Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to water treatment techniques, and more particularly to aeration and filtration techniques.

[0002]

2. Description of the Related Art Tropical fish and goldfish entertain viewers with brilliant color patterns and swimming shapes expressed on their bodies.
Therefore, in stores such as living spaces and restaurants, there are increasing cases of breeding various kinds of tropical fish in a relatively large aquarium in order to enhance the utility as an aqua interior.

[0003] In the case of breeding many kinds of many fish in this way, the amount of dissolved oxygen in the water in the aquarium must be adjusted according to the size and number of fish and the size of the aquarium. Eventually the fish will become starved of oxygen. Therefore, an apparatus equipped with an aeration mechanism for dissolving oxygen in water is attached to the water tank, and such an apparatus uses an aeration method in which water in the water tank is formed into water drops or a film and sprayed into the air, as shown in FIG. Things are known.

[0004] This apparatus 1 is capable of performing both aeration and filtration. The aeration performed in the device 1
Water W ₁ pumped up by the water pump 2 from the water tank 2 is sprayed from the rotating water sprinkling pipe 4 so as to be brought into contact with air in the form of water droplets or films. That is, the amount of dissolved oxygen in water is increased by giving a smaller amount of water an opportunity to come into contact with air. The water subjected to the aeration in this manner is then subjected to filtration and secondary aeration by dripping down the filtration layer 5 filled with a spherical filter medium below the water sprinkling pipe 4. The water W ₂ thus aerated in a stepwise manner is returned to the water tank 2.

[0005]

By the way, when increasing the number of fish, breeding larger fish, or replacing the tank with a larger one,
It is necessary to increase the aeration ability of the aeration apparatus 1 accordingly. For this purpose, it is necessary to make the water droplets (water amount) sprayed from the water spray pipe 4 into the air as small (small) as possible and to make contact with the air as long as possible after spraying.

One of the means is to increase the height h from the sprinkler pipe 4 to the upper end of the filtration layer 5 sufficiently to enhance the dispersion effect by the fall of the sprayed water. The whole becomes large in the height direction, and there is a problem in that space is saved. Conversely, if the height h is increased by reducing the thickness of the filtration layer 5 while keeping the height of the device 1, the function of the filtration layer 5 will be reduced. In addition, it is one method to provide a structure in which water droplets can be finely sprayed, preferably in a mist state, in the water spray hole 4a. Therefore, the amount of aerated water will also be reduced. For this reason, in particular, when used in a large water tank having a width of 1.5 to 2.0 m and a height exceeding 1 m, the aeration ability may not be able to catch up with the amount of water in the water tank. As described above, in the device 1, there is a problem that the size of the device itself is inevitably increased in order to prevent the aeration ability from being impaired and to sufficiently perform the filtration by the filtration layer 5.

In the case where it is desired to enhance the utility of the water tank 2 as an aqua interior, the apparatus 1 cannot be installed in the water tank and must be attached to the water tank.
The appearance around the aquarium also gets worse.

The present invention has been made in view of such a conventional technique, and an object of the present invention is to provide an aeration apparatus which can satisfy both requirements of high aeration capacity and miniaturization. It is in. Another object of the present invention is to provide a water treatment unit that combines this aeration device and a filtration device and contributes to space saving around a water tank.

[0009]

In order to achieve the above object, the present invention has a water inlet for taking in water in a water tank and a water outlet for discharging aerated water to the water tank side. A water pipe for an aeration apparatus for aerating water flowing through a pipe in a pipe leading to a water outlet, wherein at least an intake opening formed through a pipe wall in the pipe or a pipe is partially closed. A water pipe for an aeration device having any one of the baffles is provided.

In the flowing water pipe of the present invention in which the intake wall is formed by penetrating the pipe wall, when water flows through the flowing water pipe, the inside of the flowing water pipe has a relatively negative pressure than the outside of the flowing water pipe. Then, the air outside the tube is sucked into the tube through the intake opening in the tube wall and can be forcibly mixed with the water flowing in the tube.

Further, according to the water pipe of the present invention in which the baffle plate for partially closing the inside of the pipe is attached, the water flowing in with air from the water inlet collides with the baffle plate for partially closing the inside of the pipe. Since an opportunity to scatter and contact with the air in the pipe in a fine water droplet state is provided, a high aeration effect can be exhibited.

According to the flowing water pipe of the present invention having both of the above two features, the respective aerations can be exerted in a superimposed manner, so that the present invention is applied to an aeration apparatus used for a relatively large water tank. It is also possible to give a sufficient amount of dissolved oxygen to the water in the aquarium. In addition, since the water pipe can exhibit the excellent aeration ability as described above, the size of the aeration apparatus including the water pipe can be significantly reduced as compared with the conventional apparatus that can expect the same aeration capacity.

It is preferable that the water pipe has a plurality of pipes branched from an inlet.

According to this water pipe, the water flow from the water inlet is distributed to a plurality of branched pipes (diversion pipes). Aeration can be performed efficiently by exhibiting the aeration ability. Various types of flow pipes having such water diversion pipes are conceivable.For example, each end of a plurality of water diversion pipes branched in parallel from one water inlet is connected to the water tank side, that is, a water tank or a water tank. It may be configured as a water outlet to be connected to a filtration device attached to the device, or as a water outlet formed by concentrating the end of a water diversion pipe branched in parallel from one water inlet. According to the findings of the present inventor, a flush pipe exhibiting an excellent aeration ability due to the above-described effects is as follows.

