Description

Technical Field

[0001] This utility model belongs to the field of waste liquid treatment technology, specifically relating to a waste liquid recycling treatment device for electrophoretic coating. Background Technology

[0002] Electrophoretic coating is a coating technology that uses an external electric field to cause pigments and resin particles in an electrophoretic solution to migrate directionally and deposit on the substrate surface. It achieves efficient coating based on complex electrochemical reactions such as electrophoresis, electrodeposition, electrolysis, and electroosmosis. In the electrophoretic coating process of automotive parts, the long-term use of the electrophoretic solution inevitably leads to impurities and performance degradation, requiring regular treatment to maintain coating quality and environmental standards.

[0003] However, traditional electrophoretic coating wastewater treatment equipment generally uses dedicated treatment tanks for wastewater treatment, whose function is limited to simple stirring and cannot meet the needs of modern high-efficiency treatment. Because impurities in the electrophoretic coating solution easily adhere to the inner wall of the treatment tank, this not only hinders the thorough mixing of the wastewater and chemical agents during stirring, leading to low treatment efficiency, but also leaves residual impurities on the tank walls after treatment, making them difficult to clean, increasing equipment maintenance costs and operational difficulty, and affecting the stability and treatment effect of subsequent processes. Based on the above problems, this application proposes an electrophoretic coating wastewater recycling treatment device to improve these issues. Utility Model Content

[0004] The purpose of this invention is to provide a waste liquid recycling treatment device for electrophoretic coating. It can drive a rotating sleeve rod to rotate through a gear transmission structure driven by a motor. A connecting rod and a scraper are fixed on the outside of the rotating sleeve rod. The rotation of the connecting rod and the scraper can not only stir the waste liquid and promote the thorough mixing of the waste liquid with chemical agents, but also remove impurities attached to the inner wall of the treatment tank during the stirring process, thereby improving the efficiency and quality of waste liquid pretreatment.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] Please see the appendix Figures 1 to 3 As shown, this utility model provides an electrophoretic coating waste liquid recycling treatment device, including a discharge box 10, a treatment box 11 fixed to the upper end of the discharge box 10, a support plate 12 fixed to the upper end of the treatment box 11, a motor 13 fixed inside the support plate 12, the output end of the motor 13 passing through the interior of the support plate 12 and extending to the outside, a first gear 14 fixed to the output end of the motor 13, a second gear 15 rotatably connected inside the support plate 12 and located below the first gear 14, and the first gear 14 and the second gear 15 meshing together, a rotating sleeve 16 fixed to the lower end of the second gear 15, and the lower end of the rotating sleeve 16 passing through the support plate 12 and extending into the interior of the treatment box 11, a connecting rod 17 fixed to the outside of the rotating sleeve 16 and located inside the treatment box 11, and a scraper 18 fixed to the end of the connecting rod 17 away from the rotating sleeve 16.

[0025] In this embodiment, by starting the motor 13, the output end of the motor 13 rotates, driving the first gear 14 to rotate. The first gear 14 meshes with the second gear 15 to rotate, thereby causing the rotating sleeve 16, which is fixed to the lower end of the second gear 15, to rotate inside the treatment tank 11. The connecting rod 17 on the outside of the rotating sleeve 16 rotates with it. The rotation of the connecting rod 17 drives the scraper 18 to rotate. The rotation of the connecting rod 17 and the scraper 18 can stir the waste liquid in the treatment tank 11, so that the waste liquid and chemical agents can be fully mixed. Moreover, during the stirring process, the impurities attached to the inner wall of the treatment tank 11 can be cleaned off, making it convenient to use for stirring or scraping, and preventing impurities from adhering to the tank wall.

[0026] In a preferred embodiment, please refer to Figure 3 The inside of the rotating sleeve 16 is rotatably connected to a nozzle 19. The upper end of the nozzle 19 extends to the upper end of the support plate 12. A third gear 20 is fixed on the outside of the nozzle 19 and inside the support plate 12. The third gear 20 is located above the first gear 14. The first gear 14 and the third gear 20 are meshed together. A rotary joint 21 is provided at the upper end of the nozzle 19. Multiple nozzles 22 are provided on the outside of the nozzle 19 and inside the processing box 11. The multiple nozzles 22 are equidistantly distributed.

[0027] In this embodiment, when the motor 13 drives the first gear 14 to rotate, the third gear 20, which meshes with the first gear 14, drives the nozzle 19 to rotate within the rotating sleeve 16. The nozzle 19 is connected to the cleaning fluid through the upper rotary joint 21. Multiple equidistant nozzles 22 located outside the nozzle 19 rotate synchronously with the nozzle 19, evenly spraying the cleaning fluid onto the inner wall of the treatment tank 11 for thorough cleaning by the scraper 18. It should be noted that because the nozzle 19 and the water guide pipe are connected through the rotary joint 21, the water guide pipe will not become tangled when the nozzle 19 rotates.

