Description

Technical Field

[0001] This utility model relates to the field of electrode plate descaling technology, and in particular to a descaling structure for electrode plate surface of wastewater treatment. Background Technology

[0002] Electrocatalytic oxidation technology directly degrades organic pollutants through electrode reactions under an applied electric field, or utilizes the catalytic activity of electrodes or catalytic materials to generate a large number of highly oxidizing free radicals to degrade organic pollutants. Due to its outstanding oxidation capacity, low requirements for reaction conditions, and low likelihood of causing secondary pollution, electrocatalytic oxidation technology is considered the most promising method for application.

[0003] Electrocatalytic oxidation equipment, also known as electrocatalytic oxidation devices or electrocatalytic oxidation reactors, is a high-level electrochemical process for wastewater treatment. Developed to address the problems of high-concentration, recalcitrant wastewater and substandard biochemical treatment, it is a highly efficient and practical treatment device primarily used for treating high-concentration, high-salt, and high-COD wastewater, as well as for the advanced treatment of wastewater after biochemical treatment. The equipment utilizes an external power source, where composite electrodes within the reactor undergo an electrochemical reaction with the wastewater. The main functional module of the electrocatalytic oxidation equipment is the anode structure, which is often made of titanium metal with a noble metal coating as a catalytic layer. Under the influence of an external electric field, the wastewater or liquid to be treated is introduced into the electrolytic cell. Under the influence of the current, active groups such as hydroxyl radicals are generated on the surface of the electrode materials to oxidize the organic matter in the water, decomposing it into CO2, H2O, and small molecule organic matter. This reduces COD, ammonia nitrogen, color, and improves biodegradability in the water.

[0004] In the electrocatalytic wastewater treatment process, as the filtration time increases, dirt will be adsorbed on the surface of the electrode plates. However, existing electrocatalytic oxidation wastewater treatment equipment usually does not have the function of automatically cleaning the dirt on the electrode plate surface (e.g., Chinese utility model patent with application number: 202223086335.9, title: An Electrocatalytic Oxidation Wastewater Treatment Equipment). In the electrocatalytic wastewater treatment process, it is necessary to ensure that the wastewater is in contact with the electrode plates to achieve the purification function. Once the electrode plates are adsorbed with too much dirt, it will affect the contact between the wastewater and the electrode plates, thereby affecting the effect and efficiency of wastewater purification. This has certain limitations and needs to be improved.

[0005] Therefore, it is necessary to provide a descaling structure for the surface of an electrode plate used in wastewater treatment to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a descaling structure for electrode plates used in wastewater treatment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a descaling structure for the surface of an electrode plate for sewage treatment, comprising a rotating shaft movably inserted and installed at the middle position of the electrode plate, the rotating shaft being driven to rotate by an external drive source, and an intermediate descaling component being fixedly sleeved on the outer surface of the rotating shaft.

[0008] The intermediate descaling component includes a brush rod fixedly sleeved on the outer surface of a rotating shaft, and a descaling scraper is fixedly installed on one side of the brush rod by bolts.

[0009] It also includes a four-sided descaling component, which includes a rotating shaft 2 that is rotatably installed at the four corners of the electrode plate. Both ends of the rotating shaft 2 are fixedly connected to ratchet wheels, and multiple descaling scraper blades 2 are fixedly connected to the opposite side of the two ratchet wheels.

[0010] The rotating middle descaling component cleans the dirt in the middle of the electrode plate, and when the rotating middle descaling component comes into contact with the surrounding descaling components, it pushes the surrounding descaling components to rotate and clean the dirt adsorbed at the four corners of the electrode plate.

[0011] In practical applications, when cleaning the electrode plates is required, an external drive source drives the rotating shaft to rotate, which in turn drives the brush rod to rotate synchronously. This, in turn, causes the descaling scraper to move in a circular motion around the axis of the rotating shaft, scraping away the dirt adsorbed in the center of the electrode plate. Simultaneously, during the circular motion of the brush rod, when it rotates to abut against the ratchet, it pushes the ratchet to rotate. The rotation of the ratchet then drives the descaling scraper to rotate, which in turn scrapes away the dirt adsorbed at the four corners of the electrode plate. By cleaning the dirt adsorbed on the surface of the electrode plate, the cleanliness of the electrode plate surface can be improved, which is conducive to the full contact between the wastewater and the electrode plate, thereby improving the efficiency and effect of wastewater purification.