That is, it is more preferable that the water pipe is formed in a rhombus shape which branches off from the water inlet and converges at one water outlet. In this case, if the intake opening is formed to penetrate upwardly on the upper wall surface of each of the two diversion pipes on the side adjacent to the water inlet, water does not leak out of the pipe. Further, if the baffle plate is mounted upright on the inner wall of each of the two diversion pipes on the side adjacent to the water outlet, the scattering effect due to the collision of flowing water can be enhanced.

It is preferable that the above-mentioned water pipe is formed in a relative shape such that the water inlet and the water outlet can be fitted and connected to each other.

According to this water pipe, an arbitrary number of water pipes can be connected in cascade by fitting and connecting the water inlet of one water pipe and the water outlet of the other water pipe. Therefore, even if the size of the water tank changes and the amount of water entering the water pipe changes, the aeration capacity of the aerator can be easily and easily adjusted by increasing or decreasing the number of connected water pipes. In this specification, "running water pipe" means, unless otherwise specified.
It includes not only a unit of water pipe but also a series of water pipes constituted by interconnecting a plurality of water pipes.

Further, with respect to the above-mentioned flowing water pipe,
It is preferable that the inside of the water pipe can be easily cleaned if it can be divided vertically into a plurality.

Further, the present invention provides an aeration apparatus for aerating water in a water tank, which is provided with the above-mentioned flowing water pipe. Since the above-mentioned water pipe can exhibit excellent aeration ability, according to the aeration apparatus equipped with this water pipe, it is possible to greatly reduce the size of the apparatus as compared with a conventional aeration apparatus which can expect the same aeration capacity. it can. As this aeration device, a submersion type aeration device installed in a water tank and an external type aeration device attached to a water tank can be considered. For example, the former aeration device can be configured as follows. .

That is, the submerged installation type aeration apparatus according to the present invention has a water pipe installed therein, a water intake port for supplying water in the water tank to the water pipe, and a water aerated by the water pipe flowing to the water tank side. An outer jacket member having a mouth is provided, and the outer jacket member has an air supply pipe that has one end extending above the water surface and communicating with the outside air in the accommodation room accommodating the flowing water pipe, and retaining the air in the accommodation room.

This aeration device is installed in a state where it is submerged below the surface of the water in the water tank, and functions as follows. That is, when the aeration apparatus is submerged below the water surface in the water tank, the water in the water tank flows into the flowing water pipe through the water inlet of the mantle member. Then, the pressure in the water pipe becomes relatively negative than that in the storage chamber, and the air in the storage chamber is sucked into the water pipe through the intake opening of the water pipe. At this time, since the inside of the accommodation room is communicated with the outside air by the air supply pipe, the air can stay in the accommodation room even if the air in the accommodation room is sucked into the flowing water pipe. That is, since the negative pressure state in the water pipe can always be maintained, the high aeration ability of the water pipe can be continuously exerted. The water thus aerated is drained through the drain port of the mantle member to the water tank side, that is, to the water tank or a filtration device attached to the water tank. Note that the staying state of the air in the accommodation room means that the air only needs to be in a state where air exists at least around the flowing water pipe, particularly around the intake opening in use.

On the other hand, the external aeration device can be configured as follows. That is, the external type aeration apparatus according to the present invention has a water pipe installed therein, and has an intake port for supplying water in the water tank to the water pipe and a drain port through which water aerated by the water pipe flows to the water tank side. A water supply pipe for supplying water in a water tank to the water intake port, wherein the water supply pipe is provided with an outer casing member, and the outer casing member communicates with the outside air to supply the air into the storage chamber; Has a tube.

This aeration device is installed on the side of the water tank or on the water tank, and functions as follows. That is, when the water in the water tank flows from the intake of the mantle member to the flowing water pipe through the water supply pipe, the pressure in the flowing water pipe becomes relatively more negative than that in the storage chamber, and the air in the storage chamber is formed in the flowing water pipe through the intake opening of the flowing water pipe. Is sucked into. At this time, since the inside of the accommodation room is communicated with the outside air by the air supply port, even if the air in the accommodation room is sucked into the flowing water pipe, the air can stay in the accommodation room. That is, since the negative pressure state in the water pipe can be maintained, the high aeration ability of the water pipe can be continuously exerted. The water aerated in this way is drained to the water tank side, that is, to the water tank or a filtration device attached to the water tank, through the drain port of the mantle member.

It is preferable that the above-mentioned mantle member has a water inlet adjusting member which can adjust a shielding amount of the water inlet of the water pipe.

According to this, the amount of water flowing into the water pipe can be adjusted by changing the degree of shielding of the water inlet of the water pipe. For example, when the number of connected water pipes is increased to change the aeration efficiency, Even when the amount of drainage flowing out from the drain port of the member toward the water tank changes, the amount of water input can be increased or decreased according to the amount of drainage.

It is preferable that the outer jacket member has a filter between the water inlet and the water inlet of the water pipe.

[0027] According to this, dust which may block the inside of the water pipe and lower the aeration ability can be removed in advance by the filter, so that good aeration ability can be stably and continuously exhibited. . Such a filtering tool can be constituted by a member having an opening formed so as not to impede water permeability, for example, a mesh-like member or a plate-like member having a water-passing slit. In addition to these, for example, absorbent cotton or the like, or a combination of absorbent cotton and the above-mentioned net-like or plate-like member may be used to form a filtration layer, which may be used as a filter.

