Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank technology, specifically a micro-etching liquid sedimentation tank. Background Technology

[0002] With the rapid development of industry, a large amount of copper-containing micro-etching waste liquid is generated. If this waste liquid is discharged directly without proper treatment, it will cause serious environmental pollution. Currently, the main methods for treating copper-containing waste liquid include chemical precipitation, electrolysis, and adsorption. Among these, chemical precipitation is widely used due to its simple operation and good treatment effect.

[0003] Existing micro-etching waste liquid treatment devices containing copper ions typically have the following problems: the precipitate produced after the precipitant is mixed with the micro-etching waste liquid accumulates at the bottom of the sedimentation tank, which is inconvenient to clean in a timely manner and is not conducive to the collection and reuse of the precipitate.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing sedimentation tanks. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-6 This utility model provides a technical solution: a micro-etching solution sedimentation tank, including a tank body 1, a cover body 2 above the tank body 1, a scraper 3 inside the tank body 1, a drive rod 4 and a guide rod 5 respectively installed at both ends of the scraper 3, a sleeve 6 outside the drive rod 4, the sleeve 6 being fixed to the surface of the cover body 2, an adjusting ring 7 at the end of the sleeve 6 away from the cover body 2, a mating ring 8 fixed to the surface of the adjusting ring 7, and a mating groove 9 at the end of the sleeve 6 near the adjusting ring 7, with the mating ring 8 located within the mating groove 9. A drive gear 10 is provided on the outer side of the ring 7. A servo motor 11 is connected to the drive gear 10. The servo motor 11 is fixed to the surface of the sleeve 6. A float plate 12 is provided above the scraper 3. The float plate 12 is also located in the tank 1. A corrugated pipe 13 is fixed to the surface of the float plate 12. An opening is provided on the float plate 12 at the corresponding position where it is connected to the corrugated pipe 13. The end of the corrugated pipe 13 away from the float plate 12 is fixed to the surface of the cover 2. An injection pipe 14 is also installed on the cover 2. A suction straight pipe 15 is also fixed to the surface of the float plate 12.

[0027] The edge of the scraper 3 is in contact with the inner wall of the tank 1. The scraper 3 is fixedly connected to the drive rod 4 and the guide rod 5. The drive rod 4 can drive the scraper 3 to move up and down synchronously, which is conducive to the edge of the scraper 3 scraping off the sediment on the inner wall of the tank 1.

[0028] Both the drive rod 4 and the guide rod 5 are slidably connected to the cover 2, which facilitates the up-and-down movement of both the drive rod 4 and the guide rod 5 on the cover 2 and improves the stability of the scraper 3 in displacement.

[0029] The adjusting ring 7 is rotatably connected to the sleeve 6 through the docking ring 8 and the docking groove 9. The adjusting ring 7 and the drive rod 4 are connected by a thread. When the adjusting ring 7 rotates on the sleeve 6 through the docking ring 8 and the docking groove 9, the adjusting ring 7 can push the drive rod 4 to move up and down through the thread.

[0030] The surface of the adjusting ring 7 is evenly distributed with toothed blocks. The adjusting ring 7 is connected to the drive gear 10 through the toothed blocks. When the drive gear 10 rotates, the drive gear 10 can push the adjusting ring 7 to rotate synchronously through the toothed blocks.

[0031] The edge of the float plate 12 fits against the inner wall of the tank 1, which facilitates the float plate 12 to slide up and down along the inner wall of the tank 1.

[0032] The float 12 is slidably connected to the drive rod 4 and the guide rod 5 respectively, which facilitates the up and down displacement of the float 12 on the outside of the drive rod 4 and the guide rod 5.

[0033] The corrugated pipe 13 is connected to the injection pipe 14, and external waste liquid and precipitant can be injected into the tank 1 through the injection pipe 14 and the corrugated pipe 13 for precipitation.

[0034] The suction pipe 15 and the cover 2 are connected by a through sliding connection. When the float 12 moves up and down in the tank 1, the cover 2 can drive the suction pipe 15 to move synchronously, which is beneficial for the continuous suction of the waste liquid that has completed sedimentation.

[0035] Working principle: When using this micro-etching solution sedimentation tank, firstly as follows... Figures 1-6 As shown, the external waste liquid to be settled and the precipitant are injected into the tank 1 through the injection pipe 14 and the corrugated pipe 13 for sedimentation. At this time, the float plate 12 is attached to the surface of the waste liquid under the action of buoyancy. After the waste liquid has settled, the external suction equipment extracts the liquid below the float plate 12 through the suction straight pipe 15. As the liquid level drops, the float plate 12 drives the suction straight pipe 15 to descend synchronously on the cover 2, which is conducive to the continuous extraction and transfer of the settled waste liquid according to the liquid level change.

[0036] When it is necessary to clean the sediment in the tank 1, the servo motor 11 is started to drive the drive gear 10 to rotate. At this time, the drive gear 10 drives the adjusting ring 7 to rotate through the tooth block. The adjusting ring 7 rotates on the sleeve 6 through the docking ring 8 and the docking groove 9. The rotating adjusting ring 7 pushes the drive rod 4 to move up and down through the thread. The drive rod 4 drives the scraper 3 to move up and down synchronously, which is conducive to the scraper 3 scraping and cleaning the sediment on the inner wall of the tank 1. Then, it is only necessary to remove the cover 2 and take out the scraper 3 to clean the sediment on the scraper 3.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
