Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a filtration device for filtering and cleaning water in ponds and aquariums.

<Problems to be Solved by the Invention> When purifying water in ponds, aquariums, etc. by filtration, a method for purifying the water by refluxing the liquid into a tank-shaped filter may be considered. However, such means are not only expensive, but also undesirable in places where it is necessary to preserve a beautiful environment, such as a garden, as they impair the aesthetic appearance. For this reason, in practice, when water becomes polluted, it is dealt with by discarding the polluted water and supplying new water. However, relying on such means has disadvantages such as leaving the water contaminated until it is time to replace it and requiring a large volume of water to replace it, which is uneconomical.

An object of the present invention is to provide a filtration device that is most suitable for filtering ponds and aquariums.

<Means for solving the problem> The upper surface has a conical shape such as a cone or pyramid, and a connecting portion having a communication port is provided at the center of the upper surface, and a planar inflow opening is further formed on the lower surface. One or more filter bodies each having an inflow opening covered with a planar filter member of the umbrella-shaped housing are vertically connected at the connecting portion, and the communication port of the uppermost housing is connected to the discharge of the pump. An inlet pipe is connected to the outlet and further connected to the inlet of the pump, with one end serving as an inlet for liquid.

<Function> The filter body is connected with the filter member exposed by vertical connection thereof, and the inside thereof is communicated with the discharge port of the pump via the communication port. Therefore, the inlet of the inflow pipe is connected to a pond.
When the device is immersed in a water tank and the pump is operated, the liquid flowing in through the inlet enters the filter body, is filtered by the filter member, flows out, and flows back into the pond and the tank. The filtrate filtered by the filter member is accumulated in the filter body, and is removed by removing the filter body as appropriate.

<Example> The configuration of an example of the filter body 1 will be described in detail with reference to FIG.

2 is an umbrella-shaped casing having a planar inflow opening 3 on the lower surface, and a threaded tube 4 serving as a connecting portion is protruded from the center of the upper surface of the cone, and the inside of the tube serves as a communication port 5. There is. The inflow opening 3 has a filter medium presser 8 formed with an annular presser piece 7 and a filter member 9.
and a support frame 10 that is screwed around the casing 2 and holds the filter member 9 on the lower surface, and a threaded frame ring 11 of the filter medium presser 8 is attached to the center of the support frame 10.
The center hole of the support frame 10 forms a threaded portion 12 into which the threaded tube 4 is screwed from below.

As the filter member 9, various planar filter members such as a planar filter paper, a filter cloth that can be stretched in a planar manner, a ceramic plate having numerous filter holes formed therein, a honeycomb structure, etc. can be applied.

Each filter body 1 is stacked in multiple stages by connecting the threaded tube 4 and the threaded part 12, and a stopper 13 is fitted into the threaded part 12 of the lowest filter body 1 to shut it off. Therefore, by connecting the threaded tube 4 and the threaded portion 12, the filter body 1
A vertical path 14 is formed in the center of the group. Further, since the upper surface of the housing 2 is conical in this connected state, the outer surface of the filter member 9 is not blocked even in the attached state.

FIG. 2 shows an embodiment of the present invention using the filter body 1 described above.

Threaded tube 4 of the uppermost filter body 1 of the filter body 1 group
The end portion of the columnar pipe 15 is screwed into the. The columnar pipe 15 is erected next to the pond x, connected to the discharge port 16 of the pump P, and its upper part is bent twice so that the end faces downward. A group of fixed filter bodies is suspended from the end above the pond x. Also, the suction port 1 of the pump P
7 is connected to an inflow pipe 19 such as a hose or steel pipe,
An inlet 20 at the other end of the inlet pipe 19, to which a check valve such as a hood valve is attached, is submerged in the pond x.

FIG. 3 shows another support means for the filter body 1, in which a connecting ring 31 is formed at the downwardly hanging tip of a support 30 erected near the side of the pond x.
The first group of filter bodies is supported by a flexible hose 30 which is screwed into the screw tube 4, and the discharge port of the pump P and the communication port 5 of the filter body 1 at the top of the first group of filter bodies are connected by a flexible hose 32. It is connected.

Next, the operation of each of the above embodiments will be explained.

When the pump P is driven, the liquid in the pond x is sucked from the inlet 20 by the pumping action, and flows into each filter body 1 from the vertical passage 14. In the connected state of the filter body 1 group, each filter member 9 is exposed downward, so that the inflowing liquid passes through the filter member 9 and flows out downward. This outflow form is shower-like and gives rise to a unique sense of taste. Further, in such a flowing state, by irradiating light with an appropriate color, it is possible to make it even more interesting.

The liquid in the pond x circulates due to the inflow from the inflow port 20 and the outflow from the filter member 9, and the liquid in the pond
The filtrate is filtered by the action of , and the filtrate is deposited in each filter body 1 . By repeating this circulation, the filter body 1
When a predetermined amount of filtrate has accumulated inside, the threaded connection between the screw tube 4 and the threaded part 12 is released, each of the filter bodies 1 is removed, the filtrate is removed, and the filter is reassembled.

FIG. 4 shows another embodiment of the present invention, in which only the pump P is located outside and the filter 1 group and the inlet 20 of the inflow pipe 19 are submerged in water. be.

This configuration is easy to carry because each of the connections constitutes one unit. For this reason,
For example, it can be applied to cleaning bath water by submerging the filter body 1 and inlet 20 in a bathtub and driving the pump P.

In each of the embodiments described above, only one filter body 1 may be used.

Further, in the embodiment, the communication port 5 is formed by making a hole in the center of the upper surface of the housing 2,
In addition, it is also possible to form a threaded tube that is screwed into the communication port 5 from the connecting frame ring 11, and to remove the threaded tube 4.

<Effects of the Invention> As described above, the present invention connects one to a plurality of filter bodies 1 each having a filter member 9 in the planar inflow opening 3, and allows the pump P to pass through each housing 2. An inflow pipe 19 is connected to the discharge port, and an inflow pipe 19 whose one end is submerged in water is connected to the inflow port of the pump P. The inflow pipe 1
(a) Since the liquid is sucked in from the inlet 20 of the filter body 1 and the liquid flows out from the filter member 9 of the filter body 1, the water in a pond, aquarium, etc. is filtered. The structure is simple and inexpensive.

(b) Unlike the system using a tank, the volume is small, and the positional relationship between the first group of filter bodies and the pump P can be set appropriately, so it is easy to adapt to the installation environment. That is, by adopting the mounting structure as shown in FIGS. 2 and 3, for example, the interest of a garden or the like can be enhanced. Moreover, by adopting the configuration as shown in FIG. 4, only the pump P can be located outside the liquid, and the atmosphere will not be spoiled.

(c) By setting the number of connected filter bodies 1, it is possible to provide a filtration device with a required processing capacity.

(d) Even if the filter member 9 is damaged, only the filter member 9 of the corresponding filter body 1 needs to be replaced. In this way, even if various failures occur, a minimum number of parts need to be replaced, and maintenance of the filtration device is easy.

(E) Since the filter member 9 is planar, various materials such as a hard filter plate can be used. Further, its shape can be selected from various shapes such as a round plate, a rectangular plate, a polygonal plate, etc. in accordance with the shape of the inflow opening 3.

It has excellent effects such as