[0012] As a further description of the above technical solution: the end of the brush rod away from the rotating shaft is provided with a bevel, and each tooth of the ratchet is provided with a bevel. The bevels and the bevel make it easier for the brush rod to drive the ratchet to rotate.

[0013] As a further description of the above technical solution: the first rotating shaft adopts a hexagonal shaft.

[0014] As a further description of the above technical solution: both the first descaling scraper and the second descaling scraper are made of rubber.

[0015] As a further description of the above technical solution: the end of the first descaling scraper away from the brush rod is abutted against the electrode plate, and the end of the second descaling scraper is abutted against the electrode plate.

[0016] This utility model has the following beneficial effects:

[0017] Compared with existing technologies, this descaling structure for the electrode plate surface in wastewater treatment, through the rotation of the rotating shaft, drives the central descaling component to rotate and clean the dirt in the middle of the electrode plate. When the central descaling component rotates to contact the surrounding descaling components, it pushes the surrounding descaling components to rotate and clean the dirt adsorbed at the four corners of the electrode plate. By cleaning the dirt adsorbed on the electrode plate surface, the cleanliness of the electrode plate surface can be improved, which is conducive to the full contact between wastewater and the electrode plate, thereby improving the efficiency and effect of wastewater purification.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-4The present invention provides a descaling structure for the surface of an electrode plate for sewage treatment: including a rotating shaft 1 movably inserted and installed in the middle position of the electrode plate 4. The rotating shaft 1 is a hexagonal shaft. The rotating shaft 1 is movably inserted in the strip-shaped notch in the middle position of the electrode plate 4. The rotating shaft 1 is driven to rotate by an external drive source. An intermediate descaling component 2 is fixedly sleeved on the outer surface of the rotating shaft 1.

[0026] The intermediate descaling component 2 includes a brush rod 201 fixedly sleeved on the outer surface of the rotating shaft 1. A descaling scraper 203 is fixedly installed on one side of the brush rod 201 by bolts 202. An inclined surface 204 is provided at the end of the brush rod 201 away from the rotating shaft 1.

[0027] It also includes a four-sided descaling component 3, which includes a rotating shaft 301 that is rotatably installed at the four corners of the electrode plate 4. Both ends of the rotating shaft 301 are fixedly connected to ratchet 302. On the opposite side of the two ratchet 302, multiple descaling scrapers 303 are fixedly connected. Each tooth of the ratchet 302 is provided with a bevel 304.

[0028] Two sets of middle descaling components 2 are installed in mirror symmetrically on both sides of the electrode plate 4. Eight sets of perimeter descaling components 3 are installed in mirror symmetrically at the four corners of the front and back of the electrode plate 4, that is, a set of perimeter descaling components 3 is installed at the four corners of the front and back of the electrode plate 4.

[0029] An external drive source drives the rotating shaft 1 to rotate, which in turn drives the intermediate descaling component 2 to rotate and clean the dirt in the middle of the electrode plate 4. When the intermediate descaling component 2 rotates to contact the surrounding descaling components 3, it pushes the surrounding descaling components 3 to rotate and clean the dirt adsorbed at the four corners of the electrode plate 4. By cleaning the dirt adsorbed on the surface of the electrode plate 4, the cleanliness of the surface of the electrode plate 4 can be improved, which is conducive to the full contact between the sewage and the electrode plate 4, thereby improving the efficiency and effect of sewage purification treatment.

[0030] Both the descaling scraper 1 (203) and the descaling scraper 2 (303) are made of rubber.

[0031] The end of the first descaling scraper 203 away from the brush rod 201 is abutted against the electrode plate 4, and the end of the second descaling scraper 303 is abutted against the electrode plate 4.

[0032] Working principle: When cleaning of electrode plate 4 is required, an external drive source drives the rotating shaft 1 to rotate, which in turn drives the brush rod 201 to rotate synchronously. This, in turn, drives the descaling scraper 203 to make a circular motion around the axis of the rotating shaft 1, thereby scraping away the dirt adsorbed in the middle of the electrode plate 4. At the same time, during the circular motion of the brush rod 201, when the brush rod 201 rotates to abut against the ratchet 302, it will push the ratchet 302 to rotate. In turn, the rotation of the ratchet 302 will drive the descaling scraper 303 to rotate, and the rotating descaling scraper 303 will scrape away the dirt adsorbed at the four corners of the electrode plate 4. By cleaning the dirt adsorbed on the surface of the electrode plate 4, the cleanliness of the surface of the electrode plate 4 can be improved, which is conducive to the full contact between the sewage and the electrode plate 4, thereby improving the efficiency and effect of sewage purification treatment.
