Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 4 , the utility model provides a technical solution:

[0026] The electrocatalytic oxidation device includes a treatment box 1, a water inlet valve hole 3 is opened on the lower side of the right end surface of the treatment box 1, and a drain valve hole 2 is opened on the upper side of the left end surface of the treatment box 1. A sewage outlet 4 is opened on the lower side of the left end surface of the treatment box 1, and a valve is installed in the sewage outlet 4;

[0027] Electrode rods 5 are fixedly connected to the inside of the processing box 1 at equal distances, and filter plates 6 are penetrated by the electrode rods 5. The electrode rods 5 are distributed on the front and back sides of the filter plates 6. A scraper 12 is fixed at the penetration point between the filter plates 6 and the electrode rods 5. The electrode rods 5 are located inside the scraper 12 and are designed to fit the inner wall of the scraper 12.

[0028] Specifically, sliders 11 are fixedly connected around the filter plate 6 , and a sliding groove 8 is opened at a position on the inner wall of the processing box 1 corresponding to the sliding groove 11 , and the sliding groove 11 is slidably connected in the sliding groove 8 .

[0029] Specifically, a cleaning scraper 13 is movably connected to the left side of the lower end surface of the filter plate 6 , a slide rail 14 is fixed to the upper end surface of the cleaning scraper 13 , and the cleaning scraper 13 is slidably connected to the filter plate 6 through the slide rail 14 .

[0030] Specifically, a through hole 10 is formed through the left sliding block 11 of the filter plate 6 , and a steel wire rope 7 is movably connected in the through hole 10 .

[0031] Specifically, the top of the wire rope 7 is fixed to the upper side of the inner chute 8, and the other end extends to the lower side of the filter plate 6 and is fixed to the middle of the cleaning scraper 13. When the filter plate 6 moves downward, the wire rope 7 guides and pulls the cleaning scraper 13 through the guide wheel 9, and the cleaning scraper 13 moves from right to left on the lower end surface of the filter plate 6 via the slide rail 14.

[0032] Specifically, the left side of the lower end surface of the filter plate 6 is rotatably connected to a guide wheel 9, and the steel wire rope 7 passes through the outside of the guide wheel 9. The steel wire rope 7 is made of corrosion-resistant metal material.

[0033] Specifically, a fixing plate 16 is fixedly connected to the lower end surface of the filter plate 6 near the cleaning scraper 13, and a wavy elastic sheet 15 is fixedly connected between the fixing plate 16 and the cleaning scraper 13. The cleaning scraper 13 moves from right to left on the lower end surface of the filter plate 6 through the slide rail 14 and pulls the wavy elastic sheet 15. After the device is restarted, the filter plate 6 floats up and resets, and the cleaning scraper 13 is reset under the action of the elastic sheet 15.

[0034] Specifically, the filter plate 6 is made of polyethylene material. The filter plate 6 can also be made of other lightweight materials as long as it is ensured to rise under the buoyancy of the sewage inside the treatment box 1.

[0035] Working principle: During operation, sewage enters the treatment box 1 through the water inlet valve hole 3, and then is discharged to the outside through the drain valve hole 2. The sewage outlet 4 is in a closed state when the treatment box 1 treats sewage. The filter plate 6 is located on the top of the electrode rod 5 under the injection of internal sewage and does not separate from the electrode rod 5. The top of the electrode rod 5 is a T-shaped structure, and the polyethylene material of the filter plate 6 has the characteristics of light weight and can rise under the buoyancy of sewage. During the sewage treatment process of the treatment box 1, the electrode rod 5 is conductive and treats the internal sewage, and the filter plate 6 further filters the sewage. When there are more impurities attached to the surface of the electrode rod 5, the user stops injecting sewage into the treatment box 1 and opens the sewage outlet 4 to discharge the sewage inside the treatment box 1. Then, as the sewage in the treatment box 1 decreases, the filter plate 6 moves down steadily through the slider 11 and the chute 8 under its own weight and the counterweight of the slider 11, and the filter plate 6 During the downward movement, the bottom of the scraper 12 fits against the surface of the electrode rod 5, scraping and cleaning the attachments on the surface of the electrode rod 5 to the bottom of the treatment box 1, and during the downward movement of the filter plate 6, the wire rope 7 guides and pulls the cleaning scraper 13 through the guide wheel 9. The cleaning scraper 13 moves from right to left on the lower end surface of the filter plate 6 through the slide rail 14 and pulls the wavy elastic sheet 15. After the device is restarted, the filter plate 6 floats and resets, and the cleaning scraper 13 is reset under the action of the elastic sheet 15, scraping and cleaning the lower end surface of the filter plate 6, and the cleaned pollutants also fall to the bottom of the treatment box 1. At this time, the user plugs the external high-pressure flushing pipe into the water inlet valve hole 3 to flush the impurities accumulated on the lower side of the filter plate 6. The flushed impurities are discharged to the outside world through the sewage outlet 4 again. The filter plate 6 can also be made of other lightweight materials to ensure that it rises under the buoyancy of the sewage inside the treatment box 1.