[0028] The outer jacket member of the submerged aeration device includes a water receiving chamber in which water flowing out of a water outlet of a water pipe is stored below the storage chamber, and a water tank in response to a decrease in the water level in the water receiving chamber. And a pumping device for pumping water flowing out of the drainage port of the mantle member to a filtration device attached to the upper part of the water tank. According to this, the water intake device collects water in the receiving chamber. By detecting a drop in the water level, the amount of water entering the mantle member and the amount of drainage from the mantle member can be balanced.

That is, the aerated water in the water receiving layer is discharged from the drain port of the mantle member to a filtration device attached to, for example, a water tank by a water pump such as a water pump. If the drainage volume is too high and the water in the receiving reservoir is low, the pump motor will not be able to pump water and will run idle. In this case, it is necessary to temporarily turn off the power of the pump to increase the amount of water in the water receiving layer, and then turn the power of the water pump back on again. Since the water in the water tank can be taken in by detecting a drop in the water surface (water level), it is convenient to prevent the pump pump driving motor from running idle due to excessive drainage beforehand.

It is preferable that the water intake device as described above has the following configuration because it can be composed of simple mechanical elements and the operation is reliable. In other words, the water intake device is a floating member that is located on the reservoir surface in the water receiving chamber due to buoyancy and moves up and down according to a change in the water level in the water receiving chamber, and the water receiving chamber is provided on the wall surface of the mantle member and the water receiving chamber is in the open state when the water receiving chamber is in the water tank. A water intake gate that communicates with water to take in water and shuts off the flow of water into the water receiving chamber in a closed state, and a driven member that is connected to the floating member and the water intake gate and opens and closes the water intake gate according to the vertical movement of the floating member. , Is provided.

The present invention also provides a water treatment unit including the above-described aerator and a filter to which a drain port of a jacket of the aerator is fitted and connected, wherein the filter has a height. A low flat box shape, a water sampling port to which a drain port of a jacket member of the aeration apparatus is fitted and connected; a filtration chamber having a filter medium for filtering water flowing from the water sampling port; A water treatment unit having a discharge port for discharging to a water tank side.

According to this, since the aeration device is small and the filter is in the shape of a flat box having a low height, it does not occupy a large space even when installed in a water tank, or outside the water tank, for example, in a water tank. It can be installed above or below the space, and space can be saved in and around the water tank.

As the above-mentioned filter, a plurality of low-profile flat box-shaped filter boxes are connected in a row in the horizontal direction, and the plurality of filter boxes are an initial stage having the water sampling port and the filter chamber. And a final-stage filtration box having a pumping device that pumps up the water in the filtration chamber and the filtration chamber and returns the water to the water tank side through the discharge port.

That is, since each filtration box of the filtration device of the water treatment unit is formed in a flat box shape having a low height and is not connected in a stacked manner but connected side by side in the horizontal direction, the filtration device is used. The overall height can be reduced.
Therefore, even if the present water treatment unit is installed on the inner bottom of the water tank or above or below the water tank, it does not occupy a large space. In addition, since the filtration chamber of each filtration box having a flat box shape does not perform the filtration by flowing water from the top to the bottom, but has a chamber structure in which water is flowed in the horizontal direction to perform filtration, This water treatment unit can exhibit high aeration ability and high filtration ability by a plurality of filtration chambers, while achieving space saving by reducing the height.

In the above-mentioned filter, it is preferable that at least one or more middle-stage filtration boxes having the filtration chamber are connected between the first-stage filtration box and the last-stage filtration box.

According to this, since the number of the filtration boxes in the middle stage can be increased or decreased, the filtration capacity can be adjusted according to the size of the water tank, the number of aeration devices connected to the filtration box in the first stage, and the like. .

In the above-mentioned filter, a drain port of a jacket member of a submersion-installed aeration device is fitted and connected to a water sampling port, and a drain port is connected to a pumping pipe of a pumping device of another filter device which is attached to an upper part of a water tank. It is preferable to be connected and configured.

This water treatment unit performs a main filtration with a filtration device attached to the upper part of a water tank which has been widely used in homes and the like. It is used so as to perform filtration. According to this, since the main filtration is performed by the filtration device provided in the upper part of the water tank, the size of the filter directly connected to the aeration device may be small, and the water space for the migration of fish in the water tank may be increased. It can be a processing unit. Moreover, since the filter also functions as a weight for the aeration device, the aeration device can be stably installed upright in the water tank in a submerged state.

The strut 13 as the “air supply pipe” is shown in FIG.
, And three air supply holes 13a are formed in the wall surface thereof at a position located in the water pipe housing chamber 3. Further, an operation hole 13b is provided on the upper end of the support 13 slightly below (see FIG. 9). At the lower end of the column 13, the tube wall is cut out in a rectangular shape in the longitudinal direction of the column 13, and a plate-shaped end piece 13 c is inserted and fixed thereto (FIG. 7).
reference). The support 13 has such a length that the upper end can be positioned on the water surface in a state where the tip of the end piece 13c is in contact with the support 4a at the bottom of the water receiving chamber 4.

When the upper fixing plate 11, the lower fixing plate 12, and the buffer plate 14 as described above are attached to the column 13, first, water is first supplied to the mounting holes 12b of the lower fixing plate 12 that has been adhesively fixed to the column 13. The water outlet 15b of the pipe 10 is press-fitted and fitted. Then, the support insertion hole 11a of the upper fixed plate 11 may be inserted into the support 13 and the water inlet 15a of the water pipe 10 may be press-fitted into the mounting hole 11b.

