Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a pond water filtering device, and more particularly to a filtering device having low power consumption and improved filtering efficiency.

[Prior Art] Conventionally, as a filtering device for pond water, the pond water is filtered by the filtration tank by raising a pumping pipe having a spout from a filtration tank installed in the pond and pumping it with a pump. There are a submersible type filtering device that discharges this filtered water into a pond from a spout, and a land type filtering device that installs a filtration tank on land and pumps the pond water with a suction pump to circulate and filter.

There are an axial flow type, a mixed flow type, and a spiral type as an impeller structure of a general pumping pump used in the above-mentioned pond water filtering device, but each has the following advantages and disadvantages.

The axial flow type has the lowest power consumption (about 1/1 of the spiral type)
10) A large amount of water can be pumped, but the pumping head is the lowest of the above three types.

The diagonal flow type can pump a large amount of water with a low head, but consumes more power (about twice) than the axial flow type, and the head is higher than the axial flow type. In this sense, it has intermediate characteristics of axial flow type and spiral type.

The spiral type can pump water of a medium capacity in the medium head, but it consumes more power than the axial flow type and the diagonal flow type, and the electricity charge is high and the pumping amount is small.

Conventionally, as the above-mentioned submersible filtration device, a motor is arranged at the upper end of the pumping pipe that has been raised from the filtration tank to be installed in the pond water, and the main shaft that penetrates the pumping pipe is located inside the filtration tank. A rotary impeller is often used, but an axial flow type pumping pump is used in this type of submersible filter apparatus.

Further, most of the general circulation pumps used in land-based filtration devices and the like are of the spiral type.

[Problems to be Solved by the Invention] As described above, the submersible filtration device of the type in which the motor is arranged at the upper end of the pumping pipe can circulate and filter a large volume of water at a low electricity rate, and thus pond water filtration is possible. Although it is widely used as a device, it has a drawback in that the size of the filtration tank cannot be increased in terms of price and space in the pond.

On the other hand, in the case of a land-based filtration device, there is no restriction on the space inside the pond, and although the filtration tank can be made any size, the price is several times that of an underwater filtration device. The whole becomes expensive. In addition, in this kind of pond water filtration device that should be operated at all times, the electricity charge is a very important factor, but the above-mentioned land-based filtration device has a drawback that it consumes a large amount of electricity and the electricity charge is large. .

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks,
The advantages of conventional submersible filtration device of the above type such as power consumption can be utilized as it is, the filtration capacity can be increased without increasing the power consumption, and the habitat space for fish in the pond can be reduced. An object of the present invention is to provide a pond water filtering device that does not cause fear.

[Means for Solving the Problems] A pond water filtering device according to the present invention is installed in pond water, and a pumping pipe having a discharge port is erected in a filtration tank filled with a filter medium inside and is pumped by a pumping pump. The main filtering device of the submersible type that discharges filtered water from the spouting port projecting on the upper part of the pumping pipe by the above, and has a water supply port and a spouting port and is filled with a filter medium inside, It is configured by an auxiliary filtration tank installed near the water surface and a connecting pipe that connects the water outlet of the main filtration device and the water supply port of the auxiliary filtration tank.

In this case, the auxiliary filtration tank can be installed in the vicinity of the main filtration device so that at least a part thereof is located in the pond water. For example, the auxiliary filtration tank is provided between the filtration tank and the water outlet in the main filtration device. It may be arranged or installed on a foot stand so that at least a part of it is located in the pond water on the side of the main filtration device.

Alternatively, the auxiliary filtration tank may be installed on land and the filtered water may be aerated to the pond from the outlet of the auxiliary filtration tank.

[Operation] The main filtration device is installed in water in the same manner as in the past, and the pond water is filtered by the filtration tank whose inside is filled with the filter material by pumping with the pump, and the filtered water is spouted from the spout. When the water supply port of the auxiliary filtration tank and the water supply port of the auxiliary filtration tank are connected by a connecting pipe, the water discharged from the water discharge port reaches the auxiliary filtration tank, where it is further filtered by the filter material inside and is returned to the pond. For this reason, the conventional pumping pump of the main filtration device can improve the filtration efficiency, so that the power consumption does not increase.

In this case, the number of times the filter material is washed can be significantly reduced by changing the materials of the filter material of the filter tank and the filter material of the auxiliary filter tank in the main filtration device.

Generally, the habitat of fish is near the bottom of the pond or near the middle of the water, but since the auxiliary filtration tank is installed near the surface of the water, there is no risk of narrowing this habitat space.

In addition, the main filtration device usually has a large distance between the filtration tank installed at the bottom of the pond and the spout that laterally protrudes above the water surface, and this part is not a fish habitat but a dead space. However, if the auxiliary filtration tank is installed in this part, the dead space can be effectively utilized to the maximum.

[Embodiment] An embodiment of the pond water filtering device according to the present invention will be described with reference to the drawings.

In the figure, 1 is a main filtration device installed in a pond, and a conventional submersible filtration device can be used,
In a filter tank 2 which is filled with a filter medium and installed at the bottom of a pond, a pumping pipe 3 with a water discharge port 4 protruding laterally is provided at the top and pumping is performed by a pumping pump (not shown). Thus, the filtered water is discharged into the pond from the water discharge port 4.

Reference numeral 5 denotes a drive source arrangement portion installed on the upper portion of the pumping pipe 3, which has a built-in motor and drives a drive shaft arranged in the pumping pipe 3 to drive the impeller at the tip of the drive shaft. It is designed to pump water. Further, the drive source arrangement portion 5 is generally formed in a garden light shape, and an illumination light source such as a fluorescent lamp is generally arranged inside.

When the auxiliary filtration tank 6 is thus installed between the filtration tank 2 and the water outlet 4, the filtration tank 2 installed at the bottom of the pond and the water outlet 4 protruding laterally above the water surface. It is possible to effectively use the dead space between them, and as described above, if the notch 10 of the mold is provided in the "U" of the auxiliary filtration tank 6 and the pumping pipe 3 is fitted into this, the washing can be performed. At the time of removing the auxiliary filtration tank 6 for replacement, the auxiliary filtration tank 6 can be easily separated by pulling out the auxiliary filtration tank 6 in the lateral direction.

In the embodiment shown in FIG. 3, the auxiliary filtration tank 6 is provided with a foot 11 so that the auxiliary filtration tank 6 is installed on the side of the main filtration device 1, which is a fish habitat. The space below the filtration tank 6 is secured.

In the embodiment shown in FIG. 4, the auxiliary filtration tank 6 is installed on land. In this case, the filtered water is aerated from the discharge port 8 of the auxiliary filtration tank 6 and returned to the pond to return oxygen to the pond water. Can be replenished.

[Advantages of the Invention] According to the pond water filtering device of the present invention, the pond water can be filtered only by the conventional submersible main filtering device, and of course, the outlet of the main filtering device and the auxiliary filtration tank can be filtered. By connecting the water supply port with the connecting pipe, the pumping capacity of the pumping pump in the main filtering device can be used as it is to increase the filtering capacity without increasing the electricity charge.

Further, by changing the material of the filter material of the filter tank and the filter material of the auxiliary filter tank in the main filtering device, the number of times the filter material is washed can be significantly reduced, and the filtration efficiency can be increased, and of course, the auxiliary filter tank Since it is installed near the surface of the water, there is no fear of narrowing the habitat space for fish, and it is ideal for this type of pond water filtration device.
