acetal compounds, active vinyl compounds, aziridinyl compounds, compounds having a carboxyl group, compounds having an acyl group, compounds having an isocyanate group, quaternary ammonium compounds, Amidophosphazene compounds and the like can be mentioned. These may be reacted with cellulose alone, or may be reacted with cellulose by using two or more kinds in combination.

The compound having a functional group which reacts with the hydroxyl group of glucose is 3 to 60% by weight based on cellulose.
Is preferably reacted. If the amount is less than 3% by weight, the cellulose is insufficiently crosslinked and decomposition by microorganisms proceeds, making it difficult to use for a long period of time. On the other hand, if it exceeds 60% by weight, the excellent microorganism-supporting performance inherent to cellulose is impaired. Not preferred.

As a commercially available product of such a porous cellulose derivative, there is no particular limitation, and for example, Aquacell FZ-B (trade name, manufactured by Biomaterial Co., Ltd.) can be exemplified.

The porous cellulose derivative or cellulose is preferably coated with a compound obtained by reacting an epoxy compound with a polyamine compound, whereby an enzyme capable of degrading cellulose possessed by microorganisms and a cellulose derivative or cellulose are coated. Contact with cellulose can be avoided, and decomposition of the cellulose derivative or cellulose by these enzymes can be prevented.
Further, the positive charge of the compound obtained by reacting the epoxy compound with the polyamine compound allows a larger amount of microorganisms to be carried, and thus the purification efficiency can be further improved.

The compound obtained by reacting the epoxy compound with the polyamine compound preferably coats 10 to 60% by weight of the cellulose derivative or cellulose. When the amount is less than 10% by weight, the cellulose derivative or cellulose is decomposed by the enzyme of the microorganism. On the other hand, when the amount exceeds 60% by weight, the specific gravity of the purifying material particles increases, and the purifying material particles flow smoothly in the purifying container. Is undesirably inhibited.

The reaction ratio between the epoxy compound and the polyamine compound is 20 to 15 with respect to the epoxy compound.
It is desirable to react 0% by weight of the polyamine compound.

Examples of the polyamine compound include polyethyleneimine, polyallylamine and polyvinylamine, but are not particularly limited thereto.

Although the porous cellulose derivative is coated with a compound obtained by reacting an epoxy compound and a polyamine compound, commercially available products are not particularly limited. For example, Aquacell BZ-H
(Trade name: manufactured by Biomaterial Co., Ltd.) and the like.

In addition to the fact that the porous cellulose derivative has an excellent microorganism-carrying performance, the purification efficiency can be further improved. Therefore, the user can accurately grasp the replacement time of the cleaning material particles (3) by visually recognizing the discoloration from the transparent portion of the cleaning container.

In the purification apparatus (1) of the present invention, a porous cellulose derivative or cellulose coated with a compound obtained by reacting an epoxy compound with a polyamine compound is used as the purification material particles (3). In this case, in addition to the effect of clearly indicating the replacement time of the cleaning material particles (3), a larger amount of microorganisms can be removed by the positive charge of the compound obtained by reacting the epoxy compound with the polyamine compound. Since it becomes possible to carry on (3), the purification efficiency can be further improved.

In addition, the above-mentioned cellulose has an advantage that it can be incinerated and that it is biodegradable, so that it can be easily disposed of.