The three flowing water pipes 10 shown in FIG. 1 are each formed by cascading three small flowing water pipes 10a, 10b and 10c (see FIG. 4), and the uppermost small flowing water pipe 10a is formed.
Water inlet 15a and water outlet 15 of the lowest small flow pipe 10c.
b is fitted into the mounting hole 11b of the upper fixing plate 11 and the mounting hole 12b of the lower fixing plate 12 by press-fitting, and is combined with the support 13 integrally. The water outlet 15b and the water inlet 15a of the continuous small flow pipes (10a and 10b, 10b and 10c) have a relative shape that can be fitted and connected to each other, so that the size and number of fish in the aquarium, the size of the aquarium The number of the connections can be arbitrarily set according to the degree, and the aeration ability can be easily adjusted.

Next, the small flowing water pipe 10 constituting the flowing water pipe 10 will be described.
The structure of a will be described. In addition, other small running water pipes 10
b and 10c are the same as the small flowing water pipe 10a. As shown in FIG. 4 (a), the small flow pipe 10a branches into two branches from the water inlet 15a to form two water diversion pipes 16, and the water outlet 15
It is formed in a substantially rhombic shape converging at b. By branching the conduit of the small flow pipe 10a in this way, the water to be aerated is dispersed in each of the diversion pipes 16 and the amount of water that is directly in contact with air is reduced, thus enabling effective aeration.

On the side of the water inlet 15a of the water diversion pipe line 16, a total of four intake openings 16a penetrating through the pipe wall, and from above each intake opening 16a to prevent water flowing in the pipe from scattering outside the pipe. A raised wall 16b is formed. A baffle plate 16 for partially closing the inside of the pipe is provided on the side of the water outlet 15b.
There are provided a total of four c in upper and lower stages, which are provided at right angles to the inner wall of the pipe on the flow path of the water flowing down.

As shown in FIG. 4B, the small flow pipe 10a can be divided vertically into two parts.
The convenience at the time of cleaning is considered. These are combined to form a connection ring 16d at the water inlet 15a and the water outlet 15b.
Are fitted to each other to form one small flowing water pipe 10a.

According to the small flowing water pipe 10a configured as described above, the inside of the pipe has a relatively negative pressure than the outside of the pipe due to the flow of water into the pipe. Therefore, the air staying in the water pipe housing chamber 3 through the intake opening 16a is sucked into the pipe, and the air can be forcibly mixed with the water flowing down. In addition, since the water collides with the baffle plate 16c and scatters as minute water droplets, the water can be aerated in the state of fine water droplets by further contacting the air in the pipe. Such a series of aeration is similarly performed in the other small flush pipes 10b and 10c, so that the three flush pipes 10 can exhibit high aeration ability.

When the aeration is performed by the flowing water pipe 10 as described above,
Although the air in the water pipe housing chamber 3 flows into the intake opening 16a and decreases, the water pipe housing chamber 3 communicates with the outside air through the three air supply holes 13a of the column 13 and the upper end opening (FIG. 1, FIG. 1). 3 and 8), air can be kept in the chamber of the flowing water pipe housing chamber 3, and the inside of the flowing water pipe 10 through which water flows is maintained at a relatively negative pressure compared with the inside of the flowing water pipe housing chamber 3. be able to. The lower fixing plate 12 has a circular hole 12c,
Since the semicircular hole 12d is formed (see FIG. 3C),
Bubbles generated at the same time as flowing into the water receiving chamber 4 from the water outlet 15b of the flowing water pipe 10 can be released to the flowing water pipe housing chamber 3 through the circular hole 12c and the semicircular hole 12d. Accordingly, the air can be retained in the water pipe housing chamber 3 by this, so that the negative pressure state in the water pipe 10 can be maintained.

The water receiving chamber 4 shown in FIG.
As shown by, using a floating member 17 that floats on the pool surface of the water receiving chamber 4 by buoyancy, a water intake gate 18 formed on a side wall of the water receiving chamber 4, a fishing line connecting the floating member 17 and the water intake gate 18, and the like. There is provided a "water intake device" constituted by a connecting cord 20 as a "driven member". In the water receiving chamber 4, the water in the water receiving chamber 4 is pumped up by a water pump such as a water pump Pa shown in FIG. 8 to a water tank side, in this example, a filter R attached to the water tank (see FIG. 8). A drain pipe 19 is formed as a “drain port” for supplying.

FIG. 3 shows above the floating member 17.
The buffer plate 14 shown in FIG.
7), the buffer plate 14 prevents the floating member 17 from unexpectedly moving up and down due to the water flowing down from the mounting hole 12b of the lower fixed plate 12.
That is, as shown in FIG. 5, the lower fixed plate 12 and the buffer plate 14 are positioned such that the plate surface 14c of the buffer plate 14 is located immediately below the mounting hole 12b of the lower fixed plate 12 to which the water outlet 15b of the water pipe 10 is connected. The water flowing out of the mounting hole 12b hits the plate surface 14c.

The floating member 17 is formed in a hollow cylindrical shape having an inner diameter slightly larger than the outer diameter of the support column 13. The floating member 17 receives the buoyancy and floats in accordance with the vertical movement of the pool surface of the water receiving chamber 4. ing. The intake gate 18 has a structure as shown in the rear view of FIG. 6 and the side view of FIG. 7, and the gate plate 18a to which the connecting cord 20 is fastened is pulled up and down by the vertical movement of the floating member 17 to open and close the gate. 1
8b is opened and closed. Reference numeral 18c shown in FIGS. 1 and 7 is a cap for preventing dust from entering the water receiving chamber 4, and is attached to the gate opening 18b.

