[Description of the Prior Art] As filtration devices, open gravity type, closed forced type, and open forced type (Japanese Patent Application Laid-Open No. 1983-91150) are used, but they are not suitable for large storage tanks such as ponds and water tanks. In the case of filtering the water to be treated inside the tank, in either method, a filtration device separate from the storage tank is installed near the storage tank.
Water to be treated is introduced from the pond to the filtration device for filtration.

[Problems to be Solved by the Invention] In the prior art, the storage tank and the filtration device are generally configured separately, which makes the filtration device expensive and the water to be treated in the storage tank is There was a problem that it was not purified evenly.

The present invention relates to a filtration device that solves the problems of the prior art by disposing a frame-like plate body having a strainer over the entire bottom surface of a storage tank above the bottom surface. However, in order to lay a large number of plate bodies all over the bottom surface of the potato storage tank, a means for easily and firmly connecting the plate bodies is required, and such a connecting means has not been thought of.

In addition, the plate body is 1, for example, 30c equipped with a strainer.
The plate body is made up of a frame with 30 c layers, and a load of 0.6 kg/cin'' is applied to the plate body where the strainer is clogged, and a force of 540 kg acts on the entire plate body. It is necessary to reinforce the center of the bottom.

[Object of the Invention] The present invention was invented based on the above-mentioned request, and it is possible to easily connect adjacent plates of a plurality of plate bodies disposed above the bottom surface in a storage tank, and to connect each plate body. To provide a filtration device in which a plate body having a strainer can be spread over the entire bottom surface of a storage tank with the top surface of the filtration device being horizontal.

[Means for Solving the Problems] In order to achieve the above object, the present invention forms legs projecting toward the bottom surface of the storage tank on the outer edges of adjacent plate bodies, and A plurality of plate bodies are connected by inserting them into one pipe-shaped support member. The length of each support member is cut to an appropriate size depending on the depth of the bottom surface of the storage tank.

[Function] Plate bodies can be connected by inserting the legs of the outer edges of adjacent plate bodies into the same pipe-shaped support member, and a large number of plate bodies can be integrated into an integral structure, so that the bottom surface of the storage tank can be connected. Can cover the entire surface. Then, by cutting the length of the pipe-shaped support member to a size corresponding to the depth of each bottom surface, the top surface of the plate body can be made on the same horizontal plane.

[Example] Next, an example of the present invention will be described based on the drawings. A plate body 1 used in this example is formed from a square frame as shown in FIG. 1, and has vertical and horizontal ribs 2. It is also reinforced by ribs 3 and diagonal ribs 4. Further, a mesh strainer 5 is provided on the front side (opposite side in FIG. 1) as shown in FIG. 2.

Here, a large number of plate bodies 1 are placed adjacent to each other on the bottom side of a storage tank in a wide area such as a pond or water tank in which water to be treated is stored, and are laid so as to cover the bottom surface. Note that an appropriate gap is formed between the plate body l and the bottom surface. Also plate 1
Filter media are stacked on the upper surface of the body, and the water to be treated is sucked into the gap via the filter media and the strainer 5 of the plate body 1 by the suction force of the pump that engages in the gap, purified, and discharged from the tank. Ru.

As shown in FIGS. 1 and 2, on the back side of the plate body 1, the four corners of the outer edge 6 protrude toward the bottom side of the storage tank (in FIG. 1, they are projected upwards). ing)
Legs 7a each having a hollow cylindrical shape divided into four equal parts in the vertical direction are integrally formed. In the middle of the four corners of the outer edge part 6, there is a leg 7 in the shape of a hollow cylinder divided into two in the vertical direction.
b is integrally formed. Further, on the lower surface inside the outer edge portion 6 of the plate body 1, hollow cylindrical legs 8 are formed which similarly protrude toward the bottom surface side. Specifically, the leg 8 is provided at the intersection point of the vertical and horizontal ribs 2 and 3 (including the center intersection point of the plate body 1).

As shown in FIG. 2, a spherical strainer 9 is inserted into the upper surface of the plate body l of this embodiment.

The spherical strainer 9 increases the effective area of the strainer, smoothes the flow of the water to be treated, and improves the filtration rate. In this embodiment, the spherical strainer 9
is provided at the position where the leg 8 is disposed, so the spherical strainer 9 is inserted into the hollow cylindrical through hole IO of the leg 8. Of course, the legs 7a, 7b, and 8 are integrally formed when the plate body l is formed. Further, the outer diameters of the hollow cylindrical tubes of the legs 7, 7b, and 8 are formed to have the same diameter.

FIG. 2 shows a state in which four plate bodies l are arranged with their outer I& portions 6 in contact with each other, and the legs 7a provided at the four corners of each outer edge portion 6 are divided into four equal parts. The four legs 7a make up one cylindrical shape, that is, the same shape as the leg 8. Although not shown in the figure, the legs 7b provided in the middle of the four corners of the outer edge 6 of the two plate bodies 1 touch each other at a vertical cut plane that is divided into two halves, and the two legs 7b form one piece. Cylindrical shape, i.e. leg 8
It has the same shape as .

Here, when installing the plate body l in a pond etc., the third
As shown in the figure, the pipe-shaped support member 11 is attached to the leg 7a.
and into leg 7b and each leg 8.

At this time, since the square plate bodies 1 are placed adjacent to each other, the four legs 7a and the legs 7b of the two bonds are integrally joined by the support member 11 of the one bond. Further, each support member 11 is inserted into each leg 8. The length of each support member 11 is cut to a length that allows its lower end surface to come into contact with the bottom surface of the storage tank. Here, if the bottom surface of a pond or the like is inclined at an inclination angle of 0 as shown in FIG. 4, the support member 11 is
An inclined surface 15 having an angle of θ is formed at one end. That is, the length and angle θ of the axis of the support member 11 differ depending on the location of the pond or the like. In FIG. 4, each plate body 1 is supported on a bottom surface 14 by a support member 11, and the inclination angle of the inclined surface 15 of the support member 11 is set so that the upper surface thereof is held horizontally.

The support member 11 is formed by cutting an existing pipe-shaped member into a suitable axial length, and can be manufactured relatively easily. Therefore, compared to the case where the legs 7a, 7b, and legs 8 of the plate body l are dimensioned to be in direct contact with the bottom surface 14, it can be carried out much more easily, and the plate body! The legs 7a and 7b of each plate body l are fixed by the support member 11 as described above, which can be easily adapted to the case where it is necessary to change the dimension of the gap 16 between the plate body l and the bottom face 14. As a result, each plate body 1 can be reliably connected.

Further, by connecting the support member 11 supported by the bottom surface 14 to the legs 8 in the center of the plate body 1, the load applied on the plate body 1 can be sufficiently withstood.

[Effects of the Invention] As described above, according to the filtration device according to the present invention, it is possible to connect a large number of plate bodies without gaps and cover the entire bottom surface of the storage tank.

In addition, since the plate body is supported by a support member made of existing pipes, even if the depth of the bottom of a pond or the like is complicated,
The upper surface of the plate body can be easily leveled.

Furthermore, since the central portion of the plate body can be supported by the support member, it can be applied to locations with high water pressure.
