More particularly, the present invention relates to an electrode structure for an ozone generator, To an electrode structure for an ozone generating device and to an ozone generating device using the electrode structure.

Generally, an electrolytic ozone generator is configured to generate ozone through electrolysis by applying positive (+) potential and negative (-) potential to two electrodes. Typically, the electrodes for the ozone generator are provided in the form of a wire or in the form of a plate.

Korean Patent Registration No. 10-0359201 discloses an electrode for an ozone generating device in which a spiral electrode is disposed outside a center electrode. Thus, in the case of using a wire-shaped electrode, it is difficult to manufacture, and when the wire is broken, there is a problem that the ozone generator is disabled.

On the other hand, Korean Patent No. 10-0381271 discloses an ozone generator equipped with stripe-shaped electrodes. According to the prior art, the shape of the electrode plate is implemented in a stripe shape so that overlapping discharge areas are avoided and a given area is efficiently used. However, since the interelectrode spacing formed by the stripe shape is vertically aligned, the flow path of the fluid is short and simple. Accordingly, when the electrode is used for a long period of time, the flow of water between the electrode located at the upper portion and the electrode located at the lower portion is weakened, so that the scale is stacked on the electrode plate and the efficiency of generating ozone is lowered.

The edge coupling member 400 is coupled to the rim of the upper electrode plate 100 and the lower electrode plate 200 so that the upper electrode plate 100 and the lower electrode plate 200 are fixedly coupled with a predetermined spacing do.

Specifically, the upper electrode plate 100 is formed so that the left half and the right half have different electrode arrangements. The left half of the upper electrode plate 100 is formed with a plurality of arc-shaped fluid flow paths forming a concentric circle with respect to the center thereof to form the first upper electrode array 110, and the right half portion forms a concentric circle with respect to the center A plurality of arc-shaped fluid flow paths are formed, and a fluid channel is formed asymmetrically with the first upper electrode array 110 to form a second upper electrode array 120.

A flange coupling part 130 to which the flange unit is coupled is extended to one side of the upper electrode plate 100 and a flange coupling hole 135 for coupling with the flange unit is formed on the flange coupling part 130. The electrode lead-out portion 140 is extended from the flange coupling portion 130 and the terminal lead-out hole 145 is formed on the electrode lead-out portion 140. Since the flange coupling part 130 and the electrode lead part 140 are integrally formed in the upper electrode plate 100 as described above, a connector for connecting the upper electrode to the terminal is not required separately, It is possible to prevent defects and minimize required parts.

Like the upper electrode plate 100, the lower electrode plate 200 has different electrode arrangements in the right and left halves. The first lower electrode array 210 formed on the left half of the lower electrode plate 200 is disposed opposite to the first upper electrode array 110 of the upper electrode plate 100, The first upper electrode array 110 and the second upper electrode array 110 are formed.

The fluid channel 214 of the fluid channel 214 is also shifted. Accordingly, as shown by the arrows in FIG. 3, the passage through which the fluid (e.g., sewage discharged through the sewer installed with the ozone generator) flows forms various paths and can be distributed through more electrodes. As a result, the flow of the fluid is smooth and the scale can be prevented from accumulating on the electrode even after a long period of use.

A rim spacer 440 is formed at a central portion of the rim coupling member body 410 to protrude inward to separate the upper electrode plate 100 and the lower electrode plate 200 from each other by a predetermined distance.

2, the upper electrode plate 100 and the lower electrode plate 200 are coupled to each other by a frame coupling member 400 and are spaced apart by a predetermined distance by the center spacer 300 and the frame spacer 440 .

Referring to FIG. 4, the combined electrode structure can be coupled to the flange unit 500 as shown in FIG. The flange unit 500 has a structure in which a flange sealing member 540 is interposed between the upper flange 530 and the lower flange 550. A plurality of fastening holes 510 are formed along the circumference of the upper flange 530 and the lower flange 550. The upper and lower flanges are coupled and fixed by fastening the bolts to the fastening holes. An electrode fastener 520 for coupling the electrode structure of FIG. 2 is formed on the upper flange 530 and the lower flange 550, and a pair of electrode plates can be fixedly coupled on the upper and lower flanges.

An inlet 910 through which the fluid flows is formed at the lower end of the lower housing 900 and an outlet 810 through which the fluid flows out is formed at the upper end of the upper housing 800.

A flange unit 500 as shown in FIG. 4 is coupled between the upper housing 800 and the lower housing 900. At this time, since the upper housing 800 and the lower housing 900 have a dome shape, they have high pressure resistance, and in the process of flowing the fluid introduced through the lower inlet 910 through the outlet 810 at the upper end Fluid can be evenly distributed inside the upper and lower dome structures by the inflow pressure of the fluid. Accordingly, the entire area of the lower electrode plate 200 and the upper electrode plate 100 can be efficiently used to generate ozone.

As shown in FIG. 5, a plurality of flange units 500 may be installed between the upper housing 800 and the lower housing 900.

Here, the first flange unit 500 and the second flange unit 600 respectively accommodate the electrode structure of FIG. 2 described above. The first flange upper electrode withdrawing portion 560 and the first flange lower electrode withdrawing portion 580 are drawn out to both sides of the first flange unit 500 as shown. Further, the second flange upper electrode withdrawing portion 660 and the second flange lower electrode withdrawing portion 680 are drawn out to both sides of the second flange unit 600.

That is, two pairs of electrode structures shown in Fig. 2 may be provided in the ozone generating device. Of course, two or more pairs of electrode structures may be provided. The electrode structure for the ozone generator according to the present invention is provided in the form of a plate as described above. However, as shown in FIG. 3, the upper electrode plate 100 and the lower electrode plate 200 have arc-shaped fluid passages 114, 214, and can have an effect similar to that of forming a wire electrode by widening the contact area of the fluid with respect to the upper electrode 112 and the lower electrode 212.

Furthermore, by arranging the upper electrode and the lower electrode to be shifted from each other, it is possible to variously induce the flow path of the fluid passing through the fluid channel. Therefore, it is possible to prevent the scale from being stacked on the surface of the electrode for a long period of time.