The aeration apparatus 1 of the present embodiment configured as described above
Is used as follows:

First, the aeration apparatus 1 is submerged in the water tank S, and the suction cup 9 is adsorbed on the bottom surface of the water tank S. Then, the water in the water tank S is filled in the water inlet tube 5, the water pipe housing chamber 3, the water pipe 10, the water receiving chamber 4, and the strut 13 through the water inlet 6 a of the water inlet plate 6 and the drain pipe 19. In this state, the water pump Pb of the water pump Pa of the filtration device R is connected to the drain pipe 19. And
Adjustment hole 8a of water inlet adjustment plate 8 and upper fixed plate 1
The pump (Pa) is driven after the size of the water inlet (W) formed by the overlap with the mounting hole (11b) (see FIG. 9) is reduced so that the amount of water entering the aeration apparatus (1) is reduced. Then, the water in the aeration device 1 is gradually reduced to the filtration device R.
Pumped to Then, the reservoir surface P as shown in FIG.
When the water level drops to around 1, the size of the water inlet opening W is adjusted so that the amount of water entering the aeration apparatus 1 and the amount of water discharged from the water pump Pa are substantially the same. When the pool surface is stabilized at P1, the installation of the aeration apparatus 1 is completed.

Here, a method of adjusting the size of the water inlet opening W formed by the above-described adjustment hole 8a of the water inlet amount adjusting plate 8 and the mounting hole 11b of the upper fixed plate 11 overlapping each other will be described.

As shown in FIG. 9, the operation hole 13 of the support 13 is
When the operating rod 13d is inserted into the b and turned in the direction of the arrow, the support 1
3 rotates. Then, the lower fixed plate 12 adhered and fixed to the column 13, the flowing water pipe 10 mounted on the lower fixed plate 12, and the upper fixed plate 11 mounted with the flowing water pipe 10 rotate simultaneously. At this time, since the end piece 13c attached to the lower end of the column 13 is in point contact with the support 4a, the column 13 can be rotated smoothly. The rotation of the upper fixing plate 11 causes the mounting holes 11
Since the size of the water inlet opening W formed by the overlap of b with the adjusting hole 8a of the water inlet amount adjusting plate 8 changes, the water inlet amount is adjusted as follows.

That is, when the water inlet opening W is small, that is, when the amount of drainage is larger than the amount of water input, the operation rod is moved in the direction indicated by the arrow (counterclockwise) until the pool surface of the water receiving chamber 4 reaches a stable water level P1. By rotating 13d, the water inlet opening W can be enlarged. Conversely, when the water inlet opening W is too large, that is, when the amount of water entering the water receiving chamber 4 is larger than the amount of drainage from the water receiving chamber 4, the operation rod 13d is moved in the opposite direction (clockwise) as indicated by the arrow. If rotated, the water inlet opening W can be reduced. Therefore, even when the aeration apparatus 1 of the present example, which is used for a relatively small water tank, is directly diverted to a large water tank having a pumping device having a higher drainage capacity, the operator can be operated in this manner. This is convenient because it is possible to adapt the amount of water input to the amount of water discharged from the more powerful pumping device by a simple operation that does not require the hand to be wet with water.

By the operation described above, the amount of water entering the water receiving chamber 4 and the amount of drainage from the water receiving chamber 4 are balanced, and the water in the water receiving chamber 4 is stably maintained at the preferable water level P1. In this case, as shown in FIG. 7, the floating member 17 is floating at an upper position close to the buffer plate 14 by buoyancy, and therefore, the gate plate 18a connected to this by the connecting cord 20 is at the raised position. Accordingly, the gate opening 18b is closed.

When, for example, garbage is clogged in the water pipe 10 and the amount of drainage is greater than the amount of water input and the water level of the water receiving chamber 4 starts to decrease, the floating member 17 gradually descends as the water level decreases. Then, the connecting cord 20 fastened to the floating member 17 pulls the gate plate 18a downward, the gate opening 18b gradually opens, and the water in the water tank S flows into the water receiving chamber 4 and the water level recovers. . Then, as the floating member 17 rises, the gate plate 18a rises by the connecting cord 20 to gradually close the gate opening 18b, and when returning to the water level P1, the gate opening 18b is completely closed again. In this way, the water level P1 of the water receiving chamber 4 is always kept constant, so that there is no possibility that the amount of drainage from the water receiving chamber 4 becomes excessive and drops to the water level P2 where there is almost no water. Therefore, there is no need to perform the troublesome operation of rotating the pump Pa after the motor of the pumping pump Pa idles to adjust the water level of the water receiving chamber 4, and the aerated water is transferred to the water tank S. It is possible to continuously and stably reflux.

According to the aeration apparatus 1 of the present embodiment as described above,
It is possible to exhibit high aeration ability in combination with the aeration caused by the water hitting the filtration plate 7 of the water inlet tube 5 and scattering, the aeration in the above-mentioned water pipe 10, and the aeration when flowing from the water pipe 10 into the water receiving chamber 4. .

Second Embodiment: External Aeration Device (FIG. 1)
0, FIG. 11)

Next, a description will be given of an external aeration device which is used beside a water tank or is used by being attached to a filtering device attached to the upper part of the water tank. The aeration device 101 shown in FIG. 10 is a device that can be assembled to a filtration device R attached to the upper part of the water tank S. In addition, the aeration apparatus 101 of this example
In the description of the first embodiment, a description of a portion having the same configuration as that of the aeration apparatus 1 will be omitted.

