[0043] The utility model provides an electrocatalytic oxidation device for convenient impurity removal. When in use, wastewater in the wastewater pool enters the catalytic oxidation shell 2 from the first conveying component 8 and the water inlet pipe 4, and then is electrocatalytically oxidized by the conductive electrode 7. At the same time, the catalytic effect, conductivity and oxidation functions are increased by the honeycomb ceramic catalyst sheet 18 and the high-conductivity wafer electrode plate 19 with drainage holes. After that, the clarified water in the upper half of the catalytic oxidation shell 2 enters the collection tank from the second conveying component 9, and then the external controller controls the solenoid valves on the water inlet pipe 4 and the water outlet pipe 5 to be closed, and opens the solenoid valve on the cleaning pipe 6, so that the water in the external cleaning water tank can be discharged from the water delivery pipe 10 and the water outlet pipe 5. The cleaning pipe 6 enters the catalytic oxidation shell 2 to clean and remove impurities from the interior of the catalytic oxidation shell 2. During cleaning, the driving component 15 drives the connecting rod 11 to rotate, so that the brush 12 can clean the high-conductivity wafer electrode plate 19 above it. Then, the controller controls the solenoid valve on the drain pipe 17 to open, so that the wastewater and light impurities in the catalytic oxidation shell 2 can be discharged from the drain pipe 17 into the collection tank 16. During the discharge, the scraper 14 on the inner wall of the catalytic oxidation shell 2 can rotate under the drive of the connecting rod 11 and the T-shaped rod 13, so that the impurities at the bottom of the catalytic oxidation shell 2 can be scraped to the drain pipe 17, thereby improving the impurity removal effect.

[0044] Also note: The power supply uses a high-frequency pulse rectifier voltage of 500VDC, which is extremely efficient in treating sewage. The output voltage has a wide adjustment range and features soft start, soft shutdown, constant current, current limiting, and overcurrent protection.

[0045] Furthermore, the catalytic oxidation shell 2 includes a processing tube 21 fixedly mounted on the mounting bracket 1 by a rubber-coated U-shaped clip 3, and sealing cylinders 22 are provided at the upper and lower ends of the processing tube 21.

[0047] Furthermore, the number of the cleaning tubes 6 and the number of the conductive electrodes 7 are both two, and the two cleaning tubes 6 and the two conductive electrodes 7 are fixedly mounted on the two sealing cylinders 22 respectively.

[0048] Specifically, the two cleaning tubes 6 and the two conductive electrodes 7 can improve the electrocatalytic oxidation effect and the cleaning effect.

[0049] Furthermore, the driving assembly 15 includes two groups of L-shaped frames 1501 symmetrically installed on the inner bottom wall of the mounting bracket 1, and a rotating rod 1502 is provided in the middle of the two groups of L-shaped frames 1501, and both ends of the rotating rod 1502 are rotatably connected to the L-shaped frames 1501. A plurality of active bevel gears 1503 are fixedly installed on the outer walls of the two rotating rods 1502 from left to right, and a driven bevel gear is fixedly installed at the bottom of the connecting rod 11, and the active bevel gear 1503 is meshed with the driven bevel gear. A motor 1504 is fixedly installed on one side of the L-shaped frame 1501 through a fixed frame, and the output end of the motor 1504 is rotatably connected to the rotating rod 1502.

[0050] Specifically, the motor 1504 drives the rotating rod 1502 and the driving bevel gear 1503 on the rotating rod 1502 to rotate, and then the rotating driving bevel gear 1503 rotates through the driven bevel gear meshing with it, thereby rotating the connecting rod 11, thereby enabling the brush 12 and the scraper 14 to clean and scrape the interior of the catalytic oxidation shell 2.

[0051] Furthermore, the first conveying assembly 8 includes two conveying pipes 81 symmetrically fixedly mounted on the mounting bracket 1, and the other end of the water inlet pipe 4 is fixedly connected to the conveying pipe 81. One end of the two conveying pipes 81 is connected with a three-way joint 82, and the other end of the three-way joint 82 is fixedly mounted with a connecting pipe 83.

[0052] Specifically, the wastewater in the wastewater pool can be transported from the water inlet pipe 4 to the catalytic oxidation shell 2 for electrocatalytic oxidation through the delivery pipe 81 , the three-way joint 82 and the connecting pipe 83 .

[0053] It should also be noted that the structure of the second conveying assembly 9 is the same as that of the first conveying assembly 8, so no further description is given. Then, one end of the connecting pipe 83 connected to the wastewater tank is connected near the bottom of the wastewater tank. In this way, water can be transported from the first conveying assembly 8 and the water inlet pipe 4 to the catalytic oxidation shell 2 through the natural height difference. Example
