Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment devices, specifically a dye wastewater treatment device. Background Technology

[0002] Dye wastewater is difficult to treat due to its complex composition, high color, high toxicity, and difficulty in degradation. If discharged without effective treatment, it will cause serious harm to the ecological environment and human health. Electrocoagulation is a highly efficient electrochemical water treatment method. It generates flocculants by electrolyzing metal anodes, which effectively removes color, suspended solids, and heavy metals from dye wastewater. As a consumable material for electrocoagulation, the electrode plate needs to be cleaned regularly during use and replaced with a new one after a certain period of use.

[0003] For example, patent number CN215049358U discloses a novel electrocoagulation decolorization device for dye wastewater. This device includes components such as a flocculation tank, a hydraulic cylinder, a support frame, a scraper, and electrode plates. Through the cooperation of the hydraulic cylinder, the boom, and the support frame, two sets of electrode plates can be alternated when it is necessary to replace the electrode plates. The scraper is used to clean the electrode plates during the reaction. However, the scraper of this device can only remove the flocculent material attached to the bottom of the electrode plates. Moreover, the contact between the electrode plates and the scraper during the reaction will reduce the reaction efficiency. When the hydraulic cylinder lifts the support frame, the electrode plates tilt at the same time, causing the wastewater on the electrode plates to drip. Furthermore, this structure prevents the electrode plates from being completely submerged in the flocculation tank. The part of the electrode exposed to the air cannot participate in the reaction, reducing the treatment efficiency. Corrosion occurs at the liquid surface interface due to the oxygen concentration difference.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

A filter screen 7 is provided at the output port.

[0017] The outer part of the annular toothed guide rail 3 is a toothed wheel, and the bottom is provided with an annular limiting block 13. The annular limiting block 13 cooperates with the annular limiting groove 8 at the top of the flocculation tank. The toothed wheel of the annular toothed guide rail 3 is engaged with a gear 15. A first motor 14 is provided below the gear 15. The first motor 14 is fixed above the ear plate 6 on the outer wall of the flocculation tank 2.

[0018] The lifting electrode plate structure 5 includes an electric push rod 19, an electrode plate 20, an arc-shaped fixing frame 22, and a boom 21. The electrode plate 20 is arc-shaped. The top of the electric push rod 19 is fixedly connected to the boom 21. The lower end of the boom 21 is connected to the top of the arc-shaped fixing frame 22 by threaded bolts. The electrode plate 20 is embedded in the arc-shaped fixing frame 22.

[0019] The gear 15 is provided with a fixed wheel 16 at the top. The gear 15 is rotatably connected to the upper part of the ear plate 6. The bottom of the fixed wheel 16 covers the top surface of the annular toothed guide rail 3. The outer wall of the middle part of the limiting wheel 17 is tangent to the outer wall of the annular toothed guide rail 3, and the top of the limiting wheel 17 covers the top surface of the annular toothed guide rail 3. The limiting wheel 17 and the fixed wheel 16 are used to prevent the annular toothed guide rail 3 from disengaging from the annular limiting groove 8 when rotating.

[0020] The stirring structure 4 includes a second motor 9, a stirring paddle 12, a stirring shaft 11, and a support frame 10. The support frame 10 is set above the flocculation tank 2, with both ends fixed to the outer wall of the flocculation tank 2 and a through hole in the center. The stirring shaft 11 is provided with three sets of stirring paddles 12 from bottom to top. The second motor 9 is fixed directly above the through hole of the support frame 10, and the upper end of the stirring shaft 11 passes through the through hole of the support frame 10 to connect to the second motor 9.

[0021] The annular toothed guide rail 3 is provided with symmetrically distributed scrapers 18. The scrapers 18 are arc-shaped corresponding to the curvature of the electrode plate 20. They are provided with U-shaped grooves 25 corresponding to the thickness of the electrode plate 20. The U-shaped grooves 25 are connected vertically. The bottom surface of the scrapers 18 is an outward-facing slope, which facilitates cleaning the surface of the electrode plate 20. The outer wall is provided with fixing plates 23 at both ends.

[0022] During use, dye wastewater is added to flocculation tank 2. The electric actuator 19 is lowered, driving the boom 21 to submerge the electrode plate 20 in the dye wastewater. When the electrode plate 20 is energized, an electrocoagulation reaction occurs. The second motor 9 drives the stirring shaft 11 to rotate, which in turn drives the stirring paddle 12 to rotate, promoting floc growth. When there is excessive buildup on the surface of the electrode plate 20, requiring cleaning, the electric actuator 19 raises the boom 21 to a position slightly above the scraper 18. The first motor 14 drives the gear 15 to rotate clockwise, causing the annular toothed guide rail 3 to rotate counterclockwise. Simultaneously, this rotates the U-shaped groove 25 in the scraper 18 fixed in the limiting groove 24, causing the electrode plate... Electrode plate 20 is embedded in the U-shaped groove 25 of scraper 18. Electric push rod 19 is raised again. While the electrode plate 20 is being raised, the adhering substances on its surface are scraped off by scraper 18. When electric push rod 19 is raised to the highest point, electrode plate 20 is disengaged from U-shaped groove 25. When replacing electrode plate 20, it is necessary to raise electrode plate 20 to the highest point or to lower electrode plate 20 into flocculation tank 2. First motor 14 drives gear 15 to rotate counterclockwise, which drives the annular toothed guide rail 3 to rotate clockwise, so that scraper 18 avoids electrode plate 20 and boom 21. Wastewater after electrocoagulation is filtered through filter screen 7 at the bottom of flocculation tank 2 to remove flocculent matter and is discharged from the outlet at the bottom of flocculation tank 2.