FIG. 10 is an overall configuration diagram of the aeration apparatus 101.
FIG. 11 is a use state diagram of the aeration apparatus 101. The aeration apparatus 101 includes a water pipe accommodating chamber 103 and a water receiving chamber 104.
, The outer cylinder 102 is constituted by the water inlet cylinder 105,
Is detachably attached to the upper edge of the water pipe accommodating chamber 103.

The upper cover 105a of the water inlet cylinder 105 has a dome shape, and a water inlet plate 106 and a water inlet amount adjusting plate 108 are provided below the dome shape. Water entry plate 1
In 06, a water inlet and a column insertion hole similar to the water inlet plate 6 of the first embodiment are formed (not shown). Further, the water inlet adjustment plate 108 has the same adjustment holes and support insertion holes as the water inlet adjustment plate 8 of the first embodiment (not shown). Adjustment of the amount of incoming water is performed by grasping and rotating the column 113 exposed on the lower side of the water receiving chamber 104, and rotating the supporting column 113 so that the size of the inlet opening formed by the inlet of the inlet adjusting plate 108 and the mounting hole of the upper fixing plate 111 is increased. Adjust the adjustment.

The water pipe housing chamber 103 has a water inlet port 115 a in the mounting hole of the upper fixing plate 111 and a water outlet port 115 b in the mounting hole of the lower fixing plate 112.
Are provided. Further, in the water pipe housing 103, an air supply port 113a through which the outside air communicates with the pipe wall of the outer cylinder 102 is formed so as to penetrate therethrough so that air can stay in the water pipe housing 103. It is.

In the water receiving chamber 104, aerated water is supplied to the water tank side.
That is, in this example, a drain pipe 119 is formed as a “drain port” for supplying to the filtering device R installed in the water tank S. As shown in FIG. 11, the aeration apparatus 101 uses a water pump Pa of a filtration device R installed in a water tank S for supplying water to the aeration apparatus 101. Therefore, the water receiving chamber 104 is not provided with the “water intake device” as in the aeration device 1 of the first embodiment.

The column 113 has a pump pump Pa at its lower end.
And has a length such that the upper end reaches the water inlet plate 106 of the water inlet cylinder 105, and functions as a "water supply pipe". The support 113 is provided on the lower fixing plate 112.
Are adhered and fixed, and the water pipe 110 and the upper fixing plate 111 are fixed.
However, since the support 113 is used for supplying water, the first embodiment is different from the first embodiment in that there is no air supply hole 13a formed through the support 13 in the first embodiment. It is different from the strut 13 in the form.

When assembling the aeration apparatus 101,
First, the water pipe 110 is attached to the lower fixing plate 112, and then the upper fixing plate 111 is attached, and this is inserted from above the water pipe accommodating chamber 103. Then, in this state, if the water inlet tube 105 is mounted on the upper end of the water pipe housing chamber 103, the aeration apparatus 101 shown in FIG. 10 is obtained.

Next, a method of using the aeration apparatus 101 will be described. The aeration apparatus 101 includes a downward “U” -shaped leg F so as to be integrally attached to the filtration apparatus R. The water in the water tank S pumped up by the water pump Pa of the filtration device R is supplied to the upper side of the water inlet plate 106 through the water suction pipe Pb and the strut 113 connected thereto, and through the water inlet and the water inlet of the water inlet amount adjustment plate 108. Running water pipe 11
0 is supplied. Then, the water aerated in the flowing water pipe 110 is supplied from the water receiving chamber 104 to the filtration device R through the drain pipe 119, and then filtered and returned to the water tank S.

The aeration devices 1 and 10 according to each of the above embodiments
1 can be implemented by changing the design. First,
Although the aeration devices 1 and 101 of the first and second embodiments have a configuration in which three water pipes 10 and 110 are provided, the number of mounting holes in the upper fixed plate and the lower fixed plate to which the water pipes are mounted, and If the size of the outer cylinder or the size of the small flowing water pipe is changed, the number and size of the flowing water pipes, or the arrangement thereof, can be implemented in any mode.

Further, a separate shape may be adopted for the flowing water pipe and the outer cylinder. For example, even if all the small flowing water pipes are not provided with the intake opening or the baffle plate, the intake of some small flowing water pipes is not performed. An aperture may be provided, and a baffle may be provided for other small flow pipes. Of the three water pipes, one of the water pipes has only an intake opening, the other has only a baffle plate, and the remaining flow pipe has an intake hole and a baffle plate. May be provided.

Further, the three water pipes 10 and 110 in each of the above embodiments may be formed, for example, in a helical shape surrounding the column and appropriately provided with a baffle plate or the like. Alternatively, a running water pipe may be formed in a spiral staircase surrounding the column, and the stepped portion may function as a baffle plate to perform aeration.

Further, in each of the above embodiments, the outer cylinders 2 and 102 having a specific length are shown, but the running water pipe accommodating chamber of the outer cylinder is formed by the inner cylinder and the outer cylinder, and the support column is also the same. If it is formed so that it can slide in the length direction as a whole, the length of the flowing water pipe can be changed by increasing or decreasing the number of connected small flowing water pipes, and the aeration capacity according to the size of the water tank and the number of fish etc. It can be adjusted easily and freely. In addition to this, for example, the upper part of the upper fixing plate can be detached, and another aeration device formed only by the water pipe housing chamber is prepared so that it can be connected to the upper fixing plate. Good.

