Description

[Detailed explanation of the idea] This invention relates to a filtration device for an ornamental fish pond.

Conventionally, filtration devices for ornamental fish ponds require a 1-sized filtration tank for a pond with a water volume of approximately 20 tons, although it depends on the size of the pond. An adsorption filtration material such as zeolite was placed on top to form a filtration tank.

However, this filtration device requires a large space, the filtration material gets dirty quickly, and cleaning and replacement of the filtration material when the filtration capacity decreases is very difficult.

In particular, when cleaning the filter media, the dirty filter media with dust attached to the top was carefully washed off with ice, and the inside of the tank was stirred to bring the debris to the surface. It was inconvenient and took too much time and effort.

Further, since dust and the like settle and adhere only to the surface side of the filter medium, the filter medium becomes clogged, and the filter medium gets dirty quickly compared to the amount of filter medium used, resulting in frequent cleaning.

This invention solves the above-mentioned drawbacks by forming a removable net filled with a filtering material, and will be described below with reference to the drawings.

FIG. 1 is a perspective view of a conventional filtration tank, in which a main pipe 1 and a number of perforated branch pipes 2 connected to the main pipe 1 are placed at the bottom of the tank. covers or surrounds the micropore network 3,
Furthermore, an adsorption filter material 4 such as zeolite is laminated thereon.

The muddy water guided through a pipe or the like passes through a filter material 4, is filtered, is introduced into a main pipe 1 through a hole in a branch pipe 2, and is drawn back from the main pipe 1 to a pond or the like.

FIG. 2 shows a filtration device A of this invention, where 5 is a filtration tank, and projections 7 for locking a filter material case 6' are provided oppositely on the inner inner wall of the filtration tank 5. Several of them are impressive.

The protrusion 7 may be a parallel plate-like protrusion as shown in FIG. 2, but it may also be a protrusion 8 with a semicircular cross section, a protrusion 9 with a concave cross section as shown in FIG. Various protruding means for locking the plate 10 and the like are conceivable.

Furthermore, the projections 7 may be continuous or intermittent.

A main pipe 12 is fixed to the bottom of the tank 5, and the main pipe 12 has holes 11 formed in the upper surface thereof in a number corresponding to the number of filter media cases 6'.

As shown in FIG. 4, the filtering material case 6' is formed into a box shape with a frame consisting of a vertical frame 18 and a horizontal frame 19 made of H-shaped timber or flat square timber. , a cylindrical tube formed of a mesh 22 containing perforated branch pipes 20, 20', 20', and a filter material 21 such as zeolite inserted so as to surround the branch pipes. Body 23, 23'
, 23'-... are installed in an appropriate number.

The end of the perforated branch pipe protrudes from the bottom mesh 22 and is connected to the case 6'.
It is connected to a connecting pipe 24 formed at the lower part of the storage pipe 25, and continues to a storage pipe 25.

Said cylindrical body 23.23', 23'' 23 nr...
- Since the end of the branch pipe is reliably connected to the connecting pipe 24, only the cylindrical body can be removed and replaced or cleaned easily.

In addition, the vertical perforated branch pipe 20°20' in the filter material case 6',
20''... By connecting the upper ends of the pipes in the same manner as the connecting pipe 24, the perforated branch pipes 20, 20' are formed.

20'-... are reinforced.

By inserting the protruding engagement pipe 25 of the filter case 6' configured as described above into the hole 11 on the main pipe 12 in the tank 5, the filter case 6' and the main pipe 12 can be easily connected together. .

A backing 26 is formed at the upper end of the hole 11, as shown in FIG. 5, to prevent muddy water from being introduced directly into the pipe from the engagement location.

In particular, during use, the motor is in operation and water is constantly being sucked, and the weight of the filter case 6' is concentrated, so that the retention is strong.

The backing 26 can have various forms as shown in FIGS. 6a"-c.

As shown in FIG. 7, in the filtration device A, muddy water containing dust introduced from a pond or the like enters from the left and right sides of the filter material case 6', and the dust is filtered by the filter material 21.
Connecting pipe 24, engagement pipe 2 from the holes of ', 20''...
5. It passes through the main pipe 12 and is returned to the pond etc.

FIG. 8 shows another embodiment in which the bottom 27 of the filtration device A' is sloped, and the main pipe 12' is formed on the sloped bottom.

This is to facilitate cleaning of the dust remaining on the bottom portion 27 and to increase the stability of the vertical installation of the filter case 6'.

The filtration device of this invention having the above structure can be made more compact than conventional filtration devices.

The filtration device requires a surface area of approximately 0.2 yards of filter material per 1 ton of water in the pond, and the larger the pond, the larger the filtration tank needed to be. A filter material case, which is installed in a container with a perforated pipe and is filled with a filter material around it, is vertically attached and detached, and the peripheral surface of the filter material case can be used to suck in water from the inside. The surface area for filtration can be increased.

For example, as shown in Figure 9, if we compare a 1rrL square filtration tank, the conventional filtration tank B can only provide a filtration capacity equivalent to 1m, but the filtration tank of this invention has a filtration capacity of 1m.
A filtration capacity equivalent to 4- of d×4 surfaces can be obtained, and it has become possible to make the filtration device 174 times larger than the conventional size.

As a result, there are more places where the filtration device can be installed, and at the same time, there is no risk of spoiling the overall beauty of the garden.

Furthermore, since the filter material case is installed vertically, dirt adhering to the surface falls downward, so the time it takes for the filter material to become dirty is longer than in the conventional case.

In addition, when cleaning conventional filtration devices, the filtration material in the filtration tank was stirred, dirty dust, etc. was brought to the surface and removed, and the tank was washed with water to clean the inside of the tank, but this was extremely difficult. It took time and effort.

On the other hand, in this invention, the filter case and cylinder containing the filter material are formed to be detachable from the filtration tank. Alternatively, the filtration capacity of the filtration tank can be returned to its initial good state by simply replacing the entire filtration tank as necessary.

The removed filter media case and cylinder can be used repeatedly by cleaning them at appropriate locations, and a centralized management system for the filter media case and cylinder can be established.

Also, as mentioned above, cleaning can be done in a very short time, just by changing the parts, so while you are doing conventional cleaning,
Compared to the case where the supply of filtered water to a pond or the like is stopped, there is no need to stop the supply of filtered water, and clean water that is constantly circulated can be supplied.

Furthermore, in the filtration device of this invention, even if a part of the filtration material case or cylindrical body is damaged, it is only necessary to replace the damaged part, making it extremely economical.

Furthermore, by forming the cylinder into a cylindrical shape, it is possible to increase the surface area that comes into contact with water, and it is possible to increase the filtration ability.

Furthermore, in the filtration device of this invention, since the filtration tank can be small as described above, it is extremely easy to install motors for suction and drainage before and after the filtration tank.
