The box body is divided into an impurity removal chamber and a catalytic oxidation chamber by a partition. The top of the impurity removal chamber is connected to a water inlet pipe, the bottom of the catalytic oxidation chamber is provided with a water outlet pipe, a pumping component is connected between the impurity removal chamber and the catalytic oxidation chamber, and an anode plate and a cathode plate are slidably arranged in the catalytic oxidation chamber. When electrocatalytically oxidizing sewage, the sewage enters the impurity removal chamber from the water inlet pipe, the pumping component pumps the liquid into the catalytic oxidation chamber, the anode plate and the cathode plate are electrified, and the sewage is electrocatalytically oxidized. When electrocatalytically oxidizing sewage with different water qualities, the anode plate and the cathode plate are slid to adjust the distance between the anode plate and the cathode plate to improve the wastewater treatment effect.

[0004] In the process of implementing the present application, the inventor found that there are at least the following problems in this technology: during the electrocatalytic oxidation of sewage, scaling will occur on the anode plate and the cathode plate, resulting in an increase in the operating power consumption of the equipment and a decrease in the sewage treatment effect. Therefore, it is necessary to manually maintain the anode plate and the cathode plate regularly. Summary of the Utility Model

[0005] In order to extend the frequency of manual maintenance of the electrode plates and reduce the decline of the sewage treatment effect, the present application provides a wastewater treatment device based on electrocatalytic oxidation.

[0006] The wastewater treatment device based on electrocatalytic oxidation provided by the present application adopts the following technical solutions:

A group of electrode plates are slidably arranged in the box body. Through holes are formed through the electrode plates. An insulating ring seat is rotatably arranged in the through holes. A plurality of scraping plates are arranged at both ends of the insulating ring seat. The scraping plates are in contact with the electrode plates. A driving shaft is rotatably arranged in the box body. The insulating ring seats are sleeved on the driving shaft, and the insulating ring seats are slidably connected to the driving shaft.

[0008] By adopting the above technical solution, when electrocatalytic oxidation of sewage is carried out, the sewage enters the box body from the water inlet pipe, and the electrode plates are electrified to carry out electrocatalytic oxidation treatment on the sewage. During the electrocatalytic oxidation process of the sewage, the driving shaft rotates to drive the insulating ring seat to rotate, and the insulating ring seat drives the scraper to rotate, so that the scraper rotates relative to the electrode plates, and the scraper scrapes the substances on the surface of the electrode plates. When electrocatalytic oxidation treatment is carried out on sewage with different water qualities, the electrode plates slide to change the distance between the electrode plates, improving the wastewater treatment effect. At the same time, the electrode plates drive the insulating ring seat to move synchronously, so that the scraper on the insulating ring seat always abuts against the electrode plates. By scraping the surface of the electrode plates with the scraper, the scaling on the surface of the electrode plates is reduced, the frequency of manual maintenance of the electrode plates is prolonged, and the decline of the sewage treatment effect is reduced.

[0010] By adopting the above technical solution, the insulating ring seat is rotatably connected with the electrode plates through the connecting ring groove and the connecting ring seat. When the electrode plates move, the electrode plates drive the connecting ring seat to move, and the connecting ring seat drives the insulating ring seat to move synchronously, so that the insulating ring seat moves relative to the driving shaft. When the driving shaft drives the insulating ring seat to rotate synchronously, the insulating ring seat drives the connecting ring seat to rotate, and the connecting ring seat rotates in the connecting ring groove, so that the insulating ring seat rotates relative to the electrode plates.

[0012] By adopting the above technical solution, the insulating ring seat is slidably connected with the driving shaft through the connecting sliding groove and the connecting sliding block. When the electrode plates drive the insulating ring seat to move synchronously, the connecting sliding block moves along the connecting sliding groove, so that the insulating ring seat moves relative to the driving shaft. When the driving shaft rotates, the driving shaft drives the connecting sliding block to rotate, and the connecting sliding block drives the insulating ring seat to rotate, so that the insulating ring seat rotates relative to the electrode plates.

[0016] By adopting the above technical solution, when the insulating ring seat rotates, the insulating ring seat drives the scraping seat to rotate, and the rotation of the scraping seat drives the scraping strip to rotate relative to the electrode plate. When the scraping strip is severely worn, the old scraping strip is taken out of the scraping groove, and a new scraping strip is installed in the scraping groove, so as to facilitate the scraping of the substances on the surface of the electrode plate by the scraper.

[0018] By adopting the above technical solution, when the fixing screw is in threaded connection with the fixing groove and the fixing screw is inserted into the fixing hole on the scraping strip, the scraping strip is limited in the scraping groove. When replacing the scraping strip, the fixing screw is rotated to move the fixing screw out of the fixing hole, achieving the effect of detachable connection between the scraping strip and the scraping seat.

[0019] Preferably, an adjusting screw rod is rotatably arranged in the box body. The adjusting screw rod includes a forward threaded section and a reverse threaded section. A forward sliding seat is in threaded connection with the forward threaded section, and a reverse sliding seat is in threaded connection with the reverse threaded section. The forward sliding seat is fixedly connected to one of the electrode plates, and the reverse sliding seat is fixedly connected to the other electrode plate.

During the electrocatalytic oxidation process of the sewage, the driving motor 51 starts to drive the driving shaft 5 to rotate. The rotation of the driving shaft 5 drives the insulating ring seat 3 to rotate, and the insulating ring seat 3 drives the scraper 4 to rotate, causing the scraper 4 to rotate relative to the electrode plate 2. The scraper 4 scrapes the substances on the surface of the electrode plate 2. When electrocatalytically oxidizing sewage with different water qualities, the adjusting motor 8 starts to drive the electrode plate 2 to slide, thereby changing the distance between the electrode plates 2 and improving the wastewater treatment effect. At the same time, the electrode plate 2 drives the insulating ring seat 3 to move synchronously, so that the scraper 4 on the insulating ring seat 3 always abuts against the electrode plate 2. By scraping the surface of the electrode plate 2 with the scraper 4, the scaling on the surface of the electrode plate 2 is reduced, the frequency of manual maintenance of the electrode plate 2 is extended, and the decline in the sewage treatment effect is reduced.