The filter plate 7 shown in the above embodiment is formed with a water passage slit. However, for example, a plate having a mesh or the net itself may be used. Alternatively, the filter plate 7 may be used instead of or instead of the filter plate 7. In addition, a filter tool made of absorbent cotton or the like may be attached.

In the aeration apparatus 1 of the first embodiment, the water inlet tube 5 is a separate member that can be fitted to and removed from the upper edge of the water pipe housing chamber 3. The chamber may be integrally formed of a tube material. In this case,
For example, the buffer plate and the lower fixing plate are fixed to the column, the upper fixing plate, the water inlet adjustment plate, and the filtration plate are formed so that the inner diameters become smaller in order, and the supporting column has a step corresponding to the inner diameter of these plates. What is necessary is just to provide a part and fix each plate by locking at the said step part. Note that the same modification can be made in the aeration apparatus of the second embodiment.

In the second embodiment, the external type aeration device 101 is shown which is attached to the filtration device R above the water tank. However, only the aeration device is attached to the side of the water tank, or the aeration device and the filtration device are connected to the water tank. It is also possible to carry out the modification so as to be installed beside the.

The aerators 1 and 101 according to the first and second embodiments can be partially omitted. For example, with respect to the aeration apparatus 1 of the first embodiment, if the amount of water entering the water receiving chamber 4 is adjusted by adjusting the amount of water entering the water receiving chamber 4 to balance the amount of drainage, the aeration apparatus without the "water intake device" is provided. It is also possible to implement as. Further, the aeration apparatus 101 of the second embodiment also includes, for example, the amount of water entering the water pipe 110 and the water pipe 11.
If the drainage from zero is almost the same,
The present invention can be implemented in a mode that does not include the water input amount adjustment plate 108.

FIG. 13 shows an aeration apparatus 201 of this embodiment. The effect of the aeration apparatus 201 of this example is the same for the parts having the same structure as the aeration apparatus 1 of the first embodiment. The difference lies in that the bottom shape of the outer cylinder 202 and the drainage pipe 19 and the "water intake device" like the aeration device 1 of the first embodiment are not provided. That is, the filtration device 3 is provided at the bottom of the outer cylinder 202.

Upper lids 311, 32 screwed to 0, 320, 330
FIG. 15 is a plan view showing a state where 1, 331 and the like are removed.

The corner 313d of the first-stage filtration box 310
1 is provided at the corner 323b of the middle filtration box 320.
As shown in FIG. 6 (a), the joint 340 is fitted. Similarly, the joint 340 is fitted into the corner 313c of the first-stage filtration box 310 and the corner 323a of the middle-stage filtration box 320. As a result, the first-stage filtration box 310 and the middle-stage filtration box 320 are interconnected. The middle filtration box 320 and the final filtration box 330 are connected to each other by fitting the joint 340 in the same manner.

Further, corner 3 of first-stage filtration box 310
As shown in FIG. 16 (b), a corner part 341 is provided at the corner 333d of the filtration box 330 at the end of the filter box 330 at the end of the first stage and at the corner 333c of the filtration box 330 at the end of the stage. As shown in FIG. 16 (c), corner parts 342 are respectively attached.

15 and the water inlet pipe 325a of the middle filtration box 320
The water pipes 325 of the middle filtration box 320
As shown in FIG. 17, b and the water inlet pipes 335 of the final filtration box 330 are connected by a joint pipe 343.

Next, the processing performed by the filtering device 300 of this embodiment along the flow of water will be described with reference to FIG. Sampling port 31 formed in top cover 311 of first-stage filtration box 310
The water that has flowed down from 2 flows from a watering column 316 having a watering slit 316a as shown in FIG. This filter medium 302 is barley stone that can dissolve minerals in water. Then, the water flows through a slit plate 319 having a plurality of vertical slits and a water outlet pipe 315, and then flows into a filtration chamber 327a through a water inlet pipe 325a of a middle filtration box 320.

The middle filtration box 320 is divided into two filtration chambers 327a, 327b by a partition wall 328 in the longitudinal direction.
Is divided into This division is made for the following reason. That is, if the partition wall 328 is not provided, water flows between the water inlet pipe 325a and the water discharge pipe 325b, but water stops in a room separated from the water inlet pipe 325a and the water remains in the filtration chamber. . On the other hand, when the partition wall 328 is provided as in the present embodiment, water flows in the longitudinal direction of the filtration chambers 327a and 327b, so that water does not remain in the filtration chambers 327a and 327b and flows one after another. The incoming new water can be filtered. Thus, the middle filtration box 320
Flows into the two filtration chambers 327a and 327b in which the filter medium 302 is spread, flows through the water discharge pipe 325b, and flows into the water inlet pipe 335 of the filtration box 330 at the last stage.