[0028] Secondly, please refer to the following as well. Figure 2 and Figure 3 A water pump 25 is fixed to the upper end of the support plate 12, and a water storage tank 26 is fixed to the upper end of the treatment box 11. The water pump 25 and the water storage tank 26, as well as the third gear 20 and the water pump 25, are all connected by water pipes.

[0029] In this embodiment, the water pump 25 is connected to the water storage tank 26, which can extract and transport the treatment liquid or cleaning liquid in the water storage tank 26 in a timely manner, ensuring the continuity and stability of the liquid supply and providing a sufficient liquid source for the spraying operation of the nozzle 19 and the spray head 22.

[0030] To further understand and explain, Figure 2For example, a cylinder 27 is fixed at the upper end of the processing box 11, and a connecting plate 28 is fixed at the output end of the cylinder 27. The connecting plate 28 and the support plate 12 are fixedly connected.

[0031] In this embodiment, the telescopic movement of cylinder 27 drives the connecting plate 28 and support plate 12 to move up and down, thereby adjusting the vertical position of components such as the rotating sleeve 16 and spray nozzle 19 installed on the support plate 12. This adapts to the waste liquid treatment needs at different liquid levels and improves the equipment's operational adaptability. Furthermore, adjusting the height of the support plate 12 changes the immersion depth of the spray nozzle 19 and nozzle 22, enabling precise control of the liquid spraying range of the nozzle 22 and the stirring intensity of the connecting rod 17 and scraper 18, thus optimizing the process effects at different treatment stages.

[0032] In a preferred embodiment, please refer to Figure 1 and Figure 2 The processing box 11 is equipped with a filter plate 29 inside, and an inlet pipe 30 is provided at the upper end of the processing box 11. A filter screen 31 is provided inside the inlet pipe 30.

[0033] In this embodiment, the filter screen 31 is located inside the inlet pipe 30, which can initially intercept larger particulate impurities when the waste liquid first enters the treatment tank 11, preventing them from clogging subsequent pipelines or interfering with the treatment process. The filter plate 29 inside the treatment tank 11 can further separate residual impurities or reaction precipitates during the waste liquid treatment process. This dual filtration mechanism effectively improves the cleanliness of the waste liquid, providing a high-quality pretreatment foundation for subsequent deep purification and recycling. It should be noted that the diameter of the filter holes in the filter screen 31 is larger than the diameter of the filter holes in the filter plate 29. It should also be noted that when the filter plate 29 is fixed inside the treatment tank 11, the electrophoretic coating waste liquid inside the treatment tank 11 will not flow out.

[0034] Secondly, please refer to again Figure 1 One end of the discharge box 10 is provided with a drain pipe 32, and a valve 33 is provided on the outside of the drain pipe 32.

[0035] In this embodiment, valve 33 can control the timing and flow rate of the treated waste liquid discharged from the discharge tank 10 as needed, which allows operators to flexibly adjust according to the processing progress and avoid waste liquid overflow or untimely discharge.

[0036] The working principle of this utility model is as follows:

[0037] Electrophoretic coating waste liquid enters the treatment tank 11 through the inlet pipe 30. The filter screen 31 inside the inlet pipe 30 first intercepts larger particulate impurities to prevent them from interfering with subsequent treatment processes. The motor 13 is started, and its output end drives the first gear 14 to rotate. Through meshing, the first gear 14 drives the second gear 15 and the third gear 20 to rotate. The second gear 15 drives the rotating sleeve rod 16, connecting rod 17, and scraper 18 to rotate, stirring the waste liquid, separating solid impurities and preventing impurities from adhering to the tank wall. The third gear 20 drives the spray pipe 19 to rotate. The spray pipe 19 is connected to the cleaning liquid through the rotary joint 21, and the outer nozzle 22 sprays the cleaning liquid evenly, which can both assist in stirring and clean the tank wall. At the same time, the water pump 25 draws and delivers the treatment liquid or cleaning liquid from the water storage tank 26 to provide sufficient liquid for the spray pipe 19. During the treatment process, the cylinder 27 can extend and retract to drive the support plate 12 to rise and fall, adjust the position of the rotating sleeve rod 16 and the spray pipe 19, control the stirring and spraying intensity, and adapt to different treatment stages and liquid levels. The filter plate 29 inside the treatment tank 11 further separates residual impurities. The treated waste liquid flows into the discharge tank 10. The operator can adjust the discharge timing and flow rate as needed by controlling the valve 33 outside the discharge pipe 32 to complete the waste liquid recycling treatment.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
