2. Description of the Related Art Conventionally, a septic tank 10 of this purifying apparatus is composed of a cylinder 3 between an upper flange 1 and a lower flange 11 shown in FIGS. 5 and 6, and a diffusion plate 2 is provided inside an inlet 14 and below the diffusion plate 2. A cylindrical aluminum anode 5 concentrically opposed to a cathode 4 and a cathode 4
Is provided and is fixed to the upper flange 1. The upper agglomeration portion is held between the aggregating portion that generates the aggregating material by applying the aggregating voltage between the aluminum anode 5 and the cathode 4 and the filtering portion that is filled with the filter material 8 having a certain particle size distribution to keep dirty water and agglomerate. A circular holding plate 6 having a large number of water passage holes 12 through which the material passes and fastening holes 13 is provided, and is fixed to the cathode 4 with fastening materials such as screws 7.

However, in the septic tank of the above-mentioned conventional purifying device, the dirty water that has entered from the inlet 14 changes its flow in the outer peripheral direction by the diffusion plate 2 and hits the inner surface of the cylinder 3 to reach the inner surface of the cylinder 3 and the cathode. 4, passes through the surface of the anode 5, passes through the hole 12 of the holding plate 6, and flows out from the filtration section to the outlet 15. Since the cathode 4 and the anode 5 have the same height and are lower than the diffusion plate 2, dirty water flows between the cylinder 3 and the cathode 4 and the anode 5 and the cathode 4
Since it is difficult to flow between the electrodes, the aggregating material such as aluminum hydroxide generated when applied between the electrodes is likely to be accumulated between the electrodes, and when solidified, the aggregating material does not flow on the surface of the filtration part, which reduces the purification performance. Had challenges.

Further, if the space between the electrodes is blocked by the aggregating material, the cleaning liquid does not pass during cleaning of the septic tank 10, so that the cleaning becomes insufficient and the purifying ability is not restored.

The present invention solves the above-mentioned conventional problems, and an object thereof is to effectively purify and improve durability.

[0006]

In order to solve the above-mentioned conventional problems, in the purifying apparatus of the present invention, the upper end of the cathode concentrically opposed to the cylindrical aluminum anode in the septic tank is higher than the aluminum anode. It is provided near the flange.

As a result, the dirty water entering from the inlet is
The diffusion plate changes the flow in the outer peripheral direction, hits the upper end of the cathode closer to the upper flange than the anode, passes between the cathode and the anode,
Since it flows out from the filtration part to the outlet through the notch of the holding plate, agglomerate such as aluminum hydroxide generated by applying between the electrodes does not accumulate between the electrodes or block the electrodes, and the filtration part surface Because it flows into the water, effective purification can be obtained for a long period of time.

[0008]

Constituting from the lower filter part, the aggregating material such as aluminum hydroxide generated by applying between the electrodes flows to the surface of the lower filter part due to the dirty water flowing between the electrodes, so that effective purification can be achieved for a long time. To be

According to the second aspect of the present invention, in particular, the upper end of the cathode concentrically opposed to each other is provided at the height between the diffusion plate and the upper flange, so that the dirty water entering from the inlet is directed to the outer peripheral direction by the diffusion plate. Most of the dirty water hits the upper end of the cathode near the flange above the diffuser plate, and the aggregating material such as aluminum hydroxide generated by applying between the electrodes flows between the electrodes, causing the dirty water to flow between the electrodes. As it flows to the surface, effective purification can be obtained for a long time.

According to a third aspect of the present invention, the gap between the upper end of the cylindrical cathode and the upper flange which oppose each other concentrically is 1.
By setting it to 5 to 5 mm, even if foreign matter in the dirty water clogs between the electrodes or the hollow part of the aluminum anode, the dirty water is made to flow from the gap between the upper flange and the upper end of the cathode.
It is possible to use only the purification function of the lower filtration section without stopping the entire purification function of dirty water.

The radius of the aluminum anode 36 is R, and the aluminum anode 36 and the cathode 35 are the agglomerates.

Below the holding plate 37, there is provided a filter section composed of a filter medium 38 made of alumina balls, glass balls, activated carbon or the like, and a filter bed 39 for preventing the filter medium 38 from flowing out is provided between the filter plate 39 and the discharge port 41. It is provided.

The operation and action of the purifying apparatus constructed as above will be described below.

When a coagulation voltage is applied between the aluminum anode 36 and the cathode 35, aluminum hydroxide is generated between the electrodes, and the aluminum hydroxide passes through the holding plate 37 to form a thin layer on the surface of the filter medium 38 of the filtering section. . Bathtub 21 circulated and supplied by pump 25
The dirty water 22 of the above enters from the inlet 27 of the septic tank 20, is supplied into the cylinder 34 by the diffusion plate 33, passes between the electrodes, and the holding plate 3
It is supplied to the surface of the filtration section through the notch 42 of 7. At this time, the dirt in the dirty water 22 is electrically aggregated with aluminum hydroxide to increase the particle size, and is collected between the filter media 38 of the filtration section, and clean water is discharged from the lower part of the septic tank by the pump 35. It is sent to the bathtub through the return pipe 26 and the bath adapter 23.

As described above, in this embodiment, the cathode 3
By providing the upper end 50 of the No. 5 closer to the upper flange 28 than the aluminum anode 36, the dirty water entering from the inlet changes its flow in the outer peripheral direction by the diffusion plate 33 and hits the upper end of the cathode near the upper flange 28, and the dirty water of the cathode and the anode. Since it passes through the gaps and passes through the cutouts 42 of the holding plate 37 to the outlet from the filtration unit, the aggregating material such as aluminum hydroxide generated by applying between the electrodes accumulates between the electrodes or blocks the electrodes. Instead, it flows to the surface of the filtration unit, so effective purification can be obtained for a long period of time.

Further, since the upper end of the cathode of this embodiment is provided at the height between the diffusion plate and the upper flange 28, the dirty water entering from the inlet changes its flow in the outer peripheral direction by the diffusion plate 33 and diffuses. Most of the dirty water hits the upper end of the cathode closer to the upper flange 28 than the plate 33, and the aggregating material such as aluminum hydroxide generated by applying between the electrodes flows to the lower surface of the lower filter by the dirty water flowing between the electrodes. Therefore, effective purification can be obtained for a long period of time.

In addition, when the gap of the upper flange 28 at the upper end of the cathode of this embodiment is 1.5 to 5 mm, when the gap between the electrodes or the hollow portion of the aluminum anode is clogged with foreign matter in dirty water. Also, by flowing the dirty water through the gap between the upper flange 28 and the cathode upper end, it is possible to use only the cleaning function of the lower filter section without stopping the entire cleaning function of the dirty water.

[0022]

As described above, according to the first and second aspects of the invention, water generated by applying a voltage between the electrodes of the cathode concentrically opposed to the cylindrical aluminum anode in the septic tank. Since the aggregating material such as aluminum oxide accumulates between the electrodes and flows on the surface of the filtering portion without blocking the gap between the electrodes, it can be effectively purified for a long period of time.

According to the third aspect of the present invention, even if the electrodes are closed, they can be used without stopping the entire purification function.