Water inlet pipe 3 of final filtration box 330
An opening 335a formed by cutting out a vertically long V-shape along the longitudinal direction of the pipe is provided in 35 at a downward direction. This is because the flow of water at the V-shaped sharp end where the opening width of the opening 335a is small has a momentum, so that the water flows out slightly less, and the flow of the water becomes gentler as the distance from the water inlet side of the water inlet pipe 335 increases. Therefore, the width of the V-shaped opening is increased to increase the amount of water flowing out from the opening 335a, and a uniform flow of water flowing in the longitudinal direction of the filtration chamber 337 is created over the entire area in the width direction of the filtration chamber 337. Filtration room 337
This is because there is no portion where water remains. The water flowing out of the water inlet pipe 335 is filtered through a slit plate 339a having a plurality of vertical slits and filtered in a filtration chamber 337 in which the filter medium 302 is spread, and then passes through the slit plate 339b again to be discharged from the submersible motor 350 for drainage. After being pumped, the top cover 3 of the final filtration box 330
Outlet 350a of underwater motor 350 extending upward from
And a discharge pipe 352 connected to the discharge port 350a.
Through the water tank S.

The water treatment unit 400 of the present embodiment as described above
According to this, by increasing or decreasing the number of the filtration boxes in the middle stage according to the size of the water tank, the filter box can be installed and used in the water tank, and the space around the water tank can be saved. In addition, since each filter box is connected in a flat box shape having a low height and connected side by side, the height of the filter device can be reduced. Therefore, it can be installed on the inner bottom of the water tank or below the water tank, and the space around the water tank can be reduced. Further, since the filtration chambers 310, 320, and 330 have a structure in which water is not supplied from top to bottom to perform filtration but water is supplied in a horizontal direction to perform filtration, the water treatment unit 400 is used. Has a high aeration capacity and a plurality of filtration chambers 310, 320,
High filtering ability can be exhibited by combining with 330.

[0098] The water treatment unit 400 of the third embodiment.
Can be implemented with design changes. Aeration device 2
01 can be implemented with the same design change as described in the first embodiment and the second embodiment. Further, when the filtering device 300 is exemplified,
The filtering device 300 includes the middle filtration box 320. However, when the size of the water tank is small, the first filtration box 310 and the last filtration box 3 are not used.
It is possible to connect and use only 30 or, when the size of the water tank is large, further connect and use a plurality of middle filtration boxes.

Although the filtering device 300 of the above embodiment is arranged in a water tank, the filtering device is installed below the water tank, and the aeration device is installed in a through hole provided in the inner bottom of the water tank. You may make it connect to the water sampling port of a filtration apparatus, and use it in the state penetrated.

Fourth Embodiment: Water Treatment Unit (FIG. 18)

The water treatment unit 600 of this example is configured by combining the aeration device 201 of the third embodiment and a filter 500. A water sampling port 510 that is fitted and connected to the drain port 202a of the aeration apparatus 201 is formed in the filter 500 in the same manner as in the third embodiment. Also, this filter 500
The outlet 520 formed in the flexible tube 5
The water which is connected to the water pumping pipe Pb of the filtration device R attached to the upper part of the water tank S via the water filter 30 and is additionally filtered in the filtration chamber (not shown) of the filter 500 is pumped up by the water pump Pa. The main filtration is performed by the filtration device R.

The filtration chamber has a two-stage upper and lower chamber structure with a partition plate having water holes. The upper chamber is filled with a filter medium, and the lower chamber is provided with a discharge port 520. The filter 500 as a whole has such a weight that the upright posture of the aeration apparatus 201 can be stably maintained in a submerged state, and also functions as a weight.

According to the water treatment unit 600 of this embodiment, the main filtration process is performed by the filtration device R above the water tank S, so that the size of the filtration device 500 connected to the aeration device 201 can be compared. It is possible to provide a compact water treatment unit in which the size of the water treatment unit can be reduced and the space for the migration of fish in the water tank S can be increased.

Although the filter 500 of this embodiment is merely a rectangular one as an example of the “low-height flat box shape”, if the appearance is simulated by a rock or a tree, for example, A natural scene can be created in the aquarium, and the utility as an aqua interior can be enhanced.

[0105]

As described above, according to the aeration apparatus of the present invention, a single aeration apparatus can exhibit high aeration ability,
Moreover, the aeration capacity can be easily adjusted by increasing or decreasing the number of intake openings and baffles provided in the water pipe, and the number of the water pipe itself, so that it can be used from small water tanks placed in home living space to large water tanks for business use. It has high versatility and is advantageous in terms of cost even when the aeration capacity is expanded.

According to the aeration device of the type installed in the water tank, the space around the water tank can be reduced. Furthermore, according to the external type aeration device, if a plurality of aeration devices are installed in parallel without being limited to the space in the water tank, the length and width of the device exceed 2 m as in a commercial water tank. It can also be applied to large water tanks.

When the shape of the water pipe is a rhombus or the like, it is possible to enjoy the aesthetic appeal and the utility as an aqua interior is high.

Further, according to the water treatment unit of the present invention in which the aeration device is connected to the flat box-shaped filtration device, the height of the filtration device can be reduced. Therefore, the filtration device can be installed on the inner bottom of the water tank or below the water tank. The space around the water tank can also be saved. Moreover, since the filtration chamber of each filtration box having a flat box shape does not carry out filtration by flowing water from top to bottom, it has a chamber structure in which water is supplied in a horizontal direction to carry out filtration. A water treatment unit that exhibits high aeration capacity and high filtration capacity by a plurality of filtration chambers while achieving space saving by reducing the height can be achieved.

Further, according to the water treatment unit of the present invention in which the submersion type aeration device is connected to the filter, the main filtration process is performed by the filtration device at the upper part of the water tank, so that the device is connected to the aeration device. The size of the filter can be small, and a compact water treatment unit that can take up a large space in the water tank can be provided. Moreover, since the filter can also function as a weight, the upright posture of the aeration apparatus can be stably maintained.
